Setting up payment processing for a small business can be done in six steps: sorting out a business entity and bank account, choosing the processor that fits your needs, adding checkout to your website, configuring invoicing, adding subscription billing, and finally, connecting it all to your bookkeeping. Choosing your processor is arguably the most important step. The difference between fair processing rates and the most expensive option can be $100 or more per month on a processing volume of $10,000 – and this difference grows alongside your sales. In this guide, we'll explain how to set up your [online payment processing](https://whop.com/blog/accept-payments-online/) step by step. If you also sell at events or IRL, the in-person section near the end covers what changes. ## What payment processing for a small business actually involves Payment processing involves multiple moving parts that route the money from your customer's card through the banking network to your business account. A payment gateway is what securely captures and encrypts your customer's payment details at checkout, and passes them on to the payment processor. Think of it as the connection between your checkout and the systems that handle the remainder of the transaction (hence "gateway"). The payment processor then takes the information collected from the gateway, and communicates it to the relevant banks to get the payment approved or declined. While gateways and processors serve different purposes, most modern payment providers include both, so you can accept payments through a single integration. Once a payment gets approved by the banks involved, it settles through a merchant account before being paid to your business bank account. You can set up a merchant account for your business, which typically requires underwriting upfront, or you can use an aggregator (like Whop, Stripe, or PayPal). An aggregator allows businesses to accept payments under its own merchant account, rather than requiring each business to open a dedicated one. It's faster to set up, and where most small businesses start out. Payouts typically take 1–3 business days, depending on your provider and setup. Some providers hold funds in a balance you withdraw from, and many offer instant payouts for an additional fee. To put the above flow to work, an online-first business needs four things: - A checkout method – like a hosted page, embedded checkout, or payment links that can [accept card payments](https://whop.com/blog/take-credit-card-payment/) with digital wallet support (Apple Pay, Google Pay) - Invoicing for services or custom work - Recurring billing if you sell subscriptions or services on a retainer - Reporting that syncs with your bookkeeping Running a storefront? You'll need most of the above plus a card reader and POS software. Check out our guide to [Stripe vs Square](https://whop.com/blog/stripe-vs-square/). ## Step 1: Set up your business entity and bank account Before you can accept payments, you need to decide how your business will operate legally and where you'll receive your payouts. You don't need to [form an LLC](https://whop.com/blog/start-an-llc-guide/) or corporation to get started; sole proprietors can accept payments using their own legal name and Social Security Number (SSN), while registered businesses typically provide their legal business name and Employer Identification Number (EIN). The main difference between the two is liability. A sole proprietor is personally responsible for the business's obligations, while an LLC is a separate legal entity that generally provides liability protection and shields your personal assets. For underwriting, the choice matters less than people expect. Some providers view an LLC with its own EIN and bank account favorably, but it doesn't automatically make processor approval any easier, or eliminate personal verification requirements. The provider checks the owner's identity either way. If you haven't established your business yet, see our [guide to starting a business](https://whop.com/blog/how-to-start-a-business/) for the steps involved. If you are operating as an [LLC or corporation](https://whop.com/blog/llc-vs-c-corp/), you'll generally want a dedicated business checking account in your company's legal name. Most banks require your EIN, formation documents, business address, and personal identification to open one. Sole proprietors may be able to receive payouts into a personal bank account, depending on their bank's rules and payment provider. However, opening a separate business account makes it easier to track revenue, manage expenses, and keep your bookkeeping organized. Once your bank account is set up, you can apply to a payment provider. Your payment processor needs to verify who you are, what your business does, and where to send your money. This is part of KYC (Know Your Customer) and KYB (Know Your Business) checks, which are how payment providers verify businesses and their owners, prevent fraud, and meet regulatory requirements. Have these details ready: - Your legal name, date of birth, address, and SSN or other accepted identification - Your business name, business address, EIN (if applicable), and a description of what you sell - Your business bank account and routing numbers for payouts - Your website URL, or information about how and where you sell Your processor may also request formation documents, proof of address, or financial information, depending on your business and risk profile. New accounts may have longer initial payout periods while the payment provider completes its checks. Stripe's payout docs state that it holds the first payout for 7–14 days; funds on Whop can be withdrawn 1–4 business days after a sale, and a standard withdrawal takes up to 5 business days to land (with some withdrawals flagged for a manual compliance review). Some businesses may also face temporary payment holds or reserves, so don't assume your first sales will be available to withdraw immediately. ## Step 2: Choose a processor that fits online sales The right payment processor for selling online depends on what you sell, how much you process, and how your customers prefer to pay. Before locking in a provider, compare your options on the criteria below. - **Pricing model:** Does the provider charge a fixed rate per transaction, pass through interchange costs, or combine transaction fees with a monthly subscription? - **Minimum fees:** Are you required to process a minimum amount each month, or charged a fee if you fall below that threshold? - [**Chargeback**](https://whop.com/blog/chargebacks/) **fees:** How much will you pay if a customer disputes a transaction? Are you refunded the fee if you win the dispute? - **Payout speed:** How long does it take for sales revenue to reach your business bank account? Are faster payouts available? - **Payment methods:** Can customers pay using their [preferred payment method](https://whop.com/blog/payment-methods/) (credit and debit cards, digital wallets, bank transfers)? - **Reach:** How many countries and territories does the provider accept payments in? Do they support local payment methods? For online businesses selling cross-border, this is an important factor. - **Integrations:** Does the processor work with your website, ecommerce platform, or checkout? Will you need custom integration? ### Understanding different pricing models Most [payment processors](https://whop.com/blog/payment-processors/) use one of three pricing approaches:
Pricing model How it works Example rate Best for
Flat rate One percentage plus a fixed fee on every transaction, regardless of card type 2.9% + $0.30 New and lower-volume businesses that want predictable costs
Interchange plus Interchange and card network fees are passed through at cost, plus a fixed provider markup Interchange and network fees (~2.1% on a $50 sale) + 0.5% + $0.25 Businesses with higher average order values that can handle costs varying month to month
Subscription A fixed monthly fee plus interchange at cost and a small per-transaction fee, with no percentage markup $99/month + interchange and network fees + $0.15 Businesses with enough volume to spread the monthly fee
### How to calculate what payment processing will actually cost The advertised percentage doesn't tell you the full cost of accepting payments. Your average transaction size, number of transactions, and any fixed fees all affect what you'll pay. Say your business processes $10,000 per month across 200 transactions averaging $50 each. Here's what that volume would cost under different pricing structures:
Pricing model Rate Monthly cost Annual cost Annual difference vs. interchange plus
Interchange plus* ~2.08% + 0.5% + $0.25 $308 $3,696
Lower flat rate 2.7% + $0.30 $330 $3,960 +$264
Subscription $99/month + ~2.08% + $0.15 $337 $4,044 +$348
Standard flat rate 2.9% + $0.30 $350 $4,200 +$504
Higher flat rate 3.49% + $0.49 $447 $5,364 +$1,668
**Interchange and network fee estimates based on Helcim's online pricing calculator (2.58% + $0.25 all-in for Visa, Mastercard, and Discover on a $50 transaction, checked October 2026), less its 0.50% + $0.25 markup. The ~2.08% is an effective rate that includes interchange’s fixed per-transaction fee.* Interchange plus comes out cheapest in the example above, but only just. That's because interchange includes a small fixed fee on every transaction as well as a percentage, and on smaller sales that fixed fee makes up a bigger share of the cost. Helcim's calculator puts its all-in online rate at 2.58% + $0.25 on a $50 sale, compared with 2.31% + $0.25 on a $300 sale. The smaller your average order, the less interchange plus saves you over a [low fee payment processor](https://whop.com/blog/low-fee-payment-processors/). Premium rewards cards, American Express, and international cards generally cost more to process, while debit cards usually cost less. Your interchange plus costs will rise and fall with your customers' card mix each month, while a flat rate stays the same. ### Which model should you choose? As a general rule, if you process under about $10,000 a month with small average orders, a low flat rate will cost about the same as interchange plus and is simpler to manage. Past that point, it's worth getting an interchange plus quote and testing it against a few months of your real transactions rather than an estimated average. **Subscription pricing only tends to pay off at higher volumes:** at a $50 average order, the $99 fee is covered by the lower per-transaction costs at around $9,000 a month compared with a 2.9% + $0.30 flat rate, $11,000 compared with 2.7% + $0.30, and $14,000 compared with interchange plus. ## Step 3: Add checkout to your website or storefront With your payment processor selected, it's time to set up a way for customers to pay. You don't necessarily need to build a checkout from scratch – most payment providers offer ready-made options you can connect to your website or share directly with customers. There are four common ways to add checkout: - **Hosted checkout page:** Customers are redirected to a secure payment page managed by your provider. Easy to set up because you don't need to build or maintain the checkout yourself. - **Embedded checkout:** An embedded form appears directly on your website, so customers can complete their purchase without leaving the page. This gives you more control over the checkout experience but may require additional integration work. - **Payment links:** Generate a link to a payment page and share it by email, text, social media, or anywhere else you communicate with customers. This works well for service businesses, one-off purchases, and businesses that don't own a website. - **Platform-native checkout:** If you use an ecommerce platform or storefront builder, you can often enable payments directly through its settings. This is generally the simplest option for businesses already selling through a platform. Ontario dog training academy, iTK9, sends a checkout link within minutes of each free assessment call, so clients can commit while the decision is fresh rather than waiting on an invoice. Before you go live with your checkout, run a test transaction to confirm: - Customers can pay by card and supported digital wallets, including Apple Pay and Google Pay - Your checkout works properly on mobile, including payment forms, buttons, and redirects - Any applicable sales tax is calculated and collected correctly, either through your provider's tax tools or a separate integration - Customers receive an order confirmation or payment receipt after a successful transaction - Refunds work end to end, and you know whether your processor returns the transaction fee If you sell products, services, or memberships, Whop gives you three of the four options above: a storefront with built-in checkout, checkout links you can share anywhere, and an embeddable checkout element for your own site that needs no server code. **[Embed a checkout with Whop](https://docs.whop.com/developer/guides/embed-checkout)** ## Step 4: Send invoices for one-off and service work Checkout alone isn't enough for all online businesses: some need invoicing – especially when selling B2B, offering services, or giving custom quotes. Instead of collecting payment upfront, you send customers an invoice outlining what they owe and when payment is due. This works particularly well for freelance projects, consulting, custom orders, and services where the final price is agreed upon individually. Each invoice should include: - **Your business and customer details:** Names, contact information, and billing addresses - **Description of goods or services:** What you're charging for, including quantities, rates, and any applicable taxes - **Invoice number and issue date:** A unique reference for tracking the payment and when the invoice was issued - **Payment terms and due date:** When payment is expected, such as immediately upon receipt or within 30 days - **Payment link:** A way for customers to pay directly from the invoice, ideally with multiple payment methods available Many payment processors offer [invoicing](https://whop.com/blog/best-invoicing-software/) alongside checkout, so if you need it, check that your chosen processor has the capability. This will also allow you to send payment reminders and track which customers have paid. Daniel Petrovskiy, owner of Pinnacle North West Kitchen & Bath, moved his invoicing off an accounting platform he found slow and cluttered onto Whop. Each invoice now carries a due date, a work description, and a choice of card or ACH, with automatic follow-ups on late payments. Some providers also let you pass the processing fee on to the customer, though card surcharging is restricted in some US states and requires clear disclosure, so check the rules before turning it on. Bank transfers through ACH can often be cheaper, particularly for larger invoices, because percentage-based ACH fees usually come with a cap. With Whop, a $2,000 invoice costs $54.30 by domestic card (2.7% + $0.30) and $5 by ACH (1.5%, capped at $5). If you bill retainers, a recurring invoice typically creates a subscription, which is what Step 5 covers. ## Step 5: Set up recurring billing if you sell subscriptions or retainers If you're planning to charge your customers on a recurring basis (think product subscriptions, memberships, service retainers, or SaaS), you'll need a checkout that supports recurring charges. A recurring billing system is able to automatically charge your customers at agreed intervals and handles what happens when circumstances change. Look for a solution that handles: - **Automatic payments:** Charges customers on a set schedule, such as weekly, monthly, or annually, without requiring them to check out again. - **Failed payment retries and dunning:** Retries declined payments and sends customers reminders to update their payment details before their subscription is canceled. According to Recurly's 2026 State of Subscriptions report, 9% of subscription renewal payments are declined, but 53% of failed payments on monthly plans are recovered. - **Proration:** Adjusts charges when customers upgrade, downgrade, or change plans partway through a billing cycle. - **Cancellations:** Lets customers cancel their subscriptions themselves, and stops future charges according to your cancellation policy. Failed recurring payments don't always mean the customer wants to cancel. Sometimes it's simply an expired card, late paycheck, or change of details – according to Stripe, its automated Smart Retries feature recovers an average of 57% of recurring payments that initially fail. Some billing solutions also let your customers keep access during this retry period, which, in the case of accidental failed payments, keeps them happy. You have three main options for managing recurring payments: - **Processor-native subscriptions:** Use your payment processor's built-in subscription features. For example, Stripe Billing's pay-as-you-go pricing starts at 0.7% of billing volume, on top of [payment processing fees](https://whop.com/blog/payment-processing-fees/) – for sales totaling $10,000, that's an extra $70 a month for billing, or $840 per year. - **Standalone billing software:** Tools like Chargebee and Recurly offer subscription management, payment recovery, and billing automation, with pricing that may combine a monthly subscription and a percentage of revenue. You just need to factor in the cost of running these alongside your payment processor. - **Platforms with built-in memberships:** Whop has memberships and subscriptions with recurring payments built in. The billing feature adds automated invoice generation, failed payment retries, and subscription lifecycle management for 0.5% per transaction, on top of the standard 2.7% + $0.30 card processing rate. That's about $50 a month on $10,000 of renewals. ## Step 6: Connect payments to your bookkeeping Your payment processor records how much your customers pay, but your bank account only shows what you receive after fees, refunds, and other adjustments. To keep your books accurate, you need to reconcile the two. Let's use an example of $10,000 in monthly sales, processed across 200 transactions of $50 each. We'll use Whop's rate of 2.7% + $0.30, and account for processing fees of $330, refunds totaling $200, a chargeback amount of $50 (one sale), and a $15 chargeback fee. ![](https://storage.ghost.io/c/12/7b/127b828b-bdc2-4972-9cf2-de857df9c324/content/images/2026/10/-10-000-in-monthly-sales.png) Your bank account would show $9,405 for the month, even though you made $10,000 in sales. Your bookkeeping needs to show where that $595 difference went, rather than recording $9,405 as your total sales. There's also a timing difference to account for – payment processors often combine multiple transactions into a single bank payout, and some payments might not arrive until the following month. When checking your records, make sure every sale, deduction, and payout is accounted for, including money that's still on its way to your bank. ### Automating your accounting records Instead of manually entering every transaction (seriously, who has the time for that), you can connect your payment processor to [accounting software](https://whop.com/blog/best-software-for-small-business/) that can import sales, refunds, fees, and payouts. These are called accounting integrations, and most processors have multiple options. Whop integrates with QuickBooks and Xero. The QuickBooks integration supports syncing sales, refunds, payouts, and processing fees (in All Sales mode). With Xero, the integration imports sales, fees, refunds, lost chargebacks and payouts as separate statement lines. **[Whop accounting integrations](https://docs.whop.com/third-party-integrations/quickbooks)** When connecting any payment processor to your accounting software, check exactly what information it syncs. Ideally, you want visibility into individual sales, fees, refunds, and payouts, rather than just the final amounts deposited into your bank account. Otherwise, you may still need to enter those details manually. ### Monthly payment reconciliation checklist To reconcile data correctly at the end of each month: 1. **Match payouts to bank deposits:** Confirm that the payouts recorded in your accounting software match the deposits into your bank account. QuickBooks can automatically record Whop payouts in All Sales mode; Xero imports payout activity for reconciliation. 1. **Review processing fees:** Check that fees have been recorded separately from sales revenue. Whop's QuickBooks integration can automate this, while Xero imports fee transactions for you to reconcile. Compare the totals against your processor's monthly fee report to catch missing charges. 1. **Check refunds and chargebacks:** You should verify that refunded amounts and dispute fees are accounted for. Check your processor's dashboard for unresolved disputes – these can potentially impact future payouts. 1. **Account for pending funds:** Payments processed near the end of the month might not reach your bank until the next month because of payout timing. Check your processor's balance for pending payouts, holds, and reserves so you don't mistake a timing difference for missing money. 1. **Watch out for duplicate revenue:** If individual sales are already recorded, make sure their corresponding payouts aren't counted as additional income. This is particularly important when using Whop's QuickBooks Withdrawals Only mode alongside invoices you already record in QuickBooks, or when matching imported transactions in Xero. The goal isn't to manually redo your bookkeeping each month, it's to verify that the automated records match what actually occurred. This helps you catch errors before they affect your reports. ## How to avoid overpaying: six common fee traps It's appealing to look at headline transaction rates and jump at the lowest. But failing to read the fine print is how many small businesses end up paying more than they bargained for. Before choosing a provider, check them against these six costs that can push your fees higher than you expected. - **Monthly minimums:** Some merchant account providers charge a minimum amount in processing fees each month, even when your sales are slow. For example, if your monthly minimum is $25 but you only generate $10 in eligible fees, you could owe another $15. - **PCI compliance fees:** PCI compliance means following the Payment Card Industry Data Security Standard (PCI DSS), a set of security requirements designed to protect customers' card information when accepting, processing, or storing payments. Some providers charge separately for this. Whop has no PCI fee, and that holds whether you use a checkout link or embed checkout on your own page: either way the [card fields](https://docs.whop.com/elements/latest/payments/cardFields) are Whop's, not yours. With merchant account providers, failing to complete the annual questionnaire for PCI compliance will mean incurring a non-compliance fee of $20 to $100 a month. - **International card surcharges:** Customers don't necessarily have to be from overseas for international card fees to apply. Some processors charge based on where the card was issued, not where the purchase takes place. A common benchmark is 1.5% on top of the base transaction fee – which both Stripe and Whop charge for international cards. Currency conversion fees will also typically apply, so check for both and factor them in. When you're selling online, [cross-border payments](https://whop.com/blog/cross-border-payments/) are likely. - **Early termination fees:** Some merchant services agreements lock you into multi-year terms, and you'll be charged for leaving early. Before signing on, check the contract length, cancellation notice period, and whether termination costs are fixed or calculated from your remaining expected fees. Pay-as-you-go processors (like Whop, Stripe, Square, and PayPal) have no contract or early termination fee; many merchant account services do. - **Paying card rates when ACH is available:** ACH bank payments can be cheaper to process than card payments, especially if you're selling high-ticket items, subscriptions, or retainers. Whop charges 1.5% capped at $5 for ACH payments – on a $500 retainer, that's $5 vs. $13.80 paid by card. Check if your provider offers ACH as a checkout option. - **Platform fees stacked on processing fees:** Depending on where you're selling, some platforms will charge their own fee on top of your payment processor's fee. For example, Shopify's basic plan includes a 2% fee if you use a third-party processor. On $10,000 a month of sales, that's $200 a month in extra fees. Early termination fees are not a hypothetical: in 2022 First American Payment Systems agreed to pay $4.9 million to settle FTC charges that it sold small businesses on contracts with no cancellation fee that in fact auto-renewed on three-year terms with a $495 fee to leave. ## When you need in-person payments too If you sell at events, markets, or split between online and counter sales, you'll need in-person payments, and that means a card reader, POS system, or a compatible smart device that can accept tap to pay. In-person processing rates can differ from online rates, so compare both if you sell across multiple channels. - **Full POS setups:** These typically incur hardware costs, and your processor will typically offer a few options. Check out our [Stripe vs. Square](https://whop.com/blog/stripe-vs-square/) comparison to understand how their in-person and online options compare. - **Simpler setups:** Many providers, including Whop, PayPal, and Square, offer [tap to pay](https://whop.com/blog/tap-to-pay-guide/) solutions so you can accept payments on the go using your smartphone or another NFC-enabled device. Rates can vary. Whop's [Tap to Pay on iPhone](https://whop.com/blog/tap-to-pay-on-iphone/) solution follows the same transaction rate as standard card payments. ## Accept your small business payments with Whop ![Video thumbnail](https://storage.ghost.io/c/12/7b/127b828b-bdc2-4972-9cf2-de857df9c324/content/media/2026/03/wpn_thumb.jpg) [Watch video](https://storage.ghost.io/c/12/7b/127b828b-bdc2-4972-9cf2-de857df9c324/content/media/2026/03/wpn.mp4) Whop gives small businesses everything they need to accept online payments, with transparent fees and no monthly or setup costs for merchants.

Online card processing typically costs between 2.5% and 3.5%, plus a fixed fee per transaction. On $10,000 a month in sales across 200 transactions, a flat rate of 2.9% + $0.30 costs $350, compared with $330 at a rate of 2.7% + $0.30. That alone is a $240 difference over a year. Interchange plus pricing can cost less, but it depends largely on your transaction volume and customers' card types. ### Do I need a merchant account? No. Merchant account providers can be worth considering if you have high processing volume and can negotiate rates, but aggregators like Whop, Stripe, Square, and PayPal let you process payments under their existing merchant account arrangements. This means smaller businesses can get set up to accept payments faster. ### How do I accept payments as a small business without a website? If you don't have a business website, you can accept payments using payment links, digital invoices, or hosted checkout pages. These allow your customers to pay securely without you needing to build your own checkout. Whop lets you create an on-platform storefront with built-in checkout so you can sell products, services, memberships, and subscriptions without setting up a separate website. ### What is the cheapest way to accept payments online? ACH bank transfers are often among the cheapest options for accepting online payments, especially for larger transactions and where fees are capped. For card payments, interchange plus pricing can be more cost effective at higher volumes, while flat-rate processors may offer better value and predictability for smaller businesses. Compare total costs including any monthly and platform fees rather than looking at transaction rates alone.
