Getting a new customer costs you 5x more than getting a second order. Almost nobody I audit is set up to ask for one.
Most store owners I talk to can tell me their cost per acquisition to the cent. Ask them what percentage of customers order twice and you get a pause.
That second number is the one that decides whether you have a business or an expensive treadmill. If every customer buys once, your growth is capped by your ad budget forever.
Know your repeat rate before anything else.
Pull the last 12 months and calculate: of everyone who ordered, what percentage ordered again? For most stores it lands somewhere in the 20-30% range, and the good ones are meaningfully higher. You cannot improve a number you've never looked at.
The 30 days after delivery are worth more than the 30 days before purchase.
Everyone pours effort into the pre-purchase experience and then goes silent the second the package ships. That window — when the product just arrived and they're happiest with you — is when a second purchase is easiest and a review is free. Silence there is the most expensive marketing mistake in e-commerce.
Send three emails, not a discount code.
One: how to get the most out of what they bought, sent on delivery day. Two: a check-in and a review request a week later. Three: the natural next product, two to three weeks in. None of these need a discount. Discounting immediately after purchase teaches people to wait for sales and quietly erodes your margin.
Sell the refill, the upgrade, or the companion.
Every product has a logical follow-on. Consumables have a refill cadence — if you know the average product lasts six weeks, the email goes out at week five, not whenever. Durables have accessories and upgrades. If you genuinely can't name the second purchase for your best seller, that's a product-line gap worth fixing this quarter.
Subscriptions beat campaigns.
For anything consumable, a subscribe-and-save option converts a one-time buyer into predictable monthly revenue with no additional acquisition cost. It also makes your business dramatically easier to forecast and, if you ever sell it, worth more.
Then re-read your ad numbers.
Here's why this matters for acquisition: if your average customer buys 2.4 times instead of 1, you can afford to pay more than double for a new customer and still profit. Whoever can spend the most to acquire wins the auction. Retention is what funds that.
We build e-commerce stores for US brands at OneExpand with the post-purchase flow set up from day one, not bolted on later.
Go pull it: what percentage of your customers have ordered more than once? Post the number and I'll tell you whether it's a product problem or a follow-up problem.
