The Commercial License allows you to use the estimates to invoices system in client projects as a developer, consultant, agency or bookkeeping practice.
Install it on client systems, customize it for their workflows, integrate it into larger systems you build, and deliver it as part of your paid services.
You receive the full Python source code, customizable PDF templates, a local database, an estimate builder spreadsheet, complete documentation, sample data and 111 automated tests, so you can change the code and prove in seconds that nothing else broke.
Payment links work through Stripe, PayPal, Square, a provider you write yourself or manual bank instructions. Reminders send by email or text through eight supported providers.
Not permitted: resale, redistribution, repackaging as a standalone product, hosted service resale, marketplace distribution or use in training any AI/ML model.
