Common Questions
How is this different from emailing a PDF?
Customers open a secure link, review the invoice, and choose a supported payment option without creating an account.
What are the payment processing fees?
Payment processing rates depend on the payment method and your connected account. Ask us for the rates that apply to your setup.
Can I offer payment plans?
Customers can apply for financing through our Wisetack integration and pay over time; you get paid in full.
Do you support deposits and progress payments?

Mark invoices as "paid by check" and record manually. Check payments remain available for customers who prefer them.
