Take card payments on an invoice, at the counter, or on my phone
The letter
Customers ask to pay by card when I hand them an invoice or when they walk up to the counter. I do not want a whole new system. I need something that works with what I already use and does not make me learn a developer tool.
What I already tried
Cash and checks still work, but more people want to tap or pay from the invoice link.
What done looks like
A customer can pay on the spot or from the invoice I already send, and the payment shows up where I track money.
