Send the invoice before they leave
An invoice link by text, with your own payment link on it, gets paid faster than "pay me later".
Take a deposit on quotes
For bigger jobs, a deposit on the quote protects your time and materials.
Let reminders do the asking
Automatic, polite reminders every few days mean you never have to ask in person.
Keep the money direct
Use your own Stripe, Square or PayPal link so money reaches you directly, with no middleman and no extra cut.
