Invoice Reminder App Checklist

Use this printable checklist to compare software for a UK small business before unpaid invoices become manual chasing.

Payment rules

• Every invoice has plain payment terms, a due date, and a clear payment method.
• The app can schedule pre due, due date, and overdue reminders.
• Reminder wording can stay human while still including amount, invoice number, and next action.

Status checks

• Paid, unpaid, overdue, part paid, disputed, and promised payment states are easy to see.
• Card, bank transfer, cash, and part payment notes prevent accidental chases.
• Disputes pause normal reminder sequences and keep a contact trail.

Service business fit

• Client notes, appointment details, completed work, and invoice records are connected.
• The mobile view is good enough to update payment status between appointments.
• Weekly bookkeeping review shows overdue invoices beside income, receipts, and fees.
