Late payers cost sole traders time and cash. This offline tool keeps track of who owes you and writes the follow-ups for you.

1. Who owes me? Log invoices. Overdue ones turn orange, then red, and the tool tells you the next step (nudge at 1–7 days, firm at 8–21, final notice at 22+). Shows total owed and total overdue. Export to CSV.
2. Reminder writer. Polite, specific email and SMS templates at 4 stages (friendly nudge, firm reminder, final notice, payment-plan offer), filled in with the client, amount, days overdue and your payment details. Copy, check, send.
3. Late fee and interest calculator. Simple interest and a flat fee, with a reminder to charge only what your terms allowed upfront. Includes a sample payment-terms line for your quotes.

Made for Australian tradies, freelancers, consultants and small agencies.
