The invoice is the easy part. Getting paid is the job.

Most unpaid invoices are not disputes. They are invoices nobody remembered to chase, sent to someone who forgot, and left until the freelancer got annoyed enough to write an awkward email.

Reminders that run on the phone

Turn reminders on and every unpaid invoice gets two: one at 9am on the due date, one three days after. Tap either and it opens that invoice.

They are scheduled by the phone itself — there is no push server, no notification token, and they fire whether or not the device has been online. The offline promise holds.

Three tones, written for you

Open an unpaid invoice, tap Send reminder, and choose how firm to be:

• Friendly nudge — for day one, when it is probably just buried
• Professional notice — for week two, referencing the terms
• Final demand — for the point where politeness has done its work

Each one goes out on WhatsApp with the amount, the invoice number and the due date filled in. The full four-stage escalation, including what to do at day thirty.

Know what is outstanding, by age

The home screen shows what is billed, what is paid and what is overdue. The clients screen sorts by who owes you most, with overdue balances in red.

Ageing matters more than the total — £3,000 that is ninety days old is a different problem from £10,000 that is a week old.

Statements for clients with several invoices

One PDF showing everything a client has been billed, what they have paid, and the balance. Usually more effective than forwarding four separate invoices, because it makes the total unavoidable.
