Accounts receivable, handled

You did the work.
Now get paid for it.

Nudge chases your unpaid invoices so you never have to send that email again. Connect Stripe or Xero, and it picks up what you are already owed — then escalates, on a schedule you control, until the money lands.

The ladder

One invoice.
Four escalating voices.

The hard part of chasing money is not remembering. It is finding words that get you paid without costing you the client. Nudge writes each one from the invoice's real context — the amount, the age, who they are, and everything you have already said.

Seven rungs, all yours to move

Every rung is pinned to the due date. Turn one off, shift it, or change how hard it pushes. A client marked “new” is handled a notch softer; a chronic late payer, a notch harder.

What you actually get

It sits on top of Stripe and Xero

Your invoices stay where they are. Nudge syncs them in, chases what is late, and sends clients to the payment page they already know. Nothing to migrate, nothing to re-enter.

Nothing sends without you

Every draft lands in an outbox you can read and edit. Once you trust it, switch on autopilot and the whole thing disappears into the background.

It stops the second you are paid

Paid in Stripe, paid in Xero, or paid into your bank and marked by hand — every queued reminder for that invoice is cancelled. Nobody is ever chased for money they have sent.

It knows who it is writing to

Mark a client new, valued, or a chronic late payer and every reminder shifts tone. A first-time client never gets the debt-collector voice.

Old debts do not slip through

Connect an account with invoices already 40 days late and they get an opening chase tomorrow, pitched at the tone that age deserves. Not six emails at once, and not silence.

You can see who is actually bad

An ageing report, a value-weighted days-to-payment figure, and a ranked list of who owes you most for longest. Useful at renewal time.
