How it works

Three steps. Then it runs itself.

Send your invoice as normal. Dunn handles every reminder automatically — stopping the moment your client pays.

01

Create your invoice

Build a professional, HMRC-compliant invoice in under a minute. Dunn attaches a branded payment link — clients pay in one tap.

60 seconds
02

Automated reminders

Friendly notice before the due date. Firm reminder on the day. Final notice at 7 days overdue. Every message sounds personal — never automated.

Zero effort
03

Get paid. Move on.

Your client pays via their branded payment page. Dunn marks it as settled, stops all reminders, and logs it to your payment history.

Smart reminders

Adapts per client — escalates to SMS when email is ignored. Optimises send times based on payment history.

Payment links

Every invoice includes a branded payment page. Stripe, PayPal, or bank transfer — your client's choice.

Dunn Verified

A shareable trust badge showcasing your collection history. Add it to quotes, proposals, and your website.

Debt recovery

One-click Letter Before Action. Pre-filled Small Claims Court filing. No solicitor required.

Client insights

Payment behaviour scores built from real data. Identify late payers before it becomes a problem.

Accountant mode

Your accountant receives a dedicated multi-client dashboard to monitor all invoices — at no extra cost.

I used to write off two or three invoices a year. Within the first month of using Dunn, I recovered £1,800 I had essentially written off.

Full recovery stack

We don't stop at a reminder.

Most tools stop at "final notice." Dunn takes you from polite nudge to recovered debt — all from one place.

UK sole traders write off an average of £8,200 in bad debt per year. Dunn is built to recover it.

T1
Automated reminders

Friendly, then firm, then final. Sent via email and SMS — stopping automatically the moment payment is received.

T2
Letter Before Action

A legally-worded LBA dispatched via Royal Mail recorded delivery. £5 service fee. Most clients settle at this stage.

T3
Small Claims filing

Pre-filled using your invoice data. £35 court fee. Step-by-step guidance — no solicitor needed.

T4
Debt recovery agency

Referral to a vetted agency for invoices over £500. No win, no fee. A small share of recovered funds applies.

Pricing

Straightforward pricing.

Start free. Upgrade when it pays for itself — which tends to happen fast.
