For UK freelancers, consultants and small service businesses
Stop chasing invoices yourself.
Keep invoicing the way you do. PurpleDue keeps track of what happens next — from the first follow-up to a clearer next step when normal chasing isn't working.
Your first 3 invoices are included. No card required.
No new invoicing tool to learn. No accounting software to switch. Nothing goes to your client without you saying so.

The reminders were never the hard part.
Plenty of tools can write a chase email. The harder part is remembering which invoice needs one, and when — while you're also doing the actual work. PurpleDue stays with each invoice from the moment you hand it over, through the ordinary follow-ups, and into the right next step if that isn't enough.
That's the whole idea: PurpleDue quietly looks after money you've already earned.
When the usual chasing isn't working
If a client still hasn't paid after the normal follow-ups, PurpleDue helps you check whether the UK's statutory late-payment rules apply, works out the interest and compensation you may be entitled to, and prepares a Formal Payment Request for you to review and send.
This is a clear, source-backed next step — not legal advice, not a solicitor's letter, and not a Letter Before Action.
You're always the one who hits send
- PurpleDue never emails your client automatically — every follow-up and Formal Payment Request is yours to review, edit and send.
- Only your sign-in email, and any other address you approve, can hand PurpleDue an invoice.
- You confirm every extracted detail — client, amount, due date — before an invoice starts being tracked.
- Your invoices go to a private PurpleDue address, not a shared inbox.
- Invoice files are stored privately — only your own account can ever access them.
Built for businesses too small to have a credit controller
Freelancers, consultants and small service businesses who already send invoices somehow, occasionally chase a late payer, and would rather not carry “who owes what” around in their head.
Running a dedicated collections or accounts-receivable team? PurpleDue isn't built for you yet.

Try PurpleDueQuestions people ask before trying it
Will PurpleDue email my client automatically?
No. PurpleDue prepares follow-ups and the Formal Payment Request, but you always review and send them yourself.
Do I have to stop using my invoicing software?
No. Keep creating and sending invoices exactly as you do now — just BCC or forward them to PurpleDue as well.
What happens after my first 3 invoices?
Those 3 keep going through tracking, follow-ups and Resolution exactly as before, whether or not you continue. To hand over a 4th invoice, continue with PurpleDue for £8.99/month.
Can PurpleDue tell if I've been paid?
Not yet, automatically — you mark an invoice as paid yourself once you've received it.
Who can send invoices into my account?
Only your sign-in email, which is trusted automatically, and any other address you explicitly approve.
Is the Formal Payment Request legal advice?
No — it's a source-backed statutory letter template, not legal advice, a solicitor's letter, or a Letter Before Action.
Does PurpleDue work outside the UK?
Not yet. The statutory late-payment support is specific to UK law, so PurpleDue is built for UK businesses for now.
