Get paid on time. Without the awkward chasing.
CashRelay sends polite, well-timed reminders for your unpaid invoices, reads every reply, and only brings you in when a person should decide.
The demo opens a private sample company in seconds. No sign-up, fictional data, nothing is emailed.

Late payment is holding UK businesses back
Chasing money you are already owed takes time you don't have, and gets awkward fast.

How it works
Four steps. You only need to be involved when something needs a decision.
Bring your invoices
Upload unpaid invoices from your accounts software. Every balance is checked to the penny before anything is saved.
Reminders at the right time
Friendly first, firmer later. Working days only, never before an invoice is due, and you approve them before they go.
Replies read for you
Promises pause reminders. Disputes, “we've paid” and anything unclear come straight to you, with the customer's words.
Payments settle it
When money arrives, the balance updates and any reminder still waiting is stopped, so no one is chased for a paid invoice.
Every reply, handled properly
Customers reply in their own words. CashRelay reads each one and does the sensible thing, and it shows you exactly what it read.
AI can help read replies, but fixed rules decide what happens. It never decides what is owed.

Your day, on one screen
Open CashRelay in the morning and see exactly what needs you. Everything else is already in hand.
- Approve reminders with one click, after reading the exact email
- Disputes and payment claims at the top, with the customer's words
- Overdue, promised and collected totals, always up to date
Every invoice tells its whole story
The balance, any dispute or promise, every reminder and reply, and a ledger of every penny in and out.
- The customer's exact words behind every decision
- Record a payment or a promise in seconds
- The whole conversation, in order, and a ledger that always adds up
Import in minutes, checked to the penny
Upload a spreadsheet from any accounts package. Problems are shown row by row before anything is saved.
- Totals, payments and balances must add up exactly
- Impossible dates and duplicates are caught
- Importing the same file twice is harmless
A full history you can trust
Every reminder, reply, decision and payment is recorded, with who or what made it. Nothing can be edited after the fact.
- See whether a person, the rules or an outside system acted
- Useful for your accountant, and for any disagreement
- Works on your phone as well as your computer
Built for the way UK businesses work
Working days, not calendar days
Reminders skip weekends and England & Wales bank holidays, and never go before an invoice is due.
Pounds and pence, exactly
No rounding, ever. Part payments are shown clearly and every reminder quotes the live balance.
Polite British English
Friendly first, firmer later, and never threatening. After the final reminder, CashRelay stops and asks you.
Paid means stop
A reminder is checked again just before it goes. If the invoice has just been paid, it isn't sent.
Your data, walled off
Each company's data is kept apart by the database itself, and checked by automated tests.
Hosted in London
The service and its database run in London data centres.
You decide how much it does on its own
Start by approving everything. Hand over more when you're comfortable. Change it any time.
Join the pilot
We're inviting a small number of UK businesses to use CashRelay with their own invoices and help shape what we build next. We'll set you up personally.
Straight answers
Will it email my customers without me knowing?
No. By default every reminder waits for your approval, with a preview of exactly what will be sent. You can later choose to approve only the first reminder to each customer, or let reminders go automatically.
Does AI decide what my customers owe?
No. Balances only change when a real payment is recorded. AI can help read replies, but fixed rules decide what happens next, and anything unclear comes to you. It never offers discounts, changes bank details or makes threats.
What happens if a customer disputes an invoice?
Reminders for that invoice stop immediately and it goes to the top of your list with the customer's own words. Nothing else is sent until you mark it resolved.
What if they pay while a reminder is waiting to go?
The reminder is withdrawn. Every reminder is checked again just before it is sent, so a customer who has just paid is not chased.
Which accounting software does it work with?
Today you upload a spreadsheet (CSV) of unpaid invoices from any accounting package. A direct Xero connection is planned next.
Is this a debt collection agency?
No. It helps you chase your own invoices politely and consistently, and tells you when a person needs to step in. It does not take legal action or add fees.
Where is my data kept?
The service and its database run in London. Each company's data is walled off from every other company's by the database itself, and every action is recorded in an audit log.
