How soon should I chase an unpaid invoice?

Send a friendly confirmation the day the invoice goes out, then a reminder the day after the due date. Waiting a fortnight signals that your terms are optional and makes the eventual conversation harder.

What can I claim on a late commercial payment?

For business-to-business invoices in the UK there is a statutory right to claim interest and a fixed sum towards recovery costs once payment is overdue. Domestic customers are treated differently, so check the position before applying charges to a homeowner.

Will chasing payment cost me the customer?

Well-run customers expect it. What damages relationships is inconsistency — silence for six weeks, then a legal threat. A predictable, unemotional sequence sent automatically is read as professional, not aggressive.

Should reminders come from a person or the system?

Send them from the system under your business name for the first three stages, then have a named person make the call at the final stage. Automation handles volume; a human handles the exception.

How to Get Paid Faster: Chasing Late Payments Without Losing the Customer

Office manager reviewing outstanding invoices for a trade business

Nobody starts a trade business because they enjoy asking people for money. Yet in most field-service companies the person who chases debt is also the person answering the phone, booking the diary and ordering parts — so chasing is the job that slips. Weeks pass, the work goes cold in the customer's memory, and a straightforward payment turns into an argument.

The fix is not a tougher tone. It is a fixed, unemotional sequence that runs the same way for every invoice, mostly without anyone having to decide to do it. This is the escalation timeline we see working across UK trades, with the wording you can lift straight into your own templates.

Before the invoice: remove the excuses

Confirm at quote stage who pays, how, and on what terms.
Ask commercial customers for a purchase order reference before you attend.
Take a deposit on anything with significant materials.
Get the job signed off on site so there is no dispute about what was done.

Most late payments are not refusals — they are queries that nobody chased. A complete invoice with a signature and photos attached removes the majority of them before they are raised.

Day 0 — invoice and confirmation

Send the invoice the day the work is completed, with a payment link at the top. Keep the covering message warm and short:

Hi [name], thanks for having us out today. Your invoice for [job] is attached — you can pay by card using the link, or by transfer using the details on the invoice. Payment is due by [due date]. Any questions, just reply to this message.

Day 3 before due — the nudge

A reminder that lands before the due date is not chasing; it is service. It also catches the invoices that never reached the right inbox, which is the most common silent failure with commercial customers.

Hi [name], a quick reminder that invoice [number] for [amount] is due on [date]. If it needs to go to a different address or needs a PO reference adding, let me know and I will sort it today.

Day 1 overdue — the polite prompt

Same day, no drama, no accusation. Assume it was an oversight, because usually it was.

Hi [name], invoice [number] for [amount] was due yesterday and I cannot see it as received. If it has just crossed with your payment, please ignore this. Otherwise here is the payment link again: [link].

Day 7 overdue — the phone call

Email stops working around here. One short call, from a named person, asking a single question: is there anything preventing this being paid this week? You are looking for the real blocker — a missing PO, a query on a line item, a payment run that only happens on the 25th. Once you know it, you can solve it. Note the answer against the job so anyone in the office can pick it up.

In Tryoup these stages fire automatically from the invoice due date, and each reply lands on the customer's timeline next to the job, the photos and the signature. Book a demo if you would like to see the sequence running on a live account.

Day 14 overdue — the formal reminder

Now the tone changes from friendly to businesslike, and you put the consequence on the table without threatening anything you would not do.

Hi [name], invoice [number] for [amount] is now 14 days overdue. Please arrange payment by [date]. As this is a commercial account, we reserve the right to apply statutory interest and recovery costs on overdue invoices, and further work on the account will be held until the balance is cleared.

Attach a statement rather than just the invoice. Seeing the whole account at once tends to prompt action in a way a single line does not.

Day 30 overdue — decide, do not drift

Thirty days past due is a decision point, not another email. Pick one and act:

Agree a written payment plan with dates, and hold the account until it is met.
Issue a formal letter before action, giving a clear final deadline.
Pass it to a collections service or, for smaller balances, use the small claims route.
Write it off, record why, and change the terms you give that type of customer in future.

The worst outcome is none of the above: an invoice that stays open for a year, absorbing office time every month and never converting into cash.

Protecting the relationship

Consistency is what keeps good customers comfortable. When every invoice is followed by the same sequence, nobody feels singled out and nobody reads a reminder as an accusation. It also protects your team: when the system sends the first three messages, the office manager is not carrying the emotional weight of asking three times before anyone senior notices.

What to measure

Average days from job completion to invoice sent — the number you can fix fastest.
Average days from invoice to payment.
Percentage of invoices paid by the due date.
Value sitting past 30, 60 and 90 days.
Office hours per week spent chasing.

Review these monthly. If the first number is more than a day or two, start there — nothing else in the list improves while invoices are leaving late.
