How to Deal with Late Payers (Without Ruining the Client Relationship)
You’ve done the work. The client was thrilled. You sent the invoice. And now... crickets.
Dealing with late payments is the most universally hated part of running a small business in the UK. Research shows that a staggering amount of small business invoices are paid late, tying up cash flow and causing unnecessary sleepless nights.
The hardest part? The awkwardness. You want to get paid, but you also don't want to ruin the relationship with a client who might give you more work in the future.
Here at Zippy Invoices, we believe getting paid shouldn't feel like begging. Here is our step-by-step, no-nonsense guide to chasing late payments professionally, legally, and effectively—complete with email templates you can copy and paste today.
The Mindset Shift: It’s Business, Not Personal
Before you send a single email, you need to change your mindset. Chasing an invoice is not rude. You have fulfilled your end of a legal contract; they have not.
Most of the time, the client isn't maliciously withholding your money. They are busy, their inbox is a mess, or their accounts department only does payment runs on a specific Tuesday. Be professional, be polite, but be persistent.
Step 1: The Friendly Nudge (1-3 Days Overdue)
Assume positive intent. The goal here is a gentle tap on the shoulder. Keep it light, friendly, and helpful by re-attaching the original invoice.
Subject: Following up: Invoice [Invoice Number] for [Project Name]
Hi [Client Name],
I hope you’re having a great week!
I’m just sending a quick note to check that you received Invoice [Invoice Number] for £[Amount], which was due on [Due Date]?
I’ve attached another copy here just in case it got lost in the email shuffle. If it’s already been passed to your accounts team for processing, please feel free to ignore this!
Best wishes,
[Your Name]
Step 2: The Firm Reminder (7-14 Days Overdue)
The grace period is over. They know they owe you. The tone shifts from "Did you see this?" to "When will this be paid?"
Subject: OVERDUE: Invoice [Invoice Number]
Hi [Client Name],
I am writing to remind you that Invoice [Invoice Number] for the amount of £[Amount] is now [Number] days overdue.
Could you please let me know the status of this payment and when I can expect the funds to clear into my account?
I have attached the invoice again for your reference, which includes my bank details at the bottom.
I look forward to hearing from you shortly so we can get this squared away.
Regards,
[Your Name]
Step 3: The Final Notice & The Law (30+ Days Overdue)
If a business-to-business (B2B) client is ignoring your emails after 30 days, you need to pull out the heavy artillery.
Under UK law (The Late Payment of Commercial Debts Act), if another business pays you late, you have the legal right to charge:
Statutory Interest: 8% plus the Bank of England base rate.
Fixed Debt Recovery Costs: Between £40 and £100 per invoice, depending on the debt size.
You don't have to charge this, but simply mentioning that you can usually gets the invoice paid immediately.
Subject: FINAL NOTICE: Overdue Invoice [Invoice Number]
Dear [Client Name],
This is a final reminder that Invoice [Invoice Number] for £[Amount] is now significantly overdue.
Please be aware that under the Late Payment of Commercial Debts (Interest) Act 1998, I am legally entitled to charge statutory interest at 8% plus the Bank of England base rate, as well as fixed debt recovery costs, on late commercial payments.
I would strongly prefer not to add these late fees to your account or escalate this to a debt collection agency.
Please ensure the full amount of £[Amount] is transferred to my account by [Date - usually 48 hours from now] to avoid further action.
Sincerely,
[Your Name]

The Ultimate Fix: Prevention
The absolute best way to deal with late payers is to stop it happening in the first place.
Stop offering 30-day terms. Unless you are dealing with massive corporations, make your terms 7 days or 14 days.
Take a deposit. Never fund a client's project out of your own pocket. Get 50% upfront.
Invoice immediately. Don't wait for "Admin Friday." The faster you invoice, the faster you get paid.
This is exactly why we built Zippy Invoices. With Zippy, you can generate a crisp, professional, legally compliant UK invoice from your phone while you're still sitting in the van or leaving the client's office. Hit send immediately, and keep your cash flow moving.
