Late payment on invoices: reminders, escalation and the interest you can charge
An unpaid invoice is a project. The freelancers who get paid are not the ones who write angrier emails — they run a sequence, charge the interest they are entitled to, and know where their leverage is.
The invoice was correct, it was delivered on time, and now it is overdue. What separates a nuisance from a process is that a process has stages, each with a known tone and a known next step. Here is the sequence that works, and the legal leverage most people forget they have.
The reminder sequence
| Timing | Message | Assumption |
|---|---|---|
| 1–3 days after due date | Polite nudge — “flagging in case it slipped through” | Oversight. Most late invoices end here. |
| 7–10 days | Firmer restatement: invoice copy attached, due date quoted, payment link included | Still an oversight, but now documented |
| 14–21 days | Formal demand: statement of account, interest accruing, named contact | A process problem on their side |
| 30+ days | Final notice before escalation — collections, small claims or contract remedies | Dispute or cashflow failure |
The interest you are entitled to
Late-payment interest is not a threat, it is a statutory entitlement in most jurisdictions — and stating it in your terms is what makes collecting it routine:
- India: no general statutory late-payment interest for B2B supplies, but MSME suppliers registered under the MSMED Act are entitled to compound interest at three times the RBI bank rate on payments delayed beyond 45 days.
- UK: the Late Payment of Commercial Debts Act 1998 gives B2B creditors interest at 8% above the Bank of England base rate plus fixed compensation (£40–£100 per debt).
- EU: Directive 2011/7/EU entitles businesses to interest on late commercial payments without a reminder — the rate is ECB refinancing rate plus at least 8 percentage points.
- US: no federal statute; interest and fees come from your contract or state law. Put a late-fee clause (commonly 1–1.5% per month) in your terms and invoice it explicitly.
Stating the accrual in the reminder is legitimate and effective: “interest under the Late Payment of Commercial Debts Act 1998 began accruing on [date] at [rate]”. It signals that you know your rights, and it makes settlement of the principal the cheap outcome.
Where the leverage actually is
Before escalating, work out what the non-payer is protecting. A company that has stopped responding usually has one of: a disputed deliverable, a cashflow crunch being managed by seniority of debt, or an internal process failure nobody owns. Escalate to the person who signs off spend, not the person who receives email. For genuinely disputed work, a written position paper — what was agreed, what was delivered, what remains outstanding — settles more disputes than a lawyer’s letter does, at a fraction of the cost.
Prevention, briefly
- State a specific due date, not “net 30”, and put it next to the total.
- Include a payment link or UPI QR so paying takes one action.
- Invoice immediately on completion — the clock starts when you send, and most 60-day payment cycles include 20 days of internal routing before anyone sees the invoice.
- In your terms, reserve the right to charge interest and suspend work on overdue accounts.
How Invoicr helps
Invoicr tracks invoice status — sent, partial, overdue — so the follow-up list builds itself, and payment links and QR codes are printed on the invoice to remove the friction that causes most late payments. Track your invoices with an account, or start with the free builder.
Invoicr validates structure and arithmetic, not your business facts. This is general information, not tax, accounting or legal advice — check anything consequential with your accountant.
