Getting paid legally

QUESTION 01

What evidence should I collect before pursuing an unpaid service invoice?

Build a file that connects the customer’s agreement to your delivery and the unpaid balance. Keep the correct legal entity, contract or accepted proposal, purchase order if required, scope changes, delivery records, approvals, invoice, proof of submission, due-date terms and payment history together. A spreadsheet total without the underlying records is harder to explain or defend.

For an agency project, preserve the approved scope, delivery email and the client’s acceptance or specific objections. Create a short chronology and reconcile credits before sending a demand. Keep original messages and their dates; do not rewrite records after a dispute. A complete file supports discussion and professional review, but it does not by itself prove that every charge is legally owed.

QUESTION 02

Can I recover an unpaid invoice if we never signed a contract?

Possibly. A missing signature is not the same as having no evidence of an agreement, but the result depends on local law and the type of contract. Emails accepting a proposal, an authorised purchase order, part payments and evidence that the client requested and accepted the work may help establish what was agreed.

Collect the whole conversation, including price, scope, payment timing and who had authority to approve it. Separate agreed work from extras that were never approved. Do not create a backdated agreement or treat silence as automatic acceptance. For a substantial or contested balance, ask a local adviser whether the available records establish an enforceable obligation and what additional evidence is needed.

QUESTION 03

How do I word a firm payment request without making empty legal threats?

State what is unpaid, why you believe it is due, what action you need and a specific date for a reply. Give the client a clear way to identify an error or dispute. A business follow-up can be firm without claiming that a court, lawyer or collection agency is already involved.

Choose a reasonable response date for the circumstances; the example below does not create a statutory deadline. If you need a formal letter before action or another legally prescribed notice, check the applicable procedure and have it prepared or reviewed appropriately. Do not label an ordinary reminder as a court notice, invent legal consequences or threaten action you are not authorised and prepared to take.

Subject: Payment status requested — invoice [number]

Hello [name],

Our records show [currency and amount] remains outstanding on invoice [number] for [agreed service], due on [date]. The invoice and supporting delivery record are attached.

Please confirm the payment date by [reasonable reply date]. If you dispute any item or need a missing document, please identify the item, amount and reason so we can address it. If payment has already been sent, please share the remittance reference.

We will review the appropriate next step if we do not receive a response.

Thank you,
[name, role and company]

QUESTION 04

Can I add interest or a late-payment fee to a B2B invoice?

UK statutory-interest example; other countries and contracts require separate checks.

Only when the applicable contract or law supports the charge. Check the governing law, customer type, agreed terms, actual due date and calculation basis before adding anything. A fee inserted into a later reminder does not automatically become an agreed contract term.

For eligible UK business-to-business transactions, GOV.UK describes statutory interest as 8% plus the Bank of England base rate, while noting that a different contractual interest rate affects whether statutory interest can be claimed. That is a UK example, not a worldwide rate. Itemise principal, interest period and any recovery charge separately, and verify the current rules rather than copying a calculator result into every customer account.

QUESTION 05

Do US consumer debt-collection rules apply to unpaid business invoices?

United States; federal consumer-debt scope only. State and other laws can still apply.

The US Federal Trade Commission states that business debts are not covered by the federal Fair Debt Collection Practices Act. An invoice for a company’s marketing services is therefore different from a consumer credit-card or household debt. Do not copy consumer call limits or validation-notice rules and describe them as the universal standard for commercial invoices.

That exclusion does not make every collection tactic lawful. State collection laws, licensing, privacy rules, deceptive-practice restrictions and contract obligations may still matter. Establish whether the obligation is genuinely commercial, who owes it and whether you are collecting your own invoice or acting for someone else. Obtain state-specific advice before using an outside collector or automating a high-volume outreach process.

QUESTION 06

How often can I legally contact a business about an unpaid invoice?

There is no single worldwide number of permitted reminders. The relevant rules can change with the country, communication channel, debtor type and whether a third-party collector is involved. Consumer-debt limits from one jurisdiction are not a legal safe harbour for all B2B outreach.

Use one coordinated record and avoid duplicate messages from finance, the account manager and automation. Agree a next update date, contact the responsible business person during appropriate hours, and stop a scheduled sequence when a dispute or payment needs review. ASIC’s Australian guidance highlights misleading conduct and undue harassment as risks. Keep a contact log and have local advisers assess the proposed process where legal exposure is material.

QUESTION 07

Where can an Indian service business raise an eligible MSME delayed-payment claim?

India; eligibility, registration history and the buyer’s location matter.

Check eligibility before choosing the MSME route. The Ministry’s Samadhaan FAQ describes qualifying micro and small suppliers, Udyam registration and registration-timing requirements; it includes eligible service providers but excludes specified trading categories. It also identifies the relevant Micro and Small Enterprise Facilitation Council as the body acting on applications.

As checked on 22 September 2026, the official Samadhaan welcome page directs all new delayed-payment applications to the MSME ODR Portal. Follow that current official notice, assemble the agreement, invoice, delivery and payment records, and confirm your eligibility with the council or an Indian adviser. Do not assume that registering after the disputed work, holding any MSME label, or selling to an overseas company automatically qualifies the invoice.

QUESTION 08

Should I publicly name a client or contact their employees to pressure payment?

Use a private, documented escalation to people responsible for the contract and payment. Public accusations, copying unrelated employees or approaching someone’s family can create privacy, confidentiality, reputational and legal risks while doing little to resolve a genuine approval problem.

Escalate with the invoice, delivery evidence and unresolved decision: for example, ask the project sponsor and accounts-payable owner to confirm whether the dispute concerns scope or payment processing. Keep the recipient list proportionate and explain the reason for involving each person. If normal escalation fails, assess a legitimate dispute-resolution route. A late invoice is not a licence to shame someone, invent fraud allegations or disclose confidential client work.

QUESTION 09

When should a service firm consider a court claim for an unpaid invoice?

England and Wales example; use the correct procedure for the relevant jurisdiction.

Consider a claim after checking the evidence, attempting a proportionate resolution and assessing whether recovery is economically realistic. Identify the correct defendant, applicable forum, filing requirements, likely defence, fees and whether the debtor has assets. A strong invoice file does not guarantee a judgment or cash recovery.

In England and Wales, GOV.UK describes a county-court money-claim process and notes that mediation may be quicker and cheaper. Scotland and Northern Ireland use different processes. Before filing anywhere, verify local pre-action obligations, service rules and time limits; do not assume a generic demand email satisfies them. Disputed scope, cross-border parties, insolvency or a large balance are good reasons to involve a qualified local adviser early.

QUESTION 10

Can an unpaid invoice become too old to sue over?

Yes. Legal limitation periods can restrict court recovery, and the applicable period depends on jurisdiction, claim type and facts. The starting date and the effect of a later acknowledgement, part payment or insolvency can require legal analysis. Do not assume that sending another reminder resets the clock.

Record the agreement date, delivery date, original due date, every payment and any written acknowledgement. Ask a local adviser to calculate the deadline while there is still time to act. ASIC’s Australian guidance explains that limitation periods arise under state law and can vary; it also warns about misleading or harassing demands for old debts. An accounting write-off, an unpaid ledger balance and a legally enforceable claim are separate questions.
