Commercial Debt Recovery and Unpaid Invoice Guidance for Businesses Business Legal Advice Practical guidance for businesses owed money under unpaid invoices, late commercial payments and business-to-business debts.
Updated: 2026
Purpose
This guidance explains how Business Legal Advice helps businesses assess and recover unpaid commercial invoices. It covers debt assessment, pre-action letters, statutory interest, fixed late payment compensation, reasonable recovery costs, claim preparation and practical enforcement considerations.
This guidance is for general information only. It is not a full legal advice document, legal audit or opinion on any individual debt. Every debt depends on the contract, invoice, payment terms, evidence, limitation, debtor status, dispute risk and recovery prospects. Tailored advice should be booked before relying on this material for a live business decision.
Commercial Debt Recovery and Unpaid Invoice Guidance for Businesses
1. Why unpaid invoices should be assessed properly
An unpaid invoice is not just an accounting problem. It may become a legal dispute if the debtor refuses payment, raises issues about the goods or services, says the price was not agreed, alleges defects, disputes the contract, claims set-off or ignores all requests for payment.
Before action is taken, the debt should be assessed commercially and legally.
Key commercial principle
The strongest recovery position is not simply sending an aggressive letter. It is showing that the debt is legally due, properly evidenced, clearly calculated and worth pursuing.
Main debt recovery risk points
Area | What needs to be checked |
Contract | Was there an agreement for goods or services? |
Invoice | Was the invoice correctly issued and addressed? |
Payment terms | When did payment become due? |
Evidence | Are there emails, messages, quotes, delivery notes, work records or acceptance evidence? |
Dispute risk | Has the debtor complained about quality, delay, scope or price? |
Debtor status | Is the debtor still trading and likely to pay if pressured or sued? |
Limitation | Is the debt still within time? |
Proportionality | Is the likely recovery worth the cost and effort? |
2. When Business Legal Advice may agree to assist
Initial assessment
Business Legal Advice will usually review:
the invoice;
the quote, contract or order;
the payment terms;
emails, messages or proof of instruction;
proof of delivery or completion;
any complaints or disputes raised by the debtor;
the amount owed;
the age of the debt;
whether the debtor is a business;
whether statutory interest and compensation may apply;
whether the matter is suitable for pre-action recovery or claim preparation.
Practical outcome of the assessment
After assessment, Business Legal Advice may:
advise that the debt is suitable for recovery action;
request further evidence;
recommend a pre-action letter first;
recommend settlement or negotiation;
recommend claim preparation;
advise that the debt is not commercially worth pursuing;
advise that solicitor or barrister involvement may be required.
3. Business-to-business late payment rights
Where a business is owed money by another business for goods or services, it may be able to claim statutory late payment interest, fixed compensation and reasonable recovery costs.
These rights usually apply to commercial debts, not consumer debts.
Statutory interest
For qualifying business-to-business debts, statutory interest is usually calculated at:
8% above the applicable Bank of England base/reference rate
Interest is calculated daily and is simple interest, not compound interest.
Fixed compensation
A business may also claim a fixed sum for the cost of recovering a late commercial payment.
Debt amount | Fixed statutory compensation |
Up to £999.99 | £40 |
£1,000 to £9,999.99 | £70 |
£10,000 or more | £100 |
Reasonable recovery costs
Where the reasonable costs of recovering the debt exceed the fixed compensation amount, the creditor may be able to claim the additional reasonable recovery costs.
Business Legal Advice fees may therefore be included as part of the recovery calculation where they are properly incurred, proportionate and reasonable for the work required.
However, recovery of these costs is not guaranteed. The debtor may dispute them and the court may assess reasonableness.
4. How Business Legal Advice fees work
Business Legal Advice uses fixed-fee stages where possible. This keeps the recovery process clear and proportionate.
Fees are payable by the client when Business Legal Advice agrees to act. Where legally appropriate, those fees may then be added to the debt as reasonable recovery costs.
Important point
The client remains responsible for Business Legal Advice fees, court fees and any third-party fees unless otherwise agreed in writing. Where recoverable, those sums may be claimed from the debtor, but recovery depends on payment, settlement or court assessment.
5. Typical fixed-fee stages
Stage | Work included | Typical fee range |
Debt review | Review invoice, contract, payment terms, evidence, dispute risk and recovery prospects | £95–£250 |
First recovery letter | Initial formal demand, debt calculation, request for payment | £150–£250 |
Final letter before claim | Stronger pre-action letter, statutory interest, compensation and cost warning | £195–£350 |
Claim drafting support | Draft claim wording, schedule of debt, interest calculation and supporting documents | £395–£950 |
Settlement support | Review debtor response, prepare settlement wording or payment plan terms | £150–£500 |
Hearing preparation | Bundle review, witness statement support, hearing note or barrister preparation | Quoted separately |
These are guide figures only. The final fee depends on debt value, evidence, urgency, complexity, dispute risk and the level of drafting required.
6. Suggested recovery cost bands
The following table gives a practical guide to what may be claimed as statutory compensation and reasonable recovery costs where Business Legal Advice has assessed the debt and agreed to act.
These figures are not automatic. They are intended to remain commercially proportionate.
Debt amount | Fixed compensation | Suggested reasonable recovery costs for review, letters and claim drafting | Possible total recovery costs claimed |
£1,000 | £70 | £150–£250 | £220–£320 |
£2,000 | £70 | £200–£350 | £270–£420 |
£3,000 | £70 | £250–£400 | £320–£470 |
£5,000 | £70 | £350–£500 | £420–£570 |
£7,500 | £70 | £450–£700 | £520–£770 |
£10,000 | £100 | £700–£1,000 | £800–£1,100 |
£15,000 | £100 | £900–£1,400 | £1,000–£1,500 |
£20,000 | £100 | £1,100–£1,700 | £1,200–£1,800 |
£25,000 | £100 | £1,300–£2,000 | £1,400–£2,100 |
£30,000 | £100 | £1,500–£2,500 | £1,600–£2,600 |
The higher the debt, the more work may reasonably be required. However, even for larger debts, recovery costs should remain proportionate to the amount claimed and the work actually carried out.
7. Interest examples for 2026
Using a working statutory interest rate of 11.75% per year as an example:
Debt amount | Approximate yearly interest | Approximate daily interest |
£1,000 | £117.50 | £0.32 |
£2,000 | £235.00 | £0.64 |
£5,000 | £587.50 | £1.61 |
£10,000 | £1,175.00 | £3.22 |
£20,000 | £2,350.00 | £6.44 |
£30,000 | £3,525.00 | £9.66 |
Interest continues to accrue until payment, settlement or judgment, subject to the applicable rate and any contractual terms.
8. Example: £2,000 unpaid invoice
A business is owed £2,000 by another business. The invoice is overdue and no contractual interest clause applies.
Business Legal Advice reviews the invoice, emails and payment terms, and decides the debt is suitable for recovery action.
The claim may be calculated as follows:
Item | Amount |
Principal invoice debt | £2,000 |
Statutory interest | Calculated daily |
Fixed statutory compensation | £70 |
Reasonable recovery costs | Example: £250 |
Court fee | Added if a claim is issued |
Example wording:
“The principal sum outstanding is £2,000. Statutory interest is claimed under the Late Payment of Commercial Debts legislation at 8% above the applicable Bank of England reference rate, calculated daily from the date payment became overdue. Fixed compensation of £70 is also claimed. The creditor has also incurred reasonable recovery costs in assessing the debt, preparing pre-action correspondence and preparing the claim. These costs are added to the amount now sought.”
9. Example: £10,000 unpaid invoice
A business is owed £10,000 for completed services. The debtor has not raised a genuine dispute but has failed to pay after reminders.
A recovery calculation may include:
Item | Amount |
Principal invoice debt | £10,000 |
Statutory compensation | £100 |
Reasonable recovery costs | Example: £800–£1,100 |
Statutory interest | Calculated daily |
Court fee | Added if issued |
For larger debts, Business Legal Advice may recommend additional steps before issuing proceedings, including a fuller evidence review, debtor solvency check, settlement proposal, or barrister input where proportionate.
10. What the pre-action letters usually do
A properly prepared recovery letter should do more than demand money. It should make the debtor understand the legal and financial consequences of continued non-payment.
A good letter will usually:
identify the creditor and debtor;
identify the invoice and amount owed;
explain the contract or basis of liability;
state when payment became due;
refer to previous reminders or communications;
calculate interest and compensation;
add reasonable recovery costs where appropriate;
invite payment by a clear deadline;
invite any genuine dispute to be explained with evidence;
warn that a claim may be prepared if payment is not made.
11. When a claim may be prepared
If the debtor does not pay or engage properly, Business Legal Advice may assist with claim preparation. This may include:
claim summary;
particulars of claim wording;
schedule of invoices;
interest calculation;
compensation and recovery cost calculation;
evidence list;
chronology;
draft witness evidence where required;
settlement offer wording;
preparation for possible small claim or county court process.
Business Legal Advice does not guarantee that a debtor will pay and does not guarantee court outcome.
12. Important limitations
Business Legal Advice is not a firm of solicitors and does not present itself as conducting litigation as a solicitor. Work is structured as business legal support, pre-action assistance, drafting support and practical recovery guidance.
Where a case requires reserved litigation work, formal representation, complex court procedure, advocacy, urgent injunctions, insolvency action or specialist legal representation, solicitor or barrister involvement may be recommended.
Barrister involvement may be arranged for hearings or specialist advice where appropriate.
13. Debts that may not be suitable
Business Legal Advice may decline or limit involvement where:
the debtor is a consumer and different rules apply;
the debt is very old;
there is no clear invoice or contract;
the work was not completed;
there is a serious quality dispute;
the debtor is insolvent or dissolved;
the cost of recovery is disproportionate;
the client wants to pursue the debt for emotional rather than commercial reasons;
the evidence is weak or inconsistent;
the client wants to claim excessive or unsupported charges.
14. Practical checklist before booking
Before booking a debt recovery assessment, prepare:
invoice or invoices;
quote, contract, order form or written agreement;
payment terms;
proof of work, delivery or completion;
emails or messages with the debtor;
any complaint or dispute raised;
previous reminders;
debtor’s full name, business name, address and company number if available;
amount paid, amount outstanding and due date;
any agreed payment plan or admission of debt.
15. Final disclaimer
This guidance is for general information only. It is not a full legal advice document, legal audit or opinion on any individual debt. Statutory interest, compensation and recovery costs depend on the facts, contract terms, payment date, business status of the debtor, evidence, applicable law and court assessment.
aa
Business Legal Advice may assess a debt and, where appropriate, agree to provide fixed-fee recovery support. Fees may be added to the debt as reasonable recovery costs where properly recoverable, but recovery is not guaranteed.
