AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Goods you sell from the UK to a buyer in Nigeria can be zero-rated for VAT, but only if they leave the UK and you hold valid evidence of supply and of export within 3 months of the time of supply (6 months where goods are processed first). HMRC VAT Notice 703, updated 4 March 2026, accepts a departure-confirmed export declaration on the Customs Declaration Service as official evidence, or commercial evidence such as an air waybill or bill of lading; if you do not have it in time, you must account for VAT at the UK rate.
Selling to Nigeria from the UK does not mean you can simply leave VAT off the invoice. Zero-rating is a relief with conditions, and HMRC can ask you to prove each one. The UK standard rate is 20% (GOV.UK VAT rates, updated 30 September 2026), so a missing document on a large consignment can turn into a real cost. This guide follows HMRC VAT Notice 703, last updated 4 March 2026.
Direct and indirect exports
Notice 703 separates two situations, and the evidence you need follows from which one you are in.
| Direct export | Indirect export | |
|---|---|---|
| Who arranges transport out of the UK | You, or a freight agent you employ | The Nigerian buyer or their agent, who collects from you in the UK |
| Typical terms | You ship by courier, post, air or sea freight | Ex-works sales |
| Evidence risk | Lower: you hold the transport documents | Higher: you rely on the buyer to send proof back |
For ex-works sales, HMRC sets a high evidence standard. Notice 703 says copies of transport documents alone will not be sufficient; the evidence must show the date and route of the movement and the mode of transport. It recommends contract terms that require the buyer to supply the export evidence, and suggests you may take a deposit equal to the VAT you would owe if the evidence never arrives.
The time limits
- 3 months from the time of supply, both to export the goods and to obtain the evidence, for direct exports and for indirect (ex-works) exports.
- 6 months where the goods are processed or incorporated into other goods before they leave.
- If the limit passes without evidence, you account for VAT at the UK rate in the VAT Return for the period in which the limit expires. If valid evidence turns up later, you can then zero-rate the supply and adjust that period.
What counts as evidence
Official evidence
An export declaration submitted on the Customs Declaration Service that has produced a departure confirmation, identified by its MRN (movement reference number) or DUCR. The business.gov.uk guidance on customs declarations adds that a declaration is needed to export to any country, that you need an EORI number even if a forwarder files it for you, and that you should keep the declaration as proof of export.
Commercial evidence
- Authenticated air waybills, sea waybills or bills of lading.
- Certificates of shipment with full consignment details.
- PIM/PIEX international consignment notes, or fully completed and signed CMR notes for road legs.
- For courier and fast parcel exports, invoices showing the unique air waybill number for each shipment. Notice 703 notes most couriers do not issue separate certificates of shipment; untracked services need more per-consignment detail linked to the customer order.
- For post: a certificate of posting such as form C&E132 or P326 stamped by the Post Office for letter post or airmail packages up to 2kg, and a fully completed customs declaration for every parcel.
What the evidence must show
Whatever the document, HMRC wants a clear audit trail from sale to export: the supplier, the consignor if different, the customer, an accurate description of the goods with quantities, a consistent value, and the destination, mode of transport and route. Contradictions between documents are what most often undermine a claim.
Why the Nigerian paperwork matters too
Your Nigerian buyer is building its own document file, and the two sets should agree. Sterling Bank's Form M guidance (modified March 2022) says a Form M is mandatory for anyone importing physical goods into Nigeria, whatever the value, and is raised against your proforma invoice. For regulated products, the Bureau Veritas SONCAP data sheet (Rev 8.4, October 2024) lists the e-Form M and the transport document among the papers needed for a SONCAP certificate. If your commercial invoice, the proforma behind the Form M and the air waybill describe the goods or value differently, both HMRC and Nigerian Customs may question the shipment. See how Form M works for UK exporters and SONCAP for UK exporters.
Worked example
Example only. A Birmingham supplier sells generator spares to a Lagos buyer for £12,000 on ex-works terms, invoiced without VAT. The buyer's forwarder collects the goods but never sends back proof of the flight. Three months after the time of supply, the supplier has no valid evidence. Notice 703 treats the amount received as VAT-inclusive, and at 20% the VAT element is one-sixth: £12,000 ÷ 6 = £2,000, which the supplier must declare. Had the contract required a £2,000 deposit refundable on receipt of evidence, the cost would have been covered.
Steps before you ship
- Decide who arranges transport. If you can, control the export yourself so the evidence is in your hands.
- Put the buyer's evidence obligation in the contract for any ex-works sale.
- Keep the CDS declaration, MRN and departure confirmation, or the courier invoice with the air waybill number.
- Check that your invoice, the buyer's proforma and the transport document use the same description, quantity and value.
- Diary the 3-month date for every supply you zero-rate.
Where Pryme fits
A Pryme Business Account can be opened from the UK and holds GBP, USD, EUR and NGN with local account details for each, so a Nigerian buyer's payment can be matched to the invoice and export file. Verifiable statements and receipts, through Pryme's partner VerifyDoc.ai, can help when you need to show that a payment was received. This is general information, not tax advice.
Questions people ask
Do I charge VAT when I sell goods to a customer in Nigeria?
Goods exported from the UK can be zero-rated if they leave the UK and you hold valid evidence of export within the time limit, usually 3 months from the time of supply, under HMRC VAT Notice 703.
Is a courier receipt enough proof of export?
Notice 703 says courier invoices showing the unique air waybill number can serve as commercial evidence. Untracked services need more information per consignment, linked to the customer order.
What if my Nigerian buyer collects the goods from my warehouse?
That is an indirect export. HMRC expects a high standard of evidence showing date, route and mode of transport; transport document copies alone are not enough. Put the buyer's duty to send evidence in the contract.
What happens if the export evidence arrives late?
You account for VAT at the UK rate when the time limit expires. If valid evidence arrives later, you can zero-rate the supply and adjust your VAT account for that period.
