Accounting for Import / Export & Trading: Bookkeeping Across Borders

Trading internationally adds a layer of complexity most domestic businesses never have to deal with: multiple currencies, customs processes, and VAT rules that change depending on where your goods and customers are. None of it is unmanageable, but it does need bookkeeping that's built for it from the start rather than adapted after something goes wrong.

Multi-currency bookkeeping and FX

If you buy or sell in currencies other than sterling, the exchange rate on the day you invoice, the day you're paid, and the day you convert the money back to GBP can all be different, and each of those movements needs to be recorded correctly, not just netted off as a vague "bank charges" line. Left unmanaged, FX movements can meaningfully distort your reported profit, making a good trading month look weak or a genuinely weak month look fine, purely because of currency timing rather than the underlying business.

EORI numbers and customs declarations

To import or export goods between the UK and most other countries, your business generally needs an Economic Operators Registration and Identification (EORI) number, and consignments need to be declared through HMRC's Customs Declaration Service, usually via a freight forwarder or customs agent on your behalf. Getting your commodity codes and customs valuations right matters for more than compliance: they directly determine how much duty you pay, and errors here tend to surface as unexpected costs well after the goods have already moved.

Import VAT and postponed VAT accounting

Import VAT is due on goods brought into the UK, but most VAT-registered businesses can use postponed VAT accounting, meaning you declare and reclaim the import VAT on the same VAT return rather than paying it upfront at the border and waiting to reclaim it. This makes a real difference to cash flow for businesses importing regularly, but it needs to be set up and reconciled correctly against your customs records and monthly postponed VAT statements. A mismatch here is one of the more common reasons import VAT reclaims get queried.

Rules of origin and duty

Where your goods actually originate, not just where they were last shipped from, can determine whether preferential duty rates apply under trade agreements, or whether standard rates kick in instead. This is easy to get wrong when supply chains involve components or processing from more than one country, and it's worth having someone check the detail rather than assuming a rate applies because it did on a previous shipment.

Multi-jurisdiction VAT and sales tax

If you sell into other countries directly, rather than exporting to a distributor, you may need to register for VAT or sales tax in those jurisdictions too, depending on local thresholds and rules, which vary considerably by country. Bookkeeping needs to track sales by destination clearly enough to flag when you're approaching a registration threshold somewhere new, rather than finding out after the fact.

Supplier and customer payment terms across borders

International trade often comes with longer payment terms, letters of credit, or upfront deposits, all of which affect cash flow differently to a typical domestic invoice. Forecasting that accounts for these terms, and for the currency risk sitting inside them, gives a much more realistic picture of when money will actually be available than assuming payment terms work the same way they would with a UK customer.

How Books & Returns helps

We handle cross-border transaction bookkeeping, multi-currency reporting, and VAT across import, export and multi-jurisdiction sales, working alongside your customs agent or freight forwarder rather than duplicating their work. One fixed fee, clear reporting on what's actually happening across your currencies and borders, and a named contact who won't need the basics re-explained every time you call.
