Invoice software for import/export businesses has to start from a fact most general tools ignore: your buyers don't all pay in the same currency, and your books still need one clear answer for how much you actually billed. Quote and invoice each buyer in the currency the deal is priced in — dollars for a buyer in Chicago, euros for one in Rotterdam, baht for a domestic order — and let your dashboard consolidate every invoice back into your home currency automatically, so a quarter with deals in four currencies still totals into one number instead of four you have to add up yourself.
VAT rarely stays simple once goods start crossing a border. A single order can carry a domestic line taxed at 7% alongside an export line taxed at 0%, and getting that split wrong is how your VAT records stop matching what actually shipped. Set the rate per line item instead of per invoice, and each line — domestic or export — carries its own correct rate, with the net, VAT, and gross breakdown printed clearly regardless of which currency the invoice is in.
Cross-border deals are won and lost on more than price — terms like FOB, CIF, or a specific payment schedule need to be on the document itself, not buried in a side email a buyer's finance team never sees. Add those terms directly to your line items or notes on the quote or order confirmation, so the document a buyer signs off on already reflects exactly what was agreed, and the invoice that follows carries the same detail forward without anyone retyping it.
None of this replaces the customs paperwork that already runs alongside a shipment — Lemon Invoice covers the commercial documents: quotes, order confirmations, invoices, receipts, and credit notes, each numbered automatically and exportable in one click for your accountant. Correcting a shipment after the fact works the same way as everything else: issue a credit note against the original invoice, in the currency it was billed in, so your numbering and your currency records both stay intact even after a dispute or a partial refund.
