A cross-border invoice is evidence for tax, accounting and commercial payment. The issuing company, customer status, place-of-supply analysis and local VAT rules must line up before the document leaves the finance system.
Which rules govern a foreign company invoice?
For EU VAT work, there is a common baseline and there are Member State rules. That split matters because a foreign company cannot treat one invoice template as a universal legal answer.
Most B2B supplies require an invoice under EU rules, while certain B2C cases and national exceptions follow their own route. Start with the transaction and the country whose invoicing rules apply, then preserve the resulting decision. Read the European Commission VAT invoicing rules.
Which VAT numbers should appear and be checked?
Use the supplier VAT number where required, collect the customer VAT number when the transaction calls for it, and document the validation performed before relying on a cross-border VAT treatment.
A VAT number identifies a taxable person registered for VAT. It is national, not an EU-wide registration. For an EU counterparty, save a dated VIES validation result alongside the contract and invoice record. The Commission explains VAT identification numbers. Validate an EU VAT number in VIES..
What must a full VAT invoice show?
A full EU VAT invoice commonly needs its issue date, a unique sequential number, both parties’ names and addresses, a supply description, pricing and the VAT treatment. Missing fields often surface during an audit or a customer onboarding review.
The applicable VAT rate and amount, or the details needed to calculate them, should be traceable. If reverse charge, exemption, self-billing or a margin scheme applies, add the relevant wording and keep the supporting analysis.
Can invoices be in English, and how long should records stay available?
English is frequently accepted in cross-border business, but language and retention requirements can be national. The safe control is to identify the governing jurisdiction before invoicing, then retain a readable invoice and the evidence behind it.
Electronic invoices are equivalent to paper invoices under the EU baseline. That does not remove local storage, accessibility, audit-trail or translation conditions. Finance teams should map these controls by registration country rather than copying a supplier’s habit.
What is a workable monthly invoice control?
Before issuing an invoice, verify customer identity, VAT status, place of supply, tax wording, currency and sequence. After issue, lock the PDF or structured record, link it to the contract and payment trail, and review exceptions each month.
This is where process ownership helps. Corpenza can support audit and compliance controls, tax-structure review, and a scoped implementation discussion.
Frequently asked questions
Does a foreign company need one VAT number for every EU country?
No. VAT numbers are national. A business supplying in several countries may need registrations in more than one country, while OSS can simplify specified consumer supplies. Confirm the supply type before choosing either path.
Is a VIES result enough on its own?
It is a useful timestamped validation control for an EU VAT number. Keep it with the commercial file, but it does not replace place-of-supply analysis, contract review or proof required for the transaction.
Can an accounting platform decide reverse charge automatically?
Software can apply a configured rule, but a human owner still needs to validate the customer type, country and service or goods treatment. Review configurations when markets or products change.
This is general information, not legal or tax advice. Rules depend on the transaction and can change.
