This article is general information and not tax or accounting advice.
Collect the client details first
Before drafting the invoice, confirm the client legal name, billing address, country, VAT number if relevant, contact email, purchase order requirements, and agreed payment currency. EU client invoices become messy when the freelancer only has a brand name and a casual email thread. The stronger your customer record, the easier the invoice is to review.
Discuss VAT and reverse charge before sending
Many Greek freelancers working with EU business clients need to think about place of supply, reverse charge wording, VAT IDs, and supporting evidence. Those details depend on the service and customer status, so confirm the expected treatment with your accountant. Add wording only when you understand why it belongs there.
Choose currency and payment terms deliberately
Some EU clients expect EUR invoices; others work in another currency. Your invoice should make the currency, due date, payment instructions, and any bank or online payment details clear. Keep exchange-rate context where your accountant needs it, especially if your base records differ from the invoice currency.
Connect cross-border invoices to myDATA records
International work still needs organized records for Greek reporting workflows. easyTimi helps keep the customer country, tax identifiers, invoice totals, payment state, and submission context together so cross-border work does not become a separate manual process.
Make the handoff easy
At month end, group EU invoices, VAT number evidence, payment status, and any accountant questions. This keeps international billing from becoming a last-minute reconstruction exercise.
