A Greek business invoice should identify the supplier, the customer, the transaction, and the tax treatment. Greece uses VAT, called ΦΠΑ, within the EU VAT system. For most B2B supplies, EU VAT invoicing rules generally require a VAT invoice when goods or services are supplied to another business or to a non-taxable legal entity, subject to exemptions for some financial, insurance, and other exempt transactions.
Build the invoice around the actual sale. Include the issue date, a unique sequential invoice number, supplier and customer names and addresses, the supplier VAT identification number or Greek TIN, known as AFM, and the customer VAT ID where the customer is liable for tax. Add the line description, quantity, net unit price, supply or payment date if different, VAT rate, VAT amount, and a VAT breakdown by rate or exemption.
Greece has a 24% standard VAT rate. The EU VAT-rate table also lists reduced rates of 6%, 13%, and 17%, plus a 4% super-reduced rate. The correct rate depends on the goods, services, and any special territorial rule. Put the VAT rate and VAT amount on the invoice line or in a clear summary, then separate totals by rate when more than one rate applies.
A common mistake is copying the last invoice and leaving the old VAT treatment in place. That creates cleanup for both sides when the customer posts the invoice or checks input VAT. Before sending, confirm the customer status, the supply type, the place of supply, and any exemption wording. If a transaction falls outside the normal VAT charge, the invoice should explain the treatment instead of showing an ordinary VAT amount.
Greece uses AADE's myDATA environment for invoice data transmission. AADE's timologio application supports electronic invoice issuance and real-time transmission of the necessary information to the myDATA platform. Timologio also allows document issuance language to be selected as Greek or English, which helps when the customer needs an English-language invoice but the seller still operates inside the Greek reporting environment.
Invoices issued through an AADE-recognized e-invoicing provider are transmitted to myDATA in real time, receive a Unique Entry Number, and must show a QR code for authenticity verification. Public-sector work needs extra attention. For Greek public-sector contracts, GSIS states that the staged obligation for suppliers to submit electronic invoices began on September 12, 2023, with certified e-invoicing providers and PEPPOL-related infrastructure where required.
A free invoice tool is enough when you need one client-ready invoice, already know the correct VAT treatment, and can keep the underlying records elsewhere. It works for a simple consulting invoice, a one-time service charge, or a corrected draft that needs the right fields before it goes to the customer.
A managed workflow becomes better when billable time, different rates, expenses, approvals, and repeat invoices drive the amount due. Everhour separates internal cost rates from client-facing billable rates, supports default per-person rates with per-project overrides, preserves dated rate history, and can price billable work by project, member, or task. That structure keeps invoice amounts tied to the work record instead of a copied spreadsheet.

A full EU VAT invoice for Greece needs the issue date, unique sequential invoice number, supplier and customer names and addresses, supplier VAT identification number, customer VAT ID where required, line description and quantity, net unit price, supply or payment date if different, VAT rate, VAT amount, and a VAT breakdown by rate or exemption.
Yes. AADE's timologio release notes state that document issuance language can be selected as Greek or English. The invoice still needs the required tax, party, numbering, and VAT details. Language choice does not remove myDATA or e-invoicing obligations where those rules apply to the seller or transaction.
No. Greece's standard VAT rate is 24%, but the EU VAT-rate table also lists reduced Greek rates of 6%, 13%, and 17%, plus a 4% super-reduced rate. The applicable rate depends on the goods, services, and any special territorial rule. Use the correct rate for the actual supply.
EU commercial late-payment rules use a 30 calendar day default when the contract does not fix a payment period. Interest becomes automatically payable 30 calendar days after the client receives the invoice or payment request, or after delivery if the receipt date is unknown. For Greece, the listed statutory commercial late-payment interest rate is 10.15% for January 1, 2026 through June 30, 2026.
Missing or inconsistent identifiers delay payment fastest. A customer may reject an invoice when the AFM or VAT identification number is missing, the invoice number is not sequential, the customer details do not match the contract, or the VAT rate does not match the supply. Fix those fields before sending the invoice.
Everhour separates internal cost rates from client-facing billable rates, then supports default per-person rates and per-project overrides. Rate changes can be dated, so older reports keep their original calculations while new work uses the updated rate before the invoice amount is prepared.
Everhour can generate invoices from uninvoiced billable time and expenses, then mark included time as invoiced after the invoice is created. That protects billed work from accidental reuse in a later invoice and keeps invoice status connected to project billing reports.
Use Everhour to keep dated billable rates, project overrides, and task pricing connected to the time behind each invoice, so client billing stays accurate as work changes.
