Use this page when you need to prepare an invoice for work billed to a client in Greece, especially B2B services where the buyer expects a full VAT invoice. The document should identify both parties, describe the supply, show the correct amounts, and give the client a clear payment instruction. A vague service note or missing tax identifier turns a simple billing step into an approval delay.
Greek invoices sit inside the EU VAT system. Greece uses VAT, ΦΠΑ, with a 24% standard rate, reduced rates of 6%, 13%, and 17%, and a 4% super-reduced rate for qualifying supplies. The applicable rate depends on the goods, services, and any special territorial rule. Use the rate that applies to the actual supply, then show the VAT rate and VAT amount clearly.
A full EU VAT invoice must include the issue date, a unique sequential invoice number, supplier and customer names and addresses, the customer VAT ID where the customer is liable for tax, a line description and quantity, the net unit price, the transaction or payment date if different, the VAT rate, the VAT amount, and a VAT breakdown by rate or exemption.
For Greece, include the supplier's VAT identification number or Greek TIN, AFM, unless a simplified invoice rule applies. A service line should name the work in plain terms, such as "Website maintenance, May 2026, 12 hours at €80 per hour." Separate taxable lines from exempt or differently rated lines so the VAT summary matches the body of the invoice.
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. That reporting layer does not replace the invoice your client reviews. It adds a transmission requirement around the invoice data, so your source fields must stay consistent.
Invoices issued through an AADE-recognized e-invoicing provider receive a Unique Entry Number after the provider transmits income documents to myDATA in real time. Those e-invoices must show a QR code for authenticity verification. Public-sector contracts also need extra attention: the staged B2G e-invoicing obligation for Greek public-sector suppliers began on September 12, 2023.
A one-off invoice works when you have a single project, a fixed fee, and clean tax details ready before billing. It is enough for occasional client work, a small consulting job, or a simple service sale where the invoice lines, VAT treatment, and payment terms do not change from month to month.
A managed workflow matters when tracked time, project rates, reimbursable costs, approvals, and client reporting feed the invoice. Everhour Reporting gives teams customizable reports with 45+ columns, grouping, filters, date ranges, and exports, so billable work can be reviewed before invoicing. Keep the Greek VAT and myDATA details in the invoice process, then use reporting to control the work that creates the charge.

A Greek invoice should show the VAT rate that applies to the specific goods or services sold. Greece's standard VAT rate is 24%, with reduced rates of 6%, 13%, and 17%, plus a 4% super-reduced rate for qualifying supplies. Do not use a reduced rate unless the supply qualifies under the applicable VAT rule.
A full VAT invoice needs the issue date, sequential invoice number, supplier and customer details, VAT identification details where required, line descriptions and quantities, net unit prices, supply or payment date if different, VAT rate, VAT amount, and a breakdown by rate or exemption. Greece-specific records should also include the supplier VAT identification number or Greek TIN, AFM.
Greek invoice data operates within AADE's myDATA environment. AADE's timologio application supports electronic invoice issuance and real-time transmission of the necessary information to myDATA. Invoices issued through an AADE-recognized e-invoicing provider receive a Unique Entry Number and must show a QR code for authenticity verification.
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, line-item, VAT, and payment details. Use language that the client can approve quickly, and keep tax identifiers and VAT breakdowns precise regardless of the invoice language.
An invoice that omits a clear payment due date creates avoidable disputes. Under EU commercial late-payment rules, if 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 receipt date is unknown. Greece's statutory commercial late-payment interest rate is 10.15% for January 1, 2026 through June 30, 2026 when no contractual rate applies.
Everhour Reporting lets teams review billable time, costs, project data, invoice status, and other work details through customizable reports with 45+ columns, grouping, filters, date ranges, and exports. A team can check the work behind an invoice before sending it through the Greek VAT and myDATA billing process.
Everhour Billing & Invoicing turns tracked billable time and expenses into client invoices from uninvoiced entries. It calculates invoice amounts from rates, time, and billable expenses while excluding non-billable work, then marks invoiced time as invoiced so the same hours do not appear again in a future invoice.
Use Everhour Reporting to review billable work, costs, invoice status, and project detail before Greek invoices go out, giving each billing cycle a clearer approval trail.
