A Greek billable-hours calculation answers three practical questions: how many approved hours are chargeable, what net fee those hours produce, and what the client sees after VAT or payment terms are applied. Greece's official currency is the euro, so local rates, net values, VAT amounts, and invoice totals are normally expressed in euros.
The calculation is contractual before it is technical. Greek invoice and myDATA requirements capture quantities, net value, VAT category, and VAT amount, but they do not prescribe a national 6-minute, 15-minute, or other billable-hour rounding increment. Your engagement letter, client policy, or profession-level convention sets the increment.
Start with approved billable hours by rate category. Multiply each category by its agreed hourly rate, add the lines, then apply VAT only after the net service value is known. For example, 18 consulting hours at €140 per hour equals €2,520, and 11 documentation hours at €95 per hour equals €1,045.
The net billable value is €3,565. For taxable professional services in Greece that do not fall under a reduced rate or exemption, the normal VAT rate is 24%, adding €855.60 and producing a gross invoice total of €4,420.60. Qualifying taxable supplies materially supplied on specified Aegean island areas can use reduced Greek VAT rates, including a 17% standard-rate equivalent.
Greek sales invoices for services supplied to entities must be issued no later than the 15th day of the month after service completion. For continuous services, the same deadline runs from the period in which remuneration becomes chargeable. A billable-hours total is not complete if it misses the invoicing date that controls when the charge is formally documented.
Payment terms also affect the billing outcome. For B2B commercial transactions in Greece, late-payment interest starts after 30 calendar days when no payment period is set. Ordinary contractual payment periods may not exceed 60 calendar days unless expressly agreed and not grossly unfair to the creditor. For January 1, 2026 through June 30, 2026, the listed statutory late-payment interest rate is 10.15%, plus €40 recovery-cost compensation per late invoice when interest is due.
A calculator is enough for a one-off estimate, a draft invoice check, or a quick review of whether the net amount, VAT amount, and gross total line up. It is also enough when one person controls the time record, the rate, the rounding increment, and the final invoice approval.
A managed workflow is the better fit when several people track time across client work, rates change by project or person, or invoices need a handoff to accounting. Everhour embeds tracking controls inside supported project tools, syncs task and project metadata, and keeps billable time connected to timesheets, budgets, and invoice workflows.

Add approved billable hours by rate category, multiply each category by its agreed hourly rate, and total the net service value. Then apply the correct VAT treatment separately. For taxable professional services in Greece, the normal VAT rate is 24% unless a reduced rate, exemption, or EU place-of-supply rule changes the treatment.
No statutory national increment applies. Greek invoice and myDATA requirements capture quantities, net value, VAT category, and VAT amount, but they do not require a national 6-minute, 15-minute, or hourly rounding rule. The rounding increment comes from the contract, client policy, or profession-level convention.
Greek VAT applies to supplies of goods and services carried out for consideration within Greece by a taxable person acting as such, unless a specific exemption or place-of-supply rule changes the treatment. Under EU place-of-supply rules, B2B services are generally taxed where the customer is established, while B2C services are generally taxed where the supplier is established.
For services supplied to entities in Greece, a sales invoice must be issued no later than the 15th day of the month after service completion. For continuous services, that same deadline runs from the period in which remuneration becomes chargeable. This deadline is separate from the arithmetic used to calculate billable hours.
The common mistake is applying VAT before the net billable value is final. First confirm approved hours, rate categories, write-downs, and rounding. Then calculate VAT on the final net service value. This order prevents the VAT amount and gross invoice total from changing after late time edits.
Everhour integrates with tools such as Asana, ClickUp, GitHub, Linear, Jira, Monday, Notion, Trello, QuickBooks, and Xero. Teams can track time inside supported workflows while project, task, estimate, and custom-field metadata sync into Everhour for billable-time review.
Connect tracked client work to project tools, billable status, and accounting handoff. Everhour keeps billable time tied to task context before the invoice leaves the workflow.
