A Turkey invoice email is for sending a completed invoice document to a Turkish buyer without losing the tax and recordkeeping details that belong on the invoice itself. The attachment or e-document must show the commercial transaction clearly, including the seller, buyer, line items, tax treatment, issue date, and document number.
Turkey uses VAT, called KDV. The general VAT rate is 20%, with reduced rates of 1% for List No. I supplies and 10% for List No. II supplies such as basic foodstuffs, textiles, books, and similar publications. Use the rate that matches the supply, then show the tax type, rate, and amount on the invoice.
Turkish e-Fatura and e-Arşiv invoices must include the issue date and document number, seller name or trade name, address, tax office and tax ID, buyer name or trade name and tax ID where applicable, goods or work description, quantity, price, amount, tax type, rate and amount, and delivery date and dispatch note number for goods.
Invoices identify taxpayers with VKN/TCKN and the registered tax office for the seller and applicable buyers. Turkish e-documents also use a document number made of a three-character unit code and a 13-digit sequence. The sequence includes a four-character year and a nine-character serial number that starts from 1 each year and cannot be reused by the taxpayer.
Emailing a PDF works only after you confirm the invoice type the transaction requires. When both seller and buyer are registered e-Fatura users, invoices between them must be issued and received as e-Fatura except for stated exceptions. The email can support delivery, but it does not replace the e-Fatura process for those registered users.
As of 2026, invoices issued by taxpayers not already in e-Arşiv generally must be issued as e-Arşiv through the Revenue Administration portal or an approved private integrator regardless of amount. Taxpayers taxed under simple or operating-account rules have a TRY 3,000 threshold through 2026 and move to no-threshold treatment from 2027.
A one-off email invoice tool is enough for a single document, especially when you already know the buyer details, KDV rate, invoice type, and delivery record. It keeps the task focused: prepare the invoice, attach the correct document, write a concise payment note, and keep a copy with the related correspondence.
A managed workflow becomes necessary when billable work changes by project, task, or person. Everhour supports project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports for billable time, non-billable time, billable amount, and cost, so invoice totals come from tracked work instead of manual reconstruction.

A Turkey invoice can be emailed as a delivery method, but the invoice type still controls compliance. Registered e-Fatura users must issue and receive e-Fatura between each other except for stated exceptions. Other taxpayers may need e-Arşiv through the Revenue Administration portal or an approved private integrator before emailing the customer copy.
A Turkish invoice should show KDV as the tax type, the correct KDV rate, and the KDV amount. It should also identify the seller with name or trade name, address, registered tax office, and VKN/TCKN. Buyer tax details belong on the invoice where applicable, especially for business customers.
The Turkish e-document number has a required structure. It uses a three-character unit code plus a 13-digit sequence. That sequence includes a four-character year and a nine-character serial number that starts from 1 at the beginning of each year and cannot be reused by the taxpayer.
For internet sales, e-Arşiv invoices must state that the sale was made online and include the website address, payment method, payment date, carrier name and VKN/TCKN for goods shipments, the shipment or service performance date, and return-section details for returned goods. Omitting those fields weakens the invoice record.
Payment terms are primarily a commercial term for Turkey invoices, not a separate invoice-format mandate in the listed facts. Put the due date, bank details, and payment reference in the invoice email and document so the buyer knows exactly how and when to pay.
Everhour lets admins set project billing status, mark specific tasks as non-billable, use custom task rates, and apply member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so invoice preparation starts from classified work records.
Everhour turns tracked billable time and expenses into client invoices, calculates amounts from rates and billable expenses, and excludes non-billable work. Invoices can be exported to QuickBooks Online, Xero, or FreshBooks as drafts for accounting follow-up.
Classify billable work before invoice prep. Everhour keeps project billing status, task exceptions, custom rates, and billable reports connected, so Turkish invoice emails start from cleaner billing records.
