How do I get an invoice / e-invoice?

Your invoice for all payments is generated automatically and delivered to your registered email address. You can also download it as a PDF from your client area at any time, with access to your past invoices. For corporate users, an e-Archive or e-Invoice is issued depending on your taxpayer status.

1. Viewing and Downloading the Invoice

1. Sign in at musteri.kolan.net.tr.
2. From the top menu, go to Billing → My Invoices.
3. You'll see all your invoices in the list, with date, invoice number, amount and status (Paid / Unpaid / Cancelled).
4. Click View next to the invoice you want to see in detail.
5. On the opened screen, you can get the official document via Download PDF or Print.

2. Updating Billing Information

For the invoice to be issued correctly, your profile information must be up to date. To change your billing details:

1. Click your name at the top right of the client area and go to My Profile (Account Details).
2. Fill in the relevant fields based on your account type:
   • Individual: Name, surname, Turkish ID number, address, phone.
   • Corporate: Company title, tax office, tax number (VKN) or TCKN, address, phone.
3. Confirm the changes with Save.

3. e-Archive and e-Invoice Distinction

Invoices issued in Turkey can take two forms depending on taxpayer status:

• e-Archive Invoice: Issued for individual customers and all corporate customers who are not e-Invoice taxpayers. Delivered by email in PDF; also downloadable from the client area.
• e-Invoice: Issued for corporate customers whose turnover has exceeded the regulatory threshold and who are registered in the GIB e-Invoice system. The invoice is delivered electronically to your company's e-Invoice address through the GIB infrastructure; it can also be viewed in the client area.

The system automatically performs the taxpayer query based on the tax information in your profile and issues the appropriate invoice type. If your taxpayer status has changed, simply update the information in the client area.

4. If Your Invoice Was Issued Incorrectly

If there's an error on the invoice in fields like title, tax number, address or service detail, the invoice needs to be cancelled and reissued; don't manually correct the PDF, because the cancel+reissue process is a financial regulation requirement.

1. Open a support ticket via the client area or use the submitticket.php link.
2. Open the ticket in the Billing / Accounting category.
3. Clearly state the number of the incorrect invoice and the correct information (e.g. "tax no should be X, title should be Y").
4. Our accounting team will cancel the existing invoice and issue a new one, then send the PDF to you.

5. Didn't Receive the Invoice Email?

After your payment is confirmed, the invoice is automatically sent to your registered email address. If you think it didn't arrive:

• First check the spam / junk folder; automated send emails may sometimes be misclassified.
• Verify that the email address in your profile is correct.
• You can directly download the invoice from the My Invoices section of the client area; the email is only informational, and the actual document is in the panel.
• If you still think it hasn't reached you, open a support ticket with the invoice number; we'll resend it.

For any kind of invoice correction, cancellation, copy request or a need for a document in a different format, you can open a support ticket via the client area; our accounting team responds within a business day.
