Your customers can't reach checkout without entering their TC ID (Individual) or tax details (Corporate) on the cart page. Details are validated, written to the order note - ready for e-invoicing. No Shopify Plus required.
A 1-minute intro - from setup to your first invoice.
The facts a merchant asks first, in one place.
Sepette Fatura no longer just collects invoice details. Connect your account and the order lands on the app's invoice screen; e-Arşiv or e-Fatura is issued in one click and you download the PDF right there. All three providers are live today.
Trendyol's e-Faturam (Digital Planet) infrastructure. You connect with your portal e-mail and password; the password is stored encrypted and never shown again. Issued invoices land in your e-Faturam archive.

You connect your Paraşüt account from its own authorisation screen - you never type your password into the app. Contacts and products are created on the Paraşüt side, so the invoice sits with the rest of your bookkeeping.
One-step authorisation with your Logo İşbaşı account; again, no password is entered into the app. Invoices land in your İşbaşı ledger and your bookkeeping flow stays intact.
Sepette Fatura runs on Shopify's Theme App Extension framework. The widget you add to the cart page keeps the checkout button disabled until your customer enters their invoice details - no code, right from the theme editor.
Install from the Shopify App Store and pick your plan. Every plan starts with a 7-day free trial - you're not charged until it ends.
Set up Individual / Corporate tabs, required fields and colors. Add the “Sepette Fatura” block to the cart page from the theme editor.
On the cart page the customer enters their details (TC/tax number validated) and proceeds to checkout. The info is written to the order note - you issue the e-invoice.
From the invoice form to the order screen - how Sepette Fatura looks in your store.
Built for Shopify merchants in Türkiye. Works even without checkout editing access (Shopify Plus).
Two tabs: TC ID for individuals; company title, tax office and tax number for businesses. You choose which fields are required.
TC ID (11 digits) and tax number (10 digits) are validated with an algorithmic checksum. Invalid numbers can't proceed to checkout.
The native checkout button stays disabled until the form is filled. Cart drawer and express checkout are redirected to the invoice form too.
You add the widget to the cart page from the theme editor. Fully responsive, no developer needed. Width and colors are adjustable.
Invoice details are written to the order notes (cart attributes) and appear under “Additional details” in the Shopify order.
An embedded panel inside Shopify admin. No third-party scripts, doesn't break the checkout flow, doesn't affect store speed.
