eq-sync is a Chrome extension. It downloads incoming invoices from the portal, with their PDFs and an Excel list, into year-month folders, or sends them straight to your own system via API. It runs in your own session; your invoices never pass through our server.
No card needed. Request the trial from the panel with one button.
Scroll down: each step adds a layer to your archive.
You sign in to the portal as usual with ASAN İmza. eq-sync asks for no password; it works in your open session.
Pick a period. eq-sync counts the invoices and shows what is new and what changed before anything is downloaded.
One button. Approved, pending or cancelled invoices: you choose which ones go. If you chose API in the settings, each invoice is sent as JSON straight to your own system.
Each invoice PDF is named with the sender, date and serial number. Easy to find.
The month list is an xlsx file: the same columns as the portal Excel, plus a separate sheet of goods.
Everything sits in year-month folders. Next time only new and changed invoices are downloaded.
eq-sync remembers what it downloaded. The second time, only newly arrived or changed invoices are downloaded.
If an invoice’s status changes, its PDF is refreshed and marked in the list. Invoices removed from the portal are shown too.
Switch company in the portal; eq-sync tracks each tax ID separately and saves it under its own name.
The Downloads folder or any folder on your computer, for example a shared accounting folder.
If the session ends or the page reloads, it continues from where it stopped next time.
Each invoice goes straight to your address as a separate JSON request. An Idempotency-Key guards against duplicate delivery; sample data and the schema are downloadable.
Click the extension button: the panel opens on top of the portal. No other app, no other sign-in.
8:42×Choose "Send to an API" in the settings and enter the address and authentication type. eq-sync sends each invoice to your software as JSON; you build the receiving side.
in Chrome, on your computerOur server is not on this path: data goes from the browser straight to your address.
One request per invoice
New and changed invoices arrive as invoice.upsert, invoices removed from the portal as invoice.removed; at month end a month.summary for reconciliation.
The portal’s own fields
Field names are as in the portal, goods included. Personal data (passport, bank) is removed.
PDFs can be sent too
If you like, each invoice PDF goes inside the JSON as base64.
Secure authentication
https only. Bearer token, API key or Basic; credentials are stored only in the browser.
No fear of duplicates
Every request has an Idempotency-Key: if the same event arrives twice, you can ignore it.
No files in a folder
With the API option, no PDF or xlsx files are written to a folder; the folder and the API replace each other.

There is no plan to choose: every license comes with the same features. We agree together which tax IDs go on the license.
Start with a free 14-day trial covering the last 3 months, once per tax ID. Need another tax ID? We update the license; no reinstall needed.
A company archiving its own invoices and an accountant serving several companies use the same plan.
eq-sync talks to the portal from your browser, with your session. Files are written straight to your computer; they pass through no server.
