What it keeps

Accounts

Customers and suppliers with a running balance, aging of what is overdue, and a statement you can send as a PDF. Payments settle the oldest debt first.

Invoices

Sales and purchase invoices, quotes and delivery notes with VAT and discounts worked out for you. Turn a quote into an invoice; cancel with a reason instead of deleting.

Stock and cash

Products and services, stock that moves with every invoice, a low-stock list, and income and expenses by category.

GİB, if you want it

Send e-Archive invoices from the app to GİB's own portal with your user code and sign them with the SMS code. Sync shows what GİB actually has.

Works without signal

Every screen works offline. Nothing waits on a server, because there isn't one.

Yours to take

A single backup file, optionally password protected, and CSV exports. Move to a new phone or hand the files to your accountant.

Free

No subscription, no credits, no ads.
