Incoming invoices, sales & purchase books
Your whole tax bookkeeping in one place - no spreadsheets. The ledgers fill themselves from issued and received invoices, and the VAT return is computed automatically.

Sales ledger (IRA)
Built automatically from your issued invoices, split by VAT rate (25/13/5/0). Filter by period and export to CSV.
Purchase ledger (URA)
Input VAT by rate from received invoices. The basis for the VAT return, ready for your accountant, CSV export.
VAT return
Output VAT (IRA) minus input VAT (URA) = VAT due, by rate. Reminder for the filing deadline (20th of the month).

Questions & answers
Must I fiscalize from 2026?+
Yes. From 1 Jan 2026 (Fiscalization 2.0): VAT payers issue and receive B2B/B2G e-invoices, and bank-transfer orders are fiscalized too. Fiskalizator handles it automatically.
How do I issue a B2B e-invoice?+
Automatically. If the buyer has a valid OIB, Fiskalizator issues a structured e-invoice and sends it via your intermediary (Moj-eRačun or ePoslovanje).
Do I need a FINA certificate?+
For B2C fiscalization you need a certificate (FINA or Certilia, .p12); a free FINA DEMO exists for testing. Uploaded once and stored encrypted.
Does Shopify work without a developer?+
Yes. Install the app from the Shopify App Store, paste a connection code and the webhook sets itself up. No coding.
How do accountants pay?+
The accountant account is free - manage all clients from one login. Monetization is through client subscriptions, not the accountant.
How is the subscription paid?+
Shopify stores pay via Shopify. Others (WooCommerce, sole traders) pay by card (Stripe) or invoice. 14-day free trial, one-click cancel.
What if I'm not VAT-registered?+
A small taxpayer (under €60k/yr) issues invoices without VAT, with the Art. 90 VAT Act note. The status is changed in settings.
What does sending an e-invoice cost?+
The plan covers building, structuring and fiscalization; only e-invoice delivery is billed by the intermediary (~€0.08-0.25/doc). Transparent and separate.
