Updated 18 September 2026
ContApp is one of the cheapest options on the market and is built around PFAs (Romanian sole traders) and the liberal professions: invoicing plus single-entry bookkeeping, with e-Factura and an ANAF SPV connection included on every plan. Plans run from RON 19/month to RON 79/month.
BIWizz starts from a free plan, Liber — ANAF SPV sync, invoicing and the Wizzy assistant, with limits — but does not include single-entry bookkeeping. From RON 80/month (La Zi) it adds the MCP connector, and Wizzy answers about 70 questions a month about your company data.
Choose BIWizz if
- You want e-Factura and ANAF SPV at no cost: the Liber plan is free, and La Zi (RON 80/month) adds the MCP connector and higher limits.
- You want an AI assistant to talk to about your data, not just forms to fill in.
- You want to work from Claude or ChatGPT directly on your company data, through the MCP connector.
- You work with an accountant who keeps the books in SAGA and want to import directly from their database, in a shared workspace where they stop re-keying what you send over WhatsApp or email.
Choose ContApp if
- You are a PFA and need single-entry bookkeeping in the same product — BIWizz does not have that module.
- You want the receipts-and-payments register and PFA-specific records ready-made, without a separate accountant.
- You want the lowest price for invoicing with e-Factura included and have no need for an AI assistant.
- You prefer a product already proven in the PFA segment, with flows designed exactly for the liberal professions.

If you are a PFA, read the single-entry row first
This is the difference that matters most to a sole trader, and the reason ContApp can be the right choice even though it costs more to start. A PFA taxed on real income needs a receipts-and-payments register and single-entry records — ContApp has these built in, BIWizz does not.
BIWizz is designed around companies that keep double-entry books and around the accountants who serve them. If you are a PFA and want a single product covering both invoicing and your records, ContApp solves more of your problem.
Where BIWizz wins: asking questions of your company data
ContApp covers single-entry bookkeeping, which BIWizz does not. The difference lies elsewhere: BIWizz starts from a free plan with ANAF SPV sync and invoicing, and from La Zi it adds an MCP connector that lets you work from Claude or ChatGPT directly on your company data.
The second difference is how you find things out about your business. Instead of hunting for the right report, you ask: "which invoices are more than 30 days overdue", "how much VAT do I owe this month". Wizzy answers on the real data and shows its sources, and if you ask for an action — an invoice, a message to a client — it prepares it and brings it to you for approval.
On pricing, fairly
The price comparison is not quite like for like. The free Liber plan has limits (25 invoices and about 15 answers a month); to compare properly against a ContApp plan covering invoicing plus records, look at BIWizz La Zi at RON 80/month. At that level ContApp remains cheaper if all you need is invoicing and single-entry bookkeeping.
ContApp also offers annual-payment discounts, with lower equivalent monthly prices. Check their page for the current version before deciding.
