Finance department for sole proprietors. Ready in 2 weeks.
Your own accounting system that replaces a bookkeeper, Excel and 10 third-party services. We built it for ourselves — and we issue 500+ invoices per month with almost no human input.
We use this system ourselves, every day. This isn't theory — it's our actual finance department.
Sound familiar?
If you nod at any of these — this page is for you
Excel breaks with 2+ entities
10 tabs, broken formulas, mismatched numbers, history is impossible to find.
Bookkeepers cost too much and make errors
Bookkeeping costs $200–500/mo. Mistakes surface in quarterly reports — too late.
Tools don't talk to each other
CRM here, spreadsheets there, banking somewhere else. You move data by hand.
You compile reports manually
P&L, cashflow, receivables — every report is hours in Excel and stress.
You create invoices by hand

You calculate taxes "best-effort"
Unified tax, social contributions, limits, quarterly forms — all kept in your head, dreading fines.

How we compare
FAQ
What's the tech stack?
PHP, MySQL, JavaScript, AJAX. A standard server stack that runs on any PHP-capable hosting. No exotic dependencies — easy to hand over, easy to maintain.
Where is the system hosted?
Two options: on your hosting (full control and ownership) or with us (more convenient — we handle everything). Your choice.
Who has access to the system?
Three roles: Owner — full access. Bookkeeper — finances and reports, no settings. Manager — invoices and clients, no reports. Each role sees only what's needed.
Can I use it from a phone?
Yes, fully. The system is mobile-optimized — issue invoices, view reports, manage clients right from your phone. Genuinely convenient: send an invoice in 30 seconds while waiting for coffee.
Is there a bank integration (monobank, PrivatBank)?
monobank integration is on the roadmap — we'll add it on the first project where it's needed. Current version supports importing bank statements in CSV. PrivatBank — on request.
Is there an API for integrating with other systems?
Yes, a full API. Through it AI agents can create invoices, mark payments, generate acts, email documents to clients, read reports. Connect Zapier, n8n, your CRM or our ambitiv.Assistant.
Can you migrate my Excel data?
Yes — it's part of implementation. Share your spreadsheets — we migrate clients, invoice history, balances. You keep your full history, no "starting from zero".
What about post-launch support?
First month after launch — support included. After that: on-demand, monthly, or per-project for new features. No vendor lock-in — you pay only when you actually need it.
