Frequently asked questions: Odoo Enterprise vs. Billomat
Does Odoo replace Billomat?
For pure German invoicing plus income-surplus accounting, Odoo covers the same area and goes far beyond with double-entry bookkeeping, CRM, inventory and manufacturing. Billomat remains the simpler, instantly ready solution for micro-businesses and scores with proximity to invoice financing via aifinyo.
Can I use Odoo and Billomat together?
That is rather unusual, since the invoicing functions overlap. Both offer DATEV export, so accounting can run at the tax adviser in either case. As you grow, consolidating into an ERP usually pays off rather than running both in parallel.
Does Billomat offer double-entry bookkeeping and a balance sheet?
No, Billomat is deliberately limited to the income-surplus statement and offers no double-entry bookkeeping. Anyone who needs double-entry bookkeeping and a balance sheet will find that natively in Odoo. Billomat instead relies on a lean invoicing and income-surplus focus with DATEV export.
For whom is switching to Odoo worthwhile?
The switch is worthwhile as soon as, beyond invoicing, accounting with double-entry bookkeeping, CRM, inventory, manufacturing or projects are needed. For growth and the wish for end-to-end, scalable processes, Odoo is the more suitable choice too. For an affordable entry point without ERP needs, Billomat remains sensible.
Comparing more than two systems?
This comparison puts Odoo against one competitor. If several systems are still open, a structured selection is the better route: requirements first, weighted into must, should and could, then a comparison that justifies every rating. We disclose there where we earn from a system ourselves.
