Frequently Asked QuestionsFAQ

BauFin is comprehensive business software built specifically for craftsmen and construction companies. Invoices, quotes, orders, time tracking, trip log, cash book, subcontractor management, four portals (customer, accountant, subcontractor and employee), planning tools and accounting — all in one system, in seven languages (DE/PL/EN/RO/TR/HR/UK).

For sole proprietors (Einzelunternehmer) and partnerships (GbR) in construction — tilers, masons, painters, roofers, electricians and all other craftsmen. BauFin uses EÜR (simplified accounting) used by most craft businesses.

Yes. BauFin offers a free trial period. No credit card required. Just register and get started.

Seven languages — German, Polish, English, Romanian, Turkish, Croatian, Ukrainian. Completely — menus, forms, help texts and emails. The documents for your client, tax adviser and the tax office are produced in German, exactly as German business practice requires. You work in your language, while the paperwork going out is German. Especially practical for multilingual teams on German construction sites.

No. BauFin prepares all data so your tax advisor can use it directly (DATEV export, EÜR, document archive). You save time and money — your advisor gets clean data instead of a box of receipts.

BauFin supports immutable storage, continuous numbering, audit trail, procedural documentation and 10-year archiving with SHA-256 checksums. Whether usage meets GoBD requirements also depends on setup, working process and procedural documentation.

BauFin can prepare §13b UStG hints based on customer data and markers and place the wording "Steuerschuldnerschaft des Leistungsempfängers" on the invoice. The tax classification must be checked by the user or tax advisor.

If no valid exemption certificate (§48b EStG) is stored for the subcontractor, BauFin can prepare the 15% construction withholding tax calculation and documents for review and filing.

Yes. You can activate the small business regulation in settings. Invoices will be created without VAT with the legally required notice.

Yes. BauFin supports creating ZUGFeRD PDF/A-3 with embedded XML and XRechnung for public clients. Formal invoice validation remains part of your process.
