WISO Business review
Free invoicing and receipt tools, with paid WISO Steuer options for tax filing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WISO Business is Buhl Data Service GmbH’s cloud bookkeeping and invoicing product for self-employed people, freelancers, tradespeople and small businesses. Its free tier covers core invoicing and receipt work, making it a fit for solo operators who want to issue invoices and organize business records without starting with a paid subscription. It is not presented as a dedicated month-end close tool; the emphasis is on invoicing, bookkeeping and preparing EÜR data.
The permanent free plan, Gratis starten, costs €0 per year and includes unlimited classic and electronic invoices, receipt scanning with a digital archive, online payments in invoices and a real-time business overview. The €63-per-year Upgrade für WISO Steuer-Nutzer includes those features plus transfer of income and expenses into a tax return, online tax submission and a pre-check. That option is specifically for existing WISO Steuer subscription users. The €99-per-year Komplettpaket: WISO Business + WISO Steuer also includes the free-version features and tax-return transfer, submission and pre-check. Choose a paid option when the tax workflow matters; the free plan is the straightforward choice for invoicing and bookkeeping alone.
Receipt capture and payment tracking are central strengths. AI recognition identifies recipient, amount, date and tax rate; income and expenses can be categorized, and bookkeeping data can prepare EÜR data. WISO Business can process XRechnung and ZUGFeRD e-invoices, reconcile incoming payments against open invoices, provide payment links, and export invoice and receipt data for DATEV. WISO Steuer is the route for transferring bookkeeping data into tax returns. Web, iOS and Android access support cloud and mobile workflows, while GDPR is listed as a compliance feature. Freelancers needing these invoicing and tax connections may find the scope suitable; businesses seeking dedicated close management should look elsewhere.
