WISO Business

WISO Business is cloud software for invoicing, receipts and business bookkeeping, best suited to small businesses that want a free way to manage routine records. Its clearest advantage is pairing that free core with paid options for moving income and expenses into a WISO tax return.

Overview

The product combines invoicing and receipt management with reconciliation automation and an audit trail. The free plan is unusually useful for ongoing invoice work because it includes unlimited classic and electronic invoices; the paid plans are chiefly for users who need tax-return transfer and online submission.

Key features

Invoices and records

Users can scan receipts, keep them in a digital archive, include online payments in invoices and view business activity in real time. Together, these functions cover a practical small-business recordkeeping workflow without a free-plan invoice quota. Reconciliation automation can reduce manual matching, while an audit trail supports traceability.

Tax workflow

Both paid plans add the ability to transfer income and expenses into a tax return, submit taxes online and run a pre-check. That is a focused extension of the free invoicing and records tool, rather than a broader set of paid capabilities. It is most relevant to businesses already using WISO Steuer.

Pricing

The free plan is the strongest choice if invoicing and receipt organization are the priority. At €63 a year, the upgrade adds the stated tax workflow; the €99 a year package describes the same tax-related functions alongside WISO Business and WISO Steuer. The feature descriptions do not distinguish those two paid tiers beyond the package name, so the lower-priced upgrade is the clearer fit when the combined package is not needed.

Platforms

WISO Business runs on the web and has Android and iOS apps. Cloud deployment suits users who want access across those platforms.

Who it's for

Choose WISO Business if you run a small business, need invoice and receipt tools, and value an uncapped invoice allowance on a permanently free plan. The paid options make more sense when you want income and expenses transferred into a tax return and online tax submission. It is less suited to someone looking for a distinct set of expanded paid bookkeeping features: the paid tiers share the same stated tax workflow.

Pros and cons

• Pros: Unlimited classic and electronic invoices on a permanently free plan, with receipt scanning and a digital archive included.
• Pros: Online payments in invoices and a real-time business overview bring useful transaction and activity functions into the free tier.
• Pros: Reconciliation automation and an audit trail add bookkeeping controls beyond invoice creation.
• Cons: The tax-return transfer, online submission and pre-check require a paid plan.
• Cons: Both paid tiers state the same tax features, making the distinction between the 63.00 EUR and 99.00 EUR annual options difficult to assess from their feature sets alone.

Alternatives

Compare accounting automation software if you want to assess a broader category of tools.

• Docyt is worth considering if you want its free Accountant Copilot plan, which includes AI categorization, bank and card reconciliation, and month-end close automation.
• AccelClose may suit teams focused on close work: its free plan covers up to 100 records and one entity, with manual journal entries and Excel/CSV export.
• FINSYNC offers free funding-readiness support through its Funding Navigator, a different starting point for businesses seeking funding connections.
• CloseZero is an alternative with a free plan for businesses under $10,000 MRR or $100,000 raised, including AI bookkeeping and invoicing.
• Arvexi is another option to compare.
• Concourse is another freemium web option.
• FinBoard Month-End Close uses custom pricing and may be relevant if you want a quote structured around entities, modules, close cadence and team seats.
• Finlens offers an AI Accounting plan at $49 a month, with up to $100k/month in expenses, up to three bank accounts and unlimited users; consider it if those stated limits and features better match your operation.

Verdict

WISO Business is a strong fit for small businesses that need invoices and receipt records without a recurring cost, especially when unlimited invoicing matters. Choose a paid tier when the WISO tax workflow is the reason to pay; look elsewhere if you need a clearly differentiated paid feature set beyond tax transfer and submission.
