WISO Alternative 2026: Best Bookkeeping Tools for the Self-Employed

WISO is one of Germany's most recognised names in tax software and bookkeeping. But depending on your situation — freelancer, sole trader, or GmbH owner — WISO can quickly feel like the wrong tool for the job. This article compares the five best WISO alternatives for 2026, with honest assessments of where each one shines and where it falls short.

What is WISO and who is it designed for?

Buhl Data, the company behind WISO, actually offers two distinct products:

• WISO Steuer — Tax return software (Einkommensteuererklärung). Originally built for employees, it also supports freelancer and trade income schedules. Pricing: free (very limited) up to around €35–60 per year for the full version.

• WISO MeinBüro — Business management software for invoicing, quoting, bookkeeping, and basic tax prep. From around €12/month (basic) to €45/month (professional).

WISO Steuer works well for employed individuals with straightforward taxes. As soon as you're self-employed, run a GmbH, or have significant business expenses, the tool either becomes too complex for simple needs or too simple for complex ones. WISO MeinBüro suits small sole traders, but its desktop-heavy architecture and lack of AI automation make it feel dated compared to modern cloud tools.

Common reasons people leave WISO

• No AI-powered categorisation — bank transactions and receipts need manual sorting every month, which costs hours.

• Weak e-invoicing support — XRechnung and ZUGFeRD (mandatory for B2B in Germany from 2025) are only partially supported in WISO MeinBüro.

• Two separate products — if you need both bookkeeping (MeinBüro) and tax filing (WISO Steuer), you pay twice and manage two tools.

• Not built for GmbH/UG — corporate tax returns (Körperschaftsteuer) and proper double-entry bookkeeping for a GmbH go beyond what WISO MeinBüro handles well.

• Outdated interface — especially the desktop version, which doesn't compare well to modern cloud-native tools.

The 5 best WISO alternatives in 2026

1. Norman — AI bookkeeping for freelancers and GmbH owners

Norman is a cloud-based accounting tool built around AI automation. Connect your business bank account, and Norman automatically imports transactions, categorises them against the German chart of accounts (SKR03/SKR04), and prepares your monthly VAT advance return (UStVA). Invoicing, e-invoicing (XRechnung and ZUGFeRD), and bookkeeping are all in one place.

Pros:

• Automatic transaction categorisation — saves hours per month

• Full e-invoicing support (XRechnung, ZUGFeRD) included

• Invoicing and bookkeeping in one tool

• VAT return preparation built in

• Cloud-native, works on any device, no install needed

Cons:

• Complex GmbH year-end accounts (consolidated balance sheets, full HGB auditing) still require a tax advisor

• No direct WISO data import — switching means entering opening balances manually

Price: Invoicing and bookkeeping are completely free, with no limits. Only tax filing is paid — the Klein plan starts at €12/month.

2. Lexoffice — Germany's most popular small-business tool

Lexoffice (by Lexware) is the market leader for small businesses and freelancers in Germany. Strong bank integration, solid invoicing, and a GoBD-compliant document archive. It's particularly useful if your tax advisor uses DATEV — Lexoffice can export directly in DATEV format, which saves your accountant time (and you money on accountant fees).

Pros:

• Widely used — most accountants know how to work with Lexoffice exports

• Full double-entry bookkeeping available for GmbH

• Good invoicing and quoting features

Cons:

• Limited AI automation — significant manual booking work remains

• Mobile experience can feel clunky

• Costs rise quickly as you add features (up to €39/month)

Price: From €12/month. Direct comparison: Norman vs. Lexoffice

3. sevDesk — Invoicing-first bookkeeping

sevDesk is well known in Germany for clean, fast invoice creation and simple bookkeeping. The interface is modern and setup is quick. That said, the focus is firmly on invoicing — if you need deeper bookkeeping or tax preparation, you'll likely need additional tools or a tax advisor alongside.

Pros:

• Very easy invoice creation

• Good mobile app

• Affordable starter plan

Cons:

• Bookkeeping remains largely manual

• E-invoicing features still being built out

• Less suitable for GmbH than specialised tools

Price: From approximately €10/month. Direct comparison: Norman vs. sevDesk

4. Accountable — Mobile-first for freelancers

Accountable explicitly targets freelancers and self-employed individuals with no bookkeeping background. The app walks you through German tax concepts in plain language and helps you file your tax return step by step. Not suitable for GmbH/UG or businesses with employees.

Pros:

• Very beginner-friendly

• Supports the simplified EÜR accounting method

• Guided tax filing for freelancers

Cons:

• No GmbH support

• Limited bookkeeping depth

• Price is on the higher side for what you get

Price: From approximately €9/month. Direct comparison: Norman vs. Accountable

5. Elster — Free, but no automation

Elster is the official free tax portal run by Germany's tax authorities. It does one thing: submit tax returns. No bookkeeping, no document archive, no invoicing. If you only need to file an occasional simple tax return and have nothing else going on, Elster is fine. For day-to-day self-employed or GmbH work, it's not sufficient on its own.

Price: Free

Comparison table: WISO vs. alternatives

Best WISO alternative for freelancers and sole traders

If you're a freelancer (Freiberufler) or sole trader (Einzelunternehmer) and want bookkeeping that mostly runs itself, Norman and Lexoffice are the strongest contenders. Norman's advantage is AI categorisation — your bank account syncs automatically, transactions get assigned, and you just review. That saves significant time when you have lots of small transactions each month. Lexoffice is the better pick if your tax advisor is on DATEV and needs data in that format.

If you're a Kleinunternehmer (small business owner exempt from VAT under §19 UStG), check before signing up that the tool correctly generates invoices without German VAT — not all pricing tiers support this properly.

A full overview of German invoice requirements is on the Norman invoicing page.

Best WISO alternative for GmbH and UG owners

WISO MeinBüro hits a ceiling quickly with GmbH and UG structures: corporate income tax (Körperschaftsteuer), trade tax (Gewerbesteuer), and the mandatory HGB balance sheet are not fully covered. For GmbH owners who want to handle day-to-day bookkeeping themselves and hand polished data to a tax advisor at year-end, Norman offers the best middle ground: clean books at all times, exportable data in the format your accountant needs.

If you're considering setting up a GmbH or already have one, the Norman GmbH page gives a practical overview of what bookkeeping tasks arise and how frequently.

Which WISO alternative should you choose?

• Freelancer or sole trader who wants minimal manual work: Norman or Lexoffice

• Primarily need clean invoices, bookkeeping can wait: sevDesk

• Complete beginner with no accounting knowledge: Accountable

• GmbH owner looking for a tool that works alongside a tax advisor: Norman or Lexoffice

• Only need an annual tax return, nothing else: WISO Steuer remains fine, or use Elster for free

Switching from WISO makes the most sense when you want to reduce the hours you spend on bookkeeping while staying GoBD-compliant. All the tools above offer free trials — take them. Half an hour testing a tool tells you more than any comparison article.
