Pros & Cons
AADDISON
Pros
- Covers German compliance in depth, including GoBD-oriented immutable records, ELSTER E-Bilanz filing, and ZUGFeRD and XRechnung e-invoice processing.
- Combines financial accounting, cost accounting, fixed assets, payroll and controlling in one suite, so data is entered once.
- Converts DATEV batch and journal data in both directions, which helps firms that work with DATEV-using partners.
- You can install it on your own servers or run it in the ADDISON Business Cloud on German data centers.
- A large installed base of about 14,000 installations, plus a hotline included in the price.
Cons
- No public pricing, so buyers must request a quote.
- No publicly documented REST API. Integration relies mostly on file exchange, partner connectors or middleware.
- Some connectors and export tools need separate licenses, which can add unplanned costs.
- It is built around German tax law, which limits its use outside the DACH region.
- Very few public user reviews; OMR lists only one.
Fortnox
Pros
- More than 500 integrations, and one 189 kr licence covers all of them.
- A single platform covers bookkeeping, invoicing, payroll, supplier invoice approval, payments and a company card, which suits Swedish SMEs.
- Accounting firms get a dedicated bureau package for working in their clients' books.
- New companies get six months free, and every new subscription has a 30-day open purchase period.
- Trustpilot and Shopify app reviewers frequently praise customer service and sync reliability.
Cons
- Usage fees for invoices, paid employees and interpretations, plus an Access fee that scales with activity, make total cost hard to predict.
- Three-month agreements cost 15 percent more than the 12-month list prices.
- The product is Swedish-focused, and users have asked for an English interface.
- Some users call the reporting tools dated and say neobank integrations such as Revolut are missing.
