Pros & Cons
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.
Sage Accounting
Pros
- Payroll is bundled into every plan, so very small employers do not need a separate payroll subscription.
- Built-in Making Tax Digital VAT filing, plus CIS submissions on Standard and Plus, cover UK compliance needs.
- Monthly billing with no commitment, and introductory discounts that often run for six months.
- Reviewers praise the customisable invoices and the bank and HR integrations.
- Plus allows unlimited users, which reviewers single out.
Cons
- Reviewers report yearly price rises and say support can be slow or unhelpful.
- Users report bank-feed connection problems and occasional lag with large data sets.
- Budgeting, multi-currency and stock management are only on the top Plus tier.
- There are no employee expense claims or time tracking, and receipt capture is capped with per-receipt charges above the cap.
- Role permissions are limited, so duties cannot be cleanly separated between staff.
