The short version

  • Only Fortnox has a free tier, so it costs nothing to try first.
  • Each has a real cost: DATEV dATEV does not publish transparent per-customer pricing the way a SaaS vendor does; your real cost is buried in your tax adviser's fee note, so comparing it against Lexware or sevdesk on price is genuinely hard.; Fortnox corporate packages alone span at least 7 named tiers (Mini through Stor+) priced from 209 kr/man to 919 kr/man, and add-on programs are billed separately per module (SEK)

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DATEV

  • DATEV does not publish transparent per-customer pricing the way a SaaS vendor does; your real cost is buried in your tax adviser's fee note, so comparing it against Lexware or sevdesk on price is genuinely hard.
  • The board has decided to wind down the Austria-specific portfolio: existing products remain usable to 31 December 2028, are free of charge during 2029, and cannot be used after 31 December 2029, so any Austrian entity on DATEV has a forced migration dated in advance.
  • It is built for German statutory practice, so a group with subsidiaries outside the DACH region will run DATEV for Germany and something else everywhere else, with a consolidation step in between.
  • Large parts of the suite are still Windows desktop software installed on a workstation or terminal server, which means IT overhead most companies no longer budget for when they think they are buying cloud accounting.
  • The lock-in is social as well as technical: because your adviser holds the installation and the history, changing accounting software usually forces you to change or retrain your adviser, which is a far bigger decision than a software migration.

Fortnox

  • Corporate packages alone span at least 7 named tiers (Mini through Stor+) priced from 209 kr/man to 919 kr/man, and add-on programs are billed separately per module (SEK)
  • The Fortnox Access verification tier is priced by transaction volume, rising from 9 kr/man at zero verifications to 199 kr/man at 1000+ verifications (SEK), so cost is not fixed and scales with usage

Answered from the vendors’ own pages

DATEV: Can I buy DATEV directly without a tax adviser?

In practice, no for most of the range. Membership of the cooperative is restricted to the tax and legal professions, and companies get access through their adviser or as a client of one.

Fortnox: Does Fortnox offer a free trial?

Yes, newly started businesses receive their first six months in Fortnox at no cost, followed by subscription-based pricing.

Source
DATEV: Is DATEV usable outside Germany?

It operates in Austria, Italy, Spain, Poland, Czechia, Slovakia and Hungary, but the depth is German. The Austrian product line is being discontinued with a hard end date of 31 December 2029.

Fortnox: What pricing tiers does Fortnox offer?

Fortnox offers tiered subscription packages that vary by module (accounting, invoicing, payroll) but specific pricing details are not listed on the main website.

Source
DATEV: What is the DATEV-Schnittstelle everyone mentions?

It is the standard export format German invoicing and ERP tools produce so bookkeeping data can be handed to a DATEV-based adviser. Supporting it is effectively a requirement to sell accounting-adjacent software in Germany.

Fortnox: How can I find Fortnox pricing information?

Detailed pricing is available on the packages page (/paket), through a purchasing guide tool at buy-guide.fortnox.se, or by contacting sales representatives directly.

Source
DATEV: Does DATEV handle e-invoicing under the German B2B mandate?

Yes, the accounting and invoicing modules were extended for the XRechnung and ZUGFeRD formats that the German B2B e-invoicing rules require.
