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.

Paychex Flex
