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.

Polar

  • Percentage-based fees higher than some specialized processors for high-volume transactions
  • Merchant of record model may not suit companies preferring direct payment control
  • Free Starter tier limited with 5% fees reducing appeal for production use
  • Setup and integration effort required despite API simplicity

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.

Polar: Do you handle international payments and taxes?

Yes, Polar acts as merchant of record in 100+ markets, handling payment processing, tax collection, and compliance automatically.

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.

Polar: Is there a free tier?

Yes, the Starter plan is free and charges 5% + $0.50 per transaction, ideal for testing and early-stage development.

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.

Polar: Do you offer discounts for startups?

Yes, the Startup Program provides the Scale plan free for 12 months for early-stage AI companies.

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