Yes. One main app is free forever. Paid plans count back-office users only; cashiers, kitchen staff and drivers are free.
How does STAK handle tax in Spain?
STAK’s tax pack keeps the rates of Spain with the date each one applies from, so every invoice is taxed at the rate in force on its date. Return data is prepared for you; filing stays with you and your adviser.
