How pricing works
OSOWA is priced per module. The industry a company operates in decides which modules it switches on, and it pays for those modules only, not for a fixed bundle it never fully opens. A subscription starts at 197 euro per month. Three bundles exist for companies that use most of what is in them: Essentials 197 euro, Growth 397 euro and Enterprise 897 euro per month, excluding VAT. An annual agreement is ten monthly payments for twelve months. Because every module sits in the same system, OSOWA ranks the best next action for each user every day.
Which modules each industry switches on
Hospitality, real estate, construction, retail, clinics and practices, professional services, and events each switch on their own OSOWA modules. Every module and every price is listed on
the modules page
and
the pricing page
, and each industry has its own page under
industries
