I'm looking for some examples of products offered both as SaaS and a self-hosted option. Is one-time payment the common method? Does the price should depend on a size of a company?
I'll throw Atlassian's products into the mix. I've personally only used their SaaS versions, but believe they charge on a recurring basis in several tiers by number of seats in both cases.
Activecollab has saas vs self-hosted.
Thanks for the example. I expected a higher price for the self-hosted version: it's only 3 months worth of the highest saas plan.
Fairly limited support, charge for install/upgrade assistance, and no need to worry about hosting/resources/scaling. They can still charge a fee in a year for license to new upgrades.
Not sure if it matches your criteria. But the only thing I could think of would be OpenStack
Isn't OpenStack just an open source project? Ie. it doesn't sell anything.
Correct, I misunderstood the question. I thought OP was asking for examples where you could purchase a SAAS service or choose to have it self hosted.
