Pivoting my product from b2c to SaaS, how do I start?

I spent three years working in my product as a btc app for gig workers to offer their cleaning services to customers, it clearly didn’t work, I built too much, didn’t validate the idea properly, well I made every freaking mistake you can make… but I have started to think that the product I built can actually be needed by cleaning agencies, the software is quite good, comes with a backend system to manage customers, cleaners, coupon codes, it’s integrated with stripe to process payments, have a great automated invoicing system, have a mobile app for both customers and cleaners, etc.

So I don’t want to make the same mistakes again and I’d like to ask for you suggestions on how to transition to turn this into a SaaS product for cleaning agencies.

I have thought that it’s probably easier to just spin up a server in digital ocean for each agency and then configure everything there and make a copy of the mobile app and simply white label it for each agency, all of this before I really make changes to the system to make it a real multi tenanted SaaS, but again please let me know what do you think.

Thank you!!
