I can make a backend API that spits out ML-based predictions for my clients, but user accounts, authentication, and pricing are all outside of my skill set. Is there something that can sit in between my API and clients that takes care of usage pricing, sending receipts, etc? So essentially, if I’ve got the core service, is there something that’ll help me sell it?
Maybe something like rapidapi.com?
I have come across this: https://saasify.sh/
also try the search here – https://www.indiehackers.com/search?q=saas as a service
In addition to the replies below, you can search for a SaaS starter kit (Gravity is a good one for Node/React - https://usegravity.app/). The cost may seem steep depending on which one you choose, but it'll save you a ton of time.
For User accounts & Authentication check out www.glasc.io/leza - (Easy to use low code Saas to secure your services).
Stripe + a big framework like Django / Rails / Laravel + Heroku should take you a couple of weeks to set it up.
You could also easily stich together services like firebase or Airtable with Stripe depending on your process
I've been happy using Outseta. com for this. I use it on bettersheets.co
