Having done this a few times, the biggest advise I can give is that time is your most valuable resource. So look to maximize this resource with each decision you make. For example, in buy vs build situations you should err on the side of buy. You can find affordable services that will handle close to 100% of your generic SaaS needs. So don't reinvent the wheel, and go with as much off-the-shelf as possible.

Absolutely! This is something I've seen many people emphasize so it is something I will keep in mind for every decision I make.

What are some examples of those services that handle close to 100% of SaaS needs?

[abiogenesis]

Three examples: Authentication, payment processing, invoices:

I would add things like sending newsletters (Mailchimp), monitoring (Sentry), various types of analytics (Segment, Hotjar) to the list.
