we had this ~10 years ago where I was also the aforementioned IT guy for on-offboarding, doing whatever needs to be done for marketing, to set one more TXT record, to add one more email alias, to host one more PDF file, and so on.
because this is typical when you are at the size that you have a lot of SaaS subscriptions and you need to manage them, but still way too small to have institutional muscle memory (with semi-dedicated long-hauler folks, proper enterprise accounts with good separation of concerns/controls).
That’s not a technical problem or one unique to SaaS. Someone has to be responsible for onboarding and off boarding and making sure suppliers and vendors are paid.
A lot of the HR stuff ironically can also be handled by a PEO for small businesses.
While your employer as far as hiring, firing, internal management is your actual company. As far as health benefits and payroll taxes you are “co employed” by the PEO
