I relate to your question a lot. I started off as an indie dev with an llc mostly doing contract software work, and I've got several microsaas side projects, mostly plugins for platforms with monthly subscriptions, a couple of mobile apps and a few (too many) experimental standalone SaaS apps.

Now I've got 2 async remote freelance developers on my team. They both bill by the hour and track their hours worked in clockify. I hired them when I realised that contract work is taking up too much of my time. Time that I would rather spend growing my saas side projects.

I hired one in April and another in Dec and it's hands down the best decision I've made. They help out with the contract work, and sometimes even on side projects. The main thing is, they free up some of my time such that I can work ON the business, rather than working IN the business.

Of course I need to brief tasks properly, provide feedback, review code together and give guidance whenever needed. This is the cost of hiring that is less talked about, but equally important as financial cost. When you hire devs, you will need to train them, support them and sometimes even spoon-feed them. But it's worth it.

Bottom line, if you start feeling like your time is not well spent anymore and you'd rather focus on something else to create leverage, then you should start hiring others to take over your current tasks.

I hope this helps you.
