You've reached the holy grail of building a product: nearly passive income. Nearly, because again, passive income doesn't really exist. There will always be small things. But luckily, you can get other people to manage most things for you. And in turn they can get bots to manage most things for them. Only in the most extreme cases, you're alerted for issues.

The benefits of a clear mind are underestimated. Running a business is stressful. An entrepreneur's mind generally doesn't stop after work hours. New ideas, new solutions to challenges, they'll come up any time. But automation gives us a chance here to change that. Stepping away from the business when it's mature and having robots run it is one option.

Here's where many people would say: "go hire some people to work for you". Here's where I say: "avoid hiring, build robots". Hiring increasing the complexity of your product, business and life. Hiring a person means you need train and manage them and makes you liable for their income and in many countries a lot more than just that (e.g. health insurance).

You want to automate parts that take quite some time for a human, but don't take too much time to script.

Most of the regular stuff to maintain your product can be automated as a scheduled computer script (run by scheduled cron jobs on your server). Those scripts I like to call "robots". A robot for me simply means a task I used to do myself, that I wrote a script for, then scheduled to run every second, minute, hour, day or week. If you can make a script that does something and saves you from doing that task, that's a robot.

My server dashboard (called cron) is simply an app to log the result of the scheduled job. There's even services that will monitor if your scheduled cron jobs actually run.

So this is like passive income, right? No!
People would call this the magic "passive income" but I think that's a ridiculous term. You probably had to work 3 years on a crazy hardcore level to get to the point where you can automate and not work and make money. Then the question is how long will that last? Maybe another 3 years? So it's more like the first 3 years you just worked as hard as someone working 6 years normally. That's not passive income, that's just compressed income. Passive income is a myth. You can minimize work a lot, but until you sell your company, there will probably always be at least monthly situations where you need to step in.

If you've come this far with your side project, which is now a real business, it means you're near to having an autonomous organization (or Decentralized Autonomous Organizations).

I recommend if you're doing over $50,000/year revenue to pay up to $5,000 for a good accountant that understands technology, business and startups. My advice is, approach 25 different accountants and make them do a quiz. Ask them what for example Stripe is, how to do sales tax payments in different countries and how they would help manage your thousands of annual transactions.

In most countries fines are double or more of what you were supposed to pay if you didn't file properly.

Where possible, try to automate your side of the bookkeeping before it arrives at your accountant. That means, set up automated web hooks from your payment processor (like Stripe) to sync transactions automatically to
a Google spreadsheet or database. Don't forget to also sync stuff like refunds. For expenses, you'll want to save every single invoice you pay to a Dropbox folder with the filename format:
./Expenses/YYYY-MM-DD - Company -
Description - USD x,xxx.PDF

Try to limit your income and expenses to as few mediums as possible to make your bookkeeping more simple. I only get money via Stripe now and I spend it via PayPal or my business bank account card. That means I only need to dump 3 data sources to get 100% coverage of my transactions.
