It's passive income in the sense that if I didn't "come in to the office" for a month, my revenue would, in all likelihood, remain the same or increase.
The entire process from on-boarding customers to them putting money in our bank account is done by computers.
1. You make a good point about languages. In fact, it seems a lot of my users are European or Latin American, so this would suit a good portion of the user base. I‘ll certainly look into adding better language support.
2. The free plan is 5,000 kB which equates to 30-100 documents (not many, I admit) assuming your PDFs are 50-150 kB. However, it is worth noting that the paid price is prorated to groups of 100 kB, each group costing only $0.01. So every document you upload outside the free plan would cost $0.005-$0.015 per month, assuming the same document sizes as I mentioned before.
One of our partners is selling our stuff for what seems to be 85% off... idk why, but if you wanna give our products a shot, check them out here (there’s no way I can personally offer a better deal lol): https://fashionsta.com/brands/men-d-skin-co.html
I also have a bunch of shares and funds that increased by some $4000 over the last year.
