I got a job with a big cleaning company, but we were told to buy our own chemicals. I don't know where to go. I need disinfectant and maybe something else. I want to decide whether it will be profitable for me or not.

not a bad way to go about it, of course, I know that the cleaning firms themselves provide the funds. Or maybe that's how you're being vetted, I don't know. BUT you can find a couple of suppliers for this or that product. If you need a lot, it's better to look for bulk goods. I recently found just where to get disinfectant fluid https://ipax.com/

@bolded.
How much is the company paying you guys?

Do they pay per contract you execute or per month, regardless of how many contracts you execute?

If your salary is per month, what percentage of your salary would you be using to buy the chemicals, as you might have to execute a handful of jobs each month since you acknowledged that it's a big company?

What's the distance from where you reside to the company? Is it walkable, if no, how much would it cost you to get there for the week?

These are questions you need to answer before knowing if it would be profitable.
