When I started out, I just had a printer, a Chromebook laptop, and the Amazon seller app. Believe me, I know humble beginnings. I probably wasted so much time my first few months without even having a scouting app.
Depends on your budget, if you have less than $100 dollars per week, I would get a scanner, and a subscription to Scoutly, the database is $40 a month that’s going to get you the tools to get started. If you don’t have a computer and a printer, I would get those next. But at least having a scanner and the scouting software will allow you to see if this something that works for you.
