patreon can be used for people to donate money each month to 1,5,10,15,20 up to 100 dollars per month and you give them rewards for donating like

early access
Discounts on commissions
requests
or suggestions

you can make a milestone to do a goal of how much money you make from patreon

they are also top tiers, people that donate the most money

they are tons of artists that uses this way.

Basically it's a site design to support artists, you can create various price tiers and have individual rewards for each tier level (E.G. a $5 tier for early access to art or access to uncompressed art, a $10 tier for everything in the $5 and maybe a sketch every month)

An example as such: https://www.patreon.com/PieceofSoap/posts

Obviously take into mind your work stack when coming up with patreon tiers, don't overwork yourself.

And also you may want to turn on "Charge up front" as well, https://support.patreon.com/hc/en-u.....arge-up-front- there have been some instances of people pledging at mid-month, then pulling out before the actual charge on the first of the month goes through.
