I've started a small business. I am curious what the easiest software to use would be, or what most might be using? I have Gmail G Suite, not sure what it offers yet, maybe something in there? In previous jobs Ive just used Excel for Mac to break down each month of sales and totals, profits, and tax taken in. I also just started using Stripe for POS purchases, so I'll have various ways of accepting payments. I am leaning towards Excel, but curious to hear some options... thanks in advance.
