@Mike MakkarI had the same desire to have everything in one place for tracking. Since I use QuickBooks for bookkeeping, I had planned to use QuickBooks Payments / Merchant Services for electronic rent collection. However, after signing up and going around and around with their tech help, it turns out that QuickBooks Payments doesn't work for QuickBooks for Mac! (Well, I can manually accept a credit card payment, but I can't send recurring invoices and accept ACH payments, which is what we really need.) They told me I could switch to QuickBooks Online which has email invoicing. But the QB Online version with class tracking costs $40/month, and I had just paid $200 for QuickBooks for Mac, which they told me would do what I needed! I can't imagine paying $480/year just to add electronic invoicing.
So, long story short, I decided to use Cozy for rent payments. Wow, what a slick and simple setup! Totally different experience than QuickBooks. And my tenants already have Cozy accounts since we used them for the background/credit checks, so it's an easy and natural transition. Nice!
