Hey there!
For your Shopify store, QuickBooks is the way to go.
It connects directly with Shopify better and handles all your accounting needs - bank feeds, expense tracking, and tax prep.
Works well for most small stores according to people I know. It's straightforward to use and most accountants are already familiar with it. This is the key part. Most accountants probably are more familiar with QB.
Better than Xero or Excel in my opinion.
