Ecommerce accounting in Xero and A2X for two small businesses

Hi - I am currently overpaying an accountant to keep the books and reports for two of my Amazon-based businesses. We have been running in Xero for over a year now. The current accountant spends about 1.5 hours per business each month and then more at the end of the year to help with inventory rationalization. I am currently getting no help with tax filing but welcome it if it is part of what you can do.

Please share your credentials and experience with working with ecommerce businesses selling globally on Amazon. Thank you.
