Your payment gateway consolidates your daily transactions into one big chunk of data and you have to manually record this data in Xero's chart of accounts. As individual entries. With each entry under specific accounts. For accurate reports.
With Chargebee's integration, all you have to do is set it up once and then forget about the whole thing.
Map all the data from your payment gateway to the right categories in Xero's chart of accounts
