​
How it works

​
Configure customer

Create a company and its connection that form the structure required to execute the expense sync process. Configure expense mapping preferences to associate expenses with correct accounts, suppliers, and customers.

​
Map transactions

Associate expense transactions with the correct accounts, tax rates, suppliers, and customers in your customer’s accounting software. Configure default mappings at the company level for automatic categorization.

​
Create transactions

Create expense transactions in your system and submit them to Sync2Books. Expenses are queued for sync and processed asynchronously to your customer’s accounting software.

​
Sync transactions

The sync process processes the expenses you created, maps them into the format required by the accounting software, and records them in that platform. Syncs can be triggered manually or run automatically on a schedule.

​
Upload attachments

When creating an expense transaction, allow your SMB customer to save a copy of the associated receipt in their accounting software.
