Sync mode note: Smart Rules run in Per-Transaction sync only. They are not available in Summary Sync (Daily Summary) on any platform. If your organization syncs in Summary mode, use Mapping / Grouping instead — it is the Summary-mode substitute for Smart Rules.

Implementing class-based expense tracking in your accounting system can be an effective way to track fees associated with various products at a granular level. This strategy involves not only tagging the sales part of a transaction but also the associated expenses. By doing so, you can track the charges incurred by your payment processor or ecommerce platform for each product category. This technique provides greater transparency over your business’s cash flow and better equips you to optimize your operations and financial strategy.
Let’s now unpack a method to achieve this by using Synder.
Using Xero? Synder creates a Bill instead of an Expense for processing fees, and Xero uses Tracking Categories instead of Classes. The steps below are the same in principle — trigger on Bill → Created instead of Expense, and choose the Tracking Category action instead of Class. See How to Automatically Assign Xero Tracking Categories Using Smart Rules for the Xero-specific setup.

Adding product names to the processing fees description
When you create a rule within Synder, you need to specify conditions that will prompt Synder to apply a specific class to an expense. However, the product name might not initially be part of the expense section of a transaction, but it can be found in the sales receipt/invoice. To fix this, please get in touch with our Support team at [email protected]. They can assist you in modifying the Expense transaction to include the product name in the ‘Description’ field. This can be done on our end solely. This is the end result that you will get in QuickBooks:
