@JenoP I have a similar situation with fees taken out by Shopify.

I have a Sales Receipt created by Cloud Cart Connector (Imports Shopify sales to Quickbooks) and I have a transaction imported from my bank in the "for review" state.

I want to match the Sales Receipt to the imported bank record, however the Sales Receipt is for an amount ($15.41) higher than the bank transaction  ($14.66 (Sales Receipt - Shopify fee)).  The Quickbooks Online match interface for the bank transaction will not show any Sales Receipts for amounts greater than the bank transaction amount. I'm at a loss as to how to properly match the Sales Receipt and associated bank transaction while appropriately accruing the fees.

FWIW... I've contacted Quickbooks customer support and they told me they don't have a solution for me and just told me to submit feedback in hopes of future enhancements. 😕

This doesn't exactly help me get my books in order for tax time.  Any suggestions?
