Every payout has a story.
eComSum will show the workings.

A marketplace deposit can include sales, fees, refunds, reserves and adjustments from different reporting periods. eComSum will bring those moving parts together and keep the original records close to every figure.

That means clearer month-end books, quicker questions for your accountant and a review trail you can follow from the headline number all the way back to its source.
