Hi Suzzanne and Blake,
Given I run into the same gross up issue when processing Stripe and wage income transactions, I developed a simple Google Apps Script that I invoke from the Tiller Transaction sheet to gross up the target transaction amount (via a formula so the original data is saved) and insert a new expense row right below the original income transaction to balance out the revised up income transaction value.
It’s a work-in-progress and will require you to input your defaults via Google Script editor, but I can provide guidance via a Zoom call and/or help video. Anyway, let me know if this tool is of interest to you.
Cheers…Jim Koch
