@notary.farley You’re Absolutely Spot-On with your astute assessment.
This is the reason I often express that Professional Signing Agents [PSAs] should create a Schedule of Fees (or a calculating spreadsheet like yours).
For any Notary Cafe members who haven’t yet been able to create a Schedule of Fees for the professional services you provide, please reference this thread (see direct Notary Cafe url below) as it will Guide you through the process.
