 ### Pending questions / unknowns
-- Does Trial Balance Report work for what they need for manual entry into QB?
-- Is there an existing report for what they need for their sales tax calculations, or do we need to make one? How are they doing these calculations now?
-  - If we did it ourself, it would be looking at all payment entries for period, finding out how much is tax by referencing the attached invoice, then calculating that final number.
-- Can we use tax rules to apply taxes per-customer, or do we want to add custom logic to select the correct sales tax template based on the customer's zip code?
-- Who needs access to Sales Invoice, who creates the invoices? Is the same group of people the ones that send out the Payment Request?
 - Who needs access to Payment Entry directly, which would mainly be used for entering cash and checks? How does the current ERPNext flow for entering cash/checks work for them when the customer pays more than they owe, thus resulting in a credit on the account?
