Partial Payments (and Tax Effects)
Currently, there is no way to apply a payment to a specific line on the applicable invoice. This creates an issue with both revenue accounts and sales tax liabilities. For example, we have invoices with both taxable and non-taxable items. When a customer pays for just the taxable item, the system pro-rates that payment across all of the items on the invoice. So, if we invoice for $1,000 of taxable dues [Dues A] with taxes of $100 and then a separate non-taxable item of $200 [Dues B], when they pay for Dues A with $1,100, it is recognizing revenue for Dues A, Dues B and recognizing sales tax of less than $100 even though we have collected and need to remit the full $100.
Being able to apply a payment to specific line items would be a nice feature to see in the future.
