Ability to split excess payment between income line items

Ability to split excess payment between income line items

Hello,

As a service business sometimes our customers "round up" their payment as appreciation for work completed. For example, amount invoiced is $190 and customer pays $200. They do not want or expect this excess amount to be applied to a future invoice, rather they intend it to be a "tip" for good service. In our previous accounting program we could easily split this payment, applying $190 to the invoice and the $10 "tip" to another income line item, which kept both our bank reconciliation and our accounts receivable/customer statements accurate. With Zoho this doesn't seem possible; the excess can only be stored as a customer credit for future use, and that is not applicable in our situation. I haven't found a good workaround but am probably going to have to do a journal entry to record these excess payments as income rather than unearned income/customer credit. Any suggestions on a better way to do this, or whether the ability to split payments between income line items is a possibility? Thank you!
