How to resolve common problems with ISIS AR.
Incorrect AR Payment Posting? Here’s What to Do
If a payment was posted incorrectly in ISIS AR, contact the Cashiers Team with the following details:
- Where the payment was posted
- Where it should have been posted in ISIS AR
Prevent Future Posting Errors
If you receive an AR payment directly:
- Review the payment
- Identify the correct destination in ISIS AR
- Complete the required deposit form
- Use the Cashiers AR Deposits (Central Cashier Deposit Advice form, Excel)
- Include both the invoice number and the personal identification (PID) number.
- Submit payment and form
- Send both to the TritonPay Office for correct processing in ISIS.
Returned Checks: What Happens and What to Do
When a check is returned by the bank (due to insufficient funds, stop-payment, closed account, etc.), the TritonPay Office takes the following steps:
- The Cashiers Team:
- Creates an ISIS AR account for the payer.
- Posts a charge for the original check amount + $25 returned check fee.
- Issues a provisional credit to your general ledger account.
- The Account Holder:
- Must send a replacement payment (including the $25 fee) to the TritonPay office.
If You Receive the Replacement Check Instead:
- Deposit the check through the Cashiers Office requesting the payment be posted to the newly created AR account.
- Do not redeposit the check into your general ledger account.
