Frequently asked questions
My ACH payment was returned or rejected due to ‘Customer Advises/Corporate Customer advises not authorized.’ How do I resolve this?
As the payor, provide the Alliant company code 0000408976 to your bank or financial institution to allow Paymentus to debit your bank account. In addition, notify Alliant that you’ve completed this so we can request the account be removed from the negative file. Both items must be done to submit future ACH payments.
Do I get a receipt after making a payment?
Yes, Alliant Bill Pay sends a receipt to your account manager and to the email address you provide.
Can I set up automatic, recurring payments?
No, Alliant Bill Pay doesn't offer recurring payments.
What happens if my account doesn’t have enough funds for a payment?
Alliant Bill Pay rejects payments with insufficient funds. You can attempt the payment again using the same invoice numbers.
Can Alliant cancel or void a payment for me?
Yes, Alliant can cancel or void a payment the same day that the payment is made before the cut off time of 6:30 p.m. PST.
Can I pay with a credit card?
If the invoice doesn’t show a credit card payment option, it isn’t available for that invoice.
What’s the maximum amount I can pay?
For credit card payments, up to $999,999.99 per invoice. For ACH payments, up to $9,999,999.00 per invoice. For larger amounts, contact your account team.
How many payments can I make in one day?

Can I spread one payment across multiple invoices?

Does Alliant Bill Pay accept partial payments on an invoice?

How quickly does my payment reflect in my account after submission?

What should I do if I can’t load my invoice or if there’s an error?
