Fix your stupid-*** form. Why can't I paste into the "confirm account number" field?

Seriously, this is 101-level HTML.

Allow copy-paste to avoid data entry errors. This is computing 101. Disabling copy-paste is:
a) a barrier to accessibility,
b) a source of data quality issues
c) antisocial and anti-consumer

I will not use your service again until this idiocy is fixed.

Add a payment memo line for the payor (and payee). So I can notate "June 2022 service"; "July 2022 service"

The form resets when a user switches card type – "debit" or "credit". Then they have to re-enter info. You could require a "debit" or "credit" choice prior to card info so that an oversight mistake is less likely.

Printed receipt should include last 4 digits of CC used. Its on the emailed payment receipt but not on the printed receipt. Also the printed version should be attached as a PDF to the email confirmation.

When I bill a subcustomer (even with "bill with parent customer" marked), I have to manually enter the email and mailing address of the customer. This should autopopulate unless edited otherwise.

When the techs finished service I had to ask for a paper invoice. They could not provide one for me with the amount that we would owe.

I have my routing and account number in a Google Doc for a situation like this when I pay from my account. There's no option to paste the account number in the second field. I keep those numbers so I can easily copy/paste them without a need to type them manually which causes mistakes in the first place. If this is a way to reduce the number of mistakes you accidentally made it more error prone by forcing me to put the number manually.

The complete vendor contact information should be on the invoice, this will expedite issue resolution

The invoice should show the specific dates, i.e. 5-1-22-to 5-31-22, not just 'monthly fee. Thank you.

Sometimes I forget to click credit first and when I do, it clears out the entry fields. So then i have to reenter the data. Alternatively, force the user to choose the payment method first, and then show the fields.

My wife and I have been Alpine Springs customers for about two months. In that time, we've gotten perhaps six 5-gallon bottles. The service has been fine, but we received our first invoice this evening. It was only for two bottles and was purportedly a reminder for an invoice that was due two weeks ago. I paid promptly, but still don't know where our account stands or what other invoices may be unknowingly delinquent.

display the date of payment in addition to the other information listed on the screen after confirmation of payment. The screen displays the amount paid, who its paid to the payment mehod, auth ID due date, invoice amount and total. a screen shot of the info with the date paid is easier on a mobile phone than downloading the receipt or invoice.

There are 3 actions available. Two had options: receipt or invoice.

The third, implied, is "close the page because you're done". Every action on a page should have a control related to that action: that's basic UI design.

When tabbing through the boxes, it the first several as expected. However, the last line was broken.

On the last line was NAME, then ZIP. However, when tabbing, it went to ZIP then NAME. Ew. Please fix that. Thanks!

Add student name field

Neither the receipt for payment nor the invoice file names includes the date issued. This should be automatic.
