I tried paying my Corporate American Express bill online. The online form told me that the amount due was $2,420.53 (prefilling the box with that exact value), so I selected that balance and authorized payment. When I submitted the form I received the following error:

Error: The amount you attempted to pay exceeds the Total Outstanding Balance of 2420.5299999999997. Please reenter a payment amount that does not exceed this value.

Well, ok then!

  1. I wonder why a CC company would not accept an overpayment? It protects them against next month’s debt, they get to ‘use’ the money for a month and there’s no interest to pay on it.

  2. Wonder if they have never seen the Round() function before… or is this one of those times we should be trying to siphon off all the .00000000003 of a cent?

  3. I’ve done some heavy Web Service integration work with American Express, and this is 100% consistent with how well that went. Being the first customer for one of their new service corporate integrations offerings was fun – the WSDL wasn’t even valid!

  4. So now you will always owe them just under a cent – LOL
    Reminds me of a story where a guy received a final utility bill after he moved for $0.00. He ignored it, since he didn’t owe anything apparently, and then started getting collection notices, etc. After making a number of calls, he eventually had to send them a check for $0.00, which resolved it.
    Who knows if this is an urban legend type story, but I found it amusing.
