Amount charged to credit card doesn't match cart total

[JeffLC]

I'm back over on this thread again. It appears the issue is not isolated to Better Together discounts.

I posted in the Better Together support forum but swguy said he'd never encountered an issue between BT and Authorize.net (AIM). Also, during some testing, I discovered the ZC order total also doesn't match the amount charged to the credit card for some other coupons I have defined even if I just used the basic ZC functionality. For example, I created a coupon a couple years ago for free shipping (by just checking the 'free shipping' box on the coupon page) and it works fine, i.e. the order total and amount charged to the credit card match. On the other hand, there is another coupon I created to give a $3.95 discount off the order total and it doesn't work, i.e. the order total and amount charged to the credit card don't match.

There is nothing in the debug logs about an error being encountered during checkout and the AIM_Debug file shows the incorrect amount being charged. I haven't been able to find a pattern for when the amount charged to the credit card doesn't reflect the discount. Where should I start looking?

Is your site a fresh 1.5.4 install or has it been progressively upgraded from previous ZC version(s)?

If you disable taxcloud, does anything change?

[JeffLC]

My ZC was upgraded from v1.3.9 (original install in 2011) to v1.5.4 a few months ago by swguy, so I'm confident it was done correctly.

RixStix - I believe you are on to something. I turned off Taxcloud and both the Better Together deal and the $3.95 discount coupon I mentioned in my earlier post worked correctly (order total and credit card charge match). When I turned Taxcloud back on and processed the exact same transactions, I had the discrepancy between the ZC order total and the amount charged to the credit card.

Now that it appears the source of the problem has been found, is there a simple fix?

There's a bug in their authorizenet_aim integration. A fix is posted on the Taxcloud support thread here:
