Invoice totals are often one cent off from the total of all line items added together, I assume because of rounding issues. Not urgent, but it does make handling these invoices more annoying for our finance team. Example invoice: Description | Quantity | Unit price | Amount SMS Segments | 45,472 | $0.014 | $636.61 MMS Segments | 3,954 | $0.04 | $158.16 Call Minutes | 7,688 | $0.03 | $230.64 Caller Session Minutes | 2,310 | $0.03 | $69.30 Amount paid: 1094.70 Adding totals together: 636.61 + 158.16 + 230.64 + 69.30 = 1,094.71
