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
