Also smaller less sophisticated vendors (I include my company in this) simply enter your remittance information once in their banking system on the first invoice. We aren't going to want to update it every time. They could have it randomize per vendor I suppose but all that is a lot of hassle when you can just put five accounts in the Payment Advice field in your accounting software and let the vendors do with it as they choose.
