When you convert an order to a bill you are changing the transaction type, as such, the recorded data will stay the same. If you manually change the payment terms when recording an order that change will be retained when the order is converted to a bill.
Don't hesitate to post again if you need help in the future.
Why does it not use the terms in the supplier file?
The people doing the orders will not change the trading terms, most of the time they don't know them. I have set the trading terms on the supplier file, so it would make sense to me that any order done for a supplier should automatically get their trading terms on the order. Having every order automatically set to COD is just another thing that wastes time and creates more work..
My apologies I misunderstood your post and thought you were changing the orders to COD. The default supplier terms are set in Setup>>Preferences>>Purchases>>Terms. However, the default terms are overridden by the terms selected in the supplier card. For example, I set the default terms as COD and the supplier card terms as Prepaid, when I selected that supplier in Enter Purchases>>Order the terms changed to Prepaid.
If you are seeing something different please provide screenshots of the supplier card and an order so that I can look into this for you.
Please find screenshots attached.
Some explanation.
The person doing the purchase orders finds the online version easier to use. The online verson adds COD as the terms no matter what is in the supplier card.
The desktop version, when you add a purchase order through that, has the correct terms.
For some reason the terms from the supplier is not coming accross when purchase orders are created online.
