It sounds like Bill.com is super great for non-PO vendor billing use cases & not super great for any PO stuff.

We recently implemented Bill.com and mostly do PO billing/payment. The main two issues we ran into (and had to create custom workarounds for) were that they don't support Item Groups - any POs with an Item Group on it never synced to Bill.com - and they don't utilize the native terms-based discounts for payments (e.g. if you have a Vendor that gives you 2% 10 Net-30 terms, in NetSuite you can pay $98 on a $100 bill and it's considered paid in full, but in Bill.com that discount is never taken when the payment is created/synced back to NetSuite).

Thanks @MTNathan. That is super helpful. We are hoping that happy path purchase order billing works great & we can solve some of the edge cases through workaround like you suggested.

does Bill.com works with Vendor Prepayment?

@NetSuite Ninja We were already looking for an excuse to move away from Item Groups because they're a pain to work with in customization, so this just pushed us over the edge there - if you're able to work around those things, it seems like the integration works pretty well (with the caveat that we've only really been using it for a few months with a comparatively low volume of POs).

@Suitestallion the Bill.com docs don’t specify Vendor Prepayment stuff. If you find out please let me know.
