I Hi all! Has anyone automated late fees / finance charge invoices before? What did your solution look like? If you haven't done it before, what would your approach look like?

I would probably approach this with a map/reduce script to find invoices that are past-due, and not currently billed a late fee (SuiteQL should make this easy enough). Validate that the looked up invoice isn't a late-fee, and then once you have the list. Create new invoice records through n/record with the late fee.

Thanks for the reply! To make sure I understand you correctly, you mean a standard invoice with a "Finance Charge" as a line item rather than creating an actual Finance Charge Invoice as defined here? https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_N1301640.html

That's what our implementation partner did for us. I'm not sure what went into the discussions on why they implemented it that way.

I've seen it done that way before too. From what I can tell from conversations on Reddit and StackOverflow and such, the Finance Charge Invoice is not accessible to Suitescript so people use a regular invoice with a finance charge item to simulate it.
