Is there a way to use SuiteTax without a third party provider/tax engine? I want the fields and tax detail that SuiteTax provides, and we technically have a third-party provider (Vertex), but their NetSuite plug-in for SuiteTax is absolute garbage performance-wise which is a show-stopper for us, so we'd rather just use their API and set the the tax ourselves, but when I remove the Vertex bundle, NetSuite throws a hissy fit about not having tax engine in place.

Sure. You can do that. The SuiteTax feature should be available for everyone to enable in your account. Just remember once to turn it on, it can't be turned off again. It's a one-way ticket. You'll be looking to create a SuiteTax plug-in type script to call the API and perform the calculations. Here's an older doc which describes how the plugin should work and what functions are expected. I haven't been able to find a newer version of this document. I worked for a SuiteTax provider a few years back and created/maintained a SuiteTax plugin and it was pretty straight-forwrd. At my current company, we just migrated from Legacy tax to SuiteTax and I really wish we had written the plugin ourselves rather than relying on the vendor's plugin.

This is awesome! Lemme take a look and digest this. It's hilarious that you say you wish you'd written it yourself as that is kinda what we are planning after suffering through Vertex's plugin.

There were a couple of times we asked for changes from the vendor and they told us they couldn't do that. When presented with this doc and some sample code, they were suddenly happy to oblige. 🙂

Hey James, I work for the empire now and have seen this...its a bit like the old legacy model but very improved. still some limitattions. Buzz me if you have questions

Definitely will do after I take another look at it on Monday.
