The difference is verification, not extraction
Both tools read a bill and give you fields. The question neither marketing page usually answers is what it costs you to be sure those fields are right.
If every extracted value looks equally confident, every value costs the same to check — which means the saving is smaller than the extraction speed suggests. Scoring each field separately, and linking each one to the exact region it was read from, is what makes checking selective instead of total.
Where Dext is the better answer
Volume capture with many submitters. Dext's submission paths and its mobile app are mature, and a firm whose actual problem is getting paperwork out of clients' hands will feel that maturity immediately.
Deployment scale, too. Dext is established and widely used; we are early access. If you need a tool you can roll out to thirty clients next month with a support org behind it, that is not us yet, and we would rather say so here than in a sales call.
Where this is the better answer
When a qualified reviewer is the expensive resource and their time is going into confirming machine output rather than deciding anything.
And when you need the trail afterwards: every approval and rejection carries a memo and lands in an append-only audit entry, and every figure in the books is one click from the page it was read off.
What does not change either way
Your accounting platform. Both tools sit alongside QuickBooks Online or Xero rather than replacing them — there is no migration in either direction.
So this is not a platform decision. It is a decision about which half of the job you want automated.
