Ask HN: What is the best accounting software for an R&D stage startup?

We're trying to figure out what sort of accounting software we should use for what is essentially cost management right now since we dont have any cashflows. A HN thread I found in 2016 seemed to conclude that quickbooks was probably the way to go, but I wonder if that still holds in 2019 with some of these new services like Pilot? Does anyone have any experience with these? Thanks!
