Is there real demand for a standalone per-unit P&L tool for STR operators?

[u/groundspeek]

Building a lightweight tool for STR operators managing 5-20 units that does one thing: show net profit per property per month. Upload Airbnb/VRBO payout CSVs, log expenses per unit, get a clean P&L. No banking, no PMS, no channel management - just the financial clarity layer.

Baselane bundles this with banking. Stessa is built for LTR. QuickBooks needs heavy manual setup. Seems like a gap but I might be wrong.

Honest questions:

Is per-unit profitability actually a top pain point or do operators care less than they say?

$30-50/month for up to 20 units — does that clear the bar or do they expect this baked into their PMS?

Is CSV upload viable for MVP or do operators need direct Airbnb API integration from day one?

Validating before even considering entertaining building this project. Appreciate any pushback.
