Pro Tips
- *Start with one stubborn workflow, ship in two weeks, and charge for the next must have feature before expanding scope.
- *Bake in audit evidence from day one with timestamps, factor provenance, and reviewer sign offs to avoid painful rework.
- *Offer simple pricing aligned to the buyer metric meters, facilities, suppliers, or reports so procurement can approve quickly.
- *Integrate lightly with CSV and email ingestion first, then add APIs for the top two systems your customers already use.
- *Pair the product with a small implementation project or quarterly advisory hours to accelerate adoption and reduce churn.
