The main cost driver is scope. An equipment rental company usually has a handful of repetitive jobs: answering quote requests, checking availability by phone, scheduling deliveries and pickups, handling damage deposits, and generating or chasing contract paperwork. Automating one of those, say quote requests, is a smaller build than a system that also checks live availability, books delivery windows, and manages deposit and contract paperwork together. The more of that chain a system needs to touch, and the more it needs to talk to your existing booking or inventory software, the more it costs to build.
The other driver is whether you want it built and handed off, or built and run. A one-time build that automates quote replies is cheaper than a system Precipitate operates on an ongoing basis, one that keeps working when a vendor's API changes, a form breaks, or an edge case shows up, and that escalates to a person when a judgment call is needed, like a disputed damage deposit or a customer asking for terms outside the standard contract. Operating a system month over month costs more than building it once, because someone is watching it and keeping it running instead of leaving it to fail quietly.
Precipitate does not publish a price list because the same system is worth different amounts to different rental businesses depending on call volume, fleet size, and how much staff time currently goes into this work. We quote each engagement on the value the system creates, not on hours spent building it. The honest way to judge whether it is worth it is to map your own repetitive work first, decide what a system can fully own versus what still needs a human, like inspecting returned equipment or handling a genuine dispute, and then have a short conversation with us about that specific list.
