Frequently asked questions
Can I use my own equipment and pricing?
Yes. Proposals are built from your own equipment catalogue and your margins, so the numbers reflect how you actually price - not a generic template.
Can customers sign and pay online?
Yes. The customer can e-sign the proposal and pay a deposit online in the same flow, so you can close while the job is hot instead of waiting on posted paperwork.
Can I show finance on the proposal?
Yes. Every proposal can show a monthly finance payment beside the upfront price, so the customer weighs an affordable payment rather than a big number. The finance itself is provided by regulated finance partners, not by you.
How long does it take to build a quote?
You pick the system and the branded proposal builds itself, so you can send a professional quote in minutes rather than the days it can take elsewhere.
