Be the price behind every quote in your market
When a homeowner prices a build, Modern GBQ resolves each line to a real product. Published offers come first. If your prices are in the system, your products are what gets quoted.

How it works
What you actually do
- 1
Get verified
Register your business and our staff verify it before anything you publish can price a quote.
- 2
Get your products in
Three ways, whichever suits: enter them by hand, upload a price list as CSV, or confirm and correct what our sourcing agent has already found for you.
- 3
Keep them current
Your workspace shows what has lapsed and what expires within thirty days, and extends validity in one click. A stale price is worse than no price.
- 4
Get chosen
A published offer beats every other price source. When a quote is approved with your product on it, you are told.
Worth knowing first
The honest limits
Better to read these now than to discover them after signing up.
- Pricing never waits on you. If your price is not there, the quote uses the next best source and says so — so a slow response costs you the line, not the homeowner their estimate.
- Prices our sourcing agent finds are drafts until a person reviews them. Nothing is published in your name without review.
- Some catalogue actions are still staff-managed while the governance rules are settled.
