Three ways configurators produce a price
Square-foot multipliers
Total the area, multiply by a rate. Fast, and wrong in a predictable direction: it averages. Simple buildings get overpriced and you lose the bid. Complicated buildings get underpriced and you eat it on the build.
Option-based adders
A base price per size band, plus fixed amounts per option. Better, but it can't see interaction effects. Adding a lean-to doesn't only add lean-to material — it changes the host wall framing and the trim at the intersection. A flat adder has no way to know that.
Model-derived pricing
The configurator builds the structure member by member, produces a takeoff with lengths, and prices that takeoff against your material costs. The price tracks the building because it's derived from the building. This is the one worth having, and it's the one that requires the framing to actually be modeled. Why most configurators skip that step.
The diagnostic question: ask how many columns are in the building you just designed. If the tool can't tell you, it isn't pricing from the building — it's pricing from the dimensions.
Who controls the numbers
This is the part people don't ask about until it's a problem.
Can you update your own prices? If changing a lumber cost means emailing support and waiting, you will quote stale numbers. Material prices move faster than support tickets.
Is it your cost structure or a generic one? Your supplier pricing, your margins, your freight. A generic table is somebody's average, and your business doesn't run on averages.
Can you price differently by region, dealer or customer type? If you sell through multiple channels or across a wide area, one price list won't cover it.
What happens on the customer-facing side? If there's a configurator on your website, the number a customer sees becomes the number you're anchored to. Showing a price you can't honor is worse than showing no price at all.
Custom pricing isn't a feature, it's the foundation
Every building business prices differently. Different suppliers, different volumes, different margins by product line, different freight. A configurator that treats pricing as a fixed table is solving somebody else's problem.
What you want is a pricing layer you own: your own material costs mapped onto the components the model produces, editable by you, with the model handling the arithmetic of how many and how long.
What to test during a trial
- Design a building you'd really quote. Not a rectangle — include a lean-to and a large overhead door.
- Look at the material list. Does it show lengths, or only counts? Why lengths matter.
- Change one dimension and watch whether the member counts and price both move.
- Add a lean-to and check whether the host building's members changed.
- Update a material price yourself and see how long it takes.
- Compare the total against a takeoff you did by hand for the same building. That's the real test.
Step six is the one most people skip and the only one that actually proves anything.
How Redline handles it
Redline 3D models the structure member by member across post frame, red iron and stick frame, including multi-level interior framing, then produces a takeoff with sizes and lengths attached. Your material costs and margins drive the pricing, and you control them.
The same model feeds your website configurator, so the price a customer sees and the price your team quotes come from one source rather than two systems that drift apart.
