The expensive mistake
A full schedule is not the same as a profitable business.
Most estimating sheets add up the costs you remembered. They do not protect you from the scope you missed, confused margin math, undocumented change orders, or the small costs that quietly consume the job.
BidArmor makes the risk visible before the price becomes a promise.
A disciplined bid workflow
From rough costs to a bid you can defend.
No complicated estimating software. No subscription. One practical Excel workflow built for working contractors.
Protect the scope
Run a 30-point check for the costs that quietly turn into free work after the bid is accepted.
Clear the Bid Gate
Compare floor, target, and stretch pricing—then GO, HOLD, or REPRICE before the proposal leaves your desk.
Control the job
Create the client proposal, price change orders separately, and compare estimated versus actual margin at closeout.
Inside BidArmor
Every stage of the bid. Connected.
See the estimate, pressure-test the scope, price change orders, and learn from the completed job without rebuilding your process in five separate files.
Estimate Builder
Build the real cost of the job.
Organize labor, material, subcontractor, equipment, delivery, allowances, tax, and custom line items—then apply overhead and contingency before price.
- Editable assumptions and cost lines
- Gross-margin pricing, not confused markup math
- Floor, target, and stretch price comparison
Scope Check
The costs you forget become free work.
Review access, permits, supervision, protection, waste, payment cost, warranty, closeout, and more before you commit.
Bid Gate
Don't send it until the bid clears.
GO when checks pass. HOLD when scope is unresolved. REPRICE when the proposed sell price falls below your floor.
Control + Review
Protect the margin after the bid, too.
Turn internal numbers into a clean client proposal, keep extra work out of the original scope, and compare actual performance against the estimate.
- Client-facing proposal and price summary
- Separate change-order pricing and payment status
- Estimated versus actual cost, profit, and margin
The math matters
Margin is not markup.
On a $12,046 loaded cost, confusing a 35% markup with a 35% gross margin leaves $2,270 of intended revenue out of the bid.

35% margin$18,533sell price

Straight answers.
Is this a subscription?+
No. BidArmor Estimator is a one-time digital purchase of the current workbook and included guide files.
Do I need Microsoft Excel?+
Microsoft Excel is strongly recommended. Other spreadsheet apps may alter formulas, validation menus, formatting, charts, or print layout.
Can I customize it?+
Yes. Change company information, rates, assumptions, line items, phases, descriptions, proposal notes, and project terms for your business.
Can my employees use it?+
Yes, within the same licensed business. The source files may not be shared with or used by separate businesses.
Does a GO result guarantee profit?+
No. GO means the configured workbook checks passed. Profitability still depends on accurate quantities, costs, labor, scope, execution, terms, and project conditions.
