How One Builder Turned Estimates Into Contracts with ProntoCalc
In the highly competitive construction industry, winning a bid often comes down to one thing: trust. When clients see that your proposal is transparent, well-organised, and backed by data, they’re far more likely to choose you over the competition. That’s exactly what happened for Monsaldale builders, a local contractor that went from average win rates to closing 30% more contracts—just by switching to ProntoCalc’s detailed cost breakdowns.
Not only that but each contract won and managed using Prontocalc was profitable. Profit margins are increased when you used Prontocalc.
The Challenge: Vague Estimates, Lost Opportunities
Before using ProntoCalc, Monsaldale Builders relied on spreadsheet-based estimates — manual, inconsistent, and easy to misinterpret. “Clients would ask where a number came from, and we’d scramble to justify it,” said owner Mike Serrano. “It made us look unprepared, even when we weren’t.”
Too often, estimates are a few words explaining the project and one single figure. Prontocalc ensures trust between the customer and the contractor.
The Solution: Transparency Through ProntoCalc
ProntoCalc gave Monsaldale a way to present their numbers with confidence. Each bid included:
- Line-by-line material and labor breakdowns
- Real-time pricing updates to reflect market conditions
- Built-in contingencies and scope-specific allowances
- Customisable formats for different client types—residential, commercial, municipal
Using ProntoCalc’s intuitive platform, Monsaldale could produce professional-grade cost reports in a fraction of the time it used to take. More importantly, they could clearly show the why behind every pound.
The Results: A 30% Increase in Bid Wins
After adopting ProntoCalc, Monsadale Builders saw:
- 30% more bids awarded over a twelve-month period
- Fewer price disputes during project execution
- Faster approval cycles—clients didn’t need multiple rounds of clarification
- Improved internal efficiency, freeing up time for project planning instead of spreadsheet maintenance
- Increased profitability, every time
Boosting Profit Margins Through Smarter Project Management
Beyond winning more contracts, Monsaldale also saw a measurable increase in profit margins. By continuing to use ProntoCalc throughout the project lifecycle—not just at the estimating stage—they were able to:
- Track budgets in real time, flagging overspending before it got out of hand
- Control labor and material costs with precision
- Avoid scope creep by tying every change order back to detailed, documented estimates
- Improve vendor negotiations using accurate cost histories and forecasts
“ProntoCalc helped us plug the financial leaks we didn’t even know we had. We’re not just winning more work—we’re making more on every job.”
Client Feedback: “It Felt Like They Knew What They Were Doing”
One homeowner who chose Monsaldale over three other contractors noted, “Their proposal looked professional, and everything was broken down clearly. It felt like they knew what they were doing, and that gave us confidence.”
