Before Slabstack, quoting at Carew Concrete felt like detective work. Sales reps would dig through old spreadsheets, searching for past bids with no way to confirm if pricing was still valid or accurate. On more than one occasion, they had to call customers back hours later to correct errors after realizing costs had changed.
With no centralized quoting system or visibility across reps, pricing discipline was inconsistent. One rep would quote a job at one margin, another might unknowingly undercut it. There were no guardrails, no live cost data, and no easy way to track performance. Their team was working in silos and spent a lot of time in manual admin work.
“Slabstack has taken a process that used to eat up a ton of time and made it simple—we always know whether things are going the way we planned.”
John Malcolm, Vice President | Carew Concrete
Before Slabstack: Quoting without guardrails
No centralized quoting system
Carew’s sales team relied on spreadsheets and fragmented tools to manage quotes, with each rep maintaining their own version of “the process.”
This lack of a unified system created inconsistencies in pricing, duplication of work, and higher chances of quoting errors. Without a central source of truth, it was nearly impossible to maintain accountability or track quoting activity across locations.
Loose quoting discipline
Without margin calculators or automated checks, quotes were often driven by gut feel. Reps would manually estimate pricing, sometimes under pressure to close deals—which led to inconsistent margins and reactive pricing.
There was no way to enforce minimum thresholds, making underbidding common and eroding profitability.
Lack of visibility
Finding old quotes or understanding historical pricing patterns required digging through email chains or scattered files. Sales teams had no easy way to compare bids across territories or track win/loss performance. This lack of visibility slowed response time, led to missed opportunities and internal price undercutting.
Unreliable legacy tools
Carew had previously tried implementing Command’s mobile sales tool, but it fell short of expectations. The system was clunky, difficult to use, and lacked integration with core dispatch data. After months of effort, it still couldn’t deliver the visibility or control Carew needed, prompting them to search for a more purpose-built solution.
“The live information flowing between Slabstack and Command works better than Command’s own MobileSales did. Slabstack even pulls data back from Command—something MobileSales never managed.”
John Malcolm, Vice President | Carew Concrete
The solution: How Carew Concrete achieved >98% quote accuracy with Slabstack
After evaluating multiple vendors—including Salesforce, PriceBee, and a reimplementation of their previous tool—Carew Concrete unanimously chose Slabstack.
Unlike horizontal CRMs or bolt-on tools, Slabstack was purpose-built for concrete and aggregate producers. It offered the deep Command integration, margin visibility, and quoting discipline they needed to scale with confidence.
Built-in margin controls
Slabstack introduced automated margin calculators directly into the quoting workflow. Sales reps could see real-time margin impact as they built a quote, with built-in guardrails to prevent underbidding. This brought clarity and consistency across the team and removed guesswork from pricing decisions.
Command integration out of the box
Unlike other tools that required workarounds or manual syncs, Slabstack came ready with a two-way integration into Command Dispatch. Quotes could be informed by live cost data and pushed seamlessly into dispatch workflows. It didn’t just improve accuracy—it enabled real-time collaboration between sales and operations.
Structured workflows for consistent bids
Carew adopted a more disciplined quoting approach by introducing a sales administrator role, supported by Slabstack’s approval flows. Every quote now follows a clear process with checks, templates, and audit trails. Reps still move fast but every bid is now aligned with the company’s pricing strategy.
Easy to use, quick to adopt
One of the biggest differentiators was how intuitive Slabstack was. Compared to their previous system, reps found it easy to navigate and start using right away. There was no steep learning curve, which meant faster adoption and less reliance on training or IT support.
“We chose Slabstack because it isn’t just a tool for today; the team is committed to building the features the ready-mix and aggregate business has always needed.”
John Malcolm, Vice President | Carew Concrete
The Outcome: Higher margins and smarter bidding
Just months after implementation, Carew began seeing measurable improvements across sales performance, margin capture, and team alignment. With better tools and real-time visibility, quoting became faster and more strategic.
Margins improved significantly
With clear pricing guardrails and up-to-date material costs built into every quote, Carew’s team no longer had to guess or rely on outdated spreadsheets. Bids reflected true profitability from day one. This shift in discipline led to stronger financial performance across the business.
Increased quote accuracy from 50% to near 100%
Before Slabstack, quote accuracy hovered around the halfway mark. Today, the team bids with near-total confidence, knowing the numbers they send out are backed by clean data and reviewed workflows. That confidence made a visible difference in how projects are quoted, tracked, and closed.
Quoting faster, without cutting corners
Speed doesn’t come at the expense of accuracy. With Slabstack, Carew reduces turnaround time on bids while keeping every quote aligned to target margins. Sales reps no longer waste time hunting down pricing or fixing errors—they move faster, with less risk.
Transparency across the pipeline
Every stakeholder now has full visibility into who’s bidding what, and where. Slabstack made it easy to access historical quotes, compare pricing by region, and avoid internal competition or overlap. This alignment has improved consistency, reduced confusion, and helped strengthen customer relationships.
“We’re bidding every project available to us now, and it’s easy to verify that in real time. Our consistency in the marketplace has improved tremendously.”

Beyond software: A growth partner for what’s next
Slabstack has helped reshape how Carew Concrete approaches sales, bringing structure, speed, and visibility to a process that once ran on guesswork. With real-time Command integration, centralized data, and a disciplined quoting engine, the team now bids smarter, wins more, and protects margin with every project.
But the impact goes beyond software.
Through weekly touchpoints and a true partnership model, Slabstack continues to support Carew’s growth—refining workflows, solving problems quickly, and building features that match real-world needs.
“The weekly cadence with the Slabstack team means there’s never a long gap between finding an issue and fixing it. That collaboration is a real differentiator.”
