Spreadsheets look like a place where every formula, rate, and note sits neatly in its own cell. But for aggregates suppliers, those same spreadsheets quietly drain profit. 

When you’re quoting jobs that run thousands of tons, even a few cents per ton can decide whether you make or lose money. And in a business where margins are already so thin, that kind of leakage adds up fast.

If you’ve ever wondered why your numbers don’t quite match finance’s or why a profitable job turned out to be break-even, the answer might be hiding in your spreadsheets. 

In this blog, we’ll uncover how manual quoting tools erode margins every day and what suppliers can do to take control again.

3 ways spreadsheets give a false sense of control to aggregate suppliers

At first glance, spreadsheets seem like the ultimate control tool, and they usually start as such, where every calculation is visible and every change tracked. 

But over time, this system starts breaking down. Especially when each plant, region, or rep begins to maintain their own version.

So formulas break. Freight rates drift. Cost assumptions go unchecked. 

One rep updates a file while another sends a quote from an older version. What looks like precision is actually fragmentation. That fragmentation is where profit starts to slip away for aggregates suppliers.

Let’s look at the three most common ways this happens.

1. Outdated numbers on spreadsheets quietly erase profit

Aggregates pricing is volatile and shifts constantly: Diesel, explosives, labor, and haul rates all change from week to week and sometimes even daily. 

Yet the quotes for many aggregates suppliers still rely on spreadsheets built months ago. 

Consider this: Even a $0.15 per ton gap might seem harmless, but multiply that across a 50,000-ton order and you’re looking at over $11,000 gone before anyone notices.

When cost sheets become outdated, reps often quote yesterday’s prices while paying today’s costs. And the longer those updates lag, the more profit margin you lose. 

2. Freight affects margins 

Freight is one of the hardest pieces to track manually, and one of the easiest places for profit to vanish. 

Spreadsheets often rely on flat zone rates or simplified distance tables that ignore variables like tolls, backhauls, or surcharges. When fuel prices or haul distances shift, the spreadsheet doesn’t adjust on its own.

That means a quote might look perfectly profitable on paper but lose cents or even dollars per ton once the trucks start rolling. Those small discrepancies pile up over dozens of jobs and quickly turn into margin erosion that few can trace back to their source.

3. Version chaos creates margin confusion

Every time someone in your team copies or emails a spreadsheet, a new version of the truth is born. Sales, dispatch, and finance teams often operate on slightly different datasets, and nobody’s sure which one is correct. 

So your team ends up with conflicting quotes, internal undercutting, and inconsistent customer pricing. 

Beyond errors, version chaos also hurts trust within the team and with customers. When a client gets two different quotes for the same job, they don’t see it as a small mistake. They see a company that can’t keep its numbers straight.

Let's understand the repercussions of relying on spreadsheets in detail below. 

What’s the real cost of manual quoting for aggregate suppliers? 

Every hour a rep spends chasing freight rates, verifying approvals, or double-checking formulas is an hour not spent selling.

Over time, these inefficiencies become a hidden tax on every sale.

Even when quotes are accurate, the manual process behind them costs suppliers more than they realize. 

A rep might spend half a day collecting freight updates from different plants, copy them into multiple sheets, and wait for a manager to sign off. 

By the time that quote reaches the customer, the numbers might already be outdated. 

These slow, manual workflows also make it difficult to see why margins shift from one region to another. Without clear visibility into trends, like which plants quote fastest, which jobs lose the most freight, or where discounts are creeping in, managers are left reacting instead of improving performance.

But the good news is these issues can be fixed, and it doesn’t require overhauling how your team works. Here’s how. 

How can aggregates suppliers escape the spreadsheet trap?

Moving away from spreadsheets doesn’t require a complete overhaul of your existing workflows. Here are a few simple steps you can take today to make sure your team is avoiding rookie errors while quoting through spreadsheets. 

1. Centralize cost and freight data: Bring all cost and freight information into one shared file or dashboard. When everyone uses the same numbers, you reduce duplicate work and quoting errors.

2. Refresh inputs weekly: Set a consistent routine to update diesel, freight, and material costs. Some teams automate this through supplier emails or dispatch exports ensuring the numbers never go stale.

3. Set margin floors: Define your minimum profit thresholds by material or region. If a quote falls below that level, it should automatically trigger an approval. This keeps pricing disciplined without slowing sales down.

4. Track win/loss data: Record which quotes were accepted or lost and why. Over time, this builds a picture of pricing trends, showing where margins are shrinking, which customers buy on price, and where your team is strongest. 

Each of these steps builds clarity into your sales process. But even getting to this point can take a lot of manual effort and wasted hours. 

An easier way to reduce your dependency on spreadsheets is to use a specific CRM for aggregates suppliers like Slabstack. Let’s explore more.

3. 5 Signs You Need a Better CRM as a Building Material Supplier

Author: Aymeric Halvarsson

Material costs in construction rarely stay the same for long. Cement, diesel, and freight rates can change from week to week, sometimes even daily. Despite this, many suppliers continue to rely on outdated price sheets or spreadsheets, quoting numbers that no longer accurately reflect their actual costs. This leads to shrinking margins, lost bids, and sales teams stuck trying to reconcile the gap.

Dynamic pricing changes that by keeping quotes aligned with current costs, protecting profitability, and enabling sales teams to act quickly without losing accuracy. 

In this article, we’ll look at what dynamic pricing means for construction suppliers, why static pricing creates risk, and how to approach putting it into practice.

What is dynamic pricing in construction materials?

At its core, dynamic pricing is the ability to adjust your prices in real time based on changing input costs, market conditions, and defined profit guardrails. While it’s common in industries like e-commerce or hospitality, construction suppliers have been slower to adopt it, even though the payoff can be substantial.

In our industry, dynamic pricing isn’t about sudden, unpredictable spikes you might see in consumer services like ridesharing; it’s about steady, rules-based adjustments that protect your margins. It’s about maintaining profitability by:

When every rep is working from the same current data, you remove guesswork and internal underbidding. That means fewer surprises when costs rise and better consistency across your sales team. To understand the importance of dynamic pricing, let’s take a look at how static pricing erodes your profits. 

Why is static pricing risky for construction suppliers? 

Many suppliers default to static pricing, keeping the same rates for weeks or even months regardless of cost changes, because it seems straightforward. In practice, this approach quietly eats into profit. Here’s why it’s such a silent margin killer:

Imagine quoting $130 per yard when your current cost is $135—what looked like a healthy price on paper is actually locking in a loss because your costs have already climbed past your outdated rate. That’s $5 of margin gone instantly. Over hundreds or thousands of yards, it’s the difference between a profitable quarter and a loss.

But the good news is that opting for dynamic pricing eliminates these pitfalls. Let’s look at the benefits.

Benefits of dynamic pricing in B2B construction 

Dynamic pricing isn’t just about protecting margins; it’s also a way to make your sales process more resilient and informed. When implemented well, it helps your team make faster, more confident decisions. Here’s how. 

Margin protection without slowing quotes

Built-in guardrails ensure every quote meets your minimum profit targets. Instead of slowing reps down with manual checks, the system enforces discipline automatically.

Consistency across the sales team

When every rep draws from the same live cost data, you eliminate the risk of internal undercutting and build customer trust through uniform pricing.

Less need for approvals

Approval bottlenecks disappear with dynamic pricing because alerts trigger only when a quote breaks a defined threshold, freeing managers to focus on strategic deals instead of routine oversight.

Pricing intelligence

Detailed tracking of pricing patterns across customers, regions, and reps turns every quote into usable market insight, helping you refine strategies and spot opportunities before competitors do.

These benefits add up quickly, showing that dynamic pricing is more than a cost control tool, it’s a competitive advantage. But how do you implement it in your business? Let’s find out. 

How to get started with dynamic pricing for your business?

Making the shift from static to dynamic pricing works best when you break it into clear, practical steps. 

Finally, choose technology that fits naturally into your existing workflow. Because doing all of this manually—tracking live cost changes, applying pricing rules, and keeping dispatch in sync—can consume hours each week and still leave room for errors. 

The right tool should pull in live cost data, apply your pricing logic automatically, and integrate directly with your dispatch systems so nothing slips through the cracks.

This is exactly where Slabstack comes in, eliminating manual busywork while keeping every quote accurate and profitable.

6. Building Materials Sales Training: 5 steps to coach your sales team on profit vs volume

In ready-mix concrete, chasing more volume might seem like the fastest way to grow revenue. But beneath that logic is a hidden cost that’s often ignored: profit margin erosion.

Consider a familiar scenario. 

A sales rep drops the price by just $1 per cubic yard to win a subdivision pour. Seems harmless, right? But by the time that job is completed, the plant’s trucks have run extra shifts, cash flow is squeezed, and the total profit hasn’t budged; if anything, it’s shrunk.

This blog unpacks the numbers behind that decision and how producers can shift from price-first to margin-first quoting.

The math behind margin erosion

Before we get into strategies, let’s look at the numbers that drive ready mix profitability and how even a small change can lead to margin erosion.

Material (or gross) margin per cubic yard = (Revenue/yd – Material Cost/yd)

This margin is the single most important number for a concrete producer. It’s what’s left to cover fixed costs, profit, and reinvestment after paying for raw materials. Even a small dent in it can quickly scale into a major hit across high volumes.

Here’s a breakdown with an example:

Say you’re selling at $160/yd with a cost of $72/yd. That’s an $88 margin, or 55%.

If you drop your price to $159,  your margin also drops to $87. To earn the same $1,000 in profit, you now need to pour more yards.

Read on to understand this in more detail. 

The “$1-drop” formula: Why low-margin jobs are unsustainable

What does a $1 discount actually cost your business? It’s easy to overlook how much impact a small discount has on overall profitability, but it adds up faster than you think.

Here’s the formula to calculate how much extra volume you’ll need to pour just to break even: 

Break-even yards = (Current margin ÷ (Current margin – $1)) × Current volume

Let’s walk through an example:

Now, drop your price by $1. Your margin becomes $87.00 per yard.

To make the same $4.400 million profit, you now need to deliver 50,575 yards—an increase of 575 yards or 1.15% more volume.

At first glance, 1.15% might not seem like much. But that’s 575 more cubic yards your trucks need to haul, your team needs to batch, and your plant needs to produce, with no increase in profit. 

And that’s assuming all your costs stay flat, which they rarely do.

For producers with thinner starting margins, the volume increase needed is even higher. A lower margin means the cost of discounting compounds even faster.

To avoid this, you might think that adding more volume will solve the problem. But in most cases, that added volume comes with higher costs, tighter cash flow, and capacity strains that erode the very profits you're trying to preserve. 

Why “we’ll make it up on volume” doesn’t work 

On paper, chasing more work seems like a smart hedge. But in reality, it strains every part of your operation.

Many building and construction material suppliers feel the pain of shrinking margins, but the reasons often aren’t as obvious as they seem. You might think it's external factors like market competition, but it’s often internal inefficiencies like bad data and outdated processes that lead to losing margins. 

In this blog, we’ll break down five internal hidden issues that silently kill your margins and explain how efficient suppliers are turning things around. If you want to stop underbidding yourself, improve quote accuracy, and win more profitable deals, this one's for you.

Key takeaways 

5 hidden issues that are killing your margins (and your win rate)

These five issues often go unnoticed until it’s too late, costing you deals you should be winning and profits you should be earning.

1. Outdated cost data leads to inaccurate quotes

Prices of construction materials like cement and additives can shift rapidly—especially as suppliers explore greener, more cost-effective alternatives like SCMs.

As a result, quoting from outdated spreadsheets causes misalignment between actual costs and bid values.

Your reps could be using numbers that are weeks or months old, and that gap means you risk either underpricing and eroding your margin or overpricing and losing the bid entirely.

Without live cost data, you're quoting on outdated assumptions, and in a business where pennies per cubic yard make a difference, those assumptions can add up to thousands in lost revenue. 

2. No visibility across teams causes internal underbidding

When your sales reps can’t see what their peers are quoting, they end up competing with each other. One rep hears a customer went with a lower price and immediately slashes their next quote—not realizing it came from their own team. 

This kind of internal undercutting happens more than you think, especially in companies using siloed tools or spreadsheets. It drives down your average price and creates a race to the bottom, where everyone loses.

3. Slow quote turnaround and lack of oversight over rep behavior

In this industry, whoever gets the first accurate quote usually wins. But if your quoting process is slow, manual, and dependent on approvals from busy managers, you’re often too late. 

Worse, without controls in place, low-margin deals can slip through simply because no one double-checked them before they were sent. The right quote at the wrong time, or the wrong quote at any time, hurts your ability to grow and protect profitability.

4. No centralized view of win/loss data

If your sales team doesn’t know why they won or lost the last ten deals, they’ll keep guessing. 

And those guesses can be costly. Without centralized tracking of win/loss data, patterns are missed. Maybe you're always losing in a certain region or on a specific product line. Maybe a competitor is undercutting you consistently, or your lead times are too long. 

Without this data, you can’t adapt, improve, or optimize your quoting strategy. Every lost deal becomes a missed opportunity to get better.

5. Lack of forecasting & demand visibility

Many suppliers underestimate the value of quoting data as an early signal of future demand. 

If you can’t see what’s coming, you can’t prepare your plants, adjust inventory, or adapt your pricing in time. Without forecasting tools, decisions get made based on gut feel rather than data. 

That leads to overstocking, missed revenue from rush jobs, or even unprofitable work due to poorly timed price strategies.

But the good news is that these issues are fixable. Read on to get some practical tips on how you can improve efficiency as a building and construction materials supplier.

What winning suppliers do differently

Fixing these challenges doesn’t require an overhaul, just a smarter approach. The most successful suppliers have adopted a few key habits that consistently protect and grow their margins. Here’s how. 

Quote with live pricing, not static spreadsheets

Getting accurate, real-time data into your quotes is one of the fastest ways to protect your margins. Instead of quoting based on outdated spreadsheets, forward-thinking teams use tools that automatically sync material, freight, and fuel prices from dispatch. 

This ensures that every quote reflects today’s costs, not last month’s estimates. 

Even if your team still uses spreadsheets, a simple recurring update using supplier emails or dispatch exports can significantly improve quoting accuracy.

Standardize pricing logic and enforce margin floors

Clear pricing rules create guardrails that protect your profitability. By enforcing margin floors and standard pricing logic, you reduce the chances of accidental underbidding. This kind of discipline ensures that while reps still have autonomy, they aren't making pricing decisions that hurt the business. 

To start, even a basic pricing matrix in Excel with color-coded margin bands can help you create a clear view of acceptable quote ranges.

They use templated quoting workflows for speed and control

Templates help ensure every quote is consistent, accurate, and aligned with your margin goals. A quoting workflow allows reps to pull in pre-bundled materials, apply pricing logic, and get manager approvals automatically.

That reduces delays, eliminates manual errors, and frees up time to focus on customers. 

Even with basic tools like Excel or Word, templated quote formats with embedded rules can have a big impact. You can define pricing structures, bundle common material combinations, and include standard terms or margin checks.

Track every quote and learn from the data

Every quote—won or lost—holds insight into how your business operates. Capturing why deals fall through or succeed helps you refine your strategy with every bid. By tagging lost quotes with reasons like "price," "timing," or "spec mismatch," you can uncover patterns and course-correct quickly.

You could start this process by creating a shared spreadsheet where your team can manually tag each lost quote with a reason to help start this feedback loop.

Use forecasting to price and plan proactively

Forecasting accurately helps your sales and operations teams stay in sync. Instead of reacting to last-minute orders, use historical quote volumes and win rates to estimate future demand. 

This allows you to plan inventory, prep plants, and adjust pricing strategy before demand spikes.

Start by combining monthly quote volume with historical win rates to estimate demand and pricing strategy for the next quarter.

All the tactics we just mentioned work, but they also require time, spreadsheets, and a level of manual upkeep that most teams simply can’t sustain. That’s where a cost management software for construction material suppliers can help. Read on to know how. 

How Slabstack helps you quote smarter, win more, and protect your margins

Slabstack is purpose-built software for building and construction material suppliers that pays for itself in as little as 60 days.


It brings quoting, pricing, forecasting, and performance analytics into one easy-to-use platform, so you can protect every margin point without slowing down your sales team. 

Real-time cost feeds eliminate quoting errors

No more quoting off stale spreadsheets. Slabstack syncs with your dispatch systems like Command Alkon and Sysdyne to pull the latest material, freight, and fuel costs, so every quote reflects today’s numbers. This real-time visibility ensures that you're never underquoting due to outdated inputs, helping you stay competitive without compromising on profit.

Sales rep guardrails prevent underbidding

Set minimum margin thresholds and auto-flag risky bids. Reps stay empowered to move fast, without unknowingly quoting below profitability. These built-in protections maintain pricing discipline, prevent margin erosion, and build long-term pricing confidence across your team.

Dynamic quoting workflows boost speed and accuracy

Customize templates with built-in pricing logic and automatic approvals. Quotes go out faster, look cleaner, and require less back-and-forth. This removes bottlenecks in the quoting process and ensures consistency, helping your team spend more time closing deals and less time formatting quotes.

Win/loss analytics surface quote trends and rep performance

Track which quotes are converting, where you're losing, and why. Get visibility into performance by customer, region, or rep—so you can improve win rates over time. These insights let you fine-tune pricing strategies, coach sales reps more effectively, and prioritize the most profitable opportunities.

Easy integration with dispatch

Once approved, quotes flow directly into dispatch as tickets. This seamless handoff ensures the quote details move straight into dispatch without the need for re-entry or back-and-forth between teams. That means fewer mistakes, faster ticket generation, and better alignment between sales and delivery operations.

Forecasting tools that drive smarter pricing and planning

Slabstack’s forecasting dashboard breaks down quoting activity by region, product, and customer type, so you can adjust pricing, prep your plants, and align sales and ops before demand hits. This predictive view empowers you to make data-driven decisions, reducing the risk of overproduction or stockouts.

Here’s what John Malcolm, Vice President at Carew Concrete, has to say about using Slabstack:

“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.” 

If you’re tired of quoting based on guesswork and seeing it cost you deals or erode your margins, it’s time to fix the internal processes behind your pricing.
