What is Sales & Operations Planning? A Guide to Smarter Business Strategies

Imagine this.

Your sales team just landed a massive deal—one that could catapult your business to the next level.

There’s just one problem. No one checked with operations. The warehouse is low on stock, suppliers are backlogged for weeks, and production is already at capacity.

Now, instead of celebrating, your team is scrambling to manage delays, angry customers, and a nightmare of last-minute firefighting.

Sound familiar?

This is exactly why sales and operations planning (S&OP) exists. In this guide, we explain why S&OP is mission-critical for modern businesses, how to implement it effectively, and how the right technology—like a stock-aware CRM system—can supercharge the process.

What is Sales & Operations Planning (S&OP)?

Sales and operations planning (S&OP) is a cross-functional planning process that aligns demand (sales forecasts, customer orders) with supply (inventory, production capacity).

The goal of S&OP is to ensure that warehouses don’t overflow with unsold products and that sales and operations processes stay efficient.

When done right, S&OP is a powerful strategic weapon. It reduces costs, improves efficiency, and keeps customers happy. Here’s how:

• Streamlines processes: S&OP standardises planning cycles—this could be monthly or quarterly reviews—which ensures adjustments are made in real-time. It encourages cross-functional collaboration, requiring sales, supply chain, and finance to share data and make decisions together.
• Improves demand forecasts: S&OP allows you to make more informed demand forecasts to prevent overstocking and understocking. If you onboard an AI-powered planning tool as part of your S&OP, you can say goodbye to traditional spreadsheets and use machine learning models that use real-time data to make smarter inventory decisions.
• Helps optimise resource allocation: S&OP ensures resources, whether it’s raw materials, labour, or capital, are used efficiently. For example, as part of S&OP, the manufacturing department might adjust capacity dynamically to minimise idle time, the supply chain team may order materials based on actual demand rather than hunches, and the finance department might avoid unnecessary expenses to optimise cash flow.

Why Do Businesses Use Sales & Operations Planning?

Businesses use S&OP because without it, sales, production, and finance operate like rival factions instead of a unified team. Sales wants to push as much product as possible, production struggles to keep up, and finance worries about costs.

S&OP brings them all to the same table and ensures decisions are data-driven, not gut-driven.

A well-structured S&OP process prevents stockouts (and, by the same token, lost sales) and overstocking (which translates to higher carrying costs) by aligning demand forecasts with production capacity and supply chain capabilities.

A CRM is at the heart of S&OP. It integrates with other systems in your tech stack to help you make smarter decisions about inventory, pricing, procurement, and more.

Let’s look at the primary reasons a business uses S&OP and how integrating CRM with your inventory, accounting, and marketing systems helps get the job done more effectively.

Aligning Sales & Marketing

Sales and marketing often run in opposite directions. Sales wants to push what’s available, while marketing is busy promoting what “should” sell. S&OP forces them to align by ensuring marketing campaigns actually support realistic targets and available inventory.

Integrating your CRM with your inventory and marketing systems can provide sales and marketing with common ground to put effort into. Here’s how:

• Better demand forecasts: Demand forecasts tell sales what to push and marketing what to promote. The CRM pulls real-time data on customer trends, purchase history, and campaign effectiveness from your marketing system, which helps make sales forecasts based on actual demand signals and not guesswork.
• Personalised promotions: With real-time inventory and sales data, marketing can create campaigns that push products that are in stock. This prevents the dreadful “sold out” notice right after running an expensive promotion. 
• Closed-loop feedback: CRM sales data feeds back into marketing, allowing quick pivots when products underperform or demand spikes unexpectedly.

Integrating Inventory Management

S&OP is fundamentally about balancing supply and demand. Without real-time inventory visibility, you risk overstocking slow-moving products or running out of bestsellers at the worst time.

Integrating your CRM and inventory system has the following benefits:

• Stock-aware selling: A CRM that syncs with inventory ensures sales reps only sell what’s available. You no longer have to face those embarrassing “we just ran out” moments.
• Data-driven demand planning: Analysing past sales data and upcoming forecasts helps inventory teams optimise stock levels and distribution strategies, underpinning your S&OP efforts.

The Role of Accounting and Finance

Sales wants to sell, operations wants to deliver, but finance wants to make sure it’s all actually profitable.

S&OP bridges the gap between your company’s revenue ambitions and financial reality. It ensures decisions are backed by hard numbers instead of aggressive sales targets.

To achieve their goal, the finance team needs access to concrete data, and that’s why integrating your CRM with accounting software or ERP is critical. Here’s how it helps:

• Real-time cash flow visibility: A CRM integrated with accounting tools helps finance track incoming revenue, pending invoices, and overall financial health. This ensures that S&OP decisions don’t overlook cash flow constraints.
• Profitability analysis: Real-time data helps the finance team determine which products and customers are actually driving profit. Sales can look at this information to focus on profitable SKUs instead of chasing low-margin deals.
• Budget-driving planning: Finance can set realistic budgets for inventory procurement, marketing spend, and sales incentives based on historical sales trends and projected cash flow.

The Core Components of a Successful S&OP Process

The best companies treat S&OP as a data-driven, cross-functional strategy that ensures demand, supply, and financial planning are in sync. To help you achieve this goal, we walk you through the various stages of the S&OP process and its core components below.

• Product review: This is where you evaluate what’s selling and what’s not and whether new product launches, retirements, or updates will impact the supply chain. It’s also the stage where you identify constraints, such as a chip shortage throwing a curveball in electronics production or a supplier hiking process.
  
  Pro tip: If your CRM is integrated with inventory and sales data, it can help you track product lifecycle trends and identify which products need aggressive promotion and which should be phased out.
• Demand planning: This is where sales, marketing, and finance come together to predict customer demand. Historical sales data, market trends, seasonality, and competitor analysis are fed into a forecasting model to get a reasonable idea of future demand.
• Supply planning: Once your demand forecast is locked in, operations and supply chain teams will ask the million-dollar question—can we actually deliver what sales is promising? This is the stage where you check that raw materials, production schedules, warehouse capacity, and supplier contracts all match demand expectations.
• Financial reconciliation: A demand and supply plan looks great until finance asks, "How do we pay for this?" This is where you verify that supply chain costs are under control and the business isn’t committing to something financially unrealistic.
• Executive S&OP meeting: This is the moment of truth. The CEO, CFO, and senior leaders review the consolidated S&OP plan, challenge assumptions, and either approve or send it back for adjustments. This is the stage where decisions about inventory, investments, pricing strategies, and supply chain risk mitigation are finalised.

Challenges in Sales and Operations Planning (& How to Overcome Them)

You’ll likely come across various challenges during S&OP. While most challenges are company-specific, here are three key challenges commonly experienced by most companies:

Siloed Data & Poor Communication

When your sales, operations, and finance systems aren’t integrated, you’re left with siloed data and systems that can’t communicate with each other.

Translation? Your processes are riddled with problems such as frequent duplication of effort, decisions made in a vacuum, and compromised data integrity.

It’s like trying to run a relay race while blindfolded. No one knows when to pass the baton.

To overcome this problem:

• Integrate your systems: A CRM integrated with inventory, sales, and financial data ensures everyone works from the same playbook. No more guessing what’s in stock or what customers are actually ordering.
• Adopt real-time dashboards: Use a centralised dashboard that updates forecasts, sales trends, and stock levels in real time. This eliminates outdated reports and messy spreadsheets, making your process error-free and more efficient.

Inaccurate Demand Forecasting

Inaccurate demand forecasts can lead to two disasters: overstocking (which leads to higher carrying costs and cash flow problems) and stockouts (which lead to angry customers and lost sales).

To improve the accuracy of your demand forecasts:

• Integrate CRM with sales and inventory data: A CRM that pulls live sales trends and inventory levels helps you predict demand based on real customer behaviour in addition to historical sales data.
• Use AI and machine learning: AI-powered forecasting tools analyse historical sales, customer trends, and external factors (like seasonality or economic shifts) to give you more accurate demand predictions.
• Run “what-if” simulations: Let’s face it. Forecasting demand accurately is tough. You can be reasonably accurate at best, but it’s nearly impossible to be spot on. That’s why you need to run “what-if” simulations and test your business for sudden spikes in demand, delayed shipments from suppliers, and other unexpected scenarios.

Resistance to Change

People hate change, especially if they think it makes their job harder. If teams don’t see value in S&OP, they’ll resist new processes and stick to old-school spreadsheets.

One of the best solutions to help make change easier is to use the right tools, such as CRM. 83% of employees experiencing change fatigue lack the necessary tools and resources to adapt, leaving them unprepared and underwhelmed.

Here’s what you can do to remedy this:

• Show quick wins: To prove the benefits of S&OP, start with small, high-impact improvements (such as automated stock updates) instead of a massive overhaul.
• Get leadership buy-in: Teams are more likely to follow suit if executives actively push S&OP adoption.
• Make training a priority: Invest in S&OP training and explain how automation and integration actually make jobs easier, not harder.

Benefits of Implementing Sales and Operations Planning

For all that effort you put into S&OP, you get multiple benefits that make your time and money investment ROI-positive. Let’s dive deeper into the benefits you can expect from S&OP.

Improves Forecast Accuracy

Wrong forecasts can have plenty of downsides. They can lead to stockouts, excess inventory, and missed revenue opportunities. S&OP helps improve forecast accuracy by combining historical and current sales data and market intelligence. This minimises stockouts and keeps working capital free for other purposes.

Picture this. You’re a B2B distributor of industrial components. Without S&OP, you might not know how many parts to order. You either order too much to play it safe and end up tying cash in slow-moving stock or order too little and end up with a stockout.

However, if you’ve integrated your CRM with all systems in your stack, it can track customer orders and upcoming deals and adjust demand forecasts. This gives you a data-backed order quantity that allows you to strike a balance between costs and the risk of stockout.

Cost Efficiency

Some of the most pressing challenges for B2B businesses are related to costs. Think excess inventory, emergency shipping costs, and inefficient resource allocation. All of these eat into your profit margins.

S&OP aligns supply with demand, which helps reduce unnecessary spending, optimise procurement, and prevent last-minute supply chain disasters.

Moreover, when inventory systems and accounting platforms are linked to S&OP, finance teams get clearer visibility into cash flow and costs.

For instance, if you’re a manufacturer using S&OP, you can spot seasonal demand trends early. This enables you to place bulk orders at lower costs rather than resorting to expensive, expedited shipping when demand spikes unexpectedly.

Cross-Department Collaboration

Operating in silos is a recipe for disaster. Sales pushes aggressive targets, operations scrambles to keep up, and finance fights cost control. Everyone’s making an effort in different directions and finding it hard to get anywhere.

S&OP forces teams to align through a unified planning process. This ensures sales doesn’t overpromise, operations doesn’t get blindsided, and finance doesn’t get caught off guard by unexpected costs.

Think about a B2B hardware distributor, for example. They supply construction companies with materials like fasteners, adhesives, and power tools.

As summer approaches, their S&OP process reveals a sharp increase in orders for concrete anchors. The procurement team spots this trend and secures bulk pricing from suppliers before demand peaks, while the warehouse team optimises storage to handle the influx.

At the same time, the sales team adjusts its strategy to prioritise outreach to contractors working on new highway projects. The result? Smooth operations, a competitive edge, and greater profitability.

However, getting this right might have been difficult (or even impossible) if the company hadn’t paid attention to S&OP.

Stronger Business Agility

Supply chain disruptions, sudden demand shifts, or economic changes can derail the best business plans. S&OP gives your company the agility to respond proactively instead of reactively in the face of a disruption.

When you have a real-time view of sales, inventory, and cash flow, you’re in a better position to pivot strategies without panic, whether that involves adjusting production, reallocating resources, or changing your pricing.

For example, if one of your major suppliers experiences production delays, S&OP ensures you’re notified well before it turns into a bigger problem. This notice is also a cue for you to look at alternative suppliers and see if any of them can meet your current demand with their standard lead time before the situation worsens.
