Improving the cost structure of commercial management means reducing what it costs to sell to and serve each customer without deteriorating service. It is achieved by measuring the cost to serve by segment, redesigning the service model, eliminating rework in the order cycle and moving the repetitive transactions that today keep salespeople busy to digital channels.
For senior leadership, commercial cost is usually an aggregate figure on the income statement: salesperson salaries, commissions, travel expenses, materials, customer service. That view hides what matters most. Two customers who bill the same amount can leave very different margins depending on how many visits they demand, how many small orders they place, how many invoices are corrected and how many returns they generate. Whoever does not know their cost to serve ends up subsidizing the least profitable customers with the margin of the best ones, and competing on price without knowing how much they can concede.
The commercial cost structure is the set of resources the company consumes to generate and sustain sales: the field and telephone sales force, order taking and entry, quote management, after-sales support, collections, commercial materials and the technology that supports all of the above. In general terms, cost is what is spent to manufacture a product or to provide a service, and the great challenge for companies is to reduce it so that it becomes a competitive advantage: being able to offer a lower price than the competition and keep making money, without harming customer service. Unlike production cost, which is associated with the product, commercial cost depends above all on the customer and on the way they are served.
That is why the key concept is the cost to serve: how much it really costs to serve a customer or a segment over a period, including all the commercial and service activities it demands. When that cost is compared with the gross margin the customer generates, the real profitability of the portfolio appears, which is often very different from what sales volume suggests.
Companies that sell to other businesses face a bigger challenge than those that sell to end consumers. Their customers buy frequently, negotiate particular terms, demand accuracy in prices and deliveries, and are very sensitive to both price and service. When that whole relationship depends on salespeople, every transaction carries costs that nobody sees in full.
This last point weighs the most on the cost structure. As we explained in the article What is a B2B eCommerce store and why is it important for your company to sell 24x7?, "it is clear that the capacity to serve customers in the traditional way is very limited." A model in which the company depends 100% on its salespeople to manage customers can hardly reduce commercial cost and, at the same time, increase average billing per customer.
You cannot improve what you do not measure, and traditional accounting systems allocate commercial expenses with criteria that are too coarse, such as a percentage of sales. The result is that small, complex customers look profitable and large, simple ones look expensive.
A practical alternative is time-driven activity-based costing, known as TDABC. Robert Kaplan and Steven Anderson presented it in Harvard Business Review as a way to estimate the resources each transaction, product or customer consumes with only two parameters: the cost per unit of time of the available capacity and the time each activity requires. According to the authors, the model delivers cost and profitability information quickly and inexpensively, and exposes inefficient processes, unprofitable products and customers, and excess capacity.
Applied to commercial management, the exercise consists of:
The result is a profitability map by customer and by segment that changes the commercial conversation: it is no longer about selling more at any cost, but about deciding how to serve each customer according to the value they generate.
Sustainable cost reduction rarely comes from across-the-board cuts. It comes from three levers that reinforce one another: improving processes, relying on technology and allocating resources better. Technological innovation applies to processes as well as to products and services. On top of that comes a cultural component: involving most of the staff in cost reduction. When the team understands how much each activity costs and takes part in looking for alternatives, efficiency becomes a habit and not a campaign.
In practice, the measures with the greatest impact are usually these:
Processes and technological innovation are the very heart of B2B eCommerce, and that is why it is one of the best alternatives for reducing costs, improving processes and increasing average billing per customer. It directly attacks the two factors that make commercial management most expensive: manual processes and limited capacity. And it does so at a time when buyers have already changed the way they buy.
The McKinsey study "Five fundamental truths: How B2B winners keep growing", published in September 2024, found that B2B customers use an average of ten interaction channels in their buying process, that about a third prefer digital self-service options and that, among the surveyed companies that offer eCommerce, online sales already represent 34% of revenue. Years earlier, Gartner warned that 33% of buyers wanted a purchasing experience without a salesperson.
The following table summarizes how each component of commercial cost changes when the digital channel is designed correctly.
| Cost component | Traditional model | With a well-designed B2B eCommerce store |
|---|---|---|
| Order taking | Salesperson and data-entry clerk take part in every order | The customer places the order, which reaches the ERP validated |
| Errors | Manual transcription of SKUs, prices and terms | Catalog and prices by customer applied automatically |
| After-sales support | Calls for order status, invoices and returns | Self-service for inquiries, invoices and history |
| Commercial materials | Printed catalogs and lists that become outdated | Up-to-date digital catalog with alternatives and related products |
| Sales capacity | Limited by each salesperson's hours | Available at all hours, the salesperson focuses on growing accounts |
An important warning: the digital channel does not reduce costs on its own. If prices are not organized, the catalog is incomplete or the integration with the ERP is weak, the portal generates more manual work than it eliminates. Technology accelerates a process; it does not fix a poorly designed one.
ICX Consulting is a commercial strategy and customer experience firm headquartered in Miami that supports companies in the United States and Latin America. Our activity-based cost management practice measures the real cost of serving each customer, and with the PCR methodology we connect costs, prices and profitability in a single diagnostic. On that basis we redesign the service model and, when the business justifies it, we implement the B2B eCommerce channel integrated with your ERP and your CRM.
To take the first step, we invite you to use the ICX activity-based costing toolkit, which will help you identify the commercial activities that consume the most resources in your company.
Reducing costs usually implies across-the-board cuts that can affect service and sales. Improving the cost structure means changing how resources are consumed: which activities are eliminated, which are automated and how attention is allocated according to the profitability of each customer. The goal is to sell and serve better at the same or lower cost.
In addition to gross margin per customer, useful indicators are the commercial cost per order, the proportion of orders and invoices that require correction, the average time from request to order confirmation and the share of the digital channel in recurring purchases. Reviewed every month by segment, they show whether the new service model really frees up capacity.
No. Its role is to absorb repetitive transactions so that salespeople can concentrate on opening accounts, developing strategic customers and negotiating. For it to work, it is advisable to adjust the compensation rules so that the salesperson promotes the digital channel among their customers instead of seeing it as competition.
A cost-to-serve diagnostic on a representative sample can be completed in a few weeks and usually reveals immediate opportunities in prices, minimum orders and service rules. The savings from a digital channel arrive gradually, as customers adopt self-service and manual processes are retired.
A healthy commercial cost structure allows you to compete with sustainable prices, serve better the customers who generate the most value and grow without multiplying the payroll. If you identify with these challenges in your company, analyzing the B2B eCommerce model may be the key to improving your cost structure.
