eCommerce and Omnichannel: How to Increase Customer Spend

Written by Victor Esquivel | Nov 03, 2026

An omnichannel eCommerce increases customer spend because it connects the digital store, salespeople, service and physical channels into a single relationship. The customer buys when and where they prefer, the company knows their full history and can recommend, replenish and personalize at every contact, which raises the frequency and value of each order.

Many companies have already learned that maintaining the status quo translates into stagnant growth, spiraling operating costs and loss of market share. For senior leadership, omnichannel is not a technology project. It is a decision about how revenue per customer grows without commercial cost growing in the same proportion. A sales model that depends only on the capacity of the field team has a ceiling. A well-designed omnichannel eCommerce raises that ceiling, protects margin with better pricing rules and reduces the cost to serve, because repetitive tasks move to a channel available 24 hours a day. This article explains what omnichannel really means in eCommerce, why it increases customer spend, what capabilities the platform needs and how to prioritize the investment.

What is omnichannel in eCommerce?

Omnichannel in eCommerce is the integration of all of a company's sales and service channels (online store, salespeople, contact center, distributors, physical stores, email and messaging) on a single database of customers, products, prices and inventory. The customer can start a purchase in one channel and finish it in another without repeating information, and the company sees a single story of each relationship.

It is worth distinguishing it from two concepts with which it is often confused:

  • Multichannel. The company is present in several channels, but each one operates with its own data, prices and goals. The customer perceives several different companies.
  • Isolated digital channel. There is an online store, but it does not talk to the ERP, the CRM or the sales team. It sells, but it does not learn from the customer or feed the rest of the organization.

The difference is not in the number of channels but in the coherence among them. When price, availability, commercial terms and history are the same at every touchpoint, the customer trusts more and buys with less friction.

eCommerce will not replace traditional commerce, but it is forcing it to change. Just as television and video did not put an end to movie theaters, physical stores and traditional channels will have to be more attractive, more practical and more effective, and omnichannel is the way to achieve that without abandoning what already works.

Why does omnichannel increase customer spend?

The evidence points in the same direction in both consumer goods and business-to-business sales. A study published in Harvard Business Review on 46,000 shoppers concluded that the more channels customers use, the more money they spend. In the B2B world, McKinsey reports in The new B2B growth equation that buyers expect to interact seamlessly across ten or more channels, that all B2B customer segments prefer an omnichannel model and that 72% of B2B companies selling through seven or more channels gained market share. According to Forrester, "customers are motivated to spend more overall when they interact with multiple channels," and the experience of our consultants in B2B digital commerce projects confirms that trend.

Behind those results there are concrete mechanisms that any chief commercial officer can recognize:

  • More buying occasions. The customer does not depend on the salesperson's calendar. They replenish, request a quote or expand their order the moment the need arises, and that need is not lost to a competitor.
  • More complete orders. Recommendations of complementary and substitute products, frequent purchase lists and volume incentives raise the value of each order without sales pressure.
  • Less friction, less abandonment. Seeing inventory, price and delivery date in real time eliminates the wait for a quote, which is one of the moments when the most opportunities go cold.
  • Personalization based on real data. When the platform knows the customer's history across all channels, it can offer what that customer needs and not a generic catalog. In its analysis of the value of personalization, McKinsey estimates that it typically generates a revenue increase of 10% to 15%, and that 71% of consumers expect personalized interactions.
  • More trust and loyalty. A customer who receives the same answer, the same price and the same level of service in every channel has fewer reasons to compare and more reasons to concentrate their spending with a single supplier. Personalization also conveys a sense of professionalism that makes the customer feel special; it is the small, great details that make the difference.

Omnichannel in B2B and B2C: does the strategy change?

The principle is the same, but the application is different. In B2C, omnichannel usually revolves around the buying experience, delivery and repurchase. In B2B it revolves around commercial terms, accounts with several buyers and the coexistence of the digital channel with the account executive.

DimensionB2C omnichannel eCommerceB2B omnichannel eCommerce
Main spending leverPurchase frequency, average ticket, loyalty programsShare of wallet, scheduled repurchase, expansion of lines
PriceList price, promotions and couponsCustomer-specific price lists, volume tiers, contracts and credit
Role of the salespersonAdvice in store or contact centerRelationship management and negotiation, with repetitive orders moved to the digital channel
Critical dataBrowsing behavior and purchase historyHistory by account, quotes, payment terms and reserved inventory
Success indicatorCustomer lifetime value and repurchase rateRevenue per account, margin per customer and cost to serve

In both cases, the costliest mistake is to treat eCommerce as a separate channel with its own goals that compete with those of the sales team. If the salesperson feels that the online store takes sales away, they will push it away from their customers. Compensation and goals must recognize the account's revenue regardless of the channel through which it arrived.

What capabilities does an omnichannel eCommerce platform need?

Few platforms meet everything a serious omnichannel model demands. Before choosing technology, leadership should confirm that the architecture addresses these capabilities:

  • Integration with ERP, CRM, inventory, logistics and payment methods. Without integration there is no omnichannel, only parallel channels. Order, price and stock information must flow in real time or very close to it. Having everything integrated provides full traceability, measurable results and a deeper knowledge of the customer, which translates into a better relationship and more sales.
  • Centralized communication and promotions. A single platform for communicating and promoting strengthens the synergy between offline and online channels. Analytics of the information coming from all channels makes it possible to detect buying patterns, remember dates relevant to each customer and anticipate recurring purchases.
  • Real-time quoting and availability. The customer must see inventory, applicable price and delivery dates without waiting for a salesperson to send the information.
  • Catalog and pricing management by segment. Customer-specific price lists, discount rules, volume tiers and promotions that apply consistently across all channels.
  • Buying convenience. 24x7 purchasing, frequent product lists, quick order by code and one-click repurchase.
  • Navigation and search. It is easier to find products on a site designed to explore, filter and discover than in a PDF catalog.
  • Recommendations, substitutes and add-ons. The ability to propose cross-sales and higher-value sales at the right moment.
  • Personalized offers. Free shipping, volume discounts or other incentives based on what the customer buys and their value to the company.
  • Service and after-sales in the same view. Order tracking, returns and service cases connected to the customer's history, so that anyone who serves them has the full context.
  • Unified analytics. A single dashboard that shows revenue, margin and behavior by customer and by channel, not one report per system.

Platforms such as Adobe Commerce, successor to Magento Commerce, offer native capabilities for B2B and B2C, and CRMs such as HubSpot or Salesforce make it possible to connect the commercial relationship with the digital channel. Technology, however, only amplifies the model the company designs. If pricing rules, order processes and responsibilities among channels are not clear, the platform will reproduce the disorder at greater speed.

How to measure whether omnichannel really increases spend

An omnichannel initiative must be justified with business indicators, not traffic metrics. The indicators we recommend tracking from the first quarter are:

  • Revenue per active customer, comparing customers who buy through a single channel with those who use several.
  • Purchase frequency and time between orders, especially for replenishment products.
  • Average order value and share of recommended or complementary products.
  • Margin per customer and per channel, to confirm that growth is not being bought with discounts.
  • Cost to serve, measured as the commercial and operating cost per order in each channel.
  • Retention and repurchase, which show whether the experience is building loyalty or merely shifting purchases from one channel to another.

The key point is the comparison between groups of customers. If omnichannel customers spend more but were already the largest before the project, the conclusion is different. That is why it makes sense to define a baseline before launch.

What this means for senior leadership

Omnichannel touches almost the entire customer value chain. These are the decisions that fall to general and commercial leadership:

  • Attract. Make the catalog, prices and availability findable online. Many buyers do their research before talking to a salesperson, and whoever does not appear at that stage does not make the shortlist.
  • Convert. Eliminate the wait for quotes on standard products. Reserve the sales team for complex negotiations and new accounts.
  • Retain. Use purchase history to anticipate replenishment and to detect in time the customers who reduce their frequency.
  • Build loyalty. Design benefits that reward concentrating spend, such as terms based on accumulated volume or exclusive services for recurring customers.
  • Serve. Unify service and after-sales with sales. A poorly handled complaint in one channel erases the value created in the others.
  • Efficiency. Move repetitive orders and status inquiries to the digital channel. This lowers the cost to serve and gives the sales team time to sell.

Roadmap: five steps to start next week

  1. Map the real customer journey. Document how your most valuable customers buy today, which channels they go through and where they stop. This is where the frictions that cost you the most spend appear.
  2. Segment the portfolio by potential. Identify which customers and products concentrate revenue and margin. Omnichannel should start where the impact is greatest.
  3. Define single commercial rules. Price, discounts, credit and availability must be the same in all channels. This is a business decision before it is a systems decision.
  4. Align goals and compensation. Recognize the account's revenue regardless of the channel, so that the sales team drives the digital channel instead of competing with it.
  5. Launch in phases and measure. Start with a group of customers and a limited catalog, establish the baseline and expand only when the spend, margin and cost-to-serve indicators justify it.

For the first step, use our customer journey toolkit and map the moments when your company wins or loses the next order.

Frequently asked questions

Which area should lead an omnichannel eCommerce project?

It should be led by the commercial function, with direct participation from finance, operations and technology. If the project is left solely in the hands of IT or marketing, it tends to become just another channel with its own objectives. An executive sponsor with authority over pricing, processes and compensation is what allows all channels to operate under the same rules.

Does an omnichannel eCommerce replace the sales team?

No. It changes its focus. Repetitive orders, inventory inquiries and shipment status move to the digital channel, and the sales team devotes more time to new accounts, complex negotiations and growth within current customers. For it to work, goals must recognize the account's revenue regardless of the channel.

How long does it take to see results from an omnichannel strategy?

It depends on the starting point, above all the quality of the data and the level of integration with the ERP. A phased launch, with a group of customers and a limited catalog, makes it possible to measure purchase frequency, order value and cost to serve in a few buying cycles and to decide with evidence whether it makes sense to expand.

Which platform suits an omnichannel eCommerce?

The platform should be chosen after defining the commercial model, not before. The key criteria are the ability to integrate with ERP and CRM, handling of customer-specific pricing, support for B2B or B2C depending on your business and scalability. Adobe Commerce, connected to a CRM such as HubSpot or Salesforce, is a frequent option.

If your company sells through several channels but the customer still perceives several different companies, there is revenue waiting to be captured.
