ROI calculations in B2B e-commerce often fall short because they fail to capture the full complexity of multi-channel buying behavior. The debate centers on whether companies should keep metrics simple to drive action or build comprehensive models that account for field sales influence, customer lifetime value, and cross-channel attribution.
The ROI calculation challenge
Standard e-commerce ROI uses a simple formula: revenue equals sessions times web conversion rate times average order value. On the cost side, companies typically allocate technology at about 60%, people at 25%, and administration at 15%. Many argue this basic approach is sufficient.
However, B2B e-commerce involves field operations, telesales, and customer support that all influence website metrics. A more comprehensive model factors these capabilities into both revenue and cost calculations. The question is whether the additional complexity is worth the effort.
The debate format
Team Keep It Simple featured Michael Eichinger from Bay Fastening Systems and Megan Stabler from BigCommerce. Team Measure Everything included Marta Dalton from Unilever and Steven Javor from Schneider Electric. All brought experience implementing ROI frameworks in complex B2B environments.
Round 1: Defining critical ROI measures
Megan Stabler argued for simplicity: number of customers, number of orders, average order value, and channel attribution. She cited LinkedIn research showing 58% of digital marketers must prove ROI before getting funding, which slows momentum. The same research found 78% measure customer lifetime value within the first month, but only 4% continue measuring at six months. Starting with a few metrics and expanding later makes more sense.
Keep it simple, keep it short, keep it quick, and start measuring from there. If you want to deliver all of that food at the same time to the table for a sitdown menu, you have got to practice and take short steps.

Michael Eichinger reinforced that digital transformation alters every part of the business. Focusing on how well the company is transforming, measuring the transition from traditional to digital, matters more than detailed attribution in the early stages.
Marta Dalton countered that B2B complexity requires deeper measurement. Factors like credit access, stock room size, and industry-specific search terms affect buying behavior. Focusing only on top-level metrics misses the behavioral insights that reveal customer opportunities and weaknesses.
Just like your beauty is not only skin deep, neither is this equation. You have to be able to dig down into it and understand what is happening behind the scenes.

Steven Javor agreed that B2B journeys are more sophisticated than B2C, requiring broader metric understanding. However, he noted that leadership should see a few KPIs rather than drowning in complexity, even if the team tracks more granular data.
On cross-channel attribution, Steven cited that 60% of distributor orders arrive via email purchase orders, yet customers start their journey online. Measuring only shopping cart conversions drastically understates digital influence. One partner shows only 2% e-commerce sales, but removing online SKUs would cause far greater losses.
The audience voted that fewer metrics are needed to measure B2B e-commerce ROI effectively.
Round 2: Revenue and cost considerations
Marta Dalton argued that both lift and shift are required. Calculating lift is simpler than people claim. Without it, executives assume field sales could have achieved the same results. The shopping effect, where customers browse the full catalog and see promotions they would never encounter in a five-minute sales visit, generates real incremental revenue. At Coca-Cola, average website visit time increased from three to five minutes up to nine minutes while conversion rates held steady.
Steven Javor added that data monetization represents an untapped revenue stream. Companies like Home Depot and Amazon sell data back to manufacturers. Every e-commerce solution with traffic volume should explore this opportunity.
Michael Eichinger argued for focusing on retention and stability first during transformation, then expanding metrics later. Customer lifetime value cannot be defined in early digital stages because the landscape and customer base are fundamentally changing.
On costs, Marta emphasized that fixed costs resonate most with executives. B2B e-commerce repurposes salespeople rather than replacing them, enabling one rep to serve 20 to 30% more accounts. Every executive understands that math.
I like to call e-commerce the 24/7 personal assistant doing all the crap your sales team does not want to do. But ultimately, if you are not hiring additional heads and you do not have to, then you are much better managing your fixed costs.
Marta Dalton, Unilever
Steven Javor reinforced that salespeople are no longer order takers. They need to be solutions providers and relationship builders. E-commerce handles the transactional work.
The audience voted that generating incremental revenue is necessary for an acceptable ROI calculation.
Round 3: Timeline and customer lifetime value
Megan Stabler advocated for measuring churn, retention, and upsell rather than complex lifetime value calculations. She cited Bain research showing a 5% increase in customer retention can boost profits by 25% or more. Simple metrics tied to business outcomes beat academic exercises.
Michael Eichinger agreed that retention matters most through transformation. Customer lifetime value cannot be accurately measured when developing a whole new type of customer relationship.
Marta Dalton disagreed. Customer lifetime value is essential for justifying acquisition costs. Field sales visits cost $50 per hour fully loaded. Three or four visits to onboard a customer means hundreds of dollars in acquisition costs. With B2B average order values around $1,000 and margins around 10%, first-year ROI is often negative. Without CLV projections, companies cannot justify the investment.
Steven Javor suggested refining CLV to a cash multiplier over 30, 60, or 90 days, or six months depending on the business. Companies need a time window they can affect and afford.
On planning horizons, Steven emphasized the balance between speed and technical debt. He once spent seven years trying to align executives on an e-commerce business case, missing huge opportunity costs. But rushing creates technical debt that can double remediation costs later.
Marta reinforced the technical debt warning with an example of a hybrid installation that crashed weekly for two months after launch due to inadequate planning.
Megan closed by arguing that the digital world moves in months, not years. Test and learn, get something running, and iterate. Competitors who start today will pass companies still building business cases.
The audience voted 71% that customer lifetime value is not worth the effort to calculate accurately.
The verdict: Keep it simple wins, but context matters
Team Keep It Simple won two of three rounds. Fewer metrics won round one, and CLV skepticism won round three. Team Measure Everything won the incrementality round.
Four conclusions emerged. First, where a company sits in its digital transformation journey determines appropriate metric complexity. Early-stage companies should focus on transformation success before detailed attribution.
Second, both lift and shift matter for executive credibility. Shift alone looks like treading water. Lift demonstrates forward progress.
Third, a four-bucket framework captures the full ROI picture: revenue lift, revenue shift, profit enhancement, and organizational efficiencies. Companies focusing only on direct web revenue miss operational gains that often exceed direct sales impact.
Fourth, a three-to-five-year vision with a 12-to-18-month operating plan prevents both analysis paralysis and technical debt. The challenge is maintaining urgency while planning adequately. As one panelist noted, you cannot wait for the perfect business case, but you also cannot afford to rebuild a failed implementation.
