Ranjan Mendonsa California is a San Ramon, California-based finance executive who has spent nearly four decades working across the technology, payments, retail, and consumer packaged goods industries. Since 2013, Mendonsa has served Visa in Foster City, first as senior director of technology finance and now as vice president of finance, where he oversees more than $1.6 billion in annual operating expenses and roughly $600 million in capital budgets spanning hardware, software, real estate, and aviation. He has led global budgeting, forecasting, and reporting processes, played a central role in integrating the newly acquired Visa Europe business, and partnered with cross-functional teams to identify multi-million-dollar cost savings with technology vendors and telecommunications carriers. That cross-industry financial background, including years spent in retail finance, informs a practical understanding of how businesses can better identify and serve the customers who matter most to their bottom line.
A retailer can weaken decisions by trying to appeal to every shopper. Without a clear customer focus, managers must juggle too many signals when they choose products, set prices, plan promotions, stock inventory, and make service promises.
Retailers make stronger decisions when they know which customers they can serve well, repeatedly, and with enough margin to support the business.
Customer segmentation means grouping customers by shared traits, needs, behaviors, or buying patterns. The customers a retailer serves best are the groups whose needs, habits, service expectations, and revenue patterns fit the store’s model.
A retailer might look at budget shoppers, convenience shoppers, repeat buyers, gift buyers, or customers who want a product category. The point is not to label people, but to connect customer groups with business decisions.
Retail owners and store managers can start by reviewing measurable customer behavior. Repeat purchases, steady category demand, larger purchases, lower return rates, loyalty activity, and product feedback can show which customers support the store most consistently.
Those patterns help the business separate useful demand from occasional sales that should not define the store’s main direction.
Retailers should use customer knowledge to guide assortment planning. A convenience-focused store may need dependable everyday items across a narrow set of categories, while a specialty retailer may need deeper selection in fewer areas.
Merchandising teams can build more practical assortments when they know which products matter most to customers that the store can serve reliably.
Pricing and promotions need a separate test. A discount may increase traffic, but retail managers still need to know whether the offer attracts repeat buyers, protects gross margin, or only moves product for less money.
They should judge promotional success by customer response, margin, and long-term fit, not only by transaction count.
Inventory decisions carry their own risk. Too much inventory can tie up cash, create waste, force discounts, and crowd out stronger products, while too little inventory can cost sales and frustrate loyal shoppers.
Store managers and inventory teams should use demand patterns to decide how much product to carry, when to reorder, and when a product no longer deserves the same space.
Simple measures can help retailers test whether their customer assumptions hold up. Retailers can track repeat purchases, average transaction value, long-term customer value, product returns, promotion response, complaints, and margin by product group.
They should connect those measures to the customer groups they chose to serve. Tracking them across weeks or seasons can show whether demand remains strong or whether customer behavior has shifted.
Competitor review can add context, but it should not turn into copying. Retail managers can study what nearby or online competitors sell, how they price, which customers they appear to serve, and where they seem stronger or weaker.
Retailers can use that review to understand their market position instead of reacting to every competitor move.
Serving the wrong customer can create problems beyond a single sale. A retailer may add too many product lines, complicate return policies, stretch customer support, or create a store experience that regular shoppers no longer understand.
Those choices can make daily operations harder, even when sales activity appears busy.
The practical test comes when the retailer faces its next tradeoff. If a product line, discount, display, or service promise mainly serves customers outside the store’s best fit, the owner or team has a clear reason to question the choice before committing more space or money.
That habit keeps shelf space, staff attention, and marketing dollars tied to customers the business can support consistently.
