Before dropping a product line, calculate what costs will disappear

A product line can show a loss after allocated company overhead while still contributing cash toward costs the business must pay. Before discontinuing it, calculate the revenue and costs that would actually change. Then include the cash needed to exit and any effect on other products. The decision concerns the whole business after closure, not just a cleaner-looking product report.

ACCA's relevant-cost material illustrates closure and sourcing decisions using changed future cash flows. Its related cash-flow guidance also recognizes opportunity cost when a decision displaces another use of resources. Apply those principles to the line's actual contracts, people, equipment, and customers. A percentage allocation in the accounts is not evidence that a cost can be removed.

Start with net revenue after the relevant discounts, returns, and allowances. Identify the variable costs associated with those sales, including production or purchase cost, payment charges, fulfillment, and support where genuinely variable. Review cost behavior with operations. Some costs change only at a capacity threshold or after a supplier commitment expires.

Separate fixed costs dedicated to the line from overhead shared with the rest of the company. For each dedicated cost, name the action that would remove it and its earliest effective date. Keep a separate record for costs that remain. Reallocating a building lease or shared manager's salary to other products changes the reporting presentation without creating a company saving.

Assume a hypothetical product line has $500,000 of annual revenue, $320,000 of variable costs, $120,000 of fixed costs that would disappear, and $100,000 of allocated overhead that would continue. The product report shows a $40,000 loss. Yet closure would remove $180,000 of contribution while saving only $120,000 of fixed costs, reducing company profit by $60,000 before other changes.

If a further $35,000 of exit cash is required, the first-year cash effect could be worse still, subject to timing and other working capital changes. These are illustrative assumptions, not a recommendation to keep a particular product. They show why the overhead allocation and the company's actual avoidable spending must be distinguished.

List supplier cancellation charges, minimum purchases, customer refunds, warranty support, employee-related costs, disposal costs, and remaining system or premises commitments as applicable. Obtain legal and specialist advice where obligations depend on contract or employment law. Use supported amounts and dates. Label uncertain estimates and keep them separate from obligations already confirmed.

Build an inventory and receivables run-off plan. Some stock may sell through at reduced margin, require support after sale, be returned to a supplier, or have little recoverable value. Outstanding invoices may remain collectible after new sales stop. Preserve the team and records needed to resolve returns, credits, and collections rather than assuming the product code can be closed immediately.

A product may support sales of another product, satisfy a bundled contract, or help retain a customer. Investigate those relationships through actual orders and agreements. Do not assign all related revenue to the discontinued line, but do not ignore a supported effect either. Build a separate scenario for the uncertain customer response and state what evidence would improve it.

If closure frees scarce capacity, identify the alternative use and its additional contribution after incremental costs. Confirm demand, implementation work, and the true bottleneck. A machine or team that becomes idle has not automatically created an economic benefit. Compare the exit with alternatives such as repricing, narrowing the range, changing minimum orders, or outsourcing part of delivery.

Present the company-level financial effect, cash schedule, contractual dependencies, and reasons for the decision. A line may need to close despite positive contribution because of strategy, safety, compliance, or another substantiated constraint. State that reason directly instead of manipulating allocations to make the financial case say something it does not.

Assign owners for the final sale date, customer communication, inventory disposition, supplier settlement, support obligations, and record retention. After the exit, compare realized savings and remaining costs with the approved case. Keep unresolved balances visible until they are settled or appropriately reviewed, so a discontinued product does not leave an unexplained accounting backlog.
