Wholesale Distributors: Working Capital Is the Whole Game

The time it takes to convert cash spent on inventory back into cash collected from a customer, inventory days plus receivable days minus payable days, tells you how much working capital the business actually needs to fund its sales volume. A distributor who has never calculated this number for their own business is usually surprised by how large it is, and it's the single most useful number for understanding why growing sales can strain cash even while the business stays profitable on paper.

Suppliers often offer volume-based rebates or early payment discounts, and a distributor buying from many suppliers on different terms needs someone reconciling actual rebate income against purchase volume supplier by supplier, not assuming it all nets out. A controller who tracks this catches money the business is owed but hasn't claimed, and also catches a supplier relationship where terms have quietly gotten worse compared to a competitor's terms on similar volume.

Business customers on trade credit terms don't always pay on schedule, and a distributor extending generous terms to win volume needs to weigh that against the real cost of carrying those receivables, financed either by the distributor's own cash or a line of credit. A controller tracking receivables aging by customer, and flagging any account sliding past its terms, protects cash flow directly, while a fractional CFO decides whether the terms being offered across the customer base actually make sense given the business's own cost of capital.

Say the distributor wants a line of credit to support inventory ahead of a seasonal demand spike. A lender will price that against the prime rate, currently 6.75%, plus its own margin, and will want to understand the business's cash conversion cycle before extending credit against inventory and receivables¹. A controller produces the clean financials and aging reports the lender needs. A fractional CFO decides how much financing the growth actually requires and negotiates terms that fit the business's real seasonal pattern rather than a generic credit facility.

The national median salary for accountants and auditors is $83,680 a year, a meaningful fixed cost for a distributor still working with a lean back office². A smaller distributor with straightforward supplier and customer relationships might get by with a fractional CFO reviewing the cash conversion cycle quarterly and outsourced bookkeeping handling the rest. A distributor running significant inventory across multiple suppliers and extending trade credit to many customers usually needs a dedicated controller managing that daily, since small errors here compound directly into cash the business can't access when it needs it.

Say the distributor lands a major new customer that doubles order volume overnight. More volume means more inventory to carry and more receivables outstanding at any given moment, even if the new customer pays exactly on terms, which means the working capital need grows right along with the win everyone is celebrating. A controller who flags that the cash conversion cycle now requires meaningfully more financing than before catches the problem while there's still time to arrange it, rather than after the business has already committed to fulfilling orders it doesn't have the working capital to support comfortably.

Distribution often runs on thin per-unit margin made up in volume, and a single product line with a razor-thin margin can look fine in a blended company average while actually losing money once true carrying cost of its inventory and the labor to pick, pack and ship it are fully allocated. A controller who breaks out margin by product line, not just by customer or by month, is often the first person in the business to notice that a high-volume line everyone assumes is profitable is actually being subsidized by a handful of higher-margin lines carrying the company average the whole time.

A controller supporting a distributor should be able to report on these items:

• The cash conversion cycle, calculated as inventory days plus receivable days minus payable days, so the true working capital need is known.
• Rebate income and early payment discounts reconciled against purchase volume, supplier by supplier, instead of assuming they net out.
• Receivables aging by customer, with slow payers flagged before generous terms turn into a real financing cost.
• Margin by product line, including inventory carrying cost and the labor to pick, pack and ship each item.
• The added working capital a new large customer will require, since more volume means more inventory and receivables outstanding.
