Why Working Capital Beats Cutting Costs

Owners often chase profitability by cutting expenses when the real cash lever is working capital — money already earned but stuck in receivables, inventory, or unfavorable payables terms.
Reducing your cash conversion cycle by 15 days on a $5M revenue business releases roughly $200,000 in cash — permanently, not once.
Working capital freed up is cheaper than any external financing you could raise. It costs nothing but process discipline.
The cash conversion cycle formula: Days Inventory Outstanding + Days Sales Outstanding − Days Payables Outstanding. Every day matters.

Accelerating AR Collections

Invoice the day the work is delivered — not weekly, not at month-end. Every day of delay is a day added to DSO.
Move net-30 clients toward net-15 or credit-card-on-file. For long-standing customers, small terms concessions rarely trigger pushback.
Set up automated dunning at day 30, day 45, and day 60 with escalating tone. Manual follow-up is the biggest source of aged AR.
For repeat customers, require ACH autopay or card-on-file after the first invoice. Payment friction is a collection cost.
Track DSO monthly by customer segment — one big slow-paying customer often accounts for most of the pain.

Extending AP Without Damaging Relationships

Pay every vendor invoice on the agreed terms — but not one day early unless you get a documented discount for it.
Move vendor payments to a scheduled twice-monthly cycle instead of paying invoices as they arrive.
Negotiate net-45 or net-60 with your five largest vendors annually — most will agree in exchange for autopay or a longer commitment.
Use business credit cards for expenses when the interchange cost is less than the 20 to 30 days of float you gain. Card-with-autopay is often the cleanest AP flow.
Never stretch vendor terms silently. Damaged supplier relationships cost more than the working capital gain.

Managing Inventory

Segment SKUs by contribution to revenue and margin. The top 20% by revenue usually accounts for 70–80% of the working capital — that is where the discipline pays off.
Set reorder points and safety-stock levels per SKU. Owner-led businesses over-order because 'we might need it,' which turns cash into shelves.
Track dead inventory monthly. Anything that has not sold in 12 months either gets discounted aggressively or written off — carrying it costs cash and space.
For seasonal businesses, pre-commit to a stock-out policy for the tail of the season. Ending with clean shelves is worth a bit of lost margin.
Negotiate consignment terms with vendors for slow-moving SKUs — the inventory stays theirs until you sell it.

Building the Habit

Report DSO, DPO, and Days Inventory monthly alongside the P&L. What is not measured drifts.
Set annual targets: shrink DSO by 5 days, extend DPO by 3, reduce Days Inventory by 10. Small numbers compound.
Assign owners: someone at the firm owns each metric and reports variance monthly.
Track cash freed up in dollars, not just days. A visible dashboard of 'released working capital' is what keeps the effort going.
