Work backward from the selling period
Build the inventory plan around expected selling dates, supplier lead times, shipping, receiving, and preparation. Include delays that would move stock past the relevant season. A revenue forecast alone will not show whether goods arrive in time to earn that revenue.
Record supplier deposits and final-payment dates separately from the inventory receipt date. The company may need cash months before a customer order is placed.
Model the full purchase commitment
Include product costs, freight, duties, warehousing, and other cash required to get stock ready. Identify minimum orders, cancellation terms, and nonrefundable amounts. Ask the accountant which costs enter inventory under the applicable policy.
For illustration, a $60,000 purchase with a thirty-percent deposit needs $18,000 immediately and $42,000 according to the remaining terms, before freight or duties. Showing $60,000 only in the arrival month hides the earlier cash commitment.
Make sales and collection assumptions separate
Estimate unit sales by product and period, using actual demand evidence where available. Then apply payment settlement timing, returns, taxes, and fees. A sold unit does not necessarily create the same week's usable bank cash.
Review downside cases for delayed arrivals, slower sell-through, and heavier returns. State which assumptions are uncertain and what evidence would justify increasing the buy.
Preserve cash for operating obligations
Place the purchasing schedule beside payroll, rent, taxes, debt, and essential vendors. Check the lowest projected cash point before approving the order. Revenue from the peak season may arrive after the company must fund ordinary obligations.
Consider staged orders or negotiated terms only where operationally and contractually feasible. Show the effect on availability and unit economics rather than assuming smaller purchases are always better.
Review sell-through while you can still act
Compare actual unit sales and cash receipts with the plan during the season. Identify products holding cash and purchasing commitments that can still be changed.
After the season, reconcile remaining stock, returns, and write-offs. Keep the outcome with the original assumptions. The next buying cycle should use the evidence of what sold, what arrived late, and how much cash remained tied up.
