Map the season from the first commitment
Seasonal cash planning starts when the company orders stock, books capacity, or commits to marketing, not when the sales event begins. Put supplier deposits, final payments, temporary staffing, fulfillment, and advertising bills on dates. Identify which commitments can still be changed.
Use last season's actual bank movements and operating records where they remain relevant. Adjust for changed prices, product mix, payment terms, and scale. A larger sales target does not mean every cost and receipt will increase smoothly by the same percentage.
Forecast when sales become available cash
Separate order placement, shipment, customer collection, processor settlement, and bank availability. Include the actual channels used by the business. Marketplace reserves, wholesale credit terms, and customer returns can make two equally sized sales channels produce different cash patterns.
In an illustrative season, the company pays $60,000 for stock in October and expects $100,000 of customer receipts in November and December. If another $20,000 of operating costs falls before those receipts, the business needs funding for that earlier outflow even if the season's final contribution is positive.
Test unsold stock and late receipts separately
A demand shortfall leaves cash tied up in inventory. A payout delay leaves completed-sale proceeds unavailable. Model both rather than placing one general contingency percentage on the final profit. Include the timing of returns and any costs of holding stock after the peak.
Compare weekly balances during the tightest period if a monthly total hides the low point. A month can end with positive cash even though payroll falls before a large customer receipt. Use the actual dates for the payments that could create that temporary shortfall.
Approve limits before the commitments become fixed
Agree purchase quantities, advertising limits, contingency actions, and a minimum operating buffer. Evaluate financing only from confirmed terms and availability, with professional review where needed. An expected credit-line increase should remain a scenario until the facility is actually available.
During the season, replace estimates with actual orders, payouts, and supplier confirmations. Afterward, reconcile the forecast with the completed season, including returns and leftover stock. Preserve the timing differences so next year's plan starts with evidence rather than only the peak sales headline.
