7 Cash Flow Scenarios Every Product-Based Business Should Model Your product is selling. Revenue is climbing. And your business is probably running out of cash anyway. This isn't a profitability problem. It's a timing problem. Cash doesn't arrive when you record the sale—it arrives 30, 60, or 90 days later. Meanwhile, you're paying manufacturers, 3PLs, and your team today. Most founders discover this gap when it's already a crisis. The fix is modeling. Not once. Not in a spreadsheet you update quarterly. But seven specific scenarios that every CFO asks about. If you haven't answered them, you're flying blind. 1. Net 90 Payments: When Your Biggest Retailer Extends Payment Terms You land the big account. Target or Whole Foods. Congratulations. Now they're asking for net 90 instead of net 30. That's 60 extra days of borrowed money sitting between you and your cash register. Here's the math: $100k monthly revenue from this account Net 30 = you wait 30 days to get paid Net 90 = you wait 90 days to get paid That's an extra $200k stuck in accounts receivable for 60 days For a bootstrapped company with $300k in the bank, that's a near-death experience masquerading as growth. Most founders say yes to the terms without modeling it first. The fix: Model it before you sign. If the cash gap exceeds your reserves, you'll either need a line of credit, a working capital facility, or renegotiated manufacturer terms. Lenders routinely ask for this scenario—it's table stakes for any working capital discussion. 2. Large Retailer Partnerships: Inventory and Working Capital Requirements Costco wants to stock your product in 500 locations. The purchase order is massive. The inventory requirement hits like a truck: you need to manufacture 2-3 months of inventory upfront, pay the manufacturer within 30-45 days, and then wait for Costco to sell through the units and pay you 60+ days after that. In between, you're out millions in working capital. We've seen this break otherwise healthy companies. Before you celebrate the partnership, model what it does to your cash position. Factor in: Full upfront manufacturing cost Manufacturer payment terms (usually net 30 or net 45) Retail payment terms (net 60 minimum for large accounts) Time to sell through (inventory velocity at retail) If you don't have the working capital, you'll either need a line of credit, investor capital, or you'll need to negotiate better terms with the manufacturer. Model it first. Negotiate from facts. 3. 3PL Holding Costs and Unsold Inventory You launched with a big direct-to-consumer push. Spent on ads. Got the...
