Interviewer: What payment term opportunities do businesses overlook?
Aisha Mwangi, Procurement Director: Everyone negotiates the percentage discount or number of days. Almost nobody negotiates invoice timing, payment triggers, or billing milestones. These elements can matter more than the stated terms.
We worked with a construction company paying suppliers on net-30 terms from invoice date. Suppliers invoiced immediately upon delivery, so the company had materials sitting in inventory for 15-20 days before use, but the payment clock was already running. We renegotiated with key suppliers to invoice upon usage confirmation rather than delivery. Same net-30 terms on paper, but effective payment timing shifted out by 18 days on average. That's an extra $340,000 in working capital without requesting extended terms or discounts.
Milestone-Based Payments
Interviewer: How does this work with project-based businesses?
Aisha Mwangi: The standard approach is progress billing—pay as work completes. But you can structure milestones to match your own payment receipt. A marketing agency was paying contractors monthly while billing clients quarterly. They had a consistent two-month cash gap funding contractor costs before client payment arrived.
They restructured contracts to align milestones with their billing cycle. Contractors received 40% at project start, 40% at mid-point review, and 20% at completion—which coincided with when the agency received client payments. Contractors accepted it because total payment and timing were similar; the agency eliminated the funding gap that was costing them $28,000 annually in credit line interest.
Volume-Triggered Terms
Interviewer: What other structures work?
Aisha Mwangi: Volume-based payment terms that adjust based on purchase levels. A restaurant chain negotiated tiered terms with produce suppliers: net-15 for weekly orders under $5,000, net-30 for $5,000-$10,000, net-45 over $10,000. Their average order was $8,200, so they operated mostly in the net-30 tier.
But during peak season, when orders exceeded $10,000 weekly, they automatically shifted to net-45. During their highest-volume eight weeks annually, this provided an extra $164,000 in cash flow exactly when they needed it most for seasonal staffing and inventory.
Seasonal Structures
Interviewer: How do seasonal businesses handle this differently?
Aisha Mwangi: Seasonal payment terms that acknowledge business cycle realities. A sporting goods retailer negotiated net-60 terms for inventory received September through November, when they're building stock for holiday season, but net-30 for December through August. Suppliers agreed because they understood the business model and preferred the partnership to rigid terms.
The retailer gained breathing room exactly when cash was tightest—during pre-season inventory buildup. Annual working capital impact was roughly $520,000 compared to standard net-30 terms year-round.
These structures require explanation and relationship capital with suppliers. But the cash flow benefits come without requesting discounts or damaging supplier economics.
