PROCUREMENT TIMING IS
A CASH DECISION.
Every material order placed is a cash commitment. The timing of that commitment determines when cash goes out. Combined with billing cycle and collection lag, procurement timing determines how long you carry the cost before the money comes back. Order 10 weeks early on a $200K material package and you carry $200K for 10 extra weeks. On three jobs simultaneously, that's $600K of avoidable float. Most subcontractors never calculate this. They order when the supplier can guarantee availability, not when the cash forecast says it's optimal.
FOUR WAYS PROCUREMENT TIMING
TRIGGERS CASH CRISES.
PROCUREMENT CASH MANAGEMENT
IN THREE STEPS.
BUILD THE PROCUREMENT SCHEDULE BACKWARD FROM INSTALLATION
For each major material order, start with the installation date. Subtract lead time. That's the latest safe order date. Order on that date, not earlier. The difference between "latest safe" and "earliest comfortable" is carrying cost. On a 6-week lead time item with 10 weeks of unnecessary early ordering, you're carrying $X for 4 extra weeks because someone felt better having it in the yard sooner.
MAP ALL PROCUREMENT PAYMENTS INTO THE 13-WEEK FORECAST
Every pending purchase order goes into the cash forecast with its expected payment date. Not the order date — the payment date. Aggregate across all active jobs. When two or three large payments land in the same week, that's a LOC draw candidate — plan the draw 3–4 weeks in advance. The forecast converts procurement timing from a surprise into a managed event.
STORED MATERIALS BILLING ON EVERY JOB WITH SIGNIFICANT MATERIAL VALUE
Any contract with more than $50K in material value that arrives before installation gets a stored materials line in the SOV — negotiated before contract execution. The billing event triggers at delivery. The cash gap compresses from weeks to days. Combined with procurement timing discipline, this pair of practices eliminates most of the avoidable cash crises that come from material-heavy work.
