PROCUREMENT AND CASH FLOW

PROCUREMENT TIMING IS
A CASH DECISION.

THE SHORT ANSWER

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.

HOW THE CRISIS BUILDS

FOUR WAYS PROCUREMENT TIMING
TRIGGERS CASH CRISES.

01
ORDERING EARLY TO GUARANTEE AVAILABILITY
The PM orders pipe 12 weeks before installation "to make sure it's there." The supplier delivers in week 8. The pipe sits in the yard for 4 weeks before the trench opens. Four unnecessary weeks of carrying $180K in pipe cost. Multiply across five jobs each with similar early ordering patterns and the company has $900K of avoidable float at any given time.
02
OVERLAPPING PROCUREMENT ON MULTIPLE JOBS
Three jobs mobilize in the same month. Each PM places major material orders simultaneously. The aggregate procurement payment is $520K hitting in a 3-week window. The LOC is $400K. The company draws the full LOC, calls suppliers for short extensions, and spends the next 6 weeks managing the gap instead of managing the work. The jobs weren't sequenced to stagger the procurement cash demand.
03
NO STORED MATERIALS BILLING IN THE SOV
Material arrives. No stored materials line in the SOV. The material sits until installation. Billing triggers at installation. Collection runs 45 days after. Total gap from delivery to cash: 8–12 weeks. With a stored materials line, the billing event triggers at delivery. Gap: 5–10 days. Same material, same job, same GC — different SOV structure produces a fundamentally different cash profile.
04
PROCUREMENT NOT IN THE CASH FORECAST
The 13-week cash forecast is built from billing collections, payroll, and overhead. Nobody mapped the $280K pipe order landing in week 6. When it hits, it's a surprise. The LOC draw happens reactively instead of proactively. A proactive draw 4 weeks before the payment is a planned financial action. A reactive draw the week of the payment is a cash crisis that looks like a bank account problem but is actually a forecasting problem.
THE FIX

PROCUREMENT CASH MANAGEMENT
IN THREE STEPS.

1

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.

2

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.

3

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.

FAQ

COMMON QUESTIONS.

Procurement timing causes cash crises because material payment happens before billing collection. A purchase order placed 8 weeks before installation, paid on delivery, and billed after installation creates a 60–90 day gap between cash out and cash in. When multiple jobs are ordering simultaneously, the overlapping procurement gaps stack — creating a cash demand that exceeds the LOC capacity.

Material should be ordered as late as possible while still meeting the installation schedule — not as early as possible to guarantee availability. Every week earlier than necessary is another week of carrying the cost before billing. The procurement schedule should be built backward from the installation date, not forward from the contract execution date.

Map every active job's pending material orders with their payment dates and expected billing dates. The difference between payment dates and billing collection dates is the float requirement for each order. Aggregate across all active jobs to get total procurement float at any point in time. Run this as a 13-week rolling forecast so LOC draws can be planned 4–6 weeks before the gap hits.

Stored materials billing compresses the procurement-to-billing gap from weeks to days by allowing billing at delivery rather than at installation. Combined with procurement timing discipline — ordering as late as safely possible — stored materials billing means the cash gap between procurement payment and billing collection is measured in days, not months.
