ELECTRICAL SUBCONTRACTOR CASH GAP BEFORE FIRST PAYMENT.

QUICK ANSWER

The average commercial electrical subcontractor deploys costs for 73 days before the first check clears. Switchgear deposit on day one. Mobilization week two. Rough-in labor and conduit material weeks two through six. First pay app submitted at the end of month one, then GC billing to the owner, owner payment, GC processing, and a check in the bank at day 73. Every one of those days is funded by the LOC, by cash reserves, or by both. Understanding the 73 day cycle is a business planning exercise rather than a problem-solving one, because every commercial electrical project has it. The questions are whether the LOC is sized to cover it, whether the mobilization SOV line recovers some of it early, and whether stored materials billing is in the contract to recover the switchgear deposit before installation.

Nothing on that timeline is a mistake. The gear doesn't reach the site until week 14, the GC has a billing cut-off that ignores your progress, and the owner pays on his own cycle. That's the trade in commercial electrical work. What separates the contractor who runs it comfortably from the one who maxes the line in month two is three contract terms and one forecast, all of which get decided before mobilization. After mobilization the only tool left is borrowing, and borrowing at week six costs more than negotiating at signing.

THE DEFINITION

WHAT IT MEANS.

The 73 day cycle before first payment is the stretch where a commercial electrical subcontractor funds switchgear deposits, mobilization, and rough-in labor out of its own cash or line of credit before the first check clears.

WHAT WE SEE IN THIS BUSINESS

WHAT HAPPENS BETWEEN CONTRACT SIGNING AND FIRST PAYMENT.

01

The switchgear deposit goes out on day one and can't be billed until week 18

The deposit is paid the day the contract is signed and the order goes in, which is $42,000 out of cash immediately. The gear doesn't reach the site until week 14, when the balance due on delivery is another $58,000, and none of it can be billed until it's installed in week 18. That's four months of carrying somebody else's equipment on your line of credit.

02

The GC's billing cut-off decides when you can bill, not your progress

The first pay app goes in at week 4, but the GC's billing cut-off was week 3, so the next one is week 7 and everything built in between waits. Overhead runs at $8,000 a week the whole time, and the underground conduit order took another $18,000 in material deposits at week 3. By week 8, with a second pay app submitted, cash deployed is $124,000 or more and no checks have been received.

03

One project can max the whole line

By week 14, most electrical contractors have deployed $180,000 or more on a $480K contract and collected $48,000. The $132,000 difference is funded by the LOC. On a contractor with a $250,000 LOC and two other active projects, this one job can max the line before the switchgear is even installed.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The 73 day timeline

Day 1, contract signed and switchgear ordered, deposit paid, $42,000 out of cash immediately. Week 2, mobilize with temporary power, site setup, and the first conduit runs, and overhead begins at $8,000 a week. Week 3, the underground conduit order for conduit, fittings, and pull boxes, $18,000 in material deposits. Week 4, first pay app submitted, though the GC billing cut-off was week 3 and the next cut-off is week 7.

Where it peaks

Week 8, second pay app submitted, cash deployed so far $124,000 or more, still no checks received. Week 10, the first check comes in for pay app 1 at $48,000, with the LOC still drawn for the balance. Week 14, the switchgear reaches the site with $58,000 due on delivery, and it can't be billed until installation in week 18.

HOW SPM FIXES IT

THREE TOOLS, IN ORDER OF IMPACT.

Stored materials billing for switchgear

Negotiate a stored materials line into the SOV at contract signing. When the switchgear deposit is paid and the purchase order goes in with documentation, bill the stored materials line at the deposit amount. The GC approves it with a materials submittal, proof of purchase, and a lien waiver, so the deposit is recovered before installation. This is the single highest-impact change to electrical cash flow, because it turns a 6-month carrying cost into a 30-day billing event.

Mobilization SOV line at 8 to 10% of contract

A mobilization line weighted at 8 to 10% of contract value covers temporary power, site setup, and initial procurement deposits. On a $480K contract, 9% mobilization is $43,200, billed when equipment is on site and temporary power is established. That covers the initial mobilization costs and reduces the LOC requirement in the first 30 days, before any production billing gets moving.

LOC sized to peak electrical draw before contract signing

Calculate the peak LOC requirement before signing: switchgear deposit plus conduit order deposit plus the weeks of overhead and labor until first payment. That total is your minimum available LOC requirement. If current availability is below that number, either get an increase before mobilization or negotiate stored materials billing before signing, because finding the shortfall at week six means borrowing at the worst possible time.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

COMMON QUESTIONS

FREQUENTLY ASKED.

On a $500K commercial electrical contract with a 60-day payment cycle: switchgear deposit $40,000 to $60,000, conduit and wire deposits $15,000 to $25,000, and 10 weeks of labor and overhead at $18,000 a week, which is $180,000. Total peak LOC requirement is $235,000 to $265,000 before any revenue is received. If stored materials billing covers the switchgear, the requirement drops to $155,000 to $195,000. Size the LOC to the higher number and use stored materials billing to reduce the actual draws.
The standard package is a materials submittal identifying the equipment with manufacturer and model, a purchase order or supplier invoice showing the deposit amount, a warehouse receipt or on-site storage confirmation, a conditional lien waiver for the stored material value, and a certificate of insurance listing the GC and owner as additional insureds. Some GCs also require a joint check agreement. Put that package together at contract signing rather than when the gear is ordered.
Yes. The 13-week cash flow forecast for electrical contractors maps switchgear deposit dates, conduit order dates, pay app submission dates, and expected collection dates explicitly, rather than as one material cost line. Each major cash outflow and inflow event is its own line on the weekly forecast, so the peak LOC draw week is visible before mobilization. Stored materials billing recovery is mapped to its expected approval date. The whole stretch is managed in advance instead of discovered at week eight.
