ELECTRICAL CLUSTER · PAIN POINT

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 end of month one. GC billing to owner. Owner payment. GC processing. Check in the bank at day 73. Every one of those days is funded by the LOC, cash reserves, or both.

Understanding the 73-day cash gap is not a problem-solving exercise — it is a business planning exercise. Every commercial electrical project has this gap. The question is 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.

THE 73-DAY TIMELINE

WHAT HAPPENS BETWEEN CONTRACT SIGNING AND FIRST PAYMENT.

DAY 1

Contract signed. Switchgear ordered. Deposit paid: −$42,000 out of cash immediately.

WEEK 2

Mobilize. Temporary power, site setup, first conduit runs. Overhead begins: −$8,000/week.

WEEK 3

Underground conduit order: conduit, fittings, pull boxes. −$18,000 material deposit.

WEEK 4

First pay app submitted. GC billing cut-off was week 3. Next cut-off is week 7. Waiting.

WEEK 8

Second pay app submitted. Cash deployed so far: −$124,000+. Still no checks received.

WEEK 10

First check arrives — pay app #1 collected. +$48,000. LOC still drawn for the balance.

WEEK 14

Switchgear arrives. Balance due on delivery: −$58,000. Cannot bill until installed in week 18.

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

HOW TO FUND IT

THREE TOOLS THAT REDUCE THE 73-DAY GAP — IN ORDER OF IMPACT.

TOOL 01 — HIGHEST IMPACT

Stored Materials Billing for Switchgear

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

TOOL 02

Mobilization SOV Line at 8–10% of Contract

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

TOOL 03

LOC Sized to Peak Electrical Draw Before Contract Signing

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

COMMON QUESTIONS

FREQUENTLY ASKED.

What is the typical LOC requirement for a $500K electrical subcontract?

On a $500K commercial electrical contract with a 60-day payment cycle: switchgear deposit $40,000–60,000, conduit and wire deposits $15,000–25,000, 10 weeks of labor and overhead at $18,000/week = $180,000. Total peak LOC requirement: $235,000–$265,000 before any revenue is received. If stored materials billing covers the switchgear, the LOC requirement drops to $155,000–$195,000. Size the LOC to the higher number and use stored materials billing to reduce actual draws.

What documentation does the GC need to approve stored materials billing?

Standard package: materials submittal identifying the equipment with manufacturer and model, purchase order or supplier invoice showing the deposit amount, warehouse receipt or on-site storage confirmation, conditional lien waiver for the stored material value, and certificate of insurance naming the GC and owner as additional insureds. Some GCs require a joint check agreement. Prepare this documentation at contract signing, not when the gear is ordered.

Does CFOS model the 73-day cash gap for electrical clients?

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 — not as a single material cost line. Each major cash outflow and inflow event is a separate line on the weekly forecast. The peak LOC draw week is visible before mobilization. Stored materials billing recovery is mapped to its expected approval date. The gap is managed in advance, not discovered at week eight.
