Billing stored materials: how to get paid for gear that is on site and not installed

Your supplier releases the switchgear the day the submittal comes back approved. It ships eleven weeks later, in March. The electrical rooms are not ready until July.

You owe the supplier in 30 days. The GC often pays you 30 days after they get paid by the owner, on work you have not installed yet. That is four months of six-figure equipment sitting on your line of credit, in a building you do not own, for a job that has not reached 10% complete.

Stored-material billing is how a sub stops funding that. It is also one of the most reliably rejected lines on a draw, almost always for reasons that were decided months before anyone tried to bill it.

Which trades this is really about

Any sub can have a stored-material month. For some, it is the whole cash-flow shape of the job:

• Electrical. Switchgear, panelboards, transformers, generators — released at submittal approval, delivered months ahead of the rooms that take them.
• Mechanical/HVAC. Air handlers, chillers, rooftop units. Big, early, and frequently craned in before the roof closes.
• Glazing and curtain wall. Custom fabricated aluminum and glass, which cannot be ordered until the openings physically exist and cannot be returned once it is cut.
• Fire sprinkler. Pipe, fittings and heads bought at a price before an increase.
• Low voltage and data. Cat6A reels, racks, patch panels and fiber, ordered at award for lead time and then locked in an IDF until the ceilings are ready.

The pattern is the same everywhere: a long-lead item whose purchase date and install date are separated by months, and a supplier whose terms do not care about either.

The decision that actually determines whether you get paid

Here is the uncomfortable part. Whether you can bill stored material is settled in two places, and neither of them is the draw:

1. Your subcontract. The stored-material clause either exists or it does not. It typically sets conditions — material on site, insured, title passing to the owner on payment, segregated and marked for this job, and support documentation with the billing. Some contracts allow off-site storage; many do not without a separate agreement. Your contract and your state’s law decide, not this article.

2. Your schedule of values, before it locks. If material and the labor that installs it are one blended line, there is nowhere to put $240,000 of switchgear. You can only bill a percentage of a line that includes installation you have not performed — which is either understating what you are owed or overstating progress, and a GC’s project engineer will catch the second one.

So the move is to split the lines when you build the SOV:

Instead of	Split into
Switchgear & distribution — $610,000	Switchgear material — $380,000 · Stored material allowance (handling/storage) — $15,000 · Switchgear installation — $215,000

Now March’s draw has a line to bill, and July’s draw has a separate one.

This matters more than it sounds, because on most jobs the schedule of values is effectively fixed once the first pay application goes in. After that, you are usually not re-splitting lines — you are negotiating a revision with a GC who has already billed the owner off your numbers. Get the split in at buyout. Schedule of values for subcontractors is the longer version of how to build one that survives.

If the job is unit-priced, the problem is harder and the lesson is the same. A line that pays on installed quantity has no room for forty tons of duct in a trailer. You need an explicit stored-material treatment agreed up front or you float your supplier out of your own cash — the trade-off covered in percent complete vs. unit price billing.

The support package

A stored-material line with no file behind it is a line that gets removed. Assume you are proving four things, and assemble it as the material arrives rather than at cutoff:

• That you bought it for this job. The purchase order, referencing the job. If POs are issued against the job from the start, this is free; if they are not, this is where the argument starts. The purchase order process for subcontractors covers the habit.
• That it arrived. The signed delivery ticket, dated. Plus the supplier’s invoice, which is also what the GC uses to check you are not marking material up beyond your contract terms.
• That it is where it is supposed to be. A dated photo of the material in its storage location, ideally with something in frame that places it on site. If it is segregated and marked for the job, photograph the marking. This is the single easiest item to produce if a foreman is already writing a daily log, and the single hardest to reconstruct in October for a delivery in March.
• That it is insured, and whose it is. Many contracts require evidence of insurance covering the material while stored, and a bill of sale or title-transfer letter passing title on payment. Off-site storage often adds a bonded warehouse, a separate certificate, and the GC’s right to inspect. What is actually required comes from your contract, the owner’s lender and your state, so confirm it before the first stored-material draw.

Nothing here is exotic. All of it is trivially easy on the day and genuinely painful four months later, which is the entire argument for logging it when it lands.

The drawdown, which is where subs get caught

This is the part almost nobody is told, and the part that causes the awkward phone call.

Stored material is not revenue you keep claiming. It is a holding position. As the material gets installed, it has to move out of the stored-material column and into work completed, in the same amount. If it stays in both, you have billed the same switchgear twice, and that is what it will look like to the GC’s accountant — not like a bookkeeping slip.

Concretely, over three draws on that $380,000 of switchgear:

Draw	Stored materials	Completed to date
March	$380,000	$0
July	$160,000	$220,000
August	$0	$380,000

Stored goes down exactly as completed goes up. The total billed on the material never exceeds $380,000. Keep the two in separate fields on the line and this is arithmetic; blend them into one percent-complete figure and it becomes a reconciliation nobody wants to do.

Two more things that catch people:

• Retainage often still applies to stored material, depending on your contract and state law. Billing $380,000 at 10% retainage brings in $342,000, not $380,000 — which may still not cover the supplier invoice. Check the rate before you promise accounting a number.
• Material you have already installed is not stored material. If the crew set the panels the week before the cutoff, that value belongs in completed work. Billing it as stored because the stored line is easier to support is the version of this that ends a relationship with a GC.

A realistic calendar

Running it as a monthly rhythm rather than a monthly scramble:

1. At buyout — read the stored-material clause, and split material, stored material and install labor into their own SOV lines before the first draw locks it.
2. At release — issue the PO against the job, so committed cost shows up before cash does.
3. On delivery — delivery ticket, dated photo, storage location noted in the daily log. Same day.
4. Three to four days before the GC’s cutoff — build the draw: percent complete per line, stored materials in their own field, approved change orders added, retainage applied. The billing cycle deadlines article is about running that cutoff across several GCs at once.
5. Each month after install starts — draw the stored line down by exactly what moved into completed.

Where SubMark fits

SubMark does not generate your GC’s billing forms, and it does not submit for you — you submit through whatever system that GC uses. What it holds is the thing that makes the above repeatable:

• One schedule of values per job, built line by line against a real contract value, with a materials-stored field on each line of each pay application you build in SubMark, separate from work completed this period. Stored material from an earlier draw rolls into that line’s previous-to-date figure rather than carrying as its own balance, so the drawdown table above is still a reconciliation you keep yourself. A draw you log from a GC’s pay-app PDF records the G702 summary only, where completed and stored are one figure.
• It locks when the first pay application you build in SubMark is submitted, which is the deadline this article keeps pointing at.
• Purchase orders against the job, so the switchgear is committed cost in job costing from release rather than a surprise when the invoice arrives, and pushed to QuickBooks Online with a click when you want it there.
• Daily logs from the field, which is where the dated delivery record and photo live without anyone building a separate folder for them.
• Approved change orders are added to the SOV automatically, so a change order that brings its own long-lead material gets a line instead of a note.

The gear is going to land four months early whether or not your paperwork is ready. The difference is whether that is four months of your credit line or one month of your GC’s.
