Stored materials billing is the line item every builder eventually wants on a draw and that every lender approaches with caution. The principle is simple: a builder has paid for materials that have not yet been installed, and the builder wants the draw to reimburse the cost so cash flow does not stall. The execution is documentation-heavy because the lender is being asked to fund work that is not in place yet, and the lender wants assurance the materials exist, are insured, and will not walk off the lot before the builder installs them.
Done correctly, stored materials billing keeps a build on schedule when long lead-time items arrive months before installation. Done sloppily, it is the single fastest way to get a draw bounced or, worse, to get the lender to tighten oversight on every subsequent draw.
The four-part principle
Every stored materials line item has to clear four hurdles, every time, no exceptions. First, the materials must be paid for, with a paid invoice from the vendor. A purchase order is not enough. A deposit on the materials is not enough. The full invoice paid in full, with bank evidence of the payment, is the standard. Second, the materials must be physically secured, either on the project site under lock or at a bonded warehouse off site. A trailer in the yard with no door is not secured. Third, the materials must be insured, with the lender named or with a builder’s risk policy that covers off-site storage. Fourth, the materials must be photographed, with the project ID or the address visible in the frame so the lender can confirm the photo is of these materials at this site.
Skipping any one of the four kills the line item. A lender reviewing a stored-materials request without a paid invoice attached will assume the builder is float-financing through the draw, which is what the lender is trying to prevent.
On-site vs. off-site stored materials
On-site stored materials are the easier case. The cabinets sit in the garage, the windows on pallets in the foundation, the lumber under tarp on the slab. The lender is funding materials that are physically present at the project the lender already has a security interest in, with the builder’s site insurance covering the loss exposure. The documentation packet is the paid invoice, a photo of the materials with project ID visible, and a vendor lien waiver covering the materials.
Off-site stored materials are where the documentation gets heavier. The cabinets are at the cabinet shop, the trusses are at the manufacturer, the custom millwork is at the millwork shop. The lender does not have a security interest in the cabinet shop’s premises. The materials could be commingled with another customer’s materials. The shop could go out of business and the materials could be subject to the shop’s creditors. To fund off-site stored materials, lenders typically require a bonded warehouse, an insurance certificate listing the lender as additional insured, and a bailment letter from the warehouse acknowledging the materials are held for the project.
Bonded warehouse rules for off-site
A bonded warehouse is a storage facility that has posted a bond with the state or with a private bonding agent, guaranteeing the goods stored on the premises against loss, theft, or commingling. The bond is what gives the lender comfort to fund off-site materials. The builder asks the warehouse for a bailment letter, which states that the materials at issue (described by invoice and quantity) are held in the warehouse on behalf of the project at the project address, segregated from other customer goods, and insured against loss.
Some lenders will accept off-site storage at a vendor’s premises without a bonded warehouse if the vendor is large enough and the insurance certificate is robust. A national truss manufacturer holding $80,000 in custom trusses for a builder is a different risk profile than a one-person millwork shop holding $30,000 in custom cabinets. The lender’s appetite depends on the vendor.
Lender caps on stored materials
Most lenders cap the percentage of any line item that can be billed as stored materials. A common ceiling is 50% to 75% of the line item value, though some lenders allow up to 100% on certain pre-fabricated items (trusses, engineered LVLs, custom windows) where the bulk of the cost is the material itself rather than the installation. Other lenders cap stored materials at a percentage of the total contract, typically 10% to 20%, to prevent a draw that is mostly stored materials and very little installed work.
| Lender type | Typical cap | Common conditions |
|---|---|---|
| Regional bank | 50–75% of line item | On-site preferred, off-site requires bond |
| Community bank | 10–20% of contract total | Conservative, often case-by-case |
| Hard-money lender | 0–25% | Many decline stored materials entirely |
| Private lender | Negotiated | Per loan agreement |
Hard-money lenders are the most likely to decline stored materials. The hard-money model is built on funding installed work against a fast inspection cycle, and stored materials introduces the risk the model exists to avoid. Builders who plan to use hard money for a build that involves heavy long-lead pre-purchases need to account for the float themselves rather than relying on the draw to reimburse pre-purchase.
The documentation packet
A complete stored materials request includes four documents per line item. The paid invoice, with the bank wire confirmation or cleared check stub. The photograph of the materials with project ID or address visible in the frame, EXIF intact. The certificate of insurance covering the materials, naming the lender as additional insured, with the policy limit at least equal to the materials value. The vendor lien waiver, conditional or unconditional depending on the lender’s preference, covering the specific materials at issue.
The packet is line-item specific. A builder billing $25,000 in stored cabinets and $18,000 in stored windows on the same draw assembles two separate packets, one per line item. The lender reviews each independently because the failure of one does not invalidate the other.
Special cases
Custom millwork is the most common stored-materials line on a high-end residential build. The mill begins fabrication 90 to 120 days before the cabinet install date. The mill takes 50% deposit at order, 40% on completion of fabrication, and 10% at install. The builder wants to bill the lender for the 90% paid before install. The lender wants to see paid invoices, a photograph of the cabinets at the mill with the project ID visible, and a bailment letter or COI naming the lender. Done well, the cabinets are funded through draws 4 and 5, with the install bill landing on draw 6 against the final 10%.
Engineered LVLs and custom-cut beams ship with manufacturer-specific lot numbers tied to the project’s engineering. The builder pre-pays the mill, the materials are stored at the mill or at the lumberyard, and the stored materials request includes the engineering paperwork showing the beams are project-specific. Lenders are generally comfortable funding engineered LVLs as stored materials because the beams cannot be repurposed to a different project without re-engineering.
Factory truss pre-payments are similar. The truss manufacturer cuts the order based on project drawings, the builder pre-pays 30% to 50%, and the trusses sit at the manufacturer until the framing crew is ready. The documentation packet includes the manufacturer’s order acknowledgment showing the project address, the paid invoice, and a photograph of the completed trusses tagged for the project.
The 926 Stratford stored materials run
On the 926 Stratford build (1,784 SF, $430,250 contract), the long-lead items are the custom kitchen cabinets ($28,000), the engineered LVL package ($7,500), and the factory trusses ($14,200). The cabinets are ordered at contract signing for delivery 14 weeks later. The LVLs are ordered at framing start. The trusses are ordered at slab pour for framing-week delivery.
The stored materials line on draw 3 reads $14,400 (50% of cabinet pre-pay) with paid invoice, photo of cabinets in fabrication at the mill with the Sweetwater address tag visible, COI naming the lender, and a conditional lien waiver from the millwork vendor covering the deposit. The stored materials line on draw 2 reads $7,500 (engineered LVLs at the lumberyard, cut for the project, photo with project ID visible, paid invoice, COI). The truss pre-pay clears the same week as the slab pour and shows on draw 1 at $4,260 (30% of $14,200), which the lender funds because the truss manufacturer’s order acknowledgment ties the units to the project.
What to do if the lender rejects
Lenders reject stored materials lines for predictable reasons. The most common is incomplete documentation, which the builder fixes by resubmitting with the missing piece. The next most common is the percentage cap being exceeded, which the builder addresses by lowering the requested amount to the cap. The third is the lender not accepting off-site storage at all, which is a structural decision the builder cannot fix on this draw.
When the rejection is structural, the builder has three options. Pay for the materials out of working capital and bill them on the draw they are installed. Negotiate with the vendor for delayed payment terms (30, 60, or 90 days) so the builder’s payment hits closer to the install date. Switch to a vendor whose terms align with the lender’s draw cycle. The first option costs working capital. The second costs vendor good will. The third costs sourcing time. Builders who run repeat projects with the same lender learn which vendors fit which lenders and pre-empt the rejection before it happens.
How BuilderGrid handles stored materials
BuilderGrid tracks stored materials as a separate sub-ledger against each line item, with the four-part documentation (paid invoice, photo, COI, lien waiver) attached at the line. The system flags whether the storage is on-site or off-site and prompts for the bailment letter or bonded-warehouse evidence when off-site storage is selected. Lender caps are configured at the project level so the builder sees a real-time read on remaining capacity within the cap. Photos preserve EXIF and timestamp, the vendor lien waivers chain through to final waiver release, and the stored materials line on the G702 generates from the underlying ledger rather than being typed by hand.
