Why a busy production line can still run short of cash
Smith-Midland Corporation’s 2024 annual report says contractor-set schedules generally provide payment 45 to 75 days after its products are produced, while the company bears production costs first. That is one documented example of how a busy production operation can still face a cash gap. In modular construction, the pressure can build between procurement and installation: deposits may arrive early, but later invoices can depend on production milestones, shipment or delivery. Revenue and production volume alone do not show whether cash is available when payroll, suppliers and freight bills fall due. [4] [2]

The payment calendar can lag behind the factory calendar
Offsite construction puts work ahead of what a customer can see on site. A modular project may require a manufacturer to reserve a production slot, order long-lead materials, fabricate modules and arrange transport before installation begins. HUD’s 2022 research roadmap lists Capital, Finance, and Insurance and Project Delivery and Contracts among six priority areas for offsite housing research. The roadmap identifies these as research topics; it does not establish any particular payment practice. [1]
A project manager’s manual prepared for Mercy Housing California by the advisory firm Proyecto, with Guerdon Modular Buildings as modular consultant, sets out a demonstrative payment schedule. It allocates 5% of modular fabrication cost to a production-capacity deposit at the letter of intent, 10% to long-lead materials due 20 weeks before production, and 10% to a contract deposit about four months before fabrication. During fabrication, 30% is due weekly as production begins; another 25% is due weekly for units off the line, 15% for units ready to ship and 5% for units delivered. The schedule is an example, not an industry standard or current market benchmark. [2]
The manual assumes the developer owns work in process during fabrication and says the financier will require adequate insurance. It also says the developer and financial partners should agree on the source, schedule and amount of funding disbursements, including early payments to secure a place in the fabrication queue. In this sample, that means financing must cover early deposits as well as costs as work advances. [2]
Payroll and materials leave between payment triggers
In the manual’s demonstrative schedule, fabrication-stage payments are due weekly for units that have commenced production, exited the production line, are ready to ship or have been delivered. The manual’s fabricator-payment example says specified amounts are paid to escrow. Those are project payment triggers; they do not establish when a manufacturer pays its own workers or suppliers. For a manufacturer, the relevant cash gap is the interval, if any, between its outflows and release of the related payment. [2]
Public company filings show how timing differences appear in accounts. Art’s-Way Manufacturing’s 2025 annual report says payment terms for its Modular Buildings segment vary by contract but typically include money down and progress payments. The filing describes contract assets as costs and estimated gross profit in excess of billings. Those balances record work performed ahead of billing; they do not mean the same amount is already available in cash. [3]
Shipment does not always end the cash gap
A finished module may still be waiting for transport, site readiness, lifting equipment or installation. The manufacturer may keep paying staff and suppliers as the project moves through those stages, while payment depends on a contractual trigger. In the Mercy Housing manual’s sample, payments continue through ready-to-ship and delivery milestones, and a separate schedule lists a modular retention release after the crane set. [2]
Smith-Midland Corporation, a Virginia-based precast concrete manufacturer whose products include transportable concrete buildings, reported in its 2024 annual report that contractor-set production schedules generally provide payment 45 to 75 days after its products are produced. The company said it must bear production costs before receiving payment; under some contracts, retainage may be held until the entire project is complete. These are Smith-Midland’s construction-product contracts, not modular housing terms, but they document how a manufacturer can finish production and still wait for cash. [4]
The timing, not revenue alone, reveals a cash strain
Review each project from cash out to cash in: supplier deposits and due dates; payroll and factory overhead during production; invoice triggers; time to customer approval and payment; freight costs; installation obligations; and any retainage or final acceptance condition. Compare those dates with cash available and committed credit. A project can be profitable on paper yet create a short-term funding need if its bills fall due before collections. A large contract asset or busy production line by itself does not prove financial distress. [3] [4]
For a manufacturer’s own case, request a consented, project-level schedule of invoices, payment due dates and actual collection dates, matched to payroll, supplier, freight and installation outflows. An accountant should reconcile it with the ledger and clarify which amounts are billed, unbilled, disputed or retained. That evidence locates the cash pinch; revenue totals cannot substitute for it.
