Material deposits and supplier COD (cash on delivery) are one of the most common “quiet killers” of contractor cash flow. You can be profitable and still get trapped because procurement cash goes out immediately while progress payments arrive later—especially when long-lead items, custom orders, or new supplier accounts require deposits. This guide explains the material deposit / supplier COD cash gap and the practical fixes contractors use to stay liquid without turning one project into a company-wide cash crisis.
Why material deposits hit before your first draw
Even when your contract is solid, the timing often looks like this:
- Week 0–1: you mobilize and place long-lead orders
- Week 1–2: suppliers require deposit/COD to release materials
- Week 3–6: first pay application gets approved and paid
If you’re also dealing with up-front mobilization costs, see mobilization funding before the first draw.
The root cause: procurement cash-out + payment lag
Suppliers aren’t doing this to be difficult. They’re managing risk: price volatility, lead times, custom manufacturing, and contractor credit exposure. The problem is that the risk gets pushed upstream to you—right when your cash buffer is already under pressure.
7 reasons suppliers demand deposits/COD (and what to do)
1) New supplier account / limited payment history
If your account is new, suppliers often require deposits until trust is established.
Fix: Start terms conversations early and ask for a path to net terms after a defined number of paid invoices.
2) Long-lead or custom materials
Custom items and long-lead materials tie up supplier capital for weeks. Deposits are common.
Fix: Align procurement milestones to billing—use stored materials billing where permitted.
3) Volatile pricing and escalation risk
When prices are moving, suppliers want money committed to protect themselves.
Fix: Lock pricing in writing and negotiate partial deposits tied to confirmed production milestones.
4) Your job is large relative to your normal volume
Even good contractors get COD when an order size is outside the supplier’s comfort zone.
Fix: Break orders into phased releases and ask for terms on subsequent releases after first delivery.
5) Your cash flow looks tight (supplier risk signal)
Suppliers can sense risk through bounced payments, slow pay, or lack of credit references.
Fix: Improve payment consistency and protect your bank statements. See bank statement red flags.
6) The contract structure doesn’t support early procurement billing
If you can’t bill stored materials (or it’s hard to get approved), you’re forced to float the deposit.
Fix: Negotiate stored materials terms and documentation requirements at contract kickoff.
7) You bought equipment with cash and drained your buffer
Cash equipment purchases shrink the buffer that should float procurement.
Fix: Use equipment financing so working capital stays available for payroll and materials.
Stored materials billing: how to do it without getting rejected
Stored materials can bring cash in earlier—but only if you document properly. While requirements vary, approvals typically require:
- Proof of purchase: supplier invoice and paid receipt (or proof of payment)
- Clear identification: materials labeled to the project
- Storage location: on-site or approved off-site storage
- Insurance/security: coverage and protection for stored items
- Contract permission: stored materials language in contract/pay app rules
The goal is simple: make it easy for the owner/GC to approve early materials without fearing double payment or missing delivery.
Why material deposits become a company-wide problem (not just one job)
One deposit hurts. Multiple deposits across multiple jobs can break your working capital, especially when payroll is weekly and progress payments are monthly. This is where profitable contractors get trapped: cash is tied up in materials, while the business still needs liquidity to operate.
Common “stacking” patterns:
- Multiple long-lead orders at once: each job demands its own deposit.
- Slow pay apps: approval and pay lags extend how long your cash is tied up.
- Retainage stacking: even when you get paid, 5–10% is withheld. See retainage cash flow gap.
The fix is to treat deposits as a predictable working-capital requirement and plan liquidity before you place the order.
Negotiation tactics: reduce deposits without burning supplier relationships
- Ask for staged deposits: split into order, production, shipment
- Use joint checks: improves supplier confidence and may reduce COD
- Share job information: GC/owner details, contract value, schedule
- Offer partial prepay + terms: a hybrid that reduces cash-out
- Build credit references: provide references that show on-time history
Even small concessions can reduce the spike enough to avoid emergency borrowing.
Common contractor scenarios (and the best-fit fix)
Scenario: The GC wants you to order long-lead items immediately
This is common on projects with tight schedules. The problem is that “order now” often means “deposit now” while your first draw is still weeks away.
- Fast fix: request a stored materials billing path before you place the order.
- Risk fix: get written confirmation that stored materials are billable and what documentation is required.
Scenario: Supplier requires COD because your account is new
New accounts often start as COD. If you accept it forever, you’re financing procurement permanently.
- Fast fix: negotiate a step-down plan (COD → net-7 → net-14 → net-30) tied to paid invoices.
- Process fix: keep payment consistency perfect for the first 90 days of the relationship.
Scenario: You can’t bill stored materials (contract restriction)
If the contract won’t allow stored materials billing, you must fund the deposit another way: negotiate supplier terms or use a bridge.
- Fast fix: stage procurement so deposits are smaller and timed to when you can bill.
- Financing fit: project-sized working capital, not permanent high-cost debt.
What lenders look for when deposits are the pain point
Lenders generally fund the working-capital gap created by timing. When deposits are the need, they’ll look for stable deposits, clean statements, and a clear use of funds.
- Deposit stability: consistent deposits reduce perceived risk.
- Clean statements: fewer NSFs/overdrafts improves options.
- Clear use of funds: “material deposits for long-lead items” is underwriteable.
- Existing obligations: heavy daily debits can limit better options.
If statements are already stressed, review bank statement red flags.
Financing options that fit procurement spikes
Upfront procurement is usually a timing gap. Match the product to the timing.
| Situation | Best-fit product | Why it fits |
|---|---|---|
| One job with a defined deposit spike | Working capital | Sized to the procurement gap while pay apps catch up |
| Recurring deposits across multiple jobs | Line of credit | Revolving liquidity that resets as payments come in |
| Equipment purchase competing with materials | Equipment financing | Preserves working capital for procurement and payroll |
What to avoid (procurement cash traps)
- Ordering long-lead items with no liquidity plan: deposits are predictable; plan them.
- Funding deposits with high-frequency debt: daily/weekly debits can crush cash flow.
- Blending procurement spikes into “normal cash flow”: model it as a separate event.
- Letting CO delays stack on top of deposits: change order delays often add a second timing gap. See change orders delaying payments.
Quick model: how much float do you need?
Use this simple model before you place the order:
- Deposit amount: cash out now
- Approval lag: weeks until you can bill stored materials or progress
- Pay lag: weeks until cash hits the bank
- Buffer: at least 1–2 payroll cycles in cash
If the deposit plus buffer exceeds your safe cash, you need to either negotiate the deposit, accelerate billing, or use a bridge.
Procurement cash flow checklist (use before you place the order)
Run this checklist to avoid “we ordered it and now we’re stuck” moments:
- Do we have stored materials permission? in the contract
- Do we know the documentation requirements? invoice, storage, insurance, labeling
- Is the deposit staged? order/production/shipment
- Is supplier exposure capped? don’t tie up all liquidity with one order
- Is the cash forecast updated? next 6–8 weeks
- Is there a bridge plan? if deposit exceeds safe cash
Most contractors don’t need a new product for every deposit. They need a system that anticipates procurement spikes and keeps liquidity available.
How this connects to progress payments (and why it matters)
Deposits hurt most when your progress payment cycle is slow or unpredictable. If approvals take longer, your cash stays trapped longer. That’s why procurement planning should always be paired with a weekly cash forecast and clear billing cadence.
If you routinely feel squeezed between draws, review cash flow between draws and build a process to shorten the cycle where possible.
One-page operating system (so deposits stop being emergencies)
If your team keeps getting surprised by deposits, use this simple operating system:
- Weekly: update a 6–8 week cash forecast and list upcoming procurement deposits by job.
- Weekly: confirm stored materials documentation requirements for any long-lead items ordered.
- Weekly: confirm supplier term status (COD vs net terms) and progress toward better terms.
- Monthly: review which projects create the biggest procurement spikes and adjust bidding assumptions.
This turns procurement deposits into planned working-capital events instead of “surprise” cash crises.
Final checklist: when you should pause procurement
Sometimes the right move is to pause until one of these is true:
- You have interim approval for stored materials or an early pay app item
- The supplier deposit is staged and aligned to the schedule
- You have a bridge that won’t starve payroll
Pausing procurement is uncomfortable, but financing a job with no plan is worse.
Quick glossary
- COD (cash on delivery): supplier requires payment before releasing materials.
- Deposit: partial prepayment to secure production or release of materials.
- Stored materials: materials purchased and stored before installation that may be billable with proper documentation.
- Float requirement: cash needed to cover outflows while waiting for payments.
When these definitions are shared across your PMs, supers, and accounting team, approvals move faster and the cash cycle improves.
Final Thoughts
Material deposits and COD aren’t a moral failing—they’re a timing problem. Contractors who stay liquid treat procurement spikes as predictable events: negotiate supplier terms, use stored materials billing when allowed, and keep revolving liquidity available for recurring gaps.
