Quick answer
A manufacturer's funder has to handle the whole cycle, not just the invoice: materials bought months before shipment, a build window, an acceptance period after delivery, and an OEM that pays on 45 to 90 day terms. The right provider can sequence purchase order financing — up to 100% of supplier cost at 1.5%–6% per 30 days — into a receivables facility advancing 80%–95% at 0.75%–3% per 30 days, under one agreement. Compare funders on that handoff, on how acceptance clauses affect eligibility, and on how they treat concentration with a single OEM.
Key takeaways
- The cash gap starts at the raw material purchase order, not at the invoice; a funder who only finances invoices is covering the last third of your cycle.
- Ask how PO financing converts to receivables financing — one agreement and one handoff, or two providers and an intercreditor problem.
- Acceptance, inspection and first-article clauses can delay eligibility by weeks after you have shipped; find out how the funder treats that period.
- Tooling, NRE and engineering charges are frequently ineligible under a PO facility because they are not cost of goods for the order.
- Concentration with one OEM is normal in manufacturing and abnormal to most funders — raise it first and make them state the limit.
Can the funder finance the whole cycle, not just the invoice?
A manufacturer's working capital problem has a shape that most receivables funders are not built for. You commit to raw materials on a lead time measured in weeks or months. You carry labor and machine time through the build. You ship. Then an OEM takes 45 to 90 days to pay, sometimes with an inspection or acceptance window before the clock even starts. A funder who finances the invoice is financing the last segment of a cycle that began long before it.
The question to open with is therefore about range. Can you finance the supplier purchase order for raw materials, and does that convert into a receivables advance when the goods ship and the invoice is raised? Purchase order financing typically funds up to 100% of supplier cost at 1.5%–6% per 30 days and is designed to pay suppliers directly for a confirmed customer order. Receivables financing then advances 80%–95% at 0.75%–3% per 30 days once the invoice exists. The expensive capital is the earlier capital, so the faster the conversion happens, the lower the total cost.
Where a manufacturer gets hurt is in the seam. If the PO facility sits with one provider and the receivables facility with another, there is a security interest conversation between them, a timing risk at the handoff, and two sets of diligence on the same transaction. A funder who can do both under one agreement removes that entirely. If a funder can only do one, ask them directly how they have handled the other side before, and with whom.
- 1The customer purchase order lands. Ask what makes a PO financeable: a firm order rather than a forecast, a named entity, stated quantities and prices, and terms the funder has read. Blanket orders with releases need their own answer.
- 2Supplier costs are approved and paid. Confirm which costs the funder will pay directly, in what form — deposit, balance on shipment, letter of credit — and whether tooling, freight and duty are inside or outside the funded amount.
- 3Materials arrive and the build runs. Ask what reporting they expect during the build and whether anything is required at the work-in-progress stage, since this is the longest and most expensive part of the exposure.
- 4Shipment and invoice. This is the conversion event. Establish exactly what triggers it — proof of shipment, a customer receipt, a portal acknowledgement — and how many days the handoff from PO facility to receivables facility takes.
- 5The receivables advance repays the PO facility. Ask to see the waterfall in writing: advance amount, PO principal and fees repaid, and the net released to you, calculated on a real order rather than a round number.
- 6Acceptance, payment and reserve release. Confirm whether eligibility survives an acceptance period, how a quality hold on part of a shipment is treated, and when the reserve is released after the OEM pays.
How do raw material lead times change the facility I need?
Lead time is the variable that sizes a manufacturer's facility, and it is the one most often left out of the sales conversation. A twelve-week lead time on a specialty alloy or a long-lead electronic component means the money leaves your account three months before the goods leave your dock, and five months or more before the OEM pays. Facility sizing has to be built on that duration, not on a month of sales.
The worked example below runs one OEM order end to end so the duration cost is visible in dollars rather than in percentages.
A $480,000 OEM order with $288,000 of raw material and supplier cost, an 8-week material lead time plus a 3-week build, PO financing at 2.5% per 30 days for roughly 90 days, converting to a receivables advance of 85% at 1.5% per 30 days with the OEM paying on day 60.
| Customer purchase order value | $480,000 |
|---|---|
| Supplier and raw material cost funded at 100% | $288,000 |
| PO financing cost at 2.5% per 30 days over ~90 days (7.5%) | $21,600 |
| Invoice raised on shipment | $480,000 |
| Receivables advance at 85% | $408,000 |
| Released to you after repaying the PO facility and its fee | $98,400 |
| Receivables fee at 1.5% per 30 days, OEM pays day 60 (3%) | $14,400 |
| Reserve released when the OEM pays | $57,600 |
Total financing cost is $36,000 on a $480,000 order — 7.5% of revenue. Gross margin before financing is $192,000, or 40%; after financing it is $156,000, or 32.5%. The order is still worth taking, but only if you priced it knowing the material was going to sit for three months.
Which capabilities should I score a manufacturing funder on?
Score the funder on how well they understand the gap between shipping and getting paid, because that gap in manufacturing is full of contractual tripwires that do not exist in simpler receivables.
| Capability | Why it matters for a manufacturer | What a good answer looks like |
|---|---|---|
| PO-to-receivables sequencing | The cash gap starts at the material purchase, months before an invoice exists | Both facilities under one agreement, with a defined conversion event at shipment and no re-underwriting in between |
| Supplier payment mechanics | Mills and overseas suppliers want deposits, wires or letters of credit, not net terms | Direct payment to named suppliers, ability to fund a deposit and a balance, and experience with the payment instruments your suppliers require |
| Long lead times understood | Facility size and pricing have to reflect months of exposure, not a 30-day cycle | Sizing built from your actual lead time and build window, with the duration cost shown in dollars |
| Progress payment handling | Many large orders bill at milestones rather than on a single shipment | Milestone billings financed against the contract's payment schedule, with the eligibility trigger for each milestone stated |
| Acceptance and quality clauses | Inspection, first-article approval and acceptance periods delay when an invoice becomes collectible | The funder asks about acceptance terms up front and tells you whether eligibility starts at shipment or at acceptance |
| OEM concentration policy | A manufacturer whose largest customer is 60% of revenue is normal; most funders treat that as a limit breach | A stated concentration limit, a willingness to underwrite a strong OEM above the default, and no surprise mid-term reduction |
| Tooling and NRE treatment | Tooling can be a six-figure cost before a single part ships and is often outside cost of goods | A clear statement of what is and is not fundable, given before you quote the program |
| Inventory and WIP position | Work in progress is a large asset that most receivables facilities ignore | An honest answer about whether WIP supports anything, rather than an implication that it does |
| EDI, portals and ASN requirements | Large OEMs invoice through portals with their own document and labeling rules | Familiarity with customer portals, ability to accept the portal's acknowledgement as proof, and no demand that you invoice outside the required channel |
| Existing lender position | Many manufacturers have equipment loans or a bank line with a blanket filing | The funder raises subordination early and has done intercreditor agreements with equipment lenders before |
How do acceptance and quality terms affect when I can be funded?
This is the clause that catches manufacturers out, and it is worth finding before it finds you. Many OEM purchase orders provide that payment terms begin on acceptance rather than on delivery, and that acceptance follows inspection, incoming quality control, first-article approval or a stated acceptance period. A net-60 term that starts at acceptance thirty days after delivery is a net-90 term wearing a disguise, and a receivable that is not yet collectible is not yet reliably fundable.
Ask any funder how they treat the period between shipment and acceptance. Some will advance at shipment against a clean proof of delivery and carry the acceptance risk inside the reserve. Some will hold the invoice ineligible until acceptance is evidenced. Both are defensible positions; what is not defensible is a funder who has never considered the question, because they will quote you a cost of funds based on a 60-day cycle and then be surprised at 90.
The related issue is partial shipments and short counts. Manufacturing orders are frequently fulfilled in releases against a blanket purchase order, and a release short by 40 pieces produces an invoice the OEM will pay in part or not at all until the balance ships. Ask how partial deliveries are treated, whether each release is separately eligible, and what happens to the advance when a release is returned for a quality hold.
What happens when one OEM is most of my revenue?
Concentration is the normal condition of a Tier 2 or Tier 3 supplier. You win a program, you tool for it, you build capacity around it, and that customer becomes half your book. Funders think about concentration the opposite way, because a single counterparty failure takes the whole facility with it, and most set a default limit well below where a manufacturer actually operates.
Raise it in the first conversation rather than discovering it at closing. The questions are concrete: what is your default concentration limit as a percentage of the facility, will you underwrite above it for a well-rated OEM, what evidence would you need, and what happens to my availability if that customer grows from 45% to 65% of my billings next year. A funder with manufacturing experience has done this before and will discuss a specific limit for a specific customer. A funder quoting a flat policy limit is telling you the facility will shrink exactly as you grow.
Ask also what happens on the downside. If the OEM slows from 60 to 85 days, does the invoice fall out of eligibility on an aging trigger, and at what day? Aging ineligibility is a quiet way for a facility to contract at the worst possible moment, and manufacturers with long-paying OEMs are the most exposed to it.
There is a related question about who the obligor really is. Many Tier 2 suppliers invoice a division, a plant or a procurement entity rather than the parent, and the credit that matters is the one that actually pays. Ask which legal entity the funder will set the limit against, whether a parent guarantee or a corporate rating can lift it, and whether separate divisions of the same customer are aggregated into one limit or treated as distinct exposures. Agreeing that before closing avoids a second round of diligence in the middle of a program ramp.
The last concentration question is about your supply side, because PO financing introduces one. If a single mill or a single offshore supplier makes everything you buy for an order, the funder is exposed to that supplier performing as much as to your customer paying. Expect questions about supplier history, alternative sources and what happens to the financed deal if a shipment is late or rejected on inspection, and treat a funder who asks them as better prepared rather than more difficult.
What should I ask before I sign?
Bring a representative customer purchase order, your largest customer's terms and conditions, and a supplier quote with the lead time on it. These questions are much more productive with those three documents present.
- Can you finance my supplier purchase orders and the resulting receivables under one agreement, and what is the conversion event?
- How do you pay my suppliers — direct wire, deposit and balance, letter of credit — and which have you done before?
- My material lead time is X weeks and my build is Y weeks. Show me the sizing and the duration cost in dollars for a typical order.
- Is tooling, NRE or fixture cost fundable, and if not, how do other clients handle it?
- Do my customer's acceptance and first-article clauses delay eligibility, and do you advance at shipment or at acceptance?
- How are partial shipments and releases against a blanket PO treated?
- What is your concentration limit, and would you underwrite above it for my largest OEM?
- At what age does an invoice become ineligible, and what happens if my OEM slows to 85 days?
- Can you invoice and verify through my customer's supplier portal, or do you need something outside it?
- I have an equipment loan with a blanket filing — have you done an intercreditor agreement with that kind of lender before?
