Do you support invoice finance for OEM, Tier 1, and Tier 2 supply chains?

Q: Do you support invoices issued to large OEMs like JLR, Rolls-Royce, Airbus, Siemens, or BAE Systems?

Yes. Many providers in our network fund receivables to major OEMs and Tier 1s, subject to debtor approval and contract terms. Appetite and limits are set by each provider.

Q: Can you support export invoices to overseas OEMs and Tier 1s?

Yes. Selected providers fund export debt, often with credit insurance. Jurisdiction, currency, and Incoterms are considered during assessment.

Q: What about milestone or progress billing?

Some funders support stage invoices where acceptance is clear and evidenced. Documentation, audit trails, and contract clarity are essential.

Q: Can invoice finance work alongside supply chain finance (reverse factoring)?

Sometimes. With appropriate carve-outs and clear communication, both can co-exist. Your provider will explain how assignments and early payment programmes interact.

Q: Do you support Tier 2 suppliers with high buyer concentration?

Yes. Concentration is common and can be fundable. Providers will set limits and may seek additional comfort based on payment behaviour and reporting.

Q: Are tooling invoices, consignments, and call-off schedules fundable?

Tooling is often excluded, though exceptions exist with strong evidence. Consignment and call-off can be fundable once delivery and acceptance are confirmed.

Q: How quickly could we receive funding after approval?

Once onboarded, advances are often made within 24–48 hours of submitting eligible invoices, subject to verifications and facility type.

Q: Will my customer know?

In factoring, customers are usually notified and payments go to a trust account. In confidential invoice discounting, you typically manage collections without disclosure.

How invoice finance supports OEM and Tiered supply chains

Invoice finance releases working capital tied up in unpaid invoices, typically advancing a percentage of invoice value soon after issue. That can help suppliers trading on 45–120 day terms to OEMs and large Tier 1 buyers maintain production, pay staff, and fund materials. It is especially useful where payment cycles lengthen due to call-off schedules, quality approval, or goods acceptance milestones.

Common structures include factoring (disclosed to the customer), confidential invoice discounting (undisclosed servicing by you), and selective or spot invoice finance (fund a few invoices when needed). Some providers also offer export invoice finance for overseas OEMs and supply chain finance or reverse factoring for buyer-led programmes. The right route depends on your customers, contracts, and operational workflows.

In engineering and manufacturing supply chains, lenders look closely at debtor quality, concentration, and potential dilutions. They assess creditworthiness of buyers such as automotive OEMs, aerospace primes, rail integrators, and Tier 1 assemblies providers. They will also consider warranty terms, returns, set-off risks, framework agreements, and evidence of delivery or acceptance.

Typical use cases we see

Automotive: Tier 2 component suppliers invoicing Tier 1s with 60–90 day terms.
Aerospace: AS9100-approved machine shops invoicing primes subject to acceptance.
Industrial: Fabricators on call-off POs to OEM production plants and MROs.
Electronics: PCB assemblers supplying Tier 1 integrators with batching and PPAP.

If your business fits within engineering or manufacturing, see our sector page on engineering business finance for broader funding options alongside invoice finance. We can also help blend solutions, such as asset finance for machinery plus invoice finance for cash flow. Our role is to introduce, so you can compare structures that suit your contracts.

Who we can help and what providers typically require

We support UK-registered limited companies and LLPs that trade B2B and issue verifiable invoices to OEMs or Tier 1 and Tier 2 buyers. Providers generally prefer established firms with predictable ledgers and robust processes around delivery notes, GRNs, and acceptance. Start-ups and sole traders are not currently supported via our platform.

Providers usually ask for a recent aged debtor report, sample invoices, customer contracts or framework POs, and details of any warranties, rebates, or contra arrangements. They may also request bank statements, management accounts, and your top customer concentrations. Where export debt is involved, they will want to understand Incoterms, jurisdiction, and currency exposure.

Advances are commonly offered against approved debtors, often between 70% and 90% of invoice value, depending on profile. The remainder is released on payment, less fees and charges. Eligibility is always subject to provider due diligence, including checks on the debtor, your operations, and any sector-specific risks such as high return rates or complex milestone billing.

Key considerations for OEM and Tier suppliers

Buyer concentration: High reliance on one OEM or Tier 1 is common and can be fundable.
Documentation: Clear proof of delivery or acceptance helps minimise disputes and dilutions.
Terms: Extended terms (60–120 days) are typical and can be accommodated in structures.
Contract risks: Set-off, tooling amortisation, and rebate clauses need careful review.

Some lenders can fund export receivables to major overseas OEMs with credit insurance. Others may focus on UK-only debt for speed and simplicity. Our AI matching considers these nuances to connect you with providers aligned to your ledger profile and sector.

Cost, risk, and transparency — fair, clear, and not misleading

Invoice finance pricing varies by facility type, debtor quality, and volumes. Costs typically comprise a service fee and a discount rate or margin over a base rate, along with any transaction or arrangement fees. We cannot guarantee the lowest rate, and all quotes are indicative until a provider completes due diligence.

There are risks and obligations to understand before proceeding. Facilities may be with or without recourse, and you remain responsible for performance under your contracts. Disputes, credit notes, returns, and contra set-off can reduce available funding and increase costs.

Providers may apply concentration limits, sector caps, or debtor credit limits that affect your usable headroom. Some facilities are disclosed to your customers; others are confidential and serviced by your team. We will always encourage transparent discussions so you can compare like-for-like terms clearly.

What affects your final terms

Customer mix and credit strength of OEMs and prime contractors.
Historic dispute rates, dilutions, and promptness of payments.
Export exposure and availability of trade credit insurance.
Operational controls, ERP integration, and audit readiness.

The process — from Quick Quote to decision in principle

Step 1: Complete a Quick Quote. Share basic details about your business, invoice volumes, top customers, and payment terms. It takes a few minutes and there is no obligation.

Step 2: AI matching. Our system analyses your profile and identifies providers active in OEM and Tiered supply chains who align to your requirements. We consider sector appetite, facility types, and debtor exposure.

Step 3: Introductions. We introduce you to lenders or brokers who can discuss options, request documents, and offer an eligibility view. You can speak with more than one provider before deciding.

What to prepare for faster outcomes

Aged debtor ledger and top 10 customer exposures.
Sample invoices, delivery notes, and acceptance certificates.
Framework agreements, call-off POs, and warranty or rebate terms.
Recent bank statements and management accounts.

Timelines vary, but many providers can move from eligibility to a decision in principle quickly once documents are complete. Settlement and go-live depend on facility type, legal documents, and any notice needed with your existing funder.

If you’re supplying engineered components, assemblies, or fabricated parts, you can also explore asset funding alongside receivables. Visit our page for engineering business loans to consider equipment finance, refinance, and cash flow solutions in one plan.

FAQs and key takeaways for OEM, Tier 1, and Tier 2 invoice finance

Do you support invoices issued to large OEMs like JLR, Rolls-Royce, Airbus, Siemens, or BAE Systems?

Yes, many providers in our network actively fund receivables to major OEMs and Tier 1s, subject to debtor approval and your contract terms. Buyer credit appetite varies and is set by each provider. We will match you to funders with relevant experience and capacity for your debtor list.

Can you support export invoices to overseas OEMs and Tier 1s?

Yes, some providers fund export debt and may use credit insurance to manage risk. Jurisdictions, currencies, and Incoterms will be considered during assessment. Providers will confirm any additional documentation required for cross-border receivables.

What about milestone or progress billing in aerospace and capital goods?

Certain funders can support stage invoices where acceptance criteria are clear and evidenced. Documentation and audit trails are critical for approval. Where milestones are complex or subject to extensive acceptance, specialist structuring may be needed.

Can invoice finance work alongside supply chain finance (reverse factoring)?

Yes, in some cases invoice finance and buyer-led SCF can co-exist with appropriate carve-outs. Your provider will confirm how competing assignments or early payment programmes interact. Clear communication with buyers helps avoid double funding risks.

Do you support Tier 2 suppliers with high buyer concentration?

Yes, concentration is common in Tiered supply chains and can still be fundable. Lenders will set appropriate limits and may require additional comfort. Good reporting and predictable payment behaviour help secure stronger terms.

Are tooling invoices, consignments, and call-off schedules fundable?

Tooling recoveries are often excluded, but some providers may consider them with robust evidence. Consignment stock and call-off invoicing can be fundable once delivery and acceptance are confirmed. The specifics depend on your contracts and ERP evidence.

How quickly could we receive funding after approval?

Once onboarded, many businesses receive advances within 24–48 hours of submitting eligible invoices. Timelines depend on facility type, verifications, and debtor notifications. Your chosen provider will set service levels and processes.

What documents should we have ready?

Prepare your aged debtor ledger, sample invoices, GRNs, acceptance notes, contracts, and recent financials. For exports, include shipping evidence and insurance details if applicable. Having these ready speeds up decisions and onboarding.

Will my customer know?

In factoring, notices are typically sent and payments go to a trust account. In confidential invoice discounting, you usually manage collections and customers need not be notified. Your provider will explain disclosure requirements for your facility.
