Why PO & contract finance matters for engineering

Engineering projects often require significant up‑front spend on materials, prefabricated components, specialist labour and plant hire. Contracts can include staged progress payments, retention amounts and long lead times for supplier deliveries. That gap between spending to fulfil a purchase order or contract and receiving payment is where PO and contract finance steps in — helping firms deliver projects on time, take on larger or more complex work and preserve cash for day‑to‑day operations.

What is purchase order & contract financing?

Purchase order financing is a short‑term funding solution that lets a supplier or contractor get funds to fulfil a specific customer order. Contract finance (also called mobilisation or advance against contract) provides cash at the start of a contract to help mobilise labour, buy materials and meet early costs.

These products are distinct from invoice finance (which unlocks cash from already raised invoices) and asset finance (which funds equipment purchases). Importantly, UK Business Loans is an introducer — we do not lend money but connect businesses with specialist lenders and brokers who can help arrange finance.

How PO / contract finance works — step by step

Here’s a typical lifecycle for PO/contract finance on an engineering job:

1. Client issues a purchase order or signs a contract with the engineering firm.
2. The contractor seeks funding to buy materials or mobilise work. They submit the PO/contract and supplier quotes to a PO/contract funder or broker.
3. The lender assesses the customer’s creditworthiness (the end client matters) and supplier terms.
4. If approved, the funder either pays suppliers directly (supplier‑pay model), pays the contractor (contractor‑pay model) or provides a facility to draw against.
5. The contractor delivers work and raises progress invoices per the contract schedule.
6. The lender is repaid from progress payments, invoice finance, or on contract completion (sometimes with retention reserve arrangements).

Worked example

Example: A contractor wins a £300,000 mechanical services package (HVAC installation). Suppliers require a 30% deposit (£90,000) to order long‑lead items, plus early mobilisation costs of £40,000.

• The contractor approaches a PO financier and supplies the customer’s PO, supplier quotes and their cashflow forecast.
• The financier agrees to pay suppliers directly for the deposit and provides a mobilisation advance of £40,000 to the contractor.
• When the contractor issues the first progress claim (e.g., £120,000), part of the payment is used to repay the PO financier plus fees and interest; remaining funds return to the contractor.

What lenders usually require

• Signed PO/contract and client contact details
• Supplier quotes/invoices and delivery schedules
• Company management accounts and bank statements
• Project cashflow and progress payment schedule
• Director IDs and basic credit checks
• Details of retention and bonding (if applicable)

Types of finance used on engineering projects

Common solutions include:

• Purchase order finance — funds tied directly to a specific PO; can be supplier‑paid or contractor‑paid.
• Contract / mobilisation loans — short‑term advances to start a contract before progress payments arrive.
• Supply chain finance — finance that pays suppliers earlier, often using the buyer’s credit profile.
• Invoice finance & factoring — accelerates cash from raised progress invoices.
• Performance & retention bonds — guarantees required by clients that can be provided by specialist providers (sometimes funded).
• Asset & equipment finance — for purchasing plant and machinery used on the project.

Eligibility & documentation: what engineering firms should prepare

Typical eligibility considerations:

• Contract or PO value (many funders work from around £10,000 upwards).
• Counterparty strength — lenders prefer contracts with strong or public sector clients.
• Clear staged invoicing and a predictable payment schedule.
• Company trading history, turnover and cashflow outlook.

Documents to prepare:

• Signed PO/contract and any subcontract terms
• Supplier quotes and delivery lead times
• Management accounts (latest 12–24 months where available)
• Recent bank statements and VAT returns (if applicable)
• Project programme and cashflow forecast

Tip: clear, well‑staged contracts and finance‑friendly invoicing (progress claims with defined milestones) speed approvals and reduce costs.

Costs, pricing and risks

Costs vary by product and provider. Typical components include:

• Interest or discount rate on advanced funds
• Arrangement or facility fees (one‑off)
• Supplier payment fees if the funder pays suppliers directly
• Retention or reserve holdbacks to cover client retention

Typical headline pricing might range from mid‑single digit fees for simple supplier finance up to higher rates for riskier contracts — exact costs depend on client creditworthiness, contract size, retention and bond needs. Always request a full cost breakdown.

Key risks:

• Client non‑payment or disputes delaying repayment to the funder
• Early contract termination or scope change
• Security requirements (charges over assets or invoices)
• Supplier relationship impacts if funder pays suppliers directly — maintain clear communication

Choosing the right lender or broker for engineering PO finance

Select a partner with proven experience in engineering and construction finance. Important factors:

• Sector knowledge — funders who understand staging, retention and bonding
• Preferred funding model (pay supplier directly vs advance to contractor)
• Ability to fund retentions or provide supported bonds
• Speed of decision and flexibility on documentation

Ask prospective funders:

• Which portion of the PO will you fund and how will you pay suppliers?
• Do you hold reserves for retention? How large?
• What checks do you perform and how long will an approval take?
• Do you provide bonds or work with bonding partners?

Mini case study (anonymised)

A Midlands engineering contractor won a £420,000 contract to install plant‑room equipment. Suppliers wanted 25% deposits and the project had 8‑week lead times. The contractor used contract finance arranged through a specialist broker introduced via UK Business Loans. The funder paid deposits direct to suppliers and provided a mobilisation advance. The project completed on schedule and the contractor repaid the facility from staged progress claims, retaining working capital for other operations.

Practical tips & applicant checklist

• Prepare a clear project cashflow and staged invoicing schedule.
• Collect supplier quotes and confirm lead times in writing.
• Ensure the client’s payment terms and contact details are on the contract.
• Know retention and bonding requirements up front.

Frequently asked questions

Will purchase order finance affect my credit score?

Submitting an enquiry via UK Business Loans does not affect your credit score. Individual lenders or brokers may perform credit checks if you progress an application — you will be told in advance.

How quickly can I get funds?

Timescales vary. Simple PO facilities that fund supplier deposits can be arranged in a few days; larger contract facilities or bonding solutions may take longer. Our partners typically respond within hours of an enquiry.

Can small/medium engineering firms access PO finance?

Yes — many specialist funders work with SMEs on contracts from around £10,000 upward. The client’s creditworthiness and contract terms are key factors.

What happens if the client delays payment?

Delays create risk. Lenders mitigate this with reserves, retention holds or by linking with invoice finance. If a client’s payment is late, funders will work through recovery options agreed in the facility terms.
