Invoice Finance for Manufacturing: Closing the Order-to-Cash Gap

The order-to-cash gap that defines manufacturing cash flow

Manufacturing has a working-capital problem that service businesses never meet. You spend real cash at the very start of a job and see nothing back for months. Raw materials and components are bought and paid for in week one. Labour, energy, and machine time are consumed across the build. The finished goods only ship when the order is complete, and only then can you raise an invoice. Your business customer then takes their contractual 30, 60, or 90 days to pay.

Stretch that across a typical order and the gap is stark. Cash goes out at the beginning of the cycle. Cash comes back at the very end. In between sits a long stretch where materials are paid for, the job is half-built, and none of it is billable yet. Accountants call this the order-to-cash cycle. On the shop floor it feels like permanently funding next month's orders out of last month's margin.

Two features make manufacturing worse than most sectors. First, the input cost is front-loaded: steel, resin, boards, castings, and bought-in parts are paid for before a single unit is sold. Second, the production lead time is long, so value builds up as work in progress (WIP) that you cannot invoice against. A £250k order might tie up £100k of materials in week one and take ten weeks to build before an invoice can be raised at all. Understanding exactly where in that cycle invoice finance helps, and where it does not, is the whole point of this guide.

Where invoice finance fits a manufacturer, and the one phase it cannot fund

Invoice finance advances cash against your unpaid B2B sales invoices. When you raise an invoice, the provider releases a large slice of its value straight away, commonly up to 90%, rather than making you wait the full payment term. The remaining balance, less fees, follows when your customer settles. For a manufacturer, that turns a 60 or 90 day wait after despatch into cash within a day or so of invoicing.

That is genuinely valuable, because the output side of a manufacturing cycle (invoice raised, waiting to be paid) is exactly what invoice finance is built for. Substantial, well-documented invoices to solid trade customers are the ideal asset for an asset-based lender.

Here is the honest limitation the sales pitches skip. Invoice finance only reacts to an invoice. It does nothing for the pre-invoice phase, when raw materials are bought and the job is being built but nothing is billable yet. In our £250k example, that is weeks one to ten, precisely when your cash is most stretched. WIP is not an invoice, so it cannot be financed by an invoice line. Any provider that implies otherwise is glossing over how the product works.

The practical answer is to fund the two halves of the cycle with two different tools: trade or stock finance for the input phase, and invoice finance for the output phase. We come back to how they stack below.

Factoring, invoice discounting, or export factoring for manufacturers

There are three shapes of facility a manufacturer will be offered, and the right one depends on the size and reach of your order book.

• Factoring (disclosed). The provider advances against your invoices and also runs credit control, chasing your customers for payment in the provider's name. Your customers are told to pay the provider. This suits smaller manufacturers who would rather not run a collections function.
• Confidential invoice discounting (CID, undisclosed). You keep collecting in your own name and your customers never know a facility is in place. You run your own credit control. This suits larger manufacturers with a capable finance team and a stronger balance sheet, who want to protect the customer relationship. Lenders reserve CID for companies with the turnover, systems, and covenant to manage their own ledger.
• Export factoring or export discounting. A specialist version for overseas sales, handling foreign currencies, longer international terms, and the extra risk of collecting abroad, often with credit insurance behind it. If a meaningful slice of your output ships to export customers, you need a facility that can fund those invoices, not just your domestic ones.

Most manufacturers grow from factoring into discounting as they scale. If you export, treat export capability as a hard requirement when comparing facilities. For a full breakdown of the two core products, see our guides to invoice factoring and confidential invoice discounting, and the parent invoice finance guide for how advance rates, service fees, and the discount margin combine.

Worked example: financing a £250,000 order across a 20-week cycle

Take a limited-company manufacturer that wins a £250,000 order (excluding VAT) from a trade customer on 60-day terms. The build takes ten weeks. Here is how the cash moves without finance, and then with an invoice-finance line on the output side.

Point in cycle	What happens	Cash effect (unfunded)
Week 1	Raw materials and bought-in parts paid for	£100,000 out
Weeks 1 to 10	Labour, energy, machine time consumed; value builds as WIP	Further cash out, nothing billable
Week 10	Order complete, shipped, invoice raised for £250,000	Still £0 in
Week 20	Customer pays on 60-day terms	£250,000 in

Unfunded, the company is out of pocket from week one to week twenty, roughly a five-month gap, while it has already paid for the next set of orders. That is what starves growth: every won order consumes cash the business needs for the following one.

Now add invoice finance on the output side. The moment the £250,000 invoice is raised in week 10, an 85% advance releases £212,500 the next day, rather than in week 20. The remaining £37,500, less the service fee and discount charge, arrives when the customer settles. The five-month gap on the output half of the cycle collapses to roughly a day.

Cost of financing that single invoice for the ten weeks it would otherwise sit unpaid, on an illustrative 1.5% service fee plus a discount margin of around 2.5% over base, works out at a few thousand pounds. Set that against the ability to accept the next order without a cash crunch and, for most growing manufacturers, the arithmetic is straightforward. Rates are illustrative only; the panel returns real quotes on your ledger.

Funding the pre-invoice phase: raw materials and WIP

The worked example makes the limitation concrete. Invoice finance closed the week 10 to week 20 gap, but the company was still fully exposed from week 1 to week 10, when materials were paid for and the job was being built. That input phase is where manufacturers most often run dry, and it needs a different product because there is no invoice to finance.

The usual answers, often stacked alongside the invoice line, are:

• Trade finance or stock finance. The lender pays your suppliers directly against confirmed purchase orders, funding the materials before you have made or sold anything. This directly addresses the week-one cash outflow.
• A revolving credit facility. A flexible line you draw down as materials are bought and repay as invoices are paid, so you only pay interest on what is drawn. See our guide to working capital finance for how to match the product to the cause of the gap.
• A short-term working-capital loan. A lump sum to cover a known seasonal or contract-driven build, repaid over a few months.

Many asset-based lenders will combine a trade-finance line for the input phase with an invoice-finance line for the output phase, giving you cash across the full cycle rather than only after despatch. When you talk to the panel, describe both halves of your cycle so the facility is structured around the whole order-to-cash journey, not just the visible debtor book.

Pairing invoice finance with asset finance and full expensing

Manufacturing is capital-equipment heavy. The plant that does the work (CNC machines, injection-moulding lines, presses, packaging lines) is expensive and needs periodic replacement. Trying to buy it out of the same cash you use to fund materials is what forces many manufacturers to under-invest. This is where asset finance sits alongside invoice finance, solving a different problem.

Asset finance (hire purchase or lease) spreads the cost of new plant over its working life instead of taking the hit up front. Crucially for a limited company, buying new, unused, main-rate plant on hire purchase can still qualify for full expensing, the permanent 100% first-year corporation-tax deduction on qualifying new plant and machinery. You own the asset at the end of the agreement, you spread the cash cost, and you take the entire tax relief in year one. With corporation tax at 25% for larger companies (and an effective 26.5% in the marginal-relief band between £50,000 and £250,000), a £120,000 machine bought on hire purchase can shelter around £30,000 of tax in the first year.

The Annual Investment Allowance (£1,000,000, unchanged) covers most manufacturers who prefer a simple 100% write-off across both main-rate and special-rate assets. We do not restate the tax mechanics here. For the detail, read our guides to full expensing capital allowances and the Annual Investment Allowance, and for the product side see the asset finance guide and equipment and machinery finance. The takeaway for cash flow is simple: keep invoice finance for the debtor book and asset finance for the plant, and do not drain one to pay for the other.

Eligibility for a manufacturing company

To be introduced to the panel for an invoice-finance facility, your business needs to be a UK limited company or LLP selling to other businesses on credit terms and raising proper sales invoices. Beyond that, lenders assess:

• Turnover and trading history. A track record and a reasonable annual turnover support both approval and a higher advance rate. Confidential discounting in particular is reserved for companies with the scale and systems to run their own collections.
• The quality of the debtor ledger. Well-aged invoices, reliable trade customers, and few disputes or credit notes support the top of the 80 to 90% advance range. A messy or heavily contested ledger pulls the advance down.
• Customer spread. A range of solid trade customers is stronger than one dominant buyer. Concentration on a single customer can trigger a cap on that debtor (see below).
• Invoice type. Straightforward sale-of-goods invoices are easiest. Where you bill in stages or against milestones, tell the lender so the facility is set up correctly.

Company borrowers only. The finance introductions on this page are for UK limited companies and limited liability partnerships borrowing for business purposes. We introduce your company to a panel of commercial-finance brokers; we are not a lender and do not give regulated credit advice. If you are a sole trader, an individual, or borrowing for personal or household purposes, this service is not for you, and you should speak to an FCA-authorised consumer-credit firm.

What to watch as a manufacturer

A few sector-specific points decide how well a facility works and how much it really costs.

• Customer concentration. Many manufacturers depend on one or two large original-equipment or wholesale relationships. Lenders manage that risk with a concentration limit, capping how much of one debtor they will fund. A broader customer base lifts your blended advance rate.
• Disputes and credit notes. Quality claims, short deliveries, and returns generate credit notes that reduce the value of a financed invoice. A pattern of disputes makes lenders cautious and can lower advances. Tight quality control protects your funding as well as your reputation.
• Staged billing and part-shipments. If you invoice in stages or ship part-orders, make sure the facility recognises those invoices cleanly. Ambiguity over what has been delivered slows funding.
• Export terms and currency. Overseas invoices carry longer terms and collection risk. Confirm export capability and whether credit insurance is bundled before committing.
• Termination notice and trailing commission. As with any factoring or discounting agreement, check the notice period and any minimum-term or trailing-commission clauses, so an exit later does not carry an unexpected cost.

How to apply

Applying is quick if you have the right documents ready. Pull together your most recent statutory or management accounts, a current aged debtors listing, and your standard terms of trade. If you export, note the share of turnover that ships overseas and the currencies involved. If your cash pressure is really in the materials-and-build phase, say so, so the panel can consider trade or stock finance alongside the invoice line.

Then complete the form below. The first qualifying question confirms your business is a limited company or LLP, because these introductions are for incorporated borrowers only. We pass your details to our commercial-finance broker panel, who return real, exclusive quotes on a facility built around your order-to-cash cycle. If your question is about how the finance and any plant purchase are taxed and structured rather than the facility itself, we can instead introduce Holloway Davies, our accountancy team, as a secondary route. Introductions are business-to-business; we are not a lender.
