Invoice Factoring and Working Capital Finance for Startups

A company signs a large enterprise customer, delivers the work, and issues an invoice on ninety-day payment terms. Meanwhile payroll runs every two weeks and suppliers want paying in thirty days.

The company is profitable on paper and running out of cash. This is the working capital gap, and it is one of the most common reasons otherwise healthy businesses fail.

It is also a solved problem with a set of purpose-built products — none of which is equity. This guide covers what those products are, how they are actually priced, what lenders underwrite, how to work out whether a facility pays for itself, and which products to avoid.

1. The Key Insight: They Underwrite Your Customers

Conventional lenders assess your creditworthiness and frequently decline. Receivables financiers assess the creditworthiness of the companies that owe you money.

That inversion is why an unprofitable startup billing large, established enterprises can access working capital finance readily. Your customers are good credits. The financier is buying exposure to them, not to you.

The consequence is direct: the quality of your customer base determines the availability and price of this capital. A company invoicing investment-grade enterprises gets better terms than one invoicing other startups, regardless of which company is healthier.

2. The Products

Invoice factoring

You sell the invoice to a factor at a discount. They advance most of the face value immediately — commonly 80% to 90% — collect from your customer, and remit the balance less their fee.

Notification factoring means your customer is told to pay the factor. Confidential factoring means they are not, and you continue collecting. Notification is cheaper; confidential preserves the relationship and avoids signalling financial stress.

Invoice discounting

You borrow against the invoices rather than selling them. You keep the customer relationship and collection process; the lender takes security over the receivables. Usually confidential and usually cheaper than factoring, and typically requires better financial controls.

Receivables line / asset-based lending

A revolving facility sized by a borrowing base formula applied to eligible receivables. Draw, repay, redraw. More flexible and generally cheaper at scale. The borrowing base mechanics are covered in our guide to private credit, and the eligibility definitions matter more than the rate.

Purchase order financing

Funds the cost of fulfilling a confirmed order before you invoice. Used by companies that must pay a manufacturer before they can deliver. Expensive, and it solves a problem nothing else does.

Inventory financing

Borrowing against stock. Lower advance rates than receivables, because liquidation value is much less certain than a receivable from a solvent customer.

Supply chain finance

Arranged by a large buyer, allowing their suppliers to be paid early at a rate based on the buyer's credit rather than the supplier's. If you sell to a large enterprise, ask whether they operate a programme — it is frequently the cheapest working capital available to you and costs nothing to ask about.

Merchant cash advance — treat with real caution

An advance repaid through a fixed percentage of daily card receipts or direct debits from your account. Fast, minimal underwriting, and very expensive.

Specific risks: daily or weekly debits that continue regardless of your cash position, effective annualised costs that can be extremely high, personal guarantees, and — in some agreements — provisions that make enforcement fast and difficult to contest. Stacking multiple advances is a well-documented route to insolvency.

This is a last resort, not a working capital strategy. If you are considering one, exhaust every other option first.

3. How Pricing Actually Works

The most important thing to understand about this market: rates are quoted per period, not per year.

A factor quoting “2%” typically means 2% per 30 days. That is roughly 24% annualised. A quote of 3% for the first 30 days plus 1% for each additional 10 days becomes considerably more if your customer pays slowly.

Always convert to an annualised rate before comparing. Providers rarely present it that way, and the difference between a headline number and the true cost of capital is where confusion — and occasionally exploitation — lives.

Components to identify:

• Advance rate — what percentage you receive up front. The remainder is held back until your customer pays.
• Discount or factoring fee, per period
• Service or administration fee, sometimes monthly regardless of usage
• Minimum volume commitments and fees for falling short
• Setup, due diligence and audit fees
• Termination fees and notice periods — frequently long, and a real constraint on switching

4. Working Out Whether It Pays for Itself

The test is not whether the rate looks high. It is whether the cash arriving earlier produces more value than the fee costs — and that is a specific calculation, not a judgement call.

Start with your gross margin. If a facility costs the equivalent of two to three percent of invoice value per month and your gross margin is fifteen percent, the arithmetic is tight and you need the cash to do real work. If your gross margin is seventy percent, the same facility is comfortably affordable. A business whose financing cost approaches its gross margin is working for the financier, and that is the single clearest signal to stop.

Then ask what the cash actually buys. There are three honest answers and one dishonest one.

• It funds the next order you could not otherwise take. The cleanest case — the margin on incremental business you would have declined pays for the facility several times over.
• It replaces more expensive capital. Also clean. Equity sold at seed valuation to cover a ninety-day payment gap is far more expensive than any factoring fee, as our guide to non-dilutive capital sets out.
• It lets you take an early-payment discount from your own suppliers. Frequently overlooked, and sometimes the discount alone covers most of the financing cost.
• It covers a shortfall between revenue and costs. This is the dishonest one. Financing a timing gap is sound; financing a loss accelerates it, and the facility will run out at exactly the point the underlying problem becomes unavoidable.

Model the slow-payment case. Because fees accrue per period, the cost is a function of how long your customers actually take, not of the terms printed on the invoice. Run the numbers at your genuine average collection period rather than your stated terms — the gap between the two is usually substantial and it is entirely at your expense.

Finally, count what you get back. Factoring includes collections, which for a company without a credit control function is real work removed. That has a value, and it belongs in the comparison alongside the fee.

5. Recourse Versus Non-Recourse

Recourse means if your customer does not pay, you buy the invoice back. You retain the credit risk. Cheaper.

Non-recourse means the factor absorbs the loss if your customer becomes insolvent. More expensive, and the protection is narrower than it sounds — non-recourse typically covers insolvency, not a customer withholding payment because of a dispute about your work.

Read the definition of what triggers recourse. Most factoring is recourse in practice for anything other than outright customer failure, which is a fact worth knowing before you rely on the protection.

6. What Qualifies, and What Does Not

Works well:

• B2B invoices to creditworthy business or government customers
• Work already completed and accepted
• Clean, undisputed invoices with clear payment terms
• A reasonably diversified customer base

Problematic or excluded:

• Consumer receivables — different regulatory regime entirely
• Progress or milestone billing where the work is incomplete
• Contracts prohibiting assignment. Check your customer agreements before assuming you can finance them — anti-assignment clauses are common and can block the whole arrangement.
• Heavy customer concentration. Financiers cap exposure to any single debtor, so a company with one dominant customer finances less than expected.
• High dilution — the industry term for credit notes, disputes and short payments. Consistent dilution makes your receivables less financeable and is scrutinised closely.
• Aged receivables. Invoices past 90 days typically fall out of eligibility entirely.

Government receivables deserve a note: they are excellent credit, but assigning claims against a government body follows a specific statutory process. Financiers who work with government contractors know it; general factors may not. This matters for anyone in defense or government contracting, where slow payment is structural.

7. The SaaS Version

Software companies have a different but related problem: customers who pay monthly while you would rather have the annual value now.

Options:

• Discount for annual prepayment. The simplest and cheapest solution, and frequently overlooked. Compare the discount you would offer against the cost of financing — a 10% annual discount is usually cheaper than borrowing.
• Recurring revenue financing, where a provider advances against contracted subscription revenue — a specialised form of receivables finance sized on retention and contract quality.
• Revenue-based financing, repaid as a share of revenue rather than on a fixed schedule. Our comparison with equity funding covers the trade-offs.

8. When It Is Right — and When It Is Not

Right when:

• The gap is genuinely timing — you are profitable on the work, just paid late
• Growth is constrained by cash tied up in receivables
• You need to fund a large order before you can deliver it
• The cost is comfortably below the margin on the work

Wrong when:

• The underlying business loses money on each sale. Financing accelerates losses.
• You are using it to fund operating deficits rather than a timing gap
• The cost exceeds your gross margin — at which point you are working for the financier
• You are stacking multiple advances, which is the clearest single warning sign in small business finance

9. Negotiating Points

• Advance rate — a few percentage points is real cash
• Eligibility definitions — which invoices count, and the concentration limits. This determines what you can actually draw.
• Confidential rather than notification, where you can get it
• No personal guarantee, or a narrowly limited one
• Termination notice — twelve-month notice periods are common and restrictive
• Minimum volume commitments — avoid committing to volumes you may not hit
• Interaction with existing lenders. If you have venture debt with a blanket lien, your lender must consent to a receivables financier taking priority over your accounts receivable. Handle this before signing.

Frequently Asked Questions

Will our customers know we are factoring?

Under notification factoring, yes — they are instructed to pay the factor. Under confidential arrangements, generally not. Some founders worry this signals distress; in many industries it is entirely routine and attracts no comment at all.

How fast can we get funded?

Setup typically takes one to three weeks including customer verification. After that, individual invoices frequently fund within 24 to 48 hours. Speed is one of the genuine advantages of this category.

Does this hurt our next equity round?

Not if used sensibly. Investors understand working capital finance and prefer it to equity funding a timing gap. What concerns them is a company relying on very high-cost financing to survive, or stacked advances — both of which surface immediately in diligence.

Can we factor only some invoices?

Depends on the agreement. Spot factoring lets you choose individual invoices and costs more per invoice. Whole-turnover arrangements require you to put all qualifying receivables through the facility and price better. Know which you are signing.

What is dilution in this context?

Not equity dilution — the industry uses the term for reductions in the value of receivables from credit notes, disputes, discounts and short payments. High dilution reduces your advance rate and can make a facility unavailable, so it is worth understanding your own figure before you approach anyone.

What happens if a customer simply refuses to pay?

Under a recourse facility you buy the invoice back, and you are then chasing the customer yourself with the cash already spent. Under non-recourse you are usually still exposed, because a refusal based on a dispute about your work is not the same as insolvency and is generally outside the cover. The practical protection is upstream: clean invoices against accepted work, clear acceptance criteria in the contract, and not financing anything a customer has already queried. Financiers watch dispute rates closely for exactly this reason.

Can we finance invoices to customers outside our country?

Yes, though it is a specialist product. Export factoring exists and works, with the financier either taking the foreign credit risk directly or working through a correspondent in the customer's country. Expect lower advance rates, more documentation and attention to currency risk and enforceability. Credit insurance is frequently used alongside. If a meaningful share of your receivables are cross-border, choose a provider who does this routinely rather than one adding it as an accommodation.

Does factoring appear on our balance sheet?

It depends on the structure, and it is worth asking your accountant before signing. True non-recourse factoring may qualify for derecognition, removing the receivable and improving the presented position. Recourse arrangements and invoice discounting generally remain on balance sheet as a receivable with a corresponding liability. Either way, it is disclosed, and investors and lenders will see it — the accounting treatment changes how it looks, not whether anyone knows.

How do we exit a facility we no longer need?

Read the termination clause before you sign, because this is where the friction sits. Notice periods of six to twelve months are common, minimum-term commitments are standard, and early exit fees can be substantial. There is also a practical unwind: outstanding invoices must run off or be repurchased, and if the arrangement was notified, customers need to be told to pay you again. Plan the exit at the point you plan the entry, particularly if you expect a funding round to make the facility unnecessary.

The Bottom Line

A working capital gap is a financing problem with purpose-built products, and equity is the most expensive possible solution to it.

Convert every quoted rate to an annualised figure before comparing. Test the cost against your actual gross margin and your actual collection period. Check your customer contracts for anti-assignment clauses. Ask your largest customers whether they run a supply chain finance programme. And treat merchant cash advances as a last resort rather than a tool.
