Invoice Factoring vs. a Bank Line of Credit

What is each one actually lending against?

A bank revolving line of credit is a general corporate facility. The bank is lending against the overall creditworthiness of your business — its trading history, profitability, cash flow coverage, leverage and the collateral it can take — and the facility is sized to that assessment. The receivables may be collateral, but the credit decision is about the company.

Invoice factoring is a transaction-level product. The factor buys specific invoices owed by specific customers, and the dominant question is whether those customers pay their bills on time. Your own financial statements matter far less, which is precisely why factoring reaches businesses that banks decline: early-stage companies, companies growing faster than their balance sheet, companies recovering from a loss year, and companies in sectors a given bank does not have an appetite for.

This is the root of every other difference between the two. Speed, limit, covenants, reporting and cost all follow from the question each funder is asking.

Which is cheaper?

A bank line, when you can get one. That is not a close call and it is worth saying plainly: if your business qualifies for bank credit and the limit is large enough for what you need, bank credit is the cheaper capital.

The complication is that the two are quoted in different units, which makes casual comparison misleading in both directions. Factoring is quoted as a percentage per 30 days on invoice face value. A bank line is quoted as an annual interest rate on the balance drawn. A 2% per 30 day factoring fee is roughly 24% on a simple annualised basis if you were to use it continuously all year — but most businesses do not factor continuously or factor the whole ledger, which is why the annualised figure overstates what many of them actually spend.

The honest comparison is in dollars per year against the funding you actually use, not in headline percentages.

How long does approval take, and what do they ask for?

Bank timelines are driven by credit committee process. Expect to supply two to three years of financial statements, interim figures, tax returns, a receivables and payables aging, projections, and personal financial statements from the owners. Appraisals, field exams or environmental reviews can extend the timeline further where real property or inventory is involved. Thirty to ninety days from application to funds is normal, and a decline often arrives late in that process.

Factoring diligence is narrower and faster. The factor needs your AR aging, sample invoices with proof of delivery, a customer list to run credit checks against, formation documents and EIN, a voided check and owner ID, and a UCC search. Most new accounts are approved within a few business days, with the first funding following shortly after the notice of assignment goes out.

The practical consequence is about sequencing. If you need working capital for a contract that starts in three weeks, the bank timeline cannot help you even if the bank would eventually say yes.

Which one grows with my business?

This is the difference most growing companies underestimate. A bank line is a fixed number. If you are approved for $500,000 and your sales double, you still have $500,000 until you successfully request an increase — a process that means fresh underwriting, updated financials, and a committee that may be looking at a balance sheet stretched by the very growth you are financing.

A factoring facility has no equivalent ceiling in the same sense. Capacity tracks the invoices you issue to approved customers. Doubling your invoicing to creditworthy buyers roughly doubles the cash available, without a new application, because each new invoice is simply another asset the factor can purchase.

The constraint shifts rather than disappearing: instead of a company limit, you face per-customer credit limits and concentration caps. If one buyer is most of your ledger, the factor will cap exposure to that buyer regardless of how reliably it pays. That is a real limit, but it is a limit on a single counterparty, not on your business.

• Fast-growing companies frequently outgrow a bank line within a year of getting it.
• Seasonal businesses pay for unused capacity on a line and pay only for what they factor.
• A single unexpectedly large contract can exceed a bank limit but be perfectly fundable as invoices.
• Per-customer credit limits are the real ceiling in factoring — ask what they will be before you sign.

What happens when something goes wrong?

The failure modes differ, and the difference is significant for a business under stress. A bank line is governed by covenants: minimum fixed-charge coverage, maximum leverage, minimum tangible net worth, and similar tests measured quarterly. Breaching one is an event of default even if every payment has been made on time. The bank may waive it, reprice it, reduce the line or demand repayment — and the breach typically happens in exactly the quarter the business can least afford it.

Factoring has no covenant structure to breach. The equivalent risk is at the invoice level: under a recourse arrangement, an invoice your customer does not pay within the recourse period is charged back to you, usually by offsetting against reserves or future advances. A single bad debt on a concentrated ledger can be a serious cash event, and it arrives without the warning a covenant test gives you.

There is also a reporting asymmetry. A bank reviews you quarterly and annually; a factor is watching the ledger continuously and will raise concerns about a slowing customer long before a quarterly covenant would catch it.

Can I have both at the same time?

Sometimes, but it takes deliberate structuring, because both funders want first position on your accounts receivable. A bank's blanket UCC-1 covering all assets includes accounts, and a factor cannot buy receivables that are already encumbered in first position.

Three arrangements come up in practice. The bank carves receivables out of its collateral and lends against equipment, inventory or real estate instead. The bank subordinates its interest in accounts to the factor by written agreement. Or the two funders sign an intercreditor agreement defining priority, cash flows and enforcement rights.

None of these happens informally. Expect weeks of negotiation and legal cost, and expect the bank to ask why the receivables are going elsewhere. It is more common to run one or the other, and to use factoring alongside an equipment or real-estate facility where the collateral does not overlap.

When should I switch from factoring to a bank line?

Factoring is a stage-appropriate tool for many companies rather than a permanent arrangement, and the right time to move is when you can satisfy a bank's tests without straining. Watch for these signals rather than a particular revenue number.

1. 1Two to three years of profitable, audited or reviewed statements. Banks underwrite history. A single strong year rarely carries a credit committee on its own.
2. 2Predictable working capital needs. If you can forecast peak borrowing within a reasonable range, a fixed limit stops being a constraint.
3. 3Spread customer concentration. A diversified ledger improves terms with either funder and removes the biggest single-point risk from your business.
4. 4Clean lien and tax position. Resolve or document any outstanding liens before applying. They stall bank applications more often than weak margins do.
5. 5Compare the full annual cost, not the rate. Price the bank line including unused-line and review fees against what factoring actually cost you last year. Also price the covenant risk — what happens to the business if the line is reduced in a slow quarter.
