Fixed limit versus growing facility

An overdraft gives you a set limit to dip into and is quick to use for any purpose. But the limit is fixed until you renegotiate, and — for most business overdrafts — it is repayable on demand. Invoice finance ties funding to your sales ledger: as you invoice more, the available cash rises automatically, with no fresh application. For a business whose funding need grows with turnover, that scaling is a real advantage over a static overdraft limit.

Cost and reliability

	Overdraft	Invoice finance
Limit	Fixed until renegotiated	Grows with your sales ledger
Security	Often a personal guarantee	The invoices themselves
Reliability	Repayable on demand	In place for the agreement term
Purpose	Any short-term dip	Only cash locked in B2B invoices

Overdrafts suit any small dip; invoice finance only helps if your cash is genuinely stuck in unpaid business invoices. But an overdraft's recall risk and fixed ceiling make it less dependable for a growing company. Compare structures in our invoice finance guide.

Which suits your cash cycle

If you sell B2B on credit terms and the wait to be paid is your main problem, invoice finance directly targets it and scales as you grow. If your cash dips are small, occasional and not invoice-related, an overdraft — or better, an agreed revolving line without the recall risk — is simpler. Many directors weigh invoice finance against a flexible facility rather than an overdraft: see invoice finance vs a business loan.

Frequently asked questions

Does invoice finance grow with my business?

Yes. Because funding is tied to your sales ledger, the cash available rises automatically as you invoice more, without a fresh application. An overdraft has a fixed limit that only changes when you renegotiate, so invoice finance suits a growing company better on that count.

Is an overdraft more flexible than invoice finance?

For small, occasional dips of any kind, yes — an overdraft can be used for any purpose instantly. But it is usually repayable on demand and capped at a fixed limit. Invoice finance is less flexible in purpose but scales with sales and is not recalled on a whim.

Which is cheaper?

It depends on usage. Invoice finance costs a service fee plus a discount charge that falls as customers pay faster. An overdraft charges interest on the overdrawn balance plus arrangement and review fees. Compare the total cost in pounds for your own figures rather than the headline rate.
