Cash flow is the lifeblood of any business — and gaps between invoicing and receiving payment are one of the most common causes of business stress. Two popular solutions are invoice finance and business overdrafts. Both bridge the gap, but they work very differently.
Invoice Finance: How It Works
Invoice finance (also called debtor finance or accounts receivable finance) allows you to advance 70–90% of the value of unpaid invoices — before your customers have paid.
There are two main types:
- Invoice factoring: The lender manages your accounts receivable and collects from your customers directly. Simpler to administer, but your customers know you're using a factoring company.
- Invoice discounting: You retain control of collections. The lender advances funds against invoices but doesn't interact with your customers. Requires more administration on your end.
Best for: B2B businesses with significant invoice books (trade, construction, professional services, freight). Minimum invoice book typically $50,000+.
Business Overdraft: How It Works
A business overdraft is a pre-approved credit facility attached to your business transaction account. You can draw up to a set limit and only pay interest on what you use.
Overdrafts are typically:
- Secured (against property) or unsecured (based on creditworthiness)
- $10,000–$500,000 limits
- Reviewed annually by the lender
- Available from banks and some fintech lenders
Best for: Businesses with irregular cash flow but a consistent overall trading pattern. Useful for short-term dips that self-resolve within the trading cycle.

Cost Comparison
Invoice finance: Typically 1.5–3% of the invoice value per month (discount fee), plus possible management fees. On a $100,000 invoice advancing 85% = $85,000 received, with a $1,500–$3,000 monthly fee until the invoice is paid.
Business overdraft: Interest only on the drawn balance. At 10–15% per annum, drawing $50,000 for one month costs roughly $417–$625 in interest.
Invoice finance is typically more expensive in absolute terms but scales with your revenue — and the limit grows as your invoice book grows.
Which Should You Choose?
Choose invoice finance if:
- You invoice other businesses and have payment terms of 30–90 days
- Your cash flow gaps are directly tied to slow-paying customers
- Your invoice book is growing and you want funding that scales with it
Choose a business overdraft if:
- Your cash flow gaps are irregular and unpredictable
- You deal mainly with retail customers (not invoiceable)
- You want simple access to funds without invoice-by-invoice administration
- Your overdraft needs are modest ($10,000–$100,000)
Can You Have Both?
Yes — and many businesses do. An overdraft provides a safety net for general cash flow, while invoice finance handles the larger, predictable gaps tied to specific invoices. A broker can help you structure both without over-leveraging.
