Shared considerations
- Both are working-capital facilities, not project finance for capex.
- Both can be withdrawn or repriced; review notice periods carefully.
- Personal guarantees are common on both, especially for newer businesses.
- Compare effective annual cost, not just the headline rate or fee.
Frequently asked questions
- Why are bank overdrafts harder to get than they used to be?
- UK high-street banks have tightened SME overdraft appetite since 2008 and again post-pandemic. Many newer or smaller businesses are offered card or term-loan products instead. This is a structural shift, not a comment on any individual business.
- Will my customers know I am using invoice finance?
- It depends on the product. Factoring is disclosed: the lender collects directly from your customers. Confidential invoice discounting keeps the arrangement private; you continue to collect, with the lender funding against the ledger in the background.
- Can I use both at the same time?
- Sometimes, but lenders will want to see how the facilities sit alongside each other, and one may take a charge that restricts the other. Disclose existing facilities up front to avoid offers being withdrawn at underwriting.
- Is invoice finance more expensive than an overdraft?
- Not always. Headline rates differ in structure, so compare the total annual cost on the same level of drawn funds. Invoice finance often funds far more than an overdraft would, which changes the picture for growing businesses.
