Most directors who reach for short-term business finance reach for one of two things: a short-term business loan, or a business overdraft from their existing bank. Both products promise to fill a cashflow gap. Both are widely advertised. But they’re built around different mechanics and they genuinely suit different shapes of need. This article is the side-by-side comparison.
The mechanics
A short-term business loan is a defined lump sum, drawn on a single day, repaid in scheduled instalments over a fixed term. You know the start, the end, the total cost, and each individual repayment up front. The cost is fixed — borrow £300 for 30 days at the agreed rate and the cost is the same whether or not your cashflow improves halfway through.
A business overdraft is a credit limit on your business current account. You can take the account balance below £0 up to the limit, at any time. Interest accrues daily on the negative balance. The cost is variable — pay back faster, pay less interest.
Where the short-term loan wins
- A specific named purchase. If you know you need £4,000 for a piece of equipment on Friday, a short-term loan is the right tool. You know what you’re borrowing for, you know exactly what it’ll cost, you know exactly when you’ll have repaid it.
- Predictability for budgeting. A fixed schedule is easier to plan around than an open-ended overdraft balance.
- Faster to arrange. A short-term business loan from a fintech lender typically goes from application to funds in 24-48 hours; a new business overdraft from a high-street bank typically takes 2-6 weeks.
- Not subject to bank withdrawal. A formal short-term loan can’t be “called in” mid-term the way an on-demand overdraft can.
Where the overdraft wins
- Genuinely uncertain need. If you don’t know whether you’ll need £500 or £5,000, an overdraft sized at £5,000 gives you the optionality and you only pay for what you actually use.
- Lower headline rate. A high-street bank business overdraft is typically cheaper in % terms than a fintech short-term loan — though faster setup and other features sometimes outweigh that.
- Integrated with your bank account. No separate platform to manage; the overdraft just sits there as part of your existing account.
Where the comparison gets blurry — Credicorp Flex
Credicorp’s revolving credit facility (Flex) sits in between. It has the “pay only for what you actually draw” flexibility of an overdraft, combined with the fast-arrange + can-not-be-called-back security of a short-term loan. The headline rate is higher than a bank overdraft, but the per-drawing cap keeps worst-case cost predictable, and the setup time is hours, not weeks. There’s a fuller three-way comparison here.
How to choose
Three questions:
- Do you know the exact amount and the exact deadline? Yes → short-term loan. No → overdraft or Flex.
- How fast do you need the facility in place? This week → fintech short-term loan or Flex. In a month → bank overdraft.
- Are you confident your bank won’t withdraw the facility at the wrong moment? Yes → bank overdraft is fine. No → fintech short-term loan or Flex avoids that risk.
