Match the tool to the gap

A short, temporary cash-flow gap — a late customer, a timing mismatch, a seasonal dip — is best funded with something you pay for only while you use it. A revolving facility or an overdraft charges interest only on what you draw for the days you draw it, so a brief gap costs little. A fixed term loan, by contrast, saddles you with a standing debt long after the gap has closed.

Why fixed borrowing overshoots

Taking a term loan to cover a two-week gap means paying interest for the whole term on money you needed for a fortnight. It is the wrong shape of finance for the need. The cheapest option for a genuinely short, one-off gap is the most flexible one, drawn minimally and repaid the moment the incoming cash lands — see drawdown timing. On daily-interest facilities this is especially efficient.

Fixing recurring gaps

If the same gap keeps opening, funding it repeatedly — however cheaply — treats the symptom. A recurring gap usually points to slow-paying customers or a timing mismatch worth fixing at source: tighter credit control, invoice finance to pull cash forward, or a better-timed cash cycle. Fund the one-off gap flexibly; fix the recurring one structurally.

Compare a facility against a loan for your gap on the true cost calculator, and for a flexible line, explore a revolving facility.

Frequently asked questions

Is an overdraft or a loan cheaper for a short gap?

For a short, one-off gap, an overdraft or revolving facility is usually cheaper, because you pay interest only on what you draw for the days you draw it — a brief dip costs little. A term loan burdens you with a standing debt and interest for its whole term, long after a short gap has closed. Match flexible finance to short gaps and reserve term loans for steady, longer-term needs.

What if the same cash-flow gap keeps happening?

Then fund the one-off gap flexibly but fix the recurring cause at source, because repeatedly funding it only treats the symptom. A persistent gap usually reflects slow-paying customers or a timing mismatch — address it with tighter credit control, invoice finance to bring cash forward, or a better-timed cash cycle. Structural fixes are cheaper over time than borrowing to cover the same gap again and again.
