How Would Your Business Respond to a 20% Fall in Revenue?

Most businesses have a growth plan. Fewer have given the same level of thought to what they’d actually do if revenue fell sharply. It’s an understandable gap: nobody enjoys planning for a downturn that hasn’t happened. But that’s exactly why it’s worth doing while things are calm rather than when they’re not. Here are five questions worth working through now, so the answers are ready if you ever need them.

Why should I test for a scenario I’m not expecting?

The purpose of this kind of planning isn’t to predict a downturn or assume one is coming. It’s to understand your options before you need them. A business that has already thought through how it would respond to a revenue shock tends to make calmer, better-informed decisions if conditions do change, simply because the thinking has already been done. A business that hasn’t is left working it out under pressure, often with less time and fewer choices than it would like.

Think of it less as a worst-case exercise and more as a stress test: a way of checking that the business is resilient, and identifying where it isn’t, while you still have the luxury of time to act.

Which costs can be reduced quickly without damaging the business?

Not all costs are equal when conditions tighten. Some can be reduced quickly with minimal impact; others are structural, contractual or core to how you deliver for clients, and cutting them carelessly can do more harm than the downturn itself. It’s worth mapping your cost base into rough categories before you need to:

• Discretionary costs that could be paused or reduced quickly, such as non-essential spending or one-off projects
• Variable costs that scale naturally with activity, such as casual labour or certain supplier arrangements
• Fixed and contractual costs that are harder to move, such as leases, core staffing and long-term agreements

Knowing which category each cost sits in means that if you ever need to act, you’re making deliberate choices rather than cutting whatever’s easiest to find.

How long would my cash and funding last?

This is often the most revealing question of the five, and the one businesses are least likely to have modelled precisely. If revenue fell by 20% and stayed there for a period, how long would your current cash reserves and funding facilities comfortably cover the business? A rough sense isn’t the same as a modelled answer, and the gap between the two is usually where the surprises live.

It’s also worth checking what capacity you already have. Undrawn facilities, asset finance options or lending relationships are far easier to arrange, and on better terms, when your business is performing normally than when a lender can see you’re under pressure.

Where does concentration risk sit in my revenue?

A 20% fall in revenue rarely happens evenly across the business. It’s far more likely to come from the loss, or reduction, of a small number of customers, suppliers or revenue streams that carry more weight than you’d ideally want them to. Worth reviewing:

• What proportion of revenue comes from your largest handful of customers
• Whether any single supplier or input creates a dependency that would be hard to replace quickly
• Whether one product, service line or market accounts for a disproportionate share of profitability

Concentration risk isn’t necessarily a problem to fix immediately, but it is something you want to know about in advance, rather than discover when one of those relationships changes.

What early warning signs would I actually see?

By the time a 20% revenue fall shows up in your financial statements, it’s already well underway. The businesses that respond earliest are usually the ones watching a small set of leading indicators that move before the headline numbers do. These might include:

• Changes in sales pipeline, enquiry volumes or order backlogs
• Shifts in customer payment behaviour or days outstanding
• Movement in key input costs or supplier lead times
• Early signals within a specific customer or industry segment you’re exposed to

Agreeing in advance what you’d actually watch, and who’s responsible for watching it, turns this from a vague sense of unease into something genuinely useful.

Which decisions are better made now than under pressure?

Some decisions are far easier to make calmly, in advance, than reactively, under pressure. These might include which costs you’d cut first and in what order, how you’d communicate with staff, customers or lenders if conditions changed, or which growth plans you’d pause versus protect. Agreeing on these in principle now doesn’t commit you to anything. It simply means that if conditions do shift, you’re executing a plan rather than debating one for the first time while the pressure is already on.

Preparation gives you options, not predictions

None of this is about expecting the worst. It’s about making sure that if conditions do change, you’re the one making the decisions, on your terms and with time on your side, rather than reacting to events after the fact. Businesses that have already done this thinking tend to move faster, make better calls and protect more of what they’ve built when it matters most.
