Where will the growth come from?

A growth case often starts with a simple ambition: increase revenue by 25%, double the business or enter a faster-growing segment. It is tempting to respond with a catalogue of ideas: raise prices, sell more, launch products, enter markets, acquire a competitor.

The harder and more useful task is to show which combination can deliver the target, by the deadline, at acceptable economics. A good growth strategy has arithmetic behind it and a reason to believe the business can execute it.

Start with the gap. Then build the plan.

Find out what has to grow, and by when

Revenue, profit, market share and customer count can move in different directions. Even “revenue growth” needs a defined period and starting point.

Suppose a workflow-software business has $200 million in year-end annual recurring revenue, or ARR. It wants to reach $250 million by the end of next year, a 25% increase.

ARR is the annualised recurring value of the business at a point in time. It is different from the revenue earned across the year. A contract beginning in December can make a substantial contribution to year-end ARR while generating only a small amount of that year's recognised revenue.

That distinction matters when comparing initiatives. Use the metric in the objective consistently, and check whether management also has a profit or cash constraint.

Separate the target from the base forecast

Assume management expects the current plan to produce 8% ARR growth. That would take the business from $200 million to $216 million. The additional growth strategy must therefore close a $34 million gap.

Do not accept the 8% simply because the business grew at that rate last year. Ask what supports it: renewals, customer losses, expansion in existing accounts, signed new contracts and the sales pipeline.

If the forecast already includes a planned price increase, you cannot add the same increase again as a new opportunity. If it assumes customer retention improves, identify the work and resources required to achieve that improvement.

A forecast is a set of operating assumptions. Making those assumptions visible prevents the growth plan from resting on an unexplained number.

Generate options from the way the business earns money

For the software company, the useful questions are concrete. Can more employees use the product within existing accounts? Will customers pay for a premium analytics module? Can a partner reach midmarket buyers the current sales team does not serve? Could a new geography support a repeatable sales motion?

A simple map helps keep the possibilities broad:

Growth routeWhat needs to be true
Retain more existing businessPreventable losses can be reduced at an acceptable cost
Sell more to current customersCustomers have a real additional need and budget
Win new customers with the current offerA reachable segment can be acquired profitably
Add a product or enter a marketThe company can build the capabilities and demand in time

Use this to generate and organise possibilities. Then narrow the work around the client's starting position and capabilities. An existing customer relationship helps only if it supports selling something those customers value.

Size incremental growth without counting it twice

Suppose the first estimates are:

InitiativePotential incremental year-end ARRImportant qualification
Enterprise upsell$12mIncludes some analytics spending
Premium analytics module$10m$4m duplicates the upsell estimate
Partner-led acquisition$12mCan launch within the year
New geography$15mMeaningful sales begin after next year

The two existing-customer initiatives contribute $18 million together: $12 million plus $10 million, less $4 million of duplicated revenue. Add $12 million from partner acquisition and the on-time portfolio contributes $30 million.

The result is $246 million ARR, leaving $4 million of the target unfilled.

Do not quietly round that up to a successful plan. Say that the current options support 23% growth, and explain what additional evidence or opportunity is needed to reach 25%.

The overlap deduction needs a commercial explanation. Here it removes the same analytics revenue counted under two initiatives. Merely selling two different products to the same customer would not, by itself, be double counting. Ask whether the same spend, contract or volume has entered the model twice.

How much added annual revenue can the plan credibly count by December?

Check whether the initiatives can happen together

A spreadsheet can add opportunities that the organisation cannot deliver simultaneously. The enterprise upsell and analytics launch may both require the same implementation team. The partner channel may depend on a product integration that is not yet built.

Translate each attractive initiative into its main requirements: people, product work, sales effort, launch spending and lead time. Then test the combined plan against the resources available.

A $12 million channel opportunity that requires 600 new customers at $20,000 ARR each has a useful operational implication. Can the partner source, close and onboard 600 customers before year-end? What conversion rate and sales cycle does that imply?

If only 300 can become live customers in time, the year's contribution falls to $6 million. That changes the portfolio decision even if the long-run opportunity remains attractive.

Our resource-allocation framework explains how to compare competing uses of a constrained team or budget.

Compare the economics behind the growth

The objective may be ARR, but management still needs to understand what buying that growth costs.

For a simplified comparison, suppose the partner's 600 new customers each produce $20,000 annual revenue and $12,000 annual contribution before acquisition spending. Acquisition costs $18,000 per customer. At a steady contribution rate, acquisition payback is 18 months.

That calculation assumes customers stay and the contribution arrives as expected. A channel with heavy early cancellations or substantial onboarding costs needs a different forecast. If management requires payback within a year, the proposal needs better economics or a deliberate exception to that constraint.

Keep the timelines distinct. Annualised contribution at year-end is not the cash earned during a staggered rollout. Growth can meet an ARR target while consuming more cash than the company can fund.

This is why I would present the amount, timing and economics together. Ranking opportunities solely by their largest revenue estimate hides the most consequential trade-offs.

Choose your answer

Recommend a portfolio and name the unresolved gap

A useful recommendation from the initial numbers would sound like this:

“Prioritise the existing-customer offer and partner acquisition, subject to validating demand and delivery capacity. Together they add $30 million ARR above the base and take us to $246 million. That leaves a $4 million gap, so the current plan does not yet support the full target. I would first test whether we can improve retention beyond the base forecast or expand the feasible partner opportunity. Geographic expansion may support later years, but it cannot close next year's gap.”

The answer is confident because it distinguishes what the plan delivers from what remains unresolved. It does not need an invented final lever to make the arithmetic look tidy.

If retention is the next question, use the churn framework to identify what is actually causing losses. To practise assessing a single growth route, try EdTech Paid Acquisition and explain how you would connect customer acquisition to the growth target and its economics.

Frequently asked questions

Defining the growth target

What should I clarify first in a growth strategy case?

Clarify exactly what has to grow and by when. Revenue, profit, market share and customer count can move in different directions, so each needs a different plan. Even a revenue target needs a defined period and starting point. Without them, you cannot tell whether an initiative contributes enough or arrives in time.

What is ARR and why does it matter in a software growth case?

Annual recurring revenue, or ARR, is the annualised recurring value of the business at a point in time. In the article's example, the business wants to move from $200 million to $250 million of year-end ARR by the end of next year. Because ARR is measured at year end, initiatives must start contributing before that date.

Why separate the base forecast from the growth target?

The new strategy only needs to close the gap the current plan leaves. If management expects 8% growth, ARR would reach $216 million without new initiatives. That leaves a $34 million gap to the $250 million target. Sizing initiatives against the full increase would overstate what the strategy has to deliver.

Can I assume last year's growth rate will continue?

No. Ask what supports the base forecast before you accept it. Look at renewals, customer losses, expansion in existing accounts and signed new contracts. A forecast built on these drivers is more reliable than a repeat of last year's rate. A weaker base would also widen the gap your strategy must close.

Generating and sizing options

How do I come up with growth ideas that go beyond a generic list?

Generate options from the way the business earns money. For a software company, ask concrete questions. Can more employees use the product within existing accounts? Will customers pay for a premium analytics module? Can a partner reach buyers the sales team does not serve? Could a new geography support a repeatable sales motion?

What's wrong with listing price rises, new products, new markets and acquisitions?

A catalogue of ideas does not show which combination can deliver the target by the deadline at acceptable economics. Interviewers want arithmetic behind the plan and a reason to believe each option applies to this business. Linking options to how the client earns money keeps the list broad and still relevant.

How do I avoid double counting when I add up growth initiatives?

Check whether estimates overlap before you total them. In the example, the $12 million enterprise upsell already includes some analytics spending. Of the $10 million estimated for the premium analytics module, $4 million duplicates the upsell estimate. Together they contribute $18 million, not $22 million.

Does a large potential number mean an initiative should be prioritised?

Not on its own. Read each estimate alongside its qualification. The partner-led acquisition estimate matters partly because the partner channel can launch within the year, which a year-end ARR target requires. An overlap, a long lead time or an unproven assumption can make a larger figure less useful than it first appears.

Testing feasibility and economics

Can all the growth initiatives run at the same time?

Not necessarily, so test them together. The upsell and analytics launch may both need the same implementation team. The partner channel may depend on a product integration that is not yet built. Translate each initiative into people, product work, sales effort, launch spending and lead time, then check the combined plan against available resources.

If the target is ARR, why do I need to look at costs?

Management needs to understand what buying the growth costs. In the simplified partner example, each new customer produces $12,000 of annual contribution before acquisition spending. Acquiring each one costs $18,000. At a steady contribution rate, acquisition payback is 18 months. That is useful context even though the target is ARR.

What assumptions sit behind an acquisition payback calculation?

The calculation assumes customers stay and the contribution arrives as expected. If customers leave early or contribution takes longer to build, the cost of acquiring them takes longer to recover. Stating these assumptions shows the interviewer that you know the payback figure depends on retention and contribution holding up.

Making the recommendation

What should I say if my plan doesn't fully reach the target?

Say so plainly and name the gap. In the example, the existing-customer offer and partner acquisition add $30 million above the base. That reaches $246 million and leaves $4 million short of the target. Stating that the plan does not yet support the full target is more credible than stretching estimates to make the numbers close.

How should I phrase a growth strategy recommendation?

Name the initiatives to prioritise and the conditions attached. Then give the total they deliver and what remains unresolved. For example, prioritise the existing-customer offer and partner acquisition, subject to validating demand and delivery capacity. Then quantify where that leaves the business against the target and say what you would test first.
