Growth systems practice
ABP connects marketing investment, operating capacity and commercial evidence so growth decisions can be measured as a system rather than a collection of activities.

A short video from FRED'S TECH HUB makes a useful argument: understand five numbers before starting a business — return on investment, cash flow, customer acquisition cost, customer lifetime value, break-even point and the cost of your own time.
The list is simple. Using it properly is not. Each number answers a different question, and none should be treated as a promise that a business will succeed.
For an established business considering its next marketing, automation or AI investment, the same framework becomes a practical test: are we building an economic system, or adding activity that looks like growth?
1. ROI — define the return before the spend
Return on investment compares what an initiative produces with what it costs. The difficult part is not the formula. It is deciding what counts as a return, which costs belong in the denominator and how long the initiative gets to work.
A marketing system can create qualified demand, shorten a sales cycle or reduce manual labour. Those are different returns and they need different evidence. If the expected outcome cannot be named before approval, almost any result can be made to look successful afterwards.
- Name the commercial outcome before approving the investment.
- Include implementation, people, media, software and ongoing operating costs.
- Set the measurement window and the evidence required to continue, change or stop.
Five checks required before scaling
- Return is defined100%
- Cash timing is visible100%
- CAC and LTV use honest inputs100%
- Break-even volume is achievable100%
- Delivery time can scale100%
2. Cash flow — timing can defeat profit
Profit records whether revenue exceeds expenses over a period. Cash flow records when money actually enters and leaves the business. A profitable project can still create pressure when suppliers, salaries and advertising are paid well before customers pay you.
Growth therefore needs a funding rhythm, not only a revenue target. Deposits, billing terms, implementation stages and collection discipline determine how much growth the business can safely carry at once.
3. CAC and LTV — test the economics of a customer
Customer acquisition cost is the total sales and marketing cost required to win a new customer. Customer lifetime value estimates the gross value that customer contributes across the relationship. Put together, they test whether winning more customers strengthens the business or quietly erodes it.
The comparison is only useful when both sides are honest. CAC should include the people, tools and sales effort behind acquisition, not just advertising. LTV should be grounded in observed retention and margin where possible, not an optimistic forecast of future revenue.
- CAC = acquisition-related sales and marketing cost ÷ new customers won.
- LTV should reflect contribution after the direct cost of serving the customer.
- Read the ratio with payback time: value received years later cannot fund today's obligations.
4. Break-even — know the volume the model demands
Break-even is the point at which contribution from sales covers fixed costs. It turns a broad ambition into an operating requirement: how many sales, subscriptions or retained clients are needed before the model supports itself?
The answer should change decisions. If the required volume exceeds the market, the team's delivery capacity or the available acquisition budget, the model needs redesign before it needs more promotion.
5. The cost of time — separate leverage from workload
Founder and team time is often excluded because no invoice arrives for it. That makes labour-intensive offers look more profitable than they are and hides the point at which growth becomes operationally impossible.
The practical question is not whether people should work hard. It is whether each new customer requires the same amount of scarce senior attention. Standardised delivery, automation, reusable intellectual property and clear decision rights can increase capacity without reducing care.
Put the five numbers into one operating view
These measures are most useful together. ROI without cash timing can approve an unaffordable project. LTV without acquisition cost can celebrate unprofitable growth. Break-even without the cost of time can describe a business the team cannot physically deliver.
A sound growth decision connects the sequence: invest, acquire, deliver, collect, retain and learn. The result is not a perfect forecast. It is a visible set of assumptions that can be tested against reality before more capital and effort are committed.
Frequently asked
Short Answers.
- What numbers should I know before starting or scaling a business?
- Start with expected return on investment, cash-flow timing, customer acquisition cost, customer lifetime value, break-even volume and the cost of the team's time. Read them together rather than treating any one number as proof of viability.
- Is revenue growth enough to show that marketing is working?
- No. Revenue can grow while acquisition costs, delivery effort or slow payment terms weaken the business. Marketing performance should be read alongside margin, cash timing, retention and capacity.
- How should a business use CAC and LTV?
- Use fully loaded acquisition costs and evidence-based customer value, then examine how long it takes to recover the acquisition spend. The ratio is a decision aid, not a universal guarantee.
