How Do I Know What Else My Business Could Sell?

The question 'what else could we sell?' is common for owners who feel their current growth has plateaued. It is often driven by a desire to leverage existing relationships or a suspicion that the company is missing out on revenue it is well-placed to capture.

However, simply adding new products or services to the portfolio can be a major source of complexity and margin erosion. The key to identifying genuine opportunities lies in aligning what your business is uniquely good at doing with what your customers are actually asking for—or would be willing to pay for if the value was clear.

The fallacy of diversification

Many business leaders believe that diversification is a safety net. In reality, poorly planned diversification is often the fastest way to dilute a company’s resources and destroy its core competitive advantage. The 'what else could we sell' question should only be answered after a rigorous internal and external audit.

When you add a new revenue stream, you aren't just adding a line to the P&L. You are adding to the complexity of your operations, the cognitive load of your sales team, and the potential for confusion in your brand identity. Therefore, the first step is always to look for 'high-synergy' opportunities—those that require minimal new infrastructure but offer significant new value to your existing customer base.

1. Assessing your existing assets

Before looking at new markets, look at the assets you already own that are currently under-monetised. These are the low-hanging fruit of channel creation.

Unused capacity

Does your workshop sit empty on Fridays? Does your delivery fleet return half-empty? Does your software team have periods between major releases where they are under-utilised? This spare capacity is a cost you are already paying. Finding a way to sell this capacity to a different customer segment—perhaps a B2C audience if you are B2B, or a non-competing partner—is 'pure' revenue that drops straight to the bottom line.

Intellectual property and data

Often, the way you run your business is as valuable as what the business actually does. If you have developed a proprietary software tool for your own warehouse management, or a unique training methodology for your sales team, there may be a market for that tool or training. This is 'capability-led' revenue.

Customer access and trust

If you have 500 loyal B2B customers who trust your advice on engineering, they are likely buying related services—like maintenance, insurance, or training—from someone else. You have already paid the 'cost of acquisition' for these customers. Selling them something else is a high-margin opportunity because the marketing cost is near zero.

2. The commercial reasoning: Six key filters

Every potential new revenue stream must pass through a commercial 'gauntlet'. If it fails more than two of these, it is likely a distraction, not a growth strategy.

• Revenue: Is the addressable market for this new offering large enough to move the needle on your total growth? A new stream that adds 1% to revenue but takes 20% of management time is a net loss.
• Margin: Will this stream be higher or lower margin than your core business? Low-margin 'add-ons' can often cannibalise higher-margin sales if the sales team finds them easier to pitch.
• Cash: What is the cash-flow cycle? Service businesses adding products often find their cash trapped in inventory. B2B businesses moving to D2C may see faster cash, but higher transaction costs.
• Capacity: Do you have the physical space, the people, and the tools to deliver this now? If you have to hire and build before you sell, you are starting a new business, not adding a stream.
• Complexity: How many new processes does this require? New billing cycles, new shipping methods, and new warranty support all add 'hidden' costs that erode profit.
• Risk: Does this new stream compete with your existing partners? If you start selling a component that your best distributor also sells, you may lose the distributor and the channel entirely.

3. Identifying adjacent market gaps

The most successful new revenue streams are 'adjacencies'. These are services or products that are a natural next step for your current customers. For example, a commercial office furniture manufacturer (B2B) might start offering office design and fit-out services. The customer was going to buy the furniture anyway; by adding the service, the manufacturer captures more of the project value and increases their 'stickiness'.

To identify these, look at what your customers do *immediately before* and *immediately after* they use your service. Can you solve those problems for them too?

4. Validate before you build

One of the most expensive mistakes in business is building a product that no one wants. In Channel Creation, validation should precede investment. This means:

• Customer interviews: Ask your top 10 customers about the specific pain point you intend to solve. Do not ask 'would you buy this?'. Ask 'what are you currently doing to solve this, and what do you pay for that solution?'
• The 'Manual' Pilot: Before automating a new service or building a new product feature, deliver it manually. If you can't sell and deliver it by hand to five customers, a fancy system won't save it.
• The 30-day trial: Launch the offering to a small, controlled group for a limited time. Use the Growth Route Finder at Evans Sales Consultancy to map how this new route fits into your wider strategy before committing long-term resources.

When NOT to do this

There are times when the best answer to 'what else could we sell?' is 'nothing yet'. You should avoid adding new revenue streams if:

• Your core service delivery is inconsistent or failing. Diversification is not a cure for poor operations.
• Your sales team is already at full capacity and struggling to hit targets for the core product.
• The new stream requires a fundamentally different brand promise that would confuse your existing customers.
• The upfront capital required would put your core business's cash reserves at risk.

Conclusion

Knowing what else your business could sell is a process of systematic discovery, not a sudden flash of inspiration. By leveraging your existing assets, focusing on high-margin adjacencies, and rigorously testing demand before investing, you can build a more resilient and profitable business. But remember: the goal of growth is not just a larger number at the bottom of the invoice—it is a better, more sustainable commercial operation.
