When I set out to build a multi-million-pound online business, the budget was just £2,000 and the “warehouse” was a corner of the kitchen. Today the company turns over several million pounds a year. We have made plenty of mistakes along the way, but we have also developed a set of principles that continue to guide us.

Here are the seven lessons that have mattered most as we have grown.

1. Put customer service at the centre of everything

If there is one factor that has underpinned our growth, it is this. Customers remember how you treat them when something goes wrong, and they tell other people. We have seen frustrated buyers become loyal advocates after we resolved a problem quickly and fairly.

Tips

• Dispatch orders as fast as you can. We aim to dispatch every item ordered before midday on the same day, and we often beat that. Customers are delighted when they order on a Friday afternoon and receive their parcel on Saturday morning.
• Fix mistakes without argument. Apologise, replace or refund promptly, and if the error was yours, send a small goodwill gesture. The cost is usually far less than the value of a lost customer.
• Exceed the minimum legal standard. UK consumer rights under the Consumer Rights Act 2015 are the baseline. For online sales, that includes a 14-day cooling-off period for most goods. Aim higher by being generous with returns and responsive to queries.

2. Keep overheads low, but never cut product quality

A bank manager friend once told me that he can spot a failing business by the moment it signs the lease on a flagship office. Until we reached a million pounds in turnover, I ran the business from home. A stable became a stock room and a portacabin went in the yard. When we finally outgrew the house, we moved into a cheap unit on an industrial estate rather than a flashy building.

The two areas where we have always been willing to spend are the product and our people.

A supplier once told us they could hit any price we wanted, but the quality would suffer. We chose to pay more for properly compliant goods. That decision paid off when Trading Standards inspected one of our resellers and removed a competitor’s products from the shelves while ours passed every check.

Tips

• Work from home or shared premises for as long as possible. Many women-led businesses start this way. See the latest figures on women in business in the UK.
• Negotiate hard on rent, utilities and software, not on safety or materials.
• Keep product compliance records up to date. For most goods placed on the GB market, CE marking remains valid under current government rules, although UKCA marking is also accepted. Check the latest guidance on gov.uk for your product category.

3. Reward your staff properly

As you grow, you depend on your team to deliver the customer experience that wins repeat business. You cannot expect that level of care if people do not feel valued.

Tips

• Pay at least the real Living Wage. The Living Wage Foundation sets independently calculated hourly rates that reflect the actual cost of living. Displaying the Living Wage logo on job adverts signals that you value your team. For context, the statutory National Living Wage is set to rise to £12.21 per hour from April 2026 for workers aged 21 and over, following the government’s 2024 announcement.
• Use bonuses to share success. Bonuses link pay to performance without locking the business into unsustainable fixed costs.
• Give real responsibility. Delegation frees you up and shows staff you trust them. Match roles to strengths, and if someone is promoted beyond their ability, find a role where they can excel.
• Say thank you. Recognition can matter as much as money. Two team members recently told me this was the best job they had ever had. That is almost as rewarding as the profit. Almost.

4. Hire with care

People are the most important part of the business, so recruitment deserves time and rigour. We once offered a role to a candidate who failed to appear on day one and then sent abusive emails. It was a stark reminder that a bad hire is far more expensive than a delayed hire.

Tips

• Hold several interviews and include a practical task where possible.
• Never hire because you are desperate to fill a chair.
• Advertise where your ideal candidates actually look. Specialist job boards, industry networks and word-of-mouth often produce better matches than generic channels.
• Always check references by phone. Ask former employers whether they would rehire the person tomorrow. Tone of voice tells you a lot.

5. Target growth markets and blend experience with new skills

We are a family business, and that has given us a useful mix of perspectives. Decades of trading experience help us know when to walk away from a bad deal and how to manage cash flow. Younger team members keep us current on digital marketing, social media and compliance technology.

Tips

• Look for markets that are growing and where you can add genuine value.
• Pair seasoned judgement with people who understand the latest platforms and tools. AI adoption is now a practical necessity for many online retailers, from inventory forecasting to customer service chatbots.
• Make sure someone in the business owns compliance, data protection and terms and conditions as you scale.

6. Test marketing channels and measure the return

We have tried magazine adverts and found the return disappointing. Our most effective marketing has been content: useful blog posts, PR and email. One article was shared tens of thousands of times and cost little more than the time to write it.

That does not mean every business should abandon traditional marketing. It means you should test, measure and double down on what works for your audience.

Tips

• Track everything. Use unique discount codes, UTM links and Google Analytics 4 to see which channels bring sales.
• Invest in content and SEO. A helpful blog post or guide can attract customers for years.
• Build an email list. Email remains one of the highest-return channels for UK online retailers.
• Keep your website fast, mobile-friendly and easy to navigate. Poor user experience wastes every pound you spend on advertising.

7. Build genuine relationships with customers

One advantage a smaller business has over a corporate giant is personality. Customers talk to real people, not a call centre script.

Many of our regulars ask for team members by name. We have received thank-you cards, gifts and dozens of unsolicited testimonials. That kind of loyalty is hard to buy.

Tips

• Communicate regularly but respectfully. Share promotions, but also useful tips, product guides and behind-the-scenes updates.
• Talk with customers, not at them. Reply to comments and emails personally.
• Put faces to names. Photos of the team on your website and social media help customers feel connected.
• Listen and act. If customers keep asking for the same thing, consider offering it.
• Show personality. A little humour on social media can build rapport that has nothing to do with your product and everything to do with trust.
