1. Check Whether Your Business Idea Is Viable

Before registering a company or signing a property lease, confirm that there is sufficient demand for your idea.

Define exactly:

  • What you will sell
  • Who will buy it
  • Why customers should choose you
  • What they currently use instead
  • How much they are willing to pay
  • How often they are likely to purchase

Speak directly with potential customers rather than relying only on opinions from friends and family. Review nearby competitors, online reviews, local footfall, pricing and service gaps.

Someone planning a takeaway should research more than the popularity of the cuisine. They should also examine local delivery coverage, competitor menu prices, average delivery times, parking, kitchen capacity, staffing requirements and demand at different times of day.

A promising idea still needs to work financially. Selling large volumes will not create a sustainable business if ingredient, labour, rent, energy, delivery and payment costs leave little profit.

2. Write a Practical Business Plan

A business plan explains how the business will attract customers, generate revenue and cover its costs. It can also support applications for finance or investment. GOV.UK recommends preparing a business plan and points new businesses towards cash-flow forecast templates and other planning resources. uld cover:

Business overview

Explain what the business offers, where it will operate and what problem it solves.

Target market

Describe your ideal customer by location, needs, spending habits and buying behaviour.

Competitor analysis

Identify direct and indirect competitors. Compare their prices, reviews, product range, opening hours, payment options and customer experience.

Sales and marketing plan

Explain how customers will discover the business. This might include local search, social media, leaflets, partnerships, email marketing, delivery platforms or passing footfall.

Operational plan

List the premises, equipment, suppliers, staff, software, payment systems and licences needed to trade.

Financial forecast

Estimate sales, gross profit, overheads, tax, loan repayments and monthly cash flow. Include a realistic scenario and a more cautious scenario.

3. Calculate Your Start-Up Costs

Many new businesses underestimate how much cash they need before opening and during the first few months.

Common start-up costs include:

Cost category Examples
Premises Deposit, advance rent, legal fees and fit-out
Equipment EPOS hardware, refrigeration, shelving, kitchen equipment or displays
Initial stock Products, ingredients, packaging and consumables
Professional costs Accountant, solicitor, licences and registrations
Technology Website, broadband, EPOS software and card machine
Staffing Recruitment, training, uniforms, payroll and pension costs
Marketing Signage, photography, local advertising and launch promotions
Working capital Rent, wages, stock replenishment and bills before sales stabilise

Separate one-off costs from monthly operating expenses. You should also calculate your break-even point: the level of sales required to cover all fixed and variable costs.

For example, a grocery shop may need to budget not only for shelves and opening stock but also for refrigeration, barcode scanning, card processing, security, waste, price changes and ongoing stock replenishment.

The most common structures for a small business in the UK are sole trader, limited company and business partnership.

Structure Main advantages Main considerations
Sole trader Simple setup and fewer administrative requirements You are personally responsible for business debts
Limited company The company is legally separate from its owners More reporting, accounting and director responsibilities
Partnership Suitable when two or more people run a business together Partners need a clear agreement covering responsibilities and profit sharing

A sole trader has unlimited liability, meaning the owner is personally responsible for business debts. A limited company is legally separate from its owners and must file company accounts and tax information. cture depends on your risk, income, funding plans and personal circumstances. Consider speaking with an accountant before deciding.

5. Register Your Business and Taxes

Registering as a sole trader

You can begin trading as a sole trader without first incorporating a company. However, you generally need to register for Self Assessment when your gross trading income exceeds £1,000 during a tax year, which runs from 6 April to 5 April. You must also keep adequate business records. ng a limited company

A limited company must be registered with Companies House before it starts trading.

As of July 2026, online company incorporation costs £100 and is usually completed within 24 hours. You will need information including the company name, registered office address, directors, shareholders and people with significant control. Identity verification may also be required. nies must manage Corporation Tax, annual accounts, confirmation statements and other filing responsibilities. ng for VAT

Businesses generally have to register for VAT when their taxable turnover for the previous 12 months exceeds £90,000, or when they expect to exceed £90,000 within the next 30 days.

A business can also register voluntarily below the threshold, although this should be considered carefully with an accountant. should also check whether the Making Tax Digital for Income Tax rules apply to them, as the phased rollout began on 6 April 2026 for people meeting the relevant qualifying-income criteria. icences, Premises and Insurance

The permissions you need depend on your industry, location and activities. The GOV.UK licence finder covers hundreds of licences, permits and certifications, while local councils manage many activity-specific permissions. re permission to:

  • Sell alcohol
  • Prepare or sell food
  • Trade on a street or market
  • Play recorded music
  • Provide late-night refreshments
  • Display external signage
  • Place tables or chairs on a pavement
  • Operate gaming machines
  • Provide certain regulated services

Food business registration

Restaurants, cafés, takeaways, grocery shops, mobile food businesses and other food operators normally need to register with their local authority at least 28 days before starting to trade. Registration is free and cannot normally be refused. premises

Most shops, pubs, offices and other non-domestic properties may be subject to business rates. Rules and relief schemes can vary between England, Scotland, Wales and Northern Ireland, so check the requirements for your location. insurance

Consider public liability, product liability, stock, contents, interruption, cyber and professional indemnity cover according to your risks.

Once you become an employer, you will normally need Employers’ Liability insurance from an authorised insurer, with cover of at least £5 million. Banking and Bookkeeping

Create a clear separation between personal and business transactions. A dedicated business account makes it easier to track sales, pay suppliers, reconcile card settlements and prepare tax returns.

Set up bookkeeping from your first transaction. Record:

  • Sales
  • Purchases
  • Operating expenses
  • Supplier invoices
  • Payroll
  • VAT, where applicable
  • Cash takings
  • Card settlements
  • Refunds
  • Stock adjustments

Do not wait until the end of the tax year to organise your records. Regular bookkeeping makes it easier to identify cash shortages, unpaid invoices, excessive spending and declining margins.

8. Choose Your EPOS and Payment Systems

Retail and hospitality businesses should choose their operational technology before opening rather than adding disconnected systems later.

A modern EPOS system can bring together checkout, product information, stock control, sales reports, staff access, discounts and customer records.

For retail businesses, Switch & Save provides an AI-powered retail EPOS system designed for shops, supermarkets, convenience stores and other retailers.

Restaurants, takeaways, cafés and bars can explore a dedicated hospitality EPOS system with tools for ordering, table management, kitchen communication and reporting.

When comparing card machines for UK businesses, consider:

  • Transaction rates
  • Monthly charges
  • Contract length
  • Settlement times
  • Minimum monthly fees
  • Refund charges
  • Mobile wallet acceptance
  • EPOS integration
  • Technical support
  • Costs for additional terminals

The cheapest advertised transaction rate is not always the lowest total-cost option. Compare the complete agreement based on your expected card turnover and average transaction value.

9. Arrange Business Funding

Your funding requirement should come from your business plan and cash-flow forecast rather than an approximate figure.

Possible funding sources include:

  • Personal savings
  • Family investment
  • Bank lending
  • Start-up loans
  • Asset finance
  • Overdrafts
  • Investor funding
  • Business finance linked to trading performance

Keep a cash reserve for delays, unexpected repairs, seasonal sales changes and higher-than-expected costs.

New businesses considering external funding should review the Switch & Save guide to business finance for UK start-ups. Finance remains subject to eligibility, affordability checks and provider terms.

10. Launch, Market and Measure Your Business

A successful launch is not simply an opening-day promotion. It should create awareness, collect customer feedback and establish repeatable marketing channels.

Before opening:

  1. Create your website and local business listings.
  2. Make opening hours, location and contact details easy to find.
  3. Test your EPOS, printers, card machines and broadband.
  4. Train employees on payments, refunds, stock and customer service.
  5. Test suppliers and delivery schedules.
  6. Run a controlled soft launch where possible.
  7. Prepare launch offers without damaging your margins.

After opening, monitor a small group of useful metrics:

  • Daily and weekly sales
  • Gross profit
  • Average transaction value
  • Best- and worst-selling products
  • Labour cost
  • Stock loss and waste
  • Refunds and discounts
  • Cash and card differences
  • Repeat customer activity
  • Available cash

An EPOS reporting dashboard can make these figures easier to review without relying on handwritten records or separate spreadsheets.
