100 Small Business Ideas to Start in 2027

The useful question is not which small business ideas to start in 2027 sound exciting — it is which ones you can actually reach a paying customer in, and what it will cost you to run. So this list of 100 is organised around that second question. Every idea below sits in one of four tiers based on how much software it needs: businesses that run on off-the-shelf tools, ones needing light custom work, ones needing real custom software, and ones where the software is the product.

The clusters are grounded in published government projections rather than guesswork. Where an area is genuinely growing — care services, energy retrofits, security work — that comes from Bureau of Labor Statistics data, cited inline. Where it is our own judgement about build cost and difficulty, we say so.

We build the software these businesses run on, which shapes the angle in one specific way: we have watched founders pick an idea in tier four while budgeting for tier one. That mismatch, far more than the idea itself, is what usually sinks the first year.

How to read this list

Two questions kill more small businesses than bad ideas do. Ask both before you fall in love with anything below.

What does customer number one actually cost?

Not customer one thousand — customer one. If the honest answer is "I don't know," the idea is unproven regardless of how large the market is. The best ideas on this list are ones where you can name three specific people who would plausibly pay you this month. Market size is a late-stage concern; access to the first buyer is the immediate one.

This is also why the boring ideas beat the interesting ones so often. A drainage contractor knows exactly who to call. A "platform connecting X to Y" does not, and needs both sides before either is useful.

What software does it actually need?

Here is where we can be more useful than a generic ideas list. Nearly every business needs to take bookings, take payments, and keep records. The question is whether generic tools cover it, or whether the thing that makes your business better than the incumbent is the software.

Tier	What you run it on	Typical monthly software cost	Build cost	When you outgrow it
1 — Off-the-shelf	Booking tool, payments, accounting, a simple site	Low — tens of pounds/dollars	None beyond a website	When manual admin per job exceeds the margin
2 — Light custom	Off-the-shelf plus a custom portal, calculator or integration	Low, plus a one-off build	Small project	When the custom piece becomes the main workflow
3 — Real custom	A proper internal system your delivery depends on	Moderate, plus hosting	Substantial project	When you want to sell the system itself
4 — Software is the product	The product, plus everything a SaaS needs around it	Ongoing engineering	Fund it as a product company	You never outgrow it — it is the business

Payments are the one cost you can pin down exactly at any tier. Stripe's published pricing is 2.9% + 30¢ per successful online transaction for domestic cards, or 2.7% + 5¢ in person, with international cards adding 1.5% and currency conversion 1%. Build that into your margin from day one — on thin-margin resale businesses it is the difference between viable and not.

What the data says is growing into 2027

Where the projections point

The BLS Employment Projections for 2024–2034 are the most credible public signal available about which sectors are expanding, and they are unambiguous in three places.

Care is the largest opportunity by volume. Healthcare and social assistance is projected to grow fastest of all 20 sectors at 8.4% and to add roughly 2.0 million jobs. Within it, services for the elderly and persons with disabilities is projected to grow 21.0% and add 528,500 jobs — more than any other detailed industry.

Energy is the largest opportunity by rate. Per BLS, solar electric power generation is projected to grow 180.2% and wind 81.4%. On the occupational side, wind turbine service technicians are projected to grow 49.9% and solar photovoltaic installers 42.1%.

Security and data are the fastest-growing technical work. Information security analysts are projected to grow 28.5%, the fastest-growing computer occupation, with data scientists at 33.5% and software publishers as an industry at 19.3%.

How many other people are trying

Optimism about a sector is not an edge if everyone shares it. The Census Bureau's Business Formation Statistics released on 12 August 2026 recorded 578,926 US business applications in July 2026, seasonally adjusted — up 8.1% on June, with 151,857 classified as high-propensity (those most likely to become employers).

Tier 1: ideas that run on off-the-shelf tools (1–30)

These need a website, a booking or quoting tool, payments and accounting. No custom software. They are the fastest to start and the ones where execution, not technology, decides the winner.

Care, health and ageing services (1–10)

The BLS numbers above make this the highest-volume opportunity on the list. Note that several of these are regulated and require licensing or background checks — that barrier is also your protection from competitors.

1. Non-medical home care — companionship, meals, light housekeeping for older adults.
2. Dementia-specific respite care giving family carers scheduled breaks.
3. Post-surgery recovery companion service for the first fortnight home.
4. Home safety modification — grab rails, ramps, lighting, fall prevention.
5. Medication management and reminder support.
6. Mobile foot care and routine nail services for limited-mobility clients.
7. Senior technology tutoring — video calls, online banking, telehealth logins.
8. Family caregiver coaching and care-system navigation.
9. Non-emergency medical transport to appointments.
10. Adult day programmes and social clubs for isolated older people.

Home services and skilled trades (11–20)

Unglamorous, durable, and structurally short of operators in most regions. Every one of these has a customer who already knows they have the problem.

11. EV charger installation for a qualified electrician.
12. Handyman subscription sold to landlords and letting agents.
13. Gutter and roof maintenance on a seasonal round.
14. Damp and drainage diagnostics — the diagnosis is the billable product.
15. Out-of-warranty appliance repair.
16. Small-space bathroom retrofits as a productised package.
17. Low-maintenance garden design and planting.
18. Pressure washing and exterior cleaning.
19. Locksmithing and smart-lock installation.
20. End-of-tenancy cleaning and property turnaround crews.

Local food, events and hospitality (21–30)

Lower barriers, thinner margins. The ones that work are almost always pre-order or subscription rather than walk-in, because that removes the waste that kills food businesses.

21. Micro-bakery with weekly pre-order and collection.
22. Meal prep for specific dietary needs — allergen, medical, athletic.
23. Mobile coffee cart for offices, sites and markets.
24. Supper club or private dining host.
25. Corporate lunch catering on a standing weekly order.
26. Event bar service with licensing handled for the client.
27. Speciality food import and local distribution.
28. Commercial kitchen rental by the hour to other food businesses.
29. Wedding and event coordination.
30. Food tours in your own city.

Tier 2: ideas that need light custom software (31–60)

These run mostly on standard tools, but one custom piece — a quoting calculator, a client portal, an integration between two systems — is what makes them noticeably better than the competition. That piece is a small, well-defined project, not a platform.

Energy transition and home efficiency (31–40)

This is where the steepest growth rates sit. The custom element is usually a survey-to-quote tool: capture a property's details once, produce an accurate quote and a compliance-ready record.

31. Residential solar installation.
32. Panel cleaning and performance monitoring as a recurring contract.
33. Home energy audits and retrofit planning.
34. Heat pump installation and annual servicing.
35. Insulation and draught-proofing contracting.
36. Battery storage installation and commissioning.
37. EV charger maintenance for apartment blocks and car parks.
38. Small commercial energy monitoring and reporting.
39. Wind turbine maintenance subcontracting.
40. Grant and incentive navigation for homeowners doing retrofits.

Education, training and coaching (41–50)

The custom piece here is progress tracking and certification records — the thing generic course platforms handle worst, and the thing regulated clients need most.

41. Hands-on trade skills bootcamps run locally.
42. Compliance training for one regulated sector you know well.
43. Exam prep tutoring with structured progress reporting to parents.
44. Corporate AI literacy training — practical, role-specific, not theory.
45. Language school for a professional niche (medical, legal, aviation).
46. Apprenticeship placement and employer matching.
47. Continuing professional development libraries for a profession.
48. Safety certification training and renewal reminders.
49. Executive coaching delivered as a structured programme, not ad hoc hours.
50. Kids' STEM workshops and school-holiday camps.

Creator, content and media services (51–60)

Crowded at the generic end, wide open at the specialist end. "Video editor" competes with everyone; "video editor for dental practices" competes with almost nobody.

51. Podcast production and editing for businesses.
52. Short-form video editing for local service businesses.
53. Property and hospitality photography.
54. Newsletter production for professional firms.
55. Technical documentation writing for software and hardware companies.
56. Localisation and subtitling for a specific language pair.
57. Brand identity studio serving trades and service businesses.
58. Drone survey and aerial media.
59. Community management for niche paid memberships.
60. Course production for subject experts who cannot self-produce.

The ideas that fail are rarely the boring ones. They are the ones whose founder budgeted for a website and bought a software company.

Tier 3: ideas that need real custom software (61–80)

Here the internal system is what lets you deliver at a price or quality the incumbents cannot. You are not selling software — you are selling a service that would be unprofitable without it. Budget for a substantial build and ongoing maintenance.

AI-assisted professional services (61–70)

The pattern: a service traditionally priced by the hour, delivered faster because a well-built internal pipeline handles the repetitive 70%. The human still signs off — that is what the client is paying for and, in regulated work, what the law requires.

61. Bookkeeping practice with automated reconciliation and exception review.
62. Legal document review narrowed to one contract type.
63. Insurance claims documentation and evidence packaging.
64. Medical billing and coding practice.
65. Grant writing with a structured research and matching pipeline.
66. Recruitment sourcing with consistent structured screening.
67. Market and competitor monitoring delivered as a subscription report.
68. Property valuation and comparables analysis.
69. Regulatory filing preparation for a specific filing type.
70. Domain-specific translation with a real quality-control layer.

Cybersecurity and compliance services (71–80)

Backed by the strongest technical growth figure in the BLS projections. Most of these need real expertise before they need software — but they do not scale past a handful of clients without it.

71. Security assessments for small firms, sold as a fixed-price package.
72. Managed backup and disaster recovery.
73. Phishing simulation and staff training programmes.
74. Compliance readiness (SOC 2, ISO 27001) for startups.
75. Incident response retainers for small and mid-sized businesses.
76. Vendor security questionnaire completion as a service.
77. Access review and offboarding audits — a genuinely common gap.
78. Data protection and privacy consulting.
79. Penetration testing for web applications.
80. Device management for distributed teams.

Tier 4: ideas where the software is the product (81–100)

These are software companies. They carry the longest path to revenue and the highest ceiling, and they should be funded and staffed as products rather than side projects. If you are picking from this tier, read our breakdown of what a SaaS MVP actually costs before committing to anything.

Vertical B2B micro-SaaS (81–90)

The winning pattern is narrow: one trade, one workflow, done properly. Broad tools are already well served; the gaps are in verticals too small for the incumbents to bother with.

81. Scheduling for a single trade vertical with that trade's actual rules built in.
82. Quoting and estimating for specialist contractors.
83. Compliance record-keeping for one regulated niche.
84. Inventory for perishable goods sellers.
85. Route planning for small delivery fleets.
86. Client portals for professional service firms.
87. Inspection and snagging apps for a specific trade.
88. Membership and subscription management for clubs and associations.
89. Field service dispatch for small teams.
90. Grant and funding trackers for nonprofits.

Marketplaces, data and platforms (91–100)

The hardest tier on this list. Marketplaces have a cold-start problem — neither side shows up until the other is there — and data products live or die on whether you have access nobody else does. Attempt these with a genuine unfair advantage, not just an idea.

91. Booking marketplace for one tightly defined service category.
92. Equipment rental marketplace for a specific trade.
93. Vertical job board with real screening built in.
94. Data product aggregating scattered public records.
95. Industry benchmarking service built on pooled customer data.
96. Regional procurement platform for a single sector.
97. White-label ordering platform for independent retailers.
98. API for a hard-to-access data source.
99. Analytics layer on top of an industry tool everyone already uses.
100. Community platform with paid membership tiers.

How to choose one and test it in 30 days

Pick three ideas that survive the customer-one question. Then run the cheapest possible test on each, in this order.

1. Talk to five people who would buy it. Not friends — actual prospects. Ask what they do about the problem today and what it costs them.
2. Put up a single page describing the offer and a way to enquire. One page, one action.
3. Try to make one sale before building anything. Deliver it manually, even if that is embarrassing and slow.
4. Only then decide what to automate — and automate the step you personally repeated most.

Manual delivery is the point, not a compromise. It teaches you which parts of the workflow actually matter, and every tier-two through tier-four business we have built well started as a spreadsheet somebody outgrew.

For the ideas in tiers two and three, the honest cost conversation matters more than the idea. Our practical breakdown of custom web app costs shows the line-item method we use, and business automation trends for 2026 covers which workflows are worth automating first. If you are starting in tier one, the highest-return early work is your website and enquiry flow — see the seven features every small business website needs. The wider Product Planning cluster covers scoping and estimates in depth, and our SaaS development page explains how we work with tier-four founders.

Frequently asked questions

What is the best small business to start in 2027?

There is no single best one, but the strongest combination is a sector with published growth and a customer you can already reach. On the BLS 2024–2034 projections, care services and energy retrofits lead on volume and growth rate respectively. Between two ideas you find equally appealing, pick the one where you can name three likely buyers today.

Which of these ideas can I start with no money?

Most of tier one, if you already have the skill. Service businesses in care, trades and content can begin with a phone, a simple site and a payment link. What you cannot start with no money is anything in tier four — a marketplace or SaaS product needs sustained engineering before it earns anything, and underfunding it is the most common way these fail.

Do I need custom software to start a small business?

Usually not, and starting with it is a common expensive mistake. Off-the-shelf booking, payments and accounting cover tier-one businesses completely. Custom software earns its cost when manual admin per job starts eating your margin, or when the software is the reason a customer picks you. Deliver manually first; automate the step you repeated most.

How much does it cost to take payments?

Stripe publishes 2.9% + 30¢ per successful online transaction for domestic cards and 2.7% + 5¢ in person, with 1.5% added for international cards and 1% for currency conversion. On a service business with healthy margins this is negligible; on low-margin resale it can decide viability, so model it before you set prices.

Is it too late to start in a growing sector?

Growth attracts competition — Census recorded 578,926 US business applications in July 2026 alone. The answer is not to avoid growing sectors but to narrow within them. "Solar installer" is crowded; "solar installer specialising in listed and heritage properties" is not. Specificity is the available edge for a new entrant.

How do I know which tier my idea is in?

Ask what happens if you use only generic tools. If you can deliver a good service with them, you are tier one. If there is one workflow they handle badly, tier two. If your whole delivery advantage depends on a system you would have to build, tier three. If customers would be paying for the software itself, tier four — budget accordingly.
