Business idea validation checklist — 12 steps before you build

Why a checklist matters more than a gut call

Most failed startups skipped validation not because they didn't care, but because “validate the idea” is vague advice. This checklist gives you twelve specific questions to answer — each producing a concrete artefact you can point to later. Work through them in order. By the time you reach the end, you'll either have a Ship-grade brief or a clear understanding of why this isn't the right idea.

The 12-step checklist

1. Name the exact buyer

Not “small businesses.” Not “teams.” Name them specifically: “owner-operators of 3–10 location restaurant chains in the UK,” or “procurement managers at mid-market manufacturers with £20–100M revenue.”
Artefact: one-sentence buyer description with industry + role + scale.

2. State the exact pain in their words

Talk to five buyers and use their language. “Reconciling invoices across three systems eats a full Friday every month.” The specific words matter — they become your headline copy later.
Artefact: five quoted phrases from real buyer conversations.

3. Identify the urgency trigger

Why would they buy now vs in six months? Common triggers: a new compliance deadline, recent staff departure, a recent costly mistake, a measurable financial drag. Without urgency, even a real pain stays unsold.
Artefact:one-line description of the “why now” event.

4. Estimate willingness to pay

Don't ask “would you pay X?” — that produces social-desirability lies. Ask “what are you spending on this problem today, and how is that going?” Their answer reveals the budget envelope. Look for £500/month or more in commercial buyer budgets — anything below that is hard to scale.
Artefact: estimated monthly budget envelope per buyer.

5. Map direct competitors

List every company already selling something similar to this buyer. If you can't name at least three, you haven't looked hard enough. If you can name twenty, the category is saturated — you need a wedge.
Artefact: table of 5–15 competitors with price, target buyer, and known weakness.

6. Identify your defensibility moat

What stops a well-funded competitor from copying you in six months? Options that compound: proprietary data, workflow integration depth, regulatory licences, network effects, an existing audience. Features alone don't qualify.
Artefact:one-sentence statement of your moat (or honest admission you don't have one yet).

7. Define your first acquisition channel

Not “digital marketing.” Not “social media.” Specifically: which trade group, Slack community, conference, partner network, or LinkedIn segment will produce your first 10 customers? If the answer is paid ads, you're structurally weak.
Artefact: named channel + outreach playbook.

8. Sketch the pricing model

Monthly subscription? Per-seat? Per-transaction? Outcome-based? Pick one and price it specifically. Vague pricing kills the deal. Use the price your buyer's budget envelope from step 4 actually supports.
Artefact: price point + cadence + tier structure (e.g. £400/month per location, annual prepay 15% discount).

9. Estimate speed to MVP

Can you ship the first usable version in 2–4 weeks? If it's 3+ months, your iteration loop is too slow for early-stage validation. Either narrow the scope or accept the execution risk.
Artefact:realistic timeline + scope cut you'd make if needed.

10. Confirm legal and regulatory feasibility

Especially for fintech, healthcare, legal, food, and energy ideas. Some categories require explicit licences before you can sell. Confirm now — discovering a licensing block six months in is fatal.
Artefact: list of required licences/registrations + their cost and timeline.

11. Get one buyer to pre-commit

Before any meaningful product build, secure one buyer who's willing to pay (even at a discount) once you ship. A signed LOI, a deposit, or a verbal commitment with a named decision timeline. This step kills more ideas than any other — and that's exactly why it's on the list.
Artefact: at least one buyer pre-commitment in writing.

12. Run the full validator

Paste your artefacts into Skip or Ship and get a final verdict + per-category scores. The categories where you score low against the validator's rubric tell you exactly what still needs work.
Artefact: Ship, Fix, or Skip verdict + screenshot for your own records.

How to use this checklist in practice

Two patterns work well: 1) Work the list top-to-bottom in one focused session (2–3 hours) before any product build. 2) Spend a week gathering each artefact properly, then return to compile them. Pattern 1 catches obviously-weak ideas fast. Pattern 2 produces a stronger brief but takes longer.

Either way, by step 11 you should already know whether this idea has legs. If five buyers gave you concrete pain quotes and one of them pre-committed, you have a real opportunity. If you struggle to name even one specific buyer, that's the data — keep iterating.

Common reasons ideas fail this checklist

• Step 1 fails:buyer is “small businesses” or “teams” — too generic. Fix: narrow to a vertical + role + scale.
• Step 6 fails:the only moat is “we'll execute better.” Fix: identify a structural defensibility lever before building.
• Step 7 fails:channel is “social media” or “SEO.” Fix: name the exact community, group, or partner. If you can't, the idea has a distribution problem.
• Step 11 fails:no buyer will pre-commit. Fix: this is the strongest signal available — either the pain isn't real, the urgency isn't there, or you haven't earned trust yet. Don't paper over it.
