Ecommerce ideas live or die on unit economics that most founders don't model until it's too late: contribution margin after returns and shipping, CAC payback period, and whether there's a repeat-purchase mechanic that makes the second sale cheaper than the first.
This validator specifically checks margin structure, channel concentration risk, and retention mechanics — the three signals that separate a sustainable ecommerce brand from a Meta-ads-dependent one-hit product.
How the engine scores Ecommerce ideas
| Category | What's different for Ecommerce |
|---|---|
| Monetisation | Contribution margin after COGS, shipping, and expected returns is checked directly — below 50% is flagged as a structural risk for paid-acquisition-dependent models. |
| Defensibility | Brand and content moat, supplier exclusivity, or proprietary formulation score far higher than generic sourcing from the same suppliers everyone else uses. |
| Distribution | Channel concentration is penalised — if the plan is '100% Meta ads', that's flagged as fragile against CPM inflation and algorithm shifts. |
| Real Pain | Repeat-purchase mechanics (consumables, refills, subscriptions) score higher than one-off purchase products, since they reduce dependence on constant new-customer acquisition. |
Ecommerce benchmarks worth knowing
| Metric | Typical value | Why it matters |
|---|---|---|
| Target contribution margin | 50%+ | After COGS, shipping, and returns — needed to support paid acquisition sustainably. |
| CAC payback target | By order 2–3 | One-off, low-AOV products with no repeat mechanic rarely hit this. |
| Healthy channel concentration | Under 60% from any single paid channel | Reduces fragility to algorithm or CPM changes. |
| Typical AOV for sustainable paid acquisition | £40+ | Below this, CAC often exceeds first-order margin at current ad costs. |
Example Ecommerce verdicts
FixScore: 74/100
Subscription consumable bundle for owners of dogs with specific health conditions, vet-partnership distribution
Strong LTV via subscription, but needs a clearer wedge against established pet-health brands.
SkipScore: 24/100
Generic phone accessories sourced from AliExpress, Meta-ads only
Zero differentiation, single-channel dependence, thin margins after ad cost.
FixScore: 71/100
Premium home-office accessories with design-led branding, Pinterest and newsletter distribution
AOV supports CAC and channel is defensible, but repeat-purchase mechanic needs strengthening.

Direct answer
The Skip or Ship Idea Lifecycle System evaluates ideas with five consistent signals: market demand, competition intensity, execution difficulty, revenue potential, and customer clarity. Same inputs, same verdict — every time.
What to prove first
One buyer segment with recurring pain and a clear trigger to pay now. If that is vague, validation can't fix it.
What kills momentum
Generic ICPs, vague outcomes, and zero distribution plan. These collapse execution speed within weeks.
What to decide next
One channel, one wedge use case, one pricing hypothesis to test in the next 14 days.

Frequently asked questions
What contribution margin do I need for ecommerce to work?
Target 50%+ after COGS, shipping, and expected returns. Below that, paid acquisition rarely stays profitable once CPMs rise.
Is dropshipping still viable in 2026?
Generic dropshipping with no brand or content moat is structurally difficult — CAC has inflated while margins have compressed. Curated dropshipping with a strong brand and content engine can still work.
How important is a repeat-purchase mechanic?
Critical. Without one, every sale requires fresh paid acquisition — a subscription, refill, or accessory-pull mechanic dramatically improves LTV and reduces CAC pressure.
