Flapen cover for New seller audit checklist from an agency: a Flapen operator walking a client through product samples at a factory table

A new seller audit is different from an account audit, because there is barely any performance
data yet. It should check structure rather than results: entity and account setup, trademark
ownership, market viability, landed cost and margin, listing readiness, and inventory
planning. Six areas, in that order.

The short version

  • A new seller audit checks structure, not performance. There is no data yet.
  • Entity and account ownership first. Mistakes here are hardest to unwind.
  • Market viability before anything else operational.
  • Landed cost decides whether any of it works.
  • It should be free, and it should be useful without hiring anyone.

The six areas

I run Flapen with 50 operators managing about 70 brands. For an established account we
audit seven performance areas. For a brand-new seller those metrics do not exist yet, so the
checklist is structural.

# Area What is being checked Why here
1 Entity and account Account in your name, documents matching Hardest to unwind later
2 Brand and IP Trademark in your entity, Registry enrolled Ownership problems compound
3 Market viability Size, growth, return rate, competition Nothing else matters if this fails
4 Unit economics Landed cost, fees, margin after returns Decides whether it can work
5 Listing readiness Keyword research, primary image, bullets Caps everything downstream
6 Inventory plan Order size, lead time, reorder point Phase 1 sizing

1 and 2: structure before strategy

These come first because they are the most expensive to fix later.

The Seller Central account must be in your own legal entity with documents that match exactly.
The trademark must be filed in your name, not an agency's, and Brand Registry enrolled under
your account. If an agency offered to set up either as a convenience, this is where that
decision gets caught, and catching it now costs nothing.

3: market viability

The gate everything else depends on. Market size, growth trajectory, return rate, and whether
you can capture traffic through at least one channel.

We use a $2 million per year minimum market size as an entry floor. An audit that skips this
and goes straight to listing advice is optimizing a decision nobody has validated.

4: unit economics

Landed cost per unit, Amazon referral and FBA fees, expected return rate, and the margin that
survives all of it.

This is where a surprising number of new products fail before launch, and it is arithmetic
rather than opinion. No amount of advertising, creative, or optimization rescues a product
whose margin does not support the cost of acquiring a customer.

5 and 6: readiness

Listing readiness means keyword research done from real sources, a primary image identifiable
at thumbnail size on a phone, and bullets that answer the objections found in competitor
negative reviews.

Inventory planning means Phase 1 sizing: 200 units, with supplier lead time and freight time
understood, and a reorder point calculated rather than guessed.

What the audit should produce

A verdict, not observations. For a new seller that means one of three answers.

Proceed as planned, with a prioritized fix list. Fix first, naming the specific
structural problem, usually account ownership, trademark, or margin. Do not launch this,
with the reason, which is almost always market size or unit economics.

The third outcome is the most valuable and the least common, because it ends the sales
conversation. It is also the one that saves the most money.

What to bring to it

  1. Your product idea and target market, as specifically as you can state them.
  2. Supplier quotes including unit cost at your intended order quantity.
  3. Estimated freight and duty, even about.
  4. Your total available capital for this launch.
  5. Whether the account and trademark exist yet, and in whose name.

Point three is the one people omit, and it is the difference between a real margin
calculation and a guess. Factory quotes hide every import charge.

What most agencies will not tell you

A new seller audit is a sales conversation for most agencies, and the incentive shapes what
gets emphasized. Problems the agency can fix receive attention. Problems that mean you should
not launch receive less.

Test it by asking directly: what would make you tell me not to do this. A specific answer,
naming market size or margin thresholds, means the audit has a genuine failure mode. Vagueness
means it does not.

The other thing: a new seller audit cannot assess performance, so any claim about expected
results is a projection rather than a finding. Treat confident revenue forecasts for an
unlaunched product with appropriate skepticism, however detailed the spreadsheet.

Ask us what would make us tell you not to launch. We will answer, at Flapen.
