Slippage → One-off analysis

You have the question. You have the data. Nobody has the week.

Not everything needs a system. Sometimes there's one specific thing the business needs to know, the data to answer it already exists in exports, and the only missing ingredient is somebody with an uninterrupted week and no other job that month.

One question, answered in a week: $1,800. $900 for the first three.

Examples

The questions that come up most

Where margin actually goes

Contribution by channel, by SKU family, after shipping, returns, discounts and fulfilment cost — not the version that stops at gross.

Why returns moved

Which products, which reasons, which cohort, and whether the change is a product problem, a sizing problem or a photography problem.

Which SKUs stopped paying

Slow movers that still occupy pallet positions and working capital, ranked by what they cost to keep.

What peak actually costs

Surcharges, overtime, split shipments, expedites — assembled from the invoices and the shipment log after the season, while it's still arguable.

Whether a 3PL is performing

On-time, accuracy, cost per order over time against what was promised, in a form you can put in front of them.

Is the discount working

Incrementality on a promotion, done honestly: what would likely have sold anyway, and what the discount bought.

A worked example

“Which channel is actually profitable?” — what the week looks like

The most common question we get, and a good illustration of why the answer takes a week rather than an afternoon: the question contains four decisions before any arithmetic happens.

Decide what “profitable” includes

Product cost and shipping, obviously. Then: fulfilment per order, payment fees at 1.5–3.5% depending on channel, returns at whatever your rate actually is, discounting, marketplace commission at 8–15%, and advertising — which is where most channel comparisons quietly break, because platform-reported attribution flatters the channel that reports it.

Reconcile before analysing

Channel revenue in the store rarely equals channel revenue in accounting: settlement timing, refunds, gift cards, tax treatment. If the two disagree by more than a percent or two, the analysis waits until we know why — otherwise the conclusion inherits the error.

Attribute the shared costs honestly

Warehouse minimums, storage, software, the person who handles wholesale paperwork. Allocated per order, per unit or per revenue dollar — the choice changes which channel looks worst, so it is made explicitly and stated in the answer rather than buried.

Test whether the answer survives

Re-run on a different period and a different allocation basis. A conclusion that flips when storage is allocated per unit instead of per order is a conclusion with a caveat attached, and you get told that instead of a clean chart.

Typical outcome: one channel is 5–15 percentage points worse than the reported view, usually wholesale once the paperwork and compliance costs land, or marketplace once commission, returns and storage are counted properly. Sometimes the answer is “they are within noise of each other and the real question is something else” — that is a legitimate result and you still get the working.

How it runs

A week, start to finish

Day one — agree the question

Thirty minutes to make it precise enough to answer. Most vague questions have a sharp one hiding inside, and finding it is half the work.

Days two and three — the data

You send exports. We check whether they can actually answer the question, and say so early if they can't rather than at the end.

Days four and five — the work

The analysis, plus the checks that make it trustworthy: does the total reconcile, does the sample match, does the conclusion survive a different cut.

End of the week — the answer

A short written answer with the number, the working, the caveats, and the file so somebody can re-run it next quarter.

Price

Fixed, per question

One question
$1,800
one week, one specific question
  • Written answer with the working shown
  • The data file, so it's repeatable
  • Caveats stated, not buried
  • If the data can't answer it, we stop and refund the balance

Two or three questions in a row usually means you want reporting instead — the same money spent once answers them repeatedly. We'll say so rather than selling four analyses.

Standard

What "with the working" means

Analysis without visible working is just an opinion with charts. Every answer we send includes four things, because without them you can't tell a good answer from a confident one.

The reconciliation
Totals in the analysis tie back to a number you already trust, and we show that tie
The exclusions
What was dropped and why — cancelled orders, test SKUs, the month the system changed
The sensitivity
Whether the conclusion survives a different cut, and where it stops holding
The honest gap
What the data cannot tell you, stated plainly, so nobody builds a decision on a hole
Questions

The ones that come up

Our data is messy. Is that a problem?

It's the normal starting condition. Messy is workable; ambiguous is the real risk — when there's no way to tell which of two records is the truth. We flag that in the first two days rather than discovering it at the end.

Can you sign an NDA?

Yes, mutual, before anything is sent. And the smaller protection matters more: strip customer names and addresses from the exports. We almost never need them.

What if we don't like the answer?

You still get it. We don't tune conclusions to what the buyer hoped for — an analysis that always agrees with you is worth nothing, and you'd find out the expensive way.

How to start

Two lines by email. No form, no calendar link.

Which two systems, roughly what size, what you have already tried. You get a straight answer the same working day — including “this is not something we would help with”, when that is the honest one.
