See what others miss

From import evidence to the next right question.

MarginMining helps ecommerce founders review shipment evidence, spot cost gaps and turn the findings into practical actions for suppliers, brokers or internal teams.

How MarginMining works

Evidence in. Cost gaps out. Action Pack ready.

Step 1

Upload evidence

Add shipment documents, invoices, duty statements, product data or landed-cost files.

Step 2

Find the gaps

MarginMining reviews the evidence with you, surfacing supported findings, missing information, HS code questions and weak landed-cost assumptions.

Step 3

Send the next question

Get a practical Action Pack with review signals, missing evidence and copy-ready questions for your broker, supplier or internal team.

What you get back

An Action Pack turns messy evidence into the next practical step.

Every Import Cost Review produces a copy-ready Action Pack: an evidence summary, supported findings and messages to send suppliers, clearance teams and your internal landed-cost file. Actions describe what the evidence supports and what still needs checking; final customs treatment sits with your clearance party.

Evidence checked

See which documents were reviewed and which evidence is still missing.

Review signals

See where duty, freight, origin, valuation or variant-cost assumptions are supported by evidence and where they still need verification.

Recommended first action

See the most useful next question to ask before the cost number is trusted downstream.

Copy-ready message

Use plain-English wording with your broker, supplier or internal team.

Import tools

Use import tools when evidence needs cleanup.

Import Cost Review is the main workflow. Import tools help prepare cleaner evidence before running or updating a review.

HS Checker

Sense-check classification questions before duty assumptions are trusted.

SKU Mapper

Beta

Match supplier item codes to Shopify SKUs for landed-cost exports.

DOC Converter

Beta

Convert invoices, scans and broker documents into structured rows.

Evidence first. Never customs guesswork.

MarginMining does not provide customs, tax or legal advice.

It organises evidence, highlights review signals and prepares questions you can raise with your broker, supplier or internal team.

Source-backed signals

Review signals are framed around evidence so you can see why a question was raised.

Evidence-led wording

Findings describe what the evidence supports and what still needs checking. They are not final customs, duty or eligibility outcomes.

You stay in control

Use the findings to decide what to review, what to ask and who to involve.

Start with the cost question in front of you.

Review your last shipment and get an Action Pack showing what is missing, what to question and who to ask.
