Catalog data preparation & reconciliation
Your supplier list and your store export, reconciled line by line.
Product catalog reconciliation for e-commerce teams. We compare supplier spreadsheets with your store export and deliver clear change reports, exception lists, and traceable review files — without making any changes to your live store.

Electronic delivery only. No physical goods, no logistics, no payment handling on your behalf.
What we do
- NormalizeSupplier product rows are cleaned and standardized into one consistent shape — titles, identifiers, units, categories.
- MatchSupplier records are matched against your store export by SKU, barcode or fuzzy title, with the matching rule stated in the report.
- CompareField-by-field comparison: price, currency, stock, pack size, variant and attribute values.
- ReportA discrepancy and exception report in spreadsheet form, plus a short summary of the highest-impact issues.
- ExplainEvery row in the report carries the reason it was flagged, so a non-technical colleague can review it.
Built for overseas e-commerce teams and the agencies that build and run their stores. We work from files you already have — no system access, no integrations, no changes to your store.
What you receive — and a sample of it
- Change reportOne structured spreadsheet listing every difference between the supplier data and your store export, row by row.
- Exception listThe records that could not be matched, or that break a rule you set — called out separately so nothing is silently dropped.
- Traceable review fileEach flagged row carries the field, both values, the matching rule applied and the reason it was flagged, so any colleague can check the finding.
- Short summaryThe highest-impact issues first, in plain language, at the top of the workbook.
These are review files for your team to act on. We do not import anything into your store, change listings, or touch your live systems.

US$199

- One revision pass per batch within 7 days
Available only after two paid deliveries for the same store.
Prices are in US dollars and exclude any bank or transfer fees charged by your side. One store per batch. Volume is counted in source records, not item counts — variants and duplicate source rows both count toward the batch limit, and the reference store export may be up to 5,000 rows. Files are quoted from the record counts you send us; if a file turns out to be larger than described, we tell you before doing any work.
How it works
- Email us the files. Send one store export and one or more supplier lists (CSV or XLSX).
- We confirm the scope. You get a written quote stating record counts, what will be compared and the delivery date.
- We invoice. The invoice carries the payment options available for your country.
- We process and deliver. Trial batches within 2 business days, standard batches within 3 business days — counted from scope confirmation and payment, whichever comes later.
- One revision pass. If a discrepancy in our own matching is wrong, we correct it within 7 days at no cost.
Every deliverable is a review file: it states what differs and what to check, and it is never imported into your store on your behalf. Order taking starts with a written scope confirmation — that is what keeps the price fixed and the output predictable.
Your data
- PurposeYour files are used only to produce the report you ordered. Nothing else.
- RetentionInput and output files are deleted 30 days after delivery unless you ask us to keep them longer.
- No resale, no reuseYour data is never sold, published, or used to produce work for anyone else.
- ProcessingOur own matching software does the comparison; the output is reviewed by a person before it is sent.
- No system accessWe never ask for credentials to your store, ERP or supplier accounts.
Routine correspondence may be handled with the help of a third-party AI language model; your product files are processed only by our matching software. A short data-processing agreement or NDA can be signed before the first batch on request.
