You will get Cross-Platform SKU Matching / Master SKU Crosswalk
Project details
I create a verified master SKU crosswalk across product catalogs, marketplace exports, supplier files, or business systems.
Using identifiers you provide—SKU, GTIN/EAN/UPC, manufacturer part number, product title, and variant. I standardize the files and map each source product to the correct master SKU.
Reliable exact matches go into the approved crosswalk. Likely matches, duplicate SKUs, variant conflicts, and unmatched records go into a human-reviewed exception queue. Each flag includes the reason, candidate, and recommended next step. I review included exceptions and sample-check approved matches.
You receive:
• Approved source-to-master SKU crosswalk
• Match method and approval status
• Human-reviewed exception queue
• Duplicate, conflict, and unmatched reports
• Source references, matching rules, and review notes
Original files remain unchanged. I never force uncertain matches or invent missing identifiers. Unconfirmed mappings are marked Review Required for your decision.
This is file-based catalog mapping. Inventory reconciliation, price updates, marketplace uploads, API integration, and permanent synchronization are not included.

About Kashan
Business Research & Data Validation | Data Analysis & Reconciliation
Oyama, Japan - 1:31 am local time
That practical experience is what led me into broader business research and data work.
I help clients with research, data validation, comparison, analysis, and reconciliation. Sometimes that means finding and organizing supplier or market information. Other times it means cleaning a spreadsheet, comparing two files, checking why records don’t match, or finding missing, duplicate, and inconsistent data.
I work mainly with Excel, CSV files, business records, supplier data, pricing information, and structured exports.
My approach is simple: I keep the original data intact, avoid guessing when something is unclear, and flag anything that needs attention. For larger datasets, I use tools to handle the repetitive work efficiently, then review the exceptions and spot-check the results before delivery.
The goal is not to give you another complicated spreadsheet. It’s to give you a clear result showing what was checked, what matches, what doesn’t, and what needs your attention.
If you have business data, research, spreadsheets, or records that need to be checked, compared, cleaned up, or organized, feel free to send them over.
Steps for completing your project
After purchasing the project, send requirements so Kashan can start the project.
Delivery time starts when Kashan receives requirements from you.
Kashan works on your project following the steps below.
Revisions may occur after the delivery date.
Files and scope are confirmed
You provide the source catalogs and master or reference catalog, if available. I check the file formats, combined row count, available identifiers and package scope.
Master SKU and matching rules are confirmed
We confirm which file and column contain the approved master SKU. I also review any SKU aliases, bundles, duplicates, exclusions or special variant rules you provide.
