01Define the item and hierarchy
Decide what the customer can buy as one offer and assign a stable internal ID to each sellable variant. Map product family, style or model, color, size, pack count and bundle relationships explicitly. Do not create a new identity merely to fix text, and never reuse an old ID for a different product. Record discontinued and replacement status without deleting history.
02Resolve identifier ownership
Record GTIN, MPN, brand and supplier model exactly as issued, plus issuer, allocation date, check result and packaging level. Mark not assigned, pending and not applicable differently. An internal SKU is useful for operations but should not be presented as a manufacturer or GS1 identifier. Review identifier changes against current allocation rules and trading-partner requirements.
03Capture sourced product facts
Build fields for controlled name, plain description, category, condition, composition or material wording, dimensions, weight, intended use, included items, care or setup information and country of origin where evidence exists. Store value, unit, measurement object, method, source document, owner and review date. Keep unknown values blank rather than inheriting them from a related model.
04Separate pack and logistics data
Distinguish the consumer unit from inner pack, case, shipping carton and pallet. For each level, record identifier, contained quantity, net and gross measures, dimensions, package type and marks using named methods. Reconcile hierarchy multiplication. A product dimension must not be replaced with a carton dimension, and a case GTIN must not be attached to the individual item.
05Govern images and claims
List primary, alternate, detail, package and lifestyle images with file owner, rights status, represented variant, revision and approved use. Tie performance, compatibility, material, safety, sustainability, authenticity and other claims to specific evidence and allowed wording. Product-data completeness is not permission to publish an unsupported field, logo or third-party image.
06Map and validate each channel
Create a mapping table from source field to retailer or platform field, allowed value, format, unit, language, requirement and transformation. Validate unique IDs, variant groups, checksums, mandatory values, URL access, image match and category-specific fields. Export a test set first. Keep rejection messages with the exact submitted version and fix the authoritative source when the error is factual.
07Reconcile the live listing
Compare the accepted feed, retailer record and visible page with the approved master and packaging. Check title, variant selection, identifiers, images, condition, dimensions, included items and evidence-controlled copy. Assign update frequency and owners separately for slow product facts and fast commercial data. Retire items deliberately and preserve prior submissions, acknowledgements and correction history.
