When supplier headers, option structures and identifiers do not match the target catalog, “just import the spreadsheet” is not a process. The managed service builds a bounded transformation with explicit exceptions.
ShadowOrders product: Supplier Catalog Processing. This page describes one specific use case; the technical boundary is the same as the underlying product.
Rows are mapped and validated, SKU/variant relationships are checked, unsupported or ambiguous data stays visible as exceptions, and buyer-safe sample artifacts show the output shape before a larger scope.
For an early structural look, use the public catalog risk check. For real conversion scope, send a representative supplier file and receive a feasibility/scope response before payment.
Static preparation only in the standard scope. ShadowOrders does not require a Shopify password and does not promise a live import.
