Exceptions report for unresolved records
Quantities, row order and unrelated columns are preserved. Names and prices change only when the exact SKU resolves to one valid master record.
Scope and timing
One inventory CSV and one authoritative master CSV, up to 500 inventory rows and 8 columns. One consolidated correction against the agreed matching rules.
Target delivery: two business days after the scope, complete files and payment are received. Final scope, availability and payment arrangement are agreed before an invoice. PayPal goods and services.
BEFORE ORDERING
Start with a small sample.
Email the row count, column headers, required output format and deadline. The master file should include SKU, product name, price and currency. Preserve SKU values as text, including leading zeros.
Product data is sufficient; customer, payment and account details are not needed. Send only data you have permission to share.
This service does not access live stores, scrape websites or provide ongoing maintenance. Review or approve flagged records before uploading the final inventory to your store.
