Comparison report
Changes to review
A row missing from the supplier file is not a deletion instruction. Duplicate or blank SKUs stay unresolved.
| Status | SKU | Current catalogue | Supplier proposed | Source evidence |

Supported files and limits
Use a product CSV with one row per SKU where possible. You can map Shopify export columns such as Variant SKU and Variant Price. Extra image rows, repeated variants and fields that are not mapped need separate review. The tool compares text values; it does not import files or verify Shopify acceptance.
A scoped second look
Want the file checked for you?
For £195, we review one supplier file against one current catalogue, up to 250 SKUs or variants. The paid work includes agreeing the mappings, investigating unclear rows and returning an explained change report. The free tool above is available without purchasing the service.
Describe the job first. We will agree the files, deliverable and timing before payment.
