CostHarbor Supplier Updates for WooCommerce

Description

CostHarbor Supplier Updates for WooCommerce generates an editable catalog CSV template and safely imports supplier cost updates for products and variations. Every import is previewed before Apply, with dangerous regular-price changes warned and invalid rows blocked.

Supplier Cost is retained by CostHarbor and synchronized through WooCommerce’s public native Cost of Goods methods when available. Applied Supplier Cost and calculated Regular Price changes can be rolled back, and CSV or store data is never sent to an external server.

It matches both product and variation SKUs. It never creates products. Invalid, duplicate, and unmatched rows are blocked. Large proposed price changes are highlighted using a configurable threshold. Every apply stores the prior supplier cost and regular price for rollback.

All processing and data storage stays in WordPress and WooCommerce. The plugin sends no telemetry, analytics, CSV content, or store data to external services.

Privacy

CostHarbor Supplier Updates for WooCommerce processes CSV content locally and stores import summaries, rollback snapshots, and supplier cost metadata in the site’s WordPress database. It does not transmit data externally. Import history is retained for the 20 most recent imports. By default, uninstalling preserves supplier costs and import history as business data while removing temporary data. Administrators can explicitly opt into permanent data deletion before uninstalling.

Does it change products immediately after upload?

No. There is no direct apply path. You must create and review a preview, then explicitly apply safe rows.

How do I create my first supplier CSV?

Open WooCommerce > CostHarbor Supplier Updates for WooCommerce and select Download catalog template. Fill the Supplier Cost column for the product and variation SKUs you want to update, save the CSV, then upload it and build a Preview before applying anything. A blank template is also available.

Does it create products for unknown SKUs?

No. Unknown SKUs are blocked and skipped.

Are variation SKUs supported?

Yes. Matching uses WooCommerce’s public SKU lookup, which includes variations.

Where is supplier cost stored?

The plugin keeps its own product metadata as the durable source of truth. If the installed WooCommerce exposes its public Cost of Goods methods, the value is also synchronized through those methods. No private WooCommerce metadata is accessed.

What does rollback change?

Only the CostHarbor Supplier Updates for WooCommerce cost and the regular price that the selected import changed. It does not restore titles, stock, sale prices, or unrelated metadata.

What CSV formats are supported?

Comma, semicolon, tab, and pipe delimiters are detected. UTF-8 is preferred; common legacy encodings are converted when PHP’s multibyte extension is available. Files are limited to 10 MB and 10,000 data rows.

Does the plugin contact external servers?

No. Version 0.1.3 has no external requests, telemetry, analytics, or remote imports.
