Change product taxes for the whole catalog, confidently, not blindly.
A guided wizard to bulk-update customer and vendor taxes — plus category, accounts, price and cost — across hundreds of products, with a full before/after preview, an explicit confirmation gate and a permanent audit trail.
The problem
When VAT/GST rates change, a company enters a new jurisdiction, or a product line is reclassified, taxes must be updated on every affected product. Odoo has no native bulk-safe way to do this: editing product-by-product is slow and risky, and a mistake propagates onto every quotation, invoice and purchase order that uses the product. There is no preview of what will change and no record of what changed afterward.
The solution
A guided wizard lets you select products, choose how customer and vendor taxes (and related fields) should change, review a side-by-side before/after preview, and confirm explicitly before anything is written. Every run is logged with old-to-new values, and recurring changes can be saved as reusable templates.
Everything a bulk tax change needs
Every capability below is implemented in the module.
Bulk customer & vendor tax updates
Replace, add, remove or clear sales and purchase taxes across many products in a single guided operation.
Combined sales + purchase change
Update customer and vendor taxes together in one pass instead of running two separate operations.
Related-field bulk edits
Adjust product category, income/expense accounts, sales price and cost in the same operation as the tax change.
Before/after preview
See a side-by-side list of every affected product with its current and proposed values before anything is committed.
Explicit confirmation gate
Nothing is written until you explicitly confirm, preventing accidental mass changes to live catalog data.
Variant-aware updates
Tax and field changes apply reliably across product variants, not just top-level templates, for variant-heavy catalogs.
Saved configuration templates
Save a bulk operation as a reusable template and run it again later without reconfiguring from scratch.
Persistent audit trail
Every bulk run is logged with who changed what, when, and the old-to-new value per product — and survives later tax or product renames.
Two entry points
Launch the wizard from the dedicated app menu or directly from the product list Action menu, wherever you already are.
How it works
Select products
Start from the dedicated app menu or the product list Action menu, or load a saved configuration.
Configure the change

Preview the impact
Review a before/after list of every affected product before anything is written.
Confirm & track
Confirm to apply, then find the run in the audit trail with full old-to-new values.
Frequently asked
No sales fog. If your question isn't here, email us and we'll answer it the same way.
Yes. The wizard lets you replace, add, remove or clear customer (sales) and vendor (purchase) taxes in the same operation, so you do not need to run the tool twice.
