What our clients say
Bulk pricing that respects your margins
The mass price editor changes prices at catalog scale while honouring the min/max range configured per product — anything that would fall outside the range is left untouched, so you never publish an out-of-margin price.
From bulk edit to published price
Select products, choose how to price them, and Epinium applies the change within each product's guardrails — then you review and publish. Publishing runs on Amazon Seller Central and Vendor Central.
Fixed prices with per-product guardrails
- Establish tabType the selling price, pick the currency and the audience (ALL or B2B). Empty means no change — nothing is wiped.
- Min & max limitsSet or, with the trash icon, remove a limit per product. Any resulting price outside the range marks that product as not affected.
- Reactive validationThe editor blocks a price below the min, above the max, or a min above the max before you can apply — no broken ranges.
Raise or discount by % or amount
- Increase/Decrease tabApply a relative adjustment — percentage or absolute value, up or down — over the current price of every selected product.
- Based on any audienceBase the B2B price on the ALL price to auto-apply a business discount (e.g. "B2B = ALL − 8%").
- Result capOptionally cap the result so a bulk raise never pushes a price past a ceiling you set.
Review, then publish
- Pending publishPrice edits stay in Epinium as pending publish until you confirm — nothing is published automatically.
- Sync to Seller/VendorApproved prices are pushed via the Amazon feed; removing a B2B offer or a min/max limit is handled correctly at the feed level.
- Revert anytimeEvery change is in the history with the exact audience and field touched — roll any of them back.

ExploreFrequently asked questions
What happens if a bulk price falls outside a product's min/max?
That product is marked as not affected and left unchanged — the range is a safety net, so an out-of-margin price is never written or published. Other products in the same bulk still apply.
Can I price B2C and B2B differently?
Yes. Each product can hold both an ALL (B2C) price and a B2B (Amazon Business) price, each with its own amount and min/max. You can also copy one audience's whole policy onto the other in one action.
Does it handle different marketplace currencies?
Yes. Enter one amount and Epinium converts it to each product's marketplace currency automatically using the current exchange rate — e.g. 20 EUR set on UK products stores the GBP equivalent.
Are price changes published automatically?
No. Edits stay in a pending publish state in Epinium. You review them and confirm publishing to Amazon Seller Central or Vendor Central; the listing updates within minutes.
Which sales channels can I publish prices to?
Amazon Seller Central and Vendor Central, including Amazon Business (B2B) prices. On Shopify and WooCommerce, your assistant checks prices, products and inventory live through Epinium MCP; price changes are applied on Amazon.
