Product Prices

Access from: Catalog → Products

Epinium lets you edit your product prices from within the platform and publish them to Amazon. It supports per-audience pricing (ALL and B2B), automatic currency conversion, and validates changes against the min/max limits configured in Seller Central.

Audiences

Each product can have up to two concurrent prices depending on the audience:

Audience	Applies to
ALL	Standard price for any buyer (B2C). Must always be present for the product to be sellable.
B2B	Specific price for Amazon Business customers. Optional — if omitted, B2B buyers see the ALL price.

If you leave B2B empty on a product that had a B2B price, Epinium removes the entry and B2B buyers fall back to the ALL price.

Min/max limits (Seller Allowed Price)

Each audience can have a minimum allowed price and a maximum allowed price. They act as a safety net: if you try to save a price outside the range the change is discarded and not written to the product.

• If you set only the minimum, any price below it is rejected.
• If you set only the maximum, any price above it is rejected.
• With no min/max there is no validation — any value ≥ 0 is accepted.

These limits are per-audience: ALL and B2B each have their own independent min/max.

Ways to edit the price

1. Manual edit from the product detail

1. Open the product detail from the table.
2. Go to the Properties tab.
3. Expand the purchasable_offer node. You'll see two rows (ALL and B2B), each with: price, minimum allowed, maximum allowed.
4. Edit the value you want.
5. Click Save.

If you enter a price outside the min/max range a warning appears under the field and the save discards that value (other changes in the form are still saved).

2. Bulk edit — Fixed value

Apply the same price to several products at once:

1. Select the products in the table.
2. Open the bulk edit panel → Price → Set.
3. Provide the value, currency, and audience (ALL or B2B).
4. Confirm and publish.

Currency conversion: if the selected products have currencies different from the one you entered, Epinium converts the price automatically using the current exchange rate of each marketplace. Example: you set 20 EUR on UK (GBP) products → the GBP equivalent is stored.

Special rules:

• ALL empty or 0 → the product is not modified (ALL is required).
• B2B empty or 0 on a product that had B2B → the B2B entry is removed.

3. Bulk edit — Increment / Discount

Apply a relative adjustment over the current price:

1. Select the products.
2. Open the bulk edit panel → Price → Increment.
3. Configure:
   • Type: percentage or absolute value.
   • Direction: increase or decrease.
   • Amount: e.g. 10 for +10% or -10€.
   • Target audience: ALL or B2B.
   • Based on: which price is the calculation based on (usually the same audience; you can also base B2B on ALL to auto-apply a discount for business customers).
   • Cap (optional): if the result exceeds this cap, it is clamped to the cap.

Example: "Raise the ALL price 5% for all products of brand X, capped at €80".

Validations and behaviour

Across all editing modes:

• If the computed price falls outside the audience's min/max range, the change is discarded and the product is flagged as "not affected" (not marked as pending publish).
• If the audience doesn't exist yet (e.g. adding B2B for the first time), Epinium creates it.
• Changes stay in the pending publish state until you confirm publishing to Amazon from the publish section.

Price change history

Every price modification generates an entry in the change history with the exact detail of which audience and which field (price, min, max) was touched. You can revert any change from there.

Publishing to Amazon

Prices edited in Epinium are not published automatically. They follow the same flow as other changes:

1. Saved in Epinium as pending publish.
2. Go to Publish changes from the catalog.
3. Review and select the price changes you want to send.
4. Confirm. Epinium pushes them to Amazon via Seller Central or Vendor Central and the listing updates within minutes.
