Price Margin Rules in Zelph
Price Margin Rules automate the markup your trusted sellers must apply to their prices. You define your target profit margin per price band, and Zelph calculates the required selling price on every variant — so trusted sellers always price in a way that protects your margin.
Price Margin Rules is part of the Zelph Seller Network, available on the Consignment plan.
Where to find it
Go to Seller Network > Price Margin Rules in the sidebar. You’ll see a table of every rule ordered by priority (lowest priority number applied first), showing the price band, target margin %, and priority.
How a rule works
Each rule says: “For variants whose cost price falls between £X and £Y, the selling price must achieve at least Z% margin after my commission.”
When a trusted seller lists or updates a variant, Zelph walks the rules in priority order until it finds one whose price band matches. The first matching rule wins; the rule’s target margin is then used to calculate the required selling price.
Creating a rule
- Click Create.
- Fill in:
- Minimum price — the lowest cost price this rule applies to.
- Maximum price — the highest cost price this rule applies to. Leave blank for “and above”.
- Target margin (%) — your desired profit margin, between 0 and 100.
- Priority — lower numbers are evaluated first. Use this to control which rule wins when bands overlap.
- Click Save.
The form shows the typical seller commission rate and warns you if your target margin is lower than the seller’s handling fee — in which case the rule won’t apply.
Example setup
| Priority | Price band | Target margin |
|---|---|---|
| 1 | £0 – £49.99 | 30% |
| 2 | £50.00 – £199.99 | 20% |
| 3 | £200.00 and above | 15% |
With these rules, a £120 variant must be priced to yield at least 20% margin after commission.
Reordering rules
Drag the position handle on each row in the table to reorder rules by priority. The system will re-evaluate every variant against the new order on the next sync.
Editing or deleting a rule
- Edit — change the price band, target margin, or priority.
- Delete — remove the rule entirely.
Changes apply on the next price sync to trusted sellers’ variants.
When rules apply
- Rules apply only to trusted sellers. Non-trusted sellers use the price rounding configured under your workspace’s Seller Network settings.
- If no rule matches a variant’s cost price, the system falls back to your default pricing strategy.
- Rules don’t apply if the target margin would be lower than the seller’s handling fee — Zelph will skip and try the next rule.
Tips
- Cover your entire price range with rules so no variant slips through.
- Set higher target margins on cheaper items where commission is a larger share of the total.
- Lower target margins on premium items where competitive pricing matters more.
