Build your own repricing rule

This article walks through the rule builder in Repricer → Rules, so you can create a custom pricing rule that fits how you actually sell, rather than relying only on the built in strategies.

The two-step builder

Opening a new or existing rule takes you through a two-step editor: 1 · Basic and 2 · Advanced. The Basic step is where you name the rule and set up its conditions, its price action, and what it applies to. The Advanced step is where you set this rule’s own price guards, its priority against other rules, and whether it is active or paused.

Step 1: set your conditions

Under “When all of these are true”, add one or more conditions. Each condition is a field, a comparison, and a value, for example “days listed is greater than or equal to 30”. All the conditions you add must be true together before the rule fires.

The fields available to build conditions from are your own listing and order data, including:

• Listing age (days listed)
• Days since last sale
• Stock level
• Current price
• Margin
• Profit
• Cost of goods sold (COGS)

Step 2: choose the price action

Under “Then adjust the price”, choose what should happen to the price when the conditions above are met, for example reducing it by a percentage or by a fixed amount. You can add more than one action to a single rule if you want several adjustments to apply together.

Scope: what the rule applies to

Every rule needs a scope, set in the “Applies to” field on the Basic step. Your choices are:

1. All listings, so the rule is checked against everything you sell.
2. A specific eBay category, so the rule only checks listings in that category.
3. A purchase source, so the rule only checks listings tagged with that source.

Narrowing the scope is useful when a pricing behaviour should only apply to part of your catalogue, such as one supplier’s stock or one category that moves differently to the rest.

The Advanced step

Press Next to move to the Advanced step. This is where a rule’s own price guards, its priority, and its Active or Paused status live, along with a read-only reminder of the account-wide safety limits that always apply on top.

This rule’s own floor and ceiling

At the top of the Advanced step, under “Price guards for this rule”, you can set a “Never price below” and a “Never price above” value. These are optional guards that this rule alone will not cross, regardless of what its conditions and price action would otherwise produce.

Leave either field blank (they show as “auto”) to fall back to that listing’s own floor or ceiling and your COGS-based default instead of a fixed number for this rule.

Priority: when more than one rule matches

Below the guards, every rule has a priority number. If more than one of your rules matches the same listing at the same time, the rule with the lower priority number runs first. Use priority to control which rule “wins” when your rules overlap, rather than leaving the outcome to chance.

Next to priority is the Status switch, which reads Active or Paused, so you can build and save a rule without it running yet.
