Shopify Price List vs Custom Pricing vs Volume Pricing: Which Rule Wins

In BSS B2B Solution a Price List always beats Custom Pricing on the same variant, whatever the Priority numbers say. Volume Pricing then takes its tier off that price. Inside one module, the lowest Priority number (0 to 99) wins. Shopify’s native catalogs work differently: when several catalogs price one product, the lowest price displays.

Last updated October 4, 2026. Shopify facts come from the Help Center pages linked in the text. BSS B2B Solutions makes BSS B2B Solution, the app in the screenshots. This guide belongs to the wholesale pricing hub of our complete guide to Shopify B2B. If you already have a wrong price on screen, the rule priority use case is the faster debugging path.

What do a price list, custom pricing and volume pricing each do?

The three names sound alike but they answer different questions. A price list sets a fixed price per product or variant for a buyer group. Custom Pricing applies a rule such as 20% off, a fixed amount off or one price, to the products and customers you pick. Volume pricing lowers the price as the quantity in the order goes up.

Module	What it sets	Example	Plan notes
Price List	A price per product or variant for one buyer group	Product A is $38 for the gold list	Platinum
Custom Pricing	A rule: percentage off, amount off or a fixed price	20% off everything for tag wholesale	Free plan: 1 rule. More rules on paid plans. Variant-level conditions: Platinum
Volume Pricing	Tiers by quantity (or order value) on top of the base price	5% off from 12 units	Free plan: newest rule only, basic options. More options on paid plans

All three target logged-in customers, specific customers, customer tags or company locations (company-location targeting needs Advanced or higher). The tag match is forgiving: tags are trimmed and lowercased, and one matching tag is enough. Product tags used in exclusions are the exception, because they are case-sensitive.

Does Shopify have its own rule order for B2B prices?

Yes, and it is simpler. Native B2B prices through catalogs. Shopify states that if there are several catalogs and prices for a specific product, the lowest price displays to the customer (Catalogs and pricing). A catalog can hold an overall adjustment and fixed prices for chosen products, and fixed prices override the adjustment (Creating catalogs). Basic, Grow and Advanced allow up to 3 active catalogs across all B2B markets, and Plus is unlimited (plan table).

Native volume pricing has a twist. You can add up to 10 price breaks per product, and after you apply volume pricing the price becomes fixed: an overall adjustment set on the catalog no longer applies (Quantity rules and volume pricing). Automatic discounts and discount codes apply on top of catalog price adjustments (Catalog discounts).

Question	Shopify native catalogs	BSS B2B Solution
Two prices for one product	The lowest price displays	Price List beats Custom Pricing. Inside a module the lowest Priority number wins
Fixed price and a percentage	The fixed price overrides the catalog adjustment	A Price List price replaces the Custom Pricing rule for that variant
Quantity breaks	Up to 10 per product. The price becomes fixed and the catalog adjustment stops applying	Volume Pricing takes its tier off the Price List or Custom Pricing price
Discount codes	Apply on top of catalog prices	Run after Volume Pricing and BOGO. Shopify automatic discounts do not work alongside Custom Pricing or Volume Pricing
Who can have it	Catalogs on all four plans, up to 3 active below Plus	Rules by tag, customer or company location

If your buyers fit into companies and three catalogs, native pricing is enough and there is nothing to rank. The rest of this guide is for the moment you add rules by tag and need to know who wins. For the native-versus-app decision, see Shopify native B2B.

Which pricing rule wins in BSS B2B Solution?

The app does not merge rules. It runs the modules in a fixed order, and each step starts from the price the step before produced (How Rule Priority Works).

1. Price List or Custom Pricing sets the base price. If a Price List rule applies to the product or variant, Custom Pricing is skipped for it.
2. Volume Pricing (quantity breaks) applies its tier to that base price.
3. BOGO starts from the Volume Pricing, Price List or Custom Pricing price.
4. Discount Code starts from the result of the steps above.
5. Extra Fee is a separate fee line. It does not change the product price.

Price list vs custom pricing: why the list wins

This is the point that surprises people. Priority does not decide between a Price List and Custom Pricing, because they are different modules. The list wins on every variant it covers, even if the Custom Pricing rule has priority 0 and the list has priority 50. The app checks the Price List first for each variant and only falls back to Custom Pricing when no list entry applies.

The practical risk runs the other way, and the user guide warns about it: a Price List rule with a higher price can stop a better Custom Pricing discount from applying. Give each customer group and product range to one of the two modules. Use lists for negotiated per-variant prices and Custom Pricing for broad percentage rules.

Volume pricing: tiers on the base price

Volume Pricing never starts from retail for a matched buyer. A $100 product with a Price List price of $80 and a 5% tier at 10 units costs $76 per unit. If the same buyer orders a product with no list entry, a 10% Custom Pricing rule makes it $90 and the tier takes it to $85.50 (Custom and Volume Pricing together). For a longer treatment see combine custom and volume pricing.

How does the Priority field work?

Rule editors have a Priority field in the Advanced card. The rules are simple, and each one removes a common mistake.

• Lower wins. Priority 0 beats priority 5. The field takes whole numbers from 0 to 99, and new rules start at 0. We checked that range in the code for Custom Pricing and Price List.
• Ties go to the older rule. If two rules share a number, the one created first applies.
• Only enabled rules compete. A disabled rule is ignored even at priority 0. A rule outside its schedule is ignored too.
• Only the same module competes. A Custom Pricing rule at 0 does not beat a Volume Pricing rule at 5. They combine.
• Leave gaps. Use 10, 20, 30 so you can slot a rule between without renumbering.

Module	Result
Custom Pricing	The lowest Priority number sets the price. The others are ignored
Price List	Same: one rule per product or variant
Volume Pricing	The lowest Priority number applies. A setting can show every matching table on the product page
Shipping Rate	No priority field. Settings decide between the lowest and the highest matching rate

We verified the 0 to 99 limit in code for Custom Pricing and Price List only. The guide describes the same field elsewhere, so check the field in the editor you use.

Worked example: three rules, two products

This is an illustration with made-up numbers, not a customer result. A buyer is tagged gold and wholesale, and orders 12 units of two products.

Rule	Module	Effect	Priority
Gold list	Price List	Product A fixed at $38 (retail $50)	3
Wholesale	Custom Pricing	15% off all products	10
Clearance	Custom Pricing	30% off all products	20
Case breaks	Volume Pricing	5% off from 12 units	5

• Product A (retail $50). The Gold list covers it, so the base price is $38 and both Custom Pricing rules are skipped. The tier takes 5% off $38: $36.10 per unit.
• Product B (retail $40). No list covers it, so the two Custom Pricing rules compete. Wholesale (10) beats Clearance (20), so the base price is $34.00. The deeper Clearance price of $28.00 never applies, because priority decides, not the size of the discount. The tier takes 5% off $34.00: $32.30 per unit.

If you wanted Clearance to win on Product B, give it a lower number than Wholesale, for example 5. Do not delete Wholesale: the next buyer who needs it would lose it.

How to set the order up step by step

Step 1: Decide which module owns which group

Write one line per buyer group: the module that sets its base price, and whether tiers apply. Gold distributors with negotiated prices go on a price list. A broad wholesale tag with a percentage goes on Custom Pricing (price by customer tag).

Step 2: Build rules and number them in the Advanced card

Open B2B pricing, pick the module and create the rule. In the Advanced card set Priority.

Step 3: Review the rule list

The Custom Pricing list shows the Priority column next to the target and the discount. Sort or scan it before you publish. Two rules at the same number that match the same buyer are the first thing to fix.

Step 4: Test as each buyer group

Log in as a test account with exactly the tags of one group. Open a product, a collection and the cart. Repeat for each group. Compare with a guest in a private window.

What to check when the wrong price shows

1. The BSS B2B Solution app embed is on in the live theme, and the module is on.
2. The rule is enabled and inside its schedule.
3. The buyer matches the customer condition (logged in, tag or company location) and the product is not excluded.
4. A Price List does not cover the same variant. If you expected Custom Pricing, this is the most common cause.
5. Two rules of the module share a number. The older rule wins. Make the order explicit.
6. The rule uses an option your plan does not include. It stays in the app but is not published.

A custom price also shows only when it is lower than the original price. For the wider list of causes read why Shopify B2B prices are not showing.

Limits to know before you rely on the order

Limit	What it means	What to do
Shopify automatic discounts	Do not work alongside Custom Pricing or Volume Pricing	Use Discount Code rules or manual codes. Manual codes need the Shopify Discount setting in Advanced Settings
Price List plan	Price List is a Platinum feature	Use Custom Pricing on lower plans
Price List is not a Shopify catalog	The app manages its own rules. It does not create Shopify catalogs	Do not expect a list to appear in Shopify’s Catalogs page
Express checkout	Express checkout and direct links can skip BOGO, Discount Code and Extra Fee	Test the checkout path buyers use
Headless	The app depends on the theme app embed	Treat headless storefronts as unsupported until you test them

Which module should you use?

Your situation	Use	Why
Negotiated price per variant for key accounts	Price List	Exact prices, and it overrules a general rule
One percentage for a whole buyer tag	Custom Pricing	One rule covers the catalog
Reward bigger orders	Volume Pricing	Tiers stack on the buyer’s own price
Up to 3 groups and companies only	Native catalogs	Nothing to rank, and no app fee
Many groups, retail and wholesale on one store	Rules by tag in BSS B2B Solution	Not capped at 3 catalogs
