Bulk price increase on Shopify

Price increases are less dramatic than sales and more consequential: they are permanent, they affect margin on every future order, and getting them slightly wrong across a catalog is hard to notice.

Doing them as one filtered task with a rounding rule keeps the catalog coherent, which matters more than it sounds when customers compare products side by side.

Ways to express an increase

• Increase by percentage — the usual response to a supplier increase.
• Increase by amount — for a flat surcharge such as packaging.
• Adjust based on cost per item — restate the price from the new cost and a target margin.
• Round to — pull every result back to your standard ending.
• Update cost per item in the same task so margin reporting stays truthful.

Scoping the increase

• By vendor — increases arrive supplier by supplier.
• By product type — when a materials cost moves.
• By price band — apply different rules to cheap and expensive items.
• By tag — to exclude contract-priced or promotional lines.
• By update date — to catch anything missed in a previous round.

A worked example: 6% on one supplier, cost included

1. Filter: vendor is “Northwind”.
2. Editor: cost per item → increase by 6%, round to 2 decimals.
3. Editor: price → adjust based on cost per item, increase by 130%, round to .95.
4. Check the calculation example on a sample product.
5. Run it, then spot-check three products in the admin against the supplier’s new price list.

Increases and compare-at price

If products carry a compare-at price left over from an old promotion, raising the price can leave the reference price below the live price, which looks broken in most themes. Clear stale compare-at values before a general increase.

A price increase is a good moment to run the catalog hygiene tasks you have been postponing: rounding, missing costs, orphaned reference prices.
