How to Safely Bulk Edit Shopify Prices — and Undo If You Get It Wrong

Pricing changes are the scariest bulk edit there is. A typo in a percentage or an absolute value does not affect one product — it affects every product in scope, instantly, on your live store. So the two things that matter most when repricing in bulk are a real preview before you commit and a fast way to undo after.

Describe the price change

With Lasso you say what you want rather than building a formula in a spreadsheet:

• “Raise all prices by 10%”
• “Set everything in the Clearance collection to $19.99”
• “Round all prices up to the nearest .99”
• “Start a 25% off sale on all snowboards with compare-at prices”

Scope it to a collection, a tag, a vendor, a product type, or your whole catalog. Lasso resolves the matching variants server-side, so you never select products by hand.

Preview every new price

Before anything ships you get a staged change per variant showing the old price next to the new one — and the compare-at price too when you are running a sale. Spot a rounding edge case or a product that should be excluded? Edit or drop that single row. The rest still applies.

Run a sale the right way

A proper sale shows the original price struck through. Lasso handles the ordering for you: it copies the current price into the compare-at field first, then discounts the price — so the strike-through is correct. To end the sale later, clear the compare-at price in one instruction.

Undo in one click

Every apply snapshots the previous prices. If a sale ends early, or a percentage was wrong, you do not reconstruct anything from a backup — you click undo and the entire batch reverts to exactly what it was. For very large repricing jobs Lasso also writes a downloadable pre-apply backup of the old prices.

The takeaway

Bulk repricing does not have to be a leap of faith. Preview the exact new prices, apply only when the diff looks right, and keep one-click undo ready. That is the difference between a confident afternoon of merchandising and a stressful one.
