Bulk Price Adjuster

Repricing hundreds or thousands of products by hand is error-prone and time-consuming. This tool lets you define a precise rule stack — percentage markups, fixed offsets, psychological rounding, floors, ceilings, and conditional overrides — and see the exact impact on every SKU before you commit.

Rule Types Explained

• Percentage — Multiply the current price by a factor. Use positive values to mark up (e.g. +10 = 10% increase) or negative values to discount (e.g. -15 = 15% off).
• Fixed Amount — Add or subtract a flat dollar amount from every price. Useful for covering a fixed surcharge or applying a blanket discount.
• Round To — Snap the cents portion of every price to a psychological price point (.99, .95, .49, or .00). Applied after other arithmetic rules to keep your catalog looking clean.
• Floor — Enforce a minimum price. Any calculated price below this value is raised to the floor. Protects your margins on cost-sensitive SKUs.
• Ceiling — Enforce a maximum price. Any calculated price above this value is capped at the ceiling. Useful for MAP (Minimum Advertised Price) compliance or competitive pricing ceilings.
• Conditional — Apply a rule only to rows where a specific column equals a specific value. For example, apply a 5% discount only to rows where “Category” equals “Clearance”.

Rule Stacking Order Matters

Rules execute from top to bottom. A +10% percentage rule followed by a .99 rounding rule will first increase the price, then snap the cents to .99. Reorder your rules by removing and re-adding them to change the execution sequence.
