# Price Dependency
Price Dependency defines formulas that derive one item's selling price from another item's price. Rules are applied on the Date Wise Pricing screen using Calculate Dependencies — they do not resolve prices directly on sale bill entry.
Overview & List View
Go to Sales → Settings → Price Dependency from the left menu.
Create rules when the price of one item should automatically follow another item's price — for example, a finished good priced as raw material plus a markup.

Fields
| **Field** | **Description** |
|-----------|-----------------|
| Item * | The item whose price will be calculated. |
| Source Item * | The item whose current price (x in the formula) is used as input. |
| Formula * | Expression evaluated against the source item price. Use x for the source price. Example: x+10, x*1.05. |
| Round to | Optional rounding after formula evaluation: nearest 10, floor to 10, ceiling to 10, nearest 1, floor to 1, ceiling to 1. |
How It Works
- Define dependency rules on this screen — one rule per target item.
- On Date Wise Pricing, set or load prices for source items on the selected date.
- Click Calculate Dependencies. For each rule, the system reads the source item's price in the grid, evaluates the formula, applies rounding, and writes the result to the target item's price.
- Click Update Price on Date Wise Pricing to save the computed prices.
On sale bill entry, prices from Date Wise Pricing (including dependency-calculated values) apply in the resolution chain after previous customer price and pricing rules. See Sale Settings → Price.

FAQ
Is Price Dependency the same as Date Wise Pricing?
No. Date Wise Pricing stores prices by date. Price Dependency only defines how one item's price is calculated from another — the calculation runs on the Date Wise Pricing screen.
What variable can I use in the formula?
Use x for the source item's current price in the Date Wise Pricing grid.
What happens if the source item has no price?
The formula cannot compute a valid result for that dependency until the source item price is set.
Where is the formula evaluated?
On the Date Wise Pricing screen when you save or refresh prices for the effective date — not on the sale bill directly.
Can one source item drive many dependent items?
Yes. Define multiple dependency rows pointing to the same source SKU with different formulas (e.g. pack sizes).
Do I still need basic pricing for dependent items?
Dependent items typically rely on the computed date-wise price. Keep basic pricing as fallback if the formula cannot run.
What happens when the source price changes?
Re-save or recalculate date-wise pricing for the affected date so dependent item prices update before new sales are entered.
