+## Price Rounding
 
+Pricelist can be configured to round the final theoretical price (after taxes) to a fixed step:
+
+- **Sale Price Rounding Step**: Interval to round to (e.g. `0.05` rounds to the nearest 5 cents). Set to `0.00` to disable.
+- **Sale Price Rounding Method**: Direction applied when rounding:
+  - **Always up (ceil)**: rounds to the next multiple of the step *(default)*
+  - **Always down (floor)**: rounds to the previous multiple of the step
+  - **Nearest (round)**: rounds to the closest multiple of the step
+
+These settings are found on pricelist form under the **Sale Price Rounding** group.
 ## Price Calculation Types
 
 - **Without Discounts**: Uses base purchase price without discounts
