Precision (Decimal Settings)

Overview

Precision in CustomBooks™ refers to the number of decimal places used in system fields such as:
  1. Quantity
  2. Price
  3. Cost
This setting determines how many digits appear after the decimal point and directly affects how values are entered, calculated, and displayed across transactions.

Precision is essential for businesses that require accurate measurements, fractional quantities, or detailed cost calculations.

What is Precision?

Precision defines the level of detail used in numeric values.

For example:
  1. A precision of 2 decimals → 10.25
  2. A precision of 4 decimals → 10.2575
The higher the precision, the more exact the value becomes.

In accounting and inventory systems, decimal precision impacts both:
  1. Data entry and display
  2. Calculation accuracy and rounding behavior

Precision in CustomBooks™

In CustomBooks™, precision applies to the following key fields and can be configured up to a maximum of 4 decimal places:

Quantity Precision
  1. Determines how many decimal places can be used when entering item quantities
  2. Useful for businesses dealing with:
    1. Partial units (e.g., weight, volume)
    2. Bulk or fractional inventory
Example:
  1. Precision = 2 → 1.25 units
  2. Precision = 4 → 1.2575 units

Price Precision
  1. Controls the number of decimal places for the item selling price
  2. Ensures accurate pricing, especially for:
    1. High-volume, low-cost items
    2. Items priced in fractions

Cost Precision
  1. Defines decimal places for item cost values
  2. Supports accurate cost tracking and margin calculations

Setting Up Precision

  1. Navigate to Admin Panel → General Settings.
  2. Look for Precision.
  3. Change the number of decimal places to the maximum you will need to use on the quantity, price, and cost field decimals. Changes made are auto-saved by the system.
Warning
Please note that once a higher precision is set, it cannot be reduced. For example, if the precision is increased from 2 to 3 decimal places, it cannot be reverted to 2 after entering transactions.



How Precision Affects Calculations

Precision plays a critical role in how totals are computed:
  1. System calculations typically follow:
    Quantity × Price = Line Total
  2. More decimal places allow for more accurate intermediate values
  3. Final totals may still be rounded based on system rules
Using higher precision helps reduce rounding discrepancies, especially in large-volume transactions or fractional quantities.

Why Precision Matters

  1. Improved Accuracy - Higher precision ensures that even small value differences are captured correctly.
  2. Better Cost and Margin Control - Accurate cost and price decimals lead to more reliable profit calculations.
  3. Flexibility for Different Industries - Supports industries that require:
    1. Fractional quantities (e.g., manufacturing, distribution)
    2. Detailed pricing structures
  4. Reduced Rounding Errors - Minimizes discrepancies caused by repeated rounding during calculations.

Best Practices

To effectively use Precision in CustomBooks™:
  1. Use higher precision (up to 4 decimals) for:
    1. Inventory items with fractional quantities
    2. Items with very small unit costs
  2. Use standard precision (e.g., 2 decimals) for:
    1. Simpler transactions
    2. Currency display consistency
  3. Regularly review precision settings to ensure they align with your business needs

Summary

Precision in CustomBooks™ controls the number of decimal places used in quantity, price, and cost fields, with support for up to 4 decimal places. Proper configuration ensures accurate data entry, reliable calculations, and consistent financial reporting.
