Overview
By default, ProLine rounds quantities up to the nearest whole number. Fractional Quantities let you override that rounding for specific price list items, so the calculated decimal value — rather than a rounded-up number — is what appears in quotes, invoices, and orders.
You enable fractional quantities item by item, not as a blanket setting across your price list.
Enabling Fractional Quantities for a Price List Item
Navigate to Company Settings > Price List.
Find the item you want to configure — for example, Underlayment.
Click the Price Default Calculation icon (first calculator icon from the left).
In the popup, under Rounding Behavior, click Whole Number. This toggles the option to switch to Fractional.
A confirmation message appears: "After switching, quantities for new Underlayment line items you add to quotes, invoices, and orders will be calculated and displayed as decimals. This change will only apply to new line items. Quantities for existing line items will not be updated."
Type SWITCH to confirm.
Click the blue Switch button.
Once enabled, this item will display decimal quantities whenever it is added to a new quote, invoice, or order.
Disabling Fractional Quantities for a Price List Item
Navigate to Company Settings > Price List.
Find the item configured for fractional quantities.
Click the Price Default Calculation icon.
In the popup, under Rounding Behavior, click Fractional. This toggles the option to switch back to Whole Number.
A confirmation popup appears.
Type SWITCH to confirm.
Click the blue Switch button.
The item will now round up to whole numbers for any new line items going forward.
How Fractional Quantities Work in Quotes
When a price list item with fractional quantities enabled is added to a quote, the system calculates and displays the precise decimal value based on your measurement data. This is most useful for materials where coverage calculations produce decimals — for example, if a measurement tool calculates that a job needs 2.1 rolls of underlayment, your team sees 2.1 on the quote — not 3. That gives them the accurate information they need to make better ordering decisions, like accounting for leftover material from a previous job.
Example: A project has 21 squares of total roof area. Underlayment has a default calculation of 1 roll per 10 squares. With fractional quantities enabled, the quote shows 2.1 rolls — not 3.
The total price is calculated on the exact decimal quantity (e.g., 2.1 × unit price)
The decimal value appears in the quote editor, preview, and signed PDF
Your team can see the real number and make informed decisions — for instance, if someone has leftover material on hand, they can factor that in before placing an order
How Fractional Quantities Work in Invoices
When you create an invoice or add line items to an invoice:
If the line item has fractional quantities enabled in the price list, decimal values are allowed
Invoice line items follow the same rules as quote line items (they use the price list configuration at the time of creation)
Decimal quantities display correctly in the invoice editor, preview, and PDF
Pricing is calculated based on the exact decimal quantity
How Fractional Quantities Work in Orders
Most suppliers cannot fulfill fractional orders — you can't call a supplier and request 2.1 rolls. For this reason, orders have a separate rounding control that's independent of the price list setting.
Note: Fractional quantities affect how calculated amounts are displayed — they don't change how materials are ordered or sold. For example, if a material is ordered in bundles, that preference is still set at the line item level. Fractional quantities simply give your team a more accurate picture of what the job actually requires.
Order Template Setting: Automatically Round Up Quantities
Go to Company Settings > Order Templates.
Open the order template you want to configure (click the pencil icon).
Click Order Details.
Scroll to Order Line Items.
Check or uncheck Automatically Round Up Quantities.
When enabled: All line items in orders using this template are rounded up to whole numbers — even if the price list item has fractional quantities enabled. This ensures your supplier always receives a clean, whole number quantity.
When disabled: Line items will use fractional quantities if the price list item has them enabled.
Recommended: Enable this setting on any order template used to send orders to vendors.
What this looks like in practice: A quote shows 2.1 rolls of underlayment (fractional quantities enabled). An order created from that quote using a template with rounding enabled will show 3 rolls — a number your supplier can actually fulfill.
Adding a New Price List Item Directly from an Order
If you add a brand-new item to your price list from within an order:
In the order, scroll to Add Line Item and type the new item name.
Enter the price, category, and unit of measure.
Check Use Fractional Quantities if applicable.
If the order template has Automatically Round Up Quantities enabled, a warning appears: "The new price list item will be added as fractional in the price list, but it will be rounded up to whole numbers in this order, as we're relying on the order template setting."
Click Add to proceed.
The item is saved as fractional in your price list for future use, but rounded to a whole number in this specific order.
Important: Existing Line Items Are Not Affected
When you change the fractional quantities setting for a price list item, only new line items are affected. Any line items already added to quotes, invoices, or orders will retain the rounding behavior from when they were originally created.
When to Use Fractional Quantities
Enable fractional quantities when:
Coverage calculations produce meaningful decimals and your team needs to see the precise amount
You want quotes to reflect exact material requirements rather than always rounding up
Rounding up every line item is creating noticeable discrepancies in your quotes over time
Stick with whole numbers when:
The item is only ever ordered in whole units
The decimal precision doesn't add meaningful information for your team
Your process doesn't benefit from showing customers decimal quantities
Best Practices
Enable fractional quantities only for items that genuinely require decimal precision.
Enable Automatically Round Up Quantities on any order template used to send orders to suppliers.
Test fractional quantity calculations on a sample quote before rolling out changes across your price list.
Communicate with your team — if they're used to seeing whole numbers, a decimal quantity may catch them off guard. A quick heads-up goes a long way.
Remember: changing the price list setting does not update existing line items. Only new line items will use the updated configuration.
Summary
Fractional Quantities let you display decimal values for specific price list items in quotes, invoices, and orders. Instead of always rounding up, your team sees the exact calculated amount — giving them accurate information to work from when building quotes and making ordering decisions. For orders going to suppliers, the Automatically Round Up Quantities setting on your order template ensures suppliers always receive whole number quantities, regardless of how the price list item is configured.
