Overview
Time and materials (T&M) invoices let you bill your customer based on the actual time and materials your crew uses on a job. Use this article to generate a T&M invoice, review the line item details, and make any needed adjustments before you deliver it to your customer. Watch the video below or keep reading to learn more.

Things to know
T&M invoices are the only invoice type where you should adjust revenue directly on the invoice after the work ticket is complete. For all other invoice types, handle changes through change orders.
There are two types of T&M invoicing:
Contract T&M — Services are available to invoice as each work ticket is completed.
T&M on completion — The invoice is available only after all tickets on the opportunity are complete.
Changes to a pending T&M invoice update the overall price only. They don't update costs on the work ticket and don't affect job costing.
If a team member applied a T&M override during the work ticket approval process, the invoice total won't update automatically when you adjust quantities or rates. You'll need to update the total manually.
Requirements
You need the following permissions to generate and edit T&M invoices. If you don't have these permissions, contact your administrator.
To access to the Invoicing Assistant, Invoice Batches, and Invoices tabs in the Invoicing module, you need View Invoice added to your user role.
To access Bulk Actions in the Invoicing Assistant to generate invoices, you need Create Invoice added to your user role. This permission must be explicitly added, even for System and Branch Administrators.
To modify values on a pending invoice and complete batches, you need Edit Invoice added to your user role.
For more information on permissions, visit Defining Role Permissions in Aspire.
Steps
Generate a T&M invoice

Review and edit the invoice
While in Draft status, you can review and adjust the details before completing the batch.
Select the batch to open the detail view.
To adjust a line item, update the Quantity, Description, or Unit Price fields as needed.
Note:
Your Quantities reflect what your crew allocated to the work ticket, and unit prices come from your opportunity setup.
To remove an item added in error (for example, an inventory item that was allocated by mistake and wasn't used on the job), select the trash can icon next to the item.
To add a missing item (for example, fertilizer that wasn't allocated during the job), select the plus icon to add a new line item.
Enter the quantity.
Select the item type from the menu.
Enter a description of the item.
Enter the unit price.
Select Save.
Note:
If the total doesn't update after you adjust quantities or rates, a T&M override was applied during ticket approval. Update the total manually to match the line items.

Complete the batch
After you've reviewed all invoices in the batch, complete the batch to deliver the invoices to your customer.
From the pending batch view, confirm that all invoices are accurate.
Select Complete to finish the batch and deliver the invoices.
What happens next
After you complete the batch, your invoices are delivered to your customer. Revenue changes you made on T&M invoices reflect in reports such as Profit and Loss and end of month (EOM) reports.
