Invoice Rejected: Billing Period Line Item Mismatch

Short Answer

This rejection means that one or more line item work dates on your invoice fall outside the billing period you entered in Brightflag during submission.

What This Means

When you upload a PDF invoice in Brightflag, you are asked to enter:

• Billing Period Start Date

• Billing Period End Date

Brightflag compares the billing period you enter during submission with the individual work dates listed on each line item in the invoice breakdown.

If any line item date falls outside the billing period you entered, the invoice may be automatically rejected (if your client has this rule enabled).

This check is based on the line item dates, not the billing period printed on the invoice cover page.

Example

If you enter the following billing period in Brightflag:

August 1, 2025 – August 31, 2025

Then every line item on the invoice must show a work date between:

August 1 and August 31, 2025

If even one line item shows:

• July 31, 2025

• September 1, 2025

the invoice may be rejected.

Common Causes

This rejection usually happens because:

• A single line item has a date outside the selected billing period

• Line items do not clearly show individual work dates

What To Do Next

1. If needed, adjust the billing period or revise the invoice so all dates align.

2. Reupload and resubmit the corrected invoice.

3. Confirm that each work date falls within the selected billing period you enter in Brightflag. 

Important Notes

• This is a client-configured automatic rule.

• Brightflag cannot override this rejection.
