Most invite problems in the dashboard come from seat limits, unsupported role values, or CSV formatting. This guide uses the real Users and Billing flows in Blast Audit so you can fix the issue without guessing.

Who this is for

Workspace owners managing access in the dashboard
Admins sending single or bulk invites
Anyone blocked by seat limits or CSV validation messages

Before you begin

You may still see Copilot Audit in a few older labels.
Open the dashboard pages Users and Billing.
For seat changes, you need the Owner role.
Remember that pending invitations reduce available seats too.

How to do it

Check seat capacity in Billing.

In Seat management, review Seats purchased, Seats in use, and Active members.

If you need more seats, use Add seats.

If you are above the dashboard cap, the app shows Seat purchases are limited to 100 from the dashboard. Contact sales for larger orders.

Fix blocked seat reductions first.

If you see Lowering seats blocked, remove or disable the required number of users before reducing seats.

The dashboard explicitly says Disable or remove #{{count}} user(s) before lowering seats.

Use the safest path for single invites.

In User management, click Invite people, stay on Single invite, and complete Work email, Role, and Expiration (optional).

Supported roles are Member and Owner.

For bulk invites, start with Download template.

In Bulk upload, use the template instead of building your own CSV.

The bulk form expects columns labeled Email, Role, and Expiration date (optional).

Extra columns are ignored.

Fix the CSV headers if the file is rejected.

If the parser says Include the Email and Role columns in the header row., your header row is missing or renamed incorrectly.

Fix row-level CSV issues.

The dashboard can reject rows for these exact reasons:

Email is required.
Email format looks invalid.
Email can’t start with =, +, -, or @ for security reasons.
Role must be Member or Owner.
Expiration must be a valid date (use YYYY-MM-DD or your locale format).

Fix seat-overage errors before sending.

If the bulk sheet says Not enough seats, reduce the CSV to the valid headcount, cancel stale pending invites, or buy more seats.

The message will tell you how many people you selected versus how many seats remain.

Send again and review the summary.

A clean run ends with Invitation summary, plus counts for invites created, remaining seats, and any rows that still failed.

Expected result

Send invite or Send invites succeeds without validation errors
New invites appear under Pending invitations
Seat counts in Billing and Users stay aligned with the plan

Avoid this

Using roles other than Member or Owner
Renaming CSV headers instead of using the template
Uploading email cells copied from Excel formulas
Forgetting that pending invites consume available seat capacity
Trying to change billing as a non-owner

If it still doesn't work

Capture the exact validation message or the first few row errors
Note your available seat count before retrying
Test the same user with Single invite to separate CSV issues from seat or permission issues
If the dashboard still fails after a clean template upload, send a support escalation packet with the error text and a redacted CSV example
