Invoices → open an invoice → chat/comments panel
Open the invoice detail page.
Click the comment box labeled Add a comment.
Type your message. You can use multiple lines with Shift+Enter.
Press Enter or click the send button to post it.
If you change your mind, keep editing before sending; posted comments are saved in the invoice timeline.
Comments are limited in length; the send button disables when the text is empty or too long.
Type @ to open the mention menu.
Choose a person or team from the list.
Use arrow keys, Enter, or Tab to select a mention.
You can mention multiple people and teams in one comment.
If your invoice has approvers, you may also see a broadcast option for approvers.
The menu shows people, teams, and sometimes an approvers broadcast option in separate sections.
Stay on the invoice detail page to read the full comment timeline.
Refresh the page or wait for auto-refresh if new comments appear.
Comments are shown in creation order, oldest first.
Mentions are rendered from the saved mention snapshot so labels stay consistent over time.
Only comments are manually added; other timeline events like approvals and field updates appear automatically.
Type a few more letters after @.
Check that the person belongs to your organisation.
For teams, make sure the team has at least one member.
Try again after a moment if member search is still loading.
Make sure the message is not empty.
Shorten the message if it exceeds the comment limit.
Check that the invoice panel is still open and your session is active.
Retry after reloading the invoice page.
Delete the mention and re-add the correct person or team before sending.
Use the mention picker instead of typing a name freehand.
If the wrong user still appears, contact Cashfeed support.
Confirm the team exists in your organisation.
Confirm the team has at least one member.
Use a different team or mention individual people instead.
Contact Cashfeed support if the team exists but still does not appear.
