Timeline actions
Comment and mention
Ease your account management with notes, or draw your teammates’ attention by mentioning them* to trigger a notification (email, slack, or only in-app).
*If the user you mention is a Member/Account manager, they must be assigned to the customer to access their timeline and your note. Otherwise, they won’t be available to be tagged.
Attach a file to your note
You can attach any files to the notes you leave on any timelines (Actions, Invoice details page, Customer details page).- Attachments can be added after the note is created.
- There is no file format limit.
- There is a limitation of 25 attachments to a note, and 15Mb global size limit.
- There is no preview of the attachment, but it’s downloadable from the note


Pin / unpin
Highlight essential information and make it easily accessible anytime by clicking on the pin next to any note (this doesn’t apply to other timeline events). It will add a pin logo next to your customer’s name and display the selected comments when hovered over. Undo it in the same way from the timeline or the pinned notes.
You can also add your pinned notes as a column from your Customers list view.Customers’ pinned notes are included in Customer exports.
- If there are several pinned notes for the same customer, they are added sequentially in the same field.
- All formatting is flattened, and attachments are not included in the export.
