Step-by-Step Instructions

1. Navigate to the Customer Timeline

  • Go to the Customers section.

  • Open the Timeline of the customer you wish to contact.

  • Select the Reply option to open a new email draft.

2. Compose Your Email

  • Enter or confirm the recipient’s email address.

  • Add a subject line, for example: “Invoice Attached – [Company Name]”.

  • Write a short message, such as:

    Hello [Customer Name],
    Please find attached the invoice details for your reference.
    Thanks,
    [Your Name]

3. Attach the Invoice File

  • Click on the Attachment (paperclip) icon in the email editor.

  • Select the invoice file from your computer.

  • Confirm that the file is visible in the email draft (you will see the file name displayed under the message body).

4. Send the Email

  • Review the email content and confirm the attachment is correct.

  • Click Send.

  • Once sent, the email will appear in the customer’s timeline with an attachment record (e.g., Attachment: TEST-INVOICE-DETAILS.xlsx).


Verification in Outlook (Optional)

  • If you also view the email in Outlook, you will see the invoice file attached as expected.

  • This provides assurance that the customer will receive the attachment correctly.
