How to create and send an sale invoice?

Left Navigation Bar > Sales > Invoices

Follow the steps below to create a sales invoice :

Click on "Sales."
Then, click on "Invoices."
Select the client.
As soon as a client is selected, the relevant client details will be automatically filled in the corresponding fields.
If you wish to add a new client, click on "Add a new client" from the client dropdown list.
If you want to link time entries, enable the Timesheet toggle.
1. You can then use the selectors to switch between clients with pending time entries.
2. Period selectors will appear—choose the relevant dates to modify them.
In the Invoice Details section, choose the appropriate Sales Category from the dropdown.
Select "VAT Included" if you want VAT to be deducted from the unit price.
Enter the details of each item or service.
To add a new line, click "+ Add a service or product."
You can organize your products by adding sections and rearranging them as needed.
To customize fields, time entries, invoice format, or language, click on "Settings."
Check the box to bill time entries but change the quantity shown to the client.
Enable the option to customize categories per line.
Enter an adjustment value in the "Adjustment" field to round totals.
You can also apply a discount (as a percentage or fixed amount) to the invoice total.
Enter comments in the comment box, or add custom text above or below the invoice table.
To preview the invoice, click on "Preview" in the top-right corner.

In the invoice preview, you will see the text "Payment method" appear. This text is not editable and indicates the account to which users can make payment via bank transfer. This account is the one you select when creating the invoice, which can be either with an IBAN or an IBAN QR.
To generate and send the invoice, click on "Generate and Send".
Clicking the arrow next to this button opens more options.

Generate and send: the invoice will be finalized and sent to the client by email in a single step.
Generate without sending: the invoice will be generated but not sent immediately.
Generate and download: the invoice will be generated and downloaded for printing or archiving.
Generate, send, and finalize: the invoice will be generated, sent to the client, and the process will be completed.
Save as draft: the invoice will be kept as a draft, without being finalized or sent.

Sending via Email and Client Portal :

Click "Generate and Send."
You’ll see a preview of the email that will be sent to your client.
You can edit the message if needed.
Check the email address in the "Send to" field.
If the client is connected, the email will include a link to the client portal.
Click "Confirm" to send.

The invoice will now appear in your invoice list, and the client will receive it by email and in their Sequence portal (if connected).
