Send your invoices, quotes, packing notes and payment reminders from your own Gmail or Google Workspace address. Customers see your own domain, and replies land in your own Gmail inbox.
There is no SMTP host, port or app password to look up. You sign in to your Google account once from Invoice Office, and Invoice Office then sends through it on your behalf.
Before you start
- You need the Modify right on Setting to open the Email server page.
- Connecting a mail server needs a paid licence (Basic or higher). Without one, the page is locked and the Connect button is greyed out.
- Have the login of the Google Workspace or Gmail account you want to send from ready.
Step 1 — Choose Gmail / Google Workspace as your provider
- Go to Settings → Email server. It sits in the Email group, under E-mail sender.
- Switch Enabled on.
- Set Mail server provider to Gmail / Google Workspace. The choice is saved straight away and the page reloads with an Authorize row in place of the SMTP fields.
Step 2 — Connect your Google account
- Click Connect on the Authorize row.
- Google’s sign-in page opens. Sign in with the Google Workspace or Gmail account you want to send from.
- Allow the access Google asks for. It lets Invoice Office send email from your account.
- You are taken back to the Email server page. The button now reads Disconnect, and the connected account shows under it as Email address.
That connected address is the one your documents are sent from.
Step 3 — Save, then log out and back in
- Click Save.
- Log out and log back in. The page says so itself: a new mail server configuration only takes effect on your next session.
From then on, the documents you email from Invoice Office go out through your own Google Workspace or Gmail account.
Disconnect or switch accounts
To stop sending through Google, or to use a different Google account, go back to Settings → Email server and click Disconnect. Invoice Office revokes its access to your Google account and removes the stored address. Click Connect again to sign in with another account.
Troubleshooting
- “Gmail account is not connected” when you send a document. Gmail / Google Workspace is selected as the provider, but no account is connected. Open Settings → Email server and click Connect.
- Nothing changed after connecting. Log out and back in. The new configuration only applies to your next session.
Prefer to enter SMTP settings yourself?
You can also send through Google’s SMTP server by choosing Custom as the provider instead. Google then expects an app password rather than your normal password, and app passwords only exist once 2-Step Verification is on for the account. Google explains how to create one in Sign in with app passwords. The custom setup itself is in Configure a custom SMTP email server.
Not on Google Workspace?
The same Mail server provider list has two other options:
- Outlook / Office 365: see Configure Outlook / Office 365 for email.
- Custom: any other SMTP server, see Configure a custom SMTP email server.
