Manager only sends email through SMTP settings you type in (server, username, password), with no Microsoft sign-in, and Microsoft is turning off password-based SMTP for Microsoft 365 by default at the end of 2026. We send them from your Outlook or Microsoft 365 mailbox, so customers see your name and your invoices stay out of spam.
Customers see invoices from you@yourcompany.com, sent through your own Outlook, and replies come straight back to you.
Stop the "check your junk folder" calls. Many companies filter shared invoicing senders because scammers imitate them.
An invoice from a name customers recognize gets opened and paid, and Manager.io still tracks it as sent.
One secure click. We only use the invoices you send.
Sign in with your Microsoft account. No passwords stored, no IT project.
We send them from your Outlook automatically, PDF attached, and mark them sent in Manager.io. They show up in your Sent Items too.
