Send the Invoice. Know It Arrived. See It Paid.
MailerBit sends your clients their invoices, payment reminders, statements and notices — each with their own amounts and attachments, from your own domain. Every email lands on the client's card with its delivery status, every payment is tracked until it's paid, and optional automatic reminders follow up for you. Built for accounting offices, language schools, kindergartens and property managers.
What Is MailerBit?
MailerBit is a client communication tool for the emails you send to the people you already work with — clients, parents, tenants. Keep your clients in one place, send each of them their own email with their own data (amount due, account number, their own invoice PDF), and see on the client's card everything that happened: what was sent, delivered and opened, and which payments are open, overdue or paid. Schedule recurring sends monthly or weekly, track the payments they are about, and let optional automatic reminders follow up until a payment is marked paid. Emails go out from your own verified domain, with one-click unsubscribe and automatic bounce handling.
Sending the Invoice Is Not the End. Now You See It Through.
Until now you knew the email went out. Now MailerBit shows what happened next — for every client and every payment.
Clients and their full history
One card per client: company details, notes, the groups they belong to and a timeline of every email — sent, delivered, opened, bounced — and every payment.
Payments attached to emails
Send an invoice with the PDF attached, assign a payment to an email you already sent, or let your monthly send create a payment for every client automatically.
Paid, partially paid, overdue
Mark payments as paid in one click or in bulk, record partial payments, and see what's left to collect and what's overdue — per currency, with ageing.
Reminders that stop when it's paid
Optional automatic reminders before and after the due date, at the hour you choose. They stop the moment you mark a payment paid and never go to clients who unsubscribed.
MailerBit doesn't issue invoices or take payments — you keep your invoicing software and your bank. MailerBit delivers, tracks and follows up.
