Invoice Reminder sends automatic SMS and email follow-ups from your Android phone — before the due date, on the day, and when an invoice goes overdue. You create the invoice, it does the chasing.
Follow-ups are awkward, easy to forget, and overdue invoices quietly kill your cash flow.
Clients don't chase invoices — invoices get chased. Without a reminder, "I'll pay next week" becomes next month.
You know you should follow up, but every "just checking in…" email feels awkward — so it never gets sent.
Studies show late invoices are far less likely to be paid. A friendly, automatic reminder at the right moment changes everything.
Built for freelancers and small businesses that want professional follow-ups without the admin.
Sent from your own phone number — before the due date, on the due date, and again when an invoice goes overdue. The schedule is yours to control.
Branded, professional HTML invoices by email. Tap a button on any invoice and a polished reminder goes out through your own SMTP account.
A red badge shows how many invoices are overdue at a glance. The dashboard tells you exactly who owes what — and reminds them for you.
Everything lives in a private on-device database. Auto invoice numbers, status tracking and dashboard stats — no cloud, no data sharing.
Register your phone with your license server and it stays licensed — with a free trial, monthly or yearly plans. Unregistered devices stay locked.
The app checks for new versions automatically and installs them in a tap. You always run the latest build — no store required.
Create invoices in seconds with auto numbering. The app tracks status, due dates and overdue flags.
SMS reminders go out before the due date, on the due date, and after — on a schedule you control from the server.
Clients pay, you mark it paid, and the dashboard celebrates. Professional follow-ups, zero awkward conversations.
Every invoice follows a smart, configurable cadence — no more guessing when to follow up.

Cash FlowGetting paid isn't about luck. These five habits keep cash flowing even when clients are slow.
ProductYour phone is already with you everywhere — so why is your invoicing stuck at your desk? Run your follow-ups on-device.
