2 min read Stop Chasing Late Invoices Manually — Meet Invoice Chaser 🔥 Popular this week

If you run a freelance business, an agency, or any service business that sends invoices, you already know the drill: a client’s payment is late, and now you’re the one who has to remember to follow up, write the awkward email, and do it again a week later when they still haven’t paid. It’s tedious, it’s easy to forget, and it directly costs you cash flow.

Invoice Chaser fixes that — and we’ve just listed the full source code on the Megastore76 store.

What it does

Invoice Chaser is a working SaaS application, not a template or a mockup. Add your clients and invoices, and it automatically escalates reminder emails on your behalf:

• A friendly heads-up 3 days before the due date
• A polite nudge the day it’s due
• Firmer follow-ups at 3 and 7 days overdue
• A final notice at 14 days overdue

Every reminder is logged against the invoice, so you always have a clear paper trail of what was sent and when — and it never sends the same reminder twice.

What’s inside

• Full source code: Next.js, TypeScript, Tailwind CSS
• Prisma ORM data layer (SQLite for local dev, drop-in ready for Postgres)
• Secure email/password authentication
• Client and invoice management, with one-click “mark as paid”
• A dashboard showing outstanding balance, overdue totals, and reminder history per invoice
• Seed data included, so it looks alive the moment you run it
• A full README covering setup, running, and deployment

It’s built for developers and agencies who want to launch a focused invoicing tool without starting the reminder engine and data model from scratch.

Get it

Invoice Chaser is available now as a one-time source-code purchase: Invoice Chaser — Automated Payment Reminder SaaS (Source Code).

This is the first release in a series of focused, problem-solving tools we’re building and shipping — small, working products that solve one real, recurring pain point well, rather than trying to be everything to everyone. More to come.
