Invoice Tracker & Client Manager | Freelance Billing Tool | Payment Tracking

Unpaid invoices hurt more than a missed deadline ever will. Stop losing track.

The Client & Invoice Tracker holds all your client information and invoices in one place. Add clients with contact details and status tracking (Active, Inactive, At-Risk). Create invoices with line items—describe the work, add the amount, watch the total calculate instantly. Every invoice gets a status: Outstanding (not paid yet), Paid, or Overdue (past due date). The tool shows you at a glance which invoices are waiting for payment and which clients are current. A client stat card dashboard gives you a quick view of your entire client base. Dark mode, light mode, whatever you prefer. Your data saves automatically and never leaves your device. No Google account. No Notion subscription. No app.

◈ YOUR DATA — HOW IT WORKS

Your client and invoice data live locally on your device using browser storage (localStorage). Nothing is sent to servers. Nothing is shared with banks or payment processors (unless you explicitly export). When you close the tool, your data stays on your device. When you open it next week, it's all there. Need a backup? Export your complete client and invoice database as a JSON file and keep it somewhere safe.

◈ WHO IS THIS FOR

→ Freelancers and contractors billing multiple clients → Small agency owners managing client relationships and invoicing → Solopreneurs who need to track payment status and follow up on outstanding invoices → Consultants with recurring client relationships → Anyone tired of spreadsheets for client and payment tracking

◈ IMPORTANT — PLEASE READ BEFORE PURCHASING

This is a digital HTML file—not accounting software, not an invoicing platform like Stripe Invoices or FreshBooks. You download it once and it lives on your device. Your client and invoice data are stored locally using browser storage (localStorage)—completely private, on your computer only. This tool is for tracking and organisation; it does not automatically send invoices or process payments. Always keep exported backups of your client and invoice data. If you clear your browser storage, data is lost—use the export function to back up regularly. There are no refunds on digital products. For technical help, contact us and we'll assist.
