PayChaser — Invoice Follow-Up Workspace Source Code

Keep invoice follow-ups from slipping

Late invoices are easy to lose track of, and writing a follow-up can feel awkward. PayChaser gives independent businesses one focused place to see what is due, decide what needs attention, and prepare a clear message.

Add an invoice, keep its due date and payment status visible, and use the overdue queue to decide what to follow up on. Choose from three editable message tones, review the wording, copy it into your own email app, and record that you sent it. Mark payments manually when they arrive. There is no automatic client contact or payment processing.

Features

• Dashboard for outstanding, overdue, paid, and recorded follow-up totals.
• Create and edit invoices with client, optional email, dates, amount, and a short description.
• Search invoices and filter by open, overdue, or paid status.
• Client directory derived from invoice records.
• Three editable payment reminder drafts: friendly, clear and direct, and final check-in.
• Copy a reviewed reminder and manually record a sent follow-up.
• Manually mark invoices paid or unpaid.
• Export invoices to CSV and download or restore a JSON backup.
• Currency and workspace preferences; responsive English interface.
• Plain HTML, CSS, and browser JavaScript; no runtime dependencies.

Included

The source project, run/setup notes, an illustrative sample workspace, and an editable promotional cover graphic. Open index.html in a current browser; no server or API key is needed to try the included build.

Honest scope

This is a functional local-first source-code starter, not a hosted SaaS. The current build does not send email or SMS, process payments, generate invoice PDFs, connect to accounting or banking providers, sync between devices, provide user accounts/team access, or send automatic reminders. Statuses and follow-up activity are entered manually. The app stores data in browser local storage, which is not encrypted by this app. Sample names, emails, and amounts are fictional.

The US$99 offer is intended as a non-exclusive commercial source-code license. The seller retains copyright. No hosted service, domain, buyer data, exclusivity, ongoing support, updates, or warranty is included. The final marketplace license and terms control.
