Fauran Invoice Manager

Fauran Invoice Manager helps small businesses manage their day-to-day billing operations directly from wp-admin, with a modular architecture and dynamic branding that adapts to your company details:

• Categories and services catalog — organize services under categories, with per-service pricing and variants

• Invoices — create standard and custom invoices, with tax, discount, and partial-payment support

• Customer management — customer records are created or matched automatically from invoice data, with running stats (total invoices, total spend, balance due)

• Reminders and follow-ups — schedule a follow-up date per invoice; a dedicated Follow-ups screen surfaces what’s due

• Price snapshots — past invoices always show the price that was charged at the time, even if a service’s catalog price changes later

• PDF export and printing — print-friendly invoice/receipt templates and PDF generation for invoices and reports

• WhatsApp messaging — send reminder, follow-up, and invoice messages to customers directly via WhatsApp

• Reports — payment and balance-due reporting, exportable to PDF

• CSV import/export — bulk import customers from CSV, export customer data back out

• Dynamic branding — company name, logo, address, and footer text flow through to invoices, receipts, and PDFs

• Extensible — a set of action/filter hooks lets developers customize behavior without editing core files (see “For Developers” below)

Why This Plugin

Most invoicing plugins either lock core billing features behind a paywall or bring more complexity than a small business actually needs. Fauran Invoice Manager focuses on the day-to-day essentials — catalog, invoices, customers, reminders, and reports — in one modular, self-contained plugin:

• No external SaaS account or API key required to create and print invoices

• Dynamic branding means it looks like your business, not a generic template

• Price snapshots protect the accuracy of past invoices when catalog prices change

• Action/filter hooks let developers extend it without touching core files

How It Works

• Set up your catalog — categories and services, each with its own price and optional variants.

• Create an invoice (standard or custom), picking catalog items or entering custom line items, with tax, discount, and partial-payment support.

• The plugin automatically creates or matches a customer record from the invoice’s contact details and keeps running stats (total invoices, total spend, balance due) up to date.

• Optionally set a follow-up date on the invoice; it will surface on the Follow-ups screen, and reminders can be sent to the customer via WhatsApp.

• Print or export the invoice as a PDF, and track payment/balance-due activity from the Reports screen.

Requirements

• WordPress 6.6 or later (tested up to 7.0)

• PHP 7.4 or later

• MySQL/MariaDB with permission to create custom tables (the plugin creates its own tables for invoices, customers, services, categories, payments, and reminders on activation)

• No third-party API keys or paid services required for core functionality
