Fauran Invoice Manager

Description

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

1. Set up your catalog — categories and services, each with its own price and optional variants.
2. Create an invoice (standard or custom), picking catalog items or entering custom line items, with tax, discount, and partial-payment support.
3. 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.
4. 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.
5. 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
