Why Not a SaaS Tool?

Haznox Invoice vs. SaaS Alternatives

Most invoicing tools charge monthly fees, show their own branding, and keep your data on their servers. Haznox Invoice is different in every way that matters.

Common Questions

Frequently Asked Questions

Is Haznox Invoice really completely free?⌄
Yes — 100% free for all active Haznox Hosting clients. No monthly subscription, no per-invoice charge, no premium tier. The only requirement is an active hosting plan with Haznox. As long as your hosting is active, the invoice app is yours at no extra cost.
Does it support GST and inventory tracking?⌄
Yes — both are built into the core. For GST: assign HSN codes per item, switch between GST-inclusive and exclusive modes, store GSTIN for your company and customers, and get a full GST breakdown on every PDF and monthly report. For inventory: each product has a live stock quantity field that lets you track your available stock and link products directly to invoices.
How does sending invoices by email work?⌄
From any invoice, simply click the email button. The app generates the PDF and sends a professional HTML email to the customer's email address with the invoice attached — all in one click. You can configure your SMTP settings (Gmail, cPanel, etc.) from the settings panel, and every sent email is logged so you can track delivery.
Will my customers see "Haznox" branding on the invoices?⌄
Never. Haznox Invoice is fully white-labeled. Your company name, your logo, your GSTIN, and your contact details appear on every invoice and quotation PDF. There is no "Powered by Haznox" footer, no watermark, and no mention of us anywhere your customers will see.
How do automated payment reminders work?⌄
You configure which days to send reminders (e.g., 5 days before due, 2 days after due) and at what hour (IST). The system uses a cron job on your server to automatically send HTML reminder emails to customers with unpaid invoices. You can enable/disable it at any time from Settings and send a test email to verify your setup.
What URL will my invoice app be on?⌄
You choose. Common setups are a subdomain like invoice.yourdomain.com or a subdirectory like yourdomain.com/invoice. We configure and deploy it to your preferred URL as part of the free setup — just let us know your preference when you sign up for hosting.
Where is my data stored?⌄
Your data lives entirely on your own Haznox hosting account — in your own database, on your own server. We do not have access to your business data, customer records, or financial information. Your data is never shared with third parties.
What happens if I cancel my Haznox Hosting plan?⌄
The invoice app runs on your hosting account, so cancelling hosting would take it offline with your website. However, your data is always yours — you can export invoices as JSON at any time, and we can assist with migrating the app to another host if needed.
