Init Invoice PDF Builder is a professional PDF invoice generator built for freelancers, sole traders, and small businesses. It handles discounts, VAT (inclusive or exclusive), multi-currency formatting, amount-in-words, and A4 PDF export — all directly in the browser, with no login, no backend, and no data sent to any server.
Overview
A professional invoice is more than a list of services and numbers. It signals transparency, helps clients understand the cost breakdown, and provides a paper trail if disputes arise. For freelancers and small businesses, a proper invoice is often a prerequisite for corporate clients to process payment through accounting, reclaim VAT input tax, or verify income for financial purposes.
Init Invoice PDF Builder simplifies the entire process. From seller and buyer details to line items, discounts, VAT, and amount in words — everything updates in real time on a live A4 preview, ready to export as PDF or print at any moment.
Key Features
- Live A4 Preview: The invoice preview updates instantly as you type — no save button, no page reload required.
- PDF Export: Export a high-quality A4 PDF directly from the browser, rendered correctly on both desktop and mobile.
- Multi-Currency: Supports 10 major currencies — VND, USD, EUR, GBP, JPY, SGD, KRW, CNY, THB, AUD — with locale-aware number formatting for each.
- VAT Inclusive / Exclusive: Choose whether your prices already include tax or not. Inclusive mode automatically back-calculates the VAT component for transparent display.
- Discount: Apply a percentage discount before tax is calculated.
- Amount in Words: Automatically converts the grand total to Vietnamese words (VND only).
- Company Logo: Upload a logo to display at the top of the invoice.
- Brand Color: Customize the accent color for table headers and key labels.
- Drag-and-Drop Reorder: Rearrange line items by dragging them directly in the form.
- Import / Export JSON: Save and reload full invoice data as JSON for reuse.
- Auto Save: Work is automatically saved to the browser — no data lost on page refresh.
- Print Support: Print the invoice directly from the browser with an A4-optimized layout.
VAT Modes
Init Invoice PDF Builder supports two tax modes to match real-world billing scenarios:
- VAT Exclusive: Use when your quoted prices do not include tax. The system adds VAT on top of the subtotal — the client bears the tax.
- VAT Inclusive: Use when your quoted price is all-in. The system back-calculates the VAT component and displays it separately for full transparency — you absorb the tax in this case.
Use Cases
- Freelancers: Send professional invoices to local and international clients after each project.
- Sole Traders: Issue invoices for goods or services to business partners.
- Agencies & Studios: Manage multi-line invoices across different service categories per project.
- Small Businesses: Generate multi-currency invoices for international clients.
- Internal Finance: Quickly create internal payment documents when needed.
