Everything you need to create, send, and get paid for professional invoices with Simplified Invoice.

1. Sign up for a free account — no credit card needed.
2. Fill in your business details in Settings (used as defaults).
3. Create your first invoice — or a quote — from the sidebar.
4. Download it as a PDF, print it, or share a public accept link (quotes).
5. Record payments as they come in — full or partial — and the status flips itself.

• Quotes with numbered series (Q-YYYY-NNN), public accept links, and one-click convert to invoice.
• Partial payments with automatic status transitions (SENT → PARTIAL → PAID).
• Clean PDF export — with a Statement variant showing paid amount, balance, and payment history.
• Multi-currency line items and Fixed total (bundled projects).
• Save clients once — address auto-populates on new invoices.
• Show payment instructions for bank transfer, Mobile Money, PayPal, or crypto.
• Reports with aging, cash-flow trends, and top-clients breakdown.
• Bilingual EN / FR interface, dark mode, and mobile-first design.
