About
In the gig economy and small business administration, the boundary between a formal invoice and a point-of-sale receipt is often blurred. However, accuracy in financial documentation is binary: TRUE or FALSE. This tool bridges the gap, allowing contractors, landlords, and service providers to generate high-fidelity transaction records without enterprise POS hardware.
Unlike standard text editors, this system utilizes a WYSIWYG (What You See Is What You Get) engine that renders digital output mimicking physical thermal paper. It calculates totals using standard accounting precision, handling variables like Subtotal, TaxRate, and GrandTotal automatically.
Crucially, this architecture runs entirely client-side. Your signatures and logos are processed via the browser's Canvas API and never transmitted to a server, ensuring 100% data privacy.
Formulas
The core logic follows standard ledger arithmetic. The tax amount T is derived from the Subtotal S and the Tax Rate r (expressed as a decimal, e.g., 0.20 for 20%).
1. Basic Calculation (Exclusive Tax):
Total = n∑i=1 (pi × qi) × (1 + r)
2. Reverse Calculation (Inclusive Tax):
If tax is included, the base price S is:
Total1 + rWhere p is price per unit and q is quantity.
