11. Core Mathematical Formulation & Financial Calculations

The studio applies industry-standard financial rounding algorithms to prevent fractional cent/paisa drift across line items, tiered discounts, and dual tax structures.

Formula / Standard Reference
Grand Total = (Gross Subtotal - Item Discounts - Global Discount) × (1 + Primary Tax% + Secondary Tax%) + Shipping Fee
  • Line Subtotal: Quantity × Unit Price with item-level fractional precision.
  • Tiered Discounts: Supports percentage-based deductions or fixed monetary amounts.
  • Dual Tax Handling: Independently computes primary (VAT / State Tax / CGST) and secondary (SGST / Federal) taxes.
  • Prepaid Deposit Deductions: Automatically calculates true net Balance Due for client settlement.

22. Scannable Payment QR Code Integration

Embeds dynamic client-side QR codes allowing clients to pay directly via mobile banking apps, UPI, SEPA IBAN transfer, or instant PayPal/Stripe payment links.

  • Instant Scanning: Eliminates manual account number transcription errors.
  • Universal Protocol Support: Compatible with standard UPI URIs, SEPA EPC QR codes, and web payment URLs.
