VyaparStack was engineered to provide Indian freelancers, consultants, and agencies with an institutional-grade billing engine that guarantees 100% statutory compliance without administrative overhead.
You never have to calculate whether a client requires 9% + 9% CGST/SGST or 18% IGST. VyaparStack inspects the supplier state prefix against the recipient state prefix, automatically routing tax components and rendering compliance ledgers per CGST Rule 46.
Most legacy billing software relies on headless Chromium instances or Node.js disk writes that crash serverless functions. VyaparStack generates vector PDFs purely in-memory via pdf-lib and streams them directly as Uint8Array buffers, ensuring instant cold starts and zero server disk leaks.
At the end of each filing period, solopreneurs can export a verified JSON payload conforming directly to Table 4A (B2B) and Table 7 (B2C) schemas. Hand off the file to your Chartered Accountant or upload directly to the GST offline tool with zero manual data entry.
