Billow is a focused GST sales invoicing app built for Indian B2B businesses that want to create legally correct invoices without using complex accounting software.
Most GST tools in India are built for accountants first.
Billow is built for business owners who handle billing themselves.
What Billow solves:
Creating GST-compliant B2B sales invoices without accounting setup
Reducing fear around GST mistakes
Saving time on repetitive billing work
Producing clean, CA-friendly invoices that are easy to share or export
Who Billow is for:

Job-work and fabrication businesses
Transporters and logistics vendors
Low-SKU suppliers and traders
Businesses where invoices have few line items and are owner-managed
Who Billow is NOT for:
Retail / POS billing
Inventory or stock management
Purchase accounting
GST return filing or ERP workflows
How Billow is different:
Does one job only: GST sales invoices
Does not replace Tally, Busy, MCS or Zoho
Designed to work alongside your CA, not replace them
Intentionally limited to stay simple, safe, and audit-friendly
Technical details (for builders):
UI: Next.js + shadcn/ui + Tailwind CSS

Database: Stores businesses, customers, products, and invoices
Deployment: Vercel
Product philosophy:
No ledgers
