GST Billing & Invoice Integration on Your Website (India)
Indian ecommerce must issue proper GST invoices — CGST/SGST or IGST — with HSN codes and buyer GSTIN when B2B. Website checkout should connect to billing tools or ERP so invoices aren't manual afterthoughts.
Consult your CA for registration thresholds; tech integrates once compliance path is clear.
Whether you are fixing an existing site or planning a new build, these practices apply across WordPress, Next.js, and hybrid stacks. TechBisht ships them on low-budget landings from ₹1,000 through full-stack SaaS projects.
Small fixes (meta titles, broken links) are free wins you can do this week. Structural changes — new checkout, CRM wiring, migration off hacked WordPress — need a developer with written scope so timelines stay predictable.
What checkout should capture
| Field | B2C | B2B | | ----- | --- | --- | | Legal name | Yes | Yes | | GSTIN | Optional | Required | | State | For tax split | Required | | HSN on line items | In invoice gen | Required |
Integration options
Razorpay + Zoho Books, Tally bridge, or custom PDF generation from order API. Service businesses: invoice on milestone via same stack.
Budget expectations in India
| Scope | Starting from | Best for | | ----- | ------------- | -------- | | Manual invoice template | ₹0–₹2K | Very low volume | | Razorpay + accounting sync | ₹5K–₹15K setup | D2C under 100 orders/day | | ERP integration | ₹25K+ | B2B manufacturing |
Common mistakes to avoid
- Wrong tax type inter-state vs intra-state
- Missing HSN on products
- No invoice email automation
- Collecting GSTIN without validating format
When to DIY vs hire help
| Task | DIY-friendly | Hire a developer | | ---- | ------------ | ---------------- | | Blog posts & GBP updates | Yes | Optional | | SSL, DNS, canonical redirects | Risky alone | Recommended | | Razorpay + GST invoice wiring | Uncommon | Recommended | | New Next.js site from scratch | Rarely | Recommended |
Indian SMBs often start with a ₹1,000 landing page and reinvest once leads cover upgrades. Compare all plans before signing open-ended hourly contracts.
