Seedha jawab: Wholesale b2b e invoice compliance matlab applicable turnover cross karne par har B2B tax invoice pe Invoice Reference Number (IRN) GST IRP se generate — QR code print, buyer ITC match, GSTR-1 auto-populate. Distributor 50+ B2B bills daily — manual portal impossible; billing software integration mandatory.
2026 me threshold gradually chhote businesses tak — wholesale distributor almost certainly covered agar turnover ₹5 crore+ (verify latest notification). B2B 90%+ business = har din IRN workflow. Fail = buyer cannot match ITC, aap notices risk.
E-invoice vs normal invoice
Normal invoice: aap number assign, print. E-invoice: JSON portal ko bhejo → IRN + signed QR wapas → print with IRN. Invoice without valid IRN (when mandatory) = not compliant B2B supply document.
Who must e-invoice — distributor check
- Aggregate turnover threshold — annual review
- B2B taxable supplies primarily — distributor fit
- SEZ, export — different rules
- B2C retail counter — usually no IRN per bill (B2B wholesale different)
CA confirm applicability; software enable IRN when yes.
IRN generation workflow
| Step | Action | Failure mode |
|---|---|---|
| 1 | Create sale invoice — all fields valid | Invalid GSTIN, HSN |
| 2 | Software sends to IRP API | Network, auth token |
| 3 | IRN + QR received | Duplicate invoice number |
| 4 | Print/email with IRN | Buyer reject without QR |
| 5 | GSTR-1 auto-fetch | Mismatch if manual edit |
Fields IRP validates strictly
- Supplier GSTIN, buyer GSTIN valid
- Document number unique FY-wise
- Taxable value, tax amount calculation
- HSN mandatory length rules
- Place of supply / IGST vs CGST correct
Wholesale bulk 150 line — one error whole IRN fail. Master data clean before go-live.
High volume distributor tips
- Batch IRN: Invoices save queue — auto IRN background
- Fail queue: Retry list morning — fix GSTIN typos
- No dispatch without IRN: Policy when mandatory
- Separate B2C if any: Retail counter exempt path
- API credentials renew: Calendar reminder before expiry
Cancel and amend
IRN generate ke 24 hours me cancel possible — stock reverse, invoice void. After 24h — credit note mechanism, new invoice if needed. Wrong IRN live dispatch = painful correction. Pre-dispatch IRN verify habit.
