Step 01
Upload + local validation
CSV uploaded or ERP feed pushed. Local schema validation runs per row. Errors surface before any GSP call.
GST E-Invoicing Software | Bulk E-Invoice Generation
Bulk IRN from CSV, ERP feed or API. With auto-retry on failures.
Generate IRNs in bulk from a CSV upload, an ERP feed (Tally, SAP B1, NetSuite) or programmatic API calls. Each invoice validated locally, then relayed via the authorised GSP. Failures auto-retry with exponential backoff. Status post-back per IRN.
How it works
From bulk file to bulk IRN.
Step 02
Parallel IRN calls
Validated rows fan out to parallel GSP calls. Throughput typically 200 IRNs per minute.
Step 03
Auto-retry on failures
Transient GSP/IRP outages trigger exponential-backoff retry. Permanent failures (schema errors) surface for fix-and-resubmit.
Step 04
Status post-back per IRN
Each row gets a status (success with IRN, pending with retry count, failed with reason). Dashboard updates in real time.

Compliance + integrations
Bulk, but per-IRN auditable.
Bulk generation does not relax compliance. Each IRN is validated, signed and stored individually. The audit trail is per-IRN, not per-batch.
Regulations we work within
-
Rule 48(4), CGST Rules
Each IRN compliant with the GSTN schema.

Bulk E-Invoice Generation FAQ
What buyers ask.
How fast is bulk?
Throughput is typically 200 IRNs per minute, depending on GSP latency. Bulk of 10,000 invoices completes in under an hour. Auto-retry handles transient failures without losing throughput.
What if some rows fail validation?
Only validated rows go to GSP. Failed rows are reported with field-level error messages. Fix and resubmit just the failed rows; successful rows are not re-processed (idempotency).
Can we get an idempotency guarantee on the API?
Yes. Each API call carries an idempotency key. Repeated calls with the same key return the original IRN, not a new one. Network-retry-safe.
