e-Invoice / GST Compliance Checklist for Mid-Size Distributors

Mid-size distributors feel e-invoice pressure in two places: the IRN attempt that fails at 7pm, and the month-end cleanup that eats a weekend. Both usually trace back to the same gap — the sales order never carried clean GSTIN, HSN, and tax context.

This checklist is for ops and finance leads who share one order pipeline with field and counter sales. It is not tax advice; it is an operating checklist so booking and invoicing stop fighting each other.

What breaks between booking and IRN

Map the handoff. Most failures are master data and process — not “the portal was down.”

• Customer without verified GSTIN (or wrong state)
• SKU without HSN / UQC that finance trusts
• IGST vs CGST/SGST mismatch vs place of supply
• Scheme or free-qty lines that confuse taxable value
• No owner for failed IRN retries

Master data gates (before you chase IRN rates)

1. Active dealers: GSTIN validated; billing state clear
2. Top SKUs by revenue: HSN + unit of measure filled
3. Price lists: taxable value rules agreed with finance
4. Credit-note / return path documented (not “we’ll figure it out”)
5. Who may override tax fields — and how it is logged

At booking: fields that must already be true

Reps should confirm — not invent — tax context. Defaults from masters beat typing GSTIN into WhatsApp.

• Customer GSTIN present or explicit B2C / exception reason
• Every line has HSN from the product master
• Tax split preview matches interstate vs intrastate expectation
• Ship-to vs bill-to clear when they differ
• Scheme lines labelled so taxable value is not a surprise later

Order → invoice handoff without Excel

One queue: booked → confirmed → invoice attempted → failed IRN. Chat is for exceptions, not the ledger.

• Ops confirms stock/cuts on the same order record
• Finance invoices from that record — no retyping lines
• Failed IRNs land in a watched list with owner + SLA
• Amend / cancel path is trained — not discovered at month-end

Monthly close checklist

1. Clear failed IRN backlog older than your SLA
2. Reconcile credit/debit notes to original orders
3. Spot-check new GSTINs added this month
4. Fix HSN gaps on SKUs that sold without codes
5. Review WhatsApp-only orders that bypassed the queue

If your e-invoice success rate depends on one person who “knows Tally,” you do not have a process — you have a single point of failure.

Pattern in mid-size distributor finance reviews

Metrics worth putting on the ops board

• % of orders with GSTIN + HSN complete at booking
• IRN success rate on first attempt
• Median hours from confirm → IRN
• Open failed-IRN age (P50 / P90)
• Count of Excel rebuilds before invoice

Vendor / system questions

• Do GSTIN and HSN travel with the sales order — or only at invoice?
• Where do failed IRNs show up, and who is notified?
• Can field booking block incomplete tax masters?
• How do free-qty / scheme lines appear for taxable value?
• What is the path from order to Tally/ERP without rekeying?
