Which Tally Prime release supports native GST IMS integration?

Tally Prime Release 6.1 (and later versions) includes full native support for the GST Invoice Management System (IMS), allowing direct JSON import, potential matching, and action tagging.

How do I fix minor invoice number format differences in Tally IMS?

Open the IMS Inward – Voucher Register screen, press F8 (Potential Matches). Select the mismatched record and press Alt+W (Copy Doc No. & Date) to align Tally books with the GST portal format instantly.

Can Tally Prime auto-ignore round-off differences during IMS matching?

Yes. In Tally Prime IMS configuration (F12), you can set a round-off tolerance limit (e.g. ₹1 or ₹2) so minor rounding variations between vendor bills and portal entries auto-reconcile cleanly.

How does TrulyInvoice connect with Tally Prime for purchase voucher entries?

TrulyInvoice uses an automated local connector over Port 9000. It parses vendor PDFs via AI OCR and posts verified F9 Purchase Vouchers directly into your Tally Prime company in 15 seconds.

1. Accessing the IMS Dashboard in Tally Prime

With the rollout of Tally Prime Release 6.1, businesses can perform complete GST Invoice Management System (IMS) reconciliation inside their primary accounting software.

To open the IMS report in Tally Prime:

Press Alt+G (Go To) and type Invoice Management System (or go to Gateway of Tally > Display More Reports > GST Reports > IMS Inward Supplies).
Press Alt+O (Import) > GST Data to import the downloaded IMS JSON file from the GST portal.
Tally Prime categorizes transactions into Reconciled, Unreconciled, Potential Matches, and In Books Only.

2. Master Tally IMS Shortcuts: F8 & Alt+W

Minor formatting differences (such as leading zeros in invoice numbers or INV/2026/01 vs INV-2026-01) cause automatic reconciliation to fail. Tally Prime provides specific hotkeys to resolve these in seconds:

F8 — Potential Matches

Pressing F8 inside the IMS Voucher Register isolates bills where taxable value and GST amount match perfectly, but document dates or invoice numbers differ slightly.

Alt + W — Copy Portal Doc Details

Select the matched portal entry and press Alt+W. Tally automatically copies the portal's document number and date into your voucher, completing the match instantly.

Eliminate 100% of Manual Typing & Mismatches

Auto-post verified F9 Purchase Vouchers directly to Tally via local Port 9000 connector.

Reconciliation bottlenecks exist because accountants type vendor bills manually into Tally. Typing mistakes in invoice numbers, date formats, or round-off amounts create artificial IMS mismatches.

TrulyInvoice AI Automation: Upload supplier PDF bills or WhatsApp photos. AI extracts line-item HSN codes, invoice numbers, and tax totals, posting verified F9 Purchase Vouchers directly into Tally Prime in 15 seconds via Port 9000 local sync.

3. Action Tagging & Re-computing GSTR-2B

Once transactions are verified, tag actions in Tally Prime:

Select vouchers and mark as Accepted, Rejected, or Pending.
Click Export > GST IMS Responses to generate the updated JSON payload and upload it back to the GST portal.
Press Alt+Z > Re-compute GSTR-2B to sync your internal ITC summary with portal changes before filing GSTR-3B.
