TallyPrime (CA) Skill

Connect to a locally running TallyPrime instance via its XML-over-HTTP interface. All requests are HTTP POST to $TALLY_URL (commonly http://localhost:9000) with an XML body.

• No cloud API: TallyPrime must be open/running on the user’s machine.
• Multi-company: Always use the correct SVCURRENTCOMPANY (exact spelling).

Hero Use Case: WhatsApp invoice → Tally entry

Goal: zero manual entry for CAs handling many clients.

1. Read bill/invoice (PDF/image) and extract: company, party, GSTIN, date, invoice no, taxable, tax, total, ledger mapping.
2. Ensure masters exist: party ledger, purchase/sales ledger, GST ledger(s), bank/cash ledger (if needed).
3. Post voucher with a unique GUID.
4. Confirm a summary back to the user.

When to use this skill

Use when the user asks to:

• Post entries: purchase, sales, receipt, payment, journal, contra, credit note, debit note
• Check reports: day book, trial balance, balance sheet, profit & loss, ledger statement, outstandings, GST
• Manage masters: create/alter ledgers, groups, stock items/UOM (inventory clients)
• Fix data: alter or cancel a voucher

Critical rules (must follow)

1. Never assume company: if not explicit, ask which company to use before posting.
2. Never guess ledgers: verify ledgers exist before voucher import; create missing masters first.
3. Dates are YYYYMMDD (no separators).
4. Idempotency: always set a stable unique GUID per voucher to prevent duplicates on retries.
5. Balance vouchers: total debits must equal total credits (Tally error: “Voucher totals do not match!”).
6. Escape XML: narration/party names may contain & → use & in XML.
7. Posting is write operation: confirm intent (and company) before any create/alter/cancel.
8. Prefer bill-wise allocations for party ledgers to keep outstandings correct (see reference/vouchers.md).
9. Accounting-only vouchers (no inventory items): set <ISINVOICE>No</ISINVOICE> and place the party ledger entry first in the ALLLEDGERENTRIES.LIST sequence. This makes the Day Book "Particulars" column show the party name (not the expense/purchase ledger) and defaults the voucher to the clean "As Voucher" view. Only use ISINVOICE=Yes for item invoices that go through reference/inventory.md.
10. Accounting Invoice Mode — always use LEDGERENTRIES.LIST: when OBJVIEW="Invoice Voucher View" is set (Modes 1 and 2 in reference/vouchers.md), every ledger block must use <LEDGERENTRIES.LIST>, not <ALLLEDGERENTRIES.LIST>. Tally silently ignores ALLLEDGERENTRIES in this view, causing the voucher to be saved with no entries and the error "No accounting or inventory entries are available."
11. Voucher class decision — confirm before posting: before posting any Purchase or Sales voucher, check whether the company's voucher type uses a class for GST splitting. Run the preflight checklist in the "Preflight checklist before posting" section below. If class mode is confirmed, set <CLASSNAME>EXACT_CLASS_NAME</CLASSNAME> in the voucher header and include all four GST header fields (CMPGSTIN, PARTYGSTIN, GSTREGISTRATIONTYPE, PLACEOFSUPPLY). If class existence is unconfirmed, stop and ask — do not post without it. Full decision rules and templates are in the "Voucher class — decision rules" section of reference/vouchers.md.

Preflight checklist before posting

Run through every item before sending any Create/Alter/Delete request. Stop at the first unresolved item and ask the user.

Step 0: Check TallyPrime server

curl -s --max-time 5 "$TALLY_URL"

Expected (example):

<RESPONSE>TallyPrime Server is Running</RESPONSE>

If not running, stop and ask user to open TallyPrime and enable integrations for the port.

Step 1: Company context

If the user did not specify company, ask. If they did, use exact name in SVCURRENTCOMPANY.

To list companies, use the template in reference/reports.md (“Company list”).

Step 2: Verify/create required ledgers (masters)

Ledger existence checks and master creation templates are in reference/masters.md (includes ledgers, groups, GST/address fields, and party ledger creation with required field prompts).

New company? Run the "New Company Setup — Standard GST Ledgers" block in reference/masters.md first. It creates the seven minimum ledgers every GST-registered company needs:

Quick group defaults (common CA mapping):

Step 3: Post vouchers (core)

Use REPORTNAME=Vouchers and always include GUID, DATE, and VOUCHERTYPENAME. Full templates (including bill-wise allocations, returns, contra) are in reference/vouchers.md.

Supported voucher types in this skill:

• Purchase, Sales, Payment, Receipt, Journal
• Credit Note, Debit Note
• Contra
• Voucher Alteration + Cancellation

Read reports (core)

Use TALLYREQUEST=Export / REPORTNAME=... with SVEXPORTFORMAT=$$SysName:XML. Full templates are in reference/reports.md.

Common CA reports:

• Day Book (period)
• Trial Balance (period)
• Balance Sheet
• Profit and Loss
• Ledger Vouchers (ledger statement)
• Bills Receivable / Bills Payable (outstandings)
• Ledger Outstandings / Group Outstandings
• GST: GSTR-1 and related summaries (plus GSTR-3B where available)
• Stock Summary (inventory clients)

Suggested GUID pattern

Use a deterministic pattern when invoice number exists:

{companyShort}-{voucherType}-{voucherNumber}-{date}

Examples:

• abc-purchase-ril2026-00123-20260115
• abc-creditnote-cn09-20260302

Multi-company CA workflow (recommended)

1. Capture company name early (and confirm spelling).
2. Validate connectivity.
3. Fetch required ledgers/masters or create them.
4. Only then post the voucher.
5. Reply with: company, voucher type, voucher number, date, amount breakdown, and whether any masters were created.
