Check the connection to TallyPrime, list loaded companies and show backup settings.

List ledgers with their group and opening/closing balance (positive = Cr, negative = Dr as Tally reports).

List stock items with group, base unit and closing quantity/value.

List masters of a type: group, stock_group, godown, unit, cost_centre (also ledger / stock_item, names only).

Full details of one master. Ledger: group, opening balance, bill-wise, address, state, pincode, GSTIN, PAN, contacts. Stock item: group, unit, opening stock, GST rate, HSN. Others: parent etc.

List voucher types with their base type (e.g. "SALES GST-RD" -> Sales).

List vouchers in a date range with their entries. Each row has master_id, which alter_voucher / delete_voucher use. Roughly 5 seconds per month of data, so keep ranges short.

Get one voucher in full by master_id (or guid, or date + voucher_number + voucher_type).

List the automatic/manual data backups (newest first) with their folders.

Take a backup of the company data folder now (copied to Desktop\Tally Backups). Write tools already do this automatically.

Create a voucher in Tally (Payment, Receipt, Journal, Contra, Sales, Purchase, Credit/Debit Note, Stock Journal or any custom type). Accounting vouchers: give ledger_entries only (Debits must equal Credits). Item invoices: give inventory_entries (stock items, each posting to a sales/purchase ledger) plus ledger_entries for the party and any tax / round-off ledgers; items count as Cr when going out (sales) and Dr when coming in (purchase). Stock Journal (godown transfer, manufacturing, adjustment): give stock_out (source/consumption) and/or stock_in (destination/production). GST is not computed automatically: pass CGST/SGST/IGST ledger lines with amounts.

Modify an existing voucher. Identify it with master_id (preferred). Only the fields given in changes are modified; everything else (GST details, bank details, addresses...) is sent back unchanged. changes.ledger_entries REPLACES all ledger lines (for item invoices: the party/tax lines); changes.inventory_entries REPLACES all item lines; changes.stock_in / stock_out REPLACE the Stock Journal lines. Totals must still balance. An existing single bill reference on a ledger is kept automatically if you omit bill_allocations for it.

Permanently delete a voucher from Tally (a backup is taken first). Identify it with master_id (preferred). Requires confirm: true. Show the user the voucher (get_voucher) and get their approval before calling this.

Create a ledger (party, bank, expense, income, tax...).

Modify a ledger: rename (new_name), group, opening balance, bill-wise, address, state, pincode, GSTIN, PAN, contacts. Only given fields change. Opening balance changes are two-step: the first call only returns current vs new values for the user to approve.

Create a stock item with unit, group, opening stock, GST rate and HSN.

Modify a stock item: rename (new_name), group, unit, opening stock, GST rate, HSN, description. Only given fields change. Opening stock changes are two-step: the first call only returns current vs new opening figures; ask the user, then repeat with confirm_opening_change: true.

Create an account group, stock group, godown, unit (name = symbol, e.g. "KG") or cost centre.

Modify / rename an account group, stock group, godown, unit or cost centre. Only given fields change.

Permanently delete a ledger, group, stock item, stock group, godown, unit or cost centre (a backup is taken first). Tally refuses if it is still used by vouchers or other masters. Requires confirm: true; get the user's approval first.

Advanced escape hatch: import raw Tally XML objects (the content that goes inside ), e.g. a or with ACTION="Create"/"Alter"/"Delete". Prefer the specific tools.
