sales_register

Read-only

Reads Sales and Credit Note vouchers in a date window that touch Duties & Taxes ledgers, returning each GST duty head and amount from TallyPrime ledger masters; it is a books register, not a GST return.

Instructions

Read-only: a register of what the books record, not a GST return. It does not decide the place of supply, the tax rate, whether tax is payable or which part of a return a sale belongs in, matches nothing against any portal, checks no GSTIN (party_gstin is returned only when the voucher carries one), returns reference_date only when the voucher carries one, as Tally sent it (reference likewise; measured on one synthetic book, on one Purchase and not on a sale), and never sums tax across heads or vouchers. It does not treat exports, sales under reverse charge or advances specially: a voucher that touches a Duties & Taxes ledger is listed by the rule below and nothing more. A GST duty head does not say whether a ledger is input or output, and a Credit Note can be a sales return or a credit note issued to a supplier: each row carries party_group (the voucher party's predefined group, for example Sundry Debtors or Sundry Creditors, when it resolves) and the tool does not guess which it is. A Debit Note, including one issued to a customer, is not a sales row: it is listed apart by identity and ledger names, with no amount. It inherits the compliance read's refusals (an INR base currency is required; a book too large to list is refused; see ledger_masters) and refuses with register_master_mark_unavailable when Tally does not report the master-alteration mark. Each page re-reads the masters and the window, so rows can shift between pages. Return the Sales and Credit Note vouchers of a date window that touch a ledger under Duties & Taxes, with the tax each entry carries taken only from the GST duty head recorded on that ledger's master -- never from a ledger name and never from an amount. Reads the full voucher window before pagination (use narrow dates) and the ledger masters twice, before and after it. Per row: tax_in_books lists each entry on a ledger whose head ComplyEaze Bridge recognises as {ledger, head, raw_head, amount} (each entry also carries what the vouchers read carries on it, among it cost_centre_allocations, whose cost-centre and category names are masked as vouchers masks them); duties_taxes_entries_without_gst_head lists entries on Duties & Taxes ledgers that carry no GST head and never assigns them one: observation not_tax_ledger is a ledger whose own tax type is not GST (usually TDS or another payable), absent is a ledger with no head whose tax type is GST or was not reported, which may be a GST ledger whose head is missing (tax_type says which); duties_taxes_entries_with_unrecognised_head lists entries whose head is not in the recognised vocabulary or contradicts the ledger's tax type, with the raw spelling and its observation; entries_on_ledgers_with_unresolved_group lists entries on ledgers whose group chain could not be resolved; taxable_entries are entries on Sales Accounts ledgers only (a sale booked to another ledger, or whose sales ledger sits in an inventory allocation, has has_taxable_entry false); party_entries are the voucher party's own; other_entries is everything else (round-off included) with no role inferred. status is the first that applies of head_conflict, has_unrecognised_head, has_unresolved_group, has_entries_without_gst_head, has_other_entries, complete. The response state follows the rule vouchers uses: complete only when every voucher read was checked against a separate count of the window (a census, which ComplyEaze Bridge sends for every book that has held a voucher, however few), otherwise partial with reason nonempty_window_unqualified and the rows still returned; an empty window is complete when its corroboration read confirms it. A row's status is separate: it says whether every entry the voucher touches classified, and the state does not change it. Amounts are as the books state them (negative is a debit), never re-signed and never summed across heads; there is no input-credit or direction field. reference, party_gstin, is_invoice, post_dated follow vouchers: absent means not observed, and cancelled, optional and post_dated vouchers are returned flagged, not excluded. Every other voucher type that touches Duties & Taxes (Purchase, Journal, Payment and so on) is listed apart in other_voucher_types_touching_duties_taxes, not in items: whether it belongs in a return is the CA's call. A voucher with no resolved class is listed under unclassified_voucher_type; a voucher that touches only unplaceable ledgers under vouchers_with_unplaced_ledgers; a Sales or Credit Note voucher with no entry on a Duties & Taxes ledger under sales_vouchers_without_duties_taxes_entry (listed by identity only; the tool does not say why such a voucher carries no tax entry). A cancelled sale that Tally returns with no ledger entries is listed there too, with cancelled true; no cancelled sale has been read, so whether one keeps its entries is not measured. Rows are in items (paged by offset and limit like vouchers); each has has_taxable_entry, false when no entry sits on a Sales Accounts ledger (a sale typed on Tally's screen, or an item invoice of another shape than the imported one that was measured, may hold the sales ledger in an inventory allocation instead; not measured). The side lists carry exact counts (total) and at most 100 items (listed); every ledger name in the response is masked like vouchers masks it. A voucher that names a ledger the masters do not list, a master or voucher that changed while the window was read, or a ledger set aside for its currency, refuses (ledger_snapshot_drifted, voucher_window_changed_during_read, register_ledger_currency_excluded) and releases no rows; a row dated outside the window refuses as window_not_honoured, or as voucher_window_part_not_admitted when the window was counted. A sgst_utgst head is a state-side head that a consumer summing state tax must include alongside state_tax. Measured so far: sales_register was run against a live Tally on two synthetic companies. On the first, once per day, for one taxed Sales item invoice and one untaxed one: the taxed sale came back as one row with its CGST and SGST/UTGST heads taken from the ledger masters and its sales ledger as the taxable entry, and the untaxed one (read once by an earlier build; its voucher window is committed, its masters and the tool's answer are not) was counted under sales_vouchers_without_duties_taxes_entry. On the second, which has 44 ledgers, for one Credit Note in voucher view booked on account: one row, with its CGST and state-tax heads and its sales ledger as the taxable entry. One Sales accounting voucher (not an invoice) was also classified, in tests, against the ledger masters of the purchase register's lab book. A Credit Note is returned as a row with its signs reversed as Tally sends them: the tool neither nets nor flips, so a caller that sums tax over a window must add signed amounts. The measured Credit Note of 1,000.00 with 90.00 CGST and 90.00 State Tax came back with the sales entry -1000.00, each tax entry -90.00 and the party entry 1180.00, where a Sales row has the sales and tax entries positive and the party entry negative. The state-side tax head is state_tax (raw State Tax) on one measured book and sgst_utgst (raw SGST/UTGST) on another; both are recognised heads for the same side of the tax, so a caller must not look for one of them only. The cost of a call varies by book: 102 requests on a book with 8 ledgers and one currency (96 were recorded before a small book was counted, plus the six the count adds; not measured since), 118 on one with 44 ledgers and two currencies, which adds base-currency reads; the result does not report the cost. Not shown by any run: an invoice-view Credit Note; an inter-state (IGST) line; a cancelled or optional sales voucher; an unrecognised or missing duty head on a sale; more than one voucher in a window; paging; a company with a registration; a tax that Tally computes itself; a sale typed on Tally's screen; accounting-invoice mode; a post-dated sale; a REFERENCE or a populated PARTYGSTIN on a sale; a REFERENCEDATE on a sale; and a ledger or voucher kept in a currency other than the book's base. A row of such a kind is returned, not withheld, and carries not_measured_live naming why (invoice_view_credit_note, inter_state_line, sales_ledger_not_an_entry, cancelled, optional, post_dated, party_gstin_present, reference_present) only where the row itself shows the kind. Kinds a row cannot show are never marked and are not vouched for: a sale typed on Tally's screen in voucher view, a tax Tally computed itself, a duty head no sales capture has (such as cess), an invoice of another shape than the one run (for example several goods lines), and a ledger or voucher kept in a currency other than the book's base; an unmarked row is not a measured one in those respects. A row is marked inter_state_line only when a tax entry's ledger master carries a recognised IGST head; an IGST ledger with no head, or an unrecognised head, is listed under the without-head or unrecognised list and the status is not complete. Each call appends metadata-only receipt lines (tool, company, counts, request and response fingerprints; no book content) to ComplyEaze Bridge's local log on this computer; it writes nothing to Tally.

TDQS

A3.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Extraordinarily explicit about behaviour beyond the annotations: write-free operation ('writes nothing to Tally'), local metadata receipt lines per call, refusal codes (`register_master_mark_unavailable`, `ledger_snapshot_drifted`, `voucher_window_changed_during_read`, `register_ledger_currency_excluded`, `window_not_honoured`), request cost per book (102/118), and the fact that rows can shift between pages because masters are re-read each page. All of this is consistent with readOnlyHint=true, destructiveHint=false, idempotentHint=false – the page-shift and receipt-log notes actually explain why the tool is not idempotent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Roughly two thousand words of undifferentiated prose with no headings or bullets, in which operational guidance, measurement anecdotes ('measured so far: run against a live Tally on two synthetic companies', 'one measured book', 'not measured since'), and exhaustive negative caveats are interleaved. The single most important sentence is buried mid-document and most of the text - unmeasured-kind enumerations, per-request counts, historical test narration - does not help an agent decide or call.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description carries the return-shape burden and does discharge it: `items` plus the side lists with `total`/`listed`, per-row `tax_in_books`, `duties_taxes_entries_without_gst_head`, `taxable_entries`, `status` precedence, and response `state`. It is complete to a fault, though the pervasive `not_measured_live` hedging leaves several common cases (IGST lines, cancelled sales, paging) described as unverified rather than defined.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning: it explains that the voucher window is fully read before pagination and advises narrow dates, that rows dated outside `from`/`to` cause a `window_not_honoured` refusal, and that `offset`/`limit` page like `vouchers`. It does not restate the parameter definitions, which is correct, but it does deepen the consequences of the date range.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Return the Sales and Credit Note vouchers of a date window that touch a ledger under Duties & Taxes, with the tax each entry carries taken only from the GST duty head'), and explicitly distinguishes the tool from a GST return, from `vouchers`, and from `purchase_register`/`ledger_masters`. The drawback is placement: the core purpose sentence sits several hundred words in, behind a long list of disclaimers, so an agent skimming will see ten negatives before it sees what the tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description is overwhelmingly about when NOT to expect things (no place of supply, no rate, no portal matching, Debit Notes excluded), and it names `ledger_masters` for shared refusals, but it never states a positive selection rule such as 'use this rather than vouchers when you need GST-head-tagged sales rows'. Lifecycle guidance (use narrow dates, every page re-reads the window) is present and genuinely useful, but the use-vs-alternative framing is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
