What is three-way-match?

A read-only procedure for a three-way match: comparing what a business ordered, received, and was billed for. It checks Acumatica purchase orders, receipts, and vendor bills line by line for price and quantity differences.

Use it to validate a vendor bill, verify received quantities and prices against the purchase order, and flag variances for review.

It helps catch billing errors before payment by connecting the three documents and comparing their details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00151	$0.01315
Opus 5.5	$0.00060	$0.00526
Sonnet 5.5	$0.00030	$0.00263

Security

Grade A, and why

three-way-match scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Acumatica - Three-Way Match (Bill <-> Receipt <-> PO)

Reconcile what was ordered (PO) vs received (receipt) vs billed (bill), line by line, and flag variances before a bill is paid. Read-only - never releases or edits a document.

⚠️ Known tenant behaviour

$orderby is silently ignored - sort client-side.
Date filters need datetimeoffset'YYYY-MM-DDTHH:MM:SS-04:00' literals.
$select/$filter field names must match exactly or you get a hard 500.
Decimal comparison filters (e.g. gt 0) may 500 with "Type conversions not supported" - filter client-side instead.
Render each document number as a Markdown link from its browser_url.

The linking chain (verified field names)

Each Bill line (Bill -> expand="Details") carries the back-references: POOrderType, POOrderNbr, POLine -> the originating PO line, and POReceiptType, POReceiptNbr, POReceiptLine -> the receipt line. Line amounts: Qty, UnitCost, ExtendedCost, Amount, InventoryID, LineType.

Each PurchaseReceipt line (PurchaseReceipt -> expand="Details") carries: POOrderType, POOrderNbr, POLineNbr (link to PO line), ReceiptQty, OrderedQty, OpenQty, UnitCost, ExtendedCost, InventoryID, POReceiptNbr, POReceiptLineNbr.

Each PurchaseOrder line (PurchaseOrder -> expand="Details") carries: LineNbr, InventoryID, OrderQty, QtyOnReceipts, UnitCost, ExtendedCost, Completed.

Goods lines carry these PO/receipt references. Non-goods bill lines (e.g. accrued warranty, freight, GL-only) have the reference fields empty - those are legitimately "no PO" and should be reported as unmatched-by-design, not as errors.

How to match a single bill

get_record(entity="Bill", id="Bill/<RefNbr>", expand="Details").
For each bill line with a POOrderNbr, pull the PO once: get_record(entity="PurchaseOrder", id="<POOrderType>/<POOrderNbr>", expand="Details") and find the line where LineNbr == bill.POLine.
For each bill line with a POReceiptNbr, pull the receipt: get_record(entity="PurchaseReceipt", id="<POReceiptType>/<POReceiptNbr>", expand="Details") and find the line where its POReceiptLineNbr/LineNbr matches bill.POReceiptLine.
Compare per line (see rules) and classify each as Match, Variance, or Unmatched.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
