Where AI agents meet commerce.

Commerce is becoming agentic — software that buys, sells, and operates on our behalf. ACJ Labs builds the products and infrastructure for that world: focused, inspectable tools that do messy jobs reliably, with honest confidence and no black boxes. Free tier, no card — start from any MCP client or a one-line npm package.

Catalog data that checks its own work

Our Catalog Attribute Normalizer cleans messy product data from multiple sources and maps it into the Google and Shopify taxonomies — but it doesn't trust the model's memory. Every category ID is verified against the real, current taxonomy file, and each result carries an honest confidence score.

Retrieval-grounded classification — 11 of 12 exact category+ID matches on the Google side of our 12-product evaluation set, measured against the live service
Returns a real leaf_id or an honest null — never a fabricated one
Size/color/attribute canonicalization to a fixed vocabulary

Receipts that know the tax rule

Our Receipt Extraction service turns a receipt or invoice image into structured data — vendor, ABN (checksum-validated), GST-aware line items — and it understands Australian GST rules most OCR tools ignore, like entertainment ITC denial and the exceptions that flip it back.

Per-line tax_code, confidence, and a plain-English rationale naming the actual rule applied
Knows a client dinner (ITC denied) from an in-flight meal on a business trip (claimable) — same-looking receipt, different rule
ABN checksum validation built in

@acjlabs/google-taxonomy-verify

import { isVerifiedGoogleLeafId } from "@acjlabs/google-taxonomy-verify";

// Does this ID exist — AND does its real path match what was claimed?
isVerifiedGoogleLeafId("212",
  ["Apparel & Accessories", "Clothing", "Shirts & Tops"]); // true
isVerifiedGoogleLeafId("212",
  ["Apparel & Accessories", "Clothing", "Outerwear"]); // false — path mismatch
isVerifiedGoogleLeafId("999999", ["Anything"]); // false — ID doesn't exist
