Wherefour scores D+ on the API Report Card. Wherefour exposes a public REST API built to an OpenAPI spec, with production and sandbox base URLs and coverage across inventory, orders, invoices, and customers. Every endpoint uses HTTP BasicAuth. There are no webhooks, no OAuth, and no published rate limits.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Wherefour is a cloud-based ERP and traceability platform purpose-built for manufacturers and distributors of physical products, with deep specialization in food & beverage, beverage (brewing/distilling/coffee/kombucha), cannabis, nutraceuticals, cosmetics/personal care, pet food, apparel & textiles, automotive/marine, chemicals, electronics, and general distribution/wholesale.
Primary vertical bucket: misc (ERP / Traceability / Food & Beverage Manufacturing). A growing food & beverage manufacturer sets up raw materials, intermediates, and finished goods with SKUs, UOMs, allergen tags, vendor mappings, COA requirements, and BOMs/formulas; configures warehouses, locations, and lot-tracked bins; and connects QuickBooks Online or Desktop (or Sage Intacct / Xero / Microsoft Dynamics / Epicor) plus sales channels (Shopify / Shopify Plus, Amazon FBA) and shipping (ShipStation).
Mid within its segment.
Wherefour is the system of record for raw-material and finished-goods inventory at lot level, FIFO/FEFO/LIFO consumption order, BOMs and formulas, work orders and COGS, MRP-driven reorder and purchasing, COAs and compliance documents, and the bidirectional bridge between sales channels (Shopify, Shopify Plus, Amazon FBA, B2B portal, SPS Commerce EDI), shipping (ShipStation), accounting (QuickBooks Online & Desktop, Sage Intacct, Xero, Microsoft Dynamics, Epicor), and cannabis-specific compliance/exchange systems (Metrc, Leaf Link).
Wherefour is a mature SMB/mid-market cloud ERP, the public Zapier integration was announced in January 2018 (Snack and Bakery coverage), which puts the platform's API-and-integrations stack at minimum eight years old in market.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Wherefour API and MCP server so AI agents and internal tools can read and write Wherefour data. See the Wherefour integration docs at supergood.ai/docs/wherefour-api.
