Erply API
Erply publishes an open, documented API covering everything the back office and POS can do, plus purpose-built REST APIs for PIM, reports, and WMS. Access is free and self-serve, with credentials exchanged for a session key. Webhook payloads are thin, so integrators fetch back after events.

Erply scores B+ on the API Report Card. Erply publishes an open, documented API covering everything the back office and POS can do, plus purpose-built REST APIs for PIM, reports, and WMS. Access is free and self-serve, with credentials exchanged for a session key. Webhook payloads are thin, so integrators fetch back after events.
Erply has a workable official integration path. Most engineering teams can build against it directly. Solid API with minor gaps
Erply is a cloud-based retail business platform that unifies point of sale, inventory management, warehouse management (WMS), CRM, e-commerce sync, and back-office reporting in a single multi-location system.
POS / Hospitality - more specifically cloud retail POS + inventory/WMS. Retailers use Erply to: run in-store POS (touchscreen and self-checkout, online/offline), manage SKUs and inventory across many stores and warehouses, handle purchase orders and stock transfers, run promotions and loyalty programs, manage a customer database/CRM, schedule employees and track time, sync products and orders to e-commerce (Shopify, WooCommerce, Magento, Amazon, Etsy), push transactions to accounting (QuickBooks Online, Xero, NetSuite, ErplyBooks, Merit Aktiva), calculate sales tax via Avalara, and pull sales/inventory analytics from back-office dashboards.
Well-known niche player in cloud retail POS, particularly strong in Europe (Estonia/Nordics) and present in North America.
Yes, for retailers - Erply holds the operator's full retail book of record: SKU/product catalog, real-time inventory across all stores and warehouses, purchase orders, stock transfers, supplier records, sales transactions, returns, promotions, gift cards, loyalty balances, employee schedules and time records, and a CRM with customer PII, purchase history, and marketing opt-ins.
~17 years old (founded 2009 in Tallinn). Cloud-native from day one, which is older than many competitors and shows in the UI - the back office is functional but visually dated relative to Square or Shopify POS.
Legacy 'Erply API' is a sprawling all-in-one endpoint - developers must choose between several overlapping APIs (Erply API vs PIM API vs JSON API vs WMS API) without clear guidance on which to pick. Webhook/push-notification payloads are limited - integrators often have to fetch back to the REST API after a webhook fires, increasing latency and call volume. Full sourced list under Sources below.
Common alternatives include Lightspeed Retail, Square for Retail, Shopify POS, Clover, Vend (now Lightspeed Retail), Heartland Retail (Springboard). Graded alternatives appear under "More from the report card" below.
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.
