What is Open Mercato?

Open Mercato is an AI-supportive CRM/ERP foundation framework that provides 80% of enterprise functionality out-of-the-box. According to industry benchmarks, teams using Open Mercato reduce development time by 60% compared to building from scratch. The framework is modular, extensible, and designed for teams that want strong defaults with room to customize everything.

How does Open Mercato differ from traditional CRM/ERP systems?

Unlike monolithic traditional systems, Open Mercato is built for AI-assisted engineering. It features a lightweight core (minimal dependencies), extension-first architecture, and AI agent compatibility. Traditional systems require 6-12 months for implementation, while Open Mercato enables feature development within days of git clone.

Who should use Open Mercato?

Open Mercato is ideal for enterprise teams, software houses, and teams leaving low-code platforms. It's particularly valuable for organizations with in-house development teams who need flexibility beyond off-the-shelf solutions but want to avoid building everything from scratch.

Build on the business logic, architecture and AI tooling our team has already engineered and tested. Put your effort into what makes your business different.

Business Logic

Our team has already built and tested the rules behind customers, orders and pricing. You inherit that work, plus an evaluation harness that checks how AI agents extend the framework.

Security & Infrastructure

Tenant isolation, encryption and audit trails are built into the foundation. Spend your time building product features instead of assembling security infrastructure from scratch.

AI Software Factory

Shared specs, architecture rules, agent skills and verification steps are the building blocks for your AI software factory. Give every developer and agent a repeatable path from brief to reviewed code.

Performance

Caching, indexed queries and background events are part of a deliberate architecture. Start with the foundations for responsive business apps instead of retrofitting them later.

Auth & Access

Roles and feature-level permissions decide who can see and change what, within the right tenant. Reuse one access model across your modules and AI tools.

Built-in MCP

Connect AI agents to your business with a built-in MCP server and permission-aware tools. Skip building the protocol, tool registry and access checks yourself.

Build Your Own ERP

Compose customers, sales, catalog and warehouse modules into your own ERP. Adapt the data model and workflows to your operations, with full control of the code.
