Stop selling hours. Start shipping products.

Clients want fast, working software they own. Open Mercato enables fixed-price projects on a reusable foundation with sensible margins.

the math

Same client project. Completely different economics.

A typical CRM/portal project for a mid-market client. Here’s what changes when you stop building from scratch.

3× the margin.

Same scope. Same price to the client. 4 weeks instead of 17.
Your workflow

Clone → Overlay → Ship → Repeat.

  1. 01

    Clone the base

    Fork Open Mercato for the new client. Auth, CRM, design system — running in 5 minutes.

    Day 1
  2. 02

    Overlay their workflow

    Your team (or AI agents) drops files in src/apps/. Core never modified. Clean separation.

    Week 1–3
  3. 03

    Ship & handoff

    Client gets a fully-owned codebase on their infra. No vendor lock-in. No recurring platform fees.

    Week 4
  4. 04

    Maintain & upsell

    Sell ongoing feature development. Each overlay is scoped — easy to estimate, profitable to deliver.

    Ongoing
What your team gets

Mid-level devs ship senior-quality output.

The architecture and AI guardrails do the heavy lifting. Your team learns real skills — not workarounds.

Architecture that enforces quality

OCP overlays mean your devs can’t accidentally break core modules. The structure prevents the mistakes before code review catches them.

AI agents that follow the rules

AGENTS.md and .ai/specs/ ship with the repo. Claude, Cursor, Copilot — they all generate code that fits the architecture, not fights it.

Real AI engineering skills

Your team learns spec-driven development and context-first workflows. Skills compound across projects.

Enterprise security out of the box

Field-level encryption, RBAC, audit trails, GDPR. Stop spending 3 weeks on auth for every client. Pass security reviews on day one.

Reusable across clients

Build a logistics overlay once. Use it for 5 clients with minor customization. Your IP compounds. Your margins grow.

No vendor lock-in (for you or them)

MIT licensed. Client gets full source. You’re not reselling someone else’s SaaS — you’re delivering owned software on open infrastructure.
