About Mesh Connector · Warren, Michigan

Thirty years of enterprise software. One senior engineer on your project, end to end.

Mesh Connector was founded by Mike Cali on a simple observation: most ERP consultants advise, hand you a slide deck, and leave. Distributors don't need more advice — they need working software. So we build it.

The Founder

Who you're actually hiring

Mike Cali has spent 30+ years inside enterprise software — Epicor Prophet 21, Microsoft SQL Server, and the distribution systems that run wholesale businesses — and now the AI tooling that's changing how those businesses operate. Every Mesh Connector engagement is led hands-on by the same senior engineer: the person who scopes your project writes the code that ships it.

Engineers, not advisors

We work inside Prophet 21 — SQL, DynaChange, the P21 API — not around it. When we recommend an approach, it's because we've built it before, and we show our work before we start.

Proof, not promises

Our portfolio is live and public: P21 NextLevel, the Leads CRM, and Ginger. Click around them before you ever talk to us — the software speaks for itself.

You own everything

All code and IP transfers to you. Transparent published rates ($125–$175/hr), no long-term contracts, no lock-in. If we do a good job, you'll come back — that's the whole retention strategy.

Track Record

What we've built — and run in production

These aren't mockups. They are live systems reading and writing real Prophet 21 data today.

P21 NextLevel

A modern web workspace over a live Prophet 21 database — service-item management with draft-and-review workflows before anything touches the ERP. The template for every client portal we build. p21nextlevel.com

Leads P21 NextLevel

A lead-to-first-sale CRM with an AI enrichment pipeline: company discovery, brand audits, contact finding, and opportunities that flow into P21 as customers, ship-tos, and contacts. leads.p21nextlevel.com

Ginger — our own AI on our own phone

The AI executive assistant we sell is the one we use. Ginger triages our inbox, researches leads into our CRM, and answers +1 (586) 271-0980 24/7. Call it right now — that's the product demo.

AI service-order capture

A field app that photographs an equipment nameplate, extracts the details with AI, and writes the service order into Prophet 21 through the transaction API — no retyping, no lost paperwork.

Talk to the engineer, not a sales team

Tell us about your P21 setup, your integration headache, or the process your team still does by hand. A real engineer reads every submission and replies within one business day.
