Why work with Sistemas Leal
Your code, no lock-in
Everything we build is yours. The code is yours — leave whenever you want.
Custom-built, never a template
Built around how your business runs, not a theme we resell to everyone.
Support via WhatsApp
A direct line to the person who built your system. No ticket queue.
Made in Mexico
A Mexican team, for Mexican SMBs — because we're one of them.
What we do
Technology with purpose, not just marketing.
Every solution is built around how your business actually runs — not the other way around. No cookie-cutter packages, no fine print, no surprises.
Custom Software
Inventory, bookings, POS, work orders. We build it around your workflow — we don't ask you to change yours.
AI Consulting
We identify where AI saves you real hours: customer service, quotes, follow-ups, reports. Applied AI — not a demo.
Systems Integration
Your POS, inventory, accounting and CRM talking to each other. Stop entering the same data three times.
Custom AI Agents
Not a generic bot — a digital employee that knows your catalogue, books for you, replies on WhatsApp and Instagram, and hands you the lead when it's hot.
What you get
What changes when the system works for you.
These aren't pitch-deck promises — they're what we commit to, in writing, from the first conversation.
Why us
Made in Mexico, for Mexican SMBs.
We're a Mexican team, not a fly-in agency. We know the rhythm, challenges and opportunities of Mexican SMBs — because we're one of them.
SMB budget, not enterprise pricing
AI and custom software are no longer just for big chains. We scope the project to the size of your business — not the other way around.
We speak your language — literally
Bilingual team, bilingual AI agents. We understand both the Mexican market and the international economy that drives it.
Support with a name and a face
When something breaks or you have questions, you don't call a helpdesk. You have the direct WhatsApp of the person who built your system.
How we work
From idea to system in 4 clear steps.
No jargon, no endless phases, no surprise invoices. You weigh in at every step and see progress every week.
We talk
20 minutes. You tell us how your business runs and what keeps you up at night. No cost, no commitment, no sales pitch.
We design
We show you what your system would look like before writing a single line of code. We adjust until you say "that's exactly what I need."
We build
Your system grows before your eyes. Demo every week — no black boxes, no "almost done," no surprise bills.
We grow together
We deliver, train your team and stay. Your system evolves with your business — we don't disappear the day after launch.
