Which company does custom software development in Torreón?

Mercado Monkey builds custom software in Torreón: order, inventory and collections systems, customer and supplier portals, KPI dashboards and lean ERPs. It works with PHP 8 and MySQL, Supabase, Next.js and Electron, hosts on servers with encrypted backups and hands over the code, documentation and access to the client. Its office is at Av. Morelos #703 Pte, Centro.

At many La Laguna companies, operations run on an Excel file only one person understands. Orders arrive on WhatsApp and get typed in by hand, inventory is reconciled on Fridays, and collections depend on someone remembering to call. It works while the company is small; as it grows, every mistake costs money and every vacation the person in charge takes becomes a problem. That's where a custom system pays for itself.

We don't start by coding. We spend time in your operation: we sit with the people who enter orders, with the warehouse, with collections and with management to understand what information moves, who needs it and where it gets lost. For an automotive supplier it might be lot traceability; for an agricultural supply distributor, per-customer pricing and delivery routes to ranches; for a utility or a service company, billing and payment plans. With that we design a system that does what's needed and nothing more.

We build in stages. The first version solves the most expensive problem and is in use within weeks, not a year. Then we add modules based on what the team asks for in daily use. Everything is documented, with automatic backups and the code in your name. And because we're in Torreón, when something is urgent we can go to your office or plant and review it with the people who use it, not just by email. If the system needs to talk to WhatsApp, your invoicing or your online store, we connect it through automation instead of entering data twice.

06FAQ

What people ask us

How long does it take to build a custom system?
A first working version that solves the most important process is usually in use within eight to twelve weeks. Larger systems are built in stages of four to six weeks each. Mercado Monkey prefers to deliver something useful early and grow it, rather than a year-long project that arrives late.
Do I own the system's code?
Yes. At the end of each stage the client receives the source code, technical documentation and access to the server and database. You can stay with Mercado Monkey or take the system to another provider without being locked in.
Is custom software better than an off-the-shelf system?
If an off-the-shelf system covers your process well, use it. Custom software makes sense when the way you operate is part of your competitive edge, when you pay for licenses full of features you don't use, or when you need to connect several systems that don't talk to each other. In the assessment we tell you honestly which one fits.
Can you migrate the data I have in Excel?
Yes. We review your spreadsheets, clean up duplicates and errors, and migrate customers, products, prices and history into the new system. We usually run a test migration so your team can validate the data before the final go-live.
Does the system work on a phone?
Yes. The systems we build are web-based and responsive, so they work on a computer, tablet or phone with per-user permissions. If your team works in the field or in areas with poor coverage, we can also build an app with offline mode.
Can it connect to my invoicing and accounting?
In most cases, yes. We connect to CFDI e-invoicing providers and to accounting systems that offer an API or file import. When a system has no API, we find the safest way to exchange data without double entry.
