Custom software development in Guadalajara
Web platforms, portals, system integrations and AI modules that work with your data and your team, for what no off-the-shelf software solves. The first phase goes live before the project ends, and everything stays in your name.
Guadalajara, Jalisco
What we build
WITS is a software company based in Guadalajara. We develop custom systems for companies that already tried a generic ERP, spreadsheets or a vendor that never finished.
We build web management platforms, customer and supplier portals, apps for field teams, integrations between systems that don't talk to each other, and artificial intelligence modules inside the software: document classification, agents that handle requests and act on them, data analysis.
The team that designs is the team that codes, in short cycles with a demo every week.
Software already in operation, not prototypes
State investment CRM
Investment project management platform for the Government of Jalisco.
ISO 9001 management system
Platform with 16 modules for ISO 9001 compliance.
500M+ coupon campaigns
Platform to run massive free mobile data campaigns for Coca-Cola, GEPP and Bimbo. AWS infrastructure with load balancers and RDS Aurora.
What can we build for your operation?
Custom software doesn't mean starting from scratch. It means building the missing piece and connecting it to what you already use. These are the areas where we get asked most.
Customer service
A self-service portal where customers see their orders, invoices and tickets without calling; a support desk connected to your CRM or ERP.
Sales
A quoting tool with your catalog and pricing rules, a CRM adjusted to your process, and PDF proposals on your letterhead generated from the system.
Operations
Order, inventory, production or logistics system; an app for field teams that works offline and syncs later.
Administration and finance
Approval flows for purchases and expenses, reconciliations against the ERP, and the reports that today come out of a hand-built spreadsheet, with data extraction from invoices and PDFs when needed.
Engineering and IT
API integrations between systems that don't talk to each other, and rescue of legacy systems: migration and documentation of code left behind by another vendor.
Leadership
Dashboards with the real state of the operation from every source: one number instead of three versions of the same figure.
Problems we solve
- Our process doesn't fit in the ERP or the CRM, and the team lives in spreadsheets to make up for it.
- Each department has its own spreadsheet for the same process and nobody knows which version is right.
- A previous vendor left us an undocumented system nobody dares to touch.
- We need a portal for customers, distributors or branches, and none exists for our industry.
- We want to bring AI into operations, but our data lives in closed systems.
- We handle customer or financial data that can't live in just any SaaS; we need the system hosted where we decide, with role-based access.
How we do it
A custom software project almost always fails because of scope, not technology. That's why the process starts before any code is written.
- 1
Discovery
Sessions with the people who run the process today. We come out with scope, a clickable prototype and a fixed quote by phase.
- 2
Build in phases
The first phase goes to production before the project ends, not at the end. Real users on your team test it, not just us.
- 3
Integration
We connect to what you already use: ERP, CRM, CFDI invoicing and stamping, WhatsApp Business, banks. Through an API or, when there is no API, with automation.
- 4
Handover and support
Code, infrastructure and documentation in your name. Support and evolution on a monthly plan if you want it, with no lock-in.
No made-up percentages: the metrics are defined with you before we build and measured afterward.
What you get from discovery
Discovery is real work, not a sales pitch. It ends with a document you can use with us or with whoever you choose.
- A map of the process as it runs today: the screens, spreadsheets and emails each request goes through, and the step where it stalls.
- Automation opportunities, separated from the things better left as they are.
- Where AI belongs inside the system and where a rule or a form is enough.
- Proposed architecture: what gets integrated, how, and what's needed on your systems' side to make it happen.
- A clickable prototype of the first phase, validated with the people who will use it.
- Estimated effort and schedule, and a fixed price per phase.
- Expected impact and metrics defined with you, to measure them after go-live.
- A clear recommendation to do it or not, and where to start if you do.
A software team you can meet in person
Discovery sessions and demos are held in person at your company, in any municipality of the metro area. We sit down with the people who run the process, not just with whoever hires us.
Here we built, among others, the investment project management system for the state Ministry of Economic Development and QualityWeb 360, an ISO 9001 compliance platform with 16 modules used today by certified companies. With companies in other cities we work remotely, with visits at key milestones.
WITS is a good fit if…
Not every process needs custom software. It makes sense when the missing piece doesn't exist as a product, or when adapting one costs more than building it.
- You have someone on the business side who can spend a few hours a week validating what gets built.
- You already have systems that work, and what's missing is the piece that connects them, not a replacement.
- The process is already clear and lives in your people's heads; what's missing is the system to support it.
- You'd rather start with one module in production within weeks than wait for a complete system at year end.
- You want AI to operate inside your system (classify, extract, handle requests) with permissions and traceability.
- You need the code and infrastructure in your name so you don't depend on a vendor.
What people ask before hiring us
How much does custom software development cost?
Discovery is a short, fixed-price project; development is quoted by scope and by phase, with a fixed price per phase. When discovery ends you have a number, a schedule and a prototype before committing to the full build. We don't bill open-ended hours.
How soon will I have something working?
It depends on the scope of the first phase, which is defined in discovery. We'd rather deliver a module your team already uses and build on it than a complete system that arrives late. The schedule per phase is written down before we start.
Do I own the code?
Yes. Source code, repository, infrastructure and documentation are in your company's name. You can continue with us or with another team without depending on anyone.
Can you integrate with my ERP or my invoicing system?
Yes. If your system has an API we connect directly; if it doesn't (many local ERPs don't expose one), we automate data entry or work on its database with read permissions, so nobody has to retype the same information again.
Do you build mobile apps?
Yes, when the process happens in the field: salespeople, technicians, supervisors, drivers. Usually as a progressive web app or a native app depending on the case, always connected to the same central system.
Do you include artificial intelligence in the software?
When it adds value. Classifying documents, extracting data from PDFs and invoices, handling chat with customer context or answering questions about your information. The AI lives inside the system, not as a separate product.
We review your process in 30 minutes
Tell us which process you want to systematize. We review how it runs today and tell you whether it makes sense to build it, adapt something that already exists or leave it alone, and what it would take to quote it by phase. No cost, no commitment. At your company if you're in the metro area; remotely for the rest of Mexico.
