Custom software development for companies in Mexico

We build the system your operation already needs: the one that replaces the spreadsheet only one person understands, the WhatsApp group that is really a process and the report someone puts together by hand every Monday.

We are Stonework, a studio in Mexico City. We build and run our own products, and we bring the same judgment to software for other companies.

Tell us about your process

Who it is for

For the owner or director of a company that already has customers and operations, and feels the business has outgrown the way it works. Restaurants, professional firms, distributors, clinics, schools, real estate agencies.

And for founders who need to turn an idea into a first product people can use and pay for, without hiring a full team before knowing whether it works.

What we build

Internal operations systems

Inventory, attendance, shifts, end of day cash counts, records, order tracking. The process that lives today in three files and in one person's head, turned into a system anyone on your team can use.

From $120,000 MXN + VAT

Web and mobile applications

For your team or for your customers. In the browser, with nothing to install, or as an iOS and Android app when it is really needed. A web app that works well on a phone costs less than a native app and is often enough.

From $250,000 MXN + VAT

MVPs for founders

The first product you can put in front of real customers and charge for. Scoped to what validates the idea and built to grow, not to be thrown away in six months.

From $120,000 MXN + VAT

Integrations and automation

Payments with Stripe, notifications by WhatsApp and email, and connections to what you already use. The task someone repeats every day, now done automatically.

How we work

  1. 01

    We start with the process, not the tool

    The conversation almost always starts with "we want an app" and ends somewhere else. Before talking about screens, we understand who does what, where the work gets stuck and what part of your business only one person knows how to do.

  2. 02

    The scope is put in writing

    What gets delivered, with a date, and what is not included. What makes a project expensive is not quality: it is changing direction halfway because nobody defined what would be delivered.

  3. 03

    Deliveries that get used

    Each stage arrives working, in the hands of the person who will use it every day. A well built system can be explained in an afternoon and used the next day.

  4. 04

    What happens after launch

    Who maintains it, how and on what timeline is defined before signing, not when something fails.

What we put in writing before signing

Five business questions, not technology questions. They get answered before signing or paid for later.

  • Who owns the code
  • Who owns the data
  • What gets delivered and by when
  • What is not included
  • Who maintains it afterward

What we have built and run

Not a portfolio of screenshots. These are products we designed, built and run ourselves, in production.

EventQR

RSVP management for weddings, quinceañeras and events. Guests confirm from a link without creating an account, the organizer sees the list live and on the day of the event people get in with a QR code. Paid per event with Stripe.

CuentaFácil

Management for restaurants: attendance with a photo from a kiosk, shifts, vacations, inventory and end of day cash counts, with WhatsApp notifications. Diners split the bill by scanning a QR code.

Conto

Personal finance for iOS. You log an expense by typing it the way you would say it, and the app understands it.

Frequently asked questions

How much does a custom system cost?
An internal system or web MVP starts at $120,000 MXN + VAT for the first module or process, in four to six weeks. A mobile app for iOS and Android starts at $250,000 MXN + VAT. Hosting and maintenance are separate. From there the price rises with how many processes it touches, how many people use it and what it has to connect to, which is why the proposal starts from a written scope. Be wary of a quote far cheaper than the rest: it is rarely the final price, it is the first of two payments.
Should I build custom software or buy a product that already exists?
If a product already does your process the way you do it, buy it: it is cheaper and already tested. Custom software makes sense when the way you operate is part of your advantage, or when you have spent years adapting your business to a tool that is not yours. We also build subscription products, so we can tell you from both sides.
Do I own the code and the data?
It is the first thing we put in writing, along with what gets delivered and by when, what is not included and who maintains it afterward. These are five questions any provider should answer before you sign.
Where do I start?
Write down how the process that hurts works today, even if it is three paragraphs, and send it to hello@stonework.io. That is enough for a first conversation.

What part of your business only one person knows how to do?

It is almost always the first process worth getting out of someone's head. Tell us which one.
