How much does custom software cost in Mexico in 2026?

What the market charges in 2026

Nobody publishes an official price for custom software. What exists are the ranges that Mexican providers publish in their own guides. Use them as a reference, not as independent data. All amounts are in Mexican pesos (MXN).

Almost none of these guides say whether their ranges include VAT. Assume they don't. Software development is subject to 16% VAT (IVA), so a $120,000 system costs you $139,200.

Why the same system can cost five times more

When two quotes for "the same system" differ fivefold, they are almost never quoting the same thing. These are the things that move the price most:

1. How many processes it covers. Orders and inventory are two processes, not one. Each process brings its own screens, rules and reports.
2. How many roles use it. A salesperson, the warehouse and the owner see different things. Each role adds permissions that have to be built and tested.
3. What it connects to. Electronic invoicing (CFDI, the Mexican electronic invoice), card payments, WhatsApp notifications or your accounting system. Each connection is work of its own.
4. Whether data has to be migrated. Moving ten years of Excel files into a system means cleaning them before you import.
5. Whether it is an app or a web system. An app for iPhone and Android goes through the app stores and costs more than a web system that works well on a phone.
6. Who builds it. For a first phase, Fuera de la Caja puts a freelance developer at $40,000 to $90,000, an agency at $100,000 to $150,000 and a large consultancy at $250,000 to $600,000 or more.
7. How much certainty you are buying. An estimate made before anyone understands the process can be off by a factor of four, high or low, according to the cone of uncertainty from Construx. Whoever quotes low without a diagnosis is placing a bet, and you pay for it.

What it costs to do it with your own team

To compare, it helps to know what a developer on payroll costs:

• A senior developer in Mexico earns a median gross salary of $106,000 a month (Talentosy, November 2026).
• With benefits and employer contributions, the company pays 35% to 45% more (Axented, March 2026).
• That comes to $143,000 to $154,000 a month, before recruiting and before anyone reviews their work.

An in house team makes sense when software is your business and you will be developing all year. For a first system, commissioning it usually costs less than hiring.

What the quote almost never includes

• VAT. Always ask whether the price includes it.
• What it costs to run the system each month. Hosting, database, email, WhatsApp messages, invoice stamping fees and a domain. A small internal system pays on the order of $1,500 a month in third party services.
• Maintenance. Providers such as MeepLab recommend setting aside 15% to 25% of the initial cost each year. We found no study that backs that figure. We did find that over its life, software spends 40% to 80% of its total cost on maintenance (Robert Glass).
• Your team's time. Someone has to explain the process, test each delivery and clean up the data.

What the first year costs: an example

Illustrative example, not a quote. A distributor wants to move its orders and inventory out of Excel. Ten people will use the system.

If the process grows (more branches, invoicing, an app for delivery drivers), each stage is quoted separately and added on.

When custom software is not worth paying for

If a program already exists that handles your process the way you run it, buy it. Martin Fowler calls this utility software: it solves what every business needs and does not set you apart from anyone, like payroll. Accounting and invoicing fall under the same idea.

For example, Alegra publishes invoicing plans from $249 to $699 a month plus VAT, with unlimited invoices. Paying $120,000 to replicate that makes no sense.

Building pays off when the way you operate is part of your edge, when a subscription product forces you to keep a separate Excel file on the side, or when you need to bring together things that no package combines.

How to ask for a quote you can use

Before you ask for a price, write one page on how the process that hurts works today: who enters what, in which file and where things get stuck. With that, any serious provider can give you a range in the first conversation.

Ask for a proposal that splits development into stages, says what it does not include, estimates the monthly cost of running the system and states who owns the code and the accounts. If it doesn't say, ask: who owns the code?
