Custom Software Development for Plano Companies

Razoyo is a software engineering firm in The Colony, Plano's neighbor to the northwest, and we work on Central time. Since 2011 we have been taking the things companies built for themselves, the internal tool, the prototype, the spreadsheet that quietly became a system, and turning them into software the business can actually depend on.

We Are the Next City Over

Razoyo is in The Colony, Texas. The Colony is in Denton County, on Lewisville Lake, just northwest of Plano. Depending on which part of Plano you are in, that is a fifteen to thirty minute drive, and we work Central time either way.

Plano is one of the principal cities of the Dallas-Fort Worth metroplex and one of the densest concentrations of corporate technology in Texas. Toyota Motor North America and Frito-Lay North America are headquartered there, NTT Data's North American headquarters is at Legacy West, Samsung is moving its US headquarters to its existing Plano campus, and Verizon and JPMorganChase both have large operations in the city. That matters to us for one specific reason: companies of that kind generate an enormous amount of internal software that was never built to be software.

What Corporate Teams in Plano Usually Bring Us

Almost every project that starts here begins as something the company already built for itself.

A spreadsheet that has quietly become a system

It schedules, prices, allocates or forecasts something the business depends on. One person maintains it, it has no history and no permissions, and everyone is slightly afraid of it. Spreadsheets to a real platform.

An internal tool that outgrew the team that wrote it

Built by someone clever who has since moved on or moved up. It works, it is load-bearing, and nobody left can safely change it.

A prototype that now has to survive real users

Built in Lovable, Replit, Bolt, Cursor or Bubble, or by a small internal team. It demos well and it is not ready for customers, payments or scale. Prototype to production.

An internal tool other companies keep asking to buy

The strongest signal a product exists. Turning one company's internal system into something several companies can use is a specific piece of engineering, not a licensing decision.

Turning an Internal Tool Into Something Other Companies Can Use

This is a real engineering problem and it is consistently underestimated, because the tool already works. It works for one company, with one set of assumptions, and every one of those assumptions has to be found and removed. We have done this end to end: Matrix began as an internal hotel sales CRM built for a single organization, with performance that struggled under load, and we rebuilt it from the ground up into a multi-tenant SaaS product for M1 Intel.

What an internal tool assumes

One company's data, in one database, visible to everyone in it
Configuration that lives in someone's head or in the code
Your own team as the only users, and they can be trained
Downtime is an inconvenience, not a breach of contract

What a product has to do instead

Strict tenant isolation, so no customer can ever see another's data
Roles and permissions per customer, configurable without a deploy
Onboarding a new customer without an engineer
Uptime, support and a release process someone is accountable for

The honest first question is not how to build it. It is whether the demand is real and what it would cost, and that is what the $2,500 System Spec answers before you commit a budget. Read how we did it on Matrix.

What We Have Built

Published projects on this site, with real numbers.

An internal CRM that became a multi-tenant SaaS product

Matrix was an internal hotel event and group sales CRM, built for a single organization, with performance that struggled under load. We rebuilt it from the ground up on Elixir as a multi-tenant SaaS product for M1 Intel. Read the project.

A consultancy's internal reporting tool that became a market leader

Spider started as internal tooling delivering reports to revenue managers by email. We rebuilt it on Elixir and Phoenix into a self-service platform: re-indexing went from up to 24 hours to a few hours and then continuous updates, daily users from a few dozen to more than 10,000, and hosting costs fell by roughly 90%. Spider ranked #1 of 74 for Business Intelligence at the 2025 HotelTechAwards. Read the project.

We stay after launch

Six years on, we are still Spider's engineering team. Internal tools become products slowly, and the team that starts it should be the team that is still there for the second and third customer.

We will tell you when the answer is no

Not every internal tool should become a product, and not every prototype should be rebuilt. The Spec returns a build or do not build recommendation, and you keep it either way. How the Spec works.

What It Costs

We publish our prices, which most firms will not. The first two steps are fixed, so finding out whether your project is worth building costs a known amount before you commit to anything larger.

Frequently Asked Questions

We are in The Colony, Texas. The Colony is Plano's neighbor to the northwest, so depending on which part of Plano you are in it is roughly a fifteen to thirty minute drive. We work Central time, which in practice matters more than the drive: a question asked in the morning is usually answered the same morning.

Yes. Matrix started as exactly that, an internal hotel sales CRM built for one organization, and we rebuilt it into a multi-tenant SaaS product. What we establish first is whether the existing system should be extended or replaced, which is an engineering question with a real answer rather than a preference, and we will tell you to keep what you have when that is right.

Sometimes, and the fact that other companies are asking is the strongest signal there is. The engineering work is real: tenant isolation so no customer can see another's data, per-customer roles and configuration, onboarding that does not need an engineer, and a support and release process. Matrix went through exactly this, from an internal hotel sales CRM to a multi-tenant SaaS product for M1 Intel. The Spec tells you what it would cost before you commit.

Both. We have delivered for a Fortune 500 packaged goods brand and for founders with no software team at all. What stays the same is the shape of the engagement: a free consultation, then a fixed-price Spec that produces a real estimate, then a build you approve in stages rather than a single number agreed up front.

Yes, and in a corporate setting that is often the right shape. We can take a whole system, take one part of it, or work as a senior engineering layer over a team you keep. Dev Bursts at $1,200 a day or $4,500 a week exist for bounded pieces of work outside a retainer.

Once fees are paid, you own the code we write for you, and you can take the project to another team if you choose.

It depends on what you are building, which is why we do not quote a full build on a first call. What we can tell you up front: a consultation is free, a System Spec is $2,500 fixed, a Requirements Package is $2,500 fixed, a working MVP starts at $5,000 and a production build from $10,000. The Spec is there to turn "it depends" into a real number.
