Custom software development

Sydeso builds your booking platform, client portal, Admin dashboard, SaaS product, AI application or internal tools.

We are a senior software engineering team dedicated to supporting busy, non-technical founders and business owners who need custom software built for their operations. We work with you from idea all the way to launch.

A concept invoice approval app: a list of subcontractor invoices beside one invoice with extracted line items, two lines flagged above the contract rate
Concept by Sydeso: AI reads each invoice and flags lines above the contract rate, and a manager makes the call.

Sydeso is a Texas based company with over 25 years of combined experience. After launch, we stay engaged for continuous implementation and product improvement.

Concept work

Three concepts Sydeso built to show what your software could look like.

Each one is a working page you can click through, with made-up data. They are examples, not client projects.

Who we work with

For owners who would rather run the business than manage developers.

You run the company and Sydeso runs the engineering. Simply review our progress updates, give us your feedback, handle the important business decisions, and we take care of the rest.

  • You have an idea and no engineering team.

    Founders and small teams hire us to go from sketch to a live product. Most fixed-scope MVPs take 10 to 14 weeks to launch.

    MVP development

  • Your business runs on outdated tools, systems, and processes.

    Internal tools, portals and integrations built around how your people really work, so you can modernize your workforce.

    Internal tools

  • You want to reliably integrate AI in your product.

    Agents that draft, sort and triage inside your software, with limits you approve and a person checking what they produce.

What we build

Every project leaves you with working software and the documents to run it.

A concept dispatch board: technicians in columns, today’s jobs as cards in time slots, and a queue of unassigned jobs
Concept by Sydeso: the dispatch spreadsheet, rebuilt as one screen the whole office can work from.

Before you hire anyone

Ask these four questions before you hire any software agency.

Get every answer in writing. These are Sydeso’s.

Who owns the code when the project ends?
You do. The code, the repositories, the data structures and the designs belong to your company when you accept and pay for the final milestone.
What is the most I can be billed?
The number on the written estimate. On hourly work, the cap is the most Sydeso bills without your signature. On a fixed price, Sydeso carries the risk of the hours.
When do I see the work?
From the first week of development. You get read-only access to the project board and the staging site, and you test every feature yourself before it ships.
What happens after launch?
Sydeso stays on to monitor the software and ship new features, most of them within 1 to 2 weeks. Or you take everything in-house; it is already yours.

How we work

How a Sydeso project runs, from the first call to launch day.

  1. 01

    We work out what to build.

    Discovery, then a requirements document you can read and argue with. You review the scope and the design before we write any code.

  2. 02

    We build it and break it.

    Development, then QA testing, then UAT, where you test it yourself. Most MVPs take 10 to 14 weeks from the first call to launch.

  3. 03

    We launch it and keep going.

    We deploy it, monitor it and ship what comes next. Most new features go live 1 to 2 weeks after the MVP, depending on how complex they are.

The seven phases

  1. 01 Discovery Interviews, goals, open questions
  2. 02 Scoping and PRD Requirements, scope, estimate
  3. 03 Design and data Screens, flows, data model You approve the design
  4. 04 Development Build, review, document
  5. 05 QA testing Verify, break it, report
  6. 06 UAT You test, you report You accept the result
  7. 07 Deployment Launch, monitor, support
