Treevoxa offers software design consulting for businesses facing a decision that will be expensive to get wrong: whether to build or buy, how a new system should be structured, or what to do about software that has become slow, fragile or impossible to change. We are engineers who build and run our own products, so our advice comes from shipping software, not from slides. Software architecture consulting is part of every engagement.
Software consulting services: when they pay for themselves
- Before you build. A written specification and architecture stops a project from being quoted, built and argued about on assumptions.
- Before you buy. An honest comparison of ready products, configuration and a custom build, with the real costs of each over several years.
- When a project is stuck. An outside review of the code, the plan and the team's process, with a short list of what to fix first.
- Before you build an app. As an app consulting company, we tell you whether you need a native app, a React Native app or a fast mobile website. See mobile app development.
- Before an investment or acquisition. A technical review of a product's code, security and ability to scale.
What we deliver
| Engagement | What you get |
|---|---|
| Build-or-buy review | Options compared on fit, cost over three to five years, risk and time to launch, with a recommendation |
| Architecture and specification | Users and roles, data model, integrations, screens, non-functional needs and a phased plan |
| Code audit | Findings on security, structure, tests, dependencies, performance and deployment, ranked by risk |
| Advisory calls | A senior engineer on call for your team's design decisions |
What top software consulting companies should give you
A document you can act on with any team, not a sales pitch for their own build. Judge every consultant, including us, by that.
How we think about a system
We design business systems the way our own products work: one record for each real-world thing, every event posted once and reflected everywhere it matters, permissions that match real roles, and an audit trail for anything involving money. In Batchbook, one gate pass moves stock, posts to the client's ledger and updates the cost of goods, with nobody typing it twice. That principle saves more money than any framework choice.
Build or buy?
Our guide to custom software vs SaaS explains the deciding questions, and our comparison of custom ERP vs Odoo vs ERPNext shows how we weigh the options for one common decision. If one of our own systems fits, you can also buy it with its full source code and adapt it.
Technology consulting services: what we advise on
We are strongest where we build every day: Node.js (NestJS, Express), Python (FastAPI, Django), React and Next.js, React Native, PostgreSQL, REST APIs, payment and accounting integrations, and AI features built on the OpenAI and Anthropic APIs. See API development services for integration work.
How a consultation runs
- Brief. You send the decision you face and what you already know.
- Discovery sessions. We talk to the people who will use, pay for and maintain the system.
- Analysis. We review the options, the code or the requirements.
- Written recommendation. Delivered as a document, then walked through on a call.
- Your choice. Build with us, with another team, or buy. The document works for any of them.
Engagement models and cost
Consulting is priced as a fixed fee for a defined deliverable, or hourly for advisory work, agreed in writing and in US dollars before it starts. If you then build with us, the specification becomes the scope of the project, so the work is not repeated. For project pricing in general, see our custom software development cost guide.
What to send us for a consulting quote
The decision you face, what you already know, any existing specifications or code, and the date you need an answer by. For a code audit, read access to the repository and a short description of how it is deployed.
Working across time zones on consulting projects
Discovery sessions are scheduled inside your working hours, usually your morning for US teams and the afternoon for UK and European teams. Written work happens around them.
