Application development consulting is expert advice on building, buying, modernizing or rescuing software. Inventh reviews architecture, code, security and delivery plans, compares build and buy options on total cost of ownership, and gives an honest recommendation, including when a project should change course.

Application Development Consulting
Our approach
The most expensive software decisions are made before the first line of code.
Choosing the wrong platform, architecture or partner can cost years. We bring senior architects and delivery leads who have built and supported applications, and who will tell you plainly what they would do in your place.
Decisions backed by evidence
Every recommendation compares real options on cost, risk, time and fit, not on fashion or preference.
Architecture that lasts
Designs that meet today’s needs, keep options open and avoid lock in you will regret.
Independent of the build
Our advice stands on its own, whether we build the application, your team does or another partner does.
Where we help
The moments that need an experienced view
Application consulting pays for itself at a few critical points in the life of a system.
Starting a new application
Requirements, architecture, technology stack and delivery plan agreed before development starts.
A realistic budget and timeline, and fewer surprises.
Build or buy
Custom development, packaged software and low code options compared on total cost and fit.
The right approach, with the numbers to defend it.
Ageing applications
Legacy systems assessed for risk, cost and business value, with modernization options.
A staged plan instead of a risky big bang rewrite.
A project in trouble
Independent review of scope, code, team and plan when delivery is late or over budget.
A clear recovery plan, or an honest recommendation to stop.
Acquiring or inheriting code
Technical due diligence on code quality, security, architecture and team.
Known risks and costs before you commit.
Scaling a product
Performance, reliability and cost reviews as users, data and features grow.
An architecture ready for the next stage of growth.
What we deliver
Our application development consulting services
Senior advice at the points where it changes outcomes, delivered as focused engagements.
Solution Architecture
Target architecture, integration design, data model and non functional requirements for new or changing applications.
Build or Buy Assessment
An objective comparison of custom development, packaged software and low code platforms, with total cost of ownership.

Delivery Assurance and Project Rescue
Independent oversight of projects in flight, and recovery plans for projects that are late or over budget.
AI in your applications
Designing applications for the AI era
Every new application should be ready for AI features, and many existing ones can gain from them. We help you decide where AI belongs and how to build it in safely.
AI feature assessment
Which AI capabilities, such as assistants, search, document processing or prediction, add real value to your application.
AI ready architecture
Data access, APIs, security and monitoring designed so AI features can be added without rework.
AI assisted development
Guidance on using AI coding tools productively while protecting code quality, security and intellectual property.
Agent ready integration
APIs and open standards such as the Model Context Protocol that let AI agents work with your systems safely.
Our consulting framework
From question to a decision you can defend
A structured approach that turns a complex technology choice into a clear, evidence based recommendation.
Understand
Business goals, users, constraints, existing systems and the decision that needs to be made.
Analyze
Options assessed on fit, cost, risk, time and support, with code and architecture reviewed where relevant.
Recommend
A clear recommendation, the reasoning behind it and the trade offs of the alternatives.
Enable delivery
Architecture, specifications and a plan that your team, our team or another partner can deliver.
Recommendations reference OWASP guidance, WCAG 2.2 and current platform support schedules.

FAQ
Frequently asked questions
What is application development consulting?
Application development consulting is expert advice on building, buying, modernizing or rescuing software applications, covering architecture, technology choices, delivery plans and independent reviews of code and projects.
Should we build custom software or buy a packaged product?
Buy when your process is standard and a product fits most of it. Build when the process differentiates your business or integrations are complex. We compare both on total cost of ownership before you decide.
What does a code audit include?
A review of code quality, architecture, security, dependencies, test coverage and documentation, with findings ranked by risk and effort to fix.
Our software project is late and over budget. Can you help?
Yes. We review scope, code, team and plan independently, identify the root causes and recommend a realistic recovery plan, or an honest case for changing course.
How do you choose a technology stack?
We match frameworks and platforms to your requirements, team skills, hosting and support horizon, favoring proven, well supported technologies over fashion.
Can you do technical due diligence before an acquisition or investment?
Yes. We assess code quality, security, architecture, scalability and the team, and report the risks and likely costs before you commit.
Do we have to use Inventh to build the application?
No. Our consulting stands on its own. Your team, our engineers or another partner can deliver the plan.
How long does an application consulting engagement take?
A focused application review or build or buy assessment typically takes a few weeks. Architecture and planning for larger systems takes longer.
