When spreadsheets, email threads or an off-the-shelf tool can no longer carry the process, we engineer a web application that can: designed around your workflow, connected to the systems you already use and built to be maintained for years.
Core stack.NET / C# · ASP.NET Core · Angular · React · TypeScript · Microsoft Azure · SQL Server · REST APIs
Most of our web application work starts with one of these situations, not with a feature list.
If a well-configured SaaS product solves it, we'll tell you.
Building custom only makes sense when it fits your process better than what already exists.
Read: Buy vs BuildOrders, jobs or requests are tracked in shared sheets and forwarded emails. Nobody sees the real status without asking someone.
You pay for several SaaS products and still work around all of them, with the gaps filled by manual steps.
Every new feature takes longer than the last and the team is wary of touching older parts of the code.
Quotes, bookings, documents and status updates depend on someone replying to an email instead of self-service.
Pick one to see what it usually involves and how we typically build it.
Workflow tools, admin systems and operations apps that replace a spreadsheet-and-email process with one system your team works in every day.
Secure self-service for customers, dealers or partners, so quotes, bookings, documents and status updates no longer depend on someone replying to an email.
Platforms built around how your buyers actually browse and decide: catalogues, product discovery and enquiry flows, rather than a generic storefront template.
Installable web apps that feel native on phones and tablets, without building and maintaining separate mobile apps when a PWA is enough.
The APIs that let your web application talk to CRM, accounting, ERP, payment and email systems, so data is entered once and moves on its own.
Upgrading an application that has become slow or hard to change: framework upgrades, a UI/UX refresh and performance work, done in stages so the business keeps running.
Every engagement follows the same problem-first Systems Engineering Method we use across AppPotter.
We map how the work actually moves today: who does what, where it stalls and what the application must change.
We check whether existing tools can do the job before recommending custom work and say so if they can.
Screens and flows are designed around the people who will use them every day, then reviewed with you.
You see working software at agreed checkpoints, so priorities can shift before they become expensive.
Functional, cross-browser, performance and security checks before go-live, then a planned rollout.
The same team maintains, monitors and extends the application as the business changes.
We agree on what to measure during discovery, so success is defined before the build starts, not after launch.
Before: Status lives in spreadsheets and in people’s heads
After: One shared view of every order, job or request
Before: Data is re-typed from one tool into the next
After: Connected to your CRM, accounting or ERP, so data is entered once
Before: Customers wait on email for quotes and updates
After: Customers and partners serve themselves through a secure portal
Before: Every change needs a workaround
After: A maintainable codebase your business can keep extending
Before: Reports are assembled by hand each month
After: Reporting that reads from live data
Our depth is in the Microsoft .NET ecosystem with Angular or React on the front end, running on Azure or AWS. Where your existing systems or team point elsewhere, we work with that instead.
Where we have the deepest production experience
Also used when the project calls for it
Property management, lead handling and customer engagement running as three disconnected processes instead of one system.
For a focused, short-term engagement - an assessment, an architecture review, or technical due diligence - before any build begins.
For clearly-scoped integration or build work, where the outcome and boundaries are already well defined.
For long-term product or systems work - a sustained AppPotter engineering team working against your roadmap, not rotated project to project.
Whichever structure fits, Parth and Umesh are personally involved, from scoping the engagement to standing behind its outcome.
Meet our leadershipWe build custom only when an existing platform, integration or standard product can't solve the business problem. A web application is the most common form that work takes.
Still unsure? A 30-minute conversation usually answers the rest.
Book a callIf a well-configured SaaS product fits your process, that is usually faster and cheaper and we will say so. Custom makes sense when the workflow is specific to your business, when several tools need to work as one, or when off-the-shelf products force costly workarounds.
Yes. We start by reviewing the codebase and how it is used, then recommend whether to extend it, modernize it in stages, or replace specific parts. A full rewrite is rarely the first recommendation.
Our deepest experience is in .NET and ASP.NET Core with Angular or React, hosted on Azure or AWS. We choose the stack based on your existing systems and the team that will maintain it, not on our preferences.
Security is designed in from the start: secure authentication, role-based access, encrypted connections and security checks before launch. Specific compliance requirements are agreed during discovery.
It depends on how well-defined the scope is. Clearly scoped builds can be fixed price with milestones; evolving products usually suit a dedicated team or time and material. Most engagements start with a short assessment.
The same team can maintain, monitor and extend the application under an ongoing support arrangement, so knowledge of the system is not lost after go-live.
We'll look at how the process runs today and tell you honestly whether a custom web application is the right answer.
