Why Build a Custom Web Application Instead of Another SaaS?
If an existing SaaS product covers your need at a subscription you're happy with, use it. When you'd have to bend the SaaS to fit your business, custom software usually costs less over time and fits better.
What a custom application gives you
- Automated manual processes
- Lower operating costs
- More accurate data
- More productive employees
- A better customer experience
- Real-time visibility into operations
- Software that scales with the business
When custom software makes sense
- Your processes are unique
- Existing software forces workarounds
- Employees keep data in several systems
- Integration requirements are complex
- Competitive differentiation matters
- You need control over your own roadmap
Not sure which way to go?
Web Application Architecture That Fits How Your Users Work
A web application is software your users sign into through a browser to get work done, such as approving orders, bidding on RFQs or tracking patients, rather than a website they read. It runs on any device without installing anything and connects to the systems behind it, such as your ERP or CRM. We pick the architecture from how your application will be used: who signs in, on what devices, how much data they work with, and which systems it has to talk to.
Single-page applications (SPA)
Angular or React front ends on ASP.NET Core Web APIs. Screens update without page reloads, so portals and data-heavy internal tools feel like desktop software.
Best for: portals, dashboards, line-of-business apps.
Progressive web apps (PWA)
One application that runs in the browser and installs on tablets, phones and PCs like an app, without app-store releases.
Example: Graham Healthcare Group's Clinician Hub, a PWA for secure messaging and video visits.
API-first integration
Every feature sits behind a documented REST API, so your ERP, CRM, mobile apps and future systems can use the same data and rules.
Example: TKS suppliers bid in a supplier portal connected to the purchasing system.
Cloud hosting on Azure or AWS
We deploy to Microsoft Azure or Amazon Web Services and set up hosting, databases, storage and sign-in to suit your security and budget.
Example: the TKS custom ERP runs on AWS; Graham's Clinician Hub on Azure.
Performance targets agreed up front
We recommend most pages render within 3 seconds and write the target into the requirements, then design the database and APIs to meet it.
Example: Full Throttle's customer portal answers in under a second.
Responsive on every screen
Layouts adapt to desktop, tablet and phone, so office staff, field teams and customers use the same application.
Need a native app too? See mobile app development.
Enterprise Web Application Development Standards
Every application we deliver meets the same standards, whether it's a startup's first release or an enterprise system. These are the questions IT teams ask us most, answered up front.
Easy to use from day one
- Wireframes approved by your users before coding starts

How Long Does Web Application Development Take, and What Does It Cost?
Every project is estimated after discovery, but these are typical ranges for the web applications we build.
| Item | Typical scope | Timeline | Starting at |
|---|---|---|---|
| MVP or first product release | Core workflows for the first users, sign-in, an admin area, one integration | 2–4 months | $30,000 |
| Customer, supplier or partner portal | Secure sign-in, self-service requests, documents, notifications, 1–2 integrations | 3–5 months | $45,000 |
| Internal business application | Replaces spreadsheets and email: workflows, approvals, dashboards, reports | 3–6 months | $45,000 |
| Enterprise application or custom ERP | Several modules, SSO, multiple integrations, released one module at a time | 6–12+ months | $90,000 |
| Modernizing an existing web application | Moving PHP, VB, jQuery or older .NET apps to modern .NET and Angular, in stages | After assessment | After assessment |
Prices are for projects delivered by our Michigan team. Your firm estimate comes out of discovery, priced as fixed price, milestone-based or hourly. Example: Full Throttle's customer support portal was delivered in under 3 months, on budget. What moves the price most: the number of integrations, user roles, data to migrate and compliance requirements.
Fixed price
For a well-defined scope. You know the total before we start, and changes go through an agreed change request.Milestone-based
For larger builds. You pay as each agreed milestone is delivered and accepted.Hourly

Web Application Development FAQs
How much does custom web application development cost?
It depends on scope. Most of our custom web application projects start at around $30,000, and larger systems cost more; see the typical ranges by project type above. We give a firm estimate after discovery, priced as fixed price, milestone-based or hourly.
How long does development take?
An MVP or first release usually takes 2–4 months, a customer, supplier or partner portal 3–5 months, an internal business application 3–6 months, and an enterprise application 6–12 months or more, released module by module. Full Throttle's customer portal was delivered in under 3 months. We give you a firm timeline after discovery.
What do I get from discovery?
A requirements document (or a clear list of what's in and out of scope), an estimate priced as fixed price, milestones or hourly, and a high-level project plan with milestones and release dates. Wireframes of the main screens follow in the next step, before any code is written.
What is a web application?
Software your users sign into through a browser to get work done, such as approving orders, submitting bids or tracking patients. Unlike a website, which people read, a web application stores and processes your data, runs on any device without installing anything, and connects to the systems behind it, such as your ERP or CRM.
Do you build single-page applications or progressive web apps?
Both. We build SPAs with Angular or React for portals and data-heavy business tools, and PWAs when users need to install the application on tablets, phones or PCs without going through an app store.
Where will my web application be hosted?
On Microsoft Azure or Amazon Web Services. We set up hosting, databases, storage, monitoring and backups, with separate environments for development, QA, staging and production.
Will my web application be accessible and ADA compliant?
We run Lighthouse accessibility audits on every release and fix the issues they find, such as color contrast, form labels, alt text and keyboard navigation. When your project must meet ADA or Section 508 requirements, we build and test to WCAG 2.1 AA.
Are you a Michigan web application development company?
Yes. SharpQuest has been headquartered in Troy, Michigan since 2009, and a project lead in our Troy office runs every project. We work with businesses across the US, including Michigan clients such as TKS Industrial, American MSC, Plastic Omnium and the Michigan Economic Development Corporation (MEDC).
Who owns the source code?
Ownership of the code and other work is set out in your contract, and we agree it with you before work starts. At handover you get the source code, documentation and environment access your contract covers.
How do you keep our web application and data secure?
Security is built in from the start. We follow secure development practices based on the OWASP Top 10, use role-based access, audit trails and encryption in transit and at rest, and support single sign-on with Microsoft Entra ID. We sign HIPAA BAAs for healthcare projects and carry professional liability (E&O) insurance.
Can you work alongside our in-house developers?
Yes. We follow your coding standards, tools and release process, work in your Azure DevOps or repositories if you prefer, and document and hand over what we build. If you only need extra developers, see IT staff augmentation.
Will you sign an NDA before we share our idea?
Yes. We sign your NDA, or use our own, before you share any confidential details about your idea or your business.
Should I build custom software or buy SaaS?
If an existing SaaS product meets your need and the subscription cost works for you, use it. If you'd have to customize the SaaS heavily to fit your business, building custom software is usually the better choice.
Can you integrate with Dynamics 365 Sales?
Yes. We build custom applications that integrate with Dynamics 365 Sales through its APIs, or we extend Dynamics 365 Sales itself with server-side extensions, client-side scripting or Azure Functions.
Can you modernize our existing application?
Yes. We modernize applications written in PHP, VB, older versions of .NET and jQuery. See our application modernization services for details.
Do you provide post-launch support?
Yes. We offer monthly support plans: Essential (10 hours, response within 2 business days), Professional (20 hours, next business day) and Premium (40 hours, same day during business hours, highest priority). Some clients have stayed with us for up to 8 years.
Can AI be integrated into our application?
Yes, if we have the source code, or if the application is a well-known platform (such as an ERP) that allows customization. See our AI integration services.
What technologies do you use?
Mainly Microsoft .NET and C#, plus Node.js, Angular and React, on Azure or AWS, with SQL Server, Oracle, PostgreSQL or MySQL.
Can you build an MVP for my startup?
Yes. We help founders define a focused MVP scope, build the first version, gather feedback and scale the platform as it grows.
