Custom software development for Missouri businesses
Sentinel Web Systems builds custom software for businesses that need more than a brochure website. From customer portals and booking systems to internal dashboards and connected business tools, we help turn a manual process or product idea into a web application. We are based in Poplar Bluff, Missouri and work with clients remotely throughout the United States.
Discuss your project
Start with the problem, then define the software
Tell us who will use the system, what they need to do, and where your current process breaks down. Examples include collecting customer requests, tracking work across a team, managing bookings, or moving information between systems. We use those requirements to define a practical first version and separate essential functionality from future additions.
Web applications, portals, and internal tools
A customer portal can give clients a place to submit information and follow progress. An internal dashboard can bring records and tasks into one place. A booking application can coordinate appointments and related business steps. The appropriate features depend on your users, data, permissions, and existing tools; these examples are project options, not prepackaged claims about completed client work.
Connect the frontend to a useful backend
Custom software often needs data storage, user roles, server-side business rules, payments, or external integrations. We scope these together so the interface and the system behind it support the same workflow. For projects involving an existing product, an initial review helps identify which parts can be reused and which need further work.
Scope, pricing, and handoff
Custom software is project quoted; the published development rate is $125 per hour. A useful project brief includes the goal, users, required features, integrations, budget, and desired timing. Before work begins, agree on deliverables, acceptance criteria, deployment responsibilities, access handoff, and support needs. Third-party services may have separate costs.
