What counts as a web application
A web application is software that lives in the browser and replaces work that used to happen in spreadsheets, paper, phone calls, or a SaaS product that almost-but-not-quite fits. It is what a Hays business uses every day to run the operation — not the public marketing site that brings in new buyers.
Common examples in Hays: a dispatch tool that assigns tickets to crews, a portal where customers see their job history and pay invoices, an admin app where the back office approves estimates, a real-time dashboard that pulls KPIs from five different systems into one view. The work happens inside the browser; the team logs in and the application does its job.
Preisser Solutions builds these applications custom — not assembled from off-the-shelf parts. The result is a system that fits the way the business actually runs and grows with it instead of fighting it.
Tools we build for Kansas SMBs
Most Hays and western Kansas web app projects fall into a handful of patterns. Many engagements ship two or three of these working together so the team stops jumping between products:
- Internal admin tools — the daily workspace for dispatch, scheduling, approvals, data entry, audit trails, and recurring back-office tasks
- Customer portals — secure logins where clients submit requests, exchange documents, see job status, and pay invoices
- Custom CRMs — pipeline, contact, and activity tracking built around the actual sales process, not what HubSpot or Salesforce assume the process is
- Inventory and operations systems — real-time tracking of materials, transfers, counts, and pricing markups across yards or job sites
- Operational dashboards — live KPIs pulled from QuickBooks, the field service platform, the phone system, and other source systems
- AI applications — chat, search, drafting, classification, invoice extraction, and decision support embedded inside the custom app with access to the business's own data
How we scope and ship
Custom web applications have a reputation for being expensive, slow, and risky to commission. Preisser Solutions runs projects with that reputation in mind — fixed-price scopes, phased delivery, and a written plan before any code is written.
Every Hays engagement follows the same shape:
- Free scoping call — in person in Hays, on site at the operation when it helps, or by video for clients further out
- Written proposal — fixed scope, fixed price, fixed timeline, and a clear definition of done before kickoff
- Phase 1 build — the smallest version of the app that delivers real value, usually shipped in 8 to 12 weeks
- Use in production — the team uses Phase 1 every day before Phase 2 gets built, so the next phase adapts to what is actually needed
- Phase 2 and beyond — additional features, integrations, and AI layered in once the foundation is proven in use
- Code ownership — the source code is delivered to the client with documentation written for the team, not for other developers
Industries served
The web applications Preisser Solutions builds are vertical-aware. The dispatch tool for an HVAC company looks different from the inventory system for an oilfield services operator, which looks different from the patient-intake portal for a clinic. The same engineering principles apply, but the workflows are specific to each industry:
- HVAC and home services — dispatch, recurring maintenance plans, on-call rotations, financing workflow, and emergency call routing
- Oilfield services and energy — yard inventory, transfer tracking, AI invoice processing (HG Oil Holdings cut back-office time by 95%), and field operator dashboards
- Medical and dental clinics — patient intake, scheduling overflow, internal task routing, and integrations with practice management systems
- Professional services — law, accounting, and insurance firms that need matter management, document portals, and recurring client workflows
- Agricultural businesses — feedlots, custom harvesters, ag retail operations, and equipment dealers that need to track jobs, contracts, and seasonal capacity
- Construction and trades — bidding, change orders, subcontractor coordination, job costing, and field photo capture
Why custom over off-the-shelf
Most Hays businesses arrive at custom web applications after a long detour through SaaS. The first SaaS product solves part of the problem. The second SaaS product solves a different part. By the time the business is paying for five SaaS subscriptions and the team is re-entering the same data into each one, the math tips toward custom.
The case for custom is operational, not philosophical:
- SaaS subscriptions climb every renewal and never get cheaper at scale
- SaaS products own your data and limit how it can be queried, joined, or moved
- SaaS workflows almost-but-not-quite fit, and the workaround eventually stops getting followed
- Custom code can connect cleanly to the SaaS products that do still earn their keep — accounting, payroll, payments — without forcing every workflow through them
- AI features that have access to the business's own data are only possible inside custom systems, not as bolt-ons to existing SaaS products
- Source code ownership means there is no vendor that can sunset the feature, raise the price, or get acquired and change direction next year
