Types of desktop applications we develop

The right desktop application depends on the problem you're solving. These are the main types we build, from internal tools to hardware-connected systems.

Internal business tools

Custom desktop applications shaped around the way your team actually works. We design for the daily realities of data entry, approvals, reporting, and internal dashboards, so the software fits how the work already gets done.

ERP, CRM, and WMS desktop applications

Desktop apps for ERP, CRM, and WMS workflows, where speed and reliability matter as much as features. Native performance, deep integration, and the fast keyboard-driven entry that power users rely on.

Data processing and reporting tools

Tools for working through large datasets, running calculations, and generating reports without the limits of a browser. Local processing moves through millions of records quickly, with exports to the formats and pipelines your team already uses.

Hardware-connected desktop applications

Desktop software that talks to scanners, sensors, instruments, and other connected devices. We handle the drivers, protocols, and integration testing, so the hardware and software behave predictably in production.

Client-server desktop applications

Desktop clients connected to SQL Server, cloud backends, or internal systems with secure two-way sync. They combine local speed, centralized data control, and offline-tolerant access.

Legacy desktop applications

Older desktop applications refactored, rebuilt, or moved onto a modern framework. We keep the business logic that already works and bring the interface, performance, and security up to current standards, so the tool stays useful for years more.

Signs your business needs desktop application development

Some situations call for a desktop application specifically. These are the ones that bring most teams to us.

Complex internal workflows

When daily work runs through multiple screens, layered business rules, and steps that depend on what came before, a desktop application keeps things fast and predictable. Native speed and full keyboard control matter when staff are in the tool for hours.

Offline or local network access

For teams in places where the connection is limited or unreliable, a desktop application keeps working without it. Data syncs back to the server once the network returns, so nothing stalls while people wait to reconnect.

Hardware and device integration

When the software has to read from connected devices — scanners, instruments, sensors, point-of-sale units — native desktop access gives a stable bridge to the hardware. Browser security models often block this kind of direct communication.

Outdated legacy software

Aging desktop tools that still run the business and keep costing more in workarounds, bugs, and support over time. Legacy app modernization keeps the workflows your team knows while moving the underlying stack to something supportable.

High-performance data processing

Working through millions of records, running heavy calculations, or building reports off large local datasets. Desktop applications handle this without browser memory ceilings or the overhead of constant network round-trips. Local processing power carries the load.

Integration with existing business systems

Connecting to your ERP, CRM, accounting software, or existing databases through native APIs and protocols. A desktop application integrates at the system level, with direct access to local files, network shares, and printers that browser-based tools usually can't reach.

Stages

Our desktop app development process

Our development processes run from discovery to deployment, with clear communication at each stage. Every step ends with something you can review before we move on.

01
Discovery
We start by learning how your business runs today. Stakeholder conversations, a review of the current workflow and customer touchpoints, and the technical context all shape the project's scope.
02
Requirements analysis
We write down detailed project requirements — what the application has to do, what it connects to, and which edge cases matter. The result is a clear technical specification everyone signs off on.
03
Architecture planning
Project planning and architecture decisions that account for performance, security, future growth, and the systems the application will run alongside. Choices that are cheap to change now and expensive later get made here.
04
UI/UX design
User experience design built around the tasks your team performs most. Wireframes and clickable prototypes go through rounds of structured user feedback until the interface matches the real work.
05
Desktop application development
Backend coding, interface work, and integrations move forward in iterations, with regular demos so progress stays visible. Code stays clean, tested, and documented as each piece is completed.
06
QA testing
Quality assurance covers functional logic, performance, security, and integration scenarios. Problems surface early through automated checks, manual review, and acceptance testing against the requirements set at the start.
07
Deployment and support
Packaging, rollout planning, and the deployment approach that suits your IT setup. After launch, we stay on for fixes, updates, and the improvements that come up as the business grows.

Our partnership with Asabix has been in place for 5 years, and its been a successful collaboration. We sought their expertise based on recommendations we received to finalize our existing online store and eventually develop a new, more technically advanced one that supports two languages and currencies for international shoppers. The outcome was perfect for us: the Laravel-based online store loaded quickly and displayed perfectly on mobile devices. Its worth mentioning that we frequently incorporate third-party services or follow specific recommendations from SEO agencies, and Asabix handled it all, saving us from unnecessary back-and-forth. This team helped us bring Ukrainian hospitality online and draw in new customers.

We’ve been working with the Asabix team since 2018 on developing and improving our SkladUSA system, and overall it’s been a very solid experience.

We run cross-border logistics, fulfillment, tracking, integrations, and a lot of moving parts. The system had to support real operational complexity.

Communication has been consistent, deadlines are generally respected, and when issues come up (because in tech they always do), they stay involved until things are resolved.

The SkladUSA system continues to evolve, and Asabix has been a reliable partner in that growth.

We hired Asabix to develop a website that would rank highly in search engines and have an up-to-date look. We needed to present our furniture series and collections online for many European countries. Our communication with the Asabix team was quick and straightforward, and the outcome was even better than we imagined: the website works flawlessly, and we also introduced loyalty programs and promotional subscriptions. The admin panel we received was user-friendly, allowing us to manage and launch the online store on time.

Frequently Asked Questions

What is desktop application development?

Desktop application development is the process of building software that is installed and runs locally, the way Excel or a POS terminal does. We build them for Windows, macOS, and Linux. Teams usually go with a desktop app for three reasons: real performance, reliable use when the connection drops, and a direct line to hardware like scanners or lab equipment.

How long does desktop app development take?

The timeline depends on the scope. Small, single-purpose tools we've delivered in three or four months. Larger applications that require several integrations and complex business logic tend to take around six to nine months before they're stable enough for real users.

How much does desktop application development cost?

Price depends on the scope and complexity of the application. A small, single-purpose tool can be built relatively quickly. Once you add several integrations, hardware support, or custom reporting, the effort grows. The most accurate estimate comes after a short scoping call, where we define what the application should do, which systems it should connect to, and what level of functionality you need.

Can you build desktop applications for Windows, macOS, and Linux?

Yes, we work with all three. Either a separate native build per platform or one shared codebase covering Windows, macOS, and Linux through a cross-platform framework. We decide based on how much native performance you need and how closely the app has to integrate with each system.

How can desktop application development help reduce manual work and operational errors?

Mainly by removing the manual steps where mistakes tend to happen. Re-keying data between systems, copying figures across spreadsheets, and similar repetitive work. The application handles those, validates entries as they're made, and keeps the whole team working from the same data.

How do you ensure desktop application security and data protection?

Security is built in at the foundation. The baseline comes first: security protocols, encrypted audit trails, encrypted backend connections, and whatever specific controls your compliance team requires.

Do you provide maintenance and support after launch?

Yes, after launch, we handle bug fixes, OS updates, security patches, and new features as they come up. Many clients stay on a retainer, so someone who already knows the codebase is available the next time something needs changing.
