Off-the-shelf software forces your company into someone else's workflows. Custom software maps your processes exactly - from ERP systems and RKSV-compliant POS solutions to automated invoicing. Built with enterprise experience from finance and POS systems with compliance requirements.
What is custom software?
Custom software is a solution developed exactly for the processes and requirements of one company - in contrast to standard software, which maps generic workflows for many users. It eliminates workarounds, duplicate data entry and licence costs for unused features.
Substance instead of slogans
ERP systems for SMEs
Order management, inventory, CRM, time tracking and invoicing in one system - tailored to your business instead of the industry average.
Financial compliance built in
Experience with RKSV-compliant POS systems, signature units, DEP export and interfaces to accounting systems such as BMD - compliance is part of the architecture, not an afterthought.
Process automation
Recurring workflows - quoting, dunning, reporting, data reconciliation - run automatically. Your employees work on the business, not on administration.
Interfaces & integrations
Connections to accounting, banks, POS systems, web shops, supplier APIs and legacy systems. Data flows automatically instead of via copy-paste.
Legacy system migration
Replacing Excel chaos, Access databases and outdated systems - step by step, without business interruption, with complete data migration.
Scalable architecture
Clean data models, documented APIs, maintainable code. Software that grows with the company instead of slowing it down.
Typical projects
- ERP and inventory management systems
- POS systems with RKSV compliance
- CRM and customer management systems
- Digital work reports & forms
- Automated invoicing and dunning processes
- API development & system integration
Technology stack
Proven standards instead of exotics: every technology in use has a large ecosystem and long-term maintainability - so your project can still be extended in five years.

Frequently asked questions about custom software
How much does custom software cost in Austria?
Custom software projects start at around €8,000 for focused single solutions; comprehensive ERP systems range from €20,000 to €80,000. The decisive factor is the feature scope - in the initial consultation the scope is precisely defined and a fixed price or agile budget is agreed.
Custom software or standard software - which is better?
Standard software pays off if your processes match the industry average. Custom software pays off as soon as you build workarounds, enter data twice or pay for unused modules. As a rule of thumb: from about 3 hours of manual process work per day, a custom solution usually pays for itself within 12 to 24 months.
Who owns the source code?
After full payment you receive the contractually agreed usage rights to the source code. You are not tied to Astra IT Solutions - a deliberate difference to many agencies that lock in customers long-term via code ownership.
How does an ERP project work?
In four phases: process analysis (1-2 weeks), concept & data model, iterative development with demos every two weeks, then migration and go-live with training. Details on the process page.
What happens after go-live?
You receive a warranty on all features and optionally a maintenance contract for updates, monitoring and further development. Critical bugs are fixed with priority even outside maintenance contracts.
