Custom Software Development
What is included in our "Custom Software Development" service?
Software that fits your processes – you don't have to adapt to the software.
Integration with invoicing, card payments, ERP and any external API.
Responsive web interfaces you can use in a browser, on any device.
Secure operation with permission management, audit logs and regular backups.
Automation and AI: less manual admin, faster turnaround.
Long-term hosting, support and further development, all from one team.
What is custom software development, and when does it pay off?
With custom software development, you don't bend your business to fit an off-the-shelf product – the software is built around your processes. You get exactly the features your company needs, and the system can grow as your business grows.
Custom software is worth considering when:
- day-to-day work happens across spreadsheets, emails and paper, and more and more time goes into copying data from one place to another,
- the software available on the market only half covers your processes, or you're paying for features you never use,
- you use several systems (invoicing, webshop, inventory, CRM) that don't talk to each other,
- the way you work is unique, and that is exactly your competitive advantage – something a generic product can't support,
- you're planning to launch a new digital service or SaaS product.
APPON has been building business systems since 2011. Our team has worked on more than 200 websites, as well as numerous web portals, business management and customer management systems, in sectors ranging from private healthcare to retail.
What kind of custom software do we build?
- Back-office and internal systems: work order, order, project and resource management, document registration, approval workflows.
- Customer portals and web applications: with registration, permission management, online booking and payment.
- System integrations: we connect your existing systems, for example with invoicing tools (Billingo, Számlázz.hu, Billzone), card payment gateways (OTP, SimplePay, K&H, CIB, PayPal) or healthcare systems (EESZT, the Hungarian national eHealth platform).
- Automation and AI: automatic SMS and email notifications, document generation, AI-powered summaries and customer service assistants.
- SaaS and MVP development: launching new digital products quickly, then improving them based on real user feedback.
Why APPON?
- We build on our own proven foundations: with Appon CMS and our business management modules we never start from zero, so development is faster and more predictable.
- We run our own products, too: the experience we've gained building SimpleSMS, Knowlio and Hostguard goes straight into your project.
- One team for everything: design, development, hosting, operations and support – no need to coordinate multiple suppliers.
- Responsible operations: since 2020 we have been working to run every system we host on a carbon-neutral basis.
A few of our completed projects: Healzz2, an administration system for private healthcare providers, patient call systems, the customer service system of Kocsiguru, and the I-Land online skills development platform. You'll find more of our work on our References page.
How we work
-
Discovery
We get to know how your company works, your current processes and where you lose the most time. Together we set the goals and priorities.
-
Specification and quote
We describe what the system will do and give you a detailed, itemised quote and a schedule. Where it makes sense, we start with a smaller first version (MVP).
-
Design and prototype
We show you in screen designs how the software will look and work, so changes are still easy to make before development starts.
-
Development in stages
We build the system in increments and regularly demo the finished features, so you can give feedback along the way.
-
Testing, handover and training
After thorough testing we put the system live, migrate your existing data and train your team.
-
Operations and further development
We take care of hosting, backups and updates, and keep developing the system as your company grows.
Eligible for EU-funded grants in Hungary
Programmes supporting the digitalisation of Hungarian SMEs (for example, subsidised digitalisation loan schemes) can also be used for custom software development. We'll help you find the right option for your company and prepare the quote you need for your application. You'll find the current opportunities on our Grants page (in Hungarian).
Frequently asked questions
How much does custom software cost?
The price depends mainly on the number of features, the integrations and the complexity of the user interfaces. After the discovery phase we give you a detailed, itemised quote. It's often worth starting with a smaller first version (MVP) and extending the system step by step.
How long does it take?
A small internal application can be ready in a few weeks, while a more complex system with several integrations takes several months. The I-Land learning platform, for example, was in live use roughly three months after development started.
Custom software or an off-the-shelf product – which should I choose?
If a ready-made product covers your processes well, it's usually the faster and cheaper option. Custom development pays off when the way you work differs from the norm, when several systems need to be connected, or when an off-the-shelf tool still leaves a lot of manual work. We'll tell you honestly during discovery which is the better choice.
Can you connect it to our existing systems?
Yes. We've built integrations with invoicing systems (Billingo, Számlázz.hu, Billzone, IMA ERP, Provimax), card payment providers (OTP, SimplePay, K&H, UniCredit, CIB, PayPal) and healthcare systems (EESZT). If a system has an API, it can almost certainly be connected.
What happens after handover?
If you wish, we run the system for you: we take care of hosting, backups, updates and bug fixes. New requirements are delivered as further development.
Is grant funding available for custom software?
For Hungarian companies, yes: programmes supporting SME digitalisation can typically be used for custom software development. You'll find the current opportunities on our Grants page (in Hungarian).
Is there a process you'd like to simplify with software?
Describe in a few sentences what's causing you trouble right now, and we'll show you how we'd solve it.
