Custom software development, from idea to operation
ASES develops tailor-made software for companies whose processes do not fit off-the-shelf programs: a web application, a customer portal, an app or an internal system. We also modernize existing software. Our own team handles custom software development, from the first conversation to support after the launch.

What software we develop
Custom software replaces the Excel sheet that has grown over the years, connects programs between which someone copies data today, and handles orders, approvals or calculations the way your team works. It takes one of these six forms, and many projects combine several, such as a customer portal with an app for your field staff.
Websites & CMS
A website that brings inquiries and that your team manages itself.

Custom software or standard software?
Custom software is developed for a specific company and its processes. Standard software is a finished program that many companies use in the same form and usually pay for by license. Standard software is quicker to roll out. Custom software handles your processes the way your team works and grows with your requirements.
Standard software is enough if…
- Data entryyour data is in one place and is entered once.
- Processesyour process matches what the program provides for.
- Licensesfew users work with it and the license costs stay manageable.
- Integrationthe program offers ready-made interfaces to your other systems.
- Your edgethe process is routine, such as accounting or email.
Custom software pays off if…
- Data entryyour team types the same data into several programs.
- Processesyour team shapes its work around the program's limits and keeps lists on the side.
- Licensesthe costs per user rise with every new employee, customer or location.
- Integrationyour systems do not exchange data and no ready-made integration closes the gap.
- Your edgeyour process sets you apart from the competition, for example in quoting, pricing or service.
Often your standard system stays in place, and we add custom software for the tasks it does not cover. The two then exchange their data through interfaces.
We recommend the solution that solves your task most simply. If a standard system is enough, we recommend it rather than custom development.
What custom software looks like in daily use
An order from inquiry to delivery, in sample software for a wholesaler. Every step that used to need an email, a list or a phone call runs here in one place and exchanges its data with your existing systems.
Choose a step to see what the software handles there.
Inquiry
From the customer portal, 12 line items imported.
BeforeForwarding emails and copying line items over by hand.
With your softwareInquiries from the customer portal, email or form land in one place, with customer and line items, without anyone typing them in.
Quote
Prices and discounts from the ERP.
BeforeA separate Excel sheet for pricing that only one person understands.
With your softwareThe software calculates with your prices, discounts and rules from the ERP and creates the quote as a PDF.
Approval
By the head of sales, with one click.
BeforeQuestions by phone and a signature on paper.
With your softwareAbove a threshold you set, the quote goes for approval. Who approved it and when stays traceable.
Delivery
Invoice created, customer notified.
BeforeDelivery note, invoice and customer email, each one separately.
With your softwareThe accepted quote becomes an order. The warehouse sees it immediately, the invoice is created on shipping, and the customer receives their shipping notification.
Your existing systems
ERP, accounting, CRM and email stay as they are. The software reads and writes their data through interfaces, so every system shows the same data.

Software development costs: what the price depends on
You know the price for your project before development begins. For the development, you pay a fixed price per project; for support, a flat monthly fee.
Quote
Development, one-off
Fixed-price project
- Fixed price for the precisely described scope
- If the scope changes, we adjust the quote first
- No billing by the hour
Launch
After the launch, monthly
Support and further development
- Flat monthly fee for maintenance and support
- Phone support around the clock
- New features per work package, each with its own quote
What the scope depends on
- How many work steps, special cases and approvals the software handles
- How many user roles with their own rights and views there are
- Which systems are connected, such as ERP, CRM, shop or accounting
- Whether the software runs in the browser, on iOS, on Android or everywhere
- In how many languages the user interface and content appear
- Whether data is carried over from a previous system
If you have a budget range, mention it in the initial consultation. We align the scope of the first version with it and plan further features for later steps.
Costs after the launch
Software keeps costing money after the launch as well: for licenses, hosting and maintenance. If it uses AI, you also pay for every request to the model. In the quote, we calculate these items over several years before you decide on a technology.
What you own at the end
After full payment, we hand over everything you need to run your software yourself or have it developed further by another team.
- Code
- The source code developed for you
- Git repository with the complete change history
- Technical documentation
- Design
- Design files of all screens
- Access
- Servers and hosting
- Domains
- Accounts for all services
- Rights
- Rights of use
We write code and documentation so that a new team can also find its way around. That way, you decide yourself who continues to look after your software.

Frequently asked questions about custom software development
Answers on costs, duration, rights, technology and security.
That depends on the scope: on the processes, user roles and platforms, and on the systems we connect. As soon as the scope is set, you receive a fixed-price quote for the project. We bill maintenance and support as a flat monthly fee, and we offer new work after the launch per work package. Tell us your budget range, and we will align the first version with it.
The duration depends on scope, integrations and platforms. Our own team starts promptly. If you have a fixed date, such as a trade fair or the end of a license agreement, mention it in the initial consultation. We take it into account when we plan the scope of the first version.
You do. After full payment, you receive the source code developed for you with the Git repository and the technical documentation, the design files, all access credentials for servers, domains and accounts and the rights of use.
No, an idea is enough. For the initial consultation, a short description of your project, the systems involved and what should be better afterwards is sufficient. We work out the requirements with you in the scope and quote phase. This results in a precisely described scope on which your fixed-price quote is based. We are happy to use an existing requirements specification as a basis.
Then we first adjust the quote and only then continue working. If a feature is added or something is dropped, you see beforehand what that means for scope and price. Because you see the prototype and the work in progress before anything goes live, new requests surface early.
Yes. We decide with you what belongs in the first version. Further features follow in the next steps. That way, your team or your customers work with the software early, and their feedback goes into further development.
That depends on where and how your users work. A web application runs in the browser on any device and is enough for many processes. As a progressive web app, it can also be placed on the home screen. If you need the camera, push notifications or a listing in the App Store, we develop an app, natively or with Flutter or React Native from one codebase for iOS and Android.
Yes, even if another provider built it. Depending on its condition, we develop the existing code further, connect the software with your other systems through interfaces or replace it step by step. We decide with you which path fits after we have looked at the code and data.
Yes. First we check which interfaces your systems offer, which data should flow automatically and which system is the source of truth for customer data and prices. Then we connect the new software, for example, with SAP or Odoo, with HubSpot or Salesforce and with your shop. After that, nobody has to type in orders and customer data anymore.
We do, on request, with updates, monitoring and further development. You talk to the team that built your software and knows it. If your own IT should take over parts of operations, we define the split together.
No. Our own team develops your software, from the first draft to ongoing support. As a software development agency, we have consulting, design, development and cloud in one team. That is why your project does not pass from firm to firm, and nobody has to explain it again.
By default, your software runs on servers in the EU, preferably in Germany. If we process personal data on your behalf, we conclude a DPA under Art. 28 GDPR. Who may see and change which data is governed by a role and permission model that we define with you. We transmit and store the data encrypted, back it up regularly and test the software for security vulnerabilities.
