Deltologic - Custom Software Development Services

Software to solve all business needs

In our custom software development services, we bring a personal touch to every project across these key areas:

  • Building tools for Sellers and Vendors is designed to tackle the specific challenges they face in online marketplaces. This service involves linking data from various platforms, streamlining repetitive tasks, and creating custom software that meets individual business requirements. The goal is to make operations more efficient, cut down on manual work, and provide valuable data insights for better decision-making. This strategy turns technology into a valuable tool, helping sellers improve their business operations and growth.
  • Building SaaS tools involves improving and regularly updating existing software-as-a-service platforms, as well as creating new ones. This service includes constant support and maintenance to keep SaaS products up-to-date and running smoothly. It also focuses on upgrading current tools to better their performance and make them more user-friendly. For new SaaS projects, the goal is to turn innovative ideas into practical solutions that are ready for the market, similar to how a building is carefully constructed with a strong foundation and detailed design to meet various user needs.
  • Creating custom software for Agencies is all about making their work in online marketplaces more efficient and helping them grow. Deltologic provides technology solutions that streamline how agencies operate, making sure they work well with tools agencies already use, like Jungle Scout and Helium10. They're skilled at developing unique software that fits each agency's needs, which can be used in-house or sold to others. Plus, they help with automating routine tasks and integrating with major online marketplaces, making it easier for agencies to manage data and stay ahead in the competitive online world.
  • Creating custom software for large businesses focuses on solving their unique problems in online marketplaces, such as handling big product catalogs and improving data analysis and automation. These personalized solutions are built to work well with existing big systems, like SAP or Oracle, making them more efficient and easier to use with online platforms like Amazon and eBay. The idea is to make software that the business owns completely, avoiding ongoing subscription costs and keeping their data private and secure. The aim is to ensure that the business stands out in the online marketplace, with software that fits their specific needs and improves their online presence.

I have a software idea, but I am not sure about all its features. Can you help me to validate it?

Yes, we hold workshops with clients as part of our services. They usually last from 16 hours to 80 hours, during which we deep dive into the software's functionality and help you design the concept.

I am worried about the support of my tool. Are you also maintaining the software after its implementation?

Yes, we provide ongoing support and offer flexible maintenance packages. Surely we will be able to find a support plan that works for you. Yet, if you choose that you don't need any support, that's also okay! Since the solution is entirely yours, in the end, it's for you to decide.

What is the cost of the software tool/automation that I want to build?

The cost of your software will depend on its complexity, the systems to integrate with, and the support needed. We created solutions within budgets starting from 7000$ and ending at hundreds of thousands. We will be happy to discuss your requirements and give you a detailed quote during a free discovery call.

Who owns the software after you build it?

Once the project is completed and implemented, you legally own everything necessary to build, maintain, or extend the software in the future, such as "executable" files, scripts, project files, source code, etc.
