For sellers & vendors

Juggling between dozens of different tools, a lot of time wasted on manual click-intensive tasks, and limited access to analytics, among others, are all common struggles of Marketplace Sellers and Vendors. But don't worry, we're here to help!

Solving Seller Challenges with Software & Automations

Navigating the complexities of online marketplaces like Amazon, eBay, Otto or Walmart can be challenging, but with custom software solutions, it doesn't have to be. We believe in making technology simple and accessible. Whether it's a nagging problem that's been bothering you or a brilliant idea that's been brewing in your mind, we're all about finding solutions that click.

How it works?

Our approach is straightforward: you bring us your challenges or ideas, and we apply our technical expertise to create a solution. We've turned warehouses into models of efficiency with automation, transformed data into nuggets of wisdom, crafted repricers that would make any tech enthusiast's heart sing, and streamlined workflows so smoothly that they practically run themselves.

And the best part? Once we build it, you own it. Forget about those never-ending subscriptions and the "one size disappoints all" third-party tools. Each solution is yours forever, tailor-made to fit your business like a glove and flexible enough to evolve with your needs.

With Deltologic, you're not just getting a software; you're gaining a tech partner who's committed to your success in the marketplace. Watch this 2 minutes video recorded by Raffy, our Project Manager, to learn more on how custom software tools can benefit your business: LINK

Our approach

Utilize your own know-how

You can automate your processes in a completely unique way, instead of using the tools that everybody else already does.

Make it fully custom

Integrate with marketplaces and gather, transform, and visualize the data, automating your operations in any way you want - the sky is the limit.

Get rid of subscriptions

Monthly fees can be expensive, especially at scale. Building your own tools with our help will keep your recurring costs lower.

How does the development process look like?


Discovery call

We'll start with a call to understand your business needs and the goals of your custom solution.

Using agile methodologies, we develop, test, and refine your new solution, keeping you updated at every step.



And we don't stop there – our ongoing support includes maintenance, fixes, and adding new functionalities.

Frequently asked questions

We've put this list together to give you quick and easy answers to questions you might have when reading about our solutions for Sellers and Vendors. If you don't find the answer to your question, don't hesitate to contact our team. We will be more than happy to help you out!

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 want to develop a custom solution but it's not related to Amazon or any other marketplace. Can I still build it with you?

Yes, we are a software agency and work with clients from many different industries, such as logistics, agriculture, automotive, etc. We possess unique know-how in the marketplace field, but we are not limiting ourselves to just this niche.

How are you estimating the prices of your custom solutions?

We always provide you with a transparent cost estimate. We calculate this estimation based on our hourly development rate. You may pay this amount in monthly instalments, but in the case of larger projects, we will usually require some down payment to get started. This way of estimation provides you with many benefits: you will know exactly how much the solution costs, you don’t have to worry about any revisions, and paying in instalments will smooth out your cash flow.

Who owns the tool after you build it?

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