Custom software development in Medellín
Krats.tech is one of the software development companies in Medellín: we design and build custom software for SMEs that no longer fit in a spreadsheet or a WhatsApp thread. We work in ASP.NET Core, Windows Forms and .NET MAUI. You can start with a €500 MVP, one usable main flow, and continue in milestones. The source code is yours when payments are complete. If WhatsApp is easier, say so on the form and we continue there.
A hardware store in Belén, a practice in El Poblado or a supermarket with two checkouts often share the same bottleneck. Orders, stock and payment live in messages, in Excel and in the memory of whoever opens the shop. When those pieces do not talk, the price is argued, something out of stock is sold and the afternoon goes to reconciliation. Software development in Medellín, as we do it, starts from that flow, not from a template brought from somewhere else. First we learn how the customer arrives, who dispatches and which number must match at closing. Then we propose the smallest piece that already helps: a page that receives the contact, an order panel or inventory that stops living in three files.
A software company in Medellín that speaks plainly
We choose .NET because a local company should not change language every time it grows. C# covers the public site, the office panel and the checkout program. SQL Server or PostgreSQL store products, prices, users and history. If the counter later needs a Windows Forms screen, or the driver an Android app in .NET MAUI, the data model stays the same. That matters when the business serves in the shop, sends deliveries and opens a second point in another neighborhood. One stack lowers the cost of keeping the system and avoids three vendors who do not know each other. The source code we build is assigned to the client when payments are complete, and there are thirty days to fix defects in the agreed deliverable.
You do not need to know how to program. You say what the company does, where the day gets stuck and what result you want. We turn that into screens and clear rules. We work in Medellín and remotely for Latin America and Europe. The first step can be a €500 MVP, credited if the project continues. A reference landing is €1,500, a corporate site €2,500 and a web application from €4,500. Optional monthly support is €150, with no lock-in. Payments can follow milestones, about 40, 30 and 30 percent, via PayPal, Wise, Mercado Pago, bank transfer or USDT.

Reference prices in euros
Amounts are in EUR and help you place the work, not close a contract without seeing the scope. An MVP, with one usable main flow, starts at €500 and is credited if you continue. A landing is €1,500. A corporate site, with more pages and languages if needed, is €2,500. A custom web application starts at €4,500. Optional monthly support is €150, with no lock-in.
In Colombia the charge can be discussed in pesos at the rate of the moment; the published reference stays in euros so it can be compared. The detail of each band is on the pricing page. If the scope is a counter inventory or an Android app, we quote it on the same basis: written scope, milestones and code in your name.
How a project starts in Medellín
First a short conversation: what the company sells, who uses the system and what hurts today. From that comes a small scope, not an endless document. We build in milestones you can see: a screen, a flow, a closing. You test with real data before delivery. If something in the delivered scope fails, there are thirty days of fixes.
You can write through the contact form. If you prefer WhatsApp, say so in the message and we continue on that channel. krats.tech@gmail.com also works. The meeting can be in Medellín or remote. The full sequence, from analysis to go-live, is on the process page.
Frequently asked questions
Do you only work with companies in Medellín?
The studio is in Medellín and that is the focus of this page: local SMEs that need custom software. We also take remote projects in Latin America and Europe. The meeting can be in person or by video, and the deliverable is the same: code, screens and a written scope.
How much does an MVP cost?
The reference MVP is €500. It covers one usable main flow, not the whole system. That amount is credited if you continue. A reference landing is €1,500, a corporate site €2,500 and a web application from €4,500. Support afterwards, if you ask for it, is €150 a month with no lock-in.
Why .NET instead of another stack?
Because C# and ASP.NET Core cover the public page, the internal panel, a Windows Forms program and an Android app with .NET MAUI without splitting the operation into three contracts. SQL Server or PostgreSQL keep one truth for products and prices. If a case needs another piece, we use it, but the center of the work in Medellín is .NET.
Does the source code stay in my name?
Yes. The code we develop is assigned to the client when payments are complete. There are thirty days to fix defects in what was delivered. Domain, hosting and the main accounts should be in your name from the start, so the business does not depend on the studio to exist online.
Can I write on WhatsApp?
Yes. The public path on this site is the contact form and krats.tech@gmail.com. If you prefer WhatsApp, say so in the message and we coordinate on that channel. We do not show a number on the site until the phone is configured: we do not invent a link.
Tell us the operation
Write what the company does, what gets stuck today and whether you want to start with an MVP. We reply through the form. If WhatsApp is better, say so in the same message and we continue there. A technical brief is not required: the day’s flow is enough to propose the next step.
