Retool: Our go-to tool for fast business apps

What is Retool? — The kit for internal tools

In short: Retool is a kit for business apps. Instead of setting up every app from scratch, Retool allows you to click together interfaces using drag-and-drop and connect them directly to data sources (such as SQL databases, Google Sheets, or APIs). Just the thing when you need fast, flexible dashboards or admin tools. Business processes can also be automated without much effort. So the trick: You save yourself countless hours of development work and still have the flexibility to incorporate your own logic or code if you want something more special. Thanks to the low-code approach, no deeper programming knowledge is required to get started.

How it works: From data source to interface

As Data & AI Consultants, we are fans of tools that pragmatically add value. Retool has established itself in our everyday lives because it enables us to quickly transform ideas into working prototypes or even productive solutions. For us, the most important features are:

• User-friendly interface: Components such as tables, forms, and charts can be used via drag-and-drop.
• Diverse database and API integrations: Support for SQL, NoSQL, REST, GraphQL, and more to directly integrate data from a wide range of sources.
• Advanced user and rights management: Precise control over who can see and edit which data.
• Templates and component library: Many directly usable modules for typical use cases, such as dashboards or data management tools.

Practical examples: Our use cases with Retool

Automated travel expense reporting

Many companies still juggle Excel spreadsheets when it comes to travel expenses. We have with Retool developed an app that records travel expenses, automatically calculates them and provides them with a clear overview for billing. This saves time, prevents errors and provides transparency. Retool can make such a tool flexible and highly integrated — from document management to automated approval and analysis of costs.

Core functions of a travel expense tool

• Digital recording of travel documents (hotel, flight, food) through mobile uploading.
• Automated approval and billing processes for quick reimbursement.
• Integration with accounting systems and databases such as Google Sheets, SAP, or SQL.
• Regular reminders, validation of entries, and compliance with travel policies through workflow automation.

Dynamic workload planning for teams

In consulting projects, the question is “Who has capacity and when? “decisive. With Retool, we have a Utilization planning app built, which combines project and personnel data. In this way, we can see at a glance how busy teams are and where there is still potential.

Core features of a workload planning tool

• Recording and display of capacities: The availability and assignments of individual team members are presented, for example, in weekly, monthly or daily views.
• Visualization of overload and underload: Color-coded load indicators, automatic warnings in the event of bottlenecks or free capacities.
• Integration with external systems: Data from personnel administration, time recording or project databases can be easily linked together and updated in real time.
• Flexible filter and roller concept: Select by department, project, role, or skills—ideal for project leaders and team managers.
