Building your own financial data system sounds lean, flexible, and smart — right up until year two. This guide gives you the honest picture most vendors won't: what a production-grade finance system actually costs, what teams almost always miss, and a decision framework built for CFOs who need to get this right the first time. Your data team is confident. The architecture looks solid.

This is a Data App that collects structured product submissions from a team, validates them, queues them for approval, and writes approved entries directly to a Keboola table. I built it with Kai in one conversation. No Google Sheets. No broken column headers. No emailing CSVs. If you've ever needed your team to submit structured data - new products, budget inputs, campaign briefs, vendor details - and the spreadsheet approach keeps falling apart, keep reading.

Data Apps are interactive web applications that run directly in your Keboola project. They let you visualize, explore, and interact with your data without needing external BI tools. Think of Data Apps as your custom dashboards, built exactly how you need them. Now, let's see how Kai makes building Data Apps effortless.

Three departments walk into a board meeting. Sales says revenue grew 12%. Finance says 9%. Operations says 8%. Nobody is technically wrong, but it still slows every decision down. This template should give you a head start to fix that.

If you've just enabled Kai in your Keboola project, you might be wondering: "Okay, now what?" This guide walks you through your first conversation with Kai, following the same steps I demonstrate in my introduction video.

Last week we publicly released Kai, our in-platform AI assistant, a data engineering agent that can build integrations, write transformations, debug failures, and document your entire project. I'm extremely proud of the team and what we've delivered. Yes, everyone has an AI assistant now. But most are chat wrappers that look great in scripted demos and fall apart with real work.

Navigate to Workspaces → SQL Editor in your Keboola project. Write or paste your SQL query in the editor. ‍

You've outgrown Excel for consolidation. But what comes next? Anaplan starts at $200K+ - and still assumes your data is already clean. Your data team wants to build something custom - but "three months" always becomes twelve. And every vendor says they're the answer. This guide compares every realistic consolidation path side by side. Real costs, real timelines, real trade-offs. Including when staying with Excel is still the right call.

Your data team is confident. Your budget is approved. And building your own system still sounds like the smart, lean choice. This guide is for the CFOs who've been there - or who are about to be. Three chapters. Real costs. The two things every team skips in version one. And a decision framework you can actually use.

Your finance team wastes 14 days every month on manual consolidation. Your close stretches to 15-25 days. And you're one key person departing from chaos. The brutal math: Your "free" Excel process actually costs $850K+ annually in wasted time, errors, and missed opportunities. Meanwhile, leading multi-entity CFOs just cut their close time by 80% and freed their teams for strategic work instead of reconciliation hell.
