You closed the deal. The press release went out. Integration planning is underway. And somewhere in the finance team, a controller is opening a spreadsheet and starting to map 1,400 account codes from the acquired company's ERP into your group chart of accounts. This is the moment the chart of accounts breaks. Not dramatically. Not all at once.

Every FP&A team knows the feeling. The reforecast was published on Monday. By Wednesday, someone in sales has closed a deal that changes the revenue picture. By Friday, procurement has flagged a cost overrun that nobody modelled. The forecast is four days old and already partially wrong. This is not a forecasting problem. It is a data pipeline problem. Finance teams hired analysts for their analytical skills.

I asked Claude what the cash position would be at year-end. The answer was about 30% off. A CFO said this at a finance leaders breakfast in Prague. Almost every CFO in the room had a version of the same story. The problem is not the model. Claude is not bad at maths. The problem is what the model was reasoning over - raw financial data with no governed definitions, no intercompany rules, no agreed methodology for what 'cash position' means at that specific company.

The board asks a question. You know the answer, roughly. But "roughly" is not what you say in a board meeting. So you confirm later. Three days later, the board has moved on. This is not a knowledge problem. It is a data infrastructure problem. This whitepaper is about that problem, and the CFOs who fixed it without replacing a single ERP.

The acquisition closed on Friday. The new CFO walks in on Monday morning. Within 48 hours, the Operating Partner sends a message: when do we get the first financials? The CFO opens their laptop and starts counting. Six ERPs. Three different chart of accounts structures. Two businesses that still report in spreadsheets emailed to a shared inbox. One entity whose close cycle runs two weeks behind the others. This is not a failure of diligence or talent.

You close. The lenders want a covenant report in 45 days. Your finance team is running on spreadsheets, three ERPs, and a shared folder nobody has cleaned since 2019. This playbook is the week-by-week plan for exactly that moment — written for incoming CFOs, interim CFOs, and the Operating Partners who place them.

Post-acquisition financial integration is the process of unifying financial data from a newly-acquired portfolio company's ERP into the PE group's reporting layer — without forcing subsidiaries to replatform. The 8-12 Week PE Financial Data Foundation Framework is a sequenced implementation plan, structured across four phases, that takes a portfolio company from acquisition close to live, automated portfolio visibility.

Most data warehouse projects fail. Not because the technology is wrong. Because the design is. Three weeks for a number that should take three minutes. AI agents generating plausible reports nobody can trace. Two ERPs naming the same metric differently. The spreadsheet swamp. The fire drill before every audit. These problems live in the warehouse layer, in how data is modeled, governed, and made available to the people and AI agents that read from it.

These terms show up in every other LinkedIn post about AI. Everyone uses them slightly differently. So here's how we think about them at Keboola, and what they look like in practice.

Every enterprise AI story right now follows the same plot. You pick a system — Salesforce, Workday, SAP, NetSuite — and you bolt an AI agent on top of it. The agent can summarize deals. It can write follow-up emails. It can pull a report without you clicking through five dashboards. It is genuinely useful. And it is not transformation. What you have built is a smarter interface on top of a system designed for humans.
