Finance Data Analytics: from raw transactions to automated dashboards
Stop rebuilding the same reports every month. In two days, your finance team learns to clean messy exports, combine data from multiple systems, reconcile transactions and build an invoice ageing dashboard that refreshes itself.
Close 2026 with a receivables dashboard ready for 2027.
Your capstone: an invoice ageing dashboard like this one, built on a realistic Lagos dataset. Sample shown with fictional data.
Organisations whose teams we have trained and supported
From leading industrial conglomerates and insurers to state healthcare commissions.
Your finance team knows finance. The spreadsheets are what slow them down.
Data from the ERP, bank and billing system never lines up, so hours go into copy and paste.
Mismatches are found by eye, late, and sometimes not at all.
The same reports are rebuilt by hand every period, under deadline.
Management asks who owes what and for how long, and the answer takes days.
Built for the people who produce the numbers
Two days. One real case study: invoice ageing.
Every session is hands-on in Excel and Power BI. You work on the same dataset from the first export to the final dashboard.
- Clean messy system exports with Power Query
- Merge invoices, payments and bank data from different systems
- Reconcile transactions and flag mismatches automatically
- Spot unusual patterns that point to control gaps or leakage
- Ageing buckets and days sales outstanding (DSO)
- Build an interactive invoice ageing dashboard in Power BI
- Set up refresh so recurring reports update themselves
- Document sources and KPIs so reports are auditable
Not just notes. A finished invoice ageing dashboard and a reusable template you can point at your own company's data on Monday, plus a Skillahead certificate of completion.
