CC-AA02 — AR & AP: Working Capital Operations

  • Course

See AR and AP as one cash conversion system instead of two separate functions. Map both subledger cycles end-to-end, find where cash gets stuck, classify waste in each workflow, and build a working capital tool that connects receivables, payables, and cash conversion into a single operational view.

CC-AA03 — Audit Readiness

  • Course

Turn audit prep from an annual fire drill into a project you can run from a tracker. Anticipate requests before they arrive, close out prior-year findings so they don't recur, and build a readiness tool that makes each audit shorter than the last.

CC-CO01 — Commercial Controlling

  • Course

Build a shared artifact that Sales will actually use. Connect revenue drivers (price, volume, mix) to financial outcomes so variance explanations match how the commercial team thinks, and create the reporting rhythm where you're in the room when decisions get made.

CC-CO02 — Manufacturing Controlling

  • Course

Build a shared artifact between finance and operations that connects plant throughput, standard costing, and variance analysis into one view the plant manager can read. Identify where cost leaks hide in the production-to-reporting chain, and create the reporting rhythm where your numbers drive decisions instead of confirming what everyone already suspects.

CC-CO03 — Project Controlling

  • Course

Build one portfolio view where milestones, costs, revenue recognition, and risk sit in the same place. Standardize how PMs report progress so you stop translating between fifteen different formats, and create the early warning system that catches overruns while there's still time to act.

Finance & Economics

Fuel growth with capital.

Corporate finance, financial analysis, and the economic principles behind business decisions.

  • Waitlist

CC-FE01 — Cash, Treasury & FX Management

  • Course

Stop reacting to the bank balance and start predicting it. Build a rolling 13-week forecast that connects operating cash flows, treasury positions, and FX exposure into one view, with scenario analysis that answers "what happens if the receivable slips two weeks" before it actually slips.

CC-FE02 — Capex & Business Case Management

  • Course

Build the business case framework your organization keeps saying it needs. One evaluation template that makes investment requests comparable, one approval tracker that shows where requests sit, and one post-investment review dashboard that answers the question nobody currently asks: did the money do what we said it would?

CC-FE03 — Digital Finance Analytics

  • Course

Understand what analytics technologies actually do (including AI and LLMs) so you can evaluate vendor claims and internal proposals with judgment instead of hype. Then build the portfolio oversight tool that scores every initiative against business value, tracks projected vs. actual ROI, and gives your CFO one view of what's working and what isn't.
