Chartered Accountant (SA) · FP&A and business control
Andrew Siebert CA(SA) is a South African Chartered Accountant and the founder of Knowledge Tap BV, specialising in FP&A, business control, post-merger financial integration and project profitability across multi-entity, multi-currency service and project businesses.
In short
Andrew's work sits between operational leadership and group finance. In merged and multi-site organisations those two ends of the business routinely describe the same month in incompatible terms — one in consolidated margin and recognition, the other in crews, permits and unsigned milestones. Reconciling that, and building the reporting and models that keep it reconciled, is the core of the practice.
The emphasis is on capability that stays behind: models the client's own team owns, definitions everyone has agreed, and a close routine that runs without the consultant in the room.

Professional background
Building post-merger integration initiatives: strategic KPI frameworks, business performance analysis, and the financial infrastructure that lets newly acquired businesses operate with clarity and control. Acting as the finance bridge between legacy organisations, operational leadership and group finance — harmonising local and head office expectations, running margin reviews and cost-to-complete forecasting, aligning backlog, order intake, book-to-bill, utilisation and billability into a single reporting suite, and driving working capital improvement through harmonised billing milestones and unbilled WIP reduction.
Partner to the CFO and financial sparring partner to the Supply Chain Director. Led budget, forecast and outlook cycles; contributed to post-merger integration including OneStream consolidation, KPI harmonisation, definition standardisation and baseline creation; owned profitability and value-driver analysis across projects, services and install-base portfolios; led analysis of pricing, billing and collections, overhead absorption, internal cost rates, FTE productivity and capacity utilisation; designed executive Business Health Check dashboards; built scenario models for facility optimisation and footprint reduction; and contributed to ERP transformation across Dynamics CRM and Oracle Fusion Cloud.
Held the financial planning and analysis function for business controllers, financial controllers, the finance director and the CFO through a strategy change. Three- and five-year medium-term outlooks, monthly performance reporting and modelling, overhead, FTE and utilisation analysis, cost rate modelling, BI dashboard development, and a single-source-of-truth model. Coached two new team members into the function.
Financial right hand to the Business Unit Director, co-presenting business unit performance financially and operationally. Forecasting and strategic assessment across four branches; analysis of cost management, headcount, sales and margin, pricing, field hourly rates, absorption and productivity; supply chain and fleet cost management; and point of contact for major project approvals against financial KPIs.

Common questions
It builds the finance capability a business needs and does not yet have — integration frameworks, forecast models, project profitability reporting, KPI definitions and consolidation processes — and hands them over with the documentation to run them. The deliverable is a working routine, not a recommendation.
Services and project businesses, typically multi-entity and often mid-integration: recently acquired, recently merged, or running several sites and business units whose numbers no longer consolidate cleanly.
With scope. A short review establishes whether the problem is a reporting problem, a definitions problem or a process problem. Where the answer is smaller than expected, the engagement ends there.
