Designing a finance function for scale

The team and tools that work at ZAR 30m revenue rarely survive ZAR 100m. Here's how to plan the structure, hires and stack ahead of the curve.

What you'll learn
  • Why finance functions break at predictable revenue thresholds
  • The three roles to separate as you scale
  • A target stack for ZAR 30m, 100m and 300m businesses
  • Hiring order and what to outsource

Most founder-led businesses build their finance function reactively. Hire a bookkeeper, then a controller, then someone called 'finance manager' whose job description is everyone else's leftovers. It works — until it doesn't.

The crossover points

We see consistent breakage at three revenue thresholds:

  • Around ZAR 30m: reporting needs outgrow a single bookkeeper.
  • Around ZAR 100m: board scrutiny tightens; ad-hoc analysis becomes a full-time job.
  • Around ZAR 300m: treasury, tax and FP&A each need a dedicated owner.

The three roles to separate

Bookkeeping

Transaction capture, supplier payments, basic compliance. Outsourceable indefinitely. Keep it cheap and accurate.

Controllership

Month-end close, statutory reporting, audit. Needs in-house ownership by ZAR 50m revenue — outsourcing breaks down when the auditor wants someone in the room.

FP&A

Forecasting, decision support, scenario analysis. Often the most under-resourced function in growing businesses, and the one that compounds the most.

A target stack by stage

  • ZAR 30m: Xero / Sage Online, simple payroll, manual board pack in Excel.
  • ZAR 100m: Mid-tier ERP (Sage Intacct, NetSuite SMB), automated AP, FP&A tool.
  • ZAR 300m: Full ERP, dedicated BI tool, treasury management, tax co-source.

Hiring order

  1. Bookkeeper (or outsourced).
  2. Financial controller.
  3. Senior FP&A analyst.
  4. Head of finance / FD.
  5. Tax & treasury specialists.
Finance is a leading indicator of operational maturity. Investors notice — and so do the best hires you're trying to attract.
