In honor of FY24, here’s a brain dump of 24 deadly mistakes first-time (and to be honest, also very senior) FP&A professionals make when preparing their annual operating plans.

Use this as a final gut check before you start the new year.

Jon Snow
  1. Not allocating stuff early enough

    1. Makes future periods hard to compare, and makes your G&A look bloated early on. It’s common to overload G&A with rent and subscriptions for longer than you should because it’s the easy thing to do.

  2. Building long term models that are not based on bottoms up assumptions

    1. You can't just straight line opex growth - the company will change its mix of employees by department over time.

  3. Allowing the CEO's direct reports too much autonomy to negotiate vendor purchases

    1. Your head of engineering knows Kotlin. He does not know how to negotiate multi year contracts based on payment terms.

      Chriss Voss: Probably doesn’t know Kotlin, but will negotiate your ass off.
  4. Hiring analysts who have strong accounting backgrounds but can’t do financial modeling

    1. OMG you don’t know what a Vlookup is, do you? Take a lap. And then don’t come back.

  5. Avg salary per person creep

    1. Not testing it on a quarterly basis. Can get out of whack fast when you are at the scale and now need to bring in managers to sit between the C-suite and employees. That middle management layer is expensive as hell.

  6. Making two for one swaps internationally for lower cost employees

    1. It never actually works out to a fair trade after you factor in benefits and the admin cost of adding another node to the org.

  7. Not budgeting for laptop refreshes for existing employees

    1. If you actually remember this, you are a far better planner than I, a man who has forgot this seven years in a row.

      Refresh.
  8. Not forcing travel to follow the individual back to their department

    1. Put the budget there so you don’t have to charge other cost centers (like marketing for conferences). When travel goes over budget (and it will), failing to do this will lead to finger pointing.

  9. Not benchmarking your effective commission rate early on, and letting it creep up with sales hiring

    1. Effective commission rates will grow by at least 5 percentage points during one year of hyper growth. And then one morning you wake up and realize you are paying two managers, an SE and a BDR on every deal.

  10. Buying FP&A software licenses for people in non finance departments

    1. They will never open your slick finance app. I’m 0 for 4 on getting my VP of People to use a cloud based planning platform. Also, if you are an FP&A tool, you should sponsor this newsletter and I’ll take back what I said.

  11. Blindly relying on salary data from the people team

    1. It's always more expensive to hire people than what Pave or Mercer tells you. Do a gut check based on what you are seeing from the economy, and then add 3% to the plan.

  12. Not opening enough BDR roles and promoting them all to AEs

    1. Congrats, you now have no one to hand leads to your new AEs!
