CPA fell by half with daily pacing tracking at a B2B SaaS for SMBs

    At a B2B SaaS for small and medium-sized businesses, paid media CPA fell by 50% after tracking became daily and automated. Shortening the time between a deviation and the reaction stopped spend from moving in jolts.

    Problem

    The numbers were seen too late. Days went by between a deviation happening and anyone reacting, and the correction came as a jolt: a sharp cut, then an acceleration to make up for it.

    Solution

    Cut the time between event and reaction to a minimum: see every day how much was spent, how much should have been spent and at what cost.

    What we did

    • We automated the account's performance report.
    • We built a pacing view: spend consumed versus forecast.
    • We calculated KPIs from daily spend, with a projection to the end of the period.

    Result

    -50% account CPA after daily tracking was put in place.

    Key learnings

    • In paid media, the problem is rarely a lack of data. It's data that arrives late.
    • Jolts destroy value. Sharp budget cuts and accelerations reset the platforms' algorithm learning and make every conversion more expensive.
    • The shorter the time between deviation and reaction, the smaller the adjustment needed.

    Do it yourself

    1. Build a spreadsheet with one row per campaign per day, with these columns:

      • monthly budget and spend to date;
      • expected spend to date (budget × current day ÷ days in the month);
      • pacing (spend to date ÷ expected spend);
      • conversions and CPA (spend ÷ conversions).

      The ad platforms' native connectors feed this sheet with no development.

    2. Flag anything outside the agreed range, for example pacing outside 90% to 110% or CPA above target. React the same day with small adjustments, never with sharp cuts.

    3. If you prefer, ask an LLM:

      Build a paid media pacing spreadsheet with one row per campaign per day, with monthly budget, spend to date, expected spend to date, % pacing, conversions, CPA and projected spend to the end of the month. Include the formulas and conditional formatting for pacing outside 90% to 110%.
