Operating Budget Reforecast Agent

Produce a defensible full-year operating cost reforecast with explained variances

Operating Budget Reforecast Agent: what goes in, what the agent does and what you get

What it does

Each quarter, operations leaders must tell finance where their spend will land for the year. This agent prepares that reforecast. It reads year-to-date actuals by cost center, the current budget, volume plans and known rate changes such as wage increases, freight rates and energy contracts. For each line it projects the rest of the year using the method that fits: run rate for stable costs, volume-driven for variable costs, and known commitments for contracts. It then checks large variances. Any line more than 5% off budget needs a stated driver from the site owner, so it asks for one and waits. It also checks the total ties to the general ledger. If either check fails, it loops back to the data. The executive signs off the numbers sent to finance. Edge case: a one-time repair hit in March, so it removes it from the run rate.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

It picks run rate, volume-driven or committed-cost projection per line based on how the cost behaved year to date, and strips one-time items from run rates.

  • Use run rate when monthly spend varied less than 10% year to date
  • Use volume-driven projection when cost tracked units shipped or produced
  • Treat items over $25,000 that will not recur as one-time
  • Require a written driver for any line more than 5% off budget

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Variance threshold that needs a driver (default 5%)
  • One-time item threshold (default $25,000)
  • Days site owners get to reply (default 2)
  • Cost centers in scope
  • Reforecast format required by finance

What keeps you in control

It always asks you first

  • Final reforecast submitted to finance
  • Any reallocation between cost centers

Hard limits

  • Never submits figures to finance without sign-off
  • Never edits ledger data
  • Keeps projection method visible for every line

It stops when

  • Done: totals tie, every large variance explained, executive signed off
  • Stop: ledger data unavailable, so it reports which months are missing

An example run

What happensIn the Q2 reforecast, the agent projected maintenance spend at $2.31M against a $2.05M budget. Actuals first failed to tie by $84,000; it found a cost center for the new Dallas site was not mapped and re-pulled. Three variance drivers were missing; after a reminder, two site leads replied. The COO signed off with one line marked as an open risk.
