Use Update cost when the tracker has the traffic you want to analyze but its recorded spending differs from the amount you want to report. A typical case is an ad platform finalizing yesterday’s bill after Metricanic collected estimated per-visit cost. The correction changes campaign Cost and derived metrics such as Profit, ROI, CPC, and CPA for the selected period. It does not edit the traffic source’s bill or change future traffic-cost settings.

​
Choose an amount you can justify

Suppose yesterday’s campaign recorded 1,000 visits, USD 200 revenue, USD 40 visit cost, and USD 10 event cost. The original aggregate cost is USD 50 and profit is USD 150. If the amount you want reported as the campaign’s total cost is USD 60, a Total spend correction sets aggregate cost to that amount, subject to allocation precision. It replaces the aggregate cost calculation. It does not add USD 60 to the existing USD 50. The resulting profit is USD 140. Raw event amounts and Cost N columns keep their recorded values, so they can still show the original event expenses. When your known bill covers only part of the campaign expense, decide which total belongs in the report before applying the correction. Existing event cost is not added on top of the corrected total automatically.

​
Pick the correction mode

Use CPV or CPA when a rate is the source of truth. Use Total spend when you know the bill for a day or range. Amounts are in USD and may be zero. A CPA correction uses Metricanic Conversions. If you count both lead submission and approval as conversions, both contribute to that corrected cost. With visits but zero counted conversions, a CPA correction produces zero cost.

​
Apply yesterday’s bill

  1. Open Campaigns, select the campaign, and click Update cost.
  2. Choose Update cost in the dialog.
  3. Select yesterday in the timezone used for your bill.
  4. Choose Total spend and enter 60 for the example.
  5. Review the affected campaign and date, then confirm.
  6. Let the submitted update finish processing and refresh the same campaign report.
  7. Confirm Cost is approximately USD 60 and Profit is approximately USD 140 for the example scope.
The current manual correction window is the last 30 closed calendar days in the selected timezone. Today is excluded. The interface disables correction for archived campaigns and selections with zero visits. A positive correction also fails for any selected day that has zero tracked visits, even if the whole range has traffic. Queued means the update was submitted. It is not confirmation that every selected day completed successfully.

​
Be deliberate with a multi-day total

For Total spend across several days, the amount can apply per day or to the whole range: A range total is split evenly across dates. It is not weighted by each day’s traffic. Within each day, the allocation uses tracked visits. If your bill shows USD 10, USD 30, and USD 50 on those three days, update the days separately with their actual amounts. Entering one USD 90 range total would distribute the same overall bill differently and change daily profitability.

​
Understand why a corrected total can move later

Total spend is stored as a per-visit rate based on the visit count available during processing. CPV and CPA corrections are also rates when the report calculates cost. For example, USD 60 divided among 1,000 visits yields a USD 0.06 rate. If late data makes the report count 1,010 visits for that day, that rate yields USD 60.60. Reconcile the day again once the traffic count has settled if the report needs to match the final bill. Small differences can also come from numeric precision. The correction is a reporting calculation, not a permanent freeze of the day’s dataset.

​
Restore or diagnose a correction

To remove a manual correction, select the campaign, open Update cost, choose Restore cost, select the affected closed days and timezone, then confirm. After processing, reports use the original tracked cost calculation again. For configuring new traffic rather than historical reconciliation, see Traffic costs.
