# Inventory and ad-spend decision memo

Blank planning template. Attach the current-scenario CSV or JSON from https://www.iamgeorgekelly.com/field-guide/inventory-aware-ad-spend. Entered assumptions are not verified observations.

- Prepared by / reviewed by:
- Decision time and timezone:
- SKU / variant / fulfillment locations / currency:
- Planning start date (day 1) and window:
- Current spend and proposed increase (record both):
- Decision: test increase / hold increase / review current activity:

## Input evidence

| Input | Value | Source and observation time | Owner / uncertainty |
| --- | --- | --- | --- |
| Available units, excluding committed/unavailable stock | | | |
| Further buffer not already excluded | | | |
| Expected new baseline units/day at unchanged spend | | | |
| Receipt quantity and day it becomes sellable | | | |
| Proposed actual extra spend/day | | | |
| Cost per genuinely additional unit and plausible range | | | |
| Contribution per unit before ads, after returns/variable costs | | | |

Do not subtract commitments twice or count orders already committed as new baseline demand. Separate attributed orders from incremental units. If incrementality is unknown, label the cost assumption accordingly. A planned receipt is not available stock now.

## Scenario review

| Scenario | First buffer breach | Contribution from feasible increase | Decision and reason |
| --- | --- | --- | --- |
| Expected receipt and demand | | | |
| Receipt delayed or missing | | | |
| Higher baseline demand | | | |
| Lower cost per extra unit (more stock consumption) | | | |
| Higher cost per extra unit / lower unit contribution | | | |

Record intraday spikes, shared components, bundles, fulfillment limits, or cash limits outside this uniform single-variant model. If stock is insufficient, do not report the full unfulfilled demand as earned contribution.

## Release and review

- Exact approved campaign or offer change:
- How actual spend and stock will be checked:
- Stock stop condition and latest review time:
- Responsible reviewer and rollback action:
- Receipt confirmation required before release:
- Destination availability and selected-variant evidence after the change:
- Actual outcome and difference from the assumption (complete later):

An average daily advertising budget may not cap actual daily spend at that amount. Use the platform's applicable controls. Restrict promotion without misrepresenting availability. This memo does not authorize or execute a campaign change.
