Review advertising budgets with margin and stock

Prepare a weekly advertising budget review that separates attribution, business constraints and the decision to change spend.

Your question

What evidence do we need before moving advertising budget?

THE SHORT ANSWER

A useful budget review combines comparable platform reporting with store economics and available stock. It records what is known, what is missing and the limits of any proposed change. A high reported ROAS can justify investigation; it does not prove that extra spend will generate profitable incremental sales.

ILLUSTRATIVE EXAMPLE

A budget note the team can act on

Illustrative decision, not account advice: an outerwear campaign reports strong ROAS, but its advertised jacket is missing key sizes. Keep the current daily budget while the team checks the following. Do not use the ROAS alone to justify more spend.

Decision itemRecord for this example
Budget proposalHold the daily budget; do not increase spend on the unavailable offer.
Commercial checkFinance confirms contribution after matched refunds and the agreed variable costs. Missing costs remain unresolved.
Stock checkMerchandising confirms saleable sizes, replenishment and a relevant alternative destination.
ReassessmentThe campaign owner reviews the decision after confirmed replenishment or a verified destination change. Record what was actually implemented.

Separate reporting from economics

Record the platform attribution window and compare order timing with the store. Note discounts, cancellations, returns and variable costs before interpreting revenue as contribution. Keep platform-attributed purchases separate from total store orders. If the cost data is unavailable, describe the decision as provisional rather than presenting an invented profit figure.

Check what the budget can actually sell

Review stock by relevant product and size, not just total units. Confirm the delivery promise and expected replenishment. A campaign pointing at an almost unavailable collection may need a different product focus before additional spend. Ask the merchandising owner to confirm that the proposed direction matches the commercial priority.

Decide the change and its limit

Write down the budget you want to change, the maximum spend and the date for reassessment. Name the decision owner and the result they will review. Record other changes that could affect the comparison. Holding the budget while fixing measurement or availability can be a useful decision.

Use this at work

  1. Align reporting windows and document missing campaign data.
  2. Review contribution, returns and size availability with their owners.
  3. Approve a bounded change or record why the budget stays unchanged.
