Commerce Budgets
Commerce media procurement
Set the inventory, charges, data deliverable, change rights and delivery evidence for a UK commerce media booking.
Procure a commerce media booking against a written purchase record. It should identify the inventory and services bought, the total commitment, who may change it, the report the advertiser will receive, and how exceptions are resolved. A campaign brief states the aim; the purchase record sets out what the supplier has agreed to deliver.
Procurement Process for Commerce Media Bookings in the UK
- Create a written purchase recordIdentify inventory, services, total commitment, change rights, report deliverables and exception resolution process
- Align offer with purchase recordEnsure accepted proposal and order are kept together; distinguish forecast from reserved or contracted quantity
- Secure usable evidenceAgree on report format, access route and timing; separate delivery measures from outcomes
- Record measurement basisSpecify method used (e.g., five-zone framework, Opportunity To See); disclose assumptions for modelled impressions
- Set operating and commercial handoffDefine decision-makers, approval limits, reconciliation levels and exception routes
- Make agency obligations visibleAlign supplier order with agency agreement; use ISBA’s Media Services Framework 2025 for clarity
Turn the offer into a purchase record
Keep the accepted proposal and order together. Name the advertiser, supplier, eligible products, placements or store locations, dates, buying unit, planned volume where applicable, and any conditions attached to availability. Separate a forecast from a reserved position or contracted quantity. A public format menu cannot confirm inventory for this booking.
| Purchase question | Record from the actual offer |
|---|---|
| What is supplied? | Named inventory, eligible products, coverage, dates and delivery basis. |
| What is payable? | Currency, media basis, cap or fixed commitment, additional charges, tax treatment and invoice route. |
| Who can act? | Booking, creative, change and escalation owners, with approval limits. |
| What can be checked? | Delivery unit, reporting fields, definitions, access route and extract date. |
| What happens if plans change? | The agreed process for substitution, cancellation, disputed delivery and any remedy. |
Compare every revised line with the accepted version before it takes effect. A replacement placement, added fee or narrower store list needs a recorded decision, not a later report.
Key Elements of a Commerce Media Purchase Record
- What is supplied?Named inventory, eligible products, coverage, dates and delivery basis
- What is payable?Currency, media basis, cap or fixed commitment, additional charges, tax treatment and invoice route
- Who can act?Booking, creative, change and escalation owners, with approval limits
- What can be checked?Delivery unit, reporting fields, definitions, access route and extract date
- What happens if plans change?The agreed process for substitution, cancellation, disputed delivery and any remedy
Secure usable evidence
Specify the report or extract needed to check the purchase, including breakdown and timing. Agree the delivery format and access route with the supplier and obtain written commitment.
Keep delivery measures separate from outcomes. An online impression can begin rendering without being seen. For in-store activity, a scheduled slot, a recorded play and an estimated opportunity to see answer different questions. Attributed sales describe purchases credited under stated rules; they do not establish sales caused by the campaign.
Record the measurement basis, not just the result
For an in-store booking, state the measurement method the supplier will use and whether it is an established supplier method or an emerging proposal. IAB Europe's in-store proposals are not a final standard; do not treat them as a contractual requirement unless the supplier expressly agrees.
If the booking uses the proposed five-zone framework, identify the relevant zone, from outside the store through to in-aisle environments. For a proposed Opportunity To See calculation, record the inputs: footfall, store count, campaign duration, number of placements, aisle penetration and share of voice.
Where impressions are modelled without sensor technology, ask the supplier to disclose its assumptions. The proposals describe an approach based on footfall and the opportunity for visual contact, not ad play alone, with a tiered way to assess aisle penetration ranging from full beacon deployment to category-level market research.
Do not leave proposed sales measures or reporting windows implicit. IAB Europe's proposals remove sales lift and brand sales lift metrics and align the sales reporting window to 28 days. Record whether the supplier's offer adopts either approach rather than assuming it does.

Set the operating and commercial handoff
Name who can instruct the supplier, approve creative and authorise a change in spend. If an agency is involved, check its paid scope and the supplier's managed-service scope. Neither label establishes which party will challenge a report or resolve a disputed charge.
Before commitment, record the level at which delivery can be reconciled. If a booking names stores but the supplier reports only a network total, location-level fulfilment stays unverified unless more evidence is agreed. Set an exception route and check any adjustment against the actual order; a numerical gap alone does not create a refund or make-good.
The final procurement record should contain the accepted terms, authorised spend, reporting commitment, named owners and any approved changes. It gives the campaign team and finance the same basis for checking what was supplied and charged.
Make agency obligations visible in the handoff
Where an agency buys or manages the booking, align the supplier order with the agency agreement so each party's obligations are clear. ISBA's Media Services Framework 2025 is designed to govern advertisers' relationships with media agencies and sets out terms for media strategy, planning and buying services.
Check that the agency arrangement addresses transparency and agency non-compliance in proprietary media, which the 2025 framework specifically addresses. Keep the agreed agency responsibilities alongside the supplier's booking record so an advertiser can identify who is accountable for each part of the handoff.
