Which content agencies supplier comparison method fits your buying team?

What to take away

Why does a content agencies supplier comparison go wrong?

Most comparisons collapse because the buyer scores presentation quality instead of delivery risk. Agency pitch decks are built to win rooms, not to forecast output.

A second failure is comparing unlike scopes. One supplier quotes strategy only. Another bundles production, distribution and reporting. The numbers look comparable and are not.

Third, buyers skip the exit question. If the contract locks you in for twelve months with sixty days notice, the cheap option may cost more than the expensive one.

Another common fault is scoring on averages. One impressive case study can lift a weak supplier above a steadier one. Score each criterion separately and keep the raw notes, so a later review can show why the ranking changed.

The content agencies tools and supplier guide sets out the full buying sequence if you need the wider context before scoring.

Should you score suppliers or run a paid pitch?

A weighted scorecard suits repeatable, lower-value appointments. You define criteria, weight them, and score every supplier against the same evidence. It is fast and defensible.

A paid pitch suits complex briefs where you cannot judge capability from documents alone. Paying a pitch fee, for example £1,500 per agency, keeps the process fair and filters out suppliers who are not serious.

Pitch fees should be paid to every shortlisted supplier on the same terms, and the brief should be fixed before invitations go out. If you change the brief mid-process, expect revised quotes and a weaker comparison.

Reference-led shortlists work when the market is small and reputation travels. Framework call-off works for a public body only if it is eligible to use a current agreement whose scope covers the work. Crown Commercial Service's Marketing and Creative Services framework (RM6124) is a named example; check its current status, scope and user eligibility before relying on it.

For public procurement, confirm the applicable regime before choosing a route. In England, Wales and Northern Ireland, procurements commenced on or after 24 February 2025 are governed by the Procurement Act 2023 and Procurement Regulations 2024; earlier procurements may remain under the Public Contracts Regulations 2015. Scottish devolved authorities follow separate rules, including the Procurement Reform (Scotland) Act 2014. Check relevant opportunities and notices through Find a Tender Service or, for Scottish notices, Public Contracts Scotland.

Advertiser guidance from the ISBA knowledge hub covers agency relationship models and remuneration, which helps when you compare fee structures across shortlisted suppliers.

What belongs in the scoring criteria?

Score five groups: strategy capability, production capacity, measurement, commercial terms and risk controls. Give each a weight before you see any pitch.

Normalise scope before scoring. Convert each proposal into the same units, such as articles per month or campaign cycles per quarter, and price the same set of deliverables.

Risk controls should include information security. Ask whether the supplier has an independently certified information security management system to ISO/IEC 27001; where service quality is relevant, ISO 9001 may also be useful. Cyber Essentials is a UK government-backed cyber-security certification scheme. For ISO certificates, record the issuer and scope; where the issuer claims UK accreditation, verify that with the United Kingdom Accreditation Service (UKAS).

Do not treat Online Safety Act compliance as a blanket scoring line for every brief. The GOV.UK page on amendments to the Online Safety Bill records an earlier legislative stage; where a brief supports a regulated service, ask how the agency's work fits the service provider's duties.

Score evidence, not promises. A named account lead with relevant sector work beats a generic case study.

Which comparison method fits your situation?

The figures above are illustrative examples, not market benchmarks or universal thresholds. Use them as prompts: a weighted scorecard suits repeatable scopes that can be assessed from evidence; a paid pitch suits complex work that documents cannot demonstrate; reference-led selection suits a small market; and framework call-off suits an eligible public buyer when a current agreement covers the scope.

Where two suppliers score within a few points of each other, ask both to quote a fixed scope for the first quarter. Price is a better tie-breaker than pitch chemistry.

Once you have shortlisted, collect comparable data on fees, output volumes and reporting cadence. Our guide to tools and data sources for comparing content agencies explains which data sources are worth pulling into that comparison.

Common questions

How many suppliers should we compare?

For most buying teams, a figure of three to five works well. Fewer than three gives you no real choice. More than five adds cost without improving the decision.

Should the comparison include a pilot?

Yes, where the brief allows it. A paid pilot, for example four weeks at £3,000, reveals working style and output quality far better than a pitch.

What kills a supplier comparison fastest?

Comparing scopes that are not alike. Normalise deliverables, volumes and reporting before you score anything, or the cheapest quote will always look best.

How long should the process take?

Allow four to eight weeks for a scorecard process and eight to twelve for a paid pitch. Rushing shortens the reference checks that catch most problems.
