Costs and pricing
Part of PR agencies costs and pricing: building a budget that measures real value
Costing a PR brief in four ledgers, with blank units instead of fictional amounts
A source-led method for costing an England PR brief, with blank units for agency work, buyer time, external services, VAT, change and safe exit.
Starting a PR brief with an average retainer puts a number before a decision. Begin instead with a service boundary that two England suppliers could price in identical units. Every amount below is a blank for the buyer to complete from dated quotations and accepted proposals.
What to take away
- Name one England case and its operating period before discussing money.
- Keep supplier cash, buyer cash, buyer effort and transition exposure as four linked ledgers.
- Fill every blank from a dated quotation, order form or invoice, never an assumed average.
- Fix the reconciliation rule before the first invoice arrives.
- Confirm VAT treatment with a tax reviewer and hold gross cash until recovery is evidenced.
Define one purchasable England case
- Name the case and its operating period, such as press-office support for a defined quarter in Leeds.
- Split the request into tasksresearch, drafting, approval handling, media enquiries, spokesperson preparation, monitoring, evaluation and handover.
- Give each task one purchasing unitaccepted work package, authorised hour, service period or documented third-party item.
- Mark each task fixed in scope or consuming reserved capacity.
Do not buy "coverage" as if an independent editor worked for the agency. AMEC's evaluation taxonomy separates communication outputs from audience outcomes. It supplies shared vocabulary, not an England price list.
Build the four ledgers
| Ledger | What it records |
|---|---|
| Supplier cash | Agency charges, production, monitoring, distribution, approved expenses |
| Buyer cash | Supplier payments, VAT cash effect, credits, refunds |
| Buyer effort | Briefing, evidence retrieval, approvals, procurement, legal and security escalation |
| Transition exposure | Onboarding, migration, corrections, archive, export, access removal, continuity cover |
Four linked cost ledgers
Supplier cash
- What it covers
- Agency charges and expenses
- Example rows
- Production, monitoring, travel
- Row labels
- One-off or recurring
Buyer cash
- What it covers
- Payments and VAT effect
- Example rows
- Refunds, credits, services
- Row labels
- Fixed or variable
Buyer effort
- What it covers
- Internal time and approvals
- Example rows
- Briefing, legal, security
- Row labels
- Committed or contingent
Transition exposure
- What it covers
- Onboarding and exit
- Example rows
- Migration, archive, deletion
- Row labels
- Currency and VAT basis
For every row record currency, VAT basis, quantity, unit, service period and billing period. Add the source dates behind each figure, an owner and a confidence level. Label each row one-off or recurring, fixed or variable, committed or contingent.
Example: a blank ledger for a named England operating period
A Leeds manufacturer briefs press-office support for 1 January to 31 March 2027. The ledger below keeps every quantity and amount blank.
| Row | Unit | Quantity | Net unit charge | Source |
|---|---|---|---|---|
| Issues preparation | Accepted work package | ____ | £____ | Dated quotation |
| Press-office support | Authorised hour | ____ | £____ | Order form |
| Media monitoring | Service period | ____ | £____ | Invoice |
| Spokesperson training | Delivered session | ____ | £____ | Proposal |
Nothing in that table is a quotation until a supplier signs it.
Calculate three amounts from the contract
net supplier amount = fixed charges + sum(approved quantity x net unit charge) + authorised expenses
gross cash need = net supplier amount + confirmed VAT cash effect - documented credits
economic cost = finance-approved external cost + sum(internal hours x loaded labour rate)
Three costing equations
- Net supplier amount = fixed charges + approved quantity x net unit charge + authorised expenses
- Gross cash need = net supplier amount + confirmed VAT cash effect - documented credits
- Economic cost = finance-approved external cost + internal hours x loaded labour rate
These equations are a structure, not a price. Each blank must come from an accepted proposal, order form, invoice or buyer ledger. HMRC publishes current VAT rates, but the rate that applies follows the actual supply.
HMRC's business-expense guidance makes recovery conditional on registration, business use and evidence. A qualified tax reviewer should decide whether any VAT is recoverable. Until then, hold the gross cash exposure.
How England agencies price the work
Three structures dominate. A retainer prices capacity across a service period, so unused time may lapse or roll forward. Project pricing covers a defined deliverable. An hourly rate bills authorised time, including meetings and rework. Many briefs mix all three. Ask which unit each line uses, and whether the retainer guarantees output volume or only team access.
Expose change and reconcile it
Ask suppliers what consumes reserved capacity, how unused time is treated, which revisions are included, and who authorises out-of-scope work. Ask tool providers about licence term, named users, coverage, usage limits, renewal, cancellation, export and deletion.
Run sensitivities with buyer-approved lower and upper inputs for workload, approval time, production and travel. Treat those as planning cases rather than benchmarks. Pause commitment when a mandatory line has no source or a variable has no measurable unit.
Design reconciliation before the first invoice. Match each billed line to its purchase authorisation, contract unit, period and named approver. Put a disputed quantity in its own queue rather than rolling it into the next period.
If the agency processes personal data, such as journalist contacts, the contract needs processor terms plus retention and deletion rules. The ICO's UK GDPR guidance sets out what those clauses must cover.
Before you commit
- One England case named, with a dated operating period.
- Every task has a purchasing unit.
- Every row carries currency, VAT basis, quantity, unit and service period.
- Each row labelled one-off or recurring, fixed or variable, committed or contingent.
- Sensitivities run on buyer-approved lower and upper inputs.
- Every mandatory line has a source document.
Common questions
What replaces an average retainer at the start of a brief?
A service boundary two prospective suppliers could price in the same units, with a named operating period. Amounts stay blank until a supplier quotes against that boundary.
How is VAT handled on PR agency costs?
The rate follows the actual supply, and recovery depends on registration, business use and evidence. A tax reviewer decides whether any VAT is recoverable, so hold gross cash until then.
What happens when a billed line cannot be reconciled?
Move the disputed quantity into its own queue rather than rolling it into the next period. Record the date raised, the evidence requested, the credit route and the point when further variable work stops.
