A social commerce budget that follows the money from settled revenue to returns

Build the budget around settled orders and contribution, not views or checkout revenue. An England-based retailer needs to capture product cost, returns, delivery, creator and media work, platform or payment deductions, software, staff time, tax treatment, compliance and failure recovery. 5% plus 20p per successful UK card charge, so name the rate source for each deduction.

The price shown on a supplier page is only one input.

Research closed on 5 September 2026 for this planning edition. It contains no market rate, vendor quote or forecast result. Product charges and tax treatment can change, so finance and tax reviewers should verify the retailer's facts and current records before a 2027 budget is approved.

What to take away

Build the budget around settled orders and contribution, not views or checkout revenue.
Separate setup, committed and variable costs, and include contingent costs in the risk model.
Use a contribution formula that follows settled England orders to returns and contribution.
Treat refunds and returns as dated states, and show immature cohorts separately.
Keep customer pricing separate from programme cost, and compare pricing models on common scenarios.

Choose one accounting boundary

State the period, geography, channels, products and order states included. Decide whether the analysis covers England sales only or a wider UK operation. Keep discovery, checkout and fulfilment routes separate where fees, returns or evidence differ.

Define the accounting boundary

State period, geography, channels, products
List included order states
Choose England-only or wider UK
Separate discovery, checkout, fulfilment routes
Use settled revenue after cancellations and refunds
Exclude VAT only if supported
Record invoice currency and conversion method

Use settled revenue after cancellations and refunds. Exclude VAT from revenue and costs only if the business's accounting and recovery treatment supports that basis.

HMRC's VAT expense guidance explains that VAT-registered businesses may reclaim VAT on qualifying business purchases, subject to conditions and records, and describes limits for private use, exempt supplies and the Flat Rate Scheme.

A tax adviser should set the budget basis, not copy a generic net-of-VAT model.

Record actual invoice currency and the conversion method used in the accounts. Do not compare a sterling quote excluding VAT with a foreign-currency charge including tax or payment conversion. Fix a reporting basis, then keep the original transaction values for reconciliation.

Separate setup, committed and variable cost

Setup costs happen before the first usable order. They can include configuration, catalogue correction, contract and privacy review, staff training, creative preparation, testing and migration. Capital and revenue treatment is an accounting question for the business's adviser.

Four cost types compared

Setup

When incurred: Before first order
Examples: Configuration, training
Key record: Capital or revenue
Budget treatment: Allocate visibly

Committed

When incurred: Contracted period
Examples: Subscriptions, retainers
Key record: Term, renewal, exit
Budget treatment: Include full term

Variable

When incurred: With activity
Examples: Per order, per refund
Key record: Unit and trigger
Budget treatment: Convert to scenario

Contingent

When incurred: Only if event
Examples: Chargebacks, reshoots
Key record: Cause, owner, basis
Budget treatment: Risk model line

Committed costs continue for the contracted period whether sales occur or not. Examples are subscriptions, retainers, minimum media commitments, support tiers and assigned staff capacity. Record term, renewal, cancellation deadline and any usage allowance.

Variable costs change with activity. Possible units include an order, payment, refund, shipment, creator sale, message, catalogue item or advertising delivery. State the unit and trigger. A percentage of gross order value should not be compared directly with a fixed monthly amount until both are converted into the same scenario.

Contingent costs arise only when something happens, but still belong in the risk model. Chargebacks, reshoots, urgent moderation, lost-stock correction, incident response, contract exit and manual refunds may not appear in an ordinary month. Give each a cause, owner and estimation basis instead of hiding them inside a broad contingency percentage.

Build the cost ledger

Include internal labour. Ask staff to record time for catalogue fixes, creator briefing, approvals, live cover, customer questions, refund matching, feed errors and reporting during a representative trial. Multiply recorded hours by the finance-approved loaded hourly cost. Do not substitute salary alone unless finance confirms that definition. For staff-hour evidence, time-record during a trial.

Use the National Living Wage as a floor and add employer National Insurance and pension for a loaded rate.

Creator compensation may include fees, commission, samples, usage rights, paid amplification and administration. The ASA and CAP influencer guide explains how payment, gifts, affiliate arrangements and editorial control affect advertising recognition. Budget the briefing, label check and monitoring needed for the actual arrangement; a creator invoice does not cover the retailer's own control work.

The table below gives indicative England cost anchors. It is a template for planning, not a supplier quotation.

Cost line	England anchor	What determines it
Card payment	Stripe UK published rate: 1.5% plus 20p per successful UK card charge	Card type, volume, refund policy, negotiated terms
Platform commission	No single England rate; TikTok Shop UK commission varies by category in current seller terms	Category, seller terms, campaign, returns
Creator fee	Quote-specific; ask for per-post, commission, retainer or hybrid terms	Reach, usage rights, exclusivity, format, samples
Media	Meta and TikTok ads are auction-based; no list price	Audience, objective, competition, creative quality
Software	Shopify Basic UK plan is £25 per month at the time of writing; verify current terms	Plan, users, transaction fees, add-ons
Staff time	National Living Wage is £12.21 per hour for 21 and over from April 2025; add employer National Insurance and pension for loaded cost	Role, hours, shift cover, employer costs

Use a formula that follows settled England orders to contribution

For a chosen period, calculate:

From settled revenue to ROI

Settled sales revenue excluding VAT
Minus product cost and fulfilment
Minus return handling and payment charges
Equals product contribution
Minus creator, media, software, staff
Equals incremental programme contribution
Divide by incremental programme cost for ROI

Settled sales revenue excluding VAT = completed order revenue - cancellations - refunds - sales taxes included in the reporting basis

Product contribution = settled sales revenue excluding VAT - product cost - outbound fulfilment - return handling - payment and order-linked charges

Incremental programme contribution = product contribution attributable to the programme - creator cost - media cost - software cost - incremental staff and supplier cost - other incremental overhead

ROI percentage = incremental programme contribution / incremental programme cost x 100

Do not calculate ROI when the denominator is zero, the attribution basis is undefined or material order states are missing. A negative numerator is a reported loss, not a measurement error to remove.

The formula is a template, not evidence that social content caused an order. Compare a declared attribution view with a separate decision estimate. Deduplicate platform, shop and analytics records by stable order identifiers where lawful and available. Report unattributed and conflicting records rather than forcing them into one channel.

Worked England example (monthly, figures exclude VAT):

Settled England orders to contribution

Gross orders1,000 at £36 including VAT = £36,000.
Cancellations at 2% = £720. Returns and refunds at 20% = £7,200.
Settled gross revenue = £36,000 - £720 - £7,200 = £28,080.
VAT included at 20% = £4,680. Settled revenue excluding VAT = £23,400.
Product cost = £9,360. Outbound fulfilment = £2,000.
Return handling = 200 returns at £6 = £1,200.
Payment charges = £750.
Product contribution = £23,400 - £9,360 - £2,000 - £1,200 - £750 = £10,090.
Creator cost = £3,000. Media cost = £2,500. Software = £500.
Incremental staff = 60 hours at £18 loaded = £1,080. Other incremental overhead = £300.
Incremental programme cost = £3,000 + £2,500 + £500 + £1,080 + £300 = £7,380.
Incremental programme contribution = £10,090 - £7,380 = £2,710.
ROI = £2,710 / £7,380 x 100 = 36.7%.
VAT noteif the business cannot recover VAT, add VAT on VAT-bearing costs. At 20% on £7,380, that adds £1,476 and reduces contribution to £1,234.

Treat refunds and returns as dated states

Revenue seen shortly after a campaign can overstate the contribution that remains. Keep orders in provisional, settled, cancelled, returned, refunded and disputed states. Choose a reporting lag that reflects the retailer's actual return cycle and show immature cohorts separately.

GOV.UK's returns and refunds guidance describes rights for online orders and the handling of standard delivery costs, with exceptions. The broader distance-selling guidance covers pre-contract information, confirmation and delivery for covered transactions. A legal reviewer should apply the current rules to the goods, offer and customer location.

Budget both the refunded amount and operational work: inbound delivery, inspection, repackaging, damaged stock, payment reconciliation and customer support. For example, 200 returns at £6 each is £1,200 per month. Source the return cycle from the retailer's dated order and refund records and payment-processor refund dates. Trade surveys can give context, but show the retailer's own sample size.

Avoid a flat return assumption where products or creator routes behave differently. Use the retailer's dated cohort evidence and show the sample size.

Keep customer pricing separate from programme cost

This section covers customer-facing fees only. The commercial budget asks what the retailer spends and earns. Customer-facing price review asks what the buyer sees and must pay. They interact, but one cannot replace the other.

The CMA's price-transparency guidance covers mandatory fees, taxes, drip pricing and partitioned pricing. Review the completed social journey, including product cards and linked checkout screens. A platform deduction charged to the merchant is not automatically a fee that can be introduced to the customer later.

Create a release check for the total public price, delivery charge, promotion conditions and stock. Budget correction and customer-remedy work if different systems can publish conflicting values. Do not count revenue from a route whose material pricing defect requires repayment until finance and legal owners have resolved it.

Compare pricing models on common scenarios

This section covers merchant deductions only. Model at least a low, expected and operational-stress case using the business's own demand assumptions. Vary order volume, average settled revenue, returns, creator commission, paid delivery, staff hours and error handling. Do not change several inputs without recording which one drives the result.

Convert every quote to cost for the same period and scope:

Scenario cost = setup allocation + committed charge + sum of each variable rate x relevant volume + expected contingent cost

Keep setup allocation visible rather than pretending the cash payment recurs. Show total cash requirement as well as the management-accounting allocation. Record what happens above included allowances, at renewal and on exit.

A revenue-share model transfers some volume risk but can become expensive at higher settled sales. A retainer provides predictable invoices but does not assure output or results. A subscription may exclude implementation, support or platform charges. A hybrid can combine all three. The decision depends on the measured route and binding quotation, not the label.

Budget data, controls and failure recovery

Pixels, server events and uploaded audiences create implementation and review work. The ICO's storage and access technology guidance covers cookies, pixels and similar methods under PECR and, where relevant, data-protection law. Include configuration, consent-interface work, notices, testing, rights handling and supplier oversight as separate lines.

Security is also an operating cost. The NCSC's small-organisation guide covers accounts, devices, backups and attack recognition. Budget named-user administration, authentication, safe recovery and out-of-hours escalation according to access and sales hours.

Set a reserve through scenarios, not an unexplained percentage. Identify a plausible event, such as a stale price, rejected catalogue group, unavailable checkout or lost administrator access. Estimate the affected hours, orders and supplier work from internal evidence. Keep the event outside base performance so decision makers can see both ordinary economics and resilience needs.

Distinguish cash, cost and tax

Cash timing can differ from recognised revenue or cost. Record supplier prepayments, platform settlement delays, refund timing, creator payment dates, VAT payment or recovery, card reserves and annual renewals. A profitable period on an accrual view can still require working capital.

HMRC's VAT record guidance explains purchase-invoice and VAT-account requirements. Reconcile budget categories to the accounts and retain the invoice evidence required for the adopted treatment. Do not assume a dashboard deduction is a valid VAT invoice.

Use separate columns for cash paid, accounting cost and recoverable tax. Ask the qualified reviewer how samples, gifts, mixed use, imported services, commissions and cross-border transactions should be handled. This article does not determine those questions.

Release an England budget decision range, not a single promise

The approval pack should show the base case, sensitivities, break-even input, cash requirement, missing evidence and stop conditions. A break-even calculation solves for the unknown using the business's contribution assumptions; it is not a sales forecast.

State which results are observed, allocated, estimated or supplier-quoted. Reforecast after the first settled cohort using actual invoices, staff time, returns and order states. Preserve the original assumptions so changes are explainable.

Before 2027 activity begins, refresh supplier quotations, tax advice, customer-price checks, creator terms and platform deductions. Stop or redesign the route if mature contribution remains negative, records cannot be reconciled, compliance work was omitted or the cash requirement exceeds the approved limit. A budget is useful when it exposes that decision early.

Common questions

What revenue should the budget use instead of views or checkout revenue?

Use settled orders, not views or checkout revenue. Apply the VAT and currency basis defined in the accounting boundary. Record actual invoice currency and the conversion method used in the accounts. Do not compare a sterling quote excluding VAT with a foreign-currency charge including tax or payment conversion.

How should returns and refunds be treated in the budget?

Treat refunds and returns as dated states. Keep orders in provisional, settled, cancelled, returned, refunded and disputed states. Choose a reporting lag that reflects the retailer's actual return cycle and show immature cohorts separately. Budget both the refunded amount and operational work such as inbound delivery, inspection, repackaging, damaged stock, payment reconciliation and customer support.

What should be included in the cost ledger?

Create one row per charge or internal resource. Minimum columns are supplier or owner, purpose, unit, quantity driver, rate source, currency, VAT treatment, fixed or variable status, commitment, invoice evidence, allocation rule and uncertainty note. Include internal labour, creator compensation and contingent costs with a cause, owner and estimation basis.
