One accounting provider, several companies: agree how fees are billed

A group accounting engagement may serve several companies while sending one invoice to a parent. Before signing, identify the contracting party, companies receiving work and entities expected to pay. Ask the provider to make those relationships explicit. A consolidated sales quote does not establish that every affiliate is a client or may rely on every deliverable.

Give procurement and the accounting team the same entity list. Include the service start and end dates for each company. If one company joins later, state whether it requires an amendment and how onboarding is priced. Avoid charging work to an inactive affiliate merely because its billing details remain in the supplier system.

Request invoice lines that identify work performed for a particular entity and services benefiting the group. Separate an individual return or ledger from group coordination or consolidated reporting. The detail should be sufficient to explain the supplier charge without demanding a staff timesheet where the agreement uses fixed fees.

Ask how shared fees are calculated and whether the same work appears in both entity and group charges. Compare the total with the accepted proposal. A clear supplier billing schedule makes duplicate charges easier to detect and gives management a defensible record of what it purchased.

AICPA engagement guidance recommends identifying parties, services and payment terms. For a group, apply that to each named recipient and the payment arrangement. The supplier's allocation is a commercial schedule; it does not automatically determine the appropriate intercompany accounting or tax treatment.

Have the company's accountant and tax advisers determine how group costs should be recorded or charged among entities under the relevant facts and rules. Tell them what the provider actually performed and who benefited. Do not ask a billing clerk to settle a transfer-pricing or deductibility question by splitting an invoice evenly.

If internal reporting needs a particular breakdown, agree whether the provider can supply it from reliable records. Distinguish factual service detail from management's chosen allocation method. Where a split is an estimate, label its basis and assign an owner to approve it before it enters recurring reporting.

Specify what happens when an entity is sold, becomes inactive or adds a service. Identify the final covered period and any completion work billed afterward. Ask for credits or revised allocations to reference the original charge so finance can trace the change across companies.

Agree whether one entity's unpaid invoice affects service for others and have the contract reviewed where that exposure matters. The operational team needs to know which commitments could be interrupted. A group discount can create commercial dependencies that are absent from separately contracted engagements.

Review a sample invoice using the proposed entity and service structure. Confirm purchase-order references, billing contacts, currency and tax treatment with the appropriate owners. Resolve any system limitation that would force the provider to omit the detail your group requires.

At the first billing cycle, reconcile the total to the contract and check that each company receives the agreed support. Keep the accepted schedule and later amendments together. The next finance employee should be able to explain a shared fee without relying on the person who originally negotiated the group arrangement.
