Use AI across related entities. Do not mix unrelated clients.
A holding company, operating company, and related subsidiaries often need a controlled cross-entity review. Keep that work inside an approved entity group, preserve the ledger as the system of record, and require human review before a proposed accounting change.
Multi-entity analysis is useful when the entity scope is intentional.
Related entities often share vendors, management questions, cash constraints, intercompany activity, and reporting needs. Claude can help an accountant retrieve the approved detail, compare the numbers, and prepare a review package across those entities.
That does not mean a firm should put every client into one workspace. Do not mix unrelated clients. A cross-entity prompt belongs only inside a defined related-entity group where the firm is authorised to see the data and the accounting question genuinely crosses company boundaries.
Start with the entity map, not the prompt.
- 1. Define the related entities. Name the holding company, subsidiaries, operating entities, and any company that is out of scope for the review.
- 2. Confirm authority. Verify that the firm and the person running the work are authorised to access each company’s QuickBooks Online or Xero data.
- 3. State the question. Ask for a specific comparison, such as shared-vendor spend, intercompany balances, revenue by entity, or a consolidated close review.
- 4. Review evidence before treatment. Use transaction-level detail, reports, and supporting schedules to decide whether the item is an exception, reclassification, elimination, or a client question.
- 5. Approve entity-specific changes separately. A finding may span several companies, but a proposed entry or categorisation still needs human review in the ledger it affects.
Ask across entities without losing the evidence.
Shared vendor review
Compare software, contractor, travel, or other vendor spend across related entities. Show the transaction-level evidence behind unusual differences.
Intercompany preparation
Identify balances and transactions that may need an intercompany schedule, elimination workpaper, or accountant follow-up.
Cash and AR oversight
Review cash movement, overdue receivables, and collection risk across an approved group before preparing management commentary.
Entity close status
Prepare the exceptions, missing support, and open reconciliation work for each related entity before the consolidation review begins.
Management reporting
Draft a checked narrative that distinguishes group-wide movement from a result that belongs to one operating entity.
Budget and variance review
Compare entity performance against the relevant budget and explain what changed, without blending account structures or accounting decisions.
Cross-entity access is not an excuse for cross-client access.
Numbers Game scopes approved users and AI clients to the companies a firm names. That makes related-entity work possible without treating the entire firm portfolio as a common dataset. The firm can keep one entity read-only, exclude a sensitive entity, or remove a former client entirely.
QuickBooks Online and Xero remain the system of record. Claude can help retrieve, organise, compare, and prepare. The accountant decides what the evidence means and whether a proposed accounting treatment should be approved.
Avoid the shortcuts that make a multi-entity review less reliable.
Assuming similar vendors mean the same treatment
A shared supplier can have different contracts, entities, tax treatment, departments, or periods. Inspect the evidence before standardising a treatment.
Posting group logic everywhere
A consolidated insight is not an instruction to post the same entry in every entity. Review the proposed change in the ledger it affects.
Using one project for unrelated clients
Separate unrelated client work. The operational convenience is not worth weakening confidentiality or making the result hard to explain.
Treating AI output as a workpaper
Use the output to prepare a review. Retain the relevant reports, schedules, evidence, and accountant conclusion in the firm’s normal workpaper process.
