Scope a balance-sheet substantiation project account by account

Provide the prospective accountant with a dated trial balance and identify the entities, currencies, and accounts to be assessed. State the reason for the project, such as a new controller's review, financing preparation, or a backlog of unsupported balances. Define whether the assignment covers all balance-sheet accounts or a specific population with known concerns.

Ask the provider to explain what substantiation means for each account. A cash reconciliation, a contractual deposit assessment, and an estimate review need different evidence. PCAOB AS 1105 distinguishes assertions including existence, completeness, valuation, rights, and presentation in covered audits. Those categories can help scope the questions, without turning a preparation project into an audit opinion.

Require an account inventory showing the recorded amount, supporting source, reconciliation or assessment method, preparer, reviewer, and conclusion. Identify accounts needing technical judgment or specialist input. A worksheet that merely repeats the ledger amount does not establish support. Ask for a sample deliverable structure before engaging the provider, without requesting confidential client material.

For a hypothetical $75,000 deposit account, the project might require an itemized agreement register, proof of payments, return conditions, settlement history, and the accountant's classification and recoverability assessment. The agreed output should explain the $75,000 population and any unsupported portion. A single signed-off total would not satisfy that scope.

List the company owners responsible for contracts, statements, invoices, and operational confirmations. Agree what reconstruction the provider will attempt and how additional work is approved. Historical source recovery can dominate the effort when records are incomplete. A fixed fee should state the assumptions and deliverables that support it rather than imply unlimited reconstruction.

Keep unsupported amounts visible with their nature, period, missing evidence, and next action. The provider should distinguish a confirmed error from an unresolved question or estimate. Ask who can approve accounting conclusions where evidence cannot be recovered. Moving every residual to miscellaneous expense or equity should never be the project's unspoken completion method.

The scope should identify whether the provider only reports findings, proposes journals, posts approved corrections, or also updates dependent reports. Require a change register linking each correction to evidence and approval. Have the responsible accountant assess the period and any effect on issued statements or filings. A substantiation project can reveal issues beyond its original reporting date.

Agree how current bookkeeping continues while the review proceeds. Preserve the source snapshot used by the project and reconcile later activity separately. If the live ledger changes, the team needs a bridge between the reviewed balance and the current account. Otherwise the provider can finish an accurate historical schedule that no longer explains the balance management is viewing.

Review the account inventory, completed schedules, proposed and posted corrections, and unresolved-item register together. Define acceptance by the evidence and conclusions delivered, not by forcing every account to receive a clean label. A supported limitation may be an honest project outcome that still requires a management decision or further specialist work.

Require a handoff showing which schedules can become recurring close controls and who will maintain them. Retain the accepted reporting-date package and any bridge to current balances. The engagement should leave the company able to explain each scoped account, identify what remains uncertain, and continue the review without depending on the project's original preparer.
