A first-period review can show whether an accounting provider turns source records into accurate, understandable outputs under the proposed working process. The exercise should use the buyer's approved scope and qualified finance review. It is not a reason to let an untested provider make unrestricted changes to live records or take control of payment decisions.

## Choose a representative reporting period

Select records that reflect routine transaction types and a manageable number of known exceptions. Identify the starting balances and what has already been accepted. Where a sandbox or copied dataset is suitable, preserve a clear distinction from live books and control any later posting.

State what the exercise tests: document handling, reconciliations, query management, review and reporting. A clean sample of simple transactions may not establish capability for inventory, intercompany activity or other complexities in the wider engagement.

## Use the proposed team and workflow

Ask the actual preparer and reviewer to perform the work through the channels proposed for recurring service. Confirm access permissions and buyer approval points. A demonstration prepared by a senior sales specialist may not reveal the quality of the team that will maintain the accounts each month.

For example, include an unresolved source-document question and observe how it is logged, explained and escalated. The provider should not invent a treatment or silently force a balance to agree simply to produce a complete-looking report.

## Review the evidence behind the output

Have a qualified finance owner trace important balances and adjustments to supporting records. Check whether the reporting pack identifies limitations and next actions. Ask whether the buyer can retrieve the working files and understand the review trail without relying on a verbal explanation from one individual.

Test the query and correction process. A provider's willingness to examine evidence and correct work is important, but distinguish normal review from repeated failure to meet agreed requirements. Record the cause and the specific change needed.

## Approve a bounded operating scope

Document what passed, what failed and which complexities were not tested. Require a targeted repeat where a material process or team changes. Confirm that live-record updates follow the buyer's approval controls. A successful first period should support a specific accounting appointment and an improved close process, not a blanket assumption that the provider can perform every specialist financial role or remove all review responsibility from management.
