Full invoicing application audit

Who this is for

Controllers, CFOs, and accounting firm partners who need independent evidence that invoices are applied correctly before year-end sign-off or after an external auditor has raised sampling questions.

Result

You receive a findings memorandum, a schedule of proposed adjusting entries where needed, and a walkthrough file that your statutory auditor can reuse. We state what was tested, what held, and what remains open.

Scope included

• Selection of supplier and customer invoice samples across the period
• Tracing to purchase orders, goods receipts, delivery notes, or contracts where available
• Cut-off testing around month-end and year-end
• Review of credit note and debit note applications
• Assessment of suspense or clearing accounts used for unmatched invoices
• Closing meeting with finance leads

Excluded

• Full statutory financial statement audit
• Tax filing preparation
• Day-to-day invoice data entry
• Software configuration or billing system rebuilds

Provider and process

Fieldwork is led by an API Route Grid engagement manager with a supporting reviewer. We begin with a kickoff to map your invoice routes, then sample and test, then draft findings for your comment before the final memorandum.

Timeline and location

Most single-entity engagements in Bangkok finish in five to twelve working days once complete invoice packs are available. Multi-entity groups add time for intercompany invoice applications. We work at your office, our Rama IV meeting rooms, or a hybrid of both.

Preparation

Please prepare open invoice registers, period-end close checklists, prior auditor queries on invoicing, and access to supporting papers. If binders are paper-based, reserve a quiet table for sampling.

Pricing basis

Fees reflect monthly invoice volume, number of legal entities, language of source documents, and whether prior-year working papers exist. See Rates for starting ranges, then request an audit for a scoped estimate.

Next step

Send entity count, period under review, and approximate invoice volume through the contact form. We reply with clarifying questions and proposed fieldwork dates.
