Gross Turnover (GTO) Audit/Sales Turnover Audit in Singapore
What is a GTO Audit?
A GTO Audit (Gross Turnover Audit) is an independent review and verification of the gross sales reported by a retail tenant. In many retail lease agreements, especially in shopping malls and premium retail locations, rent is structured with a base rent plus a variable component that is tied to the gross turnover (sales) of the business. This ensures that landlords share in the success of the tenant’s retail operations.
To ensure transparency, landlords often require tenants to submit their sales figures periodically — and to have these figures certified by an independent audit firm.
Other Common Terms

All of these refer to essentially the same process — auditing the revenue reported by a tenant to verify its accuracy and completeness, in accordance with lease agreement terms.

-
You are a landlord or property manager who wants to ensure the accuracy of your tenants’ reported turnover.

GTO Audit Workflow
Here’s how the typical GTO Audit process works at Koh & Lim Audit PAC:
1. Engagement & Scoping
We start by understanding your lease agreement terms, the scope of work, and the audit period. We will identify how “gross turnover” is defined and any inclusions or exclusions (e.g., GST, refunds, etc.).
2. Data Collection
We request supporting documentation such as:
-
Daily and monthly sales reports
-
POS summaries
-
Bank statements
-
Refund reports
-
Inventory movement (if relevant)
3. Fieldwork & Review
Our audit team will analyze the sales data, perform reconciliations, review internal processes, and assess consistency in reporting.
4. Audit Report Issuance
Once the verification is complete, we issue a GTO Certification Letter or Sales Turnover Report signed by our licensed public accountants.
This report is typically submitted to your landlord as proof of compliance.
