Common Mistakes Businesses Make in GTO Audits – And How to Avoid Them

Gross Turnover (GTO) audits are a routine part of doing business for many retail and F&B tenants in Singapore shopping malls. These audits are not just a formality—they are often a contractual obligation under your lease agreement and must be done accurately and punctually to maintain a smooth relationship with your landlord.

However, many businesses—especially new tenants or SMEs—make common mistakes that can lead to delays, penalties, disputes, or even the loss of tenancy rights.

This article outlines the most common mistakes businesses make during GTO audits and provides practical tips on how to avoid them, so you can stay compliant, protect your tenancy, and maintain your business reputation.

What is a GTO Audit?

A GTO (Gross Turnover) Audit is an independent review conducted by a licensed auditor to verify that the sales revenue (gross turnover) reported to your landlord is accurate and complete. This is especially important in lease arrangements where rent includes a variable component based on turnover—often seen in shopping malls such as Junction 8, Jewel Changi, Compass One, NEX, and Bedok Mall.

After the audit, the auditor issues a GTO Certificate confirming the validity of your sales figures.

Mistake 1: Poor Record-Keeping

Why It’s a Problem:

Inaccurate, disorganised, or missing records make it hard for auditors to verify your reported sales. This not only delays the audit but can also trigger red flags about underreporting.

Common Signs:

• Incomplete or missing POS data

• Unmatched cash register summaries and bank deposits

• Gaps in credit card settlement slips

• No reconciliation between online and in-store sales

How to Avoid It:

• Use a modern cloud-based POS system with daily sales tracking

• Keep monthly reconciliations between sales and bank deposits

• Save all receipts, invoices, refund slips, and credit card reports

• Maintain both soft copies and backups

Mistake 2: Not Understanding Lease Requirements

Why It’s a Problem:

Many tenants are unaware of the specific GTO audit conditions in their lease, such as deadlines, definitions of turnover, or exclusions (e.g., GST, refunds).

This leads to late submissions, wrong reporting formats, or underreporting due to excluded revenue streams.

How to Avoid It:

• Read your lease carefully and clarify any uncertainties

• Know your reporting frequency – monthly, quarterly, or annually

• Understand how your landlord defines gross turnover

• Keep a checklist based on your lease to guide your reporting

Mistake 3: Delaying the Appointment of an Auditor

Why It’s a Problem:

Leaving the auditor appointment to the last minute can result in missed deadlines—especially during peak audit season (Jan–Mar). Some landlords enforce penalties for late submissions or may refuse to accept unaudited sales figures.

How to Avoid It:

• Engage an auditor at least 2–4 weeks before your reporting deadline

• Choose a firm with GTO audit experience for your mall (each has its own template and requirement)

• Work with an audit firm that offers prompt turnaround times and can guide you on compliance

Mistake 4: Underreporting Sales (Intentionally or Accidentally)

Why It’s a Problem:

Whether due to honest mistakes or deliberate omission, underreporting can lead to penalties, legal issues, and termination of lease. Landlords take GTO reporting very seriously, especially when rent is partially based on performance.

How to Avoid It:

• Reconcile all sales channels, including:

  • Online orders (e.g., Grab, Deliveroo)

  • Walk-in POS sales

  • QR code and e-wallet payments

  • Credit card terminals

• Double-check refunds and discounts are documented and justifiable

• Let your auditor validate your reporting before submission

Mistake 5: Submitting the Wrong Format to the Landlord

Why It’s a Problem:

Some shopping malls require sales reports or GTO certificates in specific formats. Submitting reports incorrectly can cause rejection and require rework.

How to Avoid It:

• Ask your landlord or mall management for their GTO submission template

• Check if they need monthly breakdowns, daily summaries, or GTO percentages

• Make sure your auditor issues the certificate in the requested layout

Mistake 6: Not Reconciling Between Sales and Bank Deposits

Why It’s a Problem:

If sales revenue doesn’t match the amount deposited into your bank account, it raises suspicion. Auditors must trace reported turnover back to your bank, so any shortfalls or gaps need explanation.

How to Avoid It:

• Reconcile daily POS sales with:

  • Bank deposits

  • Credit card settlements

  • E-wallet payment statements

• Document any timing differences (e.g., next-day deposits)

• Provide full bank statements to auditors for transparency

Mistake 7: Ignoring Online Sales and Third-Party Platforms

Why It’s a Problem:

Some businesses forget to include online sales or third-party revenue from food delivery apps, e-commerce platforms, or event marketplaces—especially if they are operated separately from the main store.

How to Avoid It:

• Include sales from GrabFood, Foodpanda, Shopee, Lazada, etc.

• Maintain monthly statements from each platform

• Clarify with your landlord if online sales should be part of GTO (some leases require it, others don’t)

Mistake 8: No Internal Review Before the Audit

Why It’s a Problem:

Sending data straight to the auditor without internal checks may lead to easily avoidable errors, which wastes time during the audit and increases the chances of negative findings.

How to Avoid It:

• Do a self-review of all sales reports before handing them over

• Match POS totals with bank deposits

• Confirm refund and discount policies were applied correctly

• Address missing data or irregularities internally

How a Good Auditor Can Help
