Shopping mall GTO
Mall GTO submission from Shopify POS.
Our GTO app takes Shopify POS sales and submits them in the format each mall requires, every day. In Singapore it supports JEM and 313@somerset, and new malls can be added on request.

The problem
Who needs GTO submission?
Tenants in many Singapore shopping malls must submit daily sales to the mall, or to an agent the mall appoints, for GTO (gross turnover) rent. It is a condition of the tenancy agreement.
Missing submissions can lead to penalty fees or rental charged on estimated sales, which is usually significantly higher. Each mall also has its own file format and transfer method, so manual uploads grow with every outlet.

Questions
Asked often.
Which Singapore malls are supported?
JEM and 313@somerset, as published by WebCEO and checked 18 October 2026. The app also supports malls in Malaysia. For another Singapore mall, send us its GTO documentation.
What is GTO rent?
GTO is gross turnover. Where a tenancy agreement ties rent to an outlet's sales, the mall needs daily sales figures from the tenant, sent in the mall's own file format.
What if my mall is not on the list?
Contact us with the mall's GTO documentation or the mall person-in-charge. A one-time integration fee may apply, and we confirm the exact cost before work starts.
A mall is asking for a sample file. How do I get one?
Contact us and we will provide the sample file the mall needs.
What if a day's sales figure is wrong?
Send us your Shopify store domain. We request collaborator access to investigate and correct the submission.
The mall's POS technician says a GTO file is missing.
Create a manual job for that date in the app. If it happens again, contact us so we can investigate the cause.
