Connecting to 3S POS - Order Ingestion
How to link Slerp with 3S POS and configure your stores for online ordering.
Overview
To connect Slerp to 3S POS you need to do the following:
- In Controls, create all the stores you want to link to 3S POS.
- In Controls, complete inventory setup (menu, products, modifiers) for each store.
- Contact 3S POS to activate the Slerp channel and obtain a Slerp Location Channel ID for each store.
- Contact Slerp and pass over your Slerp Location Channel IDs so that we can finalise the setup.
- In Controls, ensure all products have their SKUs set before placing a test order. This must be done manually.
Activating the Slerp Channel in 3S POS
Contact 3S POS to request activation of the Slerp channel.
Send an email to support@3s-pos.com. Your email should request the following:
- That they enable auto-accept for the Slerp channel
- A Slerp Location Channel ID for each store you want to connect
- A list of all products and their SKUs
A Slerp Location Channel ID is a unique identifier for a store and the Slerp channel. You will need one for each store you want to connect to 3S POS.
For each store, include:
- The Slerp store name
- The store address
Here is an example email you can use:
Subject: Slerp Channel Activation
Hi 3S POS Support,
I would like to activate the Slerp online ordering channel for my business.
Business name: [Your 3S POS Business Name]
Please could you:
- Enable auto-accept for the Slerp channel.
- Provide a Slerp Location Channel ID for each of the following stores:
- [Slerp Store Name] — [Store Address]
- ...
- Provide a list of all products and their SKUs.
Thank you,
[Your Name]
Pass Product SKUs to Slerp
Once you have received your Slerp Location Channel IDs, pass them to Slerp so that we can complete the setup.
Set Product SKUs
Before placing a test order, you will need to make sure that all products have their SKUs set in Controls. This must be done manually.
How to find your Product SKUs
If 3S POS are unable to provide a list of SKUs directly, you can export them from the POS using the Menu POS Item ID report.
To access the report, navigate to the Reports tab on either the till or via the web interface. From there, go to Stock Report and run the Menu POS Item ID report.
To save the report, click the floppy disk icon and select your preferred format. Excel is recommended.

Place a test order at the new location
To verify that the integration has been set up correctly, place a test order at the new location and confirm the following:
The order appears in 3S POS and contains:
- The Slerp order reference
- All products from the order
- The order is identified as a Slerp order
The order was auto-accepted.
Order status updates are relayed back to Slerp for the following:
- Ready for Collection
- Fulfilled
- Cancelled
