About Lassou

Lassou is a marketplace - platform where vendors can come together to sell their products or services to a curated customer base. All marketing and operations are managed by us. The vendors own the products and also manages the complete end-to-end fulfilment process. The description and inventory of the goods, and processing of the orders, is managed entirely through an integration with your e-commerce platform, and there is no manual intervention required on your part after the initial set up. A manual option is available also. 


We plan to promote the site and it's product range across all organic and paid advertising channels, including Google, Facebook and email.

Regarding the commission:  the pricing structure will be 20% commission on product revenue only (15% on soft drinks and No-Abv drinks). This excludes VAT and Shipping. We do not charge a minimum listing fee at this stage, although plan to implement one from April onwards at £49 per month. 

We will waive the £49 monthly fee for the first 6 months, as appreciation for your support as an early pre-live seller. Thank you for being willing to onboard at this early stage.


Each order customer place shall be deemed to be an offer by the customer to purchase the goods and/or services specified within it subject to the Terms of Service and the applicable details on the product page.

No order shall be deemed to be accepted by the Seller until we (acting as the commercial agent of the Seller) issue an acknowledgement email of your order. The contract between the customer and a Seller (also called a merchant or brand) will relate only to those goods and/or services notified in the email acknowledgement of order.

Sellers and customers both acknowledge and accept that your product’s Rating and Review will be publicly available for viewing on the Site.

We are not responsible for checking or editing the Reviews or Ratings on the Site, but will from time to time undertake checks of the content that has been posted. If we come across any reviews which, in our absolute discretion, are illegal, defamatory, offensive or obscene then we reserve the right to immediately remove such posts without notice.

We will investigate any Review which is reported to us as being illegal, defamatory, offensive or obscene and take whatever action we deem reasonably necessary in relation to that Review.
You agree to indemnify and hold us, our affiliates (and their respective employees, directors and representatives), harmless against any claim or action brought by a third party, arising out of or in connection with any Reviews or Ratings left by you on the Site.

The potential is great but a lot depends on you. Like many marketplaces, your order volumes will depend on what you put in: your products, product descriptions, pricing, shipping charges, product images...all of these factors and more will have a significant effect.

We offer advice on every aspect and will work particularly closely with you on the set-up to maximise your potential. You also need never receive more orders than you can handle. We have a very simple way for you to set your inventory levels.

The “My Account” page allows you to edit your Seller information, including your profile picture, banner image, and all the business information relating to your Seller account.


Key shop elements to address:

The banner Image: Upload a single image that represents the style of your brand and makes a strong first impression on shoppers. The ideal dimensions of the image are 2400 x 900 px, and we strongly advise you to adjust the dimensions of the banner for the best presentation of your shop. You can upload an image in any dimension, and then crop it within the platform. Here you can see an example of a banner displayed on the Seller Profile Page.

Brand Logo: We recommend that you upload a brand logo image with the dimension of 165x165 px.  Your upload an image in any dimension, and edit within the platform if necessary. Avoid large-sized photos, high-resolution images, and uncompressed images as these can drastically reduce the page load speed, which negatively impacts on the customer experience.

Brand Profile Image: We recommend that you upload an image with the size of 160 x160 px. Too large image files can take a long time to load. You can upload an image of any dimension, and then adjust this in the platform afterwards.

Shop Short Description: Share a brief welcome message with shoppers, tell them more about yourself and what you are selling. The Short Description will appear on the Lassou website on each of the product landing pages that you sell on Lassou. Here is an example of a product description.

Detailed Shop Description: Upload videos or photos and share the story behind your products, how your business came to be, and what your vision is for your brand. This is your opportunity to tell your brand story in a unique and authentic way so that the Lassou customer can learn about and engage with your brand.

You are able to use HTML code to embed images, videos and customer styling into the Description tab.

The Detailed Shop Description will appear on your dedicated Seller Profile Page. Here is an example of how it will look to the customer. 

Shop Policies: Here you will need to outline all of your policies for shipping, returns, exchanges, payments, custom items, or any other guidelines that are important for shoppers to know before they make a purchase of your products on Lassou


“If you have the courage to start, you have the courage to succeed.” Mel Robbins

Creating a product listing is the first step to getting your products in front of potential buyers. We have a range of tools and options to help optimise the appearance of your products on Lassou. 

Adding new products to your new Seller store on Lassou is easy and relatively fast. We have multiple ways how to add the products to your store, including:

1. The easiest, fastest, and best way to integrate your products is by synchronising your existing eCommerce store with Lassou store. We support several different eCommerce store integrations. Contact us to learn more. 

2. Manually add products using the “Add Product” from Lassou Seller Portal.

3. Upload your products as a bulk upload via CSV file from Lassou Seller Portal.

Creating a listing is the first step in getting your item in front of buyers. 



Add products to your shop by clicking on “My Products” - “Product listing”.

In the “Product listing” page click on “Add Product” and fill-up the required information. See the example of adding the product by clicking here.

By clicking on ••• dots from “Action menu” you can add, and edit your product, disable and view the product in-store anytime you need. Under this menu, you can find all the product-related information. Also, you can synchronise the product with the product information in your existing e-commerce store. See the example of adding the product by clicking here.



Enter the details in the given fields of the product form. See the example screenshots below. 

Tip: Item listing photo

We highly recommend uploading an image with dimensions of 1024x1024 pixels wide. Square images are best for the design style of Lassou. When it comes to image size, bigger isn't always better, as uploading multiple large images can affect site performance. If you're adding multiple photos to a page, keep your overall page size in mind. The dimensions of the original image you upload to your site can have a significant impact on how it displays. 


If you want to add your product as a bulk, go to “More Action” and click on “Add a product by CSV”. This way you can add a product and also bulk edit of your products. See the example here.

When you are adding products via CSV file, please keep in mind that the formatting of the file must be exactly as an example provided and available for download on the product upload page. All information included an example of the CSV file you can find in “Add a product by CSV” section.

For inserting images to the following spaces, you need to get the public URL which can be accessed from anywhere. Further, you need to enter that public URL into the source code. Please refer: here

This action will give you a pop-up. Here you need to enter the following code:

<img src="path of image">

Please refer: here

You need to enter the public URL of the image in place of the text ‘path of image‘.

See example: here and here


How to get the public URL of the image?

If you want to upload a local image to these spaces, you first need to upload the resource/image to the Cloud like on CDN (Content Delivery Network), Dropbox, etc.

Order Management - Lassou Seller Portal

The way that you manage the fulfilment of orders that you receive on Lassou will depend on the method that you used for uploading products to your Lassou store. 

When using the preferred method of Syncing your existing e-commerce store, the orders received on Lassou will be sent directly into your existing e-commerce store, such as Shopify.

In this case, you will use the functionality in your e-commerce to receive, process and manage the status of the orders that you receive from Lassou. 

When you change the fulfilment status of the order in your e-commerce store backend, the change will be reflected in the Lassou Seller Portal, and the customer will be informed. You will not need to log in to the Lassou Seller Portal to manage orders when you are using the Synching based set up. 


If you are not using the Synching based set up, you will need to log in to the Lassou Seller Portal to manage your orders. 

When an order for one of your products is made on Lassou, you will first of all receive an email with the order details. When you receive the email, you will need to log-in to Lassou Seller Portal.

Go to your seller panel and click on “Orders” > “Order Listing” > “View.” From here you can manage the order status. See an example here.

Click ••• dots from “Action menu” to view the order details, and enter the relevant delivery information. See an example here.

Once the order has been fulfiller, you will need to mark the order delivery status to “Fulfilled”. 

Once the order has been delivered, you will need to mark the delivery status as “Delivered”, enter the delivery date & submit.

Again, if your existing store has been linked with Lassou store, you don’t need to do anything. Once the product is delivered to the customer, the fulfilment status will be automatically updated upon confirmation of the delivery company.

Sellers are obligated to complete a sale with a buyer. However, we understand that there may be certain circumstances in which orders need to be canceled.

If a buyer asks you to cancel an order and you have not yet shipped and confirmed the shipment, you can cancel it:

Using Shopify Connector:
Log-in to your Admin Shopify Dashboard got to “Orders” > “More Action” choose the reason of the cancellation and click on “Cancel Order
See an example here.

Using Lassou Seller Dashboard:
Log-in to your Seller Dashboard, go to “Orders” > “Order Listings” choose the order you need to cancel and press “View” from the action menu. Further, clicking on the Raise RMA Request button in the Order detail page, admin can initiate the refund request.
See an example here.

When you cancel an order, Lassou automatically updates the order status in the buyer's Lassou account and sends an email notification to the buyer. Both cancellations and returns are a normal part of most sales operations.
