In recent years, selling on multiple e-commerce platforms has become a popular trend. Instead of selling on just one platform, many shop owners are expanding to Shopee, Lazada, and TikTok Shop to reach a wider customer base.

Ms. Lan Anh, 35 years old, is one of them. She has been running an online women's fashion business for almost 3 years and currently sells products on all three platforms. Thanks to effectively utilizing traffic from these platforms, her store has stable revenue and a high rate of returning customers.

However, as orders began to increase, multi-channel selling also brought about problems she hadn't anticipated.

As orders increased, management started to become complicated.

Every day, Lan Anh has to process around 40-60 orders from three different platforms. The job seems simple, but in reality, it's quite complicated.

Every morning, the first thing she has to do is open the management systems for each floor one by one:

• Shopee Seller Center
• Lazada Seller Center
• TikTok Shop Seller Center

She needs to check for new orders, print shipping documents, cross-check product information, and confirm orders.

Switching back and forth between multiple systems takes up a lot of her time. Sometimes, just checking orders alone takes hours each day.

Multichannel sellers often have to check orders across multiple platforms.

Multichannel inventory: a major painpoint for online sellers.

Lan Anh's biggest challenge wasn't getting orders, but managing inventory when selling on multiple platforms .

Her store has about 50 clothing styles, each with many different sizes and colors. The total number of actual SKUs reaches hundreds of variations.

The problem is that each e-commerce platform manages its inventory independently .

Here's a real-world example:

My actual inventory is 50 products , but the items displayed on the platforms are different:

• Shopee: 30 products
• Lazada: 30 products
• TikTok Shop: 30 products

If a product sells well on multiple platforms simultaneously, the total number of orders may exceed the actual inventory in the warehouse.

At that point, she was forced to:

• Cancel order
• Contact the customer to exchange the product.
• Sorry, it's out of stock.

This directly impacts the shop's rating and customer experience.

Warehouse staff also faced difficulties processing orders.

As the number of orders increased, Ms. Lan Anh hired more warehouse staff to help with packing and preparing goods.

However, because the order was placed on multiple different platforms, preparing the goods became complicated. Staff frequently had to ask:

• Which exchange is this listing from?
• Where is the order code?
• What products need to be retrieved from the warehouse?

Just comparing the order with the products in stock takes a considerable amount of time.

During peak periods, errors in packing or preparing goods are more likely to occur.

When tax regulations change, issuing invoices becomes even more complicated.

Besides order and inventory issues, Ms. Lan Anh also faces the requirement to issue electronic invoices when customers need VAT invoices.

Previously, whenever a customer requested an invoice, she had to:

1. Reopen order information on the platform.
2. Enter data into the electronic invoicing software.
3. Double check the product and quantity.

The process isn't overly complicated, but as the number of orders increases, manual data entry can easily lead to errors and be time-consuming.

She realized that if she wanted to continue expanding her business, she needed a system that would connect all the sales processes together.

GTG CRM – a solution to centralize all sales activities.

After researching various multi-channel sales management tools, Ms. Lan Anh decided to try GTG CRM .

What caught her attention was that this system not only manages orders, but also connects inventory, products, and invoices all on the same platform.

Create a warehouse in the system.

The first thing she did was create a warehouse in GTG CRM .

She entered the basic information such as:

• Warehouse name
• Warehouse address
• Warehouse Manager

As a result, all subsequent inventory entry and exit activities are recorded in the system.

Create products and SKUs

Next, she imported all the products into the Product Center .

Each product is assigned a unique SKU code, for example:

• DAM-LUA-D1
• AO-KHOAC-K2
• QUAN-JEAN-J3

Thanks to SKU codes, the system can identify the same product even if it's sold on different platforms.

This allows for more accurate inventory management.

Connect Shopee, Lazada, and TikTok Shop platforms.

After setting up inventory and products, she connected GTG CRM to her sales accounts on e-commerce platforms.

Once the connection is complete, simply press the "synchronize" button, and the order from:

• Shopee
• London
• TikTok Shop

They are all synchronized to a single interface.

Orders are consolidated in a single location.

The order processing procedure has become simpler.

After using GTG CRM, Ms. Lan Anh's sales process changed significantly.

New procedure:

1. The order appears in the GTG CRM dashboard.
2. She changed the order status to " awaiting pickup".
3. Warehouse release form generation system
4. Warehouse staff prepare products according to the order.

As a result, warehouse staff no longer need to check each floor individually, but can work on a single interface.

Electronic invoices are automatically generated.

Another feature that helps Ms. Lan Anh save time is the automatic generation of electronic invoices .

You only need to set it up once in the settings:

• Invoice creation time
• Invoice status
• Default invoice template

After the order is confirmed for shipment, the system will generate the corresponding invoice.

If the order quantity changes, GTG CRM also supports automatic invoice adjustments , helping to ensure more accurate tax declarations.

Results after 6 months of using GTG CRM

After using the system for about six months, Ms. Lan Anh noticed many significant changes:

Save time

Previously, she had to spend many hours each day checking orders on each platform. Now, everything is centralized on a single dashboard.

Savings: 3–4 hours of work per day

Accurate inventory management

Inventory management has become more accurate. The system automatically updates stock quantities after each order, significantly reducing over-selling.

Cancellation rate decreased: from 8% to 2%.

Improve reviews

Ratings on the platforms also improved due to reduced order cancellations and more accurate delivery.

Employees work more efficiently.

Her warehouse staff also work more efficiently because they no longer need to manually cross-check orders as before.

Conclude

Lan Anh's story is a prime example of the challenges many multi-channel sellers are facing.

When orders are few, manual management might still be manageable. But as the number of orders increases and sales increase across multiple platforms simultaneously, the lack of a centralized management system will make business operations chaotic.

This allows sellers to operate their stores more efficiently and focus on business development instead of dealing with manual tasks.
