Next Engine is a service that helps centrally manage and automate the operations required to run multiple e-commerce stores. It provides over 200 features supporting the detailed tasks needed for e-commerce operations, including product registration, order management, purchase order management, and POS integration.
It integrates with e-commerce malls and shopping carts, of course, but also with a wide range of other systems, including warehouses, promotional systems, and core business systems.
In July 2018, it achieved the No. 1 position in the industry for adoption track record. As of 2024, over 6,000 companies have contracts, and it has been adopted by more than 50,000 stores.
Sites well suited to adopting Next Engine
Adopting Next Engine is well suited for e-commerce sites facing challenges such as the following.
- Increasing workload burden or human error at the operational level
- Aiming for full automation of e-commerce operations
- Struggling with managing multiple stores
Adopting Next Engine allows you to automate the tasks within e-commerce operations where "outcomes don't change no matter who does them." This helps reduce workload and brings you closer to full automation of your e-commerce site.
Next Engine can also consolidate wholesale orders and physical store inventory, not just e-commerce sites. If you're running multiple e-commerce stores alongside physical stores or offline orders, adopting Next Engine is especially recommended.
Benefits of integrating Next Engine with Shopify
Many people running an e-commerce site use "Shopify," a rapidly growing e-commerce platform. Even if you're running your e-commerce site on Shopify, integrating with Next Engine can help streamline operations and reduce time costs.
Here, we introduce the benefits of integrating Shopify with Next Engine.
Centralized management of orders, inventory, and shipping operations
Integrating Shopify with Next Engine helps with centralized management of order, inventory, and shipping operations.
Once Next Engine is integrated, everything from importing orders to sending thank-you emails and purchase order notification emails can be automated. By linking with warehouse, physical store, and core system inventory, quantities are updated in real time, reducing the risk of overselling that is common with online stores. Irregular changes such as cancellations and returns are also reflected, enabling highly accurate inventory management.
By integrating with a shipping label issuance system, you can also streamline the tasks needed for shipping, such as creating and sending shipping labels.
Streamlines multi-store operations
The biggest benefit of Next Engine is that it allows centralized management of multiple stores. If you have your own site set up on Shopify plus stores on e-commerce malls or physical stores, you would normally have to manage orders, inventory, and shipping separately on each platform. However, integrating Next Engine allows you to manage orders, inventory, and shipping for each store without having to check each platform individually.
This reduces the workload involved in running an e-commerce site, making it possible to operate multiple stores with a small team.
Reduces operational time
Another benefit of integrating Next Engine with Shopify is the reduction in operational time.
Next Engine offers a wide range of support features that make running an e-commerce site easier, including inventory management, product registration, payment service integration, ordering, and purchasing. You can also transcribe offline orders into slips through direct input in Next Engine or by importing CSV data.
This significantly reduces the time spent on e-commerce operations, freeing up time to focus on other initiatives such as marketing.
Precautions when integrating Next Engine with Shopify
While integrating Next Engine with Shopify can be expected to streamline e-commerce operations, there are a few precautions to keep in mind when integrating.
Here, we introduce the precautions for integrating Next Engine with Shopify.
It costs money
Integration with Next Engine is not free. Next Engine's usage fee is a base fee plus a usage-based fee.
The base fee is ¥3,000 (as of 2024), but the fee increases as the number of monthly orders increases. As a result, costs rise significantly as order volume grows.
When integrating with Next Engine, it's important to fully consider the cost implications, which are expected to fluctuate going forward.
There are integration limitations
The Next Engine and Shopify integration does not support product information syncing, which is available between Next Engine and some e-commerce malls. To sync product information, you need to export the product information registered in Next Engine as CSV data and import it into Shopify.
Note that some operations cannot be automatically synced in the Next Engine and Shopify integration.
