Vegas is a mail-order system operated by Forbis Co., Ltd. It allows features to be optimized to match the growth of your online shop. Its appeal lies in the ability to customize flexibly without being constrained by the system's own limitations, as is often the case with typical e-commerce carts, and it is used by e-commerce sites across a variety of industries.
Features of Vegas
Below, we introduce the features of Vegas.
Features Needed for E-Commerce Operations Provided as Apps
Its biggest feature is that all functions corresponding to e-commerce operations are provided as apps. Each function needed to run an e-commerce business — such as order receiving/placing, returns, and campaigns — is available as an app, and store owners can freely choose which apps to use.

Another feature of Vegas is the wide range of sales initiatives it can execute. It supports four patterns — initiatives for first-time buyers, initiatives for repeat buyers, point-based initiatives, and discount initiatives — making it possible to roll out detailed, customer-specific initiatives, such as "offer a special price to third-time buyers" or "include a bundled gift on the sixth purchase."
Generous Support from Implementation Consideration Through Operation
Vegas provides generous support from the implementation consideration stage through system development and operation.
| Phase | Support details |
|---|---|
| Implementation consideration phase | Organizing operational and system challenges and compiling requirements, calculating the scope, budget, and schedule for system replacement, selecting candidate development vendors, etc. |
| Development phase | Creating/changing workflows, supporting the formulation of business rules, creating operation manuals, supporting operational testing on the new system, rehearsing data migration, etc. |
| Operation phase | System master registration, data extraction/aggregation, data maintenance, product master registration, bulk order data registration, organizing operational issues, etc. |
Even after operation begins, you can receive support aimed at improving your service, such as considering the introduction of new technologies/products and adding or changing packaged software.
Advantages of Vegas
Here we explain the advantages of Vegas in detail.
The System Can Be Flexibly Customized to Match Business Growth
Because all the features needed to run an e-commerce business are provided as apps in Vegas, you can design the system by combining the apps you need to match the situation of your e-commerce site. If existing apps cannot handle a particular need, new apps can also be added.
With other e-commerce carts, it is not uncommon for a feature you want to use to be unavailable due to constraints on the system side. With Vegas, however, you can continue customizing the system toward realizing your ideal e-commerce site at any time.
Enables Omnichannel, Which Helps Improve the Customer Experience
Vegas makes it possible to achieve "omnichannel," in which multiple sales channels are linked together to reach customers in the optimal way. With omnichannel, responses such as "if a customer who visits a physical store finds that the product they want is out of stock, immediately arrange for it to be ordered from the e-commerce site and picked up at their nearest store" become possible.
This increases customer satisfaction and can be expected to improve repeat purchase rates.
You Can Combine a Variety of Sales Initiatives to Improve Repeat Purchase Rates and Expand Sales
Another appeal of Vegas is that you can freely combine and execute a variety of sales initiatives.
You can set detailed combinations of customer status and initiatives, such as "include a bundled gift on the third purchase," "free shipping on orders of 1,000 yen or more," "20% off on the second purchase," and "redeem 500 points for a gift."
Because you can present the optimal initiative to match each customer's status, you can achieve improved repeat purchase rates and expanded sales.
You Can Proceed While Receiving Support Toward Resolving Operational Issues
Another appeal of Vegas is that you can receive generous support aimed at resolving operational issues.
| Phase | Support details |
|---|---|
| Implementation consideration stage | Conducting interviews with each department about operational and current-system issues, and supporting the organization of operational and system challenges |
| Development stage | Support for formulating business rules, creating operation manuals, and conducting operational testing on the new system |
| Operation stage | Support for considering new technologies/products aimed at improving service, and organizing operational issues |
By receiving this support, you can build a system that addresses your operational issues down to the smallest detail. As a result, current challenges in your e-commerce business can also be resolved smoothly.
