Mercart is a cloud e-commerce platform offered by Mercart Co., Ltd. It is a SaaS-based e-commerce platform with a track record of over 1,600 sites adopted domestically. Because you can change plans as your business grows, it's a service well suited to businesses that want to start small with their e-commerce operation while keeping future growth in mind.
Mercart comes with the features needed to build a wide range of e-commerce site types, including general mail-order, subscription mail-order, single-item mail-order, and B2B mail-order (SaaS). It also has the unusual feature, rare among e-commerce carts, of receiving regular automatic system version upgrades, letting you run your e-commerce site while always using the latest features aligned with current trends.
One reason it's well regarded is its attentive support, from site launch through to operation after the build.

Benefits of Adopting Mercart

Attentive Support Is Available Even Before Site Construction Begins

A major appeal of Mercart is its attentive support structure. It offers extensive support covering a wide range of e-commerce operation needs, from selecting the optimal service and site design/construction to consulting and marketing support aimed at boosting sales.
After an e-commerce site launches, a dedicated team provides about a month of intensive support. For sales-boosting support, it also provides expert support for each area, including web advertising operations, content production, and use of social media and CRM.
Semi-Custom Site Construction Is Possible
Mercart also provides support for building your e-commerce site. Rather than relying solely on prepared templates, it carefully designs appropriate options and settings for each individual customer based on their business details and budget. You can also have Mercart create an appealing site design suited to your business, based on a hearing about your preferred base design.
Even if you're not sure what site design would be best, or you lack the skills to design your ideal site, Mercart can help you launch your site smoothly.
Mercart's Pricing Plans
Mercart's pricing plans are divided into three tiers: the Launch Plan, the Recommended Plan, and the DX Plan.
| Plan name | Launch Plan | Recommended Plan | DX Plan |
|---|---|---|---|
| Initial setup fee | 190,000 yen | 190,000 yen | 690,000 yen |
| Monthly fee | 49,000 yen | 99,000 yen | 199,000 yen |
| Expected scale | Up to 100 million yen in annual sales | 100 million to 1 billion yen in annual sales | 1 billion yen or more in annual sales |
(As of March 2026)
The Launch Plan comes with a minimal set of features and is best suited to building a small e-commerce site. The Recommended Plan is best suited to building a full-fledged e-commerce site. You can also add options such as customer engagement, analytics, and CRM starting from 3,000 yen per month.
The DX Plan is the most feature-rich plan. Unlike the other plans, it comes standard with CDP, CRM, and customer analysis functions, and can automate a broad range of complex marketing activities.
Every plan includes free 1-on-1 consulting support, through which you can receive, at no cost, help designing your approach to target customers, feature introductions, and proposals for identifying and improving on challenges.
Each plan can also come with an optional launch progress support add-on. This makes Mercart a comfortable choice even for e-commerce businesses building their first site, migrating carts, or feeling uncertain about progress management.
Case Studies of Mercart Adoption

Ringer Hut had been using a cart system with only the minimum functionality needed to sell products, and was dissatisfied with the lack of features for rolling out initiatives. When its previous site's cart system service ended, the company migrated to Mercart, which comes with the functionality to carry out a wide range of initiatives, and relaunched its site.
After the relaunch, by making use of numerous analytics features to roll out various initiatives, the company achieved a 215% year-over-year increase in a single month's sales.

Oshman's had been running its e-commerce site since 2007 using another company's package and, subsequently, ecbeing's packaged version. However, because an operations agency was in between, running costs were high, and because requests couldn't be communicated directly to the development side, the company found itself slow to respond.
After migrating to Mercart, the company redesigned its site with a simple, white-based look that's easy to use on smartphones. It also placed banners such as "seasonal features" and "original collaboration products available only here" near the top of the site, taking care to convey a look and feel true to the Oshman's brand. As a result, the company achieved up to a 140% month-over-month increase in member registrations compared with before the relaunch.
