What is OMS? (Order Management System)

An OMS is a comprehensive order management system that allows online stores to manage orders from every platform in one place. This includes channels like Shopee, Lazada, LINE, TikTok, and others (all channels), without the need to open multiple systems or manage them separately.

The OMS system helps streamline back-end processes such as order consolidation, inventory deduction, shipping label printing, carrier selection, and handling returns/claims. This makes work easier for the merchant, saves time, reduces errors, and allows the business to scale professionally.

The OMS can also:

• Integrate multiple sales channels and automatically pull SKU data.

• Manage inventory in real-time, with the ability to separate stock by sales channel.

• Support the sale of bundled/set products.

• Store customer data for reuse.

• Batch print orders for multiple carriers simultaneously.

• Connect with accounting systems (e.g., PEAK) to track income, expenses, and taxes.

• Consolidate chats from all pages into one place, speeding up sales closing.

The OMS is the heart of order administration for online stores that require an accurate, fast system, and want to reduce repetitive tasks.

Who is the OMS (Order Management System) suitable for?

It is suitable for stores that:

• Sell products across multiple online channels, such as Shopee, Lazada, TikTok, Facebook, LINE, etc.

• Have a high volume of orders and require a system to consolidate all orders in one place.

• Want to reduce time spent on back-end management (e.g., inventory deduction, order printing, carrier selection, etc.).

• Want to minimize errors resulting from manual data entry or management.

• Need to view sales reports and analyze best-selling vs. poor-selling products.

• Wish to connect with accounting systems like PEAK to monitor income, expenses, and taxes.

• Are expanding their business and need a back-end system that supports growth.

It is ideal for online store owners, order managers, or businesses that sell on multiple platforms.

Why Use an OMS?

In an era where online stores sell across multiple channels (e.g., Shopee, Lazada, LINE, TikTok, Facebook, etc.), managing orders manually or separately for each platform leads to:

• Wasted time

• Easy errors

• Inaccurate stock levels

• Shipping delays

• Missed sales opportunities

The reasons to use an OMS are:

• Consolidate orders from all channels in one place—no need to open multiple apps or backends. The OMS pulls orders automatically from every platform.

• Real-time stock deduction—inventory updates immediately upon order placement, preventing overselling and running out of stock unexpectedly.

• Print orders and shipping labels instantly—supports printing multiple orders at once from various carriers, eliminating redundant work.

• End-to-end order management—handle confirmation, shipping, claims, returns, and cancellations—all within one system.

• Reduce redundant work and minimize errors—automation reduces data entry mistakes or shipping errors caused by human error.

• Consolidate chats from all channels in one place—easy to reply, no missed customers, helps close sales faster.

• View sales reports and analyze best-selling/poor-selling products—allows for more accurate stock and marketing planning.

• Connect with accounting systems like PEAK—manage income, expenses, taxes, and close accounts easily in one place.
