Gravity Hub is an order-operations SaaS platform for multi-channel merchants. Its core goal is to bring product management, order processing, warehouse routing, shipping labels, and tracking updates into a single workspace. The site explicitly supports connecting Shopify and Amazon, allowing orders to be synced into one unified backend. It is a good fit for self-fulfillment merchants who do not want to keep switching between multiple platform dashboards.
The platform consists of PMS, OMS, and a planned WMS. The PMS is used to centrally manage the product catalog and push changes to ecommerce stores, reducing duplicate data entry and inconsistencies across channels. The OMS handles a unified order inbox, fulfillment, and delivery tracking. On the logistics side, Gravity Hub has built-in support for USPS, UPS, FedEx, and DHL, allowing users to compare shipping rates, print labels in bulk, and automatically sync tracking numbers back to Shopify and Amazon after orders are shipped. Warehouse routing can automatically allocate orders based on inventory, region, cost, or speed, while also allowing manual overrides.
The official website shows a 30-day free trial with no credit card required. The terms state that some features require a paid subscription and will be billed periodically through a linked payment method, but no specific plan pricing, order-volume limits, or separate label/usage fees are disclosed. The refund policy is relatively clear: after canceling a paid subscription, refunds are issued proportionally for the unused portion, but payment processing fees, bank fees, foreign exchange costs, chargeback-related fees, and non-refundable taxes will be deducted.
The main advantage is its focused use case, especially for Shopify and Amazon sellers who fulfill orders themselves across multiple channels. Order aggregation, bulk label printing, tracking sync, and warehouse routing all address frequent operational pain points. The drawbacks are also clear: the WMS is still marked as coming soon, so its full warehousing capabilities remain unproven; the currently confirmed sales channels are limited; and pricing is not transparent, making it hard to estimate costs at scale in advance. The terms include extensive limitations around third-party services, availability, and liability, meaning merchants need to bear the account and cost risks associated with platforms, carriers, and payment processors themselves.
Gravity Hub is better suited to small and midsize ecommerce teams that already operate Shopify/Amazon stores, fulfill orders themselves or ship from multiple warehouses, and want to unify shipping labels and order workflows. For sellers that rely on domestic Chinese platforms, local couriers, Alipay/WeChat Pay, or Chinese-language support, the site does not provide relevant compatibility information. Access from mainland China is not specified in the text, and payments are only broadly described as being handled by processors such as Stripe and PayPal. Before starting a trial, it is worth confirming network accessibility, available payment methods, and whether there are local alternatives, such as ShipStation, Shippo, Easyship, or simply using the built-in Shopify/Amazon backend tools.
