What It Is

iSync is an operations automation SaaS for brands using Amazon Vendor Central. Its core goal is to automatically handle Purchase Orders, calculate true SKU-level gross margin, control inventory, and plan manufacturing, reducing the time spent manually processing orders and logistics documents. The site emphasizes that it is built from hands-on Amazon Vendor Central experience, and also provides documentation, templates, and troubleshooting guides.

Core Features and Integrations

The product is designed around the Vendor Central purchase order workflow. After a PO is imported, the system can validate MOQ, inventory, and target gross margin line by line, then recommend whether to accept or reject each item. Gross margin calculations support 7 categories of cost components, including manufacturing, logistics, picking, advertising, commissions, finance, and other costs. iSync can also generate Amazon-compliant ASN, labels, and logistics documents, while forecasting stockouts based on supplier lead time and planning manufacturing schedules for 30-60 days of coverage.

On the integration side, Amazon Vendor Central is currently handled mainly through Excel imports. Holded ERP can sync inventory and products via API, and generate sales orders after orders are accepted. Amazon Ads is used to import advertising costs and calculate true ACoS/ROAS. OneDrive can automatically sync Excel files. Microsoft Teams sends alerts via Webhook for inventory, gross margin, import failures, and manufacturing plans.

Pricing, Collaboration, and Security

The site provides a “free registration” entry point, but does not disclose plans, pricing, trial duration, feature limits, or payment methods. For team collaboration, the documentation mentions that users can be invited and assigned Admin, Operations, or Finance roles, making it suitable for joint use by operations and finance teams. However, it does not explain granular permissions, approval workflows, or audit logs. Security and compliance information is relatively limited: only technical Cookie information is visible, along with documentation entries related to security controls and SP-API/PII, but there is no disclosure of certifications, encryption, data residency, or SLA.

Pros, Cons, and Who It’s For

Its main strength is its highly focused use case: it connects PO processing, inventory, gross margin, advertising costs, and ASN documentation in one workflow, making it especially suitable for brands with high Amazon Vendor Central order volume that need to avoid low-margin orders. The documentation also provides Excel templates and common error handling, lowering the difficulty of initial setup. The limitations are that pricing is not transparent, Vendor Central is not fully connected via API, and its value will drop significantly for teams that are not Amazon Vendors or do not use Holded.

Access from China and Alternatives

The site does not provide information about access from mainland China, network nodes, or RMB payment, so its China access status is unknown. Domestic teams should test access speed, login, the availability of external services such as OneDrive/Teams/Holded, and payment methods in practice. Possible alternatives include 聚水潭, 旺店通, 马帮 ERP, 店小秘, and other ecommerce/cross-border ERP products, but whether these tools cover Amazon Vendor Central workflows such as PO, ASN, and gross margin validation needs to be verified step by step against the actual process.
