The Subscription account enables you to post more frequently (daily), while the Service account only allows you to post four times a month. However, notifications for any updates on Service accounts will appear directly in a user’s conversation log, while the posts from a Subscription account are limited in a subscription folder without any visible notifications on WeChat’s main operation panel.
Furthermore, many of WeChat’s unique features, such as CRM and custom menus, are only available to Service accounts.
In general, if your product offering is content-centred (e.g. media, key opinion leaders (KOLs), newspapers and magazines etc.), you should go for the Subscription account. In other cases, especially when you run an e-commerce business, we would suggest that you go for a Service account.
