Before you can create orders or begin despatching, your inventory must be added to the system. This is a crucial first step - once your products are in place, Helm can begin tracking stock levels, syncing with channels, and enabling fulfilment workflows

Getting Started with Inventory

In Helm, you can create orders manually whenever you need to record a sale outside of your connected channels, process a bespoke customer request, or add test orders for training. This process gives you full control over every detail of the order, from items and shipping to customer information and custom fields

On the Sales Channels page you can connect and configure every marketplace or storefront you sell through. Sync orders, manage stock mappings, and set channel‑specific rules to ensure all incoming sales flow seamlessly into Helm’s fulfilment workflows

Sales Channels - My Store

Sales Channels allow you to synchronise inventory, manage orders, and update stock levels across multiple marketplaces. Helm supports both OAuth-based and manual integrations. This guide is divided into three parts to help you configure your sales channels efficiently.

Setting up a Sales Channel

The Sales Channel Setups page provides a comprehensive catalogue of over 125 marketplaces and storefronts you can connect to Helm. Simply choose a channel, enter your API or integration credentials, configure order import and stock sync settings, and save. Once activated, Helm will automatically pull in orders, update inventory levels, and apply channel‑specific rules - streamlining multichannel operations from a single dashboard
