No-code rules engine for perfect inventory control across all your stores
Solo ecommerce founders waste entire days manually syncing inventory across Shopify, Amazon, and Etsy, frequently causing overselling.
RuleStock provides a visual rule builder so you can define exactly how you want inventory to behave (e.g. 'If Etsy sells 5 units, reduce Amazon by 8 and notify me'). Rules run on every sale via webhooks. The system learns common patterns and suggests new rules based on your behavior.
