Real-time inventory sync that instantly stops overselling across Shopify, Amazon & Etsy
Solo ecommerce founders waste entire days manually syncing inventory across Shopify, Amazon, and Etsy, frequently causing overselling.
PulseSync connects to your channels via official APIs and webhooks, propagating every sale or update in under 3 seconds. When stock hits your buffer on one platform, it automatically pauses listings on the others. Solo founders get a single source of truth dashboard with zero manual CSV uploads or nightly batch jobs.
