Project Overview: RoastSync – n8n D2C Coffee Subscription Batch Calculator & Courier Dispatch Engine
RoastSync is a production-floor and last-mile logistics automation pipeline built on n8n for Selem Specialty Coffee Roasters (selemcoffee.com).
The Business Challenge & Technical Requirements
Specialty coffee must be roasted to order and shipped the same day. Every morning, operations staff spent 3.5 hours exporting web orders and recurring subscriptions, grouping weights by bean origin (e.g., Ethiopia Yirgacheffe vs. Colombia Huila) and grind setting (Whole Bean, Espresso, V60), and manually typing shipping addresses into courier portals.

Technical Architecture & Full-Stack Implementation
Cynsera engineered a 6:00 AM scheduled n8n workflow paired with real-time checkout webhooks. n8n aggregates all due orders, calculates exact green-bean batch weights accounting for 14.5% roast moisture loss, sends formatted thermal batch tickets to the roastery printer, generates bulk Bosta and Aramex AWB shipping labels via API, sends WhatsApp roast-date tracking links to customers, and issues automated supplier PO drafts when green-bean inventory drops below threshold.
Key Outcomes & Measurable Impact
Saved 3.5 hours of daily manual operations, guaranteed 100% same-day roast-and-ship execution, and eliminated green-bean stockouts.
