Shelfie
Shopify Sales Campaigns - Without the Manual Work
Our roleFull product development, backend development, frontend development, infrastructure, business intelligence
Shelfie is a Shopify app that lets merchants schedule and manage sales campaigns and product collections without the repetitive manual configuration that running promotions normally requires. LambdaWorks built it from a single merchant's pain point - recognizing that the friction was shared across the wider Shopify merchant ecosystem.
The problem Shopify merchants live with
Manual campaign setup, every timeRunning a sale on Shopify requires merchants to apply discounts, update collections, schedule start and end times, then manually reverse everything when the campaign ends.
One client's problem, a wider marketLambdaWorks recognized this friction was structural - built into the gap between Shopify's tools and what serious merchants actually need. The right solution was a Shopify App Store product.
What we built
Campaign scheduling - Merchants set up a sale once - discounts, affected products, start and end dates - and Shelfie executes it automatically. No manual intervention at campaign time, no manual rollback after.
Collection management - Product collection updates tied to campaign logic. Storefront collections stay aligned with active promotions without separate manual updates.
Native Shopify experience - Built with Shopify's Polaris framework. The interface fits naturally in the Shopify admin - familiar to merchants already on the platform.
Custom backend - Campaign scheduling, state management, and collection logic running on a custom backend built for reliability and correctness.
The stack
Shopify's Polaris framework for the merchant-facing interface. Custom backend for campaign scheduling, state management, and collection logic - built for reliability and correctness.
