Built by operators: Why we believe ERP had to change

Luminous connects to Shopify. GoodDay lives inside it.

While Luminous provides inventory tooling layered on top of ecommerce platforms, GoodDay is built natively into Shopify as a full Retail Operating System - uniting inventory, orders, and financial operations directly within Shopify, with real operator support from day one.

Why brands choose GoodDay over Luminous

Truly Shopify-Native

GoodDay runs directly within the Shopify Admin and uses Shopify’s native UI patterns, so teams work where they already are, without learning or maintaining a separate system.

Deeper inventory intelligence

Both platforms support inventory segmentation, but GoodDay goes further with things like, Automated FIFO COGS, Built-in Inventory reconciliation, and Finance-ready inventory data.

Built for scale, not just tracking

GoodDay is designed to support operational complexity as brands grow with things like multi-store setup and built-in WMS reconciliation that don’t exist in Luminous today.

Native integrations, less custom work

GoodDay has native integrations with category leaders like Loop, NuOrder, SPS, Crstl, and more. This allows brands to extend their stack without heavy custom integration or ongoing technical maintenance that brands choosing Luminous often experience.

Top-tier DTC brands trust us to run their ops seamlessly

GoodDay has been a game-changer for us. We finally have an ERP that actually fits the way modern brands operate — simple, flexible, and built for Shopify. It’s rare to find a partner who really gets both the brand and the business side, this team nailed it.

Before GoodDay, everything lived in Shopify, and pulling reports felt clunky and unreliable. We didn’t really trust the numbers...GoodDay is flexible and agile, but what really stood out was the team. They made the complex parts of our business feel simple.

Now [third party promo events are] as simple as a few clicks where we can just say, ‘we want to set aside these X,000 units, for a sale that's upcoming.’ We'll quarantine them now and then once the sales are completed, we can release them back into the pool. So that has saved a ton of confusion. Manual processes, and quite frankly errors.
