Built by operators: Why we believe ERP had to change

Beyond spreadsheets. Built to scale.

Spreadsheets break down as inventory complexity grows—manual updates, version conflicts, and delayed data make them unreliable at scale. GoodDay replaces spreadsheets with a real-time Retail Operating System, purpose-built to manage inventory, orders, and financial data with accuracy and automation.

Why brands move on from spreadsheets

Spreadsheets don’t scale

Manual updates, fragile formulas, and version-control issues introduce risk as order volume, SKUs, and sales channels grow. What works early quickly becomes a liability.

Cleaner data, better decisions

GoodDay eliminates duplicate entry and keeps data automatically in sync across Shopify, warehouses, and financial systems. The result is a single, reliable source of truth that teams can trust when making decisions.

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.
