As answered by people managing EZStock and YieldStack.
EZStock's answer
I don't have consent to name customers publicly, but EZStock is in production use by Shopify stores managing several thousand SKUs and variants.
YieldStack's answer:
The largest CRE Lenders in the USA
EZStock's answer
Remix, Node.js, PostgreSQL with Prisma, and Shopify's App framework, including Theme App Extensions and Shopify Functions. Hosted on Railway. The app uses Shopify's Admin GraphQL API as the source of truth for inventory.
YieldStack's answer:
AI integrations supporting the platform’s workflows.
EZStock's answer
EZStock is built as a direct replacement for Shopify's Stocky, which is being discontinued. It ships a built-in importer that reads Stocky's own supplier and purchase-order exports, so you migrate in minutes instead of rebuilding by hand. Beyond that, it does the three things most inventory apps make you choose between: demand forecasting with days-of-stock-left, full purchase orders you can email to suppliers, and barcode stocktakes from a phone, all in one app at a small-business price.
YieldStack's answer:
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
EZStock's answer
Most Shopify inventory apps are either enterprise-priced or only do one piece of the job. EZStock covers forecasting, purchase orders, supplier management, and barcode counts together, starts free, and imports directly from Stocky so switching is painless. It syncs to Shopify as the single source of truth, so receiving a purchase order updates your live inventory automatically. If you want the Stocky workflow without the enterprise bill, that is the fit.
YieldStack's answer:
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
EZStock's answer
Small and mid-size Shopify merchants who have outgrown Shopify's built-in inventory tracking, especially stores coming off Stocky. Typically stores with real SKU counts and suppliers to reorder from, where stockouts and manual purchase orders have started costing time. Not enterprise warehouses, and not brand-new stores with a handful of products.
YieldStack's answer:
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
EZStock's answer
I build Shopify apps as a solo developer. EZStock started when Shopify announced Stocky was going away and merchants had no clear replacement that did forecasting, purchase orders, and stocktakes together without jumping to enterprise pricing. I built the Stocky importer first so people could actually move over, then grew it from there based on what real merchants asked for. One paying merchant with several thousand variants shaped a lot of the roadmap.
YieldStack's answer:
