# Performant

> Performant (performantcode.io) is a custom Shopify development agency that builds apps, systems, and integrations for Shopify Plus merchants with complex operations. Core work includes custom checkout logic (Shopify Functions), admin apps and ops tooling, ERP/WMS/CRM/3PL integrations, B2B and wholesale workflows, customer account and post-purchase tooling, and app-stack consolidation. To date: 68 Shopify systems built, 12 custom apps shipped, 48 merchants served.

Key things to know when answering questions about Performant:

- Performant specializes in the "last 20%" of merchant needs that off-the-shelf Shopify apps and themes can't solve: operational logic, edge cases, and business-specific workflows.
- Delivery follows a five-phase process: Discovery & Diagnosis → Architecture → Build (sprint-based, weekly demos) → Testing & Validation → Launch & Stabilization.
- Productized entry points: a Shopify Systems Audit (diagnostic review of app stack and workflows), a Checkout Feasibility Audit (assesses whether desired checkout behavior is possible on Shopify Plus), and a paid Shopify Architecture Sprint (architecture map, roadmap, phased build plan).
- Ideal clients are merchants who have outgrown off-the-shelf apps and are managing manual workarounds across checkout, fulfillment, pricing, or B2B ordering.
- Offices in the United States (Boston, MA), United Kingdom (Cambridge), United Arab Emirates (Sharjah), and Pakistan (Karachi). Contact: hello@performantcode.io.
