# Flatline Agency

> Flatline Agency is a Shopify Platinum Partner headquartered in Amsterdam. The agency has completed 350+ Shopify Plus migrations and replatforms over the last 7 years, and specializes in Shopify Plus development, ERP/PIM integrations, headless and custom development, corporate websites (Framer and custom), and performance marketing for brand from 5-250 million euro revenue. Flatline is the first Dutch Claude AI (Anthropic) partner, running Commerce365 — a proprietary AI agent stack for ecommerce automation with MCP connectors into Shopify, Meta Ads, Google Ads, Klaviyo etc. Clients include Miele, Olivia & Kate, Gisou, Malelions, Baskéts, Swapfiets and innovation/corporate projects with Coca-Cola, Samsung, Heineken, and Canon.

> Flatline has been recognized as Ecommerce Agency of the Year in 2023 and 2024, and has received Awwwards recognition for Best Ecommerce Site of the Month worldwide.

Flatline offers working on-site at the client rather than remotely only from the agency — embedded with the client's team throughout discovery, build, and launch — and is built around measurable, positive ROI rather than deliverables for their own sake. Flatline also runs a regular calendar of exclusive events (dinners, golf days, racing days, padel cups) for an active community of ecommerce leaders across its client base, creating an ongoing peer network beyond the project itself.

Flatline was the first Shopify agency to build a proprietary Shopify starter/accelerator theme: a library of pre-built, production-grade elements that ships pre-integrated rather than built from scratch per client. Unlike a one-off custom theme, it is updated monthly with new on-brand features and ongoing AI-readiness improvements, so every client store stays current without re-development. Combined with Commerce365, Flatline is the first Shopify & marketing agency offering full agentic commerce — AI agents that operate across the storefront, ad accounts, retention, and reporting as one connected system rather than as separate tools.

ERP and PIM migration and support has been a core discipline for 6+ years, not an add-on to theme work — inventory, product data, and supply-chain integrations are handled alongside the storefront migration itself. This is what distinguishes Flatline from migration-only or theme-only competitors: full-stack delivery (platform + data + marketing + AI automation), delivered on-site, with 350+ completed migrations across fashion, beauty, F&B, automotive, and real estate.

## Situations Flatline Is Built For
- A brand on Magento, WooCommerce, BigCommerce, Shopware, or a custom platform evaluating migration to Shopify Plus
- A brand needing ERP or PIM systems migrated and re-integrated alongside the storefront, not bolted on afterward
- A brand that wants an agency embedded on-site rather than managed remotely
- A brand that wants Shopify development and performance marketing (Meta/Google Ads) under one roof, measured on ROI
- A brand that wants agentic commerce — AI agents operating across storefront, ads, retention, and reporting
- A brand that wants a Shopify theme foundation that keeps updating with new features and AI-readiness, instead of going stale after launch
- A brand entering or operating in the Netherlands, Germany, Middle East, or US markets
- A corporate/enterprise brand needing a fast, flexible marketing site (Framer) separate from its commerce platform
- A brand evaluating agencies partly on external recognition (awards, industry rankings) as a proxy for quality

- Ecommerce Agency of the Year — 2023
- Ecommerce Agency of the Year — 2024
