INTERNAL TOOLS & ECOMMERCE AUTOMATION
Custom Shopify Plus Internal Tools, Ecommerce Automation & App Development
Most Shopify Plus brands run 15–25 apps costing $2,000–$5,000/month — and still rely on manual processes for fulfilment, inventory and reporting. Conversion Design builds custom internal tools and ecommerce automation that replace bloated app stacks with purpose-built solutions.

(01) OVERVIEW
When does a Shopify Plus brand need custom internal tools?
You need custom Shopify Plus internal tools when your ecommerce operations have outgrown the limitations of standard apps. If your team spends 10+ hours a week on manual order processing, your 3PL inventory doesn't sync reliably, your CRM doesn't talk to Shopify, or your reporting requires exporting CSVs from 5 different platforms, you are losing revenue to operational friction.
We don't just build tools — we build tools that improve your Shopify store's conversion rate and operational efficiency simultaneously. Custom product recommendation engines increase AOV by 10–20%. Automated inventory sync prevents out-of-stock pages that kill conversion. Real-time reporting dashboards surface the data you need to make faster ecommerce CRO decisions.
Most DTC brands hit the custom tools tipping point between $500K and $2M in annual revenue, when app costs exceed $2,000/month and manual processes start costing more than automation. At that stage, custom Shopify Plus development typically pays for itself within 3–6 months.

How we build custom Shopify Plus internal tools
01
Operations audit and opportunity mapping
We audit your current Shopify Plus operations: app stack, manual processes, data flows, integrations and pain points. We map every automation opportunity and estimate the ROI of each, factoring in app cost savings, time savings, reduced errors and conversion impact. This produces a prioritised roadmap ranked by revenue impact.

This produces a prioritised roadmap ranked by revenue impact.
02
Solution architecture and scoping
We design the technical architecture: APIs, data flows, integration points and user interfaces. You get a detailed scope document with timeline, cost breakdown and expected outcomes before any development starts. We use Shopify Plus APIs, Shopify Flow, webhooks and custom middleware depending on complexity.
03
Development and integration
We build, test and integrate your custom tools with your existing Shopify Plus store and tech stack. Development follows an iterative process, so you see working features every 1–2 weeks rather than only at the end. Every integration is load-tested against your transaction volume.
04
Launch, monitoring and iteration
Tools go live with monitoring dashboards that track performance, errors and ROI metrics. We provide 2 weeks of post-launch support to catch edge cases. Ongoing maintenance and iteration is available from €500/month as part of our Shopify maintenance plans.
(05) PRICING

(07) TESTIMONIALS
What Shopify Plus brands say about our internal tools and automation
Rated 4.9 out of 5⭐ on Clutch across 200+ DTC and ecommerce brands.
““In my work with Conversion Design, I learned a lot about various dashboards, internal tools, and the importance of experimentation. Each session blended theory and hands-on learning, allowing me to test and implement strategies, then refine my approach after each review. Conversion Design’s feedback was effective, clear, detailed, and prompt.””
““Conversion Design rebuilt our Shopify Plus store from scratch — custom theme design, checkout flow optimisation, and ERP integration all handled in-house. What impressed us most was how tightly design and development worked together. The store launched on time, hits 96/100 on PageSpeed, and our checkout completion rate improved measurably in the first month.””
