ERP Integration: The Conversation Your E-Commerce Project Can't Avoid

Mid-market businesses run on their ERP, so any e-commerce platform that doesn't talk to it properly is a toy. Here's why ERP integration is harder than anyone admits, and the CSV process we built in 2006 that's survived three ERP migrations.

The Iceberg: Where €200k Actually Goes on a Mid-Market E-Commerce Build

The storefront is maybe 30% of a mid-market e-commerce project. The rest sits underwater: integrations, data migration, business logic. Here's where €200k actually goes, line by line, and why a cheap quote is usually a deferred invoice.

The €200k Sweet Spot: My Codegarden 2026 Talk on Mid-Market E-Commerce

Last week at Codegarden I argued that the most underserved part of e-commerce is the €150-300k middle: too complex for Shopify, too sensible for enterprise. Here are the slides, the argument, and what's coming next.

What a slow Chrome trace told us about a 2,000-product catalogue page

Running Products Alongside Client Work: Why It Took Us 15 Years to Get This Right

After 15 years building products at TSD, we're only now structuring this properly. Running an agency and running a product need different mindsets. Project completion vs continuous iteration. Clear deliverables vs never being "done". Here's what we learned the hard way.

A Cautionary Tale on Platform Dependency: Why Our Shopify App Went From Daily Installs to Zero Overnight

Platform products give you faster time to market and built-in distribution. They also give you existential risk. When Reddit changed API pricing, Apollo went from multi-million pound business to dead overnight. Here's what happened when our Shopify app installs stopped, and how we manage risk now.

From Napkin Sketch to App: How We Validate Product Ideas

How do you decide what products to build? We assume everything takes three times longer than estimated and markets are three times smaller than we think. Sounds pessimistic. Turns out to be fairly accurate. Here's the validation framework we use at TSD to avoid wasting months on ideas nobody wants.
