This week the migration stopped being a solo project.
A three-module merge from a second developer lands clean behind a fail-closed production guardrail, quick reorder ships, and Monday’s pricing lesson pays rent within the week.

Build & migration log
Building it in public.
A running build log of a real ERP migration: half a million SKUs moving from a decades-old stack onto Odoo — the data work, the custom modules, the search layer, and the applied AI built along the way. Written as it happens, by the person responsible for it.
Entries
Best price wins.
Eight pricing tiers, ten quantity breaks per rule, and one absolute promise: the customer always gets the lowest price. Why the pricing engine became the migration’s clearest case for building custom.
read this entry →The most valuable thing we shipped this week was restraint.
The easy fix that lied, a statement feature parked rather than shipped with wrong numbers, a built-in read before it gets overridden, and why you diff every merge.
read this entry →Half a million SKUs, findable.
Carrying an Algolia-powered search experience across the migration when no connector existed: a friendly hostile takeover of the shop page, and a sync that grew from throwaway script to code-owned infrastructure.
read this entry →Trust, but read the network tab.
Evaluating a payment connector, DevTools showed raw card data hitting our own server. The vendor said sandbox-only. The source code said otherwise — so we walked.
read this entry →The store now knows what you’ve bought before.
This week: previously-purchased personalization ships across every shop surface, forty years of invoice history gives up its secrets, and three competing button systems become one.
read this entry →The enrichment machine.
An AI pipeline that researches and completes sparse product records — two models, a confidence gate, and humans only where judgment is genuinely needed.
read this entry →Half a million SKUs walk into a new database.
Moving decades of catalog out of legacy systems: importers, judgment calls, and the uncomfortable discovery waiting at the end.

A decade operating inherited systems, and the decision to replace them — where this migration came from and what the log will cover.
