Systems that stop being the reason things go wrong

Reviews, integrations and due diligence for retailers whose stack grew faster than the plan for it.

What this is

Retail stacks are rarely designed. They accumulate, one supplier at a time, until nobody can say what a system costs or what would break if it were switched off.

The first job is usually not building anything. It is establishing what is actually there, what it costs and what it earns.

What follows is ordered by payback. The cheapest fix that removes the most pain goes first, regardless of how interesting it is.

Scale
200m+ Units a year processed on platforms I ran as IT Director at World of Books.
Growth
1% to 55% Share of £120m group turnover moved to the direct channel I built, from £100k to £4.7m a month.
Proof
£1.5m Turnover at Audio Trader within two years of founding, on a platform I built.

How it runs

If you need a full time engineering team, this is not that. It is one person establishing what should be built before you spend on building it.

  1. Step 01

    Map what exists

    Every system, what it costs, who depends on it and what happens when it fails. Usually the first document of its kind the business has had.

  2. Step 02

    Measure the real cost

    Licence fees are the easy part. The expensive part is the hours people spend working around a system, and that is the figure most businesses have never put a number on.

  3. Step 03

    Order by payback

    A roadmap sequenced by what it returns and when, not by what is newest. Anything without a clear payback is named as such and left out.

  4. Step 04

    Build against documented interfaces

    Integrations use real APIs with failure handling and alerting from the start. Nothing that depends on a screen layout staying the same.

  5. Step 05

    Leave it maintainable

    Handover notes written for whoever picks it up next, on the assumption that will not be me.

Audio Trader · music gear recommerce · Platform build and AI pricing

From zero to £1.5m turnover in two years on an AI pricing and operations platform we built ourselves

Secondhand gear only makes money if it is priced right at intake. I built Prism, the platform that values gear from live market prices in 15 seconds instead of 15 minutes, runs intake, inventory and listing, and sells across Shopify, eBay and Reverb from a single stock pool.

Result
£1.5m turnover in 2 years
