What a month actually contains

Every retainer begins with an audit, so month one has a roadmap, not guesses.

  • Two or three conversion changes or tests shipped, chosen from a prioritised backlog.
  • The development hours to build them properly.
  • One AI module where it pays: support automation, catalogue and content operations, or experimentation tooling.
  • A one-page report: what shipped, what it did to conversion, AOV and revenue, what's next.
  • Replies within one working day, always.

Why not just apps?

Apps are how most stores got slow. A retainer removes before it adds, tests before it trusts, and builds only what the numbers ask for.

Questions about the retainer

Why a three-month minimum?
Month one is roadmap and quick wins; the compounding starts after. Then it's 30 days' notice, no lock-in.
What's an AI module?
A working automation in your store's operations: support triage, catalogue and content generation with review, or test build-outs. One at a time, only where it pays back.
What if we need more development hours?
Bigger pieces get scoped as fixed-price sprints alongside the retainer, quoted before they're built.
Do you replace our developer or agency?
No. Our lane is conversion. We work alongside paid, email and in-house teams.
