How it works

Common questions.

01
No hours to count

Not an hourly arrangement. Quiet and busy months balance across the relationship.

02
Scope by deliverable

Defined by type of work, not time. Larger projects quoted separately.

03
Rolling monthly

30 days notice either way. No lock-ins, no contracts.

04
Small client list, by design

I work with a small number deliberately. That's how I stay genuinely useful.

Contact

Let's figure out
if we're a good fit.

I work with a small number of clients deliberately. Tell me what you're working on — I'll come back within 24 hours.

WHY NOT AN AGENCY

The person who
sells is the person
who builds.

Agencies sell you a team. What you get is a junior with a ticket. With me, the person you speak to in the scoping call is the person writing the Liquid, configuring the Flow, and reviewing the output.

AGENCY
Account manager → senior → junior → you wait
JACK NEVILLE
You → me → done
FIXED OVERHEAD
You pay for their office, staff costs, margin
NO OVERHEAD
You pay for the work. That's it.
KNOWLEDGE LOSS
Staff turnover means starting over
CONTINUITY
I know your store. No re-briefing.

“When you find someone so easy to work with, who gets what your needs are and delivers — that’s worth a lot.”
