75 minutes. One issue. Screen-share. Fix it live or leave with a clear plan.
One session. One issue (or few smaller ones). We'll scope it out, and then I'll fix each issue live, right in front of you. If it's bigger than the session, you leave with a clear plan and priorities — not a sales pitch.
$199 AUD / 75 mins (online screen-share)

I take Australian Shopify brands with global ambitions, make their sites blisteringly fast while obliterating glitches & bugs, all for a fraction of the cost (and none of the hassle) of a big budget agency. You'd be surprised how much can be done in just a few hours a month, so why not give it a try?








Most Shopify stores don’t need a “project”, or a big ass quote for a custom theme. They need one thing fixed: a broken add-to-cart, a slow product page, app bloat, or a manual process that’s turned into a tax.
This is paid problem-solving. We’ll focus on one issue at a time, fix what’s safe during the session, and you leave with a short, prioritised plan either way.
No retainers. No proposals unless you ask.
75 minutes. One issue. Screen-share. Fix it live or leave with a clear plan.
You’ll get written priorities within 24 hours: do this / don’t do this / later.
My no. 1 goal is to make you a smiling happy camper who is 100% satisfied.
I've worked with many Shopify developers over the years and John is a serious operator. His services are fast, affordable, and the quality of the work is top-notch.

Got questions? We've got answers.
We pick one primary symptom (e.g. add-to-cart flaky on mobile, PDP slow, app conflicts, variant UX). We reproduce it, isolate the likely cause (theme vs app vs settings), and fix what’s safe within the session. If it’s bigger than the session, you still leave with a short, prioritised plan and the exact next steps.
No. You’re paying for the session. That’s the transaction. If bigger work is uncovered, you’ll get options: - DIY with the plan - Book another session - Or ask me for a fixed-scope quote No proposal unless you request it.
Only with your permission, and only if it’s safe. Default approach is: - You give JohnDetlefs.com collaborator access (I'll walk you through it) - We'll duplicate the theme (so we don't break what's already there) - I'll create a local instance and screenshare what we're doing - You preview the changes and approve (or we'll iterate) - Then we push the changes to your store Anything risky (checkout, payments, live discount logic) gets handled conservatively with rollback in mind. If you don't have a Github account set up yet, we can set that up for you -- makes rollbacks easy!
Best case is Shopify collaborator access (limited to what’s necessary) so we’re not guessing. If you’re not comfortable, we can do screen-share only — it just reduces what we can fix live. I don’t need access to payments, bank accounts, or anything unrelated. You can revoke access immediately after the session.
That’s common for messy problems. You still get value: - What we’ve ruled out - What the most likely causes are - The fastest path to confirm the root cause - A prioritised action plan (small/medium/big effort) within 24 hours If you want me to implement, we’ll only quote a small fixed block once the scope is clear.
Because it filters tyre-kickers and pays for real prep and follow-up. You’re buying a focused troubleshooting session, not a sales meeting.
Projects start at $40k, and I only take on a couple a year, so I recommend booking a call to discuss your needs and timelines. If it’s not a fit, no worries — you can still get a ton of value from the Fix-It Call.
That said, if we do go ahead, I'll comp the cost of your Fix-It Call towards the project, so it’s a win-win either way.
Note: These days I'm not really open to managing an offshore team or doing project management... AI has changed the game so much that I can get more done in less time by just doing it myself! So you kind of get the best of both worlds -- the expertise and execution of a senior dev, combined with the cost saving benefits of an "augmented developer" model.
