How quickly can you start?

Discovery calls are usually available within 3 working days. Once the fixed quote is signed off, we typically start engineering within 2 weeks; sometimes faster if a slot opens. We will not promise a start date we cannot hold.

Who owns the source code?

You do, from day one. We commit directly to your Git host. There is no licence transfer at handover because the code was always yours. We retain no copies and we sign that into the engagement contract.

Why fixed quote and not hourly?

Hourly billing rewards slow engineers and punishes thorough discovery. Fixed quotes force us to scope properly up front, which is the cheapest way to build software. If we underestimate, we absorb the overrun. We have been doing this long enough that fixed quotes are accurate to within 10% the vast majority of the time.

What if scope changes mid-engagement?

We pause, rewrite the quote, and resume with your sign-off. Most engagements have one or two small change requests; we batch them at the next milestone to keep the workflow clean. Larger scope shifts become a separate engagement.

Yes, before any technical conversation. Our standard mutual NDA is one page; we will send it on request or sign yours.

Will the module work on Hyvä and Luma?

Yes. Every custom module ships with a Hyvä-first storefront layer and a Luma fallback. If you tell us at discovery that you are exclusively on one or the other we skip the unused layer.

What does PHPStan level 8 mean for me?

It means the static analyser catches type errors before code reaches your store. Stricter than Magento Marketplace Quality requires. Reduces the kind of subtle bug that surfaces three months after launch when a related module updates.

Can you publish the module on your marketplace?

Optional. If you want us to host distribution and run support escalation, we can list the module on the eTechFlow marketplace under your brand at 70% revenue share to you. You can also keep it private and only use it on your own stores.

Magento Custom Development

Bespoke Magento modules built by the engineers who publish their own. Fixed quote after a 30-minute call, code is yours.

Code quality: Reviewed before merge
Frontend: Hyvä-ready
IP: Yours from day one
Pricing: Fixed quote

Overview

What it is.

Custom Magento work from the engineers who publish their own production modules on this marketplace. Every engagement runs on a fixed quote after a 30-minute discovery call, payment tied to deliverables (not hours), and source code handed over before the final invoice. Every line of code is reviewed before merge. We tell you what we will build, what it will cost, and what we will not build. No surprise change requests.

What you get

Deliverables.

Module repository on your Git host (we never hold the source)
Composer-installable package with version pinning
PHPStan level 8 baseline clean from day one
Unit tests for the critical paths
Hyvä-first storefront layer with AlpineJS + Tailwind
Luma fallback layer for stores not yet on Hyvä
README with install + configuration walkthrough
CHANGELOG kept current through the engagement
Optional: marketplace listing on the eTechFlow store if you want us to host distribution

Honest limits

What it isn't.

We do not work on Magento 1; that platform is end-of-life
We do not subcontract or offshore engineering work
Hourly engagements only on existing retainer; new work is fixed-quote

How it works

From inquiry to handover.

01
1. Discovery (free)
30-minute call to walk through the problem and the constraints. We share a written brief at the end so we both agree on scope before any work starts.
02
2. Fixed quote
Written quote inside 3 working days. Deliverables, milestones, payment schedule, total price. Quote is valid for 30 days.
03
3. Build (variable)
Engineering happens in your Git repo with daily commits. You review every PR. Milestones billed on sign-off.
04
4. Review + handover
Final code review with you. Documentation walkthrough. Source code is already yours in your Git host; no further handover formalities.
05
5. 30-day stabilisation
Any bug surfaced inside 30 days of handover is fixed at no extra cost. After that, ad-hoc tickets or a retainer for ongoing work.
