Account management, or the first look at your store.
Ad hoc or a development retainer: your choice.
Ask for work as you need it, and everything requested in a month is itemised on one invoice at the end of it, each piece with its own price. Or agree a monthly development retainer and have a senior team working through your list every month. Larger pieces, such as a new build or an integration, are estimated in writing as a project. There is no account-management fee on any of them.

… Every time I’ve emailed them, they’ve been incredibly responsive with quick replies, clear answers, and genuinely helpful support. It’s rare to find a company that communicates this well. The quality of their work is second to none. Everything they’ve delivered has been polished, professional, and done to a very high standard. You can tell they really care about the end result and take pride in what they do. …

Questions merchants ask about this.
How do you price a piece of development work?
Each piece of work is priced as a whole, on what it takes: its complexity, the expertise it needs and how urgent it is. Small requests are simply done and itemised on your monthly invoice; for anything larger you get a written estimate first, from the engineer who will do the work. Our rate is £80 an hour plus VAT.
Who actually does the work?
Senior engineers who have worked on Magento for years, not juniors learning on your store. There is no account manager or project manager between you and them: you have one point of contact, who knows the work and answers your questions directly.
Can you work on a store that someone else built?
Yes, and most of our development work is on stores we did not build. We start with a read-only look at the code, the hosting and the patch state, so that we understand what we are changing before we change it. Where the existing code makes a task harder than it should be, we say so and explain the options.
Do you build custom modules or install extensions?
Whichever is right for the task, and we tell you which and why. A well-maintained extension from a vendor who will support it through the next release is often the better answer. Where nothing fits, we write a module to Magento's coding standards, with the source in your repository.
Which integrations have you built?
Payment providers, cross-border selling, order management and ERP systems, email marketing, address lookup and site search, among them Mollie, Global-e, Orderwise, Klaviyo, Loqate and Klevu, and Microsoft Dynamics 365 Business Central with our partner n.vision. If your system has an API, the question is how it should connect rather than whether it can.
Is Hyvä development the same thing?
It overlaps. Backend features, integrations and fixes are the same work whichever frontend you use. Theme and frontend work on Hyvä has its own page under Hyvä development, because the toolset is different and we are a Hyvä Silver Partner.
Do you build Magento stores from scratch?
Yes. New stores are built on the current supported release with a Hyvä storefront, designed around your brand and your catalogue. Start-ups with small budgets and established retailers both begin the same way: a conversation, then a written plan and estimate.
Can we hire a Magento developer from you for a set period?
In effect, yes. A monthly development retainer gives you a senior team working through your list every month, without recruiting, managing or covering holidays. It can be increased, reduced or paused as the list changes.
Do you work for other agencies?
Yes. We work alongside design, marketing and other development agencies, under our own name or white-labelled under yours, on single tasks or whole projects.
