Commonly Asked Questions

Development is a dynamic process, and things can take longer than expected.

We limit our availability to take on new projects so we can deliver revisions and progress updates for ongoing projects within 48 hours.

By limiting the number of active clients, we can prevent slow-downs and ensure everyone gets the attention they need.
We offer monthly slots at £2,995 each.

For longer projects or to save on future costs, we have a 3-month option for £7,485, which comes out to £2,495 per month.

With any subscription, you can queue up as many requests or jobs as you want, and we’ll tackle them in order.

You’ll get progress reports every 24-48 hours.

Pricing details
We’ve ditched per-hour billing for two big reasons.

First, different projects have their own ways of counting active hours, which is a headache for us and confusing for you.

Second, per-hour billing feels too restrictive. With our subscription model, you can aim higher with your development goals.
Plus, by pre-paying, you stay in control of your budget and never have to worry about overspending.
Absolutely!

If you need alternative timeframes for your development project, just let us know.

We understand that schedules can be tight or change unexpectedly, so we’ll do our best to accommodate your needs.
Whether you need to speed things up or take a bit more time, we’re flexible and can adjust our timelines to fit your situation.

Just reach out and we’ll figure it out together.
We can give you an estimate once we get the details of your project.

We dislike overspending just as much as you do, so we keep our estimates upfront and realistic to make sure you always feel in control of your budget.

Plus, you can pause anytime and save up to half your unused time for later.
We're happy to join your team.

Just keep in mind that our availability and responsiveness might not always match up perfectly with your team’s schedule.

We’ll do our best to stay in sync and support your project.
Our team consists two permanent members; a Developer and a Designer.

Our Developer handles all the technical aspects, while our Designer focuses on making everything look great.

We’re a small but dedicated duo, dedicated to delivering high-quality work.
