Our method
01
Discover
We believe the solutions of the future can’t always build on past experience. It takes courage to break free from recreating what already exists, and instead create what comes next.
02
Design
Beautiful apps and websites are not enough. Proto-personas and use cases are only the first step towards understanding your audience and fulfilling their needs.
03
Develop
Choosing the right technology for each individual project is our bible. Doing something just because it falls within our comfort zone has never been a good approach.
04
Deploy
Measuring impact is a never-ending process that starts after launch. Small changes make big impacts through iterations that show exactly what works for your audience.
40–60%
Lower project cost than comparable Western European agencies, for the same senior engineering.

What clients say
With Presta, you can trust that the work is going to be elevated to a new level. I’ve worked with them on several projects at Audi where their unique perspective and creative approach was instrumental in defining our product vision and direction.

FAQ
Questions clients ask before we start
How much does a project cost?
Most projects are fixed-price, agreed before work starts. Shopify stores start from €5,000, and stores with integrations, B2B pricing or several languages typically run €8,000–15,000. Shopify migrations typically cost €5,000–10,000. Custom web applications start with a Discovery Workshop from €2,500, credited to the build, and MVPs typically cost €5,000–10,000. Every quote lists exactly what is included, so the scope and the price stay fixed.
Which service do I need?
If you sell online, start with a Free Store Audit or a 30-minute call. If you are building a product or the scope is unclear, start with a Discovery Workshop. We will point you to the right service, even if it is not ours.
Do you work with clients outside Serbia?
Yes. Most of our clients are in the EU, the UK and the US, with others in Australia and Asia. We work in English and Serbian, in Central European Time, with overlap into US mornings.
Are your prices fixed?
Projects are fixed-price per phase, agreed before work starts. Only retainers are hourly, and you are billed only for the hours used.
Is Presta a Shopify Partner?
Yes. Presta is a Shopify Partner based in Belgrade and has built and migrated more than 25 Shopify stores since 2014.
Who will actually work on my project?
The same senior designers and engineers you meet in discovery. You talk to the people building your project, not to an account manager.
