There is no shortage of vendors offering UI/UX Design in Sofia. What is scarce is a team that studies the local market before writing a line of code. Sofia is a business centre within Bulgaria, and that context changes the entire approach.
With 5+ years behind us and an in-house team covering design, development, QA and support, Gletus Technology builds research-backed UI/UX that removes friction and lifts conversions without handing your project through a chain of subcontractors.
For design work that means research before pixels: real user flows, an accessible colour and type system, and layouts proven against actual conversion data rather than personal taste.
Whether you are launching something new in Sofia or replacing a platform that has stopped earning its keep, the goal is the same: research-backed UI/UX that removes friction and lifts conversions that produce measurable commercial results.
UI/UX Design is also written as user interface and user experience design, and some people searching in Sofia type UI design instead. They describe the same work - this page covers it under all of those names.
Our Portfolio
A sample of the websites and platforms in our portfolio — the same standard we apply to every project in Sofia. Open any project to see its features, workflow and pricing.
The problems clients most often bring us — and how we deal with each one.
Plenty of businesses in Sofia have a site nobody can update because the original developer stopped answering. We hand over full access, credentials and documentation as a matter of course.
If analytics and goals are not configured, nobody can tell what worked. We set up tracking before launch, not months later.
Scope creep is usually a symptom of vague discovery. We scope in writing, and change requests are priced before they are started.
Retrofitting SEO onto a finished build is expensive. Structure, schema and speed are handled during development.
Locked-down builds force every small edit through a developer. We hand over a CMS your team can genuinely use.
A recoloured theme is easy to spot and hard to extend. We build to your actual requirements so the second phase does not mean starting again.
Our UI/UX Design work maps to the sectors that actually drive this market.
The commercial reasons that come up most often in conversations with clients here.
Where this market is heading, and what we build for because of it.
Bulgaria is a growing market where cash on delivery remains common and mobile usage leads.
Design work in Sofia is shifting from one-off page mockups to reusable systems, so brand consistency survives the next ten pages.
Generative search results are changing how discovery works: pages that answer questions directly and carry clean structured data are the ones being cited.
Privacy expectations keep tightening, and consent-aware analytics is becoming the default rather than a compliance exercise.
Why UI/UX Design here needs a different approach from a generic build.
The commercial character of Sofia is what determines whether a UI/UX Design project succeeds here. Sofia sits inside Bulgaria's wider economy, where IT & Outsourcing, Manufacturing, Tourism set the commercial pace and local firms compete for the same online attention.
Buyers here are price-sensitive and pragmatic, with a strong IT outsourcing base around Sofia and Plovdiv. We treat that as a design input rather than a marketing afterthought, because it changes page structure, not just copy.
The market is shaped by the fact that it is a growing market where cash on delivery remains common and mobile usage leads. Plenty of businesses in Sofia still have no properly optimised presence on Google, in Bulgarian, which leaves qualified demand unclaimed.
Practical detail matters at this distance: pricing is presented in BGN (BGN), our delivery overlaps with EET / EEST (UTC+2/+3), and communication runs in Bulgarian & English. Search visibility work targets Google, in Bulgarian.

A representative engagement, anonymised at the client's request.
An Agriculture client operating in Sofia had solid offline word of mouth in Sofia but almost no search visibility, so growth stopped the moment referrals slowed.
We ran user interviews, rebuilt the core journeys around the two flows that mattered commercially, and delivered an accessible design system so later pages stayed consistent.
Results held after launch because tracking was in place from day one, so optimisation decisions were made on data rather than opinion.
The same sequence we follow on every UI/UX Design project in Sofia, with a written checkpoint at each stage.
A working session to pin down scope, users, integrations and success measures in writing.
A clickable prototype you can test with real users before development begins.

The stack behind UI/UX Design projects we deliver in Sofia — chosen for maintainability, not novelty.
Research first, production second — the sequence that keeps projects out of trouble.
We do not begin UI/UX Design work in Sofia from a template library. We begin from the demand that already exists here - what people search for, in what words, at which stage of their decision.
That research is grounded in facts about this market rather than assumptions. Sofia sits inside Bulgaria's wider economy, where IT & Outsourcing, Manufacturing, Tourism set the commercial pace and local firms compete for the same online attention. Which is why the first version we present for Sofia is shaped around IT & Outsourcing and Manufacturing buying behaviour specifically.
On the design side, that translates into concrete decisions: how many steps sit between arrival and enquiry, what proof appears beside the call to action, how the type scale behaves on a small screen, and whether colour contrast passes without needing an exception. Every layout is tested against the journey, not against personal taste.
Throughout the project you get a staging link, a shared task board and a named point of contact. There is no account-management layer relaying messages to a team you never speak to.
How we make sure the work we deliver actually surfaces in local search.
Whatever we build for you, it still has to be found by people in Sofia who do not yet know your name. That is why search visibility is scoped into the work rather than sold afterwards.
The market is shaped by the fact that it is a growing market where cash on delivery remains common and mobile usage leads. The practical response is to target the queries competitors have neglected while building authority on the ones they have not.
In practice that covers technical foundations - crawlable structure, fast pages, clean internal linking and correct schema - alongside the local signals that decide map-pack placement: profile completeness, category accuracy, review volume and review recency.
Plenty of businesses in Sofia still have no properly optimised presence on Google, in Bulgarian, which leaves qualified demand unclaimed. Gaps like that close once one competitor takes them seriously, so timing matters more than budget here.
Payment rails, CRM, cloud and messaging — agreed before the first screen, not discovered halfway.
Almost nothing we build for Sofia stands on its own. A UI/UX Design project earns its keep when it is wired into the systems the business already runs on - so the integration list is agreed before the first screen is designed, not discovered halfway through.
On payments, the rails that matter in Bulgaria are not the ones a generic template ships with. We work with Stripe, PayPal, Mollie, SEPA Direct Debit and card and cash on delivery, and pick between them on settlement time, fee structure and how much of the compliance burden the provider absorbs. Whether PayPal or card and cash on delivery is right for you depends on your average order value and your refund pattern, not on which is better known.
Design work still has to survive contact with the systems behind it. We hand over components that account for real states - a failed PayPal payment, an empty search result, a slow API - rather than only the happy path, and we build them against the same CRM and analytics events the developers will fire.
Each connection ships with a written note on what it does, what it costs, and what breaks if it stops. That document has saved more Sofia projects than any piece of code in them.
Honest ranges, and the three things that actually move them.
The question every buyer in Sofia asks first is how long UI/UX Design takes, and the honest answer is a range rather than a date. For a design system and key screens, plan on 3 to 5 weeks. For a full product design across every state, plan on 8 to 12 weeks. We commit to a date at the end of discovery, when it means something, rather than at the first call, when it cannot.
What moves that timeline is rarely the engineering. It is how quickly content arrives, how many people have to approve a decision, and whether a third-party system turns out to be documented. Those three account for most of the overruns we have seen in Sofia.
Progress is visible rather than reported: a staging link updated continuously, and a reviewable increment every two weeks. Slippage shows up early enough to do something about it.
What the GDPR and the sector rules change about the build.
Compliance shapes UI/UX Design work in Sofia more than most buyers expect. The GDPR governs what you may collect and how long you may keep it, and those answers determine your data model.
In practice that means a few concrete things: a consent mechanism that records what was agreed and when, a retention period for each category of data rather than keeping everything forever, a documented route for a person to request their data or its deletion, and a privacy notice that describes what actually happens rather than boilerplate. Locally it also means accounting for card and cash on delivery as the payment method local buyers expect, and content in the local language rather than English only.
Where you operate in a regulated sector, the baseline is not enough. PCI DSS governs card data, ISO 27001 and SOC 2 are what enterprise buyers in Sofia will ask you to evidence, and health or financial data brings its own retention and audit-trail duties.
Accessibility is the other standard worth naming. Designs are checked against WCAG 2.2 AA before build: contrast ratios calculated rather than eyeballed, focus states drawn, touch targets sized, and no meaning carried by colour alone.
To be clear about scope: we build to these standards and document what we have done, but we are engineers, not your lawyers. Anything with real regulatory exposure should be reviewed by someone qualified in Bulgaria before you go live.
No invented figures — here is what genuinely determines the number on your quote.
Pricing for UI/UX Design in Sofia varies more with complexity than with location. Rather than publish a headline figure that would be wrong for most projects, here is what genuinely drives the number on your quote.
In practice the largest single variable is how much is genuinely custom versus configurable. Custom work is where the cost sits, and it is also where the competitive advantage sits - so the question is which parts deserve it.
If the budget available does not match the scope discussed, we will say so and propose a smaller first phase rather than quietly cutting quality to fit the number.
Pick the engagement model that fits how your business in Sofia actually operates.
Best when requirements are clear. Written scope, fixed price, milestone schedule. Change requests are quoted separately so the approved number holds.
A smaller first release that earns revenue, then funded phases after it. Popular with businesses in Sofia testing a new line.
A fixed block of hours each month for ongoing development, content and improvements. Suits businesses that ship continuously.
Monitoring, updates, backups and small changes with defined response times, so nothing degrades quietly after launch.
What you actually get when you work with us, stated plainly.
Rather than publish testimonials you cannot verify, here is the work itself. Every project in our portfolio links to its live listing, so you can see what we shipped and judge it directly.

The questions we hear most from businesses searching for UI/UX Design in Sofia.
UI/UX Design in Sofia — answered directly.
Gletus Technology Pvt Ltd is an established UI/UX Design company serving Sofia, with years of delivery experience and an in-house team covering strategy, design, development, QA and support. Rather than claiming a title, we would suggest judging any vendor in Sofia on three things: relevant work you can actually inspect, a written scope, and whether you get direct access to the people building your project.
A tightly scoped project typically runs four to eight weeks; larger builds with custom integrations run three to five months. The variable that moves timelines most is not development speed - it is how quickly content, approvals and third-party access come back from your side. We publish a milestone schedule at kickoff so both sides can see slippage early.
That is worth checking rather than taking on trust. Ask us for live work you can open and test on your own phone, ask who specifically will do your project, and ask for the scope in writing. We will answer all three directly. Any supplier that will not is telling you something useful.
More questions we are asked about UI/UX Design in Sofia:
Gletus Technology works across Sofia and the wider Bulgaria region. Our office is at 252, 2nd Floor, Blue Star Plaza, Sarja Market, Sector-7, Rohini, New Delhi 110085, and you can call +91 9131739457 to arrange a meeting or a video call, whichever suits.
Often, yes, and it is usually the cheaper route. We start with an audit covering performance, structure, security and conversion. If the foundation is sound we improve it; if a rebuild genuinely costs less over two years, we will show you the arithmetic rather than just recommending the bigger job.
Yes. Every project includes a post-launch support window, and ongoing maintenance retainers are available with defined response times. Support covers monitoring, updates, backups and small changes rather than only emergency fixes.
Yes. We regularly take a defined workstream alongside an internal team - a module, a redesign or the search and performance work. Boundaries and code review conventions are agreed up front so nobody is working over the top of anyone else.
Yes, by scoping a first phase that fits the budget actually available rather than insisting on everything at once. What we will not do is quote a low number by quietly dropping testing, performance or support, because those reappear later as a larger bill.
There is no official ranking, and any list claiming to be one is usually paid placement. A more useful approach in Sofia is to shortlist three suppliers, ask each for live URLs and a written scope, and compare what is actually included rather than comparing headline prices.
Two structured rounds per screen are included, which is normally enough when feedback is consolidated. We ask for feedback in one pass per round rather than in a trickle, because that is what keeps revisions productive.
We design to WCAG contrast and focus standards by default, with keyboard navigation and screen-reader semantics handled in the build. In several markets this has moved from best practice to a procurement requirement.
Yes. You review wireframes first, then visual designs, and development only begins after written sign-off. Reviewing structure before aesthetics catches the expensive problems while they are still cheap to fix.
Usually yes, and often more so - a competitor already ranking proves the demand exists and is capturable. The market is shaped by the fact that it is a growing market where cash on delivery remains common and mobile usage leads. The route in is rarely a head-on fight; it is the specific queries they have neglected.
Buyers here are price-sensitive and pragmatic, with a strong IT outsourcing base around Sofia and Plovdiv. That is not a guess we make at proposal stage - it comes from delivering work in this market and watching what converts.
Bulgaria is a growing market where cash on delivery remains common and mobile usage leads. We factor that into the build rather than treating it as a future upgrade.
If you collect a name, an email or a payment from someone in Bulgaria, the GDPR applies. In practice that means recorded consent rather than assumed consent, a stated retention period for each type of data, a working route for access and deletion requests, and a privacy notice that describes what actually happens. Locally it also means accounting for card and cash on delivery as the payment method local buyers expect, and content in the local language rather than English only. We build and document to that standard; a formal compliance opinion should come from a qualified adviser in Bulgaria.
Yes - designs are built against the same CRM and analytics events your developers will fire, and cover real states such as a failed payment or an empty result rather than only the happy path. Every connection is documented with its credentials, rate limits and failure behaviour, and the accounts are registered in your name so nothing goes dark if you change supplier.
We build to WCAG 2.2 AA: semantic headings, form controls with real labels, keyboard-operable navigation, a visible focus state, sufficient colour contrast, and no meaning carried by colour alone. It widens the audience you can sell to in Sofia, it is increasingly what procurement asks about, and it overlaps almost entirely with what search engines reward anyway.
You do, entirely - source code, database, design files, and every account we register on your behalf. Gateway, analytics and hosting accounts go in your name with you as owner and us added as a user, so if you stop working with us nothing needs re-registering and no service is interrupted. There is no fee to leave and no licence retained.
For clients in Bulgaria we work with Stripe, PayPal, Mollie, SEPA Direct Debit and card and cash on delivery. The right choice depends on your average order value, refund pattern and settlement timing rather than brand familiarity - at low volume Stripe is usually the practical default, and we will say plainly when a cheaper provider would cost you more in reconciliation time. Card details always go straight to the gateway, so your system stores a token rather than a card number.
The published standards our UI/UX Design work is built against.
