Frequently asked questions.
Common questions about working with Exline Labs
How long does the typical project take?
It depends on what you're building. An MVP takes 1 to 6 weeks, and most of our recent ones went live in about a week. A web application takes 6 to 8 weeks. Your proposal confirms the timeline before any work starts.
Will I be kept in the loop about the project?
Yes. You get daily updates in your own channels, access to the project board and a demo at the end of every sprint. We're online 8am to 5pm UK time, so you can reach us during your working day.
How long are your contracts for ongoing work?
Ongoing work runs on a monthly retainer. Dedicated developer engagements start with a one-month trial. After that, either side can end the engagement with one month's notice.
Who will own the intellectual property?
You do. All our work is done on a work-for-hire basis, so the code, designs and documentation are yours, and everything transfers to you on completion. We sign an NDA before you share anything sensitive.
How do I start working with you?
Book a free discovery call, or send us a short brief through the contact page. There's no commitment. We research your project before we speak, and you get a fixed, milestone-based proposal within five working days of the call.
Where is Exline Labs based?
Our registered office is in Trincomalee, Sri Lanka. Most of the team works from Colombo, and a few work remotely from other parts of Sri Lanka. We're all online 8am to 5pm UK time, Monday to Friday.
How much does custom software development cost?
It depends on what you need, but here's where things start. An assessment of an AI-built or no-code app is from £750, and a UX audit from £800. Focused web apps, internal tools and web MVPs start from £5,000, and a focused mobile MVP from £10,000. A dedicated designer is from £2,200 a month, and a software engineer from £2,500. You get a fixed, milestone-based proposal before any work starts.
Can you take over an app built with AI or no-code tools?
Yes. We look at what you've built with tools like Lovable, Bolt or Bubble, fix what can be fixed and host it properly. We only rebuild the parts that need it.
Are you a software development company for startups only?
No. We're a custom software development company for startups and established SMEs. C4 Logistics, for example, has kept our team on a monthly retainer since we redesigned its platform.
Do you use AI to write code?
Yes, like most good engineering teams today. It's a big part of why our MVPs go live so quickly. Our engineers decide how the product is built and when it's ready to ship, and you own all of the code.
Where will my app be hosted?
If we host it, in the UK. The apps we host run on UK servers, with backups and monitoring, and we handle your data under UK GDPR. If you'd rather run it on your own AWS, Azure or other cloud account, we'll set it up and deploy it there.
How a project runs with us
How long does a typical project take from first conversation to launch?
It depends on the work. An MVP takes 1 to 6 weeks, and most of our recent ones went live in about a week. A web application takes 6 to 8 weeks, and a UX engineering engagement 8 to 10 weeks. Your proposal confirms the timeline as milestones before any work starts.
What happens after the product launches?
Many clients move to a dedicated developer or extended team on a monthly retainer. The same people stay on the product, so nobody needs re-briefing. We can also host the product for you on UK servers, with backups and monitoring.
How do I know what the team is working on day to day?
You get access to the Jira board from day one and can see every ticket. You also get a daily update in your own channel, and you join the sprint kickoffs and reviews where working software is demonstrated.
What if my requirements change during the build?
Changes are handled at sprint boundaries. We discuss them at the next kickoff, show you the effect on the timeline and budget, and nothing changes without your approval.
Do you sign NDAs and what IP rights do I own?
We sign NDAs before any sensitive discussion. All IP, including code, designs, assets and documentation, transfers to you on completion, and we keep no rights to it.
Where is my data hosted?
If we host your product, it runs on UK servers, with backups and monitoring, and we handle personal data under UK GDPR. If you'd rather run it on your own AWS, Azure or other cloud account, we'll set it up and deploy it there.
Do you work with clients outside the UK?
Yes. Most of our clients are in the UK, and we also work with clients in Germany, France, Ireland and New Zealand. Discovery calls are by video, and we're online 8am to 5pm UK time, with some flexibility for other time zones.
Fixing and launching AI-built and no-code apps
Do I have to rebuild my whole product?
Usually not. The assessment tells you whether a fix, a proper launch or a partial rebuild is enough. Most products we see need far less work than their founders expect.
What problems do you usually find in AI-built apps?
Most of the apps we review have at least one serious gap, such as exposed keys, open database rules or weak sign-in. They're usually quick to fix once someone looks properly, and the assessment shows you exactly where yours stands.
Can you take a Lovable app to production?
Yes. We review the code Lovable or Bolt generated, fix security and data handling, connect real payments and email, and deploy it properly. If it's a mobile app, we also take it through App Store and Google Play review. Most of these apps are a good base, not something to throw away.
Should I move from Bubble to custom code?
Only if Bubble is holding you back. If costs, speed or missing features are getting in the way, we move the parts that need it first, and your Bubble app keeps running while we do.
Can you host my app once it's fixed?
Yes. We host it on UK servers with automatic deployments, a staging copy, backups and monitoring, and we handle your data under UK GDPR. Hosting and care start from £300 a month. If you'd rather run it on your own AWS, Azure or other cloud account, we'll set it up and deploy it there.
What does it cost to fix an AI-built or no-code app?
The assessment is a fixed fee from £750, credited in full if you go ahead within 30 days. Fixing and launching starts from £1,500, a partial rebuild from £4,000 and a full rebuild from £15,000. You get a fixed price before any work starts.
Building your MVP
How do I know the minimum that will work?
We help you define the core problem first. Then we sort every feature into must-have, should-have, could-have and won't-have, and the first version gets the must-haves only.
What can you build in a week?
A focused MVP: one core user journey, sign-up and login, payments if you need them, and a live web app real users can try. We agree the scope in a day or two, and design and engineering work side by side from there. NoiseCase, our own noise logging app, went from idea to a working app in a week. Products with several user roles take 2 to 6 weeks.
Why do a phased build?
It's cheaper and less risky. You launch the core, learn from real users, and spend the rest of your budget on what they actually need.
Why do investors want to see an MVP?
It shows them a working solution, real demand and early feedback, rather than slides.
Do you integrate MVPs with third-party platforms?
Yes. We connect payment providers, CRMs, cloud storage and other services through their APIs.
Does it take long to do MVP development?
No. An MVP takes 1 to 6 weeks, depending on how complex it is, and most of our recent ones went live in about a week. Your proposal confirms the timeline before work starts.
What is MVP development?
MVP stands for minimum viable product. Minimum viable product development means building the smallest version of your product that real users can use, and ideally pay for, so you can test demand before you build the rest. Ours covers research, design, engineering and launch.
What technologies do you use for MVP software development?
Usually React, Next.js, Node.js and Python, chosen to fit your product. We add AI, APIs and automation where they help.
Can you help validate product-market fit during MVP development?
Yes. We start with market research and user interviews, then keep learning from real users after launch.
How is your MVP development approach different from others?
We research your idea before the first call, question the brief, and keep the same designer and developer from discovery to launch. You see working software as we go, not progress reports.
Do you offer support after launch?
Yes. We host your product on UK servers with backups and monitoring, fix bugs, keep things updated and help you scale, usually on a monthly retainer. If you'd rather run it on your own AWS, Azure or other cloud account, we'll set it up and deploy it there.
Do you use AI to write code?
Yes, like most good engineering teams today. It's a big part of why our MVPs go live so quickly. Our engineers decide how the product is built and when it's ready to ship, and you own all of the code.
Fixing and redesigning your product
What is user experience engineering?
It's UX design and front-end engineering done by one team. We find out why users struggle, redesign the flows, then build the fixes ourselves, so the design survives into the finished product. If you only need design, we offer user experience design services on their own too.
How much does a UX audit cost?
A focused audit of your main user journey starts from £800. Products with several user roles, platforms or a large number of screens are quoted after a short call. You get a fixed price before any work starts.
How long does a UX audit take?
About two weeks. We talk to your team, review the product against usability principles and go through it screen by screen. You get a ranked list of findings before you spend anything on a redesign.
What is a UX audit and what does it include?
It's a structured review of how usable and clear your product is. We look at the main user journeys, accessibility and the paths to conversion, and give you a prioritised list of what to fix. Our guide explains what a UX audit includes in more detail.
We already had a redesign. Why are the problems still there?
Because most redesigns change how a product looks, not how it works. If users are still confused, the cause is almost always in the information architecture, the user flows or the logic underneath. That's what an audit finds.
How does UX design increase conversions?
It removes friction, makes the next step obvious and guides people towards the action you want, whether that's signing up, booking a demo or buying. Small structural fixes often move conversion more than a full visual refresh.
What's the difference between UX and UI design?
UX is the whole journey a user takes through your product. UI is how each screen looks and behaves along the way. We do both. Read more about UX vs UI.
Do you work on products another team built?
Yes. Most of the products we work on weren't built by us. We review the existing design and front end before the discovery call, so we understand the constraints before we propose anything.
Do you build scalable design systems for startups?
Yes. We build reusable components with clear documentation, so your product stays consistent as it grows and new developers can pick it up quickly.
Can you design for both mobile and desktop?
Yes. Every design is built to work on small and large screens, and we test it on real devices before it ships.
Hiring dedicated developers
How does the one-month trial work?
After the discovery call, we match you with a developer or designer for your role, stack and seniority. They work with you for one month at the agreed monthly rate, in your hours, standups and channels. Tell us at least a week before the month ends whether you'd like to carry on. If you do, it continues month to month.
Can I hire one dedicated developer, or do I need a whole team?
Either. Most clients start with one developer or designer and add people as the product grows. Part-time is possible too, if you don't need someone every day.
How do you make sure they fit in with our in-house team?
They work 8am to 5pm UK time, join your standups and use your tools, such as Jira and Slack, from day one. We also match on how your team works, not just the tech stack.
Do you offer both front-end and back-end developers?
Yes, plus full-stack developers, UI/UX designers, QA engineers, DevOps engineers, AI engineers and project managers.
Which industries do you work with?
SaaS, healthcare, fintech, HR tech, sport, logistics and more, for clients across the UK, Germany, France, Ireland and New Zealand.
How much does a dedicated development team cost?
Full-time rates start at £2,200 a month for a designer and £2,500 for a software engineer. You get one monthly invoice and pay no recruitment fee. Use the estimator above to price your team.
What is the minimum commitment?
There's no minimum term. You start with a one-month trial, then stay month to month. Either side can end the engagement with one month's notice.
Do you offer a trial period?
Yes. Every engagement starts with a one-month trial at the agreed rate. Let us know at least a week before the trial ends whether you'd like to continue. After that, either side can end the engagement with one month's notice.
Who owns the IP?
You do. All work is done on a work-for-hire basis, and we sign an NDA before you share anything sensitive.
Do you work UK hours?
Yes. Our team is in Sri Lanka and is online 8am to 5pm UK time, Monday to Friday. Your developers join your standups and your Slack or Teams channels like anyone else on your team.
Can we scale the team up or down?
Yes. You can change the team size or the hours as your needs change, with one month's notice for a reduction.
Is this staff augmentation?
Yes. Staff augmentation, also called team augmentation, means adding outside developers to your own team, working under your direction. We look after hiring, HR and continuity, and you run the work. Read more in our guide to team and staff augmentation.
Is Exline Labs a software outsourcing company?
In a way, but unlike most outsource software development companies, you don't hand the work over and wait. Your developers join your team, work your hours and follow your roadmap, while we look after hiring, HR and continuity. It's closer to growing your own team than outsourcing a project.
Do your developers use AI tools?
Yes, like most good engineering teams today. It helps them get more done in a month. They decide what goes into your codebase, and everything they build is yours.
