Custom software

Custom software development agency

Off-the-shelf software stops at your actual process. We are a custom software development agency: MVPs, client portals, internal tools, and AI features that sit inside a real product — built by a studio in Sarajevo that works in English with US and European teams. This is systems work, not a marketing homepage and not a single-platform mobile sprint.

The SaaS you already pay for will not become your process

Off-the-shelf tools stop at the edge of how you actually work. A rent-a-car calendar is not a generic booking widget. A portal your clients log into is not a shared Drive folder. Custom software development at CodeLoop Studio is that slice: MVPs, internal tools, client portals, and AI features that sit inside a product people already use — not a chatbot taped onto a broken workflow.

The studio is in Sarajevo. Clients are typically in the US, Germany, and the wider EU. Communication is English. Hours overlap CET and, when needed, Eastern mornings. Hire a pod or a single senior engineer; either way the studio is accountable. You keep repositories, cloud, and domain. A vanished-vendor lock-in is a failure of the engagement model.

If you only need App Store chrome, custom mobile app development is the tighter brief. If you only need a site that ranks, use website development. Stay here when the system behind the screens is the work. A scoped reply lands within 24 hours of a usable brief via the online estimate.

Integrations, AI jobs, and an owner after the demo

We build the slice of software your SaaS stack refuses: booking with fleet rules, portals your clients log into, admin that matches how the floor actually works, MVPs that investors can tap. Delivery includes QA, a stack you can live with, and an owner who is still there after the demo. Hire a pod or a single senior engineer; either way the studio is accountable. Integrations — payments, identity, CRMs — wire what you already pay for instead of inventing a fourth database. AI features when there is a job: search, classification, drafting, routing, inside a product people already use. We will not bolt a chatbot onto a broken workflow and call it a transformation.

Clients are typically in the US, Germany, and the wider EU. Communication is English. Hours overlap CET and, when needed, Eastern mornings. You keep repositories, cloud, store, and domain. We work inside your orgs. Typical product work lands in the three-to-nine-month band; a ruthless MVP can be shorter. Weekly demos and written status you can forward internally. After launch we can run the backlog or hand over with documentation.

Hena Em is a rent-a-car system: public booking plus fleet admin, reservation calendar, availability for cars and vans, gallery, automated email. Rules, calendar, and operations — not a brochure with a form. If you only need App Store chrome, custom mobile is the tighter brief. If you only need a site that ranks, use website development. Berlin teams have a CET city page. Stay here when the system behind the screens is the work.

What custom software actually includes here

A vertical slice users can touch

Rules the SaaS refused

Fleet availability, shift admin, pricing that is not a spreadsheet. The process is the product.

Integrations you already pay for

Payments, identity, CRMs. We wire what exists instead of inventing a fourth database.

AI when there is a job

Search, classification, drafting, routing — inside software people already use. Not a transformation slide.

QA and an owner after the demo

Written status you can forward. After launch we can run the backlog or hand over with documentation.

Berlin hours, Sarajevo studio

Same CET band as DACH teams. The honest city page for that market is a custom software agency for Berlin.

How a custom software engagement runs

01
Process before stack
Who uses it, what “done” means, which systems you already pay for. Stack is a recommendation after that, not a religion on the first call.
02
Freeze v1 in writing
Roles, the report a director will open, what waits for v1.1. An MVP that secretly includes every investor slide is a full product with worse planning.
03
Ship a thin slice
Something a user can finish. Then the next slice. Typical product work lands in the 3–9 month band; a ruthless MVP can be shorter.
04
Weekly demos, written status
You can forward the update internally. Silence until a big-bang launch is how software projects die.
05
Handover or stay
You own the code. We can remain on the backlog. Either way the accounts stay in your orgs.

Staff a seat, or own a product

Dedicated engineer

One senior in your repo, your process, your tools. The studio still owns quality. Fits when you already have a product team and a backlog.

Product squad

Discovery, design, build, QA. We freeze the slice and ship it. Fits when the system is the work and you need delivery ownership, not a body shop.

Frequently asked

Both, on purpose. Some clients need a feature factory with a PM. Some need one engineer in their repo. We say which model fits before we staff.

Yes, when there is a job for them — search, classification, drafting, routing — inside a product people already use. We will not bolt a chatbot onto a broken workflow and call it a transformation.

You do. Repositories, cloud, store, and domain stay in your orgs. We work inside them. A vanished-vendor lock-in is a failure of the engagement model.

Use the online estimate. We aim to respond within 24 hours with next steps, and a scoped number after we have seen enough of the process to avoid fiction.
