CUSTOM SOFTWARE DEVELOPMENT

Custom software development: portals, panels and integrations

We build software for the jobs an off-the-shelf package cannot do: dealer and customer portals, admin panels, quote and order flows, and connections that talk to the systems you already use. We also built Mars CMS, the content platform behind our client sites.

Mars Wear product page: a unit price that changes with quantity, an estimated total and a quote button
Mars Wear Qty → price Instant total and quote from the choice
When is it custom?
When your work does not fit a package, when several systems need to talk to each other, or when you want to give customers and dealers a screen of their own.
What do you build?
Dealer and customer portals, admin and reporting panels, quote and order flows, integrations and APIs.
How long does it take?
It depends on the scope. We launch larger projects in stages, starting with the part that will be used most.
Price?
We quote per project. The number of modules, user roles, integrations and languages set it.

OUR OWN SOFTWARE

Software of ours running every day

All of it is live; open it and try it yourself. We use the same foundations in client projects.

  • The quantity and price calculator on a Mars Wear product page: quantity options, unit price, estimated total

    Mars Wear · B2B catalogue

    Price by quantity, and a quote

    On the product page, choosing a quantity updates the unit price and the estimated total at once; the choice arrives ready in the quote form.

WHAT WE BUILD

Where a package falls short

Software that shortens the work of your team, your customers and your dealers. The most common requests:

  • Dealer and customer portals

    A screen where a signed-in dealer sees their own prices, orders and documents.

  • Admin and reporting panels

    A panel for managing records that opens by role and permission, with exports to Excel and reports.

  • Quote, order and application flows

    Multi-step forms, approval processes and notifications; every record is tracked in the panel.

  • Integrations

    Accounting, e-invoicing, marketplace, payment and ERP (Logo, Mikro, Netsis and the like) connections, built per project.

  • Web services and APIs

    Connection points so your systems can exchange data with each other safely.

  • Mobile app foundations

    The accounts, data and notification layer behind your mobile app.

WHICH BUILD?

Not every job needs custom software.

The right build is chosen for the job it has to do. All three routes have their place; we work out together in the discovery call which one fits you.

  • Website builder

    Drag and drop, monthly subscription

    When it is right
    Getting a brochure site of a few pages online quickly.
    Where it struggles
    When you need a flow, integration or design that the platform does not allow.
  • WordPress and plugins

    Ready-made themes, a wide world of plugins

    When it is right
    A content-heavy corporate site or blog with a standard structure.
    Where it struggles
    As the number of plugins grows, so does the burden of speed, security updates and compatibility between plugins.
  • Custom software

    A system built around your work

    When it is right
    Work with its own particular flow, integrations or multilingual scale.
    Where it struggles
    It takes discovery and design effort; the upfront cost is higher than off-the-shelf solutions.

SCOPE

What every project includes

Whatever we build, these layers of solid software are set up from the start.

  1. 01 / 06

    Discovery and information architecture

    We map who does which job in which order, and build the screens and data structure around it.

  2. 02 / 06

    Interface and experience design

    Screens designed for your brand that shorten the work of your team and customers.

  3. 03 / 06

    Role-based panel

    Who sees what and who changes what; a draft, approval and publish flow.

  4. 04 / 06

    Fast and secure foundations

    Pre-built fast pages, up-to-date security measures and regular backups.

  5. 05 / 06

    Multilingual structure

    A separate address for each language and content managed per language in the panel.

  6. 06 / 06

    Launch, monitoring and support

    Going live, error monitoring and technical support after handover.

PROCESS

From discovery to launch, stage by stage

We deliver large work in usable parts rather than all at once; you see each stage on a test address.

  1. 01

    Discovery

    We map the workflow, the users and the systems to connect, and write the scope of the first stage.

  2. 02

    Architecture & design

    We put the data structure, the screens and the technical architecture to you for approval.

  3. 03

    Development

    We build in stages and show each one on a test address.

  4. 04

    Testing & launch

    We go live after speed, security and workflow tests.

  5. 05

    Support

    After handover we provide technical support and plan new needs with you.

Step two of the Kampüse Hoş Geldin sign-up form: choosing the province, university, faculty and department

CLIENT WORK

Kampüse Hoş Geldin

We moved the site to Mars CMS while keeping its familiar design. The sign-up form was split into three steps; province, university, faculty and department are chosen from the official YÖK Atlas lists.

PRICE

Quote per project

With custom software, the work sets the price. After a discovery call we write the scope line by line and give you a firm quote.

WHAT SETS THE PRICE

  • 01 Number of modules and screens
  • 02 User roles and permissions
  • 03 Systems to connect
  • 04 Number of languages
  • 05 Hosting preference

WHO YOU WORK WITH

“We founded Mars Creative not as an agency, but as a partner that sits side by side with a small number of brands. We do not sell services — we offer care and the long view.”

We run projects remotely; in Istanbul, we can also meet in person.

FAQ

Questions about
custom software.

If your answer is not here, let’s talk it through in a short call.

Write to us →

How is the price of custom software set?

By the number of modules and screens, user roles, the systems to connect and the number of languages. After a discovery call we write the scope line by line and quote per project.

How long does custom software take?

It depends on the scope. On larger projects we launch the most-used part first and add the rest in stages; after discovery you get a written plan broken down by week.

When is custom software the right choice over a ready-made package?

When your workflow does not fit a package, when several systems need to talk to each other, or when you want to give customers and dealers a screen of their own. A brochure site of a few pages does not need custom software; a corporate site package is faster and cheaper.

Can it connect to our existing systems?

We build connections, per project, to systems that allow data exchange (ERP, CRM, accounting, e-invoicing, payments, marketplaces). In discovery we pin down which data flows which way, and how often.

Can we move away from WordPress?

Yes. We move the content into the new panel and redirect the old addresses Google knows to their new equivalents. We did this for Kampüse Hoş Geldin while keeping its design.

What happens after launch?

We provide technical support after handover, and plan security updates, backups and new development with you as needed.
