Pars Design

SaaS and
Business software.

We design and develop portals, SaaS and internal business software, bringing user experience, technical architecture and development together. Where useful, we integrate AI to solve a real product problem.

What this service addresses.

Business software becomes complex when roles, permissions, data and exceptions meet in one system. Good product design turns that complexity into clear decisions for the user.

Product scope, user flows, the interface system and technical architecture share one roadmap, helping your team progress from a working MVP to a product that grows in manageable steps.

Who it is for.

  • Startups developing a new SaaS product or MVP
  • Organisations building a customer or dealer portal
  • Companies bringing internal processes into software
  • Product teams updating or taking over legacy business software

Scope.

The work below is scoped to your needs. Deliverables and responsibilities are agreed in the proposal.

  • Product discovery and MVP scope
  • Roles, permissions and user flows
  • Dashboards and management interfaces
  • Multi-tenant product architecture
  • APIs and third-party integrations
  • Releases, monitoring and maintenance

Deliverables.

Source files, access, third-party licences and ongoing support responsibilities follow the agreed scope. For projects using AI, deliverables may include:

  • DELIVERABLEAI feature prototype
  • DELIVERABLESystem & integration architecture
  • DELIVERABLEPrompts and behaviour guidelines
  • DELIVERABLEData sources and access structure
  • DELIVERABLEHuman approval and error scenarios
  • DELIVERABLEManagement and monitoring screens
  • DELIVERABLETechnical documentation
  • DELIVERABLESource code and developer handover

What we do

Product discovery and MVP scope

A documented first-release scope, narrowed through three questions to establish what is included and what comes later.

Management dashboards

Data-rich screens, filters and bulk actions for interfaces people use for hours every day.

Multi-tenant architecture

Separate customer data on shared infrastructure, with roles, permissions and tenant settings established from the start.

Subscriptions & billing

Plans, trials, payment infrastructure and billing flows, with the foundations in the first release.

APIs & integrations

Documented APIs and common integrations so customers can connect their own systems.

Scaling and maintenance

Infrastructure, monitoring and backups as usage grows, supported by monthly maintenance.

AI-enabled development

We add AI where the product needs it.

We first assess user needs, business processes and available data. Where there is a clear benefit, we integrate AI search, content generation, classification, recommendations, automation or assistants into existing product flows.

We consider the whole system, from model and service selection to interface behaviour, data access and human approval. The goal is software that is controllable, maintainable and suited to everyday use.

AI product features

We add search, summarisation, classification, recommendations, content generation and decision support to existing product flows.

Company knowledge & RAG systems

We build knowledge retrieval experiences that work with documents, content and internal data, and can show their sources.

Agents and workflow automation

We design task-focused agents that handle recurring work, connect to the required systems and ask for user approval at critical steps.

API and system integrations

We integrate AI services with CRM, ERP, content management, support, commerce and internal software, with appropriate controls.

Conversational interfaces

We develop assistants for web, mobile and messaging channels, grounded in the product’s content and business rules.

Control, security and monitoring

We include permissions, data boundaries, human approval, error handling, logs and usage monitoring in the product design from the outset.

Six steps from idea to launch.

Each step has a concrete deliverable, so you know what to expect and when.

01

Listening

"tenant separation?"“onboarding takes too long”"confusing permissions"

We map the business model, user roles and competitors.

→ role map, scope document

02

Architecture & planning

We design tenant structure, permissions and main flows.

→ data model, flow diagrams

03

Prototype

We test the clickable prototype with pilot customers.

→ tested prototype

04

Build

We progress design and code in two-week releases.

→ working builds, component library

05

Launch

livev1.0

We onboard the first customers with monitoring and measurement in place.

→ live environment, analytics dashboard

06

Growth

v1.2v1.1

We update the roadmap using real usage data.

→ release plan, monthly report

When AI is needed, these steps also include:

  1. 01Assessing whether the problem calls for AI
  2. 02Reviewing available data and knowledge sources
  3. 03Choosing a suitable model, service or architecture
  4. 04A focused validation exercise or prototype
  5. 05Designing the interface and user control points
  6. 06Integration, testing, monitoring and improvement

How we work.

Timing, team and deliverables: what to know before our first conversation.

Timing
First release in 10–16 weeks
Working arrangement
A fixed scope for the first release, followed by a monthly product team arrangement.
Team
Product manager, two designers and three developers
The first two weeks
Role map, draft data model and first-release scope.
What you keep
Source code, database, cloud accounts and design files.

Tools we use

Development

  • Next.js
  • TypeScript
  • Supabase
  • PostgreSQL

Payments

  • Stripe
  • iyzico

Measurement

  • PostHog

In focus: Mahalle Intranet.

The situation
Branch and head-office teams used different channels for announcements, training and requests. Reaching hundreds of branches at once was difficult.
What we did
We built an internal platform for branch, regional and head-office roles, with an announcement feed, training content, request management and branch-level permissions.
The result
  • A shared workspace for branch, regional and head-office teams
  • One place for announcements, training and requests
  • A content feed tailored to roles and permissions

Frequently asked questions

Can you develop just an MVP?

Yes. We can start with an MVP focused on the essential user value and business assumption. Architecture and design decisions allow later releases to be added without unnecessary rebuilding.

Can you take over existing software?

Yes. We first review the code, infrastructure, design system and unresolved issues. If a handover is viable, we plan the transition. Critical risks and options are discussed before proceeding.

Are billing and membership systems included?

Membership, plans, payment and billing flows can be included. Providers, countries and regulatory requirements are clarified before technical design.

How does technical maintenance work?

Monitoring, bug fixes, security updates and planned releases have defined responsibilities. Service levels and response times are agreed around the project’s needs.

Can you take over and develop an existing product?

Yes. We review the code and data structure, then provide written recommendations on what to keep and what to rewrite.

How long does the first release take?

It depends on scope. An MVP narrowed through three questions can follow a shorter schedule with weekly deliverables. We document the plan together in the first week.

Can our own team take over later?

Yes. Code, documentation and infrastructure are set up in your accounts, with a separate training period planned for handover.

How do you price the work?

We clarify the scope in our first conversation and provide a fixed-price proposal. Ongoing work can also use a monthly team arrangement.

How do you approach security and Turkish data protection?

We separate tenant data at database level and establish role permissions and audit logs from the outset. For KVKK, Turkey’s data protection law, we define the data inventory and retention periods together.

Do you build payment and subscription infrastructure?

Yes. We set up plans, trials and billing flows with the payment provider.
