How long does a custom software project take?

MVP-scope ERPs and internal tools ship in eight to fourteen weeks. Full multi-module SaaS platforms typically take twelve to twenty-four weeks. We ship in two-week sprints with usable software at the end of every sprint — you start using it before it is 'done'.

What is the cost range?

Most custom-software engagements at DevKey land between PKR 800,000 and PKR 4,500,000 depending on scope. Bigger drivers are number of modules, integrations, user roles, and reporting depth. We always send a line-itemized proposal after the discovery call.

Who owns the code and data?

You do — from day one. The repository sits in your GitHub organisation. The database lives on your Supabase or AWS account. If you ever want to bring it in-house or move agencies, you take everything with you.

What happens after launch?

Custom software is most useful in year two when your business has evolved and you want to add modules. We offer monthly retainers that cover hosting management, bug fixes, small feature work, and quarterly architecture reviews. Most clients keep us on for the long run.

Can you integrate with the SaaS we already use?

Yes — and we usually do. Most custom software at DevKey integrates with the client's existing accounting, payment, email marketing, CRM, and communication stacks. We write clean API integrations and use Make or n8n where it makes sense for low-code glue between systems.

Overview

Stop bending your business to fit someone else's software

Every growing business hits a wall where off-the-shelf SaaS stops fitting. Five spreadsheets feeding three different SaaS tools, manual exports between them, and one person who knows where the source of truth lives. That is when custom software pays for itself — often in months, not years.

We build bespoke business software for clients across fintech, transport, healthcare, and professional services. We start by mapping the workflow you actually run today, identify the three or four places where time and money leak, and design a system around those — not around a feature checklist.

Our custom builds use the same modern stack we use for everything else (Next.js, Supabase, Postgres, TypeScript), with Django and Python in the mix when the domain demands it. We design for change: by the time the system goes live, you usually want to add a module — and you can, without rewriting the whole thing.

Workflow-first design

We map your real operations before drawing any UI. Software is the artefact, not the goal.

Postgres-first data

Clean, typed schemas you can query directly. No vendor lock-in, no mystery JSON blobs.

Modular from day one

Add the next module without touching the last one. The product evolves as your business does.

Yours, not ours

You own the code, the data, the infrastructure. We are your team — not your landlord.

Frequently asked questions

The answers prospective clients usually want before the first call.

Buy off-the-shelf when your workflow is generic and matches what a SaaS already does well. Build custom when your workflow is what differentiates you, or when you have outgrown the SaaS and the workarounds are costing more than the subscription. The honest test: count the spreadsheets and manual handoffs you do between SaaS tools. If it's three or more, custom usually pays back inside twelve months.
