"How much will it cost?" is the first question almost every business owner asks before commissioning custom software. The honest answer is that it depends on what you need built and how it is built. Two systems with the same name, such as "inventory software" or "ERP", can differ many times over in effort. This guide explains, from a technology point of view, what actually drives the cost of custom software in Pakistan, so you can plan a realistic budget and compare quotes fairly.
1. Scope and features: the biggest cost driver
Most of a software budget is team time, and team time is driven by scope. Every item below adds design, development and testing work:
- Modules: sales, purchases, inventory, accounts, payroll, production, reporting. Each one is a small system of its own.
- User roles and permissions: an owner, a manager, a cashier and a warehouse user each need different screens and access rules.
- Branches and locations: a single shop is simpler than a system that syncs stock and sales across several branches or warehouses.
- Business rules: discounts, approvals, tax rules, credit limits and custom reports all need logic and testing.
- Data migration: moving old records from spreadsheets or a previous system takes cleaning, mapping and checking.
Clear requirements reduce cost. Time spent mapping your real workflows, documents and approvals before development starts usually costs less than changing direction halfway through.
2. Platform: web, Android, iOS or desktop
Where the software runs affects how much has to be built:
- Web application: runs in a browser on any computer, and on phones if it is built responsively. One codebase serves everyone, and updates go live for all users at once.
- Android app: useful for sales teams, delivery staff, field visits and barcode scanning on the go.
- iOS app: needed if your customers or managers use iOS devices. A separate native iOS app is a separate build.
- Desktop software: sometimes chosen for offline counters or hardware-heavy setups, but it needs installing and updating on each machine.
Each additional platform adds work unless a cross-platform approach is used. Decide which devices your team and customers actually use before you ask for quotes.
3. Technology stack choices
The tools a system is built with affect development speed, hosting needs and long-term maintenance. Common choices include:
Backend and web
- Laravel (PHP): a mature framework well suited to business applications, admin panels and APIs.
- React: a JavaScript library for fast, interactive web interfaces such as dashboards and POS screens.
Mobile
- Flutter: one codebase for Android and iOS, which can reduce the cost of supporting both platforms.
- Native Android (Kotlin): best when the app needs deep device features, heavy offline use or maximum performance on Android.
Databases
- Relational databases such as MySQL or PostgreSQL: the usual choice for invoices, stock and accounts, where data must stay consistent.
- Local or offline storage on devices: needed if users must keep working without internet and sync later, which adds complexity.
The "best" stack is the one that fits your requirements, your budget and the team that will maintain it. A good vendor should explain why they chose it.
4. Integrations with other systems
Connecting to outside systems is often where hidden effort sits:
- FBR Digital Invoicing (PRAL DI API): for sales tax registered businesses this is a core requirement, not an add-on. It involves validating invoice data, testing in the sandbox and moving to production. See Logic Layer FBR Digital Invoicing.
- Payment gateways and mobile wallets: online payments, payment confirmation and reconciliation.
- SMS and WhatsApp messaging: order confirmations, payment reminders, OTPs and invoice sharing.
- Banks, existing accounting software and hardware: barcode scanners, receipt printers and scales.
Each integration needs development, testing against the other system and handling for when that system is slow or down. Ask early whether a quote includes the integrations you need.
5. UI/UX design
Good design means staff can use the system with little training and make fewer mistakes. A proper design phase (screen flows, mock-ups and feedback from real users) adds time up front, but it usually saves revisions and support later. Simple, fast screens matter most for daily, high-volume tasks such as billing.
6. Security
Business software holds sensitive data: sales, customers, salaries and tax records. Security work includes secure login, role-based access, encrypted connections, protection against common web attacks, audit logs showing who changed what, and regular backups. This is not optional, and it takes development and testing time.
7. Testing and quality assurance
Software that handles invoices, stock or payroll needs to be right first time. Testing covers individual features, full workflows, different devices and browsers, and integrations such as FBR invoice submission. More critical systems need more testing.
8. Deployment and hosting
Once built, software has to run somewhere. Deployment includes setting up servers or cloud hosting, domains and SSL, backups, monitoring and, for mobile apps, publishing to the app store. Hosting is a recurring cost on top of development, and it grows with the number of users and the amount of data.
9. Maintenance after go-live
Software is never truly "finished". After launch it needs security updates, bug fixes, small improvements, and changes when laws or integrations change (FBR rules, for example). Plan for ongoing support from day one, and ask each vendor what their support covers and how it is charged.
MVP or full build?
You don't have to build everything at once.
- MVP (minimum viable product): start with the few features that solve your biggest problem, put them into real use, then add more based on feedback. This lowers the first investment and reduces the risk of building features nobody uses.
- Full build: suits businesses with clear, stable requirements that need the complete system from day one, for example when replacing an existing system.
Fixed price or time-based pricing?
Software houses generally quote in one of two ways:
- Fixed price: one agreed price for a clearly defined scope. Good when requirements are clear and unlikely to change. Changes outside the scope are quoted separately.
- Time-based (time-and-materials or a dedicated team): you pay for the actual time spent. More flexible when requirements will evolve, but it needs closer tracking of budget and progress.
Whichever model you choose, make sure the proposal states what is not included: hosting, third-party licences, data migration, training and post-launch support.
Custom build or ready-made software?
Custom software isn't always the right first step. If your needs are standard (accounts, inventory, purchases, sales), a ready-made system can get you running faster. You can then add custom work only where your process is truly different. Logic Layer offers both: a ready-made Logic Layer ERP for core operations, and custom software, web application and Android app development for workflows that off-the-shelf tools can't handle.

Checklist before you request a quote
- List the processes you want to digitise and who uses each one.
- Collect sample documents: invoices, purchase orders, reports.
- Note every system the software must connect to (FBR, bank, payment gateway, SMS or WhatsApp, existing software).
- Decide on web, Android, iOS, desktop or a combination.
- Decide whether to start with an MVP or a full build.
- Ask for the quote to separate development, hosting, licences, training and ongoing maintenance.
