Read our guide to client portal development cost.
A digital platform is software where several groups of users, data and business processes meet in one place, such as a SaaS product, a customer portal, a marketplace or an ERP. Unlike a website, it has logged-in users, roles and permissions; unlike a single app, it usually serves several apps from one back end.
| Website | App | Digital platform | |
|---|---|---|---|
| Main job | Inform and win leads | Serve one group of users | Connect several user groups and processes |
| Users | Visitors | Customers or staff | Customers, staff, partners and admins with roles |
| Examples | Company site | Ordering app | Courier ERP with client portal, multi-branch POS platform |
Our rates start from $35 per hour and projects start from $1,000. The cost of a platform depends mainly on:
Most platforms start with an MVP. A starter MVP costs $3,000, or $1,500 when you claim our free clickable design of 5–6 key screens; larger platforms are quoted after scoping. See client portal development cost and custom software development cost for typical ranges.

Real platforms in production, built by our team:
Order management, dispatch, warehouses, returns, a client portal and FedEx, DHL, TCS and M&P integrations on ASP.NET Core and SQL Server. Live in production. Read the case study.
Online ordering, POS, menus, payments and inventory, used by 5+ restaurants with 50+ daily orders per branch. Read the case study.
Healthcare and cannabis SaaS with AI workflows and microservices on React, Python, .NET and GraphQL. Read the case study.
Grant discovery, eligibility analysis and application management with Next.js, Python and large language models. Read the case study.
For a growing organisation we built a complete HR management platform: a web admin dashboard (React and Angular) for employee records, attendance and office operations, a Flutter mobile app for attendance and leave requests, and an ASP.NET Core API behind both. Result: more than 5,000 active users.

Best for MVPs and projects with a clear scope. You agree on price, timeline and features before development starts.
Flexible for products that will evolve. You pay for actual development time and can change priorities after every sprint.
Add experienced platform developers, designers and QA engineers to your team on a monthly basis for long-term development.
