What Is a Digital Platform?
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 |
How Much Does Digital Platform Development Cost?
Our rates start from $35 per hour and projects start from $1,000. The cost of a platform depends mainly on:
- the number of user roles and portals (one customer portal or ten role-based portals);
- integrations with payment, accounting, courier or ERP systems;
- web only, or web plus iOS and Android apps;
- reporting, AI features and data migration.
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.
How to Choose a Digital Platform Development Company
- Ask for platforms in production, not only designs, and talk to their users if you can.
- Check they cover back end, web, mobile, cloud and support, so one team owns the whole platform.
- Agree that you own the code and have access to it at all times.
- Ask how they plan releases, test and report progress.
