What this code covers, in plain English
Our interpretation, written by the companies.house editorial team. It is not part of the official description.
Writing software to order, or building and maintaining a software product, for business or consumer use. This is the usual choice for development work where the deliverable is the software itself.
Examples
- A limited company building a booking system for a client
- A two-person team maintaining their own subscription web app
- A contractor writing application code on a client project
Codes people confuse with this one
| Code | Official description | How it differs |
|---|---|---|
| 62020 | Information technology consultancy activities | Advice, architecture, audits and implementation planning rather than writing the software. |
| 58290 | Other software publishing | Publishing and licensing software that someone else may have developed. |
| 62011 | Ready-made interactive leisure and entertainment software development | Development of games and interactive entertainment software specifically. |
62012 or 62020? Ask what the client pays for. If the deliverable is working software, 62012 fits. If it is advice, design or a plan that others implement, 62020 fits. Contractors doing both often record both codes, with the main earner first.
