For business use like websites and company profiles, you likely need a commercial usage/license agreement rather than a simple personal print release. A personal print release usually only covers making prints for private use, while commercial use should be explicitly authorized in writing.

Community recommendations included:

• ASMP (American Society of Media Photographers), which offers tutorials and sample forms.
• Easy Release, a mobile app that can generate release forms.
• e-model.net, which was suggested as a sample release source.

Also make sure you distinguish between:

• a copyright/license granted by you to the client for specific uses, and
• a model release, if recognizable people appear and the images will be used commercially.

If the portraits are for a company’s promotional use, the safest approach is a written license describing the allowed uses clearly.
