Shoot Producers and abbywinters.com BV are business partners: your business provides services to our company. You invoice us for that service, and we pay your invoice (that means we both have a common interest: making shoots our customers will buy).
It’s not appropriate to say you’re an employee of abbywinters.com (you’re explicitly not!), and we’ll never present you as such.
When talking casually to models, a phrase like, “I work with abbywinters.com to make shoots” is fine. If they ask more questions, it’s fine with us to share more details – that you’re a contractor, that you’re paid for each shoot you make, that the company reimburses you for some expenses.
