I'm a graphic designer and front-end web developer. I was recently approached to design and build a simple brochure website for a language school to showcase their courses. The school is currently having a custom piece of software developed to aid students during the learning process.
The client is now talking about using the same design style for their software. This means I'll be designing an additional UI (fields, buttons etc). Would you advise I charge an annual license fee for the design + my time for the actual design work? The language school will rely on the software for each module.
I'm used to designing simple portfolio websites, so your advice would be greatly appreciated before I provide a quote.
