I have a web design project that for various reasons was never completed (i.e the client never received any final files, the contract was cancelled and is very unlikely to be restarted). The project was however quite extensive and a significant way to being completed. (To the point that the site had been built in WordPress with a number of custom post types and other custom functionality, and integrated with 2 external APIs.)
I now have a client who wants an almost identical project. With regards to design, the branding is obviously different but with a very similar style and the site structure would be almost identical so a very large proportion of the previous project could be reused and design and development time would be drastically cut.
Assuming I want to reuse the old project for this new client - How should I approach this with the client and how should I charge for the work?
The way I see it, I have a few options:
I am completely honest with the client and explain the situation. I charge based only on the amount of new work done (or at least close to this). This would be the best option from the clients perspective, but not very beneficial for me.
I am completely honest with the client but charge for the full project, as if starting from scratch. The risk with this is the client may not like the idea of getting second hand work without any cost benifits, I could lose the contract, not get any use out of the previous work and possibly make a bad impression on the client.
I use the previous work without telling the client and charge as if starting from scratch. This would be the most beneficial for me. My only problem is it feels a bit dishonest and unfair on the client.
I don't think using the previous work without telling the client and charging a reduced rate is an option. I would either have to come up with a fake reason for discounting the price, which feels just as dishonest, or I set an expectation for lower prices in the future.
So how do I proceed?
