Hi all first time post so appologies if I get something wrong. If Ive designed a logo for a new Curry House outlet thats expanding to open a new branch and they are really happy with the work, do I charge them by how many hours Ive actually worked or more as this will be their recognised name/brand identity for a long time? I understand we should have sorted this before the work started but hes normally ok with what I say. Hope that makes sense!
