I am also interested in something like this. It would be nice to include an image of the product I'm billing for.
Hey @Azel ,@RobC, I am afraid it is not currently possible to attach photos to invoices. This is something that may be introduced at some point, it has been asked for before. Since Wave doesn't currently offer this feature, we'd really appreciate your insight on how it'd be a game changer! The more feedback we can bring to our product team on features, the better! Thanks
I'm a graphic designer, so for me it would be nice to attach the "deliverable" artwork to the line item description. It doesn't have to be the actual final file, but it would be nice to include a thumbnail image of the logo or graphics I delivered to them. (Not your or my concern, but my client has to submit my artwork with my invoice to management for approval. This would help alleviate that manual step since she has to match up which artwork goes to which invoice. I realize this is a specialized case, but it would be a convenient reminder for all clients.)
I can see how it would also be helpful to include a picture a physical product for those that have provided it, too.
