When do “piddly” tasks add up?

Here's a question from Jennifer Neal at K9 Design that we posted last week on the Creative Freelancer Conference LinkedIn Group:

When is billing for PDFs and JGPs requests appropriate and when is it a throw in – we get a lot of request for these things and pulling photos from archives etc – the clients think this is no big deal but you can spend a day doing these little piddly tasks – what do people think?

Lisa Youngdahl says: “For me it depends on the client. For those who supply me with a regular income stream I will un-archive old files, or give them a jpeg of their logo for the 15th time at no charge. For those I haven't heard from in a while, especially if it was a one-shot project, I charge my hourly rate.”

Kirk Roberts says: “Deliverables should be plainly stated in the contract. Going outside of the contract without compensation is a judgment call.”

Nicholas Nawroth says: “It's a judgment call. I'd base it on how good of a client they are and how many PDFs/JPGs they are asking for. I have actions set up that make making a PDF/JPG super easy so I would have no problem tossing them a few files w/o compensation. However, if they want an entire catalog of images, I'd charge them a fee for the service.”

Heather Parlato says: “I try to define all the deliverables upfront, and usually deliver all formats agreed upon. That said, many times clients need a new size of a jpeg for placement on a site, and aren't sure who to ask–sometimes they even have Photoshop in-house. If they're regulars, I can do small conversions for free as part of our ongoing relationship, but I also ask if they anticipate needing multiple sizes and formats down the road, and alert them that this process takes time. I try to educate them on whatever they can do in-house with the final size originally delivered, or work out an agreement if they can define previously-unforeseen sizes & formats they now need for a fee.”

What do you think? Any other ideas?
