I often send out multi-item or multi-quantity estimates (100 items or 500 items would have a different price per unit) and I would like to be able to prevent an estimate from automatically totalling the prices. Can’t see a way to do it currently. Would it be possible to make it doable?
Hi Kate 
Welcome to our Forum! Thank you very much for your post, I hope I can help.
This sounds like it might be a feature request for the FreeAgent application itself, rather than for our API. This forum is designed to allow users who are creating third party applications that use our API, to discuss issues they are experiencing, or request features for the API itself.
If you get in touch with our Support team at support@freeagent.com, they will be able to either help you achieve the effect you are looking for, or direct this to the correct team as a feature request.
Kind regards,
Katie
