It goes without saying, but retakes are not free ad infinitum.
Here are my terms and conditions for edits and retakes.
I allow for one complete re-read of your script, and two rounds of minor amends with 30 days.
Beyond that, changes are chargeable depending on the amount of re-recording required - with a minimum charge of £25
Complete re-reads will be charged at 50% of the original quoted rate and will 'reset' the clock on edits - so you'll get another free re-read and two rounds of minor amends.
If edits are required that are caused by mistakes in my read or technical issues with the recording they are, of course, unlimited.
Payment terms are 30 days from invoice date, or client approval of audio whichever occurs first
