I always try to provide pictures next day or maximum within 3 days. If it is an important event I give 5-10 pictures even on the same day (and doesn’t matter what time I finished).
Why I deliver pictures quicker than other photographers? Because:
? Actual. People want to share pictures from the wedding or the trip today, not after 3 months;
? My camera has a wi-fi. I can transfer pictures to my phone very fast and edit there;
? I know Photoshop/Lightroom very well plus have mobile versions;
? I photoshoot correct from the beginning, I don’t need to spend hours for post processing.
