Recently we took in an order where the piece was 23x35, but was accidentally entered in the system as 23x25. We didn't catch this until it came time to build the frame (I always re-measure art before building frames Just In Case). Of course, changing the size in the system would raise the price quite a bit. So, two kwestions: (1) What do you do in this case? Honor your initial quote and eat the cost? Call the customer and tell them there was a mistake and it'll cost more? Offer to split the difference? Other ideas? (2) Any ideas as to how to prevent this from happening in the future? The problem is most likely to rear its head on busy days when we're in a hurry to wrap it up with one customer and get on to the next, so double-checking the measurements while the customer is there might not be an option... Thoughts?
