Lets say you are in the field, double checking your project and you notice there's an issue. With eSUB's field works mobile app, you can snap a photo, then annotate the image, and upload it right to the cloud. Then that new image will be available to anyone in the field or office. Allowing them to review the annotated photo and then attach it to any corresponding documents.
Anyone in the field will be updated in real time as the change order is approved. Now the extra work needed to fix the issue is paid for and can get finished. Field and office, on the same page.
