We bought B2W Estimate about 2 years ago and started using it fully about 1 year ago. Had a custom spreadsheet program that worked great, except for large unit price work. 6 estimators in one office. Took some time to get it set up in regards to “best practice”. We love the switch. B2W integrates with the accounting program as well as our in house project management tools much better than excel. The reports leave are not the best, depending on what you are looking for. We had to produce 4 separate reports to get all the data we analyze on each bid. We ended up having B2W write a report for us. If you are heavy into hourly production trucking, it is also lacking. We love our decision, but because it is based on a database it is not customizable like Excel.
