We just finished our company sale last month. Setting up the data room was actually the easiest part of the whole process. Found here is the website that helped us pick the right system for our size. Nothing fancy - just uploaded our contracts, financial reports and employee info. Took about 3 days to organize everything. The buyers liked that they could find stuff without emailing us constantly. Cost about $900 for three months which was way cheaper than our lawyer fees. If you're selling your business, don't overthink this part - just pick something simple that works and focus on the bigger issues like negotiations. The main thing is having all your documents in one secure place
