Electronic signing of business documents is really convenient and saves a huge amount of time for both the originator and the recipient. Using a subcontract agreement as an example you can save 20-30 minutes per document as you eliminate; upload, email cover, download, countersign, upload again, email again, filing and endless follow up.
But… before you go down this track ensure that you are covered legally in the event of a dispute. Both New Zealand and Australia have a specific Act that covers the electronic signing of documents so compliance is essential. Carefully research the solution you are considering as there are a number of systems out there that simply are not compliant with local legislation and will not stand up if there is a legal dispute. A great solution if you get the research right!!.
