Handheld computers are fun, although the CFO is unlikely to approve their purchase unless there are better reasons to purchase. Here are some very real reasons for your consideration: Cash management - quickly invoice for work done, invoice accurately and avoid disputes Better fuel mileage - dispatch work crews to the closest job, on the right routes and send them out with the right tools and supplies the first time. Improved productivity - avoid wasted driving time, and inefficient paper work Improved customer service - respond faster, bring the right tools and parts the first time Visibility into inventory use - monitor parts and inventory used and apply these to the right customer accounts. Make sure you aren't losing parts and supplies to theft and loss. Reduced liability - accurate documentation of work, wirelessly synchronized with the headquarters database for storage. Improve quality and performance - compare times, work productivity, customer satisfaction and profitability
