A company can help to boost staff morale if its human resources side is functioning well — and that is where a Tensor personnel system comes in. Tensor's personnel software boasts many additional features that will save time and aid strategic planning. The Letter Writer feature includes mailmerge functionality. There are three versions: Small Business, ideal for companies employing 50 people or less; Lite, a multi-user version, for up to 250 people; and Enterprise, a multi-user, multi-site edition that has no employee limits.
