Adobe has moved its Acrobat.com Web-based productivity services out of beta and has made paid-for subscriptions available to users based in North America. As well as providing general office tools such as word processing and presentation tools, Acrobat.com includes sharing and collaboration tools designed to appeal to creative agencies who want to work more smoothly on versions of projects with colleagues, clients and freelancers.

The company also will introduce a spreadsheet service called Acrobat Tables, which goes into preview release on Monday, said Erik Larson, director of marketing and product management for Acrobat.com. Other services already available are a word processing application called Buzzword; a Web meeting application, Adobe Connect Now; and Presentations, an application akin to Microsoft's Office PowerPoint for building presentations.

Web-based services that compete with packaged software like Microsoft Office and IBM Lotus are becoming more prevalent; Google and others also have offerings in this market. Adobe, based on its history in the document-creation and management market, has a strong position to rival Office among business users, at whom Acrobat.com is aimed.

Adobe is offering two subscription levels for Acrobat.com -- Premium Basic and Premium Plus. Both are available as either a monthly or annual subscription, Larson said.

The basic level is US$14.99 a month or $149 a year and includes conversion to PDF for 10 documents a month, as well as the ability to hold Web meetings with up to five participants. The plus level costs $39 a month or $399 a year, and offers unlimited PDF conversions and Web meetings for up to 20 participants. Adobe offers telephone and Web support for both subscription levels, Larson said. A special introductory promotion that lasts until July 16 will give customers $15 off the annual plan and $50 off the plus plan, he added.

UK pricing and availability has yet to be confirmed.

Adobe also will still offer a free basic version of Acrobat.com services in addition to the subscriptions.
