About this practice

Manuel Cosme Jr. opened a bookkeeping and tax practice in January 1990 after working for a CPA firm; payroll was added in the mid-1990s, at one point covering twelve states, and the firm reckons it has served more than 500 businesses since. Ana Pellecer, who co-founded PSBS in its current form in July 2007, is president and an Enrolled Agent. Susan A. Thomas came from a CPA's payroll desk in 2001 and handles workers' compensation, union and prevailing wage reports alongside the standard quarterly filings.

Bookkeeping runs on a pick-up and delivery arrangement against a customized checklist, with monthly bank reconciliations and a set of financial summaries including a profit and loss comparison against the prior year. Returns cover individuals with rental property or a small business, plus partnerships and corporations. Consulting centers on choosing between sole proprietorship, partnership, corporation and LLC. Notary service is available, and the office is open year-round. Se habla espanol.
