Where Rosy Small Business Services Started.

Lauren McMaster has been providing bookkeeping and office management support to small Melbourne businesses for over 20 years.

She began her bookkeeping career in 1996, while still in highschool, where she worked for a local veterinary practice. Her services were critical, as there was previously just one vet who was not only running the entire business, but also juggling bookkeeping and administration duties.

It was these experiences that gave Lauren a passion for helping small businesses, which she would carry throughout the rest of her career. For example, Lauren later used her abilities as an office manager to help a small IT company achieve great success over the course of a decade. During this time, Lauren worked in many areas including project management, support coordination, bookkeeping, payroll, human resources and procurement and accounts payable and receivable.

She also used that time to develop her own skills, becoming proficient in both MYOB and Xero accounting systems, to the point where she is a Xero Certified Advisor – Certificate IV in Accounting and Bookkeeping, BAS Agent

With her degree in computer science, Lauren embraces all of the efficiencies that cloud accounting systems provide and remains enthusiastic about the use of these technologies in the future.

After many years of performing bookkeeping and general admin for small businesses, Lauren decided to launch her own business offering these services to other start-ups, sole traders and small businesses.

Through Rosy Small Business Services, Lauren is able to use her finely-honed skills and experience to provide improved bookkeeping and administrative processes to forward thinking small businesses.

Recent projects Rosy Business have completed include :

  • Implementation of Xero

  • Trading Name changes (including liaising with suppliers to obtain new credit terms and contacting all clients with regards to new bank details)*

  • ABN changes (including sole trader to company structure changes)*

  • Preparation of books for annual NFP audits.

  • Implementation of inventory reporting

  • Implementation of billing systems as Wise-Pay, Stripe and Square

  • Implementation of employment management systems such as Employment Hero

  • SLI reporting alignment audits

  • Implementation of accounts service boards in ConnectWise Manage

*Note Trading name and ABN changes are completed in consultation with accounting professionals. We work with many accountants to support our clients.
