About Accounting & Bookkeeping Services

HR Liaison and Payroll Services

Happy employees are the key to success. Keep them happy by always making payroll on time.


As your team grows and shifts, the complexity around employee files, compensation and payroll increases. Employees come and go, get bonuses or commissions, go on leave, change roles. Compensation motivates, and incorrect pay creates relationship risk. Our role is to ensure the employee files are up to date and that payroll gets run correctly.

High-Growth Clients

Evan Rosenbaum

CPO / Co-Founder, Genies

"Mike Long has been a fantastic member of the Genies executive team. He has helped us grow from a few employees to over 30 by putting in place practices and systems to enable and sustain growth. His insights have helped us scale our revenue, track spending, and do effective financial projections. Mike and team are key parts of the Genies growth story."

Jon Gowa

CEO, Bloom Automation

"Coffinity has been absolutely essential in allowing our robotics start-up to focus on the technology, not the day to day financials. As a CEO, and a VP of Engineering, my roles are already split thin. Unloading everything from our book-keeping to purchase orders and accounts payables, and even proforma generation and counseling, allows us to focus our time on the nuts and bolts."

Jason Campbell

Co-owner, Slack Tide

"Mike and Annmarie have been a trusted and integral partner in the growth of our company. Their knowledge and guidance from the first day we opened to now has helped our company grow exponentially in the 4 years we have been in business. We could not be happier with their work and focus on helping us grow."
