Client Testimonials
Withum’s OASyS Team supports all our accounting needs and has provided a flawless and reliable service in preparation for our Series A, and we have been working together with them ever since. As we progressed to our Series B round, an audit became necessary, and Withum assisted us in selecting an auditor and was significantly involved in ensuring a successful PCAOB audit. Their expertise brings peace of mind and confidence not only to our leadership team at Invetx but also to our Board and investors.
Over the years, Withum has provided a range of services to us, as our business needs change, including financial close and reporting, preparation of our tax provision and returns, and audit support. Currently, Withum provides administration of our payroll and accounts payables processes. For an early-stage company such as ours, cash management is key to our success. We are a lean team, but together with Withum, we maintain consistent processes and controls to achieve operational success.
Withum's OASyS Service Team reduced the time I spent on accounting work, minimizing my worry about the accounting records. The Team also increased efficiencies by helping us implement Expensify. Using Withum has freed up an enormous amount of time, allowing me to focus on my semi-retirement and the more critical aspects of the business.

We rely on the Withum Outsourced Accounting Services Team to provide complete accounting services from bill payment and processing to financial statement reporting which both our leadership teams and investors rely upon. In addition to these services the Withum team assists with our forecasting, cap table management, financial due diligence and a variety of other matters which arise in the course of running a business. Overall, our costs for these services are significantly less expensive than hiring our own full-time employees to staff a department. Further, when matters arise where more sophisticated financial expertise is required, we are able to leverage our team and utilize the services of other financial and tax professionals employed by Withum to provide needed assistance.
