We understand the limitations of tax technologies and software; that is why the team at Amphitrite Advisory is future-focused, working hard to identify data-driven processes that are technology-enabled and streamlined. We started Amphitrite to serve the corporate tax community with a single purpose: Service with Excellence.
Here is how we do it:
We implement ONESOURCE, Corptax, and Longview tax provision softwares with minimal adoption time so that you can start to experience the incredibly powerful results immediately.
Reduce the likelihood of human error and increase your team's overall efficiency. Automate your essential processes, so your people can give their full attention to the tasks that require their unique skills. You never need to start with a blank slate. We have a library of automation tools that we can use with the tax provision softwares.
Our comprehensive assessment evaluates your current tax processes, technology, and team structure to identify opportunities for improvement. We deliver actionable recommendations that enhance efficiency, reduce risk, and position your tax department as a strategic business partner.
We charge a fixed fee for tangible and meaningful milestones we set together. As long as the engagement assumptions remain unchanged, we consider everything in scope. We believe our clients need to see results every step of the way. We earn fees when milestones are achieved rather than hours incurred. Our people get paid for results; our clients get invoiced by results.
Taking an agile approach to software implementation means the project is finished on time and on budget. This approach is iterative, incremental, flexible, and interactive with staff on demand and standardized workpapers.
Our approach to working with our clients is personalized and collaborative – working hand in glove, understanding our client's goals, expectations, and vision for success. We believe in joint responsibility and accountability that includes integrated client onboarding, training, and open knowledge-sharing. Our clients can immediately leverage our tools with confidence and know we are there for them every step of the way.
We designed a suite of powerful automation tools and accelerators to bring greater transparency into the sources and output of data for corporate tax teams. These tools increase accuracy and controls while reducing the amount of time required to reach essential KPIs, enabling team members to focus on the tasks that most need their attention and skills.
As our client, you can contact us with questions, troubleshooting, and other support without having to worry about extra add-on costs. This is part of our service and our dedication to helping you reach your goals during the engagement and beyond.
We are not a big firm and don't pretend to be. It's not about capturing the longest client list; it's about creating a long list of successful clients. We maintain a client scale to ensure each client gets the value they deserve.
Our approach is to bring knowledge-sharing to the forefront of our service and the corporate tax community. We want our clients armed with the knowledge to bring out the best in their people and influence the broader tax community. Therefore, we created a "Forum" to encourage the knowledge-sharing and co-creation of tools among the corporate tax community – we feel knowledge is that important! A strong knowledge-sharing community coupled with the right technology and tools – more power behind the punch!
