Interim Controller FAQs
Answers to your most frequently asked questions.
How is 8020's Consulting model different from other firms?
Unlike traditional firms that rely on junior teams or contractors, we embed highly experienced operators directly onto your team.
Our consultants are chosen from the top 10% of the market and are our full-time employees who combine deep technical expertise with hands-on operational experience, averaging 20+ years in the field.
This means you get the perfectly chosen expert for your specific needs, who operates as an extension of your team, drives immediate results, and elevates your entire finance operation through their proven methodologies and industry knowledge.
What makes your consultants different from other firms' consultants?
We exclusively hire senior finance professionals who have both led and executed complex financial operations in many real-world scenarios.
Each consultant must demonstrate exceptional technical expertise, strategic thinking, and a proven track record of success across challenging business environments.
Our consultants have actually "sat in the seat" - meaning they've held senior finance positions and truly understand the day-to-day challenges of running finance operations. This combination of technical knowledge and practical experience matched to your specific challenges enables them to deliver superior results.
How do you match consultants to specific client needs?
Our leadership & Client Services teams are made up of experienced finance and accounting consultants themselves, so they actually viscerally understand what your challenges are and who's best suited on our team to solve them.
We also use a precise diagnostic approach to match the right expert to your specific challenges by carefully evaluating project requirements, industry context, and technical needs to deploy consultants with directly relevant experience.
Our very selective hiring process maintains a diverse pool of specialists across many finance disciplines, ensuring we can address any financial challenge with the exact expertise needed. While out on a project, each of our consultants can leverage the collective knowledge & experience of all ~100 experts on the team whenever needed.
This strategic matching process, refined over years of successful engagements, maximizes project success and client satisfaction.
What is the role of an interim controller?
An Interim Controller provides financial leadership during times of transition or change, overseeing core functions such as month-end close, reporting, internal controls, and compliance.
They stabilize daily operations while improving systems, processes, and team capabilities, ensuring both continuity and long-term financial efficiency.
How fast can an Interim Controller start working?
Interim Controllers can typically start within a few days to one week, depending on onboarding logistics and access to systems.
They integrate quickly to assess priorities, stabilize operations, and begin driving improvements across finance and accounting functions with minimal ramp-up time.
What makes your Interim Controllers different from traditional accounting consultants?
Interim Controllers differ from traditional consultants by taking a hands-on, embedded leadership role within the organization.
While consultants often advise from the outside, Interim Controllers lead daily operations, manage teams, and implement strategic improvements directly.
Their experience spans technical accounting, systems integration, and team development, offering both immediate impact and lasting operational value.
How quickly can an Interim Controller start making an impact?
Interim Controllers typically begin making an impact within the first week by stabilizing key functions such as accounts payable, payroll, and reporting.
They quickly assess pain points, streamline processes, and implement early-stage improvements to improve efficiency, reduce risk, and support business continuity.
What types of companies or situations are best suited for an Interim Controller?
Interim Controllers are well-suited for companies undergoing leadership transitions, rapid growth, system changes, or audit preparation.
They are especially valuable in organizations that need both technical accounting expertise and hands-on operational leadership during periods of change or complexity.
These services apply across industries and company sizes.
What specific improvements can I expect from an Interim Controller?
Interim Controllers drive improvements in month-end close efficiency, internal controls, reporting accuracy, and cash flow management.
They also enhance audit readiness, manage complex transactions, and implement sustainable processes that support long-term financial performance across the organization.
How do Interim Controllers work with existing finance team members?
Interim Controllers collaborate closely with internal finance teams to improve skills, share best practices, and document key processes.
They often mentor team members, conduct gap analyses, and ensure knowledge transfer to support sustainable improvements and build long-term capability within the organization.
What ERPs and financial systems do your Controllers have experience with?
Interim Controllers have experience with leading ERP and financial systems such as SAP, Oracle, NetSuite, and QuickBooks, along with payroll platforms like ADP, Paycom, and Workday.
They can optimize current systems, lead new implementations, and ensure controls and reporting processes are efficient, accurate, and scalable.
Is a controller higher than a CFO?
No, a controller is not higher than a CFO. The CFO (Chief Financial Officer) holds the top financial leadership position, responsible for overall financial strategy, planning, and stakeholder communication.
The controller typically reports to the CFO and focuses on accounting operations, financial reporting, and compliance.
While both roles are senior, the CFO has broader strategic and leadership responsibilities.
