The First 30 Days

An interim engagement is judged on what happens immediately. Whatever the trigger—a departed CFO, a stalled close, a transaction in flight—the first month follows a consistent arc:

Cash Visibility

A 13-week cash flow forecast and a clear view of the liquidity runway—the first question every sponsor and lender asks

Close & Reporting Stability

Get the month-end close back on schedule and the reporting package landing on the sponsor's calendar, every month

Stakeholder Reset

Re-establish credible communication with the sponsor, lenders, and auditors—no surprises, and a single owner for every open item

Team & Systems Assessment

An honest read on the finance organization and its systems, feeding a prioritized roadmap—and, where needed, the permanent-hire profile

Frequently Asked Questions

When should a company engage interim finance leadership?

Common triggers: a CFO departure with no succession plan, a controller struggling with a first institutional close, audit preparation overwhelming the internal team, M&A activity requiring dedicated finance resources, a system implementation needing finance subject-matter expertise, or parental leave coverage for key personnel.

What engagement types does Surge Finance offer?

Four models: interim CFO (executive leadership during transition, transaction, or vacancy), interim controller (month-end close management, audit preparation, process stabilization), project-based support (discrete initiatives with defined scope and timeline), and staff augmentation (additional capacity during peak periods or special projects).

How quickly can an interim CFO or controller start contributing?

Immediately. Recruiting a permanent hire takes months; we deploy experienced professionals who step into your environment and contribute from day one, with no learning curve on sponsor expectations—and a clean handoff when the engagement ends.

What backgrounds do Surge Finance professionals have?

Senior professionals with Big Four and industry backgrounds who already understand private equity reporting cadences and sponsor expectations.

What is the difference between an interim CFO and a fractional CFO?

An interim CFO is a full-time executive engaged for a defined period—typically covering a vacancy, transaction, or turnaround—while a fractional CFO provides ongoing part-time leadership, often a few days per month. PE-backed companies in transition usually need interim coverage: the monthly reporting cadence, lender obligations, and deal activity demand full-time attention. Surge Finance provides full-time interim CFOs and controllers, plus project-based support where part-time capacity is the right fit.

What does an interim CFO focus on in the first 30 days?

Cash first: a 13-week cash flow forecast and visibility into the liquidity runway. Then close stabilization, so the monthly reporting package lands on the sponsor’s calendar; a reset of lender and sponsor communication; and an assessment of the finance team and systems that feeds a prioritized roadmap for the rest of the engagement.
