People are essential to financial operations. But when the operating structure isn't clearly defined, the firm can become unnecessarily dependent on individual employees or outside providers for knowledge, coordination, and continuity.
Without clearly defined processes, the firm depends on individual employees or outside providers to know how financial work is performed and how exceptions are handled.
Without a defined sequence and cadence, the firm depends on individual employees or outside providers to coordinate when financial work happens and how it fits together.
Without clearly defined responsibilities and handoffs, the firm depends on individual employees or outside providers being available to keep financial work moving when it needs to happen.
FINS is a financial operating standard for small project-based firms. It defines how recurring financial work is organized, sequenced, and performed across the firm’s people and tools.
FINS gives the firm a defined operating structure for financial work—establishing what needs to happen, when it happens, who is responsible, and how each process connects. The people performing the work remain essential, but the system no longer depends on individual knowledge and coordination to hold everything together.
By performing financial work through defined workflows and a consistent monthly rhythm, responsibilities become clearer, handoffs become easier, and work can continue when individual employees or outside providers are unavailable. The result is a financial operation that is more consistent, dependable, and resilient over time.

FINS organizes financial work into a simple monthly rhythm. The same structured workflows are repeated each cycle to keep financial operations current, consistent, and under control.

STEP 1 – START CYCLE
Each cycle begins at a defined point in time—typically the 5th or the 20th—establishing a consistent rhythm for financial work.

STEP 2 – RUN WORKFLOWS
Work is performed through defined workflows—such as recording transactions, paying vendors, reconciling accounts, and billing clients.

STEP 3 – REPEAT CYCLE
The cycle repeats twice each month, keeping financial work current, organized, and aligned without the need for catch-up or rework.
FINS isn't something you implement and set aside. It provides an operating structure your firm can continue to use, reference, and maintain as financial work and circumstances change.
Put recurring financial work into defined workflows with clear responsibilities, sequencing, and timing—creating an operating structure the firm can rely on.
Use defined workflows and a consistent monthly rhythm to keep billing, payments, reconciliation, reporting, and other recurring financial work current.
Use supporting resources, exception guidance, and implementation clarifications to address unusual situations while keeping financial work aligned with the system.
Use maintained standards, guidance, and resources as FINS continues to improve—keeping the firm's financial operating system current and dependable over time.
You can adopt the FINS Standard independently or implement it with guidance, depending on the needs of your firm. Guided Implementation builds on the standard with structured onboarding, implementation guidance, and ongoing support.
