How to Find the Best Finance as a Service (FaaS) Partner

If you're here, you may have already found them. Use our checklist to ensure alignment.
Updated: June 17, 2025

Finance as a Service (FaaS) has become the preferred model for companies that need enterprise-grade finance and accounting (F&A) without building a large in-house department. 

The right partner supplies people, process, and technology in one subscription, freeing leaders to focus on strategy instead of spreadsheets. But how do you separate the truly strategic partners from basic outsourcing vendors? 

Use the checklist below, then see how Consero raises the bar with AI-enabled technology, flexible engagement models, and a full continuum of services.

1. Start With Self-Assessment

Clarify your gaps and goals. A precise inventory of needs keeps you from over- or under-buying and lets you compare providers on apples-to-apples terms.

Service Requirements Assessment
Do you need help with core bookkeeping, month-end close, and compliance, or deeper capabilities such as FP&A, M&A support, or operational KPIs?
Investment Readiness
Are you preparing for private equity investment or a potential exit that demands audit-ready statements?
Historical Data Quality
Is cleanup work required to repair historical errors?
Governance and Compliance
What level of security, governance, and data visibility will satisfy your board and regulators?

2. Evaluate a Provider’s “Three Ps”

People
Do they have a deep bench (bookkeepers, controllers, FP&A analysts, and CFO- and VP-level advisors) who know your industry?
Will you get senior oversight or junior staff learning on the job?
Process
Are month-end closes completed in days, not weeks?
Do they document controls that pass audit and SOC 1/SOC 2 reviews?
Platform
Is the tech stack cloud-native, AI-assisted, and integrated (procure-to-pay → GL → reporting) or a patchwork of legacy tools?
Will you keep data ownership and real-time dashboard access?

3. Demand Modern Technology

Leading FaaS partners now embed artificial intelligence and machine learning to automate high-volume tasks—invoice capture, 3-way match, anomaly detection, rolling forecasts—while surfacing insights your team can act on. Look for:

  • True cloud architecture (no VPN-bound desktops).
  • Open APIs to integrate CRM, HRIS, and BI tools.
  • AI-driven quality controls that flag coding mistakes before they hit the ledger.
  • Self-service dashboards for executives and investors who want answers in minutes, not a month-end packet.

4. Confirm Cultural and Communication Fit

A finance partner becomes an extension of your management team. Validate that they:

  • Align cadence with your staff.
  • Provide a named engagement manager and clear escalation path.
  • Offer governance calls and board-ready packets on a predictable schedule.
  • Share your values around transparency, continuous improvement, and data security.

5. Check Reputation and Proof Points

Ask for client references in businesses similar to yours, then probe:

Delivery against SLA
Were closes faster and cleaner?
Depth of insight
Did FP&A models actually shape decisions?
Scalability
Could the provider flex resources up (or down) during funding rounds, acquisitions, or seasonal peaks?

Verified case studies and audit letters speak louder than slide decks.

Is FaaS Right for You?

FaaS is not a one-size-fits-all answer. The model delivers its greatest value and the fastest time-to-insight when your operating profile matches the strengths of a cloud-first, platform-enabled service.

FaaS Works Best When… FaaS May Not Be Ideal When…
Industry Alignment
  • B2B Software/SaaS
  • Professional Services & agencies
  • Digital Marketplace / eCommerce platforms
  • Health-tech & multi-site healthcare services
  • Investment-management firms (fund-level & management-company books)
  • Mission-driven non-profits seeking enterprise processes
Your industry depends on an industry-specific ERP/GL (e.g., construction, property-management, large-scale manufacturing) that cannot be migrated or integrated efficiently.
Team Structure & Needs
Lean Finance Teams need seasoned controllers, FP&A analysts, and CFO-level guidance without hiring a dozen people. You must maintain a unique fiscal calendar (4-4-5, 13-period, etc.) or statutory chart of accounts that overrides U.S. GAAP/IFRS conventions.
Operational Complexity
Multi-entity / multi-location structures demand consolidated, audit-ready reporting and best-practice KPIs. Operations require specialized government-contracting compliance (e.g., DCAA cost-accounting standards) that a horizontal platform cannot support.
Transaction & Data Management
Transaction volumes are high but transaction types are repeatable (subscriptions, time-and-materials, services, marketplace payouts) and can be automated with AI. You manage a high volume of physical-goods inventory with complex forecasting, bills of materials, or warehouse management that must reside inside the GL.
Reporting & Analytics
Leaders value real-time dashboards and rolling forecasts to make data-driven decisions. Most A/R, A/P, or management reporting must be handled in a foreign language or the company is headquartered entirely outside North America, creating regulatory or linguistic barriers a U.S.-centric platform won’t cover.

Why this matters: Focusing on core-competency industries lets a FaaS partner bring pre-configured process maps, benchmark KPIs, and talent with vertical expertise. Conversely, edge-case requirements, such as bespoke ERPs, heavy inventory, or niche compliance, can erode the time-to-value that makes FaaS attractive.

Consero in Action

Here are a few real-world examples of how a full FaaS engagement actually plays out:

Professional-services roll-up gets enterprise-ready
A Salesforce commerce agency completed an ERP upgrade in 90 days, integrated two acquisitions and executed three cash-to-accrual transitions within a year, trimming $85-$120K from first-year finance costs.
90-day SaaS finance transformation
Consero rebuilt the finance stack for this EHR/RCM vendor in three months, delivering GAAP revenue recognition and board-grade dashboards while cutting F&A spend 44-59 % ($342-432K over two years).
Non-profit spins up a $180M fiscal department in 30 days
During the transition from contractor to nonprofit, Consero’s BTQ division assumed full CFO responsibility, implemented end-to-end systems, and produced clean audits—allowing a lean two-person internal team to stay mission-focused.
Three roll-ups integrated for a premium exit
Preparing for sale, this insurance-software provider unified three acquisitions and reached audit-ready status in 90 days, all while lowering finance costs 37%—contributing to a successful sale to GI Partners.

More Than A Provider, A Strategic Partner

Selecting a Finance as a Service partner is less about low-cost labor and more about strategic enablement. Vet providers for expert people, battle-tested processes, and enterprise-grade platforms that deliver speed, accuracy, and insight. 

Consero checks every box while adding modular flexibility and high-octane advisory services that evolve as you do.
