Why Marketplace eCommerce Needs Finance As A Service (FaaS)

The rapidly growing eCommerce sector needs an innovative and robust solution for building and scaling the finance function.
Updated: May 16, 2025

Global marketplace eCommerce sales are estimated to exceed $8 trillion by 2028, driven by border-free shopping, social-commerce adoption, and the rise of Gen AI–powered product discovery. Yet most founders still rely on the same manual spreadsheets they used at launch.

As order volume, SKUs, and cross-border tax rules multiply, or investors enter the picture, growing eCommerce companies often find their in-house finance systems overstretched and inefficient to manage scaling complexity. 

There’s a way for eCommerce businesses to get enterprise-grade finance without building a costly in-house department.

Consero’s Finance as a Service (FaaS) offers a proven, cloud-based playbook that simplifies financial management, providing robust tools and expert teams tailored specifically for investor-backed eCommerce companies.

The Risks When Scaling Finance Functions in eCommerce

Scaling eCommerce businesses often face common financial management risks:

1 Inadequate Integration of Financial Technology

Fragmented financial systems lead to slow, manual reconciliation.
Errors and inaccuracies arise, creating compliance risks.
Lack of real-time insights on profitability, cash flow, and spend.

2 Poor Visibility of Contract Terms

Limited visibility into payment terms and obligations.
Increased risk of cash flow mismanagement and late payment penalties.

3 Difficulty Correlating Revenue and Spend

Disconnected sales, marketing, inventory, and accounting systems complicate spend analysis.
Inefficient tracking impacts strategic decisions and profitability.

4 Scaling Overhead Ineffectively

Misalignment in staffing and resource allocation during peak periods.
Excessive costs or understaffing leads to missed opportunities and penalties.

As marketplace brands hit these inflection-point risks, leadership has two paths:

One is the familiar route of incrementally building an in-house finance team—hiring controllers, FP&A analysts, systems talent and layering on new software. That approach offers direct control but can absorb months of recruiting bandwidth and significant capital, nudging focus away from growth initiatives.

The newer path is Finance as a Service (FaaS): a turnkey combination of seasoned professionals, standardized processes, and a pre-integrated tech stack that can be stood up quickly and scale with the business.
