# FinOps Hub

> Embed invoicing, bill pay, payments, and expense management into your platform with FinOps Hub. Modular financial workflows for banks, marketplaces, and SaaS providers.

FinOps Hub gives banks, marketplaces, and SaaS platforms the infrastructure to become the financial operating system for their business clients — without building it themselves.

Through a single integration, your platform can offer the full suite of financial workflows that business customers actually run on: invoicing and collections ([accounts receivable](/finops/guides/accounts-receivable/index)), bill payment and approval automation ([accounts payable](/finops/guides/accounts-payable/index)), payments, AI-powered [expense management](/finops/guides/expense-management/index) and more. Each capability is modular — embed what your clients need today, and expand as your offering grows.

FinOps Hub offers flexible integration options — drop-in widgets for fast deployment, a white-label platform with SSO, and direct APIs for fully custom builds. Payments are equally flexible: move money through Tesouro's own [acquiring](/acquiring/index) solution, or connect to the leading payment processors across the US — whichever fits your existing stack.

Not sure where to start? [Talk to our team](/finops/support) — we'll help you find the right integration for your business.

## How FinOps Hub works

FinOps Hub is a SaaS (Software as a Service) that your backend securely sends and retrieves financial data to and from its server using a series of [REST](https://en.wikipedia.org/wiki/Representational_state_transfer) calls.

Built on a microservice architecture, each API endpoint is its own secure service built with full redundancy and failover.
