Finance and accounting outsourcing is the use of an external team to perform defined finance and accounting functions on behalf of a business or accounting firm.
GSC provides that team: finance specialists who plug into your existing systems and processes, so the work keeps moving without you hiring, training and managing every extra role yourself.
We work with accounting firms that need more capacity to deliver for their own clients and with growing businesses that need their finance function run reliably: across the industries we serve.
Extend
Add finance capacity when your existing team is stretched.
Integrate
Work inside the systems, processes and workflows you already use.
Scale
Take on more work without adding headcount.
Six services. One dedicated team.
Start with one or combine several. The same team runs them.

GSC offers two engagement models. With Outsourcing, our team runs a defined function end-to-end. With Offshore Staffing, dedicated professionals join your operation and work under your direction. Neither model is better. The right one depends on how you want to work. Both come with dedicated people, defined deliverables and a team you can actually reach. Many businesses start by outsourcing one function, then grow it into a dedicated team we build around them.
Hand off the entire function.
Give us a defined finance or accounting function and our team runs it end-to-end, inside your systems and on your reporting calendar.
- Defined SLAs and weekly reporting
- One accountable team across the whole workflow
- Built for firms that want a function fully off their plate
Build your own dedicated team.
Add dedicated finance professionals to your operation while you keep control of the workflow, the client relationship and the systems.
- You direct the day-to-day work

A fantastic partner
I’ve been working with GSC Outsourcing for over a year now through KW Accounting Solutions … They’ve handled sensitive information with integrity and have always followed through on what they promised.
Thank you GSC
We have built a large bookkeeping and CFO organization with the help of GSC and consider them a key partner.
Exactly the accounting partner we needed
They stepped in immediately and went far beyond my expectations. … Today, they fully handle our accounting (for multiple companies) as if it were their own department.
These guys are amazing
I have worked with multiple consultants and advisors but no one beats the trio of Gautam, Charu and Divya. … I found the team at GSC Outsourcing to be more caring for the client, they met timelines and they offered excellent after service support.

Straight answers to what every CFO, founder and firm partner asks.
What is GSC Outsourcing?
GSC Outsourcing provides AI-augmented finance and accounting outsourcing and builds dedicated finance teams for businesses and accounting firms. Founded in 2020, our teams work inside your existing systems and processes, pairing experienced finance professionals with AI-assisted workflows across Client Accounting Services, US Tax Compliance, CFO & Financial Planning, Audit Support and Accounting Advisory so the numbers keep moving without your team carrying it all.
What services does GSC provide?
We provide six core services: Client Accounting Services (bookkeeping, AP/AR, month-end close and reporting), US Tax Compliance, CFO & Financial Planning (budgeting, forecasting and financial modeling), Audit Support (workpapers and reconciliations), Accounting Advisory (ERP support, technical accounting and SOP creation) and Real Estate Analysis & Underwriting (deal underwriting, asset management reporting and property accounting). You can start with one function or several.
Who does GSC work with?
GSC works with accounting firms that need more capacity to deliver for their own clients and with growing businesses that need a dependable finance function. Clients span professional services, technology and SaaS, real estate, financial services, healthcare, nonprofit and other growing businesses.
What does finance and accounting outsourcing include?
The day-to-day work that keeps your books current and your close on track: bookkeeping, AP and AR, reconciliations, payroll processing and reporting. Plus tax support, audit prep and CFO-level analysis when you need it. You define the scope and we staff it.
What is the difference between outsourcing and offshore staffing?
With outsourcing, our team runs a defined function end-to-end within your systems and reporting cadence. With offshore staffing, you get dedicated professionals working inside your operation while you keep control of the workflow and client relationship.
Will we have dedicated people working with us?
Yes. You get dedicated people who know your business, not a rotating queue. You'll always know who's working on what and who's accountable for it.
Can your team work inside our existing accounting systems?
Yes, we work inside QuickBooks, Xero, NetSuite, Sage or whatever you already run. We don't ask you to migrate systems just to work with us.
How do you use AI in your accounting workflows?
AI handles repeatable work (data entry, reconciliations, first-pass categorization) so our team can focus on review, exceptions and judgment calls. Every output is reviewed by a person before it reaches you.
How do you protect financial and client data?
Every engagement runs under ISO 27001 and GDPR controls, with role-based access and logging. Any AI-assisted workflow anonymizes data first and is reviewed by a person before delivery.
How long does onboarding typically take?
Most engagements move from signed agreement to first live delivery in about two weeks, depending on how much knowledge transfer your systems need.
Can we start with only one part of our finance function?
Yes. You can start with a single workflow (like the close or AP) and add more whenever you're ready.
How we protect your financial data.
Your books hold payroll, margins and your clients’ details. Access to them is earned, limited and logged.
GSC runs every engagement under ISO 27001 and GDPR controls with role-based access and logging. Client data is anonymized before any AI workflow touches it and every output is reviewed by a person before delivery.
