What we take off our clients’ plates.
From month-end closes that kept slipping to tax seasons that stretched the team, here’s the work we do and what clients say about it.
The work we do.
Every engagement is shaped around the client's own workload, tools and goals. These are the kinds of problems each service is built to help with.
Client Accounting Services
For teams closing the books too slowly or where bookkeeping, reconciliations, AP, AR and reporting are sitting with founders or finance leads who have other work to do. A dedicated team handles it inside your existing systems.
US Tax Compliance
For businesses and firms whose tax workload outgrows in-house capacity: business and individual returns, multi-state filings and sales tax, prepared and reviewed inside your existing process.
CFO & Financial Planning
For leadership teams that have financial data but not the time to turn it into decisions: budgeting, forecasting, cash-flow planning, financial modeling and KPI reporting.
Audit Support
For organizations where audit prep takes too long and pulls the team away from day-to-day work. We help prepare and organize workpapers, reconciliations and documentation; your independent auditor issues the opinion.
Accounting Advisory
For finance teams navigating change: ERP implementation support, technical accounting, SOP creation, chart-of-accounts redesign and accounting migrations.
Real Estate Analysis & Underwriting
For investors, lenders and developers with more deals than analyst hours: deal underwriting, T12 and rent roll reviews, custom models, asset management reporting and property-level accounting, built in your templates.
Who we work with.
Different industries, the same problem: more finance work than people to do it.

Project-heavy books, partner distributions and tight closes.
Technology & SaaS
Revenue recognition, metrics and investor-ready reporting.

Multi-entity books, property-level accounting and CAM reconciliations.

Other Growing Businesses
If the work is piling up faster than you can hire, we should talk.
In their words, not ours.
Behind every review is a business owner who once had too much on their plate and took a chance on us. They trusted us with their books, their deadlines and their own clients. These are their words on what that trust has grown into.
GSC Outsourcing has been an extraordinary extension of our internal team. Their level of precision, consistency and operational excellence has elevated the way we deliver bookkeeping, tax preparation and financial support projects to our clients.
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.
We have built a large bookkeeping and CFO organization with the help of GSC and consider them a key partner.
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.
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.
