What Do Professional Audit Support Services Include?
Professional audit support services include planning assistance, workpaper preparation, substantive testing, lead schedules, tie-outs, confirmations and review-note clearance. A trained offshore team completes this execution work inside your firm’s methodology, while partners keep control of judgement, sign-off and client contact. For CPA firms stretched thin during busy seasons, this model adds capacity without permanent hires. It lowers the risk of missed deadlines when two engagements land in the same week.
What Is Included in Audit Support Services?
Most providers cover the execution layer of an audit engagement. This is the detailed, time-heavy work that sits between planning and partner review. A capable team typically handles:
- Audit planning documentation and risk assessment files
- Workpaper preparation in your firm’s templates
- Substantive testing and sample selection
- Lead schedules, tie-outs and roll-forwards
- Trial balance mapping to financial statements
- Confirmation tracking and review-note clearance
How Do Audit Preparation Services Differ from Fieldwork Support?
Preparation work focuses on readiness before fieldwork begins. The team cleans up the trial balance, reconciles key accounts, organises the PBC (provided by client) list and builds lead schedules. Fieldwork support starts later and covers testing, sampling and documentation. Firms that book both together usually see fewer surprises, because the preparers already know the file when testing starts. That continuity saves hours of rework in the final week.
Why Do CPA Firms Choose Outsourced Audit Support?
Firms look offshore because the staffing gap is real, and it wears teams down. Experienced seniors are hard to recruit, and the busy season stretches small practices until quality slips. An offshore team providing audit support services absorbs the volume of preparation and testing work. Partners and managers then spend their hours on judgement areas, client conversations and final review, where their experience counts most.
Peak Season Capacity Without New Hires
Calendar year-end audits pile up between January and April. A flexible offshore team scales up for those months and scales down afterwards, so the firm stops paying for idle capacity. Firms that add audit preparation services in December also start January with cleaner files.
Better Use of Senior Staff
When assistants handle tie-outs and roll-forwards, seniors move into review and coaching. They stop chasing small reconciling differences and spend more time on risk areas. Morale improves as well, since fewer people burn out on repetitive tasks late at night.

How Does Scan Global Services Support CPA Audit Teams?
The firm provides dedicated offshore audit managers, senior audit assistants and audit assistants to U.S. CPA firms, including at short notice. It draws on the heritage of SCAN Group, a chartered accountancy practice established in 1955, and its teams train in U.S. GAAP and GAAS. We prepare review-ready workpapers, while your firm keeps full control of audit decisions, sign-off and client communication.
Work That Fits Your Methodology
The team works inside your templates, tools and timelines. It already uses CaseWare, CCH, QuickBooks and Xero, and every file passes internal quality checks before submission. One mid-sized CPA firm’s audit manager credited the team with carrying them through peak season without extra headcount.
Security, Access and Communication
Scan Global Services protects client data through controlled access, secure file sharing and signed NDAs. Each firm gets a dedicated team with a single point of contact, and working hours overlap with the U.S. business day. Every outsourced audit support engagement begins with a free consultation, followed by scoping, team selection and onboarding.
Frequently Asked Questions
How much does offshore audit assistance cost?
Cost depends on the roles you need, the number of engagements and the length of the season. Providers typically quote engagement-based or monthly fees. Offshore support usually costs less than an equivalent local hire and avoids salaries, benefits and long-term payroll commitments.
Is it safe to share client files with an offshore audit team?
Yes, provided the team follows clear security controls. Look for role-based system access, secure file-sharing platforms, signed NDAs and written confidentiality policies. You should also confirm who can view client data, where files sit and how access ends after the engagement closes.
Who signs the audit report when part of the work is outsourced?
Your CPA firm signs the report and keeps full responsibility for the opinion. The offshore team prepares documentation and performs assigned procedures under your supervision. Partners and managers review the work, make the judgement calls and handle all communication with the audited client.
How long does it take to onboard an offshore audit team?
Onboarding time depends on scope and the roles involved. The usual sequence covers a needs assessment, candidate screening, joint selection, system access and a walkthrough of your templates. Starting before a busy season lets the team learn your methodology on a smaller engagement first.
