The best offshore staffing providers for UK accounting firms in 2027 are the ones that give you dedicated, UK-trained staff, a signed International Data Transfer Agreement (IDTA), and clear quality control, not just the lowest hourly rate.
Leading names include MYCPE ONE, QX Accounting Services, Outbooks, AdvanceTrack, Corient, and AcoBloom. The right choice depends on your firm size, the work you want to move offshore, and how much control you need over the team.
This guide compares the leading offshore staffing providers for UK firms, explains the three main delivery models, and gives you a 10-point checklist to shortlist a partner with confidence.
Capacity is the real driver. According to Advancetrack's 2026 Accounting Talent Index, a survey of 500 firms across the UK, US, Canada, and Australia, 73% of accountancy firms are turning away potential clients because they lack the staff to deliver the work. Offshore staffing has moved from a cost experiment to a core resourcing strategy.
The best offshore staffing providers for UK accounting firms in 2027 are MYCPE ONE (dedicated, multi-role offshore teams), QX Accounting Services (high-volume, process-led work), Outbooks (smaller practices wanting a London contact), AdvanceTrack (a choice of outsourcing or offshoring), Corient (faster routine turnaround), and AcoBloom (hybrid co-sourcing).
Below are six offshore staffing providers for UK firms that actively serve accountancy practices, from London to regional firms across England, Scotland, and Wales. Each has a different strength, so match the provider to your priorities rather than reading this as a ranking of quality.
| Provider | Delivery model | Core services | Delivery locations | Best for |
|---|---|---|---|---|
| MYCPE ONE | Dedicated offshore staff | Bookkeeping, accounts prep, tax, audit support, payroll and virtual CFO. | India, Philippines | Long-term teams across multiple roles |
| QX Accounting Services | Offshore, onshore, hybrid | Bookkeeping, year-end accounts, tax, payroll, audit support | India, UK | High-volume, process-led work |
| Outbooks | Task-based outsourcing | Bookkeeping, VAT, payroll, year-end and management accounts | India (London HQ) | Small to mid-sized practices |
| AdvanceTrack | Outsourcing and offshoring | Bookkeeping, accounts preparation, tax | India, UK | Firms wanting both options |
| Corient | Outsourced accounting | Virtual accounting support for practices and finance teams | India | Faster routine turnaround |
| AcoBloom | Co-sourcing | Co-sourced accounting staff embedded in your team | India | Hybrid, integrated teams |
MYCPE ONE provides dedicated offshore staff to accounting firms across the UK, US, and Canada, covering bookkeeping, accounts preparation, tax, audit support, and payroll. Its offshore staffing also extends beyond accounting into admin, marketing, IT, and HR roles, which helps firms that want one partner for several functions.
Engagement terms are also built for CPA firms: a two-week free look-in, staff replacement option, no long-term contract, two-month exit notice, and no hidden fees.
Operating for more than 20 years, QX Accounting Services supports UK accountancy practices with bookkeeping, year-end accounts, tax, payroll, and audit support. Firms can choose offshore, onshore, nearshore, or hybrid delivery. It sits within QX Global Group, which has a workforce of over 3,000 across six global centres.
Headquartered in London with delivery teams in India, Outbooks is built around UK practices. Its services span bookkeeping, VAT returns, payroll, year-end accounts, and management accounts, with staff working across Xero, QuickBooks, and Sage.
AdvanceTrack has supported accountancy practices for many years with bookkeeping, accounts preparation, and tax work, and lets firms pick either an outsourced service or a dedicated offshore team. It is also behind the annual Accounting Talent Index, a widely quoted study of the accountancy skills shortage.
Corient provides virtual accounting support to accounting practices and in-house finance teams. Its offer centres on shorter turnaround times and lower operating costs for routine, repeatable work.
Set up by former Big 4 accountants, AcoBloom specialises in co-sourcing. Its offshore staff are positioned to work as part of your in-house team, not as a separate outsourced unit.
Offshore staffing is a resourcing model where a UK accountancy practice hires qualified accountants, bookkeepers, or tax preparers who work from another country, usually India or the Philippines, through a specialist provider.
The provider handles recruitment, payroll, office infrastructure, IT security, and HR. Your firm directs the day-to-day work. International providers often describe these clients as UK CPA firms, so you will see offshore staffing providers for UK CPA firms and UK accountancy practices used interchangeably.
It differs from traditional accounting outsourcing in one important way. With outsourcing, you send a job out and get a finished file back. With offshore staffing, the person becomes part of your team, works in your software, follows your checklists, and joins your team calls.
UK practices commonly offshore bookkeeping, VAT returns, year-end accounts preparation, self assessment and corporation tax return prep, payroll, management accounts, and audit support work.
Three pressures are pushing practices towards offshore staffing providers for UK accountancy work in 2027.
The same Advancetrack research found that 71% of firms say recruitment problems have slowed their growth, and 45% believe the shortage has worsened since 2023. Hays' UK Salary and Recruiting Trends 2026 reported that 93% of employers had faced skills shortages in the previous year.
Making Tax Digital for Income Tax, FRS 102 revisions, and incoming tax adviser registration requirements all add volume to already stretched teams. Quarterly MTD submissions alone turn a once-a-year self assessment client into a recurring workflow.
Clients resist fee rises on compliance, while UK salaries and employer costs keep climbing. Moving process-heavy work offshore frees UK staff for advisory work that clients will pay more for.
London practices feel the talent shortage hardest because they compete with Big 4, mid-tier, and in-house finance teams for the same people, at the highest salary levels in the country. That makes offshore staffing providers for London firms especially valuable for compliance-heavy work.
Three points matter most for London firms:
Most offshore staffing services fall into three models. Choosing the model first narrows your provider list quickly.
| Factor | Dedicated offshore staff | Task-based outsourcing | Hybrid co-sourcing |
|---|---|---|---|
| How it works | Full-time staff work only for your firm | You send jobs, provider returns finished work | Mix of dedicated staff and on-demand capacity |
| Control | High: you manage daily work | Low: provider manages process | Medium to high |
| Pricing basis | Monthly fee per FTE | Per job, per hour, or per return | Monthly base plus variable volume |
| Best for | Steady year-round workload | Seasonal peaks, e.g. January | Growing firms with uneven demand |
| Knowledge retention | Strong, same people build firm knowledge | Weaker, work may rotate across staff | Moderate to strong |
| Typical onboarding | 2 to 6 weeks | 1 to 2 weeks | 3 to 6 weeks |
Rule of thumb: if you have at least one full role's worth of work every month, a dedicated offshore staffing agency model usually gives better quality and lower long-term cost. If your work is mostly seasonal, task-based outsourcing avoids paying for idle time.
Cost depends on role seniority, location, and model. Dedicated staff are usually priced as a monthly fee per full-time employee, while task-based work is priced per job or per hour. Provider-published figures commonly cite savings of 30% to 40% against equivalent in-house costs, though your actual saving depends on how well the work is scoped and reviewed.
When comparing quotes, check what the fee includes:

Offshoring does not move your regulatory obligations. Your firm remains responsible for client data, AML, and the quality of every file that leaves the practice.
Sending client data to staff in India or the Philippines is a restricted transfer under UK GDPR. Neither country has UK adequacy regulations, so you need an appropriate safeguard, typically the ICO's International Data Transfer Agreement (IDTA) or the UK Addendum to the EU Standard Contractual Clauses, plus a transfer risk assessment.
The Data (Use and Access) Act 2025 changed the test for that assessment. Protection overseas must now be "not materially lower" than under UK GDPR, replacing the older "essentially equivalent" standard. The ICO published updated international transfer guidance in January 2026.
Under the Money Laundering Regulations 2017, customer due diligence and suspicious activity reporting stay with your firm and your Money Laundering Reporting Officer. Offshore staff can help collect and organise documents, but decisions and reporting must remain in the UK.
ICAEW, ACCA, and AAT members must protect client confidentiality and keep adequate oversight of outsourced work. Check your professional body's current guidance on informing clients that work may be processed overseas, and update your engagement letters and privacy notice to match.

Choosing between offshore staffing providers for UK accounting firms is no longer about whether to offshore, but how to do it safely and profitably. Start by deciding which model suits your workload, then shortlist providers on UK experience, data protection, and quality control, not price alone.
Pilot one role, measure the results, and scale what works. Firms that treat offshore staff as part of the team, and keep compliance firmly in the UK, are the ones turning the talent shortage into a growth advantage.

Leading offshore staffing providers for UK accounting firms in 2027 include MYCPE ONE, QX Accounting Services, Outbooks, AdvanceTrack, Corient, and AcoBloom. The best fit depends on whether you need dedicated staff, task-based support, or a hybrid model.
Offshore staffing gives you dedicated team members who work in your systems under your direction. Accounting outsourcing means sending tasks to a provider that manages the process and returns completed work. Staffing gives more control; outsourcing gives more flexibility.
Yes. UK firms can offshore accounting work if they meet UK GDPR international transfer rules, typically by using an IDTA or UK Addendum with a transfer risk assessment, and keep oversight of AML and professional obligations.

Provider-published figures commonly cite savings of 30% to 40% compared with in-house staff. Actual savings depend on role seniority, the delivery model, and how much review time the work needs.
Common tasks include bookkeeping, bank reconciliations, VAT returns, year-end accounts preparation, self assessment and corporation tax return preparation, payroll, management accounts, and audit support. See our list of 20+ roles UK firms can offshore.
You should be transparent. Update your privacy notice and engagement letters to explain that data may be processed outside the UK, and check your professional body's guidance on client disclosure.
Yes. Most offshore staffing providers for UK firms serve London practices, and some, such as Outbooks, have a London head office. London firms should prioritise India-based teams for time zone overlap and ask for written turnaround service levels.
Most dedicated staffing arrangements take 2 to 6 weeks from agreement to the first productive day. Task-based outsourcing can start within 1 to 2 weeks once workflows and access are agreed.
