To build an offshore team that actually works, a UK accounting firm should run a structured 90-day rollout. Days 1 to 30 cover onboarding and a parallel run on completed work. Days 31 to 60 move the team onto live, low-risk client work with daily review.
Days 61 to 90 build autonomy, cut review time and add a second role. The groundwork before day one (UK GDPR transfer paperwork, client notification and written processes) decides whether the plan succeeds.
Most UK practices are no longer asking whether to offshore. They are asking how to do it without disrupting client service or creating a compliance gap. This playbook answers that question week by week, with the checkpoints, owners and KPIs a practice owner or operations lead needs.
A 30/60/90-day offshore team playbook is a phased onboarding plan that moves new offshore accounting staff from training to independent production in about three months. Each 30-day phase has a defined scope of work, a named UK owner, and exit criteria that must be met before the team moves on.
The structure borrows from the 30-60-90 day onboarding plan used for in-house hires. The difference is that offshore onboarding also has to handle data transfer compliance, remote access, time zones and client communication, so the preparation phase matters more.
The pressure to offshore is real, and so is the risk of doing it badly.
Without a plan, firms tend to hand over too much too soon, skip the compliance paperwork, and judge the team on early errors that better onboarding would have prevented. A phased playbook avoids all three.
Before an offshore team starts, a UK firm should choose the first workflow, document it, sign the data transfer paperwork, tell clients, and set up secure system access. Allow two to four weeks for this. Firms that skip it usually lose the first month fixing gaps.
Pick one high-volume, rules-based workflow with clear inputs and a UK reviewer who has time to check work. Good first roles include:
Keep tax advisory, HMRC enquiries, unusual reliefs and audit judgement areas in the UK for now.
Anything your team does from memory will be done differently by someone new. Turn tacit know-how into documents before day one:
Sending client personal data outside the UK is a restricted transfer. India and the Philippines do not have UK adequacy regulations, so you need an International Data Transfer Agreement (IDTA) or the UK Addendum to the EU Standard Contractual Clauses, plus a transfer risk assessment. Your provider contract should also include Article 28 processor terms. Our UK GDPR security checklist for offshoring covers each document.
Update engagement letters and your privacy notice to say that work may be processed by staff outside the UK under contract and data protection safeguards. The ICAEW Code of Ethics treats client confidentiality as a fundamental principle, so clients should not discover offshoring by accident.
Appoint a manager or senior who is accountable for the rollout. They clear the query log each day, run the weekly review, and decide whether each phase gate has been passed. Split accountability is the fastest way to stall a new team.
The first 30 days are for learning your firm's way of working, not for clearing your backlog. The goal is an offshore team that can prepare a standard file to your checklist with predictable review points.
Give the team 15 to 25 files you have already completed and filed, such as last year's Self Assessment returns or closed VAT quarters. They prepare each one independently, and you compare their output with the filed version.
This tells you accuracy without any client risk. It also shows which parts of your process are undocumented, because those are where errors cluster.
Move to a small batch of live, low-complexity work. Every file gets a full UK review. Log each review point by type (technical error, process error, missing information) so patterns are visible.
Move to phase two only when:
In the second phase, the offshore team takes on a steady flow of live work in the first workflow while the UK owner tightens the review loop. The aim is consistency: the same file type, prepared the same way, with falling review time.
Raise the number of files gradually, but keep the file type the same. A team preparing 40 simple VAT returns well is more valuable at this stage than one preparing 10 complex ones badly.
Record three numbers for every file from day 31:
By day 61, the first workflow should run with light-touch review. This phase is about building autonomy, moving from full review to risk-based review, and deciding what to offshore next.
Once accuracy is stable, stop reviewing every line of every file. Review high-risk areas in full (for example capital gains, overseas income or unusual expenses) and sample the rest. Document the change so your quality management approach under ISQM (UK) 1 stays clear.
Extend the first role to slightly harder work: Self Assessment clients with property income, VAT clients on partial exemption, or accounts with more adjustments. Keep the review intensity higher for these new file types.
A second role is justified only when the first one meets its day-90 targets. Common second roles are:
Repeat the same 30/60/90 cycle for the new role. It usually runs faster because the security, access and communication setup already exists. See our list of 20+ accounting roles UK firms can offshore for options.
Run a formal review with the provider and your partners:
Each phase changes three things: the type of work, how much the UK reviews, and what must be true before moving on.
| Phase | Focus | Work Type | UK Review Level | Exit Criteria |
|---|---|---|---|---|
| Pre-launch (2 to 4 weeks) | Compliance and setup | None | Not applicable | IDTA, TRA, engagement letters, checklists and access in place |
| Days 1 to 30 | Learn the process | Parallel run on filed work, then a few live files | 100% of files, line by line | Parallel accuracy meets your bar; queries via log |
| Days 31 to 60 | Consistency | Live work, one file type, rising volume | 100% of files, falling time per file | Review points and review time falling week on week |
| Days 61 to 90 | Autonomy and scale | Moderate complexity; second role planned | Risk-based: high-risk areas in full, rest sampled | Day-90 targets met; scale decision made |
Set your own targets before day one based on your current in-house numbers. The table shows the direction a healthy team should move.
| KPI | How to Measure | Days 1 to 30 | Days 31 to 60 | Days 61 to 90 |
|---|---|---|---|---|
| Accuracy | Review points per file | Establish baseline | Falling weekly | Stable at target |
| Turnaround | Hours from receipt to ready for review | Not tracked | Within agreed SLA | Within SLA at higher volume |
| UK review time | Reviewer minutes per file | High (full review) | Falling | Below in-house prep plus review time |
| Query quality | Queries raised before vs after errors | Mostly reactive | Mostly proactive | Proactive, fewer repeats |
| Capacity released | UK hours freed per week | Negative (training cost) | Break-even | Positive and growing |
The UK firm keeps every client-facing decision, every HMRC submission and every professional sign-off. The offshore team owns preparation, data processing and first-level checks. Writing this split down before day one prevents most handover disputes.
| Activity | UK Firm | Offshore Team | Provider |
|---|---|---|---|
| Client relationship and engagement letters | Owns | None | None |
| Collecting records and chasing clients | Owns | Supports (missing-info lists) | None |
| Bookkeeping, reconciliations, data entry | Reviews | Owns | Supervises |
| Tax return and accounts preparation | Reviews and signs off | Prepares | Supervises |
| HMRC submissions and Government Gateway access | Owns | No access | None |
| Technical judgement and advisory | Owns | Flags issues | None |
| AML client due diligence and MLRO reporting | Owns | Flags red flags | None |
| Training on firm process | Leads | Attends | Supports |
| Staff hiring, payroll, retention, IT security | Approves | None | Owns |
| UK GDPR controller duties | Owns (controller) | Follows controls | Processor duties |
Five compliance areas apply to every UK firm building an offshore team: UK GDPR international transfers, client confidentiality, HMRC access, anti-money laundering, and quality management. Each one maps to a point in the 90-day plan.
| Area | What It Requires | When in the Playbook |
|---|---|---|
| UK GDPR international transfers | IDTA or UK Addendum, transfer risk assessment, Article 28 processor contract, updated privacy notice | Pre-launch |
| Client confidentiality | Disclosure in engagement letters; ICAEW, ACCA or AAT ethics duties on confidentiality | Pre-launch |
| HMRC access | No sharing of Government Gateway or Agent Services Account credentials; UK staff submit | Pre-launch, checked at day 90 |
| Anti-money laundering | Client due diligence and suspicious activity reporting stay with the UK firm under the Money Laundering Regulations 2017; offshore staff trained to flag red flags | Days 1 to 30 training |
| Quality management | Document review levels and changes under ISQM (UK) 1 for firms that apply it | Days 61 to 90, when review moves to risk-based |
The Data (Use and Access) Act 2025 amended the UK transfer test, but it did not remove the need for transfer safeguards. Check the current ICO guidance before you sign, and ask your provider for evidence such as ISO/IEC 27001 certification or Cyber Essentials Plus.
A UK accounting firm that wants to build an offshore team should treat it as a 90-day project, not a hire. Prepare the compliance and process groundwork first, start with one workflow, prove accuracy on work you have already filed, and scale only when review time is falling and the numbers support it.
The sequence matters more than the speed. A practice that spends 90 days earning trust in one role ends up with a team it can grow. A practice that rushes usually re-reviews everything, and the savings disappear into partner time.

Talk to our UK offshoring team about a 90-day rollout for your firm.
Most UK firms need about 90 days to move one offshore role from onboarding to steady, independent production, plus two to four weeks of preparation before day one. Each additional role usually takes less time because security, access and communication are already set up.
In the first 30 days, an offshore team should learn the firm's process, work through checklists and example files, and re-prepare 15 to 25 already-filed files in a parallel run. A few low-complexity live files can follow in week four, all fully reviewed in the UK.
The best first role is a high-volume, rules-based workflow such as bookkeeping, VAT return preparation, or straightforward Self Assessment returns. These have clear inputs and are easy to review. Keep advisory, HMRC enquiries and audit judgement work in the UK.
UK firms should tell clients in their engagement letters and privacy notice that work may be processed outside the UK under contract and data protection safeguards. UK GDPR requires transparency about international transfers, and professional ethics codes treat client confidentiality as a core duty.
UK firms need an International Data Transfer Agreement (IDTA) or the UK Addendum to the EU Standard Contractual Clauses, a transfer risk assessment, and an Article 28 processor contract. Neither India nor the Philippines has UK adequacy status.
No. Offshore staff should prepare returns, but submissions should be made by authorised UK staff. Firms should never share Government Gateway or Agent Services Account credentials with offshore team members.
Track three numbers on every file: review points per file, turnaround time, and UK review time per file. If review time falls steadily through days 31 to 90, the team is adding real capacity.
India is 4.5 hours ahead of the UK in summer and 5.5 hours in winter, giving a solid UK-morning overlap. The Philippines is 7 to 8 hours ahead, so overlap is shorter unless staff work shifted hours. See our India vs Philippines vs South Africa comparison.
