How to Switch EOR Provider

Your CFO wants the global employment line cut by 18% before the next board meeting. Your incumbent EOR’s renewal lands in seven weeks at a 9% price hike. A competitor has quoted 22% less for the same eight countries.

The maths looks obvious until you sit with the operations team and realise that switching an EOR is not the same as switching payroll software.

Twelve real people in seven countries have to be terminated by one legal employer and re-hired by another, with health insurance, pension contributions, paid leave balances, and tax registrations all crossing a live boundary. Get it wrong and a cost-saving project becomes the reason a senior engineer in Berlin resigns or a payroll run misses statutory deadlines in Brazil. A botched switch costs more in attrition and legal exposure than the saving it was meant to deliver.

Why switching EOR providers is more complex than changing payroll software

When you change payroll software, the employer of record does not change. Employment contracts stay intact. Tax IDs, pension scheme memberships, and health insurance enrolments persist.

You are moving data and process, not people.

An EOR switch is structurally different. The employer of record is the legal entity that holds the employment contract, files payroll taxes, and carries the legal liability for the worker. When you change EOR provider, you change the legal employer.

The old contract must be terminated and a new contract signed with a different legal entity.

That single fact triggers most of the complexity. Termination triggers severance calculations in most jurisdictions. Re-hiring triggers a new probation period unless contractually waived.

Pension scheme memberships do not always port. Private health insurance policies are tied to the employer, not the worker, so there is a real risk of a coverage gap on the day of transition. Statutory paid leave balances may or may not transfer cleanly depending on how the new contract is drafted.

The practical implication: a switch that looks like a procurement decision is actually a coordinated employment-law event in every country involved.

The most common reasons companies switch EOR providers

Most switches fall into four categories:

• Cost. Switches typically involve 15% to 30% per-seat reduction. Below 15%, the saving rarely justifies the operational risk. If your renewal is up 9% and a credible competitor is 22% cheaper for the same scope, the three-year saving on 20 seats at $600 per month is roughly $95,000: your transition friction budget.
• Country coverage. The incumbent cannot support a new market without routing through a third-party partner at a 40% premium. A vendor with direct entities in those countries often becomes the reason to move the entire book.
• Service quality. Tickets sitting open for 11 days. Payroll calendars arriving 48 hours before cut-off. The CSM changed three times in 18 months. The People Ops lead spending six hours a week chasing the EOR is a cost that does not appear on any quote.
• Acquisition or strategic concern. The incumbent has been acquired by a parent you do not trust on data residency or pricing stability. These switches tend to be slower and more deliberate.

How the employment transfer actually works: terminate and rehire, not transfer

There is no such thing as transferring an employee from EOR-A to EOR-B. The mechanism is always: EOR-A terminates the employment contract on a specific date. EOR-B issues a new contract effective the same date or the day after.

The worker signs both documents, plus an acknowledgement that this is a coordinated transition rather than a redundancy.

• Notice period: EOR-A’s contract usually requires statutory or contractual notice. In Germany at least four weeks to the 15th or end of the month; in the UK one week per year of service up to 12 weeks. Notice can be waived by mutual agreement but the worker has to consent in writing.
• Final payroll from EOR-A: salary up to termination date, accrued unused holiday, any 13th-month proration owed, and any triggered severance.
• New contract from EOR-B: matches the existing salary, benefits, job title, and start date as closely as possible. Should explicitly recognise prior service for statutory purposes where local law allows.
• Benefits re-enrolment: health insurance and supplementary benefits are re-enrolled under EOR-B’s plan. The two plans are rarely identical.
• Pension and social security: employer contributions stop with EOR-A and start with EOR-B. Accrued pension rights typically stay with the scheme administrator.

The four operational risks in an EOR switch

Risk 1: Benefits coverage gap

Private health insurance under EOR-A ends on the termination date. EOR-B’s policy starts on the new contract effective date. If those dates do not align, the worker is uninsured for the gap.

In the US, Singapore, or the UAE this means out-of-pocket costs and potential pre-existing condition exclusions. Fix: align dates exactly, get written confirmation from both vendors that coverage is continuous, and run a 14-day post-transition check.

Risk 2: Payroll timing gap

If EOR-A runs on the 25th and EOR-B on the 28th, the worker sees two smaller deposits instead of one regular salary. Time the transition to a clean payroll cycle boundary, typically the first of the month, so EOR-A pays the full preceding month and EOR-B the full following month.

Risk 3: Statutory leave balance loss

EOR-A pays out accrued leave as part of final salary. EOR-B starts the accrual at zero. The worker receives the money but loses the time.

Negotiate with EOR-B on whether they will credit prior accrual as a one-off goodwill balance. Most will not without a contractual incentive.

Risk 4: Tax registration gap

Re-registering with EOR-B can take 5 to 20 working days depending on jurisdiction. During the gap, withholding cannot be filed correctly. Brazil, India, and Mexico are particularly exposed.

Confirm in writing that EOR-B is registered and ready to file before the transition date.

The switching timeline: what a well-managed transition looks like

A clean EOR switch for 10 to 30 employees across three to five countries takes 6 to 8 weeks from contract signature to fully migrated state. Compressing below 4 weeks is possible only if the incumbent waives notice and the new vendor has standing entities in every country.

• Weeks 1 to 2: Sign the MSA with EOR-B. Confirm local entity, registration status, and earliest start date per country. Review contract templates with employment counsel. Notify EOR-A of intent to terminate.
• Weeks 3 to 4: Communicate to affected employees: role, salary, and reporting line unchanged. Have answers about pension, health, and accrued leave ready before the announcement. Issue new EOR-B contracts aligned to a clean payroll cycle boundary.
• Weeks 5 to 6: Workers sign EOR-A termination acknowledgement and EOR-B new contract. EOR-B begins onboarding: bank details, tax ID, pension nomination, benefits enrolment. Both vendors confirm transition date in writing.
• Weeks 7 to 8: Final payroll from EOR-A. First payroll from EOR-B. Verify benefits cards and logins with each worker. EOR-A deposit released 30 to 60 days after last employee leaves their books. Reconcile invoices.

The deposit problem: cash flow during a switch

Almost every EOR holds a security deposit of one or two months of payroll plus statutory contributions. For a 20-seat book at $7,000 fully loaded per worker, that deposit is $140,000 to $280,000. During a switch, two deposits are in play: EOR-B requires theirs 10 to 20 working days before the transition date; EOR-A returns theirs 30 to 60 days after the last worker leaves.

For the example above, $280,000 to $560,000 is tied up for 40 to 80 days.

Negotiate with EOR-B for a deposit phased over two months. Confirm with EOR-A the exact release date in writing. Some EORs accept a parent-company guarantee or letter of credit instead of cash, which is cheaper than the opportunity cost of cash sitting on the EOR’s balance sheet.

How to maintain continuity for employees during the switch

Affected employees should hear from their manager or People Ops lead, not from a sudden contract email from a vendor they have never heard of. Cover the why (cost, coverage, service), the what (salary, role, benefits unchanged), and the when (transition date, what to sign, by when).

Health insurance under EOR-B will not be identical to EOR-A. Produce a one-page benefits comparison and share it with each affected worker. Where the new benefit is materially worse, decide in advance whether the company will top up the difference.

Discovering this in week 6 instead of week 2 is the most common cause of last-minute attrition.

Paid leave balances, redundancy service length, and equity vesting tied to continuous employment all need explicit treatment in the new contract. The default is that none carry over. Run a 30-day post-transition check with each worker to confirm salary, benefits cards, pension, and expenses all landed correctly.

Issues caught at 30 days are recoverable; issues caught at 90 days are usually formal complaints.

Negotiating exit terms with your outgoing EOR

The incumbent holds the deposit, controls final payroll timing, signs off on termination paperwork the new vendor needs, and owns the relationship with the local tax authority. A professional EOR will cooperate. The conversation to have with the incumbent CSM is direct: the company is moving, the timeline is fixed, here is what we need.

Key points to get in writing:

• Notice compression: Ask to reduce 60 or 90 day notice to 30 or 45 days in exchange for a clean handover commitment.
• Deposit release date: A specific date tied to the last payroll completion, not a vague 30 to 60 day window.
• Final invoice scope: Which fees are owed for the partial final month. Pro-rated platform fees are negotiable; statutory contributions are not.
• Data return format: All employee records, payroll history, tax filings, and benefits data in a structured format.

Frequently asked questions

Can an EOR refuse to release my employees to a competitor?

No. The worker can resign and join a new employer at any time, subject to notice. The client company can terminate the master service agreement subject to its notice terms. A professional EOR will cooperate with the transition.

How long does an EOR switch usually take?

Six to eight weeks for a well-managed transition covering 10 to 30 employees in three to five countries. Compress below four weeks only if the incumbent waives notice and the new vendor has standing entities in every country.

Will my employees lose their accrued holiday when we switch?

The accrued balance is paid out as cash by the outgoing EOR. The new EOR usually starts the accrual at zero unless you negotiate explicit recognition. Workers receive the money but lose the time, which can disrupt planned holidays.

Do I have to pay severance when switching EOR providers?

In most jurisdictions, statutory severance is triggered by termination regardless of reason. A coordinated transition where the worker is immediately re-hired can reduce or waive severance in some countries, but this requires local-law advice and the worker’s written consent. Budget for full severance unless you have written confirmation otherwise.

Can we switch only some employees?

Yes. Running two EORs in parallel adds overhead but is workable for 6 to 18 months while a full migration is planned.

What is the typical cost of switching EORs?

Direct costs: legal review of country-specific contracts (1,500 to 4,000 GBP per country) and any benefit top-ups. Indirect costs: deposit overlap tying up 200,000 to 500,000 USD for 40 to 80 days, plus 40 to 80 hours of People Ops time. Budget 15,000 to 40,000 GBP for a 20-seat book, in addition to the deposit cash flow impact.
