How to Switch EOR Providers Without Disrupting Payroll

Why companies switch EOR providers

The most common reasons companies migrate to a new EOR provider are excessive costs (often 30–40% above market rate), slow or unresponsive support, compliance concerns, limited country coverage, and poor technology. Staying with an underperforming or overpriced provider costs more in the long run than the effort of switching.

The three phases of an EOR migration

Phase 1: Preparation (4–6 weeks before go-live)

• Select the new provider and negotiate terms — ensure the new contract start date aligns with your notice period to the current provider
• Review all current employee contracts — identify any terms that need to carry over to the new employment agreement
• Check your current provider's notice period — most require 30–90 days
• Confirm the new provider's entity setup and compliance readiness in each target country
• Communicate the change to employees — explain what is changing and what stays the same

Phase 2: Transition (2–4 weeks)

• New provider issues compliant employment contracts to each employee — employees sign new agreements before the transfer date
• Final payroll run with the current provider — confirm all accrued leave, expenses, and outstanding payments are processed
• New provider takes over payroll from the agreed transfer date — ideally at the start of a payroll cycle
• Employee benefits (pension, health insurance) are transferred or re-enrolled with the new provider
• IT access, expense systems, and HR tools are updated to reflect the new provider

Phase 3: Stabilisation (first 30 days)

• Confirm first payroll run with new provider is accurate — verify each employee's net pay against their previous payslip
• Resolve any discrepancies immediately — payroll errors in the first month erode employee confidence
• Obtain termination confirmation and final invoices from the previous provider
• Archive all employment records from the previous provider

What to watch out for

The most common migration problems are: overlapping payroll periods causing double payment, gaps in benefits coverage during the transition, and employees being left on the old provider's system after the agreed transfer date. All three are avoidable with proper scheduling and clear contractual handover terms.
