Mergers and acquisitions (M&A) bring exciting growth opportunities but also introduce operational complexities, especially when it comes to payroll integration.

This article contains insights from Deel’s recent Global Payroll Summit, where Dan Van Damme, Manager, Account Executive, ENT, Deel, spoke about how companies can use global payroll to streamline M&As. Watch the summit on-demand to hear from Dan and other experts.
Addressing challenges for smaller businesses
Smaller businesses often face resource limitations managing payroll in mergers and acquisitions. Budget constraints, fewer HR specialists, and reliance on outdated systems can amplify payroll challenges. Deel’s scalable platform provides:
- Affordable solutions: Ensuring smooth payroll implementation without overwhelming limited budgets
- Simplified onboarding: Streamlined processes for small teams to onboard employees seamlessly
- Expert support: Access to compliance specialists, even for businesses without dedicated HR teams
It’s often the case that mobility teams, compliance teams, payroll teams, and legal teams are very disjointed and disparate across an organization. The conversations we’ve been in typically involve, ‘How can you help us quickly onboard employees? This merger or acquisition is coming to a close in a matter of weeks, and we need to set up payroll fast.’ With Deel's owned infrastructure, we can quickly onboard payroll in a specific country in a matter of weeks, not months."

Managing compliance across borders
Compliance becomes critical when merging payroll systems, particularly in navigating tax regulations, benefits, and employment laws across jurisdictions. For instance, US. companies face EIN (Employer Identification Number) complexities that impact W-2 forms and tax filings. Missteps can lead to over/under-taxation and significant penalties.
Deel’s global payroll platform simplifies compliance by:
- Centralizing payroll management under one system
- Automating tax reporting and W-2 form management to prevent payroll errors
- Actively monitoring regulatory updates and providing actionable advice
Pro Tip: Use Deel’s compliance hub to stay ahead of local and international tax requirements during transitions.

Delays caused by external factors
External challenges, such as government updates or logistical issues, often cause delays in payroll integration. For example, global events like COVID-19 disrupted regulatory processes and payroll timelines. Deel mitigates such risks with:

- Built-in flexibility: Scalable solutions to adapt to unexpected delays
Harmonizing compensation and benefits
Aligning pay scales and benefits is critical for retaining employees and avoiding pay inequities. Deel’s solutions ensure:
- Compensation transparency: Align pay scales to prevent discrepancies
- Localized benefits: Tools to match statutory, common, and competitive benefits in each region
- Employee retention: Fair and competitive benefits foster trust and reduce attrition
Example: Deel’s Benefits Tool highlights statutory requirements and competitive benefits, ensuring compliance while enhancing employee satisfaction.

Retaining talent during payroll transitions
Employee retention during M&As often falters due to poor payroll transitions. Deel’s payroll solutions prioritize employee engagement by:
- Ensuring pay consistency: Accurate, timely payments during transitions
- Providing analytics: Insights to identify pay disparities and engagement gaps
- Enhancing onboarding: Fast onboarding processes to maintain morale
M&A audits will often reveal employees who may need visa support as well,” said Dan. “That’s an implication, a very costly implication, that the folks working on the M&A may not even be aware of.
