Global Expat Pay helps global mobility teams bring data collection, analysis, reporting and payments together in one place, so they save time, cut costs and improve accuracy. By integrating Certino's tax engine, it can now also calculate shadow payroll quickly and accurately, for employees on international assignments and for remote and flexible workers. The aim is simple: to give internationally mobile employees the same smooth experience as colleagues working in their home country. ### Consultancy and technology, together Global Expat Pay combines expert consultancy with technology. This lets companies of any size digitise and automate their global mobility processes, from payroll instructions and tax year-end reporting to finance. Shadow payroll calculations are now part of that offer. ### Why it matters Global mobility is getting more complex. Remote working and international assignments are more common, and tax rules keep changing. That makes shadow payroll one of the most important, and most difficult, parts of the job. At the same time, the pressure on mobility teams is growing: - **Leaders want better data,** fast and accurate, to support their decisions. - **Tax authorities are more active,** so data needs to be shared quickly and payroll reporting needs to be complete and correct. Together, Global Expat Pay and Certino help mobility teams meet these demands simply and cost-effectively. ### What they said **Mike Hibberd, Founder and CEO, Global Expat Pay:**  “We work with global mobility leaders to understand their needs, their data, and other operational challenges – and to determine how our consultancy and technology enabled managed service can be best applied to make their programme work better. It was becoming increasingly clear that calculating shadow payroll was a missing piece of the puzzle for us – yet this is also an incredibly specialist area that demands a huge amount of expertise. That’s why we have partnered with Certino, the best-of-breed solution in this area, to deliver automated shadow payroll calculations to our clients under one simple umbrella service.” Richard McBride, Managing Director, Certino: “Global Expat Pay’s agility and unique solution make it a very special business – and one we’re hugely excited to partner with. Within the global mobility industry, the advantages of “White glove / Tech” solutions are becoming increasingly apparent. Those that combine quality consultancy with pioneering technology to deliver an exceptional experience to clients. The combined Global Expat Pay / Certino proposition is one such solution. I look forward to working with the business to create a more robust, data-let global mobility function, while improving the experience of mobility managers everywhere.”  For more information please contact [enquiries@certino.com](mailto:enquiries@certino.com)  Share [mailto:?subject=Global+Expat+Pay+partners+with+Certino+to+add+shadow+payroll+calculations+for+clients&body=https%3A%2F%2Fwww.certino.com%2Fblog%2Fglobal-expat-pay-partners-with-certino-to-provide-shadow-payroll-calculations-to-clients](mailto:?subject=Global+Expat+Pay+partners+with+Certino+to+add+shadow+payroll+calculations+for+clients&body=https%3A%2F%2Fwww.certino.com%2Fblog%2Fglobal-expat-pay-partners-with-certino-to-provide-shadow-payroll-calculations-to-clients) ![](https://www.certino.com/hubfs/R6SD7740%20copy-1.jpg) ### Tom Lockyer Tom is CEO of Certino, where he leads the company's work to make hypo tax, gross-up and shadow payroll calculations accurate, consistent and easy to check.
