Gerlof Sijtsma and Nico Koppel have known one another for 20 years, as Gerlof explains: “Back then I held a number of director-cum-shareholderships. It was through a mutual business acquaintance – Doorneweerd’s pension consultancy, with whom Koppel shared a building – that we were brought into contact with one another. Until then I had always taken care of all the paperwork myself.” Gerlof recollects that when AdSysCo was launched in 2003 “we simply carried on our relationship with Koppel by taking them with us to our current business”

Koppel invests in lasting customer relationships, as Gerlof confirms: “We would have parted ways years ago had I been less than happy with Koppel, or Koppel with us for that matter.” A proactive approach and a keen understanding of the sector in which their customer operates ensure that their tax advice keeps matching the latest requirements.

Gerlof: “There are certain services for which fiscally speaking it makes sense to have a tax consultant on tap. AdSysCo is made up of several economists, which makes us perfectly capable of seeing to our own accounts and preparing our own financial statements. The tax returns are a different matter. That and the payroll records and corresponding tax matters is where we rely on Koppel. Sorting out your taxes, that’s Nico’s forte.”

AdSysCo operates several private limited-liability companies whose tax matters Koppel oversees. Says Gerlof: “Nico advises us not only on the set-up of the holding companies and the operating companies these straddle but on the shareholders’ personal holding companies as well, and takes care of our income tax returns and associated business. All in all it’s a fair bit of consultancy work!” He continues: “As director-cum-controlling shareholder you have to take the personal interests – such as personal holding companies – into account. Everything is intertwined and it all has to mesh, which makes it super handy to have a single tax consultant take care of everything.”
