Frequently asked questions

What people usually ask us before starting.

Can't see yours? Write to us at info@zinco.ai and we'll reply within 24h.

You can hire one, two or all four. Many clients start with accounting and tax and then add labour. The advantage of having them with us is that the areas talk to each other without you having to coordinate anyone.
We handle everything: information request, change of representative with the tax authority, data transfer and historical review of the last 4 years. The change takes between 10 and 20 days and you only need to make one call.
Flat monthly fee, adjusted to the size and complexity of your company. No surprise invoices or "this query is extra". For one-off operations (round, acquisition, restructuring) we give you a closed quote upfront.
One point of contact per company, who knows you, knows your business and coordinates the rest of the team internally. You have a name, a phone and an email. We handle the rest.
We work with hospitality, retail, SaaS, venture capital, family offices, art professionals and many more. On the first call we tell you which clients we have in your sector and who would be your point of contact based on prior experience.
Zinco's own platform, integrated with the main management tools, banks and ERPs. You see your accounts, invoices, payrolls and filings in one place, from mobile or desktop. And if something doesn't fit, we integrate it.
