Exact Online or Unit4 Multivers for Dutch business?

Exact Online leads Dutch cloud accounting for SMEs. Unit4 / Multivers is popular among larger companies. Twinfield also appears. We integrate with all Dutch accounting systems.

Can BTW-aangifte be automated?

Partially. Exact Online and AFAS have built-in BTW preparation. Automation via Make/Zapier helps prepare data for periodic submission to Belastingdienst. Full submission is better reviewed by an accountant.

What data does the bol.com Seller API synchronise?

Orders (binnenkomende orders), delivery statuses, stock (voorraad), prices (prijzen), product descriptions. Two-way real-time synchronisation via the bol.com Partner API.
