Rootline
Payment Processing — Onboarding
Document Version: March 2026
Onboarding Guide

Preparing for Your
Payment Account

Everything you need to activate your payment account with your partner via the Rootline platform. Please have the following information and documents ready.

Your partner partners with Rootline to enable card payments for your business. To activate your payment account, we need to collect some information about your company and its owners — this is legally required as part of the mandatory identification and verification process.

The onboarding form consists of 7 steps and can be completed in one sitting. You will receive a link from your partner.

Documents — please prepare in advance
These documents will need to be uploaded during onboarding (PDF or image, max. 10 MB).
