Case studies

Sellsy's implementation team works hands-on with mid-market and ETI customers. For tens of thousands of smaller customers (solo entrepreneurs, very small businesses, growing SMBs), human-touch implementation isn't economical. But the CRM is complex enough that customers who don't get through configuration churn before they renew. Tandem runs implementation for the SMB tail at the same quality the team delivers to larger accounts.

Most teams stop counting an implementation as done when the customer is live. Qonto doesn't. With more than a million customers on the platform, the work that matters most happens after the technical go-live: moving customers from basic checking into the modules that justify the platform's full value. Tandem runs that post-sales implementation work at a scale no team could match by hand.

Spendesk's CS team owns implementation. Every new client needs their accounting setup configured (chart of accounts mapped, journal templates built, integration connected, edge cases handled) before the product is genuinely usable. It's the most critical step in onboarding, and the hardest. Tandem now runs it inside the product, with no manual implementation effort.
