Sellsy alternative: why SMEs choose a custom no-code solution

A typical migration spans four to eight weeks. Week one covers data export and schema mapping. Weeks two through four focus on rebuilding core workflows—contacts, invoicing, pipeline tracking—in Ksaar. Week five includes user acceptance testing and training sessions. The final weeks handle parallel runs, where both systems operate until your team confirms accuracy. Most SMEs go live without disrupting daily sales or billing cycles.

Sellsy subscriptions range from fifty to one hundred fifty euros per user per month, depending on modules. A five-user team pays three to nine thousand euros annually. A custom Ksaar build for similar functionality costs eight to fifteen thousand euros upfront, plus two hundred to four hundred euros monthly for hosting and maintenance. Break-even usually occurs between month twelve and eighteen, after which you save thousands each year while enjoying unlimited user seats and bespoke features.

Yes. Many clients run Sellsy in read-only mode for historical data while new transactions flow through Ksaar. We can also replicate specific Sellsy features you value—custom quote templates, automated reminders, or client portals—and enhance them with deeper integrations. Migration is phased, so critical functions like invoicing or contract renewals remain uninterrupted. You decide which modules move first and which stay until the new system proves stable.
