50+ pluginsTwenty offers a modern, extensible CRM. If the next requirement is an operational application, evaluate the domain modules you can start with in Open Mercato rather than building every sales-operation record from a blank object.
Both platforms expose source code and support customization. Compare the module architecture and licence of the exact editions you plan to use, then prototype the workflow that differentiates your application.
Map People, Companies, Opportunities, custom objects, relations, notes, tasks and record owners. Rehearse the relationships and daily workflow with a representative sample before committing to the cutover.
Link companies and people to deals, addresses, notes and activities. Extend the records with fields that describe your business.
Configure stages and track deal value, probability, expected close and ownership in board or list views.
Use the sales and catalog modules for quotes, orders, products, payments and shipment records. Implement the handoffs and provider connections your process needs.
Extend the TypeScript application with your own entities, modules and workflows. Assess email/calendar synchronization, workflows, custom objects and deployed edition features as explicit migration work.
Green checks show available capabilities in the stated scope. Arrows identify implementation work, including the specialist features your team may need to retain.

Inventory People, Companies, Opportunities, custom objects, relations, notes, tasks and record owners. Keep original identifiers and agree how each record maps to the new application.

Load a representative sample, validate permissions and relationships, and test a real customer journey from first activity to the operational handoff.
Compare record counts and key totals, retain an accessible archive where needed, handle final changes and agree rollback, training and support ownership.
When you need an owned, extensible CRM and operational application, and have a team or partner to implement and run it. Twenty CRM can remain the better fit when its ready-to-use managed experience already matches your requirements.
No automatic feature transfer is assumed. Review email/calendar synchronization, workflows, custom objects and deployed edition features. The core provides CRM and sales modules; specialized capabilities require configuration, integrations or development.
Compare the same scope over the same period: current subscriptions and administration versus implementation, migration, hosting, maintenance, support and provider usage. The MIT core has no licence charge; a production service still has costs.
Yes, a phased architecture can be scoped. Define the system of record for each entity, the synchronization rules and failure handling, then validate them before moving users.
Start with your record map, required integrations and the three changes that would make the biggest difference to your team.
