Overview
coreplus is a practice management platform built around clients, practitioners, appointments, service types, and referrers — with a REST API that exposes these as discrete endpoints for server-to-server integration. Twenty CRM models everything as standard objects (People, Companies, Opportunities, Notes, Tasks) with a metadata-driven custom object layer accessible via GraphQL and REST. The migration challenge is translating coreplus's appointment-centric workflow into Twenty's task-based model, mapping referrer relationships into custom objects or company associations, and preserving invoice and service-type metadata as custom fields on People or custom objects. FlitStack sequences the migration so People records are created before their associated Tasks, invoice data is stored as a custom object with a relation to the relevant Person record, and practitioners are matched to Twenty Workspace Members by email before their assigned appointments are imported. We handle the CSV export from coreplus, the field-level transformation against Twenty's schema, and the bulk import via Twenty's REST API — staying within the 100–200 requests-per-minute rate limit on the Pro and Organization plans. Views, workflows, practitioner scheduling rules, and availability logic must be rebuilt manually in Twenty's workflow builder or via external automation tools such as n8n or Zapier.

Object mapping
Each row shows how a coreplus object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
coreplus
Client
Twenty CRM
People
1:1coreplus Client records map directly to Twenty People. The coreplus client record carries name, email, phone, address, and create date — these map to the corresponding Twenty People fields. coreplus clients without a primary referrer link land as standalone People records. Original coreplus client ID is preserved as Source_System_ID__c for delta-run deduplication.
coreplus
Client → Practitioner link
Twenty CRM
People → Workspace Member
1:1coreplus links clients to practitioners via the appointment model. In Twenty, practitioner resolution happens by matching practitioner email to a Twenty Workspace Member. Unmatched practitioners are flagged before migration — your team either creates their Twenty accounts first or assigns records to a fallback member. Once resolved, the practitioner assignment is stored as a custom relation field on the People record.
coreplus
Appointment
Twenty CRM
Task
1:1coreplus appointments become Twenty Tasks. Each appointment's date, time, duration, service type, and status (completed, cancelled, no-show) are mapped to Task fields. The Task is linked to the People record representing the client. Appointment status is stored as a custom select field on the Task. Practitioner attribution is preserved via the Workspace Member relation on the Task.
coreplus
Practitioner
Twenty CRM
Workspace Member
1:1coreplus practitioner records map to Twenty Workspace Members. FlitStack resolves practitioner email against Twenty user accounts to build the Owner/User relation for tasks and records. coreplus practitioner specialties and position data migrate as custom fields on the Workspace Member record for reference.
coreplus
Referrer
Twenty CRM
Company
1:1coreplus referrers (clinics, referring doctors, partner organizations) map to Twenty Companies. Referrer name maps to Company.name, referrer contact details map to standard Company fields, and the referrer relationship to clients is stored as a custom relation field (Referrer_ID__c) linking People to the referral Company. If your coreplus referrers are individual people rather than organizations, they become People records instead.
coreplus
Invoice
Twenty CRM
Custom Object (Invoice)
1:1coreplus invoices are stored as a Twenty custom object named Invoice. Fields include invoice number, amount, date, status (paid/unpaid/overdue), and client relation. The Invoice custom object is created via Settings → Data Model before migration. Invoice records are linked to the relevant People record representing the client.
coreplus
Service Type
Twenty CRM
Custom Object (Service Type)
1:1coreplus service types (service category, fee, stock level) become a Twenty custom object. Each Service Type record carries the service name, fee amount, and stock indicator. Service types are linked to Tasks (via appointment mapping) so Twenty reports can filter by service type without relying on external data.
coreplus
Availability Slot
Twenty CRM
Custom Object (Availability)
1:1coreplus practitioner availability slots map to a Twenty custom Availability object. Each record holds practitioner (Workspace Member), date, start/end time, and availability status. These are standalone records linked to the practitioner; Twenty's standard calendar views can be filtered or extended to display them alongside Tasks.
coreplus
Draft Note
Twenty CRM
Note
1:1coreplus draft notes attached to client records migrate as Twenty Notes. The note body, author, create date, and client relation are preserved. Notes are linked to the relevant People record. Rich-text formatting is converted to plain text where the source format is not fully compatible with Twenty's note storage.
coreplus
Attachment / File
Twenty CRM
Twenty Files (linked to record)
1:1coreplus file attachments on clients, appointments, or invoices are downloaded and re-uploaded as Twenty Files. Each file is linked to its parent record (People, Task, or custom Invoice object) using Twenty's attachment relation. File size limits on the destination plan apply — large files are chunked or flagged for manual re-upload.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
coreplus gotchas
Supervisor-level access required for data backup
No native bulk-export API for appointments or invoices
MYOB export produces three separate files requiring manual import
Tier-based API access and undocumented rate limits
Body charts are embedded in notes and not independently exportable
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Audit coreplus data model and export all objects in dependency order
FlitStack begins by querying coreplus's API endpoints for all object types — clients, practitioners, appointments, referrers, invoices, service types, and availability slots — and downloading the corresponding CSV exports. We verify record counts, check for NULL values in required fields (email, name, date), and flag duplicate client records. This audit output becomes the source-of-truth record manifest used throughout the migration to validate completeness and detect delta records created during the cutover window.
Provision Twenty schema: custom objects, fields, and Workspace Members
Before any data is imported, FlitStack delivers a schema setup plan specifying the Invoice and Service Type custom objects (field names, types, pick-list values), the Availability custom object for practitioner slots, and any custom fields on People (Source_System_ID__c, Coreplus_Create_Date__c) or Workspace Members (Specialty__c). We also deliver a practitioner-to-Workspace-Member resolution table so your team can invite practitioners to Twenty and confirm their email addresses match the coreplus practitioner records before appointment imports run.
Migrate core entities first: People, Companies, then Tasks
Twenty requires that relation targets exist before records referencing them can import. We sequence the migration as: (1) Companies from referrers, (2) People from clients and practitioners, (3) Tasks from appointments linked to People by email-resolved IDs, (4) custom object records (Invoice, Service Type, Availability). Tasks are created with status=open by default; appointment status from coreplus is stored in a custom Task status field for post-migration review.
Run a sample migration with field-level diff and relationship validation
A representative slice — typically 200–500 records spanning clients, practitioners, appointments, referrers, and invoices — migrates into Twenty via the API. FlitStack generates a field-level diff comparing source values against destination fields, verifying that email lookups resolved correctly, appointment practitioner assignments resolved, and custom object relations linked properly. You review the diff and approve the field mapping before the full migration commits.
Execute full migration with delta-pickup window and one-click rollback
The full migration runs against Twenty's REST API, staying within the 100–200 req/min rate limit by pacing batch requests. A delta-pickup window (typically 24–48 hours) captures any new clients, appointments, or invoice records created or modified in coreplus during the cutover. Audit logs capture every operation, and one-click rollback reverts the Twenty workspace to its pre-migration state if reconciliation finds data integrity issues. Post-migration, your team rebuilds appointment-based scheduling workflows in Twenty's workflow builder or via n8n.
