Overview
Teams migrate from The Practice to Twenty CRM when subscription costs have outgrown the value delivered, or when the desire for data ownership and self-hosted infrastructure becomes a business priority. Twenty CRM runs on PostgreSQL, exposes a REST and GraphQL API with per-plan rate limits (100 req/min on Pro, 200 req/min on Organization), and supports custom objects created via a metadata-driven schema that updates its GraphQL layer dynamically. We map The Practice's client records, appointment logs, and any custom fields into Twenty's People, Companies, Tasks, and custom object tables. The migration carries everything The Practice stores natively into Twenty's object model. The harder problems are resolving The Practice's flat client records into separate People and Companies in Twenty, preserving appointment timestamps and status transitions in Twenty Tasks, and reconstructing any billing or service-rate data that needs a custom object in Twenty. Automation workflows, appointment reminders, and any integration triggers built in The Practice do not migrate — we export their definitions as a rebuild reference for your Twenty admin. Our migration engine uses the Twenty GraphQL API (respecting per-plan rate limits) for standard imports, with bulk operations handled through CSV upload where API throttling is a constraint.

Object mapping
Each row shows how a The Practice 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.
The Practice
Client / Patient Record
Twenty CRM
People
1:1The Practice client records map directly to Twenty's People object. We use the client's primary email as the unique identifier, which Twenty requires for Person record uniqueness checks. Phone, address, and job title fields transfer as direct text fields. If The Practice stores organization name as a field on the client record, we parse it to a separate Companies record and link via companyId.
The Practice
Organization Name (embedded in client)
Twenty CRM
Companies
1:1The Practice embeds organization or company names within client records rather than as a separate entity. We extract unique organization values and create a Companies record in Twenty first (since the import order requires Companies before People). Multi-location clients with one organization name create a single Company record linked to each Person record via companyId.
The Practice
Appointment / Session Record
Twenty CRM
Task
1:1Each appointment in The Practice becomes a Task in Twenty, linked to the corresponding People record. Original appointment date and time map to Task dueDate and startDate fields. Appointment type or session type maps to a custom pick-list field on the Task since Twenty Tasks do not have a native type attribute. We preserve the appointment status (completed, cancelled, no-show) as a custom status field.
The Practice
Service / Session Type
Twenty CRM
Custom Field on Task
1:1The Practice defines service types (e.g., initial consultation, follow-up, therapy session) as appointment categories. We create a custom select field called Service_Type__c on the Task object and populate it via value mapping from The Practice's service type values. If The Practice uses a freeform service type field, we store the raw value as a text field and flag it for deduplication review.
The Practice
Invoice / Billing Record
Twenty CRM
Custom Object: Invoice
1:1Twenty has no native invoice object. We create a custom Invoice object with fields for invoice number, amount, date, client link (relation to People), and status. Invoice line items map to a custom Invoice_Line_Item child object linked via a one-to-many relationship. Your Twenty admin defines the fiscal field names during schema setup.
The Practice
Custom Property / Extended Client Field
Twenty CRM
Custom Field on People
1:1Any custom fields defined in The Practice on the client record (e.g., referral source, insurance carrier, billing tier) become custom fields on Twenty's People object. Field types map as follows: text to TEXT, number to NUMBER, date to DATE, pick-list to SELECT, and boolean to CHECKBOX. Multi-select pick-lists in The Practice map to Twenty's multi-select field type.
The Practice
Client Note / Clinical Note
Twenty CRM
Note
1:1Free-form notes attached to client records in The Practice migrate as Twenty Notes, linked to the corresponding People record. Rich-text formatting in The Practice notes is preserved as plain text where possible; complex HTML-formatted notes are cleaned to text to avoid rendering issues in Twenty's Note body field.
The Practice
Attachment / File
Twenty CRM
Twenty Files (via API)
1:1File attachments on client records (e.g., intake forms, signed documents, session recordings) are re-uploaded to Twenty via the file upload API endpoint. We preserve the original filename and file type. If The Practice stores files in a cloud bucket with a download URL, we fetch and re-upload to Twenty's storage. Inline images in notes are extracted and re-hosted as separate file attachments.
The Practice
Staff / Practitioner Record
Twenty CRM
WorkspaceMember
1:1The Practice practitioner and staff records map to Twenty Workspace Members. We resolve each practitioner by email to match against existing Twenty users. If a practitioner record in The Practice has a name but no email, we flag it for manual assignment in Twenty's user management. Practitioner-client assignment history (which staff member saw which client) is preserved as a custom field on the People record.
The Practice
Location / Branch
Twenty CRM
Custom Field on People / Task
1:1If The Practice manages multiple locations or branches, we create a custom location field on People and Tasks to preserve which location a client is associated with or where an appointment took place. We use a custom SELECT field with value mapping from The Practice's location names. Multi-location practices should confirm all unique location values before migration to ensure the pick-list is complete.
The Practice
Workflow / Automation Rule
Twenty CRM
No Equivalent
1:1The Practice workflows (appointment reminders, client onboarding sequences, follow-up triggers) do not migrate to Twenty. They must be rebuilt in Twenty's workflow builder. We export the workflow definitions from The Practice — trigger type, conditions, and action steps — as a structured reference document your Twenty admin uses to recreate each automation.
The Practice
Integration / Third-Party Connection
Twenty CRM
No Equivalent
1:1Calendar integrations, telehealth connections, billing gateway links, and any third-party tools connected to The Practice do not migrate. They must be reconnected in Twenty using Twenty's REST/GraphQL API, webhooks, or Zapier integration. We document each active connection during the audit phase so your team knows what to rebuild.

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.
The Practice gotchas
No public API means all migration data must be extracted manually
Session recordings and large files require separate manual download
Client group and tag inheritance is not automatically preserved in exports
Contract PDFs are stored as linked files, not embedded records
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 The Practice data and design Twenty schema
We export a full data dump from The Practice — client records, appointments, invoices, custom fields, and file attachment metadata. We document every field name, data type, and pick-list value, then compare it against Twenty's standard object schema. Any custom fields in The Practice are mapped to Twenty custom fields on the appropriate object. We create the custom Invoice object (with your chosen field names) in Twenty and deliver a schema setup checklist before any data is loaded.
Resolve practitioners and create Companies before People
Twenty requires Companies to exist before People can reference them via companyId. We extract unique organization names from The Practice client records, deduplicate them, and create Company records in Twenty first. Simultaneously, we match The Practice practitioner records against Twenty Workspace Members by email. Practitioners without a Twenty account are flagged — your team either creates their accounts first or assigns records to a fallback practitioner. This step sequences correctly so no orphaned foreign keys exist.
Create People records with companyId links
With Companies in place, we create People records in Twenty, linking each to the resolved companyId. Client custom fields from The Practice map to custom fields on People. For clients with no organization in The Practice, we attach them to the default 'Individual' Company record. We preserve the original The Practice client ID as Source_System_ID__c on each People record for traceability.
Migrate appointments to Tasks and invoices to custom objects
Appointment records map to Twenty Tasks linked to the corresponding People record. We preserve appointment date, time, type, status, practitioner assignment, and location. Invoice records load into the custom Invoice object, linked to People via the client relation. Files attach to People and Task records via Twenty's file upload API. All records retain original timestamps as custom datetime fields for reporting continuity.
Run sample migration and field-level diff
Before committing to a full run, we migrate a representative slice — typically 100–300 records spanning clients, appointments, and invoices. We generate a field-level diff comparing source and destination values so you can verify appointment type mapping, practitioner assignment, company linking, and custom field population. This preview run validates that field transformations work as expected and that your data will display correctly in Twenty's interface. You sign off on the diff before the full migration runs.
Execute full migration with delta-pickup and post-migration audit
The full migration runs in batches, respecting Twenty's API rate limits. A delta-pickup window (24–48 hours after initial load) captures any new or modified records created in The Practice during cutover. We generate an audit log listing every record created, its source ID, and any warnings (e.g., unmatched practitioners, unmapped pick-list values). One-click rollback reverts all migrated data if reconciliation fails. Post-migration, we run a spot-check validation against your defined thresholds.
