Overview
Moving from Biztim Business Management Software to Twenty CRM addresses two persistent pain points: the absence of a public API on all tiers except Enterprise, and the lack of third-party integrations that forces manual data exports when growing businesses add tools to their stack. Bizstim's data model organises around Clients, Practitioners, Services, and Payments with practitioner_id and group_id foreign keys that must be preserved during extraction. We extract through Bizstim's paginated REST API (1000 req/hour per key, Services endpoint capped at 100 records per page), resolve parent-record lookups at migration time, and load into Twenty as Person records, Opportunities, and custom object entries. SMS reminders, email automations, and on-demand session links do not migrate because they are tied to Bizstim's internal automation engine and temporary session-scoped tokens respectively; we deliver a written automation inventory for the customer's admin to rebuild in Twenty.

Object mapping
Each row shows how a Bizstim Business Management Software 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.
Bizstim Business Management Software
Client
Twenty CRM
Person
1:1Bizstim Client records map directly to Twenty CRM Person records. We extract all standard contact fields including name, email, phone numbers, address, and any custom fields scoped to the client record. The Bizstim client status flag maps to Twenty's Person status field. Notes and free-text fields attached to the client record migrate as Twenty Files linked to the Person via the attachment relationship. Client records are imported first in the dependency order because they are referenced by practitioner_id on session records and by client_id on payment records.
Bizstim Business Management Software
Practitioner
Twenty CRM
Person
1:1Bizstim Practitioner records map to Twenty CRM Person objects with a practitioner role designation in a custom field or tag. The practitioner_id is preserved as an external identifier for relationship resolution during session record migration. practitioner_wage settings from Bizstim migrate as custom fields on the Person record. We deduplicate against Staff records using staff_id to avoid creating duplicate Person entries when both Practitioner and Staff endpoints return overlapping data. The mapping assumes the customer has reviewed and confirmed that Practitioner and Staff records represent distinct individuals in their business.
Bizstim Business Management Software
Service
Twenty CRM
Custom Object or Opportunity
1:manyBizstim Service records with a group_id represent individual offerings within a bundle; those without group_id are standalone services. We map standalone services to Twenty custom object entries with service name, cost, session count (group_num), and practitioner wage defaults as structured fields. Services with group_id are grouped by their parent group_id, and the group itself maps to a Twenty Opportunity or custom object that bundles the child service entries. This preserves the service package structure that Bizstim customers use for tutoring sessions, appointments, and bundled service offerings.
Bizstim Business Management Software
Service Group
Twenty CRM
Custom Object or Opportunity
1:1Bizstim service_group_names table entries define the parent group structure that organises related services via group_id. We export the group hierarchy and map each group to a Twenty Opportunity with the group name as the opportunity name, using the group_id as an external reference key. Child services are linked to the parent group Opportunity via a custom lookup field. Service groups that contain no child services are imported as standalone custom object entries without a parent relationship.
Bizstim Business Management Software
Payment
Twenty CRM
Opportunity or Activity
1:1Bizstim Payment records track amounts, dates, and client associations via client_id. We map each payment to a Twenty Activity record attached to the corresponding Person (resolved from client_id), with the payment amount and currency stored in custom fields on the Activity. For customers using Bizstim's invoice feature, the invoice record migrates as a separate Activity with invoice number, date, and line-item details. Currency fields are stored as decimal values and migrated as-is with the currency code preserved in a text field until the customer's admin confirms the currency configuration in Twenty.
Bizstim Business Management Software
Calendar / Availability Slot
Twenty CRM
Event
1:1Bizstim Client records contain minTime, maxTime, slotDuration, and sessionLimit fields that define individual availability windows for each client. We extract these as structured availability rules and map them to Twenty Event records with the practitioner and client linked via the Person relationship. Session scheduling data migrates as Events with the start time, duration, and attendee information preserved. The customer's admin rebuilds the recurring availability pattern in Twenty's calendar after migration because the calendar preference data does not include the practitioner's own schedule constraints.
Bizstim Business Management Software
User
Twenty CRM
User
1:1Bizstim User records return login information and role data for system users. We export the user table to identify owner and assignee mappings that apply to Practitioner and Client records. Owner resolution is performed by matching the Bizstim user email to the email of the corresponding Person in Twenty, and the owner assignment is set on the migrated records. Any Bizstim User without a matching Person in Twenty is flagged for the customer's admin to provision a Twenty User account before record import resumes.
Bizstim Business Management Software
Staff
Twenty CRM
Person
1:1Bizstim Staff records are queryable via GET and in most Bizstim accounts overlap with Practitioner records. We export Staff records and consolidate them with Practitioner records, deduplicating by staff_id against the practitioner_id list. Any Staff records without a corresponding Practitioner entry are migrated as separate Person records with a staff role designation. This mapping ensures that businesses using Staff and Practitioner as distinct objects do not lose staff-specific data during the migration.
Bizstim Business Management Software
On-Demand Link
Twenty CRM
Not migrated
1:1On-demand encrypted links are session-scoped temporary tokens that generate session access URLs tied to a custom student identifier and agent IDs. These tokens are not portable across systems and are not migrated by design. The customer's admin sets up new session access mechanisms in Twenty using Twenty's built-in meeting link integration or a third-party video tool. We document the count of active on-demand links during scoping so the admin accounts for this gap in their migration checklist.
Bizstim Business Management Software
Note / Attachment
Twenty CRM
File
1:1Bizstim client notes and free-text fields are included in the Client export and migrate as Twenty Files attached to the corresponding Person record via the file relationship. Binary attachments or file uploads stored within client records must be identified separately during the scoping call, as the Bizstim API does not expose a dedicated attachment endpoint and file storage requires manual export from the Bizstim interface. We include file migration as a line item in the scoping document with a note that customer-assisted export is required for binary attachments.
Bizstim Business Management Software
Custom fields (client-extended)
Twenty CRM
Custom fields (Person)
lossyBizstim allows extended custom fields on Client and Practitioner records. We export the full custom field schema during scoping, map each custom field to an equivalent custom field in Twenty on the Person object, and include field-type validation (text, number, date, picklist) in the mapping document. Fields that do not have a direct Twenty equivalent are flagged for the customer's admin to confirm whether a custom field, tag, or note is the appropriate destination.

Custom fields (service-extended)
Twenty CRM
Custom fields (Custom Object or Opportunity)
lossyService records in Bizstim support extended custom fields beyond the standard cost, session count, and practitioner wage fields. We export the service custom field schema during scoping and map each field to a corresponding custom field on the Twenty destination object (Custom Object or Opportunity depending on the mapping strategy). Fields with picklist or multi-select values are mapped to Twenty picklist or multi-select fields with the value set validated against Twenty's allowed values.

Pair-specific challenges
Migration approach
Account tier verification and scoping call
We confirm that the customer's Bizstim account holds an active Enterprise licence, because API key generation is gated to this tier and represents a hard prerequisite for migration-grade data extraction. If the customer does not hold an Enterprise licence, we pause the migration scope and provide a cost comparison for upgrading versus proceeding with a manual export-assisted migration. We then conduct a scoping call to audit the full record inventory: Client count, Practitioner and Staff count, Service catalogue size with group_id hierarchies, Payment and invoice record volume, Calendar availability slot density, and any custom fields on each object. The scoping output is a written migration plan with record counts and a timeline estimate.
Schema design in Twenty CRM
We design the destination schema in Twenty based on the scoping inventory. If the customer uses service bundles and group_id hierarchies, we configure custom objects or Opportunity structures to represent service packages and their child offerings. Practitioner and Staff records map to Person objects with role designations. Availability slot data maps to Event records with the client and practitioner linked. We pre-create all custom fields on the Person and custom object schemas before any data import begins, including field types (text, number, picklist, multi-select, date) validated against Twenty's allowed values. Schema design is validated in a Twenty test environment before production migration begins.
Pilot extraction with pagination and rate-limit validation
We run a pilot extraction from Bizstim using paginated REST API calls with exponential backoff on rate-limit responses. For the Services endpoint we validate the 100-record-per-page cap and confirm that the group_id hierarchy is preserved across paginated responses. For large accounts we request a secondary Enterprise API key and validate that parallel extraction does not trigger duplicate-record warnings. The pilot extraction covers a representative sample of each object type and produces a record-count reconciliation report that the customer reviews before production migration is scheduled.
Record migration in dependency order
We run production migration in record-dependency order to satisfy foreign key constraints. Person records (Clients, Practitioners, Staff) are migrated first with external identifiers preserved. Service Group parent records are migrated next, followed by individual Service child records linked via group_id. Payment and invoice records are migrated as Activity entries linked to the corresponding Person. Availability slot data migrates as Event records linked to the client and practitioner Person records. Notes and file attachments migrate last. Each phase emits a row-count reconciliation report that the customer validates before the next phase begins.
Automation inventory and post-migration rebuild handoff
We deliver a written automation inventory documenting every active Bizstim SMS reminder, email notification, and session slot automation with its trigger conditions, target recipients, and message content. The document includes recommendations for rebuilding each automation in Twenty's system (manually, using a third-party workflow tool, or through a developer integration). We do not rebuild automations as part of the standard migration scope. The customer uses the inventory to assign automation rebuild tasks to their admin team or a Twenty implementation partner after cutover.
Cutover, final reconciliation, and hypercare
We freeze Bizstim writes during the cutover window and run a final delta migration of any records modified during the migration window. After cutover we enable Twenty as the system of record and conduct a full reconciliation: record counts by object, spot-checks on 25-50 records against the source, and validation of relationship links (Person-to-Event, Opportunity-to-Activity). We support a one-week hypercare window where we resolve any data quality issues raised during the customer's first week of active use. We do not provide post-hypercare admin support, ongoing training, or workflow rebuild as standard scope.
