Overview
Service In Sync and Twenty CRM both organize customers, companies, and deals, but their data models diverge significantly on field-service concepts. Service In Sync models work as Jobs tied to schedules, crews, and client approvals; Twenty models revenue as Opportunities with stage and probability fields. FlitStack AI maps Service In Sync's contacts, companies, jobs, activities, and custom fields into Twenty's People, Companies, Opportunities, Tasks, and custom objects. The migration preserves original timestamps, owner assignments (resolved by email match to Twenty workspace members), and file attachments. Critical limitation: Service In Sync automations, reminders, scheduling rules, and the review-booster feature have no Twenty equivalent — those must be rebuilt in Twenty's workflow builder post-migration. The migration runs via Twenty's CSV import interface and REST/GraphQL API, sequenced so Companies land before People and People before Opportunities (Twenty enforces this dependency order). A 24–48 hour delta window captures any records modified in Service In Sync during the cutover window.

Object mapping
Each row shows how a Service In Sync 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.
Service In Sync
Contact
Twenty CRM
People
1:1Service In Sync contacts migrate as Twenty People records. Each contact's primary company resolves to a Twenty Company via domain match or explicit companyId field. Owner is resolved by email match against Twenty workspace members — unmatched owners are flagged for manual assignment before the full migration runs.
Service In Sync
Company
Twenty CRM
Company
1:1Service In Sync companies map directly to Twenty Companies. Parent-child company hierarchies in Service In Sync map to Twenty's Parent Company relation field if present. Multi-contact companies in Service In Sync maintain their People links via companyId on each Person record after migration.
Service In Sync
Job
Twenty CRM
Opportunity
1:1Service In Sync jobs carry a richer structure than a standard deal — they include scheduling dates, crew assignments, approval statuses, line items, and client sign-off data. FlitStack AI maps the job amount and stage to Twenty Opportunity fields, and stores scheduling metadata (scheduled date, assigned crew) as custom fields on the Opportunity record.
Service In Sync
Job Stage / Status
Twenty CRM
Opportunity Stage
1:1Service In Sync job statuses (e.g., Request, Scheduled, In Progress, Completed, Invoiced, Cancelled) map to Twenty Opportunity stage values via value-by-value mapping. Each stage name from Service In Sync gets a corresponding Twenty stage pick-list value defined in the migration plan before import.
Service In Sync
Custom Field on Contact
Twenty CRM
Custom Field on People
1:1Service In Sync custom fields on contacts (beyond standard name/email/phone) require custom fields in Twenty's Settings → Data Model. FlitStack AI creates the corresponding Twenty custom fields before import and maps values field-by-field. Field type is inferred from Service In Sync data (text, number, date, select).
Service In Sync
Custom Field on Job
Twenty CRM
Custom Field on Opportunity
1:1Service In Sync custom fields on jobs — such as service type, crew size, equipment used, or client-specific metadata — are recreated as custom fields on Twenty Opportunities. Scheduling-derived fields (e.g., crew assignment data) are preserved as text or relation fields depending on their structure.
Service In Sync
Activity / Engagement
Twenty CRM
Task
1:1Service In Sync engagement logs — notes, follow-ups, client communications tied to jobs — migrate as Twenty Tasks. Each Task links to the parent People or Opportunity record via the relation field. Original timestamps and assigned user (resolved by email) are preserved.
Service In Sync
Note / Attachment
Twenty CRM
Note
1:1Service In Sync notes on contacts, companies, or jobs migrate as Twenty Notes. Rich-text formatting is preserved where possible. File attachments from Service In Sync are flagged for manual re-upload — Twenty does not natively store attachments on records, so these require post-migration handling via Twenty Files or an external storage integration.
Service In Sync
User / Owner
Twenty CRM
Workspace Member
1:1Service In Sync users and job owners are matched to Twenty workspace members by email address. Unmatched owners are flagged before migration with a recommendation to invite them to the Twenty workspace first. Once matched, all records receive the correct OwnerId without orphaned assignments.
Service In Sync
Custom Object (if present)
Twenty CRM
Custom Object
1:1Service In Sync custom objects (Enterprise tier) map to Twenty custom objects on the Pro or Organization tier. The target custom object must be pre-created in Twenty Settings → Data Model. Relations between custom objects and standard objects (People, Companies, Opportunities) use Twenty's relation field type and are established after the primary objects are migrated.
Service In Sync
Automations / Workflows
Twenty CRM
Workflow (rebuilt manually)
1:1Service In Sync automations (job reminders, approval routing, follow-up triggers) do not migrate. FlitStack AI exports your automation definitions as a structured rebuild reference so your Twenty admin can recreate equivalent logic in Twenty's workflow builder. This is a manual step — automation rebuild is scoped separately from data migration.
Service In Sync
Review Booster / Reputation Data
Twenty CRM
Not Available
1:1Service In Sync's review-booster feature — which directs post-job customers to leave reviews on Google, Yelp, or Facebook — has no equivalent in Twenty CRM. Review history and review request records are preserved as reference notes, but the active review-automation logic must be rebuilt using a third-party reputation tool post-migration.

Migration approach
Audit Service In Sync data and map to Twenty schema
FlitStack AI connects to Service In Sync via scoped read access and exports all contacts, companies, jobs, activities, custom fields, and user records. We inventory every object and field, flag custom fields that require pre-creation in Twenty's Settings → Data Model, and identify the job-to-opportunity mapping strategy (including which Service In Sync job statuses map to which Twenty Opportunity stages). The output is a migration plan reviewed by your team before any data moves.
Set up Twenty workspace and create custom fields
Before importing data, your Twenty admin (or FlitStack AI) creates the custom fields needed to receive Service In Sync data that has no direct Twenty equivalent — scheduling dates, crew assignments, approval statuses, and any source custom fields. Twenty requires custom fields to exist before CSV import; they cannot be created as part of the import process. We deliver a custom-field creation checklist based on the audit so the workspace is schema-ready before the migration sequence begins.
Invite all Service In Sync users to Twenty by email
Twenty requires workspace members to exist before owner resolution. FlitStack AI identifies every Service In Sync user and owner referenced in the data and confirms they have a corresponding email-matched account in Twenty. Users without Twenty accounts are flagged for invitation before the migration runs. No record lands without a valid assignee or owner — this step prevents orphaned Opportunity assignments in Twenty.
Run a sample migration with field-level diff
A representative slice — typically 100–500 records spanning contacts, companies, jobs, and activities — migrates first using Twenty's CSV import and REST API. FlitStack AI generates a field-level diff comparing source and destination values so you can verify that job statuses map correctly to Twenty Opportunity stages, scheduling dates land in the custom fields, owner resolution by email is accurate, and People are correctly linked to Companies. You approve the sample before the full migration commits.
Execute full migration with delta-pickup window
The full migration runs in sequence: Companies → People → Opportunities → Custom objects → Activities → Notes. A 24–48 hour delta window captures any records created or modified in Service In Sync during the cutover period so Twenty reflects the final state at go-live. FlitStack AI generates an audit log of every record migrated and operation performed. One-click rollback is available if reconciliation reveals data integrity issues — you can re-run the migration without losing the original Service In Sync data.
Deliver automation rebuild reference and post-migration checklist
After data migration, FlitStack AI provides a structured export of your Service In Sync automation definitions (triggers, conditions, actions) mapped to Twenty's workflow builder equivalents. Your Twenty admin uses this as a rebuild guide. The post-migration checklist covers: verifying People-Company-Opportunity relationships, re-uploading Service In Sync file attachments to Twenty Files, configuring Twenty workspace permissions, and testing a sample of Opportunity records to confirm custom field data populated correctly.
