Overview

What this migration involves

Advance Practice Management Suite organizes healthcare operations around patients, appointments, billing records, and insurance claims. It stores contact data, visit histories, and payer relationships in a billing-centric schema. Twenty CRM is a general-purpose open-source CRM with standard People, Companies, Opportunities, Tasks, and Notes objects — any of which can host custom fields. No native billing or insurance object exists in Twenty, so those source concepts become custom fields or custom objects during migration. FlitStack AI extracts records from the source via its export API, resolves owner relationships by email match against Twenty workspace members, maps patient contacts to People, organizations to Companies, and active cases or opportunities to Opportunities. Attachments and files are downloaded and re-uploaded to Twenty's file storage. Workflows, billing rules, and insurance payer configurations do not migrate — those are destination-side logic that must be rebuilt using Twenty's workflow builder or exported as reference documents for a developer. The migration uses Twenty's REST API (200 requests per minute on Organization tier) with batch inserts and a 24-hour delta-pickup window for in-flight changes during cutover.

Why teams make this switch

Two sides of the same decision

Leaving

Advance Practice Management Suite logo

Advance Practice Management Suite

What's pushing teams away

  • Implementation and initial setup require several weeks of preparation, which frustrates practices expecting a faster deployment timeline.
  • Customization options are perceived as limited by users who need highly specialized workflow configurations for niche specialties.
  • Long-term contract commitments make it difficult for growing or changing practices to exit without significant financial penalty.

Choosing

Twenty CRM logo

Twenty CRM

What's pulling them in

  • Top open-source CRM on GitHub with 40.6K stars, giving teams full source code access and infrastructure ownership without per-feature licensing surprises.
  • Free self-hosting under AGPL-3.0 means unlimited users and custom objects for the cost of cloud infrastructure alone, typically $20–100/month.
  • Pricing page explicitly mocks competitors for charging add-on fees for API access, webhooks, and workflows — transparency that resonates with RevOps teams burned by Salesforce.
  • Unlimited custom objects and fields with no price impact, letting teams shape the data model to their business rather than forcing business into rigid schemas.
  • Modern TypeScript/React/PostgreSQL stack means developer-led teams can extend, self-host, or integrate without fighting legacy architecture.

Object mapping

How Advance Practice Management Suite objects map to Twenty CRM

Each row shows how a Advance Practice Management Suite 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.

Advance Practice Management Suite

Patient / Contact

maps to

Twenty CRM

People

1:1
Fully supported

Advance Practice Management Suite patient records map directly to Twenty's People object. Name, email, phone, address, and job title fields map to their Twenty equivalents. Original create timestamps are preserved as a custom field since Twenty sets CreatedDate at migration time. Owner resolution runs by email match against Twenty workspace members.

Advance Practice Management Suite

Organization / Practice

maps to

Twenty CRM

Companies

1:1
Fully supported

The practice or organization entity in the source becomes a Companies record in Twenty. Practice name maps to Companies.name, domain/website maps to Companies.website, industry is set to 'Healthcare' or mapped to a custom pick-list. If the source stores parent-child practice relationships, those map to Companies' built-in parent-company relation.

Advance Practice Management Suite

Insurance Payer

maps to

Twenty CRM

Custom Object: InsurancePayer

1:1
Fully supported

Twenty has no native insurance or payer object. We create a custom InsurancePayer object with fields for payer name, policy type, and coverage notes, then link it to the corresponding People record via a custom relation field. If no InsurancePayer records exist, payer information collapses into a text field on the People record.

Advance Practice Management Suite

Case / Encounter

maps to

Twenty CRM

Opportunities

1:1
Fully supported

Active cases or patient encounters map to Twenty Opportunities. The case name becomes Opportunity.name, case status maps to a custom stage pick-list, and any monetary value (billing amount, expected reimbursement) maps to Opportunity.amount. If the source uses multiple case types, those map to distinct Opportunities with type labels so filtering works in Twenty's kanban view.

Advance Practice Management Suite

Appointment

maps to

Twenty CRM

Tasks

1:1
Fully supported

Scheduled appointments from the source become Tasks in Twenty linked to the corresponding People or Companies record. Appointment date maps to Task.dueDate, appointment type maps to Task.body or a custom Task.type field, and the assigned provider resolves by email to a Twenty workspace member. Completed appointments retain their original date as a custom completion-date field.

Advance Practice Management Suite

Billing Record / Claim

maps to

Twenty CRM

Custom Object: BillingClaim

1:1
Fully supported

Billing claims have no native equivalent in Twenty's standard schema. We create a BillingClaim custom object with fields for claim ID, amount, status (submitted, paid, denied), and date. The claim links to the People record of the patient and the Companies record of the practice. Claim status values require value-by-value mapping since the source billing statuses are billing-specific.

Advance Practice Management Suite

Notes / Clinical Notes

maps to

Twenty CRM

Notes

1:1
Fully supported

Clinical or administrative notes from the source map to Twenty's built-in Notes object. Each note is linked to the related People or Companies record. Original note timestamps and author information are preserved in note metadata fields. Rich-text formatting in source notes is maintained where the source export format supports it.

Advance Practice Management Suite

Document / Attachment

maps to

Twenty CRM

Twenty Files

1:1
Fully supported

Patient documents, signed forms, and uploaded files from the source are downloaded, uploaded to Twenty's file storage, and linked to the corresponding People or Companies record. File size limits on the destination apply (Twenty's default file upload limit). Inline images in clinical notes are extracted and re-hosted as attachments.

Advance Practice Management Suite

Provider / Staff

maps to

Twenty CRM

WorkspaceMember

1:1
Fully supported

Source provider and staff records are matched by email to existing Twenty workspace members. If a provider has no matching workspace member, they are created as a Twenty person record flagged as a provider. Provider specialties and credentials map to custom fields on that person record.

Advance Practice Management Suite

Custom Patient Property

maps to

Twenty CRM

People (custom field)

1:1
Fully supported

Any custom properties on patient records (e.g., referral source, preferred contact method, insurance group ID) are migrated as custom fields on the Twenty People object. Field type is inferred from the source schema: text fields map to TEXT, pick-lists map to SELECT, date fields map to DATE. Custom field creation in Twenty requires Settings > Data Model > People > Add Field before migration inserts run.

Advance Practice Management Suite

Workflow / Automation

maps to

Twenty CRM

No Equivalent

1:1
Fully supported

Workflows, appointment reminder sequences, and billing alert automations from the source do not migrate. They require manual rebuild in Twenty's workflow builder or in an external automation tool. FlitStack exports workflow definitions as a reference JSON document for the rebuild team. The source system remains fully operational during this phase.

Pair-specific challenges

  • Twenty's 20,000-record per-export cap affects large patient databases

    Twenty's CSV export is capped at 20,000 records per file. If your Advance Practice Management Suite instance has more than 20,000 patient records, a single CSV export from Twenty will not cover the full dataset. FlitStack handles this by running multiple filtered exports from the source (e.g., segmented by date range or practice unit) and sequencing them into Twenty via the REST API batch endpoints. Source-side export must support the same segmentation strategy — if the source only allows a single full export, a multi-pass API extraction plan is built before migration begins.

  • Billing and insurance concepts have no native destination equivalent

    Advance Practice Management Suite stores payer relationships, insurance group IDs, claim statuses, and billing amounts as first-class entities. Twenty CRM has no native billing, payer, or insurance object. These concepts must become either custom fields on the People record or a custom BillingClaim custom object. FlitStack creates the custom object schema in Twenty (via Settings > Data Model > New Object) before inserting any records, so the destination schema is ready before the first data load. Custom field creation requires a workspace admin with the proper permissions — this is surfaced in the pre-migration checklist.

  • Workflows, reminders, and billing automations cannot migrate

    Appointment reminder sequences, insurance follow-up alerts, and billing claim status workflows in the source do not translate to Twenty's workflow builder because the trigger events and action types are domain-specific. FlitStack exports the source workflow definitions as a structured JSON reference file. The rebuild in Twenty's workflow builder must be done manually or by a developer using Twenty's workflow triggers (record-created, record-updated, field-changed) — the equivalent triggers exist but the logic must be authored fresh. This limitation is disclosed upfront so teams budget rebuild time.

  • API rate limits on Twenty's REST endpoint require batch engineering

    Twenty's Organization tier caps the REST API at 200 requests per minute. Large migrations with 10,000+ records require batch insertion (Twenty supports batch create endpoints with up to 100 records per request) and retry logic to handle 429 Too Many Requests responses gracefully. FlitStack implements exponential backoff and batch-window pacing so the migration runs within rate limits without manual intervention. The Pro tier's 100 req/min limit requires tighter batching — this is evaluated during scoping.

  • Custom field creation must precede data insertion in Twenty

    Twenty requires custom fields to exist before records referencing them can be inserted via the API. If a source patient record has five custom properties, those five custom fields must be created in Twenty's data model before any People records are loaded. FlitStack generates the complete schema diff between source custom properties and Twenty's field list, creates the missing fields in a pre-flight step, and only then runs the record migration. Fields created mid-migration can cause insert failures on previously loaded records.

Migration approach

Six steps for a successful Advance Practice Management Suite to Twenty CRM data migration

  1. Audit source data and design Twenty schema

    FlitStack connects to the source platform's export API and inventories all object types, record counts, custom property definitions, and relationship structures. For each source object that lacks a native Twenty equivalent (e.g., BillingClaim, InsurancePayer), we generate the custom object schema and field definitions and submit them to Twenty's data model API. The result is a schema-ready Twenty workspace before any data is moved. Record counts are reconciled against source totals so nothing is assumed missing.

  2. Match owners and providers by email

    Source providers and staff records are matched against Twenty workspace members by email address. FlitStack retrieves the member list from Twenty via the `/users` endpoint, normalizes email strings (trimming whitespace, lowercasing), and attempts an exact match. Matched records receive the correct `assigneeId`; unmatched providers are flagged in a mismatch report and may be created as new workspace members or assigned to a fallback owner. No People, Task, or Opportunity record lands in Twenty without an owner resolved.

  3. Sequence the migration by foreign-key dependency

    Twenty requires the 'one' side of relationships to exist before the 'many' side can reference them. The migration runs in this order: (1) Companies first, (2) People second with companyId linking to Companies, (3) Opportunities third with personId and companyId linking to People and Companies, (4) Tasks and Notes fourth linked to their parent records, (5) custom objects last. This ordering respects Twenty's referential integrity constraints and prevents orphaned foreign keys.

  4. Run a sample migration with field-level diff

    A representative slice — typically 200–500 records spanning People, Companies, Opportunities, and Tasks — migrates first. FlitStack generates a field-level diff comparing source values against the destination field values so you can verify that patient names concatenate correctly, custom fields land on the right object, stage values map through the value-mapping table, and owner resolution resolves as expected. Approval of the sample diff is the gate for the full run.

  5. Execute full migration with delta-pickup window

    The full dataset runs against Twenty's REST API using batch inserts within the rate-limit window. A delta-pickup window (24–48 hours after the full run completes) captures any records created or modified in the source during the cutover window. FlitStack generates an audit log of every record operation and supports one-click rollback to the pre-migration snapshot if reconciliation finds discrepancies beyond the agreed tolerance threshold.

Most migrations complete in 48–72 hours of clock time for under 20,000 records. Larger datasets or complex custom-object setups extend to 7–10 days. The 20,000-record per-export cap in Twenty means datasets above that threshold require multi-pass extraction and API-based batch insertion rather than a single CSV upload. Pre-flight schema setup — creating custom objects and fields in Twenty — typically takes 1–2 days before the first record is loaded.
