Overview
BoomTown is a real estate SaaS platform bundling CRM, IDX websites, and lead-generation services under 12-month contracts that commonly run $1,000–$1,750 per month. For small teams paying that price, the value proposition collapses fast — especially when the bundled IDX site and lead-gen tools aren't needed. Twenty CRM is an open-source CRM built on TypeScript, NestJS, React, and PostgreSQL, offering the same contact, company, and deal management at $9 per user per month with a full REST and GraphQL API. The migration carries everything BoomTown stores natively — People (contacts), Companies, Opportunities (deals), Notes, Tasks, and any custom objects — into Twenty's object model. The harder problems are mapping BoomTown's deal stage values to Twenty's opportunity stage pick-list, preserving owner assignments via email match, handling BoomTown's drip campaign and lead-routing logic (which has no Twenty equivalent), and sequencing the import so Twenty's foreign-key requirements are satisfied: Companies first, then People (linked by companyId), then Opportunities. We export BoomTown data via their API V2, transform to Twenty's CSV import format or batch-post via the GraphQL API, run a sample migration with field-level diff, then execute the full run with a 24–48 hour delta-pickup window for any in-flight changes. Workflows, sequences, drip campaigns, and IDX website configurations do not migrate — they require manual rebuild in Twenty.

Object mapping
Each row shows how a BoomTown 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.
BoomTown
Contact
Twenty CRM
Person
1:1BoomTown contacts map 1:1 to Twenty's People object. Every contact must link to a Company record (companyId foreign key) — contacts without a primary company receive a default 'Unassigned' company record created during migration so the relation is valid in Twenty.
BoomTown
Company
Twenty CRM
Company
1:1BoomTown companies map directly to Twenty's Companies object. Parent-child company hierarchies and subsidiary relationships are preserved via Twenty's self-referential companyId relation field. It is critical that Companies import before People so that the companyId foreign key lookup resolves correctly when contacts are created during migration. Any orphaned company references are flagged and resolved before the People batch begins.
BoomTown
Deal
Twenty CRM
Opportunity
1:1BoomTown deals map to Twenty's Opportunities object. Each deal's stage name maps to a Twenty opportunity stage pick-list value — if BoomTown uses custom stage names, value-by-value mapping is required before import. Close dates, amounts, and owners carry over as-is.
BoomTown
Pipeline Stage
Twenty CRM
Opportunity Stage
1:1BoomTown pipeline stage names are pick-list values that require explicit value mapping to Twenty's opportunityStage field. Stage order and probability weights are re-applied in Twenty after mapping. HubSpot-style multi-pipeline setups collapse to one Twenty pipeline unless custom fields are used to simulate pipeline branching.
BoomTown
User / Owner
Twenty CRM
WorkspaceMember
1:1BoomTown owner IDs resolve to Twenty WorkspaceMembers by email match. All Twenty users must accept their invite before import — otherwise owner assignments fail and records land with an unassigned owner. We flag unmatched owners before migration and let you assign a fallback owner.
BoomTown
Activity (Call, Email, Meeting, Note)
Twenty CRM
Task / Note
1:1BoomTown call logs, email records, meetings, and notes migrate as Twenty Tasks and Notes. Tasks inherit the original timestamp and the owner who created the activity in BoomTown. The activity type (call, email, meeting) is stored as a custom select field on the Task for filtering.
BoomTown
Drip Campaign / Sequence
Twenty CRM
N/A
1:1BoomTown drip campaigns and sequences have no native equivalent in Twenty's current workflow builder. We export the drip campaign definitions (stage triggers, delay days, content) as a structured JSON reference file. Rebuild in Twenty's workflow builder or an external sequencing tool using this file as a specification.
BoomTown
Lead Routing / Assignment Rules
Twenty CRM
N/A
1:1BoomTown lead assignment rules (geo-routing, round-robin, team-based) do not have a direct mapping. We export the rule logic as a configuration document. Twenty's workflow automations can replicate assignment logic — your admin rebuilds these using Twenty's Conditions and Actions with guidance from the exported rules.
BoomTown
Custom Object (e.g., Listing, Transaction)
Twenty CRM
Custom Object
1:1BoomTown real estate custom objects (listings, transactions) map to Twenty custom objects created during migration planning. BoomTown N:N relationships between custom objects require a junction custom object in Twenty to maintain the association structure. We document the required schema before creating the custom object in Twenty.
BoomTown
IDX Website / Property Listing
Twenty CRM
Custom Object or Attachment
1:1BoomTown's IDX website data and property listings are real estate-specific objects without a Twenty equivalent. We migrate listing data as a custom object with fields for address, MLS ID, status, and price. Property images re-upload as file attachments linked to the listing record.
BoomTown
Lead Score / Predictive Score
Twenty CRM
Custom Field (Number)
1:1BoomTown's predictive lead scoring (behavioral activity-based) migrates as a custom Number field on the Person object. The scoring algorithm itself — which is BoomTown-proprietary — does not replicate; only the last-known score value transfers as a static number for reference.
BoomTown
Transaction / Contract
Twenty CRM
Custom Object
1:1BoomTown transaction records including deal-related contracts and e-signatures migrate as a Twenty custom object linked to the relevant Opportunity via a custom relation field. Transaction status, involved parties, key dates (execution, closing, expiration), and monetary values become custom fields on the custom object. E-signature documents and supporting contract files re-upload as file attachments on the transaction record after migration.

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.
BoomTown gotchas
Export requires Broker or Admin permission
Workflows and automations do not export
12-month contract creates financial lock-in
IDX website content is not migratable via API
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 BoomTown data model and owner roster
We connect to BoomTown via API V2 to extract all standard objects (People, Companies, Opportunities, Tasks, Notes) and any custom objects (listings, transactions). We simultaneously audit the owner and user list, matching each BoomTown owner email to a prospective Twenty WorkspaceMember. Any owner without a corresponding Twenty user is flagged; your team creates and sends invites before migration day so all owners are active. We also export drip campaign definitions, lead-routing rules, and IDX configuration as rebuild reference documents.
Create Twenty workspace schema
Before data moves, we create all required custom fields in Twenty's Settings → Data Model: Lifecycle_Stage__c, Pipeline__c, Task_Type__c, Original_Create_Date__c, Source_System_ID__c, Lead_Score__c, and any custom fields for listing and transaction objects. We also create the Listing and Transaction custom objects with their required fields and relation schemas. This step runs in parallel with the BoomTown export so the destination schema is ready when the import sequence begins.
Run sample migration with field-level diff
A representative slice of BoomTown data — typically 100 to 500 records spanning People, Companies, Opportunities, and a sample custom object — migrates first. We generate a field-level diff report comparing source values against Twenty records, verifying stage mapping, owner resolution, companyId links, and date preservation. You review the diff and approve field mapping before the full run commits. Any value-mapping gaps or custom field misconfigurations surface here, not in production.
Execute full migration with ordered import sequence
The full migration runs in the required Twenty import order: Companies first, then People (with companyId links resolved), then custom objects, then Opportunities (with companyId and personId links resolved), then Tasks and Notes. Each batch is validated before the next begins. Our migration tool handles email-to-WorkspaceMember resolution, stage value mapping, and custom field population. We monitor import success rates and pause to investigate any batch exceeding a 2% error threshold.
Delta pickup and cutover validation
After the full migration completes, we open a 24–48 hour delta-pickup window that captures any records created or modified in BoomTown during the cutover period. Your team continues working in BoomTown through this window. After delta records land in Twenty, we run a final reconciliation report comparing record counts and field totals against the BoomTown export snapshot. An audit log captures every operation; one-click rollback is available if reconciliation fails materially.
