Overview
Moving from Simpleview CRM to Twenty CRM is a transition from a vertical DMO platform to a horizontal open-source CRM. Simpleview structures data around Member Accounts, Listings, Coupons, Events, and DMO-specific pipelines for conventions, sports, and group business; Twenty uses a standard Company-Person-Opportunity model that must be extended with custom fields and custom objects to hold DMO-specific attributes. The biggest structural difference is that Simpleview's Custom_Account and Custom_Account_MS fields have no standardized schema across clients, so we extract every custom field definition during the audit phase and resolve each one individually against the destination before import begins. Amenity vocabularies on Listings are client-defined multi-select arrays that require deduplication and mapping to Twenty tags or picklists. The Simpleview Extranet partner portal, Cvent integration, and Momentus Elite sync have no equivalent in Twenty and must be rebuilt or replaced. We do not migrate Workflows, automations, or the Simpleview CMS native sync; we deliver a written inventory of these for the customer's admin to address post-migration.

Object mapping
Each row shows how a Simpleview CRM 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.
Simpleview CRM
Member Accounts
Twenty CRM
Company
1:1Member Accounts are the primary organizational object in Simpleview CRM, analogous to Companies in Twenty. Standard fields (name, address, contact info) map directly. Custom_Account fields (client-defined, non-multi-select) map to custom fields on the Twenty Company object. We extract the full Custom_Account field set during audit, create matching typed fields in Twenty Settings → Data Model before import, then import Member Account records as Company records. The Simpleview AcctID is preserved as a custom field sv_acctid__c for audit and cross-reference.
Simpleview CRM
Listings
Twenty CRM
Custom Object (Listing)
1:1Simpleview Listings represent partner/member entries in the directory and are tied to Member Accounts via AcctID. Listings have amenity arrays (Amenity_MS), category assignments, and coupon associations that have no direct Twenty standard object equivalent. We create a Listing custom object in Twenty with fields for amenity tags, category, listing URL, and the foreign key to the parent Company record. Amenity values from the client-defined vocabulary are deduplicated, mapped to Twenty Tags or a multi-select picklist, and any unmapped values are flagged for manual review before final import.
Simpleview CRM
Coupons
Twenty CRM
Note + Custom Fields
1:manyCoupons in Simpleview link to both ListingID and AcctID with date ranges (RedeemStart, RedeemEnd, PostStart, PostEnd) and HTML body text (OfferText). We map Coupon records to Note objects in Twenty linked to the target Company (via AcctID resolution), with custom fields for coupon code, validity dates, and category metadata. The OfferText HTML body is stored as Note body text. Coupon-to-listing associations are preserved as a custom relationship field on the Note pointing to the mapped Listing custom object.
Simpleview CRM
Events
Twenty CRM
Custom Object (Event)
1:1Simpleview Events are first-class objects with integrations to Cvent, Eventbooking, and Meetingmax. Event registrations link to Member Accounts. We create an Event custom object in Twenty with fields for event name, date range, venue, registration status, and a link to the primary Company (destination organization). Individual registrations migrate as child records via a registration sublist or as Note records attached to the Event, depending on registration field complexity. Event-to-attendee associations are sequenced after Company import so that the AcctID lookup resolves at migration time.
Simpleview CRM
Opportunities
Twenty CRM
Opportunity
1:1Simpleview CRM pipelines cover meetings, sports, travel trade, and group business with DMO-specific stages that vary by organization. Pipeline stages migrate as Opportunity Stage values in Twenty. Each Simpleview pipeline becomes a Twenty Opportunity with a custom stage field set to match the customer's current pipeline. We collect the customer's pipeline stage definitions during discovery and create the matching stage picklist in Twenty before migration. Closed-Won and Closed-Lost reasons map to custom Opportunity fields.
Simpleview CRM
Custom_Account_MS (Multi-Select)
Twenty CRM
Multi-Select Picklist or Tag
lossyMulti-select custom fields under Custom_Account_MS use a client-defined vocabulary and are often used for amenity classification, membership tier, or partner capability tagging. We extract the full vocabulary, deduplicate it, and map each value to either a Twenty multi-select picklist (if under 150 values) or a set of Tags (if over 150 unique values). Any unmapped vocabulary values are flagged in a review report before the final import batch runs.
Simpleview CRM
Attachments / Documents
Twenty CRM
Files
1:1Simpleview DAM handles digital assets stored against Member Accounts or Events. We extract file references and, where Simpleview API access permits, download files and re-upload them to Twenty as File records attached to the relevant Company, Listing, or Event record. If the Simpleview DAM is inaccessible via API (requires portal session), we extract the file reference URLs and deliver a file migration inventory for manual re-upload or a separate DAM migration engagement.
Simpleview CRM
Partner Portal Data (Extranet)
Twenty CRM
Company + Note
lossyThe Simpleview Extranet stores partner-submitted enrollment, co-op campaign signups, and online payments as action records rather than static data. We extract the underlying account and listing associations as Company records and Note entries capturing co-op campaign participation and enrollment status. The portal login credentials, session data, and enrollment workflows do not migrate; we document the Extranet feature set for the customer to assess against Twenty's access control capabilities or a replacement partner portal.
Simpleview CRM
Activity (Tasks, Notes, Events)
Twenty CRM
Task, Note, Event
1:1Simpleview CRM stores activity history against Member Accounts and Events including tasks, notes, and calendar entries. We map Simpleview activity records to Twenty Task (for action items), Note (for observations and call logs), and Event (for scheduled meetings) objects. Each activity record is linked to the parent Company record resolved via AcctID at migration time. We preserve the original Simpleview timestamp in the activity record for timeline ordering.
Simpleview CRM
Owner / User
Twenty CRM
WorkspaceMember
1:1Simpleview users assigned to records (account owner, opportunity owner, task assignee) map to Twenty WorkspaceMembers. We match by email address. Any Simpleview Owner without a matching Twenty user goes to a reconciliation queue; the customer provisions the missing WorkspaceMember before record import resumes. Inactive Simpleview users map to inactive Twenty members if historical assignment must be preserved.

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.
Simpleview CRM gotchas
Granicus acquisition introduces data residency and contract uncertainty
SOAP and XML (NVP) API requires client-specific credentials
Custom fields have no standardized schema across clients
Multi-select amenity arrays require vocabulary mapping
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
Discovery and API credential acquisition
We audit the Simpleview CRM instance across the authenticated org partition: Member Account count, Listings count, Event count, Opportunity volume, custom field definitions (Custom_Account and Custom_Account_MS), pipeline stage definitions, amenity vocabulary, and attachment references. We simultaneously coordinate with the customer's Simpleview PM to obtain production API credentials and confirm SOAP or XML-NVP transport. The discovery output is a written scope document, a client-specific field map, and a Simpleview API connectivity confirmation.
Twenty workspace preparation and schema deployment
We create the destination schema in Twenty: custom objects for Listing and Event, custom fields on Company and Opportunity for DMO-specific attributes, stage picklist values matching the Simpleview pipeline, and tag vocabulary for amenity values. Custom fields are created in Settings → Data Model before any CSV import runs. We invite all team members to the Twenty workspace so that owner lookups can resolve at migration time. The schema is validated in a staging pass before production migration begins.
Data extraction and transformation
We extract data from Simpleview in dependency order: Member Accounts first (the parent object), then Listings (with AcctID lookup), Events, Opportunities, Activities, and finally attachments. Custom_Account MS fields are extracted as arrays, deduplicated, and mapped to the target Twenty vocabulary. The Simpleview AcctID is preserved as a custom field on every target record for cross-reference. HTML in coupon OfferText fields is sanitized to plain text for Twenty Note compatibility.
Staging migration and reconciliation
We run a full migration into the Twenty production instance using the extracted data. The customer's RevOps lead reconciles record counts, spot-checks 20-40 records against the Simpleview source, and validates that Custom_Account field values populated correctly in Twenty. Any mapping corrections—wrong field type, missing picklist value, missed custom field—happen in the staging pass, not in production.
Production migration in dependency order
We run production migration in record-dependency order: Companies (from Member Accounts, with custom fields and preserved sv_acctid__c), Listings (custom object with Company lookup resolved), Events (custom object), Opportunities (with stage values matching the Simpleview pipeline), Activities (Task, Note, Event), and Files (where API access permits). Each phase emits a row-count reconciliation report before the next phase begins. Owner lookups resolve by email match against the pre-provisioned WorkspaceMember list.
Cutover, validation, and integration handoff
We freeze Simpleview write access during the cutover window, run a final delta migration of any records modified during the migration, then enable Twenty as the system of record. We deliver the locked-integration inventory (Cvent, Momentus Elite, Simpleview CMS, Extranet) to the customer's admin team with a rebuild recommendation for each. We support a three-day hypercare window for reconciliation issues. We do not rebuild Simpleview Workflows or automations in Twenty; that is a separate engagement documented in the integration handoff package.
