Overview
CRM.io by 500apps has no public API, no custom field support, and is actively shutting down as 500apps redirects customers to its new 500agents platform. Every migration from CRM.io runs through CSV export only, which flattens the relational structure between Contacts, Accounts, Deals, and Activities. We handle this by performing a full field-level review of every exported CSV, reconstructing Account-to-Deal links using a compound-key lookup table built from CRM.io's UI-based relationship view, and resolving Activity-to-Person associations through date and subject matching. Twenty CRM exposes a GraphQL API for data ingestion, giving us a structured path to load Contacts and Leads as People, Accounts as Companies, Deals as Opportunities with pipeline stage configuration, and Activities as the timeline events on each Person or Company record. We do not migrate Workflows, Automations, or Email Templates as they do not export via standard CSV. Document attachments require a separate binary transfer step; we flag this during scoping and provide two options. Because 500apps is in active wind-down, we treat every CRM.io migration as time-critical and advise against scheduling start dates beyond 60 days from the initial scoping call.

Object mapping
Each row shows how a CRM.io by 500apps 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.
CRM.io by 500apps
Contact
Twenty CRM
Person
1:1CRM.io Contact records (name, email, phone, company association) map 1:1 to Twenty CRM Person records. We extract the CSV export, normalize the name field into firstName and lastName, and ingest via Twenty's GraphQL mutations. The CRM.io company association (Account link) is preserved as a WorkspaceMember link or CompanyPersonRelation record in Twenty after the Company records are loaded. Email addresses serve as the dedupe key for Person records.
CRM.io by 500apps
Lead
Twenty CRM
Person (type = LEAD)
1:manyCRM.io Lead records (name, source, status, owner) map to Twenty CRM Person records with a type discriminator field set to LEAD. If Twenty's destination workspace uses the legacy Person model without type separation, Leads and Contacts merge into the same Person table using email as the dedupe key, with a source_system field set to CRM.io_Lead or CRM.io_Contact for audit. Lead status values from CRM.io (New, Contacted, Qualified, etc.) map to a custom picklist field in Twenty.
CRM.io by 500apps
Account
Twenty CRM
Company
1:1CRM.io Account records (business name, industry, size, address) map 1:1 to Twenty CRM Company records. We extract the Accounts CSV, map the industry and employee_count fields to their Twenty equivalents, and ingest Companies before any Person or Opportunity load to satisfy the required CompanyId lookup. Company domain from the address data is preserved for future enrichment.
CRM.io by 500apps
Deal
Twenty CRM
Opportunity
1:1CRM.io Deal records (stage, value, close date, owner, linked Account) map to Twenty CRM Opportunity records. The critical migration step is reconstructing the Account-to-Deal relationship from CRM.io's flat CSV export, which does not include the foreign key reference. We build a compound key from Deal name and associated Account name, cross-reference against the Account CSV export, and resolve the CompanyId in Twenty at migration time before Opportunity ingestion.
CRM.io by 500apps
Deal Stage / Pipeline
Twenty CRM
Opportunity Stage + Pipeline
lossyCRM.io's configurable pipeline stages export as stage names in the Deals CSV but there is no API to retrieve the active pipeline configuration or stage ordering. We infer stage order from deal record distribution and the customer's input during scoping, then configure Twenty's pipeline stages to match. Stage probability percentages are requested from the customer or inferred from stage names (e.g., Closed Won = 100%, Negotiation = 75%) and set as custom fields in Twenty.
CRM.io by 500apps
Activity (Call, Email, Task, Meeting)
Twenty CRM
TimelineEvent (Activity)
1:1CRM.io Activities (calls, emails, tasks, meetings) link to Contacts or Deals in the UI, but the parent object ID may not be reliably present in the CSV export. We reconstruct Activity-to-Person and Activity-to-Opportunity associations using a combination of date matching, subject text matching, and the owner email resolution. Each activity type from CRM.io maps to a Twenty TimelineEvent with the corresponding type discriminator (CALL, EMAIL, TASK, NOTE) and the original timestamp preserved for timeline ordering.
CRM.io by 500apps
Document
Twenty CRM
Attachment / File
1:1CRM.io Document Management stores file attachments with metadata (filename, type, associated record ID) in the CSV export, but binary file content does not export via standard CSV. We export the metadata and build an Attachment record in Twenty with a link to the original CRM.io file reference. For the binary files, we provide a separate bulk transfer via secure shared storage (preferred for large datasets) or manual re-upload instructions for the customer's admin team post-migration. This step is scoped separately from the core migration.
CRM.io by 500apps
Tag
Twenty CRM
Tag (array field)
lossyCRM.io exports Tags as comma-separated values within the Contact or Deal CSV rows. We parse these into an array field in Twenty, either as a native multi-select tag field if configured, or as a normalized Tag table with TagRelation records linked to the Person or Opportunity. The customer chooses the tag strategy during scoping.
CRM.io by 500apps
User / Owner
Twenty CRM
User
1:1CRM.io assigns record ownership to Users. We extract Owner names and emails from every record and map them to Twenty User accounts via a customer-provided lookup table during scoping. Any CRM.io Owner without a matching Twenty User is held in a reconciliation queue; the customer provisions the User in Twenty before record ingestion resumes.
CRM.io by 500apps
Email Template
Twenty CRM
(Not migrated)
1:1CRM.io Email Templates are UI-stored templates that do not export via standard CSV. We do not migrate Email Templates. Customers who need to preserve templates should manually export them from within the CRM.io UI before the wind-down date. We include a note in the scoping checklist to flag this for the customer's admin team.
CRM.io by 500apps
Custom Field
Twenty CRM
(No custom fields exist)
1:1CRM.io explicitly states 'Customization Possible: No'. There are no custom fields, custom objects, or extended schemas documented for the platform. The flat CRM.io schema is fully captured in the standard object exports above.

CRM.io by 500apps gotchas
No public API means all migrations are CSV-only
500apps wind-down creates migration urgency
No free trial makes pre-migration testing impossible
Review ecosystem is heavily skewed by incentivized reviews

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
Scoped CSV export and field inventory
We guide the customer's CRM.io admin through exporting every object (Contacts, Leads, Accounts, Deals, Activities, Documents metadata) from the CRM.io UI as CSV. We perform a field-level inventory of each exported file, identify missing foreign key columns, and build the relationship reconstruction plan using compound keys from the CRM.io UI's record view. We flag the Email Template and Document binary gaps at this stage. The output is a written Export Readiness Report with the relationship map and any data quality issues (missing values, encoding problems, date format inconsistencies) identified before transformation begins.
Twenty CRM schema setup and pipeline configuration
We configure Twenty CRM's target schema before any data loads. This includes setting up Company records with the industry and address fields matched to CRM.io Account fields, configuring the Person object with name and contact fields, defining Opportunity pipelines and stages to match the inferred CRM.io stage list, and creating any required custom fields for source-system audit trails (e.g., original_record_id from CRM.io). If the customer is using Twenty's new workspace model, we map CRM.io Account relationships to the appropriate workspace structure. Schema setup is validated in Twenty's UI before the first data load.
Test migration with representative sample
We run a test migration using a representative sample of 50-100 records from each object (Contacts, Leads, Accounts, Deals, Activities) to validate the mapping, relationship reconstruction logic, and data quality in Twenty CRM. The customer's admin reviews the output in Twenty, spot-checks records against the source CRM.io data, and approves or flags corrections. Any mapping corrections, field value transformations, or pipeline stage adjustments are made before the full production migration begins. This step also validates that Twenty User accounts are provisioned for all CRM.io Owners identified in the Owner reconciliation pass.
Company and Person bulk ingestion via GraphQL API
We ingest the full dataset in dependency order using Twenty's GraphQL API. Accounts (as Companies) load first with no dependencies. Persons (Contacts and Leads merged or separated per the scoping decision) load second with CompanyId resolved from the lookup table built during the export phase. CRM.io Owner names are resolved to Twenty User IDs via the customer-provided lookup table. We use batch GraphQL mutations with chunking and error tracking to handle large record volumes. Each phase emits a row-count reconciliation report.
Opportunity ingestion with relationship reconstruction
Deals load as Opportunities in Twenty CRM with the CompanyId (Account reference) resolved through the compound-key lookup table built from CRM.io's record relationship view. Pipeline stages are set from the configured stage mapping. Close dates, deal values, and owner assignments migrate directly. After Opportunity ingestion, we run the Activity timeline load — calls, emails, tasks, and meetings from CRM.io map to Twenty TimelineEvents linked to the resolved Person or Opportunity records using date and subject matching for association reconstruction.
Cutover, delta sync, and automation handoff
We freeze CRM.io writes during cutover, run a final delta migration of any records created or modified during the migration window, then mark Twenty CRM as the system of record. We deliver the Written Automation Inventory documenting every CRM.io workflow, sequence, and automation requiring rebuild in Twenty (or a separate workflow tool if the customer chooses). We do not rebuild automations as part of the migration scope. Document binary transfer proceeds in parallel if the customer selected that option. We support a one-week hypercare window for reconciliation issues raised by the customer's team.
