Overview
Moving from Access CRM to Twenty CRM is a migration from a UK mid-market suite-embedded CRM to an open-source platform with full data ownership and a documented import API. Access CRM is typically deployed alongside Access Pay & Bill, Access Elite, and Servelec care modules; records in Access CRM may carry cross-module references that have no equivalent in a standalone CRM. We flag every external reference during scoping, strip the link, and create stub records or preserve the ID in a custom field so relationships do not silently break. Pipeline stage names are free-text in Access CRM and vary between tenants; we capture the full stage list and produce a mapping matrix before records are touched. Knowledge-base articles and self-service portal content have no standard CRM export path; we deliver them as a structured HTML or JSON export package alongside the CRM migration rather than as CRM objects. Twenty's self-hosting model ($9-$19 per user per month for cloud; free aside from hosting costs for self-hosted) removes per-contact and per-module pricing surprises that come with Access Group suite contracts.

Object mapping
Each row shows how a Access 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.
Access CRM
Contact
Twenty CRM
People
1:1Access CRM Contacts map directly to Twenty CRM People. Name, email, phone, address, and owner assignment migrate as standard fields. We resolve the Access CRM owner reference by email against Twenty CRM workspace Members and create placeholder Person records for any owner without a matching Twenty user.
Access CRM
Company
Twenty CRM
Company
1:1Access CRM Company records map to Twenty CRM Company. The organisation-level data (name, domain, industry, employee count, address) migrates directly. Parent-child hierarchy in Access CRM migrates as a flat organisation tree in Twenty, and we flag any circular references during the scoping audit so they do not cause import loops.
Access CRM
Opportunity
Twenty CRM
Opportunity
1:1Access CRM Opportunities carry Worst/Likely/Best monetary values and stage-based probability logic. These map to Twenty CRM Opportunities, but the three-value probability model has no native equivalent in Twenty. We preserve Worst/Likely/Best as custom Opportunity fields and set the primary Opportunity amount to the Likely value unless the customer specifies otherwise during scoping.
Access CRM
Pipeline
Twenty CRM
Opportunity Pipeline (configured)
lossyAccess CRM Kanban pipelines with tenant-defined stage names require explicit mapping to Twenty CRM pipeline configuration. We capture every distinct stage name during scoping, produce a stage-mapping matrix, and configure the Twenty pipeline stages before any records are imported. Stages with no mapping direction default to an Archive pipeline unless the customer explicitly directs otherwise.
Access CRM
Case
Twenty CRM
Custom Object (Case)
1:1Access CRM Cases (problem-tracking with open-through-resolution lifecycle) do not have a native equivalent in Twenty CRM. We create a Case custom object in Twenty during schema setup, define custom fields for status, priority, owner, and description, and map the Access CRM case lifecycle to the custom object's status field. If the customer also uses Twenty's task and note objects for tracking, Cases can alternatively be modelled as Opportunities with a specific record type.
Access CRM
Activity (Calls, Emails, Meetings, Tasks)
Twenty CRM
Task or Note
1:1Access CRM Activities associated with Contacts and Opportunities migrate as Task records or Note records in Twenty CRM. Call disposition and duration migrate to custom Task fields. Meeting start and end times, location, and attendees map to the corresponding Task fields. The original timestamp is preserved on the ActivityDate field so the timeline ordering is intact in Twenty.
Access CRM
Custom Fields
Twenty CRM
Custom Fields (via Settings → Data Model)
1:1Access CRM tenant-specific custom fields are extracted via the admin knowledge base and cross-referenced against the full field manifest. Each custom field is pre-created in Twenty CRM Settings → Data Model with the appropriate type (text, number, date, select, multi-select, relation) before any records are imported. Fields that reference Access-specific picklist values are normalised to text or select fields in Twenty as appropriate.
Access CRM
Web Enquiry Form Fields
Twenty CRM
Custom Object (Enquiry) or custom fields on People
1:manyAccess CRM web-enquiry forms feed leads into Opportunities or raw lead records. Form field structures are configurable per tenant. We treat each form as a custom object set or as additional custom fields on the People object depending on the form's complexity, and map the enquiry source and field data accordingly. The customer chooses the modelling approach during scoping.
Access CRM
User (Owner)
Twenty CRM
Workspace Member
1:1Access CRM User records (name, email, role) are migratable. We map the Access CRM owner/User assignment on each Contact, Company, Opportunity, and Activity to the corresponding workspace Member in Twenty by email match. Users without a matching Twenty workspace Member are held in a reconciliation queue for the customer's admin to provision before the record import phase begins.
Access CRM
Knowledge Base Articles
Twenty CRM
No native CRM object (separate export package)
1:1Access CRM knowledge-base articles and customer self-service portal content have no standard counterpart in Twenty CRM. We export KB content as a structured HTML or JSON package and deliver it alongside the CRM record migration so the customer can re-import to their chosen knowledge-base platform (Twenty does not include a native KB module). We do not map KB articles to any Twenty CRM object.
Access CRM
Cross-module References (Access Pay & Bill, Access Elite, Servelec)
Twenty CRM
Stub records or stripped references
lossyAccess CRM records may carry references to workers, clients, or care episodes in Access Pay & Bill, Access Elite, or Servelec. These cross-module IDs cannot be imported into Twenty CRM. We flag every external Access module reference during the scoping audit, preserve the original module and ID in a custom text field on the affected record, and either create a stub record or strip the reference depending on the customer's preference documented during scoping.

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.
Access CRM gotchas
Cross-module references require pre-migration audit
Pipeline stage names are tenant-defined free text
Knowledge-base articles have no standard CRM export path
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 Access Group reference audit
We conduct a scoping call with the customer's Access CRM administrator to enumerate the full record inventory: Contacts, Companies, Opportunities, Cases, Activities, custom fields, pipeline configurations, and web-enquiry forms. We explicitly audit for cross-module references to Access Pay & Bill, Access Elite, and Servelec, flagging every record that carries an external module ID. We also request access to the admin knowledge base for field manifest extraction and confirm the customer's export capability. The discovery output is a written migration scope document, a cross-module reference inventory, and an export preparation checklist for the customer's Access CRM admin.
Schema design and Twenty workspace preparation
We set up the Twenty CRM workspace before any data moves. This includes creating any custom objects (Case, custom field sets for Worst/Likely/Best deal values, Access module reference fields), configuring pipeline stages per the stage-mapping matrix produced in discovery, setting up workspace Members (invited before import so owner Lookups resolve), and configuring the workspace's country, timezone, and currency settings. Schema is validated in Twenty's sandbox or a trial workspace before the production migration begins.
Data export, cleaning, and format preparation
We coordinate with the customer's Access CRM administrator to extract data in CSV format using the internal reporting tools. We clean the exported data: removing duplicates (Contacts with identical email addresses, Companies with identical names), removing outdated records (Contacts with no activity in two or more years per Twenty's migration guidance), formatting phone numbers, normalising picklist values, and removing Access module cross-references from fields that will not accept them. We produce a cleaned CSV package for each object type, in import order (Companies first, then People, then Opportunities, then Cases, then Activities), and flag any records that cannot be resolved for the customer's admin to address.
KB article export and helpdesk packaging
We export Access CRM knowledge-base articles and customer self-service portal content as a structured HTML or JSON package. The export includes article title, body content, categories, and any metadata. We deliver the KB package separately from the CRM record migration, with a field mapping guide for the customer's admin to use when re-importing to their chosen knowledge-base platform. We do not map KB articles to any Twenty CRM object because Twenty does not include a native knowledge-base module.
Production migration in dependency order
We run the production migration in record-dependency order: workspace Members (pre-provisioned and validated), Companies (from Access CRM Companies), People (with company relations resolved), Opportunities (with pipeline, stage, and owner Lookups resolved), Cases (custom object), and Activities (Tasks and Notes). Each phase emits a row-count reconciliation report before the next phase begins. Cross-module Access references are stripped and the original module and ID are preserved in the custom accessModuleReference field. KB articles are delivered as a separate export package at the same time as the CRM migration.
Cutover, validation, and handoff
We freeze Access CRM writes during cutover, run a final delta migration of any records modified during the migration window, then hand over to the customer's team as the system of record. We deliver the pipeline stage-mapping matrix, the cross-module reference inventory (with original IDs preserved in the accessModuleReference field), the KB export package with re-import guide, and a list of any records that could not be fully resolved for manual review. We support a one-week hypercare window for reconciliation issues. Workflow rebuild inventory, pipeline reconfiguration, and any KB re-import work are outside the standard migration scope and are handled by the customer's admin team or a separate engagement.
