Overview

What this migration involves

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.

Leaving

Access CRM

What's pushing teams away

  • Performance issues emerge at scale — G2 reviewers note that the platform has limited features and slows noticeably as record counts grow, particularly on the CRM-for-customer-service module.
  • Organisations seeking to exit the Access ecosystem report that tight coupling to Access Pay & Bill and Access Elite creates data-lock-in that makes migration complex and costly.
  • Limited third-party integration ecosystem compared to HubSpot or Salesforce means teams needing best-of-breed tooling eventually consolidate onto platforms with richer marketplace apps.
  • The platform lacks the AI and automation depth that modern sales teams expect from a 2025-era CRM, prompting churn to competitors with built-in AI deal coaching and generative workflows.

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 Access CRM objects map to Twenty CRM

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

maps to

Twenty CRM

People

1:1
Fully supported

Access 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

maps to

Twenty CRM

Company

1:1
Fully supported

Access 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

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Access 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

maps to

Twenty CRM

Opportunity Pipeline (configured)

lossy
Fully supported

Access 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

maps to

Twenty CRM

Custom Object (Case)

1:1
Fully supported

Access 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)

maps to

Twenty CRM

Task or Note

1:1
Fully supported

Access 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

maps to

Twenty CRM

Custom Fields (via Settings → Data Model)

1:1
Mapping required

Access 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

maps to

Twenty CRM

Custom Object (Enquiry) or custom fields on People

1:many
Fully supported

Access 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)

maps to

Twenty CRM

Workspace Member

1:1
Fully supported

Access 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

maps to

Twenty CRM

No native CRM object (separate export package)

1:1
Not supported

Access 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)

maps to

Twenty CRM

Stub records or stripped references

lossy
Fully supported

Access 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.

Pair-specific challenges

  • Sparse Access CRM export tooling forces manual scoping

    Access CRM does not publish a bulk-export API or a self-service data export feature in its public admin documentation. We prepare exports by working through the admin knowledge base, extracting field manifests, and coordinating with the customer's Access CRM administrator to generate CSV exports from the internal reporting tools. If the customer lacks an internal export capability or the exports are incomplete, the scoping phase extends by one to two weeks while we design a manual extraction approach or coordinate with The Access Group's support team. We flag this constraint during the first discovery call so it does not delay the migration start date.

  • Cross-module Access Group references break silently without audit

    Access CRM is typically deployed alongside Access Pay & Bill, Access Elite, and Servelec care-management modules. Records in Access CRM may carry IDs referencing workers, clients, or care episodes that live in those sister systems. These cross-module IDs have no counterpart in Twenty CRM. If we do not audit and resolve every external reference during scoping, the IDs import as orphaned strings on records with no resolution path. We flag every reference to external Access modules in the scoping audit report, strip the live reference, and preserve the module name and original ID in a custom text field on the affected record for the customer's admin to review post-migration.

  • Knowledge-base articles require a separate export package

    Access CRM's knowledge-base articles and customer self-service portal content are content objects that do not have a standard counterpart in Twenty CRM's data model. Twenty does not include a native knowledge-base module. We export KB content as a structured HTML or JSON package and deliver it alongside the CRM record migration. The customer re-imports the KB package into their chosen knowledge-base platform (Notion, Guru, Zendesk, Confluence, or a custom solution) post-migration. We do not map KB articles to Twenty CRM objects because no such object exists natively.

  • Tenant-defined pipeline stage names require explicit mapping before import

    Access CRM does not enforce a standard pipeline stage vocabulary. Each tenant defines stages like Proposal, Negotiation, WON, Closed-Lost-Ghost, or entirely custom labels. Twenty CRM stages are configurable but require explicit definition in the workspace settings before records can be imported. We capture the full stage list during scoping, produce a stage-mapping matrix, and configure the Twenty pipeline before any records are touched. Stages without a defined mapping direction default to an Archive pipeline in Twenty unless the customer explicitly directs otherwise. Without this step, import jobs fail or records land in an unintended stage on first attempt.

Migration approach

Six steps for a successful Access CRM to Twenty CRM data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  • MCP server and webhooks shipped as standard features, not premium upgrades.
  • Modern PostgreSQL-backed data model that developer teams can query, extend, and self-host.

Weaknesses

  • Recent v1.0 release means limited production hardening compared to CRMs with multi-year operational track records.
  • No native email sequencing or sales engagement tools — follow-up cadences require a separate platform.
  • No native two-way email sync or inbox integration, requiring third-party connectors for full activity logging.
  • Self-hosting 'free' pricing hides real infrastructure and DevOps costs that stack up over time.
  • Workflow automation is functional but lacks the complexity needed for sophisticated multi-step sales motions.

Most migrations land between two and four weeks for organisations with up to 15,000 Contacts, 3,000 Companies, and 2,000 Opportunities, where the Access CRM export is available without manual extraction support. Migrations with cross-module Access Group references (Access Pay & Bill, Access Elite, Servelec), large KB article collections (over 500 articles), non-standard pipeline stage configurations, or tenant-specific custom fields that require extensive mapping extend to six to ten weeks. The Access CRM export tooling constraint (no documented bulk-export API) can add one to two weeks to the scoping phase if manual export coordination is required.
