Overview

What this migration involves

Moving from Accelo to Twenty CRM is a scope reduction, not a lateral move. Accelo bundles professional services automation — CRM, project delivery (Jobs), ticketing, time tracking, and native billing with retainers — into a single platform. Twenty CRM is a focused open-source CRM built for contact management, deal tracking, and activity logging, with an API-first architecture that supports custom objects via GraphQL metadata endpoints. The migration preserves Companies, Contacts, and Deals as direct one-to-one maps, but Jobs become either a custom Project object or a Notes-and-Tasks structure, Retainers become Contracts with custom fields, and Time Entries and Invoices have no native destination. We deliver a written inventory of every Accelo Workflow and Trigger that requires manual rebuild in Twenty's settings, and we do not migrate billing configurations because Twenty has no native billing engine.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Accelo

What's pushing teams away

  • The platform is described as glitchy — streams disappear after submission, task start times behave unpredictably, and the infrastructure requires frequent refreshes to reflect changes.
  • The learning curve is steep: navigating job boards, distinguishing Jobs from Lists, and integrating Accelo into existing processes is difficult, especially for non-technical team members.
  • Implementation timelines range from 4–12 weeks depending on data migration complexity, integration requirements, and team size — longer than comparable PSA tools.
  • Per-user pricing with mandatory minimums of 3–5 seats inflates costs for smaller teams, and opaque custom-quote pricing for larger deployments makes budgeting difficult.
  • Performance and reporting limitations noted across user reviews suggest the platform may not scale well for larger professional services operations with high data volumes.

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 Accelo objects map to Twenty CRM

Each row shows how a Accelo 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.

Accelo

Companies

maps to

Twenty CRM

Company

1:1
Fully supported

Accelo Companies export via /affairs with full custom field support. Map directly to Twenty Company object. The company name becomes Company.displayName, address maps to the Company address fields, and industry maps to a custom picklist field if Twenty's industry field is not configured. Company-to-contact relationships resolve during the Contact import phase.

Accelo

Contacts

maps to

Twenty CRM

People

1:1
Fully supported

Accelo Contacts export via /contacts with first name, surname, email, phone, and custom fields. Map to Twenty People object. Contact-to-company links resolve via the Company mapping, attaching each People record to the correct Company via the Twenty relationship field. Email deduplication runs against the People.email field before insert.

Accelo

Deals (Sales Pipeline)

maps to

Twenty CRM

Opportunity

1:1
Mapping required

Accelo Deals export via the Sales API and map to Twenty Opportunity. We preserve deal value, stage name, owner assignment, and custom fields. Accelo Deal stages map to Twenty Opportunity stage values, which we configure during workspace setup. Closed-won and closed-lost states and dates migrate as custom fields if the standard schema does not include them.

Accelo

Jobs

maps to

Twenty CRM

Custom Object (Project)

lossy
Fully supported

Accelo Jobs have no native Twenty equivalent. We create a Project custom object via Twenty's /metadata API with fields for title, description, status, start date, due date, assigned user, and related company. Phases within a Job map to sub-tasks or a Phase custom field. The customer chooses whether to migrate open Jobs only or include historical completed Jobs based on business value.

Accelo

Tasks

maps to

Twenty CRM

Task

1:1
Mapping required

Accelo Tasks export from /tasks with assignees, checklists, due dates, and custom fields. Checklist items within tasks preserve as sub-task rows. Task statuses map to Twenty Task status values configured during workspace setup. Tasks linked to Jobs resolve to the Project custom object created during Jobs migration.

Accelo

Tickets

maps to

Twenty CRM

Custom Object (Support Ticket)

lossy
Fully supported

Accelo Tickets have no native Twenty equivalent. We create a Support Ticket custom object with fields for subject, description, status, priority, type, assignee, and related company or contact. Ticket conversations and comments migrate as Note records attached to the custom Ticket object. Custom ticket fields map to custom fields on the Ticket custom object.

Accelo

Time Entries

maps to

Twenty CRM

Custom Object (Time Entry)

lossy
Mapping required

Accelo Time Entries have no native Twenty equivalent. We create a TimeEntry custom object with fields for hours, billable flag, rate, date, related task or job, and staff member. Billable/non-billable status preserves as a boolean field. We flag Time Entries that reference archived Jobs or Retainers for the customer to review before migration.

Accelo

Staff (Users)

maps to

Twenty CRM

WorkspaceMember / User

1:1
Mapping required

Accelo Staff records export via /staff and map to Twenty WorkspaceMember. Accelo distinguishes Staff (delivery users) from broader User records. We resolve by email match and flag any Staff without a matching Twenty workspace for admin provisioning before record import.

Accelo

Leads

maps to

Twenty CRM

People or Opportunity

lossy
Mapping required

Accelo Leads export via the Sales API with source, status, owner, and custom fields. Depending on whether the customer treats Leads as prospects or unqualified Deals, we map to Twenty People (with a lead status custom field) or to Opportunity records without a company association. The customer decides during scoping.

Accelo

Invoices

maps to

Twenty CRM

Custom Object (Invoice Record) or excluded

lossy
Mapping required

Accelo Invoices carry financial data including line items, amounts, and status. Twenty has no native billing engine. We create an Invoice Record custom object to preserve historical invoice data as read-only records, but the customer must use a separate invoicing tool post-migration. We flag any Invoice records that reference retired chart-of-accounts entries during scoping.

Accelo

Retainers

maps to

Twenty CRM

Custom Object (Contract)

lossy
Mapping required

Accelo Retainers combine contract terms, prepaid balance, and billing rules. We separate Retainer metadata (contract dates, client, value) into a Contract custom object in Twenty. Prepaid balance and billing rules have no Twenty equivalent; we preserve the balance as a custom field and flag the gap for the customer's admin. Accelo Payments fee structure (3.4% card fee plus $0.20) does not migrate.

Accelo

Attachments

maps to

Twenty CRM

Attachments via File API

1:1
Mapping required

Attachments on Jobs, Tasks, and Tickets export via /attachments. File content fetches individually. We download and re-upload to Twenty's file storage, preserving filename and linked object association. File type and size validation runs against Twenty's supported formats before upload.

Pair-specific challenges

  • Accelo Jobs, Tickets, and billing have no native Twenty destination

    Accelo's full PSA stack includes Jobs (projects), Tickets (support), Retainers (prepaid billing), Invoices, and Time Entries. Twenty CRM has no native equivalents for any of these. We handle this by creating custom objects via Twenty's /metadata API for Projects, Support Tickets, Time Entries, Contracts (Retainers), and Invoice Records, but the billing logic (rate calculations, prepaid balance consumption, invoice generation) cannot migrate. The customer must implement a separate invoicing tool — Twenty documents recommend external tools for billing. We flag every Retainer balance and Invoice record that references retired financial entries during scoping so the customer can make a retention decision before migration runs.

  • Accelo custom fields on Jobs, Tasks, and Tickets are not accessible via API

    Accelo's public API supports custom fields for Companies and Contacts only. Custom fields on Tasks, Jobs, Tickets, and other objects require access through Accelo's proprietary configuration and are not exposed via the documented /api/v0 endpoints. We identify these custom fields during discovery scoping, but the migration cannot retrieve their values through the API. Options include CSV export from the Accelo UI (which bypasses the API limitation) or flagging these fields for manual post-migration entry. We document every affected field and its approximate record count so the customer can estimate manual entry effort.

  • Accelo has no bulk export API — pagination required for all object reads

    Accelo's REST API exposes individual record endpoints with no bulk export or batch read mechanism. For migrations involving thousands of Jobs, Tasks, or Time Entries, we paginate through the API which increases migration time and API call volume. We mitigate this by requesting datasets in manageable pages, scheduling migration windows during off-peak hours to avoid throttling, and using incremental sync where the API supports modified-since filters. Migrations with large time entry histories or high task counts should expect extended API iteration phases.

  • Twenty custom objects require schema creation before data import

    Twenty's /metadata API creates custom object schemas before any data import. The CSV import feature in Twenty creates records, not fields or objects. We pre-create every required custom object (Project, Support Ticket, TimeEntry, Contract, Invoice Record) and their custom fields via the /metadata API before migration begins. This adds a schema-design phase to the migration timeline that does not exist when migrating between two platforms with aligned object models. The customer reviews and approves the custom object schema during scoping before we deploy it to the Twenty workspace.

  • Accelo UI instability can affect migration scoping accuracy

    Multiple G2 reviews report Accelo UI instability: streams disappearing after submission, task start times not applying correctly, and refresh cycles required to see updated data. This does not corrupt underlying data but can make it harder for customers to manually verify record counts or statuses during migration scoping calls. We bypass this by capturing all scoping data via the Accelo API rather than UI exports, ensuring the record counts we present to the customer reflect the authoritative API data rather than display-state artifacts.

Migration approach

Six steps for a successful Accelo to Twenty CRM data migration

  1. Discovery and custom object schema design

    We audit the Accelo account across all modules: Companies, Contacts, Deals, Jobs, Tasks, Tickets, Time Entries, Staff, Invoices, and Retainers. We identify custom fields (distinguishing API-accessible Company and Contact custom fields from API-inaccessible Job and Ticket custom fields), record counts per object, and the status distribution of open versus archived records. We pair this with a Twenty workspace audit to confirm the hosted or self-hosted deployment type. The discovery output is a written migration scope with the custom object schema design for Twenty — including every custom object, field, and picklist value that needs to be created before data import.

  2. Twenty workspace preparation and custom object deployment

    We deploy the custom object schema to the Twenty workspace via the /metadata API before any data migration begins. This includes creating the Project, Support Ticket, TimeEntry, Contract, and Invoice Record custom objects with all required fields, picklists, and relationships. Twenty's GraphQL schema updates automatically after metadata changes. We validate the schema by querying each custom object via /graphql to confirm the fields exist before proceeding to data migration. This phase cannot be skipped because Twenty's CSV import only creates records, not schema.

  3. Sandbox migration and record-count reconciliation

    We run a full migration into a staging environment using production-like data volume. The customer reviews the migrated Companies, Contacts, Deals, and custom object records in Twenty and validates record counts against the Accelo source. We provide a reconciliation report showing object-level counts before and after migration, and the customer signs off before production migration begins. Any mapping corrections, custom field additions, or object schema adjustments happen at this stage.

  4. Owner and user reconciliation

    We extract every distinct Accelo Staff member referenced on Companies, Contacts, Deals, Tasks, Jobs, and Tickets and match by email against the Twenty workspace's user list. Staff without matching Twenty users go to a reconciliation queue. The customer's Twenty admin provisions any missing workspace members. This step gates the migration because OwnerId and assigneeId references must resolve before record insert. We do not migrate Accelo user permissions or roles as Twenty's permission model operates differently.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Company records first (no dependencies), then People (with CompanyId resolved), then Opportunities (with CompanyId and UserId resolved), then the Project custom object (with related Company and User references), then Tasks, then the Support Ticket and TimeEntry custom objects, then Contracts and Invoice Records. Attachments download and re-upload after their parent records exist. Each phase emits a reconciliation count before the next phase begins. We run a delta pass at cutover to migrate any records modified during the migration window.

  6. Cutover, validation, and manual-rebuild handoff

    We freeze Accelo writes during cutover, run the final delta migration, and mark Twenty as the system of record. We deliver a written inventory of every Accelo Workflow, Trigger, and Automation requiring manual rebuild in Twenty's settings — Twenty does not have a native workflow migration path. We do not rebuild Accelo Retainer billing logic or Invoice generation in Twenty because Twenty has no native billing engine. We support a one-week hypercare window for reconciliation issues. Post-migration admin configuration, user training, and workflow rebuild are outside standard scope and constitute a separate engagement.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • Unified platform combining CRM, project delivery, time tracking, and billing without separate integrations.
  • Client portal enables external collaboration, quote approvals, and invoice viewing without email.
  • Pre-built workflow automations for professional services reduce configuration effort compared to general PM tools.
  • Native billing engine with retainer management, invoicing, and payment processing built into the core platform.
  • High G2 user adoption ratings for project management and resource management categories.

Weaknesses

  • Glitchy UI with stream disappearing, task timing bugs, and unreliable refresh behavior reported across reviews.
  • Steep learning curve: navigating job boards, distinguishing Jobs from Lists, and integrating into existing processes takes time.
  • Per-user pricing with opaque enterprise quotes and 3–5 seat minimums makes small team adoption expensive.
  • Performance and reporting limitations noted in user feedback suggest scalability constraints for larger operations.
  • Paid customer support and inconsistent service quality reported in negative reviews.

Strengths

  • AGPL-3.0 open-source license with full source code on GitHub — no vendor lock-in, no sunset risk.
  • Unlimited users and unlimited custom objects on self-hosted, with no feature gating based on headcount.
  • REST and GraphQL APIs available on all paid tiers, not locked behind an enterprise add-on fee.
  • 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.

Straightforward migrations under 10,000 Contacts and 2,000 Deals with no custom object rebuild requirements complete in two to four weeks. Migrations involving Retainer records, large Time Entry histories, or custom ticket objects extend to six to ten weeks because of the custom object schema design, API pagination for large datasets, and the data validation phase. The Twenty documentation similarly cites two to four weeks for standard implementations with large migrations (50,000+ records) taking longer.
