Overview
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.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
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
Twenty CRM
Company
1:1Accelo 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
Twenty CRM
People
1:1Accelo 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)
Twenty CRM
Opportunity
1:1Accelo 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
Twenty CRM
Custom Object (Project)
lossyAccelo 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
Twenty CRM
Task
1:1Accelo 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
Twenty CRM
Custom Object (Support Ticket)
lossyAccelo 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
Twenty CRM
Custom Object (Time Entry)
lossyAccelo 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)
Twenty CRM
WorkspaceMember / User
1:1Accelo 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
Twenty CRM
People or Opportunity
lossyAccelo 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
Twenty CRM
Custom Object (Invoice Record) or excluded
lossyAccelo 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
Twenty CRM
Custom Object (Contract)
lossyAccelo 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
Twenty CRM
Attachments via File API
1:1Attachments 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.

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.
Accelo gotchas
Accelo REST API lacks a bulk export endpoint for large datasets
Custom field support is limited to Companies and Contacts
Accelo Payments fee structure is not migrated to destination billing
Accelo does not expose a Wikipedia article
Glitchy UI can corrupt display state during migration scoping
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 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.
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.
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.
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.
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.
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.
