Overview
Moving from Fortifi to Twenty CRM is a migration from an all-in-one billing-centric platform to an open-source relationship-focused CRM. Fortifi orbits its data model around Customers, Actions, Conversions, and Invoices under usage-based tier limits; Twenty CRM uses the standard Company-Contact-Opportunity model with a /metadata API for custom objects and a CSV import path for bulk records. The primary migration risk is Fortifi's lack of published API documentation, which forces us to assess CSV export and manual extraction capabilities during discovery. We sequence the migration with parent records (Users, Companies) first, then Contacts, then Opportunities and Subscriptions, then Activity history as Tasks, and finally any custom properties via Twenty's metadata API. Workflows, dunning sequences, and renewal automations in Fortifi do not migrate; we deliver a written inventory for your admin to rebuild in Twenty. The open-source nature of Twenty means there is no per-contact or per-seat vendor lock-in after migration, and the data belongs to you on your own infrastructure.

Object mapping
Each row shows how a Fortifi 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.
Fortifi
Customer
Twenty CRM
Company + Contact
1:manyFortifi Customers split into Twenty's Company record (company-level fields: name, domain, address) and a primary Contact record (personal fields: name, email, phone, job title). The split is based on whether the Fortifi Customer record contains person-level or organization-level data. We preserve the original Customer ID in a custom field for cross-reference during reconciliation.
Fortifi
Subscription
Twenty CRM
Custom Object (Subscription)
1:1Fortifi Subscription records define recurring billing models, plan assignments, and cycle data. These map to a Twenty custom object created via the /metadata API before migration. Fields include plan name, billing cycle, start date, status, and a lookup to the parent Company. Advanced billing rules (proration, trial extensions) are flagged for manual review post-migration.
Fortifi
Invoice
Twenty CRM
Custom Object (Invoice)
1:1Fortifi Invoice records carry full financial data: line items, payment status, due dates, tax codes, and totals. We migrate these to a Twenty custom Invoice object with a lookup to the parent Company and Subscription. Invoice PDFs are stored as attachments linked via ContentDocumentLink. Payment history is preserved as a related custom object or as fields on the Invoice record.
Fortifi
Action
Twenty CRM
Task
1:1Fortifi Actions are behavioral event logs against Customers (page views, form submissions, feature usage). We map these to Twenty Task records with type classification preserved in the Subject or a custom field, and a link to the parent Company or Contact via WhatId or the primary relationship field.
Fortifi
Conversion
Twenty CRM
Opportunity
1:1Fortifi Conversions represent marketing or sales goal completions tied to workflows. We map Conversion records to Twenty Opportunity, preserving attribution data (source, campaign, channel) in Opportunity fields and a link to the primary Company. If Fortifi tracks a monetary value on the Conversion, that becomes the Opportunity Amount.
Fortifi
Twenty CRM
Task + Comment
1:1Fortifi Email records include sent, delivered, opened, and bounced states with template associations. We migrate the email body and metadata as a Twenty Task (activity timeline entry) linked to the parent Company or Contact. Template associations and engagement states are preserved in custom Task fields for reporting.
Fortifi
Interaction
Twenty CRM
Task
1:1Fortifi Interactions track customer touchpoints across support and engagement channels. We map Interaction records to Twenty Task with channel type (phone, chat, email, in-person) preserved in the Subject or a custom field, timestamp preserved as ActivityDate, and body or notes migrated as the Task description.
Fortifi
User
Twenty CRM
WorkspaceMember (Twenty)
1:1Fortifi User records include role and permission assignments. We extract active Users by email match against Twenty WorkspaceMembers. Role names migrate as custom fields on the WorkspaceMember record. Permission set details are documented for manual verification post-migration.
Fortifi
Custom Properties
Twenty CRM
Custom Fields (via /metadata API)
lossyFortifi supports custom fields on Customers and potentially other objects. We discover the custom property schema during scoping, pre-create equivalent custom fields in Twenty via the /metadata API before data migration, and map values field-by-field. Any Fortifi custom property without a clear Twenty equivalent is flagged with a data type recommendation.
Fortifi
Automation Workflows
Twenty CRM
Not migrated (inventory only)
1:1Fortifi automation rules, dunning sequences, and renewal triggers are configuration-level settings stored in the platform and not exportable as data records. We document the full automation configuration during discovery including trigger conditions, action sequences, and timing rules, and deliver this as a written handoff document for the customer's admin to rebuild in Twenty. This is not in standard migration scope.

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.
Fortifi gotchas
Usage-based pricing tiers impose hard migration boundaries
No publicly documented API endpoint reference
Initial setup complexity for B2B operations
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 export capability assessment
We audit the source Fortifi account for tier level (Essential/Team/Startup), record volumes across Customers, Actions, Conversions, Emails, Interactions, Invoices, and Subscriptions, custom property schemas, user count, and pipeline configurations. Because Fortifi has no documented public API, we specifically assess whether CSV/UI export is available for each object and whether direct database access is an option. The discovery output is a written migration scope with record counts, extraction method per object, and a tier-fit analysis for the customer's chosen Twenty plan.
Schema design in Twenty and custom object provisioning
We design the destination schema in Twenty. This includes creating custom objects for Invoice and Subscription via the /metadata API, adding any custom fields to Company and Contact that map from Fortifi custom properties, and configuring the Opportunity stage values to reflect the Fortifi pipeline and Conversion data. If the customer runs Twenty on self-hosted infrastructure, we recommend deploying the migration into the managed cloud instance first or using a dedicated staging environment to avoid the version-update blank-CRM risk documented in GitHub issue #14705.
Data extraction and staging
We extract data from Fortifi using the available method (CSV export or manual pull) and stage it in a secure migration workspace. Because Fortifi lacks a programmatic API, extraction may require multiple batch exports. We deduplicate records, standardize date formats, resolve email-to-Company associations, and apply any data quality rules before transformation. This phase emits a record-count manifest per object for customer sign-off before any data loads into Twenty.
Owner and user reconciliation
We extract every distinct Fortifi User referenced on Customer, Subscription, Invoice, and Interaction records and match by email against Twenty WorkspaceMembers. Any Fortifi User without a matching Twenty WorkspaceMember goes to a reconciliation queue. The customer's admin provisions missing WorkspaceMembers before migration resumes. Owner assignment on migrated records cannot proceed until this step is complete.
Production migration in dependency order
We run production migration into Twenty in dependency order: WorkspaceMembers (manual provisioning validated), Companies (from Fortifi Customers), primary Contacts (linked to Companies), Opportunities (from Fortifi Conversions with Amount and attribution), Tasks (from Actions, Interactions, Emails), Custom objects (Subscriptions and Invoices via pre-created schema), and finally any custom field data. Each phase emits a row-count reconciliation report. Activity records are linked to parent Companies and Contacts with ActivityDate preserved from the Fortifi timestamp.
Cutover, validation, and automation inventory handoff
We freeze Fortifi as the system of record, run a final delta migration of any records modified during the cutover window, then enable Twenty as the live CRM. We deliver the automation configuration inventory documenting every Fortifi dunning sequence, renewal trigger, and workflow rule with trigger conditions, action sequences, and recommended Twenty equivalents for manual rebuild. We support a one-week post-migration window for reconciliation issues. Workflow rebuilds and post-migration admin training are not in standard scope and are handled as separate engagements.
