Overview

What this migration involves

Moving from ChartMogul to Twenty CRM is a migration from a billing-centric analytics platform with a lightweight CRM layer to an open-source CRM that prioritizes flexibility and data ownership. ChartMogul enforces a two-level customer model (parent Customer records owning tags, opportunities, and custom attributes, with child Data Source Customer records holding invoices and transactions per connected billing source) that must be decomposed and re-composed during migration scoping. We extract the parent and child objects separately from ChartMogul's API, resolve the external_id linkage before importing into Twenty, and preserve MRR and ARR as custom number fields on the Company record since Twenty has no native subscription metric engine. Activity history (calls, emails, meetings, tasks) migrates as Tasks and Notes linked to the correct Person and Company. Workflows, sequences, MRR movement exports, forecast projections, and cohort tables do not migrate; we deliver a written inventory of every automation and metric for the customer's admin to rebuild or re-derive post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

ChartMogul logo

ChartMogul

What's pushing teams away

  • The CRM module is lightweight compared to dedicated sales platforms—contacts lack deep activity timelines and deal management is basic, causing teams to outgrow it.
  • Multi-currency handling requires manual configuration and does not auto-detect currency switches mid-customer lifecycle, creating reporting drift for global businesses.
  • ChartMogul's export capabilities are limited to CSV and Google Sheets; teams needing real-time warehouse feeds find the BigQuery/S3 integration too batch-oriented for operational use.
  • Historical data older than your connection date is unavailable unless explicitly imported, and retroactive imports require re-running metric calculations that hit plan limits.

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 ChartMogul objects map to Twenty CRM

Each row shows how a ChartMogul 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.

ChartMogul

Customer (parent record)

maps to

Twenty CRM

Company

1:1
Fully supported

The parent Customer record (with tags, custom attributes, notes, call logs, opportunities, and tasks) maps to a Twenty Company. The ChartMogul customer name becomes the Company name field. We use ChartMogul's customer UUID as the Company record's external_id so that child Data Source Customer records can reference it correctly. Tags migrate as text tags on the Company; custom attributes migrate as custom fields on the Company object after the customer configures the field schema in Twenty's Data Model settings.

ChartMogul

Data Source Customer (child record)

maps to

Twenty CRM

Company (secondary record)

1:many
Fully supported

Each child Data Source Customer created by a connected billing source (Stripe, Chargebee, Recurly) maps to a secondary Company record tagged as a billing source instance, linked to the parent Company via a custom Company relationship field. This preserves the ChartMogul two-level model as two distinct Company records with a defined relationship rather than collapsing it into one record and losing the billing source attribution.

ChartMogul

Subscription

maps to

Twenty CRM

Custom fields on Company + Product

1:many
Fully supported

ChartMogul Subscriptions (with plan_id, quantity, billing cycle, MRR contribution, status) do not have a direct Twenty CRM equivalent since Twenty has no native subscription tracking object. We map active subscriptions to custom fields on the Company record (subscription_status__c, subscription_mrr__c, subscription_plan__c) and import plan definitions as Product records in Twenty's Products module so that opportunity line items can reference them.

ChartMogul

Plan

maps to

Twenty CRM

Product

1:1
Fully supported

ChartMogul Plan definitions (name, interval, amount, currency, trial period) map to Twenty Product records. The plan's monthly recurring amount becomes the Product's price. Plan intervals (monthly, annual, quarterly) map to Product billing intervals where applicable. We import plan definitions before subscriptions so that subscription_plan__c references resolve correctly.

ChartMogul

Invoice

maps to

Twenty CRM

Task + custom fields on Company

1:1
Fully supported

ChartMogul Invoices (with line items, amounts, taxes, and transaction fees) migrate as a combination of a closed-won Opportunity record (with the invoice amount as the Opportunity amount and the invoice number as the Opportunity name) and a Note record attached to the Company holding the full invoice detail. We read ChartMogul's transaction fee handling setting during scoping and apply it consistently so that the Opportunity amount reflects the net revenue after fees.

ChartMogul

Transaction

maps to

Twenty CRM

Note or custom fields on Company

1:1
Fully supported

Payments, refunds, and chargebacks are imported as Notes attached to the parent Company, preserving the transaction type, amount, date, and currency. For accounts with high transaction volume, we consolidate transactions into monthly summary records on the Company rather than importing each individual payment as a separate Note, reducing import volume while preserving financial history.

ChartMogul

MRR Movement

maps to

Twenty CRM

Custom fields on Company

1:1
Fully supported

ChartMogul's MRR Movement records (new business, expansion, contraction, churn, reactivation) are not natively supported as objects in Twenty. We derive a current MRR figure and MRR movement history from ChartMogul's export and store the most recent MRR state as custom number fields on the Company record (current_mrr__c, mrr_last_updated__c). Historical movement breakdowns are documented in a CSV delivered alongside migration for the customer to build reporting on in Twenty's dashboarding.

ChartMogul

Opportunity

maps to

Twenty CRM

Opportunity

1:1
Fully supported

ChartMogul CRM Opportunities (with stage, amount, owner) map directly to Twenty Opportunities. The ChartMogul dealstage maps to a Twenty Opportunity stage (which the customer configures during workspace setup). Open and won opportunities migrate with stage, amount, close date, and owner preserved. Closed-lost opportunities migrate at the customer's discretion to preserve historical pipeline data.

ChartMogul

Engagement: Call

maps to

Twenty CRM

Task (subtype: call)

1:1
Fully supported

ChartMogul call logs migrate to Twenty Task records with the call disposition, duration, and notes preserved in the Task body. The Task is linked to the correct Company or Person record by resolving the customer reference at migration time. Activity timestamps are preserved so the timeline ordering is maintained.

ChartMogul

Engagement: Email

maps to

Twenty CRM

Task + Note

1:1
Fully supported

ChartMogul email engagement records migrate as a Task (representing the activity timeline entry) with a linked Note holding the email body and metadata (sender, recipient, subject). The Task is linked to the Company or Person record; the Note is attached via Twenty's file linking mechanism. Email attachments migrate as Note attachments where present in the source record.

ChartMogul

Engagement: Meeting

maps to

Twenty CRM

Task

1:1
Fully supported

ChartMogul meeting engagements (with attendees, location, start and end time) migrate as Task records with the meeting title as the Task subject and meeting notes in the Task body. Attendee information is stored as a text list in the Task since Twenty does not have a native EventAttendee object equivalent.

ChartMogul

Engagement: Note and Call Log

maps to

Twenty CRM

Note

1:1
Fully supported

ChartMogul Notes and call logs migrate as Note records attached to the parent Company record. The note creation date and author are preserved in the Note metadata. Call logs include disposition and duration in the note body as plain text since Twenty does not have a structured call log object.

Pair-specific challenges

  • Two-level customer model requires parent-child split

    ChartMogul separates customer data into a parent Customer record (owning tags, custom attributes, notes, opportunities, tasks) and child Data Source Customer records (one per connected billing source, owning invoices and transactions). Migrating directly into a single Twenty Company record orphans the billing source history. We handle this by first importing all Data Source Customers as secondary Company records tagged by billing source, then linking them to the parent Company via a custom relationship field. The customer must configure this custom Company-to-Company relationship field in Twenty's Data Model before migration begins.

  • MRR and ARR have no native home in Twenty CRM

    ChartMogul's core value proposition is its subscription metric engine calculating MRR, ARR, NRR, GRR, and cohort retention. Twenty CRM has no equivalent metric calculation layer. We preserve the most recent MRR and ARR state as custom number fields on the Company record, but the dynamic MRR movement waterfall (new business, expansion, contraction, churn) cannot be represented natively. We deliver the full MRR movement history as a CSV alongside migration so the customer's admin can build reporting in Twenty's dashboard module or a connected BI tool.

  • ChartMogul API rate limit at 40 req/s throttles bulk export

    ChartMogul's API caps at 40 requests per second with additional compute-time and parallel-connection limits. Large invoice histories and full engagement timelines can require tens of thousands of API calls, making the export phase the longest single step in the migration. We mitigate this by chunking reads with cursor-based pagination, applying 25ms inter-request delays, and running export batches during off-peak hours. The migration timeline estimate includes a buffer for rate-limit throttling on the ChartMogul source side.

  • Transaction fee handling must be aligned before invoice migration

    ChartMogul's transaction fee handling setting (controlling whether Google Play and PayPal fees are deducted from revenue) affects the net invoice amount and therefore the MRR attribution. If this setting was not configured before the historical import in ChartMogul, the revenue figures will be understated. We read the current fee handling configuration during scoping, apply it consistently to all transaction imports, and flag any discrepancy between the intended setting and what was applied historically so that the customer can decide whether to correct the source data before migration.

  • Cohort membership cannot be backdated in ChartMogul before import

    ChartMogul assigns cohort membership at import time based on the customer's first_seen_at timestamp. If the customer imports historical data with backdated timestamps in ChartMogul, the MRR movements will backdate correctly but cohort boundaries may not align with the intended monthly cohorts. We validate cohort boundary alignment during migration validation and advise the customer if the cohort MRR in the destination will differ from ChartMogul's reported historical cohort data. This is a known limitation of ChartMogul's cohort model, not a migration defect.

Migration approach

Six steps for a successful ChartMogul to Twenty CRM data migration

  1. Discovery and scoping audit

    We audit the source ChartMogul account across billing sources (number of connected Stripe, Chargebee, Recurly, PayPal, or app store integrations), parent Customer count, total Data Source Customer records, subscription volume, invoice count, transaction count, engagement history length, and active workflow/sequence count. We pair this with a Twenty workspace audit: current field schema, configured Pipelines and stages, existing custom fields, and API access tokens. The discovery output is a written migration scope document with record counts per object, a preliminary object mapping, and a recommended Twenty field schema to pre-configure before data import.

  2. Twenty workspace pre-configuration

    We guide the customer through creating the custom field schema in Twenty's Data Model before any data import begins. This includes custom number fields for MRR and ARR on the Company object, a Company-to-Company relationship field for the parent-child billing source linkage, a subscription_status__c text field, and any custom fields mapped from ChartMogul's custom attributes. We also configure the Opportunity Pipeline and stages to align with ChartMogul's deal stages. Schema configuration is validated in Twenty's sandbox or a duplicate workspace before production migration begins.

  3. ChartMogul API extraction with rate-limit throttling

    We extract data from ChartMogul's REST API using cursor-based pagination and 25ms inter-request delays to stay within the 40 req/s rate limit. The extraction runs in dependency order: Plans first (for Product creation), then parent Customers, then Data Source Customers with external_id linkage to parents, then Subscriptions, then Invoices, then Transactions, then Opportunities, then Engagements. Each extraction phase emits a row-count reconciliation against the source account before the next phase begins. Large engagement histories are chunked into weekly batches to prevent memory exhaustion and to allow mid-extraction validation.

  4. Parent-child customer linkage and Company import

    We import parent Customer records into Twenty as Company records, using ChartMogul's customer UUID as the external_id for cross-reference. We then import Data Source Customer records as secondary Company records tagged with the billing source name (e.g., stripe_customer, chargebee_customer), and create the Company-to-Company relationship records linking each child to its parent. This step establishes the two-level model in Twenty and must complete before any invoice or subscription import that references a customer.

  5. Subscription and invoice migration

    We import Plans as Product records in Twenty, then map active Subscriptions to the custom MRR and subscription fields on the parent Company. Invoices migrate as closed-won Opportunities with the invoice amount, invoice number as the Opportunity name, and a Note attached to the parent Company containing the full invoice detail. We apply the transaction fee handling setting during this phase to ensure the net amounts reflect the correct revenue after fees. Transaction histories (payments, refunds, chargebacks) are consolidated into monthly summary Notes on the parent Company to manage import volume.

  6. Engagement history and metric preservation

    Calls, emails, meetings, and notes from ChartMogul migrate as Task and Note records linked to the parent Company. The most recent MRR and ARR values are written to the custom number fields on each Company record. We deliver the full MRR movement history as a CSV file alongside migration so the customer's RevOps team can build movement reporting in Twenty's dashboard module or a connected BI tool. The CSV includes customer name, movement type (new business, expansion, contraction, churn, reactivation), MRR delta, and effective date.

  7. Cutover, final validation, and automation handoff

    We freeze writes in ChartMogul during cutover, run a final delta extraction for any records modified during the migration window, and close out the ChartMogul API session. We deliver a written inventory of every active ChartMogul Workflow and Sequence with trigger conditions, actions, and recommended equivalents in Twenty's Workflow builder. We do not rebuild automations in Twenty; that work is handled by the customer's admin using the inventory document. We support a one-week hypercare window to resolve reconciliation issues raised during the first user acceptance testing cycle in Twenty.

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.
