Overview

What this migration involves

Moving from Black Ice CRM to Twenty CRM is a structural migration that starts with data extraction rather than API access. Black Ice CRM has no publicly documented API or bulk export endpoint, so we work through the application's built-in export utility or a database-level export if accessible. Black Ice's fully customisable modules mean the field set varies between deployments — we run a pre-migration field audit before building the mapping spreadsheet. We migrate Accounts to Companies, Contacts to People (with company associations), Quotes and Orders to Opportunities, Products to Standard Objects, and Potentials to Opportunities. Twenty's metadata API lets us pre-create any custom fields needed for Black Ice's deployment-specific properties. Workflows, sequences, and automation rules are not migrated; we deliver a written inventory for the customer's admin to rebuild. Stock and inventory data migrates as current-quantity and reorder-threshold fields on the Product record rather than as live inventory management.

Why teams make this switch

Two sides of the same decision

Leaving

Black Ice CRM logo

Black Ice CRM

What's pushing teams away

  • Minimal online presence and thin documentation make it difficult for teams to evaluate fit, get support answers, or find third-party integrations independently.
  • The platform appears to serve a narrow UK market with limited community resources, leaving users without the peer-driven knowledge bases available for larger CRM platforms.
  • Per-feature pricing can become costly as teams add modules, and the lack of transparent tier descriptions makes it hard to predict total cost of ownership at scale.
  • Limited known API surface and third-party integration ecosystem means teams requiring deep third-party connections may find the platform constraining.
  • Small user base means fewer pre-built migration guides, template configurations, and third-party consultants available compared to mainstream CRMs.

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 Black Ice CRM objects map to Twenty CRM

Each row shows how a Black Ice 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.

Black Ice CRM

Accounts

maps to

Twenty CRM

Company

1:1
Fully supported

Black Ice Accounts (companies) map directly to Twenty Company records. We extract company name, address fields, phone, website, and any custom fields from the Accounts module. Company is the first object imported because it is the 'one' side of the one-to-many relationship with People (Contacts). The deduplication key during import is the company name or domain if present.

Black Ice CRM

Contacts

maps to

Twenty CRM

Person

1:1
Fully supported

Black Ice Contact records map to Twenty Person objects. We preserve the contact-to-account relationship by resolving the Black Ice company association to a Twenty Company ID at import time. Fields including name, email, phone, job title, and any custom contact properties migrate directly. If Black Ice stores contacts without a company link, those Person records import without a Company association and the customer's admin can link them post-migration.

Black Ice CRM

Quotes

maps to

Twenty CRM

Opportunity

1:1
Mapping required

Black Ice Quotes map to Twenty Opportunity records. Quote header fields (quote number, date, status, total value) become Opportunity fields. Quote line items are related to the Opportunity via the opportunityId relationship in Twenty. We map the Black Ice quote status (Draft, Sent, Accepted, Declined) to a Twenty Opportunity custom field rather than assuming a direct stage mapping, as quote lifecycle differs from pipeline opportunity lifecycle.

Black Ice CRM

Orders

maps to

Twenty CRM

Opportunity

1:1
Mapping required

Black Ice Orders, which are derived from accepted Quotes, map to Twenty Opportunity records with a distinct status or a separate custom field (order_status__c) indicating they originated as orders rather than pipeline opportunities. Line items from the Black Ice Order migrate as OpportunityLineItem equivalents in Twenty. We preserve the Black Ice order-to-invoice relationship by noting the linked invoice identifier on the Opportunity record.

Black Ice CRM

Invoices

maps to

Twenty CRM

Opportunity (custom field carry-forward)

lossy
Mapping required

Black Ice Invoices are linked to Orders and carry payment status, invoice number, and line items. Twenty CRM does not have a native invoice object. We migrate invoice data as a structured custom field set on the related Opportunity (or as a separate custom Invoice object created via Twenty's metadata API if the customer requires it). Payment status and invoice number become custom fields; line items are noted in a text summary field. The customer's admin configures any downstream accounting integration (Stripe, QuickBooks, Xero) post-migration.

Black Ice CRM

Products

maps to

Twenty CRM

Standard Object

1:1
Mapping required

Black Ice Product records (name, SKU, price, stock level) map to Twenty Standard Objects with fields for name, sku, price, and stock_quantity__c as a custom field. Product associations to Orders migrate as child records linked via the Opportunity lookup. SKU maps from Black Ice's product code field.

Black Ice CRM

Stock / Inventory

maps to

Twenty CRM

Standard Object (stock_quantity__c custom field)

lossy
Mapping required

Black Ice stock levels and reorder thresholds migrate as custom fields on the Product Standard Object (stock_quantity__c and reorder_threshold__c). Twenty CRM has no native inventory management module, so live stock quantities and automated alerts do not replicate — the customer's admin sets up a post-migration inventory process or external tool. Picking list documents are application-generated derived data and do not migrate as primary records.

Black Ice CRM

Potentials / Pipeline

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Black Ice Potential records track pipeline stage and deal value. They map to Twenty Opportunity records with stage name and amount fields. We extract the Black Ice pipeline stage name and map it to a corresponding Twenty pipeline stage or a custom pipeline field if the source stage names are non-standard. Estimated value migrates as the Opportunity amount.

Black Ice CRM

Leads

maps to

Twenty CRM

Person (unmatched to Company)

1:1
Mapping required

Black Ice Leads (the primary entry point in the sales cycle) map to Twenty Person records that do not have a linked Company. We flag these at migration time as unqualified or pre-qualification records. If the customer uses a separate Leads module distinct from Contacts in Black Ice, we maintain the distinction by adding a custom field lead_source_module__c on the Person record. The customer's admin in Twenty reviews and links to a Company or converts to a Pipeline Opportunity as appropriate.

Black Ice CRM

Custom Fields (all modules)

maps to

Twenty CRM

Custom Fields via metadata API

lossy
Fully supported

Black Ice CRM's fully customisable modules mean custom fields vary by deployment. During the pre-migration field audit, we document every active custom property across Accounts, Contacts, Quotes, Orders, Products, and Potentials. We then use Twenty's /metadata API to pre-create each custom field before data import begins, matching field types (text, number, date, picklist) from the Black Ice sample export. Custom fields on Black Ice's custom modules migrate as custom fields on the corresponding Twenty Standard Object or as fields on a custom object created via metadata API.

Pair-specific challenges

  • No documented Black Ice API requires export-utility access

    Black Ice CRM does not appear in major API documentation directories and has no publicly available OpenAPI specification or rate-limit documentation. We cannot authenticate via API to pull data directly. Migration proceeds through Black Ice's built-in export utility (CSV or Excel output) or a database-level export if the customer has database access. We confirm the available export method during the discovery call before committing to a migration timeline. If the export utility has field-count limits or does not include custom fields, we negotiate a database backup or direct SQL export as the fallback.

  • Black Ice schema varies by deployment

    Black Ice CRM's fully customisable modules mean the standard field set is not consistent between installations. A customer's Quotes module may include custom fields not present in another Black Ice deployment. We require a pre-migration field audit — via a sample export or screen walkthrough — to document the actual schema before building the field mapping spreadsheet. We cannot produce an accurate migration scope or quote without this step.

  • Twenty has no native invoice or inventory management

    Black Ice CRM's full sales-cycle modules include Invoices and Stock Management. Twenty CRM does not have native invoice or inventory objects. Invoice data migrates as custom fields on Opportunity or as a custom Invoice object created via the metadata API, but payment processing, invoice PDF generation, and stock alerts do not carry forward. We flag this gap during scoping so the customer plans for a separate accounting or inventory tool post-migration.

  • Custom entity import between Twenty instances has minor support

    Twenty's own documentation acknowledges that importing custom entities into another instance has limited support and no clear method to maintain all relationships between custom objects during cross-instance transfer (GitHub discussion #7326). This affects us when the customer has Black Ice custom module data that maps to Twenty custom objects — we must validate relationship integrity post-import and may need to re-link related records manually in Twenty's UI after bulk import.

Migration approach

Six steps for a successful Black Ice CRM to Twenty CRM data migration

  1. Discovery and export method confirmation

    We audit the active Black Ice CRM modules (Leads, Accounts, Contacts, Quotes, Orders, Invoices, Products, Stock, Potentials) and confirm the available export method — built-in export utility, direct database export, or CSV download per module. We request a sample export file from each active module and use it to document the actual field schema. We identify all custom fields, their data types, and any picklist or multi-select values that need to be recreated in Twenty.

  2. Schema audit and Twenty custom field creation

    We compare the Black Ice field audit against Twenty's standard objects (Person, Company, Opportunity, Task, Note, Standard Objects). We identify standard field mappings and flag all Black Ice custom properties. We then use Twenty's /metadata API to pre-create every required custom field before any data import begins, setting correct field types (text, number, date, picklist, currency) and adding any custom objects required for Black Ice's deployment-specific modules. The customer validates the Twenty schema in a staging environment before production migration.

  3. Dependency order planning

    We plan the import sequence following Twenty's relationship dependency rules: Companies first (the 'one' side), then People (linked to Companies), then Opportunities (referencing People and Companies), then child records (line items, notes, tasks) last because they reference parent objects. Custom objects import after standard objects when they have cross-references. This sequencing prevents foreign-key violations during bulk load.

  4. Staging migration and reconciliation

    We run a full migration into Twenty staging using production-like data volume. The customer reviews record counts, spot-checks 20-30 records against the Black Ice source, and validates that custom fields populated correctly. Any mapping corrections — wrong field assignments, missing picklist values, incorrect date formats — are documented and applied before the production migration begins. This step also confirms that Black Ice stock quantities and reorder thresholds carried forward as expected on Product records.

  5. Production migration in dependency order

    We run production migration in the confirmed sequence: Companies, People (with CompanyId resolved), Opportunities (with PersonId and CompanyId resolved), Product Standard Objects, then child records including order line items, quote line items, and notes. We use Twenty's REST API with rate-limit handling and exponential backoff. Each phase emits a row-count reconciliation report before the next phase begins. Any unmapped Black Ice modules or custom fields not covered in the original scope are flagged for a supplemental import pass.

  6. Cutover, validation, and automation handoff

    We freeze Black Ice writes during the cutover window, run a final delta migration of any records modified during the migration window, then confirm Twenty as the system of record. We deliver a written inventory of Black Ice automation and workflow logic for the customer's admin to rebuild in Twenty. We support a three-day hypercare window for reconciliation issues. We do not rebuild Black Ice workflows or sequences as part of the migration scope.

Source

Strengths

  • Full sales-cycle coverage from Leads through Quotes, Orders, Invoices, and Products/Stock in a single platform.
  • Built-in inventory and product management with automatic stock reduction on order creation.
  • Per-feature pricing at $28/feature/month lets small teams start lean without paying for unused modules.
  • Fully customisable modules let teams adapt the CRM to existing workflows rather than reshape processes.
  • Configurable potential/pipeline tracking covers deal value and stage progression alongside fulfillment data.

Weaknesses

  • No publicly documented API, developer portal, or OpenAPI specification was found.
  • Per-feature pricing accumulates unpredictably as teams enable additional modules.
  • Minimal public documentation and thin online presence makes independent evaluation and support discovery difficult.
  • Customisable-per-deployment schema means no reliable standard field set across customer accounts.
  • No published free tier or free trial available to test before commitment.

Destination

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.

Most migrations land between two and three weeks for accounts with up to 10,000 records across Accounts, Contacts, Quotes, and Orders and fewer than 30 custom fields. Migrations with multiple active Black Ice modules (Invoices, Products, Stock, Potentials), more than 30 custom fields, or complex quote/order line item structures move to three to five weeks because of the field audit work, custom field creation via Twenty's metadata API, and stock-threshold transformation. The pre-migration field audit adds up to five business days to the timeline before data movement begins.
