Overview
Moving from Manta Business Management Software to Twenty CRM is a migration from a closed, poorly-documented small-business CRM into an open-source platform that self-hosts for free. The primary technical constraint is that Manta BMS publishes no documented public API, which means data extraction depends entirely on whatever manual or built-in export the platform exposes at the time of migration. We verify export availability during scoping and escalate immediately if only partial or screen-scraped exports are possible. Twenty CRM requires all fields to exist in Settings before CSV import, so we pre-create custom fields for every non-standard Manta property before import begins. Workflows, automations, and attachments do not migrate; we deliver a written inventory of any Manta automations for the customer's admin to rebuild in Twenty.
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 Manta Business Management Software 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.
Manta Business Management Software
Contact
Twenty CRM
Person
1:1Manta BMS Contacts map to Twenty CRM Person records. Standard fields (name, email, phone, address) transfer directly. We flag any Manta custom contact properties during scoping because Twenty requires these fields to be pre-created in Settings before CSV import. Company affiliation from Manta maps to the Person's Company link in Twenty via a lookup that we resolve after Companies are imported first.
Manta Business Management Software
Company
Twenty CRM
Company
1:1Manta BMS Company records map directly to Twenty CRM Company records. Company name, domain, industry, employee count, and address fields transfer where present. If the Manta export does not include company-contact linkage, we rebuild the Person-to-Company relationship during migration by matching on domain or company name as a secondary pass after both objects are imported.
Manta Business Management Software
Lead
Twenty CRM
Person (filtered by type)
1:manyManta BMS Lead records with a distinct lifecycle status (new, contacted, qualified) map to Twenty CRM Person records tagged with a Lead type or source field. We preserve the original Manta lead status value in a custom field so the customer's admin can segment migrated leads in Twenty after import. Leads without a Manta counterpart in Contacts are imported as Persons with a source attribution to Manta.
Manta Business Management Software
Deal
Twenty CRM
Opportunity
1:1Manta BMS Deals map to Twenty CRM Opportunity records. Deal name, value, stage, and expected close date transfer directly. Pipeline stage names from Manta must be reviewed and matched to Twenty stage options during scoping; stage probability percentages are not automatically carried and require manual configuration in Twenty's pipeline settings before migration.
Manta Business Management Software
Activity (call, email, meeting, task)
Twenty CRM
Task or Note
1:1Manta BMS activity records (calls, emails, meetings, tasks) map to Twenty CRM Tasks and Notes. We extract the activity type, timestamp, subject, body, and associated contact reference from the Manta export where linkage data is available. Activities without a clear associated record in the Manta export import as standalone Notes in Twenty, flagged as orphaned. Activity records with rich HTML content are converted to plain-text Notes.
Manta Business Management Software
User / Owner
Twenty CRM
Member
1:1Manta BMS Users referenced as Deal owners, Lead assignees, or Activity creators map to Twenty CRM Members. We match by email address. Any Manta user without an email match in the export goes to a reconciliation queue for the customer's admin to provision the corresponding Twenty member before record import resumes. Archived or inactive Manta users are excluded from migration unless explicitly requested.
Manta Business Management Software
Custom Field (Contact)
Twenty CRM
Custom Field (Person)
lossyManta BMS custom fields on Contact records require pre-creation in Twenty CRM Settings before import. We inventory every custom field during scoping, verify its presence in the export, and pre-create the corresponding Twenty field with the correct data type (text, number, date, select) in the customer's Twenty workspace before the import phase begins. If a Manta custom field has no schema documentation, we flag it and exclude it from migration.
Manta Business Management Software
Custom Field (Deal)
Twenty CRM
Custom Field (Opportunity)
lossyManta BMS custom fields on Deal records map to Twenty CRM custom fields on the Opportunity object. We apply the same pre-creation workflow: inventory, verify export availability, create the field in Twenty, then import. Deal-level custom fields that reference picklist values require those options to be whitelisted in Twenty's field settings before import.
Manta Business Management Software
Custom Object
Twenty CRM
Custom Object
1:1If Manta BMS contains custom objects beyond the standard Contact, Company, Lead, Deal, and Activity set, we map them to Twenty CRM Custom Objects. Twenty's data model supports custom objects with lookup relationships to standard objects (Person, Company, Opportunity). We pre-create the custom object schema in Twenty including all custom fields and relationship fields before any data loads. Custom object naming follows Twenty's conventions and is verified with the customer during scoping.
Manta Business Management Software
Attachment / File
Twenty CRM
Not Migrated
1:1Manta BMS does not expose a documented file storage export, and Twenty CRM handles attachments as file uploads within its own interface rather than as importable records. We do not migrate attachments as binary files. If the Manta export includes file URLs or references, we note them in the migration inventory and the customer handles file re-upload manually post-migration.
Manta Business Management Software
Tag / Label
Twenty CRM
Custom Text Field or Tag
lossyManta BMS tags and labels on Contact or Deal records map to a custom text field in Twenty CRM. We recommend a comma-separated custom field for simplicity, or a multi-select field if Twenty's field type supports it at the time of migration. Tag strategy is confirmed during scoping based on the customer's segmentation needs in Twenty.
Manta Business Management Software
Lead Status
Twenty CRM
Custom Select Field (Person)
lossyManta BMS Lead status values (new, contacted, qualified, unqualified) migrate as a custom select field on the Twenty CRM Person record. We extract the status from the Manta export and map each distinct value to a corresponding Twenty select option. The customer configures which status values represent active pipeline leads versus closed leads during scoping.
Manta Business Management Software
Deal Stage
Twenty CRM
Custom Select Field (Opportunity)
lossyManta BMS pipeline stage names (appointment scheduled, proposal sent, negotiation, closed won, closed lost) map to a custom select field on the Twenty CRM Opportunity record. We inventory every distinct stage value from the Manta export and pre-create matching select options in Twenty before Deal import. Probability percentages are noted in the mapping document for the customer to configure manually in Twenty's pipeline settings post-migration.
Manta Business Management Software
Phone Number
Twenty CRM
Phone Field (Person, Company)
1:1Manta BMS phone numbers on Contact and Company records map to Twenty CRM phone fields on Person and Company. We normalize phone number formats to a standard string representation during the transform phase. Multiple phone numbers (mobile, work, home) from Manta map to a single phone field in Twenty unless the customer's migration scope includes a multi-phone custom field setup.

Manta Business Management Software gotchas
No documented public API for data export
Custom fields are not migratable
Extremely limited review and technical data
Brand confusion with manta.com directory and Manta Flow (IBM)
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
Export verification and scoping
We attempt a trial extraction from Manta BMS using whatever built-in export the platform exposes at the time of the discovery call. We verify record counts for Contacts, Companies, Leads, Deals, Activities, and Users; confirm whether custom field values appear in the export; and identify any gaps that require manual extraction or screen-scraping. If the export is incomplete or unavailable, we escalate immediately and adjust the migration scope to include only reliably extractable data. The scoping output is a written data inventory and a confirmed migration object list.
Twenty workspace preparation
We create all required fields in the customer's Twenty workspace before any import begins. This includes standard fields that Twenty omits by default (industry, employee count, website, jobTitle, department) and every custom field identified in the Manta export. For Opportunity records, we pre-create the pipeline stage select options to match Manta's stage names. For Person records, we pre-create the lead status select options. The customer reviews and approves the field list before we proceed to import.
Member provisioning in Twenty
We extract every distinct Manta BMS user referenced as an owner, assignee, or activity creator and match by email against the Twenty workspace Members list. Any Manta user without a matching Twenty member goes to a reconciliation queue. The customer provisions the missing Twenty members before record import begins. We cannot import Opportunity or Person owner assignments without a resolved Member record, so this step gates the import phase.
Company and Person import in dependency order
We import records in dependency order: Companies first (no dependencies), then Persons with company affiliation resolved via the Company lookup, then Opportunities with Person and Member lookups resolved. Each phase emits a row-count reconciliation report before the next phase begins. Any record rejected due to a missing required field or a broken lookup reference is captured in an error log for the customer to resolve before we re-run that phase.
Activity history and engagement migration
We import Manta BMS activity records (calls, emails, meetings, tasks) as Twenty Tasks and Notes. We link each activity to its associated Person or Company where the Manta export includes a contact reference. Activities without a contact reference are imported as standalone Notes and flagged in the reconciliation report for the customer to review. The import preserves original timestamps to maintain activity timeline ordering in Twenty.
Cutover, validation, and automations handoff
We freeze writes to Manta BMS during the cutover window, run a final delta migration of any records modified since the initial export, and confirm row-count reconciliation across all objects. We deliver a written inventory of any Manta BMS automations or workflows that require manual rebuild in Twenty. We do not rebuild automations or configure workflows inside the migration scope. We support a one-week post-cutover window for reconciliation issues raised by the customer's team.
