Overview
Moving from Tango CRM to Monday.com CRM is a migration from a platform with no confirmed public API to one that uses a REST API with board-and-item architecture rather than a traditional object model. Without a documented API on the source side, we begin every engagement with export-path discovery: CSV exports where available, browser-assisted record capture otherwise. We map Tango CRM Contacts to Monday People entities, Companies to Item-name fields on Account boards, and Deals to Item rows on pipeline boards with pipeline stages mapped to Monday Groups. Custom fields on Contacts and Deals resolve to Monday column types (text, number, date, dropdown, checkbox). Activity history (calls, emails, meetings, tasks) transfers as Item updates and Activity Log entries. Monday.com automations, formula columns, and dashboard widgets do not migrate as code; we deliver a written inventory for the customer's admin to rebuild post-migration.
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 Tango CRM object lands in monday CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Tango CRM
Contact
monday CRM
People entity (Board Column: Person type)
1:1Tango CRM Contact records map to Monday.com People entities and to Person-type column values on the CRM board. Standard fields (name, email, phone, address) map to Name, Email, Phone, and Location column types. Email addresses serve as the dedupe key during import. Custom Contact properties (dropdown, date, number, text) map to equivalent Monday column types. Multi-select tag fields from Tango CRM split into individual Monday label or checkbox column values.
Tango CRM
Company
monday CRM
Item on Account Board (Item name + columns)
1:1Tango CRM Company records map to Item rows on a Monday.com Account board with the Company Name as Item name. Industry, size, website, and address fields map to text, number, or dropdown columns on the board. We set up the Account board before Contact migration so that Contact Items can link to their parent Company via a Link-to-Items column.
Tango CRM
Deal
monday CRM
Item on Pipeline Board (Group = Stage)
1:1Tango CRM Deal records map to Item rows on Monday.com Pipeline boards. Each pipeline stage in Tango CRM becomes a Monday Group (left-side column divider) on the destination board. Deal value, expected close date, and owner map to numeric, date, and person column types respectively. Stage labels do not map 1:1; we produce a stage mapping worksheet during scoping and apply the reconciliation at import time.
Tango CRM
Pipeline
monday CRM
Board with Groups
lossyTango CRM pipeline definitions (stage order, stage labels, stage automation hooks) export as board configuration. We recreate each pipeline as a separate Monday.com Board with Groups representing stages. Group order and names are applied from the mapping worksheet. Monday.com does not have native stage-level probabilities; probability tracking requires a separate numeric column if needed.
Tango CRM
Activity: Email
monday CRM
Item Update or Activity Log
1:1Tango CRM logged emails map to Monday.com Item Updates with email body text and timestamp preserved. Without a first-class engagement object in Monday.com, emails appear as chronological updates on the Item's update stream, tagged with a label for type identification. The source Contact or Deal Item is linked via the Item's existing relationships.
Tango CRM
Activity: Call
monday CRM
Item Update or Activity Log
1:1Tango CRM logged calls map to Monday.com Item Updates with call duration, disposition, and notes in the update body. We include a type label (Call In, Call Out, Missed) in the update text for filtering. Call recording links, if available from the source, migrate as text URLs in a Link column on the Item.
Tango CRM
Activity: Meeting
monday CRM
Item Update or Calendar Integration
1:1Tango CRM meeting engagements map to Monday.com Item Updates with meeting title, attendees, location, and outcome text. If the customer uses Google Calendar or Outlook integration with Monday.com, meetings may also appear as calendar events; we document the calendar sync configuration separately during handoff.
Tango CRM
Activity: Task
monday CRM
Item Update or Sub-item
1:1Tango CRM logged tasks (completed activities) map to Item Updates with task description, status, and completion timestamp. Open tasks in Tango CRM can optionally map to Monday.com sub-items on the parent Contact or Deal Item if the customer prefers task-level tracking in the board; this is confirmed during scoping.
Tango CRM
Note
monday CRM
Item Update
1:1Free-text notes from Tango CRM migrate as Item Updates on the linked Contact or Deal Item. HTML-formatted notes are stripped to plain text. If the note references an attachment, we note the reference in the update text and document it in the post-migration checklist for manual re-upload since Monday.com does not store file attachments natively within notes.
Tango CRM
Owner/User
monday CRM
Monday.com Workspace Member
1:1Tango CRM Owners map to Monday.com workspace members by email address. We extract the owner list from the source export and match against the destination workspace's member roster. Any Tango CRM owner without a matching Monday.com account is held in a reconciliation queue for the customer's admin to provision before record import begins. Role and permission sets do not transfer.
Tango CRM
Custom Field
monday CRM
Board Column (by type)
lossyTango CRM custom properties on Contacts, Companies, and Deals map to Monday.com board column types: text fields to Text columns, numbers to Numbers, dates to Date, dropdowns to Dropdown or Tags, checkboxes to Checkbox, and URLs to Link. We produce a column mapping worksheet during the mapping phase. Dropdown fields require value-level mapping if the destination uses a picklist that must be pre-populated.
Tango CRM
Attachment
monday CRM
None (documented for manual re-upload)
1:1File attachments stored within Tango CRM records (uploaded documents, signed contracts, images) cannot be extracted without a confirmed API endpoint or download mechanism. We do not migrate attachments to avoid silent data loss. We document every attachment reference found during scoping in a post-migration checklist that the customer's admin uses to manually re-upload files to the destination Item or linked storage.

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.
Tango CRM gotchas
No public API confirmed limits automation options
Attachment extraction is unconfirmed
Pipeline stage names rarely align between CRMs
monday CRM gotchas
Subitems are not included in bulk exports
Daily API call limits vary sharply by plan
Legacy automations (Sentence Builder) are being deprecated
Excel and account exports only include table views
Enterprise admins can disable non-admin exports
Pair-specific challenges
Migration approach
Export-path discovery and scoping
We begin every Tango CRM engagement by confirming the available data export mechanism. We attempt CSV export for Contacts, Companies, Deals, and Activities directly within the Tango CRM interface. If CSV exports are incomplete (missing custom fields, no activity history), we assess browser-assisted record capture using a structured extraction tool. The discovery call covers record volume by object, presence of custom fields, activity history depth, pipeline count, and attachment references. The output is a written migration scope with a confirmed or provisional export path and an honest assessment of what requires manual preparation on the source side.
Monday.com board design and column mapping
We design the destination Monday.com workspace structure: an Account board for Companies, CRM boards for Contacts with Person columns, and Pipeline boards for Deals with Group-based stages. We produce a column mapping worksheet that maps each Tango CRM field (standard and custom) to a typed Monday.com column. Dropdown fields on the destination are pre-populated with values from the source. We configure Link-to-Items columns to connect Contact Items to their parent Account Item. The board design is validated in a staging workspace before any production data is written.
Export extraction and staging
We extract data from Tango CRM using the confirmed export path: CSV downloads where available, or structured browser capture. Exports are staged in our migration environment with record counts validated against the source system. We flag and clean duplicate records (Contacts with duplicate emails, Companies with matching domain names) before transformation. Any unmapped custom fields are itemized and escalated to the customer for manual field mapping or decision to exclude.
Transformation and pipeline stage reconciliation
We transform staged data into Monday.com-ready format: Company names become Item names, Contact fields map to Person and text columns, Deal fields map to numeric and date columns, and pipeline stages map to Group names based on the mapping worksheet. Stage probability values, if present, populate a custom numeric column on the Pipeline board. Activity records (calls, emails, meetings, tasks) transform into Item Updates with type labels and timestamps. Owner emails resolve to Monday.com workspace member IDs.
Production migration in dependency order
We run production migration in board order: Account board first (Company Items), then Contact boards (with Account link resolved), then Pipeline boards (Deal Items with Group stage assignment and Account link). Activity history and Notes import as Item Updates after the parent Items are confirmed in place. Owner reconciliation runs concurrently: any owner without a Monday.com account is escalated before the relevant Items are imported. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation handoff
We freeze writes to Tango CRM during cutover, run a final delta migration of any records modified during the migration window, then mark the Monday.com boards as the system of record. We deliver the automation, formula, and dashboard inventory document to the customer's admin. We support a three-day hypercare window for reconciliation issues raised by the sales team. Monday.com automations, workflows, and dashboards require manual rebuild by the admin and are not included in standard scope.
