Overview
Moving from OnePageCRM to Monday.com CRM is a structural redesign, not a direct record copy. OnePageCRM uses a flat data model where contacts are the primary record and Next Action logic drives the sales workflow. Monday.com CRM uses a board-based architecture where every record type is an item on a customizable board with columns, groups, and views. We translate OnePageCRM Contacts into Monday CRM People items, Organizations into linked People items or a separate Organizations board, and Deals into a Deals board with pipeline stage columns. We preserve the Next Action date as a custom date column. The key limitation is that OnePageCRM cannot export email body content or attachments through its native CSV or API endpoints, so we flag this gap during scoping and carry over available metadata (addresses, dates, subject lines) while documenting exactly which records have missing email content. Autoflow workflow templates and Predefined Actions do not migrate; we deliver a written recipe inventory for the customer's admin to rebuild in Monday's Automation Recipes.

Object mapping
Each row shows how a OnePageCRM 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.
OnePageCRM
Contact (Person)
monday CRM
People Item (CRM board)
1:1OnePageCRM Contact records map to Monday CRM People items on the CRM People board. We map standard fields (name, email, phone, address, social URLs) to their corresponding Monday column types. Custom contact fields map to Monday columns of equivalent type (text, number, date, dropdown). Next Action date from OnePageCRM maps to a custom date column NA_next_action_date__c. We deduplicate by email address on import and flag any contacts with duplicate emails for manual reconciliation.
OnePageCRM
Organization (Company)
monday CRM
People Item (linked) or Organizations board
1:manyOnePageCRM Organization records map to Monday.com People items with a company_name column filled in, or optionally to a dedicated Organizations board if the customer uses Monday's multi-entity linking. We preserve the contact-to-organization linkage by storing the organization reference as a text column or linking items via Monday's relation column. Company-level custom fields map to Monday columns with equivalent types.
OnePageCRM
Deal
monday CRM
Item on Deals board
1:1OnePageCRM Deals map to Monday CRM deal items on the Deals board. Deal name, amount, pipeline stage, close date, margin, commission, and cost map to corresponding Monday columns. The deal's associated Contact maps to a Person or link column pointing to the CRM People board item. We configure the Deals board's Group By setting to mirror OnePageCRM's pipeline stages using Monday's Status column.
OnePageCRM
Deal Stage / Status
monday CRM
Status column on Deals board
lossyOnePageCRM Status values (Prospect, Qualified, Customer, etc.) map to Monday Status column options on the Deals board. We create a Status column with options that match the source taxonomy, preserving the ordering for Kanban view grouping. Closed-Won and Closed-Lost statuses from OnePageCRM carry over as terminal Status options with color coding.
OnePageCRM
Custom Fields (Contacts, Organizations, Deals)
monday CRM
Columns on respective boards
1:1OnePageCRM custom fields must be pre-created in the destination board as columns before migration. We provide a custom field checklist during scoping so that all source custom fields have a Monday column equivalent created in advance. Unsupported column types (e.g., OnePageCRM multi-select tags exceeding Monday's dropdown length) are flagged and mapped to text columns with pipe-delimited values as a fallback.
OnePageCRM
Tags
monday CRM
Tags column or Labels column
1:1OnePageCRM tags assigned to Contacts carry through as Monday Tags or Labels column values. Tags are stored as a flat namespace and imported as-is. If the customer uses tags for segmentation, we recommend using Monday's Tags column for filtering and reporting. Tags do not merge or de-duplicate across records; we carry the full source tag set.
OnePageCRM
Lead Source
monday CRM
Dropdown or Labels column
1:1OnePageCRM Lead Source values (website inquiry, phone call, referral, etc.) map to a Monday Dropdown column on the CRM People board. Pre-populated values migrate as dropdown options; we create any missing options before import so that the Lead Source maps cleanly without manual post-import correction.
OnePageCRM
Notes and Call Logs
monday CRM
Updates or Subitems on People/Deal items
1:1OnePageCRM notes and call logs attached to Contacts migrate as Updates on the corresponding People item or as Subitems on the related Deal item. Call duration and disposition data migrate as text columns on the Subitem. Email body content is not available from OnePageCRM's export; we carry available metadata (addresses, dates) and document which records have missing content.
OnePageCRM
Predefined Items (Product Catalog)
monday CRM
Items on Products board or Price column
1:1OnePageCRM Predefined Items representing products or services map to a Monday Products board or to the Price column on Deals items. We preserve item name, price, quantity, and grouping. Grouping maps to Monday Group labels or a Tags column. Products used in multiple Deals need a separate Products board with relation columns pointing to Deals items.
OnePageCRM
Owner
monday CRM
Person column or assignee column
1:1OnePageCRM owners assigned to Contacts, Organizations, and Deals map to Monday Person columns. We resolve owners by email match. Any owner without a matching Monday user account goes to a reconciliation queue; the customer provisions the missing user before record import resumes. Owner assignment on Deals migrates as an Assignee column with the matched user.

Pair-specific challenges
Migration approach
Discovery and board design
We audit the source OnePageCRM portal for contact count, organization count, deal count, pipeline stages, custom fields per object, active tags, lead sources, and deal velocity metrics. We pair this with a Monday.com CRM board-design session: we create the empty CRM People board, Deals board, and optional Organizations board with all column types defined (status, date, person, text, number, labels). We deliver a written board specification and field mapping worksheet before any data extraction begins.
Data extraction and deduplication
We extract OnePageCRM data via CSV export endpoints for bulk records and API v3 for targeted lookups (custom field metadata, relationship verification). We run pre-import deduplication on email address as the primary key, flagging duplicates for the customer's admin to resolve. We also extract and normalize organization-contact linkages so that the Monday.com relation column or linking strategy is satisfied at import time. Custom fields are verified against the board specification to ensure every source field has a destination column.
Board building and column configuration in Monday.com
We build the destination boards in Monday.com CRM using the board specification. Status columns are populated with the source pipeline stage values. Person columns are configured for user assignment. Tags and Lead Source columns are set up with the source taxonomy as options. Next Action dates are mapped to a custom date column. If the customer has an existing Monday.com Work Management workspace, we integrate the CRM boards into the workspace structure without overwriting existing boards.
Staging migration and reconciliation
We run a full migration into a staging Monday.com account using production-like data volume. The customer's admin reconciles record counts (People items in, Deals items in, Organizations in), spot-checks 20-30 random records against the OnePageCRM source, and verifies that custom field values, statuses, and owner assignments transferred correctly. Any mapping corrections (wrong column type, missing status option, incorrect relationship) happen in staging before production.
Production migration in dependency order
We run production migration in record-dependency order: CRM People board (Contacts and Organizations first, with organization linkage resolved), Deals board (with contact reference resolved via Monday's relation column or linked item), Tags and Lead Source normalization, and Notes/Call Logs as Updates or Subitems. Each phase emits a row-count reconciliation report. We freeze OnePageCRM writes during the final cutover window and run a delta migration for any records modified during migration.
Cutover, validation, and Autoflow inventory handoff
We enable Monday.com CRM as the system of record after the delta migration completes. We deliver a written Autoflow inventory document listing every active OnePageCRM workflow with its trigger, conditions, actions, and recommended Monday.com Automation Recipe equivalent. We do not rebuild Autoflow workflows inside the migration scope; that work is handled by the customer's admin using Monday's automation builder. We support a 72-hour hypercare window for reconciliation issues raised by the sales team during initial live use.
