Overview
Migrating from Zendesk Sell to Monday.com CRM is a time-bound project: Zendesk's sunset date of August 31, 2027 means every record left in Sell after that date is deleted per Zendesk's Service Data Deletion Policy. Monday.com CRM presents itself as a flexible, board-based sales tool with AI agents, native Campaigns for email marketing, and over 200 automation recipes, priced from $12 per user per month. We extract Leads, Contacts, Companies, Deals, Tasks, Notes, and custom field values from Sell's API, map them into Monday.com's Items, Boards, and Column schema, and load via Monday.com's REST API. We do not migrate Sell Sequences as cadence state, Sell Workflows as automation code, or Sell call recordings as audio files; these require separate rebuild or file-transfer steps. The pair-specific gotchas center on Sell's API rate limits during export, Monday.com's column-type constraints on custom field values, and the structural difference between Sell's Pipeline-plus-Stage container and Monday.com's flat Board view.
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 Zendesk Sell 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.
Zendesk Sell
Lead
monday CRM
Contact (or Lead item type)
1:1Sell Leads are early-stage prospects that can convert to Contacts and Deals. Monday.com CRM represents people as Contacts by default, though teams can configure a separate Board with a Lead item type if they want a pre-qualification stage. We migrate Sell Lead fields (name, email, phone, source, status, owner, and any custom Lead Fields) as Contact Items in the primary CRM Board. If the customer requires Lead-to-Contact conversion semantics, we document the board structure change and configure a Status column with pre-conversion and post-conversion stages during Monday.com setup.
Zendesk Sell
Contact
monday CRM
Contact
1:1Sell Contacts map directly to Monday.com Contacts. Standard fields (first name, last name, email address, phone number, primary company) migrate as typed Contact fields. Custom Contact Fields from Sell migrate as Monday.com Column types: text fields to Text columns, numeric values to Number columns, dates to Date columns, and picklist-style values to Dropdown or Tags columns depending on multi-select semantics.
Zendesk Sell
Company
monday CRM
Company
1:1Sell Companies map to Monday.com Companies, which serve as the organization-level record in Monday.com CRM. Company name, domain, address, industry, and any custom Company Fields migrate as Company properties. Contact-to-Company associations in Sell become Contact records linked to the same Company in Monday.com. Monday.com's Contact-Company relationship model supports multiple Contacts per Company, which aligns with Sell's one-to-many Contact-on-Company model.
Zendesk Sell
Deal
monday CRM
Deal (Item on CRM Board)
1:1Sell Deals migrate as Items on a Monday.com CRM Board. The Deal name, value (amount), expected close date, owner, associated Contact and Company links, loss reason, and deal source migrate as Item properties and Column values. We resolve Sell's parent Contact and Company references at migration time and populate Monday.com's built-in Contact and Company links on each Deal Item. Custom Deal Fields map using the same column-type resolution logic used for Contacts and Companies.
Zendesk Sell
Pipeline
monday CRM
Board
lossySell Pipelines are top-level workflow containers. Each Sell Pipeline maps to a separate Monday.com CRM Board. Teams with multiple Sell Pipelines (Professional tier supports unlimited) receive one Monday.com Board per Pipeline to preserve pipeline-level segmentation. We document the Pipeline name and default currency as Board-level metadata during migration.
Zendesk Sell
Stage
monday CRM
Status Column options
lossySell Stages are children of Pipelines, ordered by ordinal position with win/loss flags per stage. We map each Stage to a Status column option in Monday.com, preserving the stage name and ordinal position. Closed-Won and Closed-Loss stages in Sell map to the corresponding final-state status values in Monday.com. Stage probability percentages migrate as informational notes that the customer's admin can apply to Monday.com's Forecasting feature if available on their tier.
Zendesk Sell
Task
monday CRM
Task (Subitem on Deal Item)
1:1Sell Tasks with due dates, assignees, completion status, and descriptions migrate as Subitems on the related Deal Item in Monday.com CRM. Task due date maps to the Subitem Due Date column, assignee to the Person column, and completion status to the Subitem Status column. If a Task has no parent Deal, it migrates as a Subitem on the related Contact or Company Item. Notes attached to Tasks migrate as Subitem comments in Monday.com.
Zendesk Sell
Note
monday CRM
Comment on Contact, Company, or Deal Item
1:1Sell Notes are free-text records attached to Contacts, Deals, Leads, or Companies. We migrate Note body as a Comment on the equivalent Monday.com Item (Contact, Company, or Deal). Note creation timestamp and the note author (owner) migrate as comment metadata and attribution. If the note has attachments, we migrate the attachment URL as a Link column value and flag the file transfer for a separate step if the attachment is not a hosted URL reference.
Zendesk Sell
Tag
monday CRM
Tags Column
1:1Sell Tags applied to Contacts, Deals, and Leads migrate as Monday.com Tags column values on the equivalent Item. Monday.com's Tags column supports multiple labels per Item, matching Sell's multi-tag model. We note that Monday.com's tag-based filtering operates at the board or group level, which may differ from Sell's tag-query behavior in list views.
Zendesk Sell
User (Owner)
monday CRM
User
1:1Sell Users (sales reps and admins) export with email, name, role, and territory. We match Sell users to Monday.com workspace members by email address. Any Sell Owner without a matching Monday.com user goes into a reconciliation queue for the customer's admin to provision the account before record import. Territory assignments in Sell are noted as a separate configuration step in Monday.com because Monday.com's territory management is accessed through the admin workspace settings.

Pair-specific challenges
Migration approach
Discovery and data audit
We audit the source Zendesk Sell account to produce a complete record count: Leads, Contacts, Companies, Deals, Tasks, Notes, Tags, custom field definitions, and user count. We also document Sell Pipeline names, Stage names, and the stage probability matrix. Given the August 31, 2027 sunset, we schedule the discovery call with a migration-start target that gives at least nine months before the deadline to avoid last-minute constraints on specialist availability. The discovery output is a written scope document with record counts, a Sell-to-Monday.com object mapping draft, and a board-structure proposal for the Monday.com destination.
Monday.com workspace and board structure setup
We work with the customer's Monday.com admin to provision the workspace, create CRM Boards (one per Sell Pipeline), configure Status columns to match Sell stage names and order, and define Column types for all standard and custom fields. This step is completed in the customer's live Monday.com workspace before any data load begins. Any board structure changes after migration begins require a reconciliation pass that adds cost and timeline, so we lock the schema at this stage based on the approved mapping document.
Data export from Zendesk Sell with rate-limit handling
We export data from Zendesk Sell via the Sell Core API, reading Leads, Contacts, Companies, Deals, Tasks, Notes, and Tags in dependency order. The Sell API permits 36,000 requests per hour per token; we implement rate-limit-aware polling with exponential backoff on 429 responses and throttle batch submissions to stay below the job queue limit of 30 concurrent background jobs. Custom field IDs are resolved to field keys during export using the custom fields mapping endpoint. The export produces a staging dataset with a record-count reconciliation report for the customer's review before transformation begins.
Data transformation and column-type mapping
We transform the Sell export dataset into Monday.com API format: Sell Leads become Contact Items, Sell Contacts become Contact Items, Sell Companies become Company Items, Sell Deals become Deal Items on the appropriate Board, and Tasks become Subitems on parent Deal Items. Custom field values are mapped to Monday.com Column types based on the column-type resolution decisions from scoping. Tags are mapped to Tags column values. Notes are converted to Item comments. Owner email addresses are resolved against the Monday.com user list to produce valid Person column values. The transformation layer emits a data quality report flagging any records with missing required fields, invalid email formats, or broken parent references for the customer's review before import.
Monday.com import and parent-record resolution
We import data into Monday.com via the Monday.com REST API using batch inserts. The import order respects dependency constraints: Companies first (so Contact links resolve), then Contacts, then Deals with their Contact and Company links, then Tasks as Subitems, then Notes as comments. Owner resolution ensures that each imported Item has a valid Person column value for the assigned owner. We apply the same rate-limit-aware polling used in the export phase, reading Monday.com API rate-limit headers and pausing between batches to avoid throttling. Each import phase emits a row-count reconciliation report against the transformation output.
Cutover, validation, and automation rebuild handoff
We freeze writes to Zendesk Sell during the cutover window, run a final delta migration of any records modified during the migration window, and mark Monday.com as the system of record. We deliver a validation report comparing record counts in Sell against Monday.com, with spot-check reconciliation of 25-50 records per object type against the source. We deliver the Sequences metadata reference document, the Sell Workflow inventory (as a written handoff document for the customer to use when rebuilding automations in Monday.com's automation builder), and a board-structure summary for the customer's admin to configure Monday.com's Campaigns, AI agents, and Forecasting features. We support a one-week post-go-live window for reconciliation issues raised by the sales team.
