Overview

What this migration involves

Moving from Onsite CRM to Monday.com CRM is a migration from a Weebly-hosted, no-API small-team CRM into a board-based work OS with CRM capabilities. Onsite CRM stores all data in a Weebly environment with no documented REST endpoint, no SDK, and no webhook infrastructure, so extraction relies entirely on in-app CSV exports. Monday.com CRM represents contacts, companies, and deals as Items on customizable boards, with custom columns replacing Onsite's custom field model and Status columns replacing pipeline stages. We request customer-supplied screenshots during scoping to confirm what the UI actually exposes, build Monday.com boards with column configurations that mirror your source data, and import through the GraphQL API. Any automations, sequences, calling, or SMS configuration in Onsite CRM do not migrate; we deliver a written board and automation inventory for your admin to rebuild.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Onsite CRM logo

Onsite CRM

What's pushing teams away

  • Extremely limited market presence with minimal third-party reviews and community discussion, making it difficult to assess long-term viability.
  • No publicly documented API, SDK, or webhook infrastructure limits integration options and blocks automated data extraction.
  • Appears to have weaker reporting and analytics depth compared to established CRM competitors like HubSpot or Pipedrive.
  • Very small user base on review platforms like G2 and Capterra suggests limited adoption and support ecosystem.
  • Lacks enterprise-grade features needed as teams scale, driving migration to platforms with better customization and API access.

Choosing

monday CRM logo

monday CRM

What's pulling them in

  • Users praise the board-based visual interface for making pipeline stages immediately legible to non-technical team members without CRM training.
  • The no-code automation builder lets sales ops teams create lead routing, stage updates, and email triggers without developer involvement.
  • Integration ecosystem connects to Slack, Gmail, Outlook, and Zapier with minimal configuration, reducing friction for teams already using these tools.
  • The flexible column system lets teams build custom CRM views — deal value, close date, lead source — without needing a developer or pre-defined schema.
  • Teams already using monday Work Management can layer CRM features onto existing boards rather than starting from scratch.

Object mapping

How Onsite CRM objects map to monday CRM

Each row shows how a Onsite 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.

Onsite CRM

Contact

maps to

monday CRM

Item (Contacts Board)

1:1
Fully supported

Onsite CRM Contact records export as CSV rows with name, email, phone, company association, and any custom field values. We map these directly to Monday.com CRM Contacts board Items. Monday.com's native contact fields (name, email, phone) accept the standard fields; any Onsite CRM custom fields map to Monday.com custom columns of the closest type (text, number, date, dropdown, or checkbox). Company association maps to the Contacts board's account link column if configured, or is preserved as a text company name column and reconciled against the Accounts board Items after import.

Onsite CRM

Company

maps to

monday CRM

Item (Accounts Board)

1:1
Fully supported

Onsite CRM Company records map to Monday.com CRM Accounts board Items. The company name becomes the Item name, and standard fields (domain, address, industry) map to corresponding Monday.com custom columns. We preserve the company-contact relationship by resolving the Monday.com Account Item ID and linking it back to each Contact Item after both boards are populated. If Onsite CRM exports company records without a unique ID column, we generate a stable hash from the company name and domain for deduplication during Monday.com import.

Onsite CRM

Deal

maps to

monday CRM

Item (Opportunities Board)

1:1
Fully supported

Onsite CRM Deal records map to Monday.com CRM Opportunities board Items. Deal name becomes the Item name, deal value maps to a Number column, close date maps to a Date column, and the pipeline stage name maps to a Status column. We extract the pipeline stage name from Onsite CRM's export and create corresponding Status column values in Monday.com's Opportunities board before importing the Deals. Owner assignment maps to Monday.com's Person column if the team member exists in the Monday.com workspace.

Onsite CRM

Pipeline Stages

maps to

monday CRM

Status Column (Opportunities Board)

lossy
Mapping required

Onsite CRM pipeline stages are extracted from the CSV export header or from screenshots provided during scoping. Each stage name becomes a Status column value in Monday.com's Opportunities board. Stage order and any probability percentages (if exported) are preserved in a separate Number column as reference values for reporting. The customer chooses whether to use Monday.com's default color scheme for stage values or to match the Onsite CRM color coding if visible in screenshots.

Onsite CRM

Activity (Call, Email, Meeting, Note)

maps to

monday CRM

Item Updates or Subitems (Opportunities Board)

1:many
Fully supported

Onsite CRM activity records (call logs, email threads, meeting records, and notes) require disaggregation because Monday.com does not have native engagement objects. We load activity history as Subitems on the relevant Opportunity Item, or as Updates on the Contact Item depending on the customer's preferred visibility model. Each activity record becomes a Subitem with type, date, duration, and notes fields. If Onsite CRM exports activities without a parent deal reference, we attach them to the Contact Item instead. Activity history volume is the primary driver of migration timeline for data-heavy accounts.

Onsite CRM

Tag

maps to

monday CRM

Tag or Label Column

lossy
Fully supported

Onsite CRM tags applied to contacts and deals migrate as Monday.com Tags attached to Items. Alternatively, if the customer prefers a structured column for reporting, tags migrate to a Labels or Multi-Select column on the relevant board. We confirm the preferred strategy during scoping based on how the customer uses tags in Onsite CRM. Tag taxonomy normalization happens at this stage: duplicates, misspellings, and case variations are cleaned before import.

Onsite CRM

User (Owner)

maps to

monday CRM

Team Member (Workspace)

1:1
Fully supported

Onsite CRM user records map to Monday.com workspace members. We extract user email addresses and names from the owner field on exported records and map them to Monday.com team member accounts by email match. Any owner without a Monday.com user account is flagged for the customer to provision before production migration. Owner assignments on Deals and Contacts map to Monday.com's Person column, which assigns the Item to the team member in the workspace.

Onsite CRM

Custom Field

maps to

monday CRM

Custom Column

lossy
Fully supported

Onsite CRM custom fields on Contacts, Companies, and Deals require manual identification during scoping. We request screenshots of the field configuration in Onsite CRM and map each to a corresponding Monday.com custom column type: text fields become Text columns, picklist values become Dropdown or Labels columns, dates become Date columns, and numeric values become Number columns. Any unsupported field type (such as a complex conditional field or a formula-based calculation) is flagged for manual review and documented as requiring post-migration configuration in Monday.com.

Pair-specific challenges

  • No API means all extraction is CSV-only from the Onsite CRM UI

    Onsite CRM has no public REST API, no SDK, and no documented webhook system according to apitracker.io. Every record that migrates must be exported from the Weebly-hosted application UI as a CSV file. If your account has more than 5,000 contacts, 2,000 deals, or complex multi-object relationships, the UI export may truncate results or produce files that require multiple sequential exports with offset ranges. We coordinate the export process with you during discovery, request screenshots of the UI to confirm what fields are actually exposed for export, and flag any object that the UI cannot fully export before we design the migration sequence.

  • Monday.com CRM uses GraphQL, not REST, for all API operations

    Monday.com CRM's API is entirely GraphQL-based, meaning all data writes go through GraphQL mutations rather than REST endpoints. Each board corresponds to a data entity (Contacts, Accounts, Opportunities), Items are the individual records, and column values are set via the change_column_value mutation. We handle the GraphQL integration directly, but this means migration scripts must construct properly typed mutation payloads with column IDs resolved before each write. Unlike REST-based CRMs where you POST to an endpoint, Monday.com imports require a column-ID-to-value mapping per board that we validate during the sandbox migration step.

  • Activity history may not export fully from the Onsite CRM UI

    CRM migration projects consistently surface that activity records (call notes, email logs, meeting history) are the most voluminous and the most likely to be incomplete in a CSV export. Onsite CRM's in-app export options may not include rich activity history in a single downloadable file, especially if the platform structures activity records differently from standard contact and deal records. We advise requesting a pre-migration export of activity records separately during scoping and budgeting time for manual activity re-entry if the export is incomplete. We document every activity that we cannot export so the customer's admin can prioritize manual re-entry for the highest-value historical records.

  • Monday.com automations require manual rebuild after migration

    Monday.com's Automation Center uses recipe-based triggers and actions scoped to individual boards. These automations are not exposed via API and cannot be extracted programmatically. Any workflow logic in Onsite CRM, including stage-change alerts, assignment rules, or notification triggers, does not migrate. We deliver a written inventory of every board structure, column configuration, and Status value mapping that we create in Monday.com during migration. Your admin rebuilds automations in Monday.com's Automation Center using the documented board configuration as the reference. We do not provide post-migration automation rebuild as standard scope.

  • Built-in calling and SMS from Onsite CRM do not transfer to Monday.com

    Onsite CRM includes built-in calling and SMS as core platform features for small teams. Monday.com CRM does not include native telephony. If your team relies on call logging and SMS threads as part of the CRM workflow, those records may exist in Onsite CRM's activity export, but the ability to make and log calls directly within Monday.com requires a third-party telephony integration such as Aircall, RingCentral, or a Zapier-connected SMS tool. We flag the telephony gap in the migration inventory so you can plan the integration setup alongside the data migration.

Migration approach

Six steps for a successful Onsite CRM to monday CRM data migration

  1. Discovery and export coordination

    We begin with a scoping call where we request screenshots of the Onsite CRM UI showing the contact list, company list, deal board or pipeline view, and any custom field configuration screens. These screenshots confirm what objects and fields the UI actually exposes for export before we design the migration sequence. We then guide you through extracting CSV files for each object: contacts, companies, deals, pipeline stages, and activities. We document the export order and any Weebly-hosted UI limitations that affect record counts or field completeness. This step typically takes three to five business days and depends on your responsiveness in providing exports.

  2. Data audit and mapping design

    We audit the exported CSV files for completeness, duplicate density, missing fields, and field-type consistency. We identify every custom field in Onsite CRM from the screenshots, map each to a Monday.com column type, and confirm the mapping with you in a written field map. We design the Monday.com board architecture: Contacts board, Accounts board, and Opportunities board with Status columns matching your pipeline stages and custom columns matching your source custom fields. We define whether activity history attaches as Subitems on Opportunities or Updates on Contacts based on your preferred visibility model. This step produces a written migration specification that both parties sign off on before any data moves.

  3. Sandbox migration and reconciliation

    We run an initial migration into a test environment using the exported CSV data. We validate row counts in Monday.com against the source CSVs, spot-check random records for field-level accuracy, and confirm that the board structure renders as expected in the Monday.com UI. Any mapping corrections, column type adjustments, or missing field additions happen in this sandbox step. We also validate that owner assignments resolve correctly and that the Status column values match the pipeline stages from the source. Customer sign-off on the sandbox results gates the production migration start date.

  4. GraphQL import and dependency sequencing

    We import records into Monday.com in dependency order: Accounts first (because Contacts link to them), then Contacts (with account links resolved), then Opportunities (with contact and account links resolved), then Tags (attached to Items), then activity Subitems or Updates (attached to the correct parent Items). Each import phase runs against the Monday.com GraphQL API with batch chunking to stay within rate limits. We log every mutation response and flag any Item that fails to create so it can be retried or reconciled. Activity history is the last phase because it requires the parent Contact and Opportunity Item IDs to be already resolved.

  5. Production cutover and automation inventory

    We coordinate a cutover window with you during which no new records are created in Onsite CRM. We run a final delta migration for any records modified after the sandbox export, verify final row counts in Monday.com, and confirm the board views are populated correctly. We then deliver the board architecture document, the column mapping reference, and the automation inventory listing every board and Status column that requires automation rebuild in Monday.com's Automation Center. We do not rebuild automations inside the migration scope. We offer a one-week hypercare window to resolve any data discrepancies surfaced in the first days of live use.

Strengths

  • Board-based UI makes pipeline stages and deal progress visually obvious without training.
  • No-code automation builder requires no developer resources to create lead routing and stage-triggered actions.
  • Flexible column system supports custom CRM fields without schema changes or admin involvement.
  • Integrates natively with Slack, Gmail, Outlook, and Zapier with minimal configuration overhead.
  • Layered product means teams already on monday Work Management can add CRM without migrating existing data.

Weaknesses

  • No native Contacts object separate from Items — contacts are managed inside a CRM module's People feature.
  • Pipeline and deal relationships use a flat item model rather than a relational object model, making complex CRM associations awkward.
  • Automations are plan-gated (250 actions/month on Standard, 25,000 on Pro) and the legacy Recipe system is being deprecated.
  • Customization and advanced views (Chart, Formula, Dependency) are locked behind Pro and Enterprise tiers.
  • Per-seat pricing with non-refundable annual billing creates cost lock-in risk during migration.

Most migrations land between two and three weeks for accounts with clean CSV exports under 10,000 contacts and 2,000 deals. Migrations with complex custom field configurations, incomplete activity history requiring manual re-entry, or large multi-board pipeline structures requiring extended scoping move to four to six weeks. The primary timeline driver is export completeness from the Onsite CRM UI rather than the Monday.com import side, since Monday.com's GraphQL API handles imports efficiently once the data is available in CSV format.
