Overview
Moving from Flash Lead Sales to Microsoft Microsoft Dynamics 365 Sales is a migration from a lead-centric SMB tool with no public API to an enterprise CRM with full REST and Bulk API access. Flash Lead Sales exports data through CSV only and stores stage progression as activity log entries rather than structured fields, requiring us to reconstruct deal timelines manually before loading into Dynamics. We map Flash Lead's Lead object to the Dynamics Lead entity, Contacts to Contact with Account linkage, and the custom pipeline stages to Dynamics Sales Process stage values. Social message threads migrate as Note attachments to the Contact record in their flattened export form. Workflows, automations, sequences, and reporting dashboards do not migrate as code; we deliver written inventories for the customer's admin to rebuild in Dynamics.
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 Flash Lead Sales object lands in Microsoft Dynamics 365 Sales , including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Flash Lead Sales
Lead
Microsoft Dynamics 365 Sales
Lead
1:1Flash Lead Sales Lead records map to Microsoft Microsoft Dynamics 365 Sales Lead entity. The primary name, email, phone, source attribution, owner assignment, and current stage migrate directly. We extract all available Lead fields from the CSV export and map them to typed Dynamics fields (string, email, phone, picklist). Any Flash Lead custom properties on the Lead record map to new custom fields (text, picklist, or multi-select depending on the source value type) that we provision in the destination Dynamics org before import. The Lead_Status in Dynamics is set to a default value during migration; the customer's admin sets the appropriate status values per their sales process.
Flash Lead Sales
Lead Stage History
Microsoft Dynamics 365 Sales
Lead (custom stage history fields)
lossyFlash Lead Sales records stage transitions as activity log entries, not as discrete stage-history fields. Only the current stage appears as a guaranteed discrete field in the CSV export. We request the full activity log export during discovery, parse stage-transition timestamps and stage names from the activity records, and reconstruct stage history as a series of custom datetime and picklist fields on the Dynamics Lead record (e.g., stage_1_name__c, stage_1_entered__c, stage_2_name__c, stage_2_entered__c). This preserves deal velocity and time-in-stage metrics that the customer uses for pipeline reporting.
Flash Lead Sales
Pipeline Stage
Microsoft Dynamics 365 Sales
Sales Process + Opportunity Stage
lossyFlash Lead Sales pipeline stages are user-defined with no enforced schema. We extract the full stage list from the customer's Flash Lead account during discovery and produce an explicit mapping table: each source stage name maps to a Dynamics Sales Process stage value (or creates a new one). Stage probability percentages map to StageProbability on the Opportunity entity once Leads are converted. Stage-specific rules or automation triggers in Flash Lead Sales cannot be migrated and are documented for rebuild in Dynamics Sales Process configuration.
Flash Lead Sales
Contact
Microsoft Dynamics 365 Sales
Contact
1:1Flash Lead Sales Contact records map to Microsoft Dynamics 365 Sales Contact. We map the primary name, email, phone, address, and any purchase history fields directly to typed Dynamics Contact fields. Contact records in Flash Lead Sales carry a relationship to the Lead record; we preserve this linkage by matching on email address during import and setting the parent Customer field or linking via a custom lookup field. Flash Lead Contact notes and conversation history migrate as Note records attached to the Contact.
Flash Lead Sales
Team Member
Microsoft Dynamics 365 Sales
User
1:1Flash Lead Sales Team Members map to Microsoft Microsoft Dynamics 365 Sales User records. We extract each Team Member's name, email, and role assignment. Owner assignment on Flash Lead Leads and Contacts is preserved in Dynamics by matching on email address against the destination User table. If a matching Dynamics User does not exist, we place the record in a reconciliation queue for the customer's admin to provision the User before record import continues. Role-based visibility in Flash Lead Sales maps to Dynamics Team or Territory sharing model configuration, which the admin configures post-migration.
Flash Lead Sales
Tag
Microsoft Dynamics 365 Sales
Multi-Select Picklist or Custom Text Field
lossyFlash Lead Sales tags are applied to Leads without limit and serve as a segmentation mechanism. We export all tags as a comma-separated list per Lead and map them to a Dynamics multi-select picklist field (if tag count is under 150 distinct values) or a custom text field (if tag count exceeds Dynamics picklist limits). The customer chooses tag strategy during scoping. Tags used for lead categorization migrate as-is; tag-based filtering logic in Flash Lead Sales does not migrate and must be rebuilt as Dynamics Views or filters.
Flash Lead Sales
Lead Source
Microsoft Dynamics 365 Sales
Custom Field on Lead
1:1Flash Lead Sales Lead Sources (Facebook, Instagram, Referral, Purchased List, etc.) are preserved as a custom field on the Dynamics Lead record. We extract the source label from the Lead record and populate a custom picklist or text field (lead_source_label__c) in Dynamics. If the customer uses Dynamics 365 Marketing, the source label maps to the lead's originating campaign or channel for attribution.
Flash Lead Sales
Invoice
Microsoft Dynamics 365 Sales
Invoice
1:1Flash Lead Pro invoices migrate to Microsoft Dynamics 365 Sales Invoice records. We extract invoice amount, status (Draft, Sent, Paid, Void), related Contact or Lead reference, line items, and date fields. Invoice PDF attachments migrate as ContentDocument linked to the Invoice record. Custom invoice fields and formatting templates do not transfer and are documented for rebuild in Dynamics Invoice templates.
Flash Lead Sales
Social Message Thread
Microsoft Dynamics 365 Sales
Note (on Contact)
1:1Flash Lead Sales Facebook Messenger and Instagram DM threads export as flat conversation text logs attached to the Contact record. Thread branching, message timestamps (individual), and read receipts are not preserved in the export format. We attach the full conversation log as a Note record linked to the corresponding Dynamics Contact, noting the limitation in the migration report so the customer can assess whether conversation history is business-critical for support or compliance purposes.

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.
Flash Lead Sales gotchas
No documented public API for programmatic export
Lead stage history stored as activity log rather than discrete fields
Custom pipeline stages require explicit mapping per account
Social message threads export as flat text without thread structure
Microsoft Dynamics 365 Sales gotchas
Professional tier 15-table custom table limit blocks migrations
October 2024 pricing increase applies at renewal for all customers

Migration approach
Discovery and export verification
We audit the Flash Lead Sales account to identify all available export objects (Leads, Contacts, Pipeline Stages, Team Members, Tags, Invoices, Social Messages), confirm which objects the customer has populated, and request CSV exports of all objects. We verify that tags, stage history, and source attribution are included in the download before scoping finalizes. If the customer has invoicing enabled, we request invoice exports with line item detail. We also capture the complete list of custom stage names, probability percentages, and pipeline configuration from the Flash Lead dashboard to build the stage mapping table.
Stage history reconstruction from activity log
We request the full activity log export from Flash Lead Sales to capture stage transition events. We parse the activity log to extract each Lead's stage history (stage name, entry timestamp, exit timestamp) and reconstruct it as custom fields on the Dynamics Lead record. This step runs before the main record import and produces a stage-history transform that we apply during the Lead load into Dynamics.
Microsoft Dynamics 365 Sales schema design
We design the destination schema in Microsoft Dynamics 365 Sales . This includes provisioning custom fields on Lead and Contact (stage history fields, lead source, original stage from Flash Lead), configuring the Sales Process with stage values mapped from the Flash Lead stage list, setting up Record Types if the customer has multiple pipelines, and creating User records or mapping to existing Active Directory-synced Users for owner assignment. Schema is deployed into a Dynamics Sandbox (Full Copy or Partial Copy) first for validation.
Sandbox migration and reconciliation
We run a full migration into the Dynamics Sandbox using production-like data volume. The customer's RevOps lead or Dynamics admin reconciles record counts (Leads in, Contacts in, stage history preserved, activity log attached), spot-checks 25-50 random records against the Flash Lead source export, and signs off the schema and mapping before production migration begins. Stage mapping corrections, field type adjustments, and tag strategy decisions happen in Sandbox, not production.
User provisioning and owner reconciliation
We extract every distinct Team Member and owner referenced on Flash Lead Leads and Contacts and match by email against the Microsoft Dynamics 365 Sales destination org's User table. If the customer uses Microsoft Entra ID (formerly Azure Active Directory) for identity, we coordinate with their IT admin to confirm that User provisioning will sync. Owners without a matching Dynamics User go to a reconciliation queue. Migration cannot proceed to the record load phase until all OwnerId references have a valid destination User or are flagged for admin action.
Production migration in dependency order
We run production migration in record-dependency order: Users (manual provisioning validated), Accounts (if Contacts reference them), Contacts (with owner resolved), Leads (with stage history reconstructed and stage mapping applied), Tags and Lead Sources (custom field population), Invoices (with related Contact resolved), Social Message threads (as Note attachments to Contact). Each phase emits a row-count reconciliation report before the next phase begins. We use the Dynamics Bulk API or Data Import Wizard for CSV loading with chunking for large record sets.
Cutover, validation, and automation rebuild handoff
We freeze Flash Lead Sales write access during cutover, run a final delta migration of any records modified during the migration window, then enable Microsoft Dynamics 365 Sales as the system of record. We deliver a written inventory of all Flash Lead Sales automations, workflow rules, and sequence settings with recommended Dynamics equivalents (Dynamics Sales Process, Power Automate, or Sales Engagement) for the customer's admin to rebuild post-migration. We support a one-week hypercare window where we resolve any reconciliation issues. We do not rebuild Flash Lead automations as Dynamics workflows inside the migration scope.
