Overview

What this migration involves

Zinc is an HR-focused SaaS platform centered on candidate referencing, background checks, and employee onboarding workflows. Salesforce Sales Cloud is a customer relationship management platform built around accounts, contacts, opportunities, and custom objects. The two platforms share a relational object model but differ fundamentally in their primary entity: Zinc optimizes for the candidate and employment lifecycle; Salesforce optimizes for the account-revenue relationship. Migrating from Zinc to Salesforce requires translating candidate records into Contact objects, employment histories into custom objects with lookup relationships, and background-check results into custom fields or related records. FlitStack AI accesses Zinc via its REST API to extract records with full field fidelity, transforms each record to match Salesforce's schema conventions, and loads via the Bulk API to handle large record volumes without hitting API rate limits. Workflows, email templates, and automation logic built in Zinc do not transfer — we export definitions as JSON for your team to rebuild in Salesforce Flow or Apex. The result is a Salesforce org with your complete recruiting and employment history, ready for reporting from day one.

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

Zinc

What's pushing teams away

  • Lack of live chat support forces users to rely on a chatbot or email, which some find inadequate for time-sensitive hiring queries.
  • Admin visibility into usage volumes — how many checks remain or have been used — is limited in the standard UI, frustrating finance and HR operations teams.
  • Custom check builder lacks an accessible backend view for some administrators, making it hard to audit or manage check usage at scale.

Choosing

Salesforce Sales Cloud

What's pulling them in

  • The AppExchange marketplace with 5,000+ prebuilt apps gives enterprises integrations for nearly every business workflow without custom development.
  • Native Einstein AI for lead scoring, opportunity insights, and predictive forecasting adds intelligence without a separate platform purchase.
  • Territory management, multi-currency support, and advanced forecasting satisfy the needs of complex B2B sales organizations with structured revenue teams.
  • Slack, Tableau, and CPQ are deeply integrated into the core platform, keeping the sales stack unified for teams already in the Salesforce ecosystem.
  • Organizations with a large, established Salesforce implementation choose it because switching costs — integrations, custom code, trained admins — are prohibitive.

Object mapping

How Zinc objects map to Salesforce Sales Cloud

Each row shows how a Zinc object lands in Salesforce Sales Cloud, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Zinc

Candidate

maps to

Salesforce Sales Cloud

Contact

1:1
Fully supported

Zinc's Candidate record maps directly to Salesforce Contact. Name, email, phone, address, and LinkedIn URL translate to standard Contact fields. Original create and update timestamps are preserved as custom datetime fields since Salesforce's CreatedDate reflects the migration load date, not the original record date.

Zinc

Candidate.employment_history

maps to

Salesforce Sales Cloud

Employment_History__c (Custom Object)

1:1
Fully supported

Zinc stores employment history as an array of objects within the Candidate record. Each employment entry becomes a separate Employment_History__c record with a lookup to the Contact. Job title, company name, start/end dates, and responsibilities map to custom fields on the custom object.

Zinc

Background Check

maps to

Salesforce Sales Cloud

Background_Check__c (Custom Object)

1:1
Fully supported

Zinc's background-check results attach to the Candidate record as structured data (check type, status, completed date, verdict). Since Salesforce has no native background-check object, we create a Background_Check__c custom object with lookup to Contact and fields for each data point. If only a single check is needed per candidate, a set of custom fields on Contact suffices.

Zinc

Onboarding Checklist

maps to

Salesforce Sales Cloud

Onboarding_Milestone__c (Custom Object)

1:many
Fully supported

Zinc tracks onboarding as a step-by-step checklist (document signed, equipment provisioned, IT access granted, training completed). Each step becomes an Onboarding_Milestone__c record with a pick-list for milestone type, a status field, and a completion date. The parent Contact represents the employee being onboarded.

Zinc

Position / Job Opening

maps to

Salesforce Sales Cloud

Position__c (Custom Object) + Opportunity

many:1
Fully supported

Zinc positions (open roles being hired) can map to a custom Position__c object for reference. If the hiring process includes revenue-linked positions, Opportunity records with a custom Position__c lookup capture the recruiting pipeline as a sales-like funnel in Salesforce, with stage values for sourcing, screening, interviewing, and offer.

Zinc

Interview

maps to

Salesforce Sales Cloud

Event

1:1
Fully supported

Zinc interview records (interviewer, candidate, date/time, feedback) map to Salesforce Event records linked to the Contact. Event Type field captures the interview stage; Event Description holds the feedback summary. Interviewer email resolves to the Salesforce user record via email matching.

Zinc

Reference

maps to

Salesforce Sales Cloud

Reference__c (Custom Object)

1:1
Fully supported

Zinc's reference records (referee name, relationship, contact info, responses) migrate to a custom Reference__c object with a lookup to the Contact (candidate). Reference responses and ratings map to custom fields on the object. Salesforce does not have a native reference-tracking object.

Zinc

Reference

maps to

Salesforce Sales Cloud

Reference__c (Custom Object)

1:1
Fully supported

Zinc reference records capture referee name, relationship type, contact information, ratings, and written response notes for each candidate. Each reference migrates as a separate Reference__c custom object record linked to the Contact representing the candidate via a lookup relationship. Ratings and response text populate custom fields on the Reference__c object. Salesforce lacks a native reference-tracking entity, so the custom object is created during the schema setup phase with fields matching Zinc's data structure. If your organization uses an AppExchange reference-management application, FlitStack can map to that app's objects instead provided you supply the API names during planning.

Zinc

Attachment / Document

maps to

Salesforce Sales Cloud

ContentDocument / Salesforce Files

1:1
Fully supported

Zinc attachments (resumes, cover letters, signed documents) are downloaded and re-uploaded to Salesforce as ContentDocuments linked to the relevant Contact or custom object. File size limits of 25MB per Salesforce file apply; larger files require chunked upload or external storage with a link stored in Salesforce.

Zinc

User / Team Member

maps to

Salesforce Sales Cloud

User

1:1
Fully supported

Zinc users (recruiters, hiring managers) resolve to Salesforce users by email address. Unmatched users are flagged before migration so the team can either invite them to Salesforce or assign records to a fallback owner. Role and team membership from Zinc maps to Salesforce Role and Permission Sets.

Zinc

Workflow / Automation

maps to

Salesforce Sales Cloud

Flow

1:1
Fully supported

Zinc's reference-checking and onboarding automation sequences do not have a direct Salesforce equivalent. FlitStack AI exports the workflow definitions as JSON with step logic, triggers, and conditions. Your Salesforce admin rebuilds these in Flow using the exported definitions as a configuration reference.

Zinc

Email Template

maps to

Salesforce Sales Cloud

Email Template

1:1
Fully supported

Zinc email templates used in reference-request communications and onboarding notification sequences do not migrate automatically. FlitStack AI exports the complete template content as HTML files including styling, merge fields, and body copy. Your team recreates these as Salesforce Email Templates or Apex-based templates using the exported HTML as the starting point. Salesforce supports Visualforce email templates and Lightning email templates; the appropriate format depends on your org's configuration. This manual recreation step is scoped separately from the data migration and typically takes 1–3 days depending on the number of templates and their complexity.

Pair-specific challenges

  • Zinc's Candidate Record Has No Direct Salesforce Equivalent — Custom Schema Required

    Zinc's candidate-centric data model treats employment history, background checks, and onboarding milestones as nested objects attached to a single candidate record. Salesforce has no native equivalent to this structure — Contact records have no native way to store rich employment history or multi-step onboarding state without custom objects. FlitStack AI creates the Employment_History__c, Background_Check__c, and Onboarding_Milestone__c custom objects with the appropriate lookups before migrating any data. If your Salesforce org already has custom HR objects, we map to those instead. This schema setup step adds 1–3 days to the project timeline and requires a Salesforce admin to approve the object and field definitions before data loads begin.

  • Zinc Workflows Do Not Transfer — Reference Data Exported for Manual Rebuild

    Zinc automates reference-checking request sequences and onboarding task progressions as native workflows. Salesforce has no equivalent to these logic flows at the migration level — the automation engine (Zinc's workflow engine vs. Salesforce Flow) is entirely different. FlitStack AI exports Zinc workflow definitions as structured JSON including trigger conditions, step sequences, assignee logic, and notification rules. Your Salesforce admin uses this JSON as a configuration reference to rebuild equivalent Flows. This is a manual step that typically takes 1–4 weeks depending on the number of workflows and their complexity. Email templates used within Zinc workflows are exported as HTML files and must be re-created as Salesforce email templates.

  • Background Check Data Requires a Custom Object or Field Set — No Native Salesforce Object

    Zinc stores structured background-check results (type, status, verdict, completed date) on the candidate record. Salesforce has no standard object for background checks — the standard Contact object has no background_check_status field. We handle this by creating a Background_Check__c custom object with lookups to the Contact. If your compliance team requires check results to be visible on the Contact record directly without a related list, we instead create a set of custom fields on Contact (Background_Check_Status__c, Background_Check_Type__c, Background_Check_Completed_Date__c) and optionally link the full structured record as a related list. Your Salesforce admin chooses the display approach during schema setup.

  • Zinc API Pagination May Split Large Record Exports Across Multiple API Calls

    Zinc's REST API returns paginated results for candidate lists and employment history arrays. For organizations with 50,000+ candidate records, extraction requires handling cursor-based pagination across multiple API calls, which increases extraction time and requires careful tracking of resume cursors to avoid duplicate records in the migration set. FlitStack AI's extraction layer tracks pagination state, de-duplicates records by Zinc ID, and logs every API call for audit purposes. If Zinc's API rate limits are hit during extraction, the job backs off and retries with exponential backoff — this can extend the extraction phase by several hours for very large datasets.

  • Onboarding Milestone Sequencing Requires a Custom Object with Order Field

    Zinc's onboarding checklist preserves step order (step 1: sign offer letter, step 2: complete I-9, step 3: provision laptop, etc.). Salesforce custom objects do not have a native ordering mechanism — list views sort by field values, not by insertion order. To preserve milestone sequence, we add an Integer field (Milestone_Sequence__c) to the Onboarding_Milestone__c custom object that maps Zinc's step order. Salesforce list views and reports sort by Milestone_Sequence__c to reproduce the original checklist order. Alternatively, Salesforce Flow can re-create the ordered step logic, but that falls under the workflow-rebuild scope.

Migration approach

Six steps for a successful Zinc to Salesforce Sales Cloud data migration

  1. Audit Zinc's data model and extract record taxonomy

    FlitStack AI connects to Zinc via API using scoped read credentials and inventories all candidate records, employment history entries, background check records, onboarding milestones, interviews, references, and offers. We document every field on every object, note pick-list value sets, identify null-rate fields, and flag records with missing required data. This audit produces a migration scope document that your team reviews before we proceed — it also surfaces records that should be excluded (test records, duplicate entries, archived candidates beyond the retention window).

  2. Design and deploy Salesforce custom schema

    Before data moves, FlitStack AI delivers a schema setup plan specifying every custom object and field required: Employment_History__c, Background_Check__c, Onboarding_Milestone__c, Reference__c, and any custom fields on the Contact object (Candidate_Status__c, LinkedInUrl__c, Original_Created_Date__c, Source_System_ID__c). Your Salesforce admin (or our team with admin credentials) creates these objects and fields in the target org. We provide field-level security recommendations so the correct profiles can access sensitive fields like background check verdicts. Schema deployment is validated before any data load begins.

  3. Resolve Zinc users to Salesforce users by email

    Every Zinc owner (recruiter, hiring manager) is matched to a Salesforce User record by email address. FlitStack AI generates a pre-migration owner resolution report listing matched users, unmatched users, and suggested fallback assignments. Records assigned to unmatched owners are flagged — your team either creates Salesforce User accounts for those people before migration or designates a fallback user to own those records. No record loads into Salesforce without a valid OwnerId; this prevents orphaned records with no assigned user.

  4. Run sample migration with field-level diff across all object types

    A representative slice of records (typically 100–500 spanning candidates, employment history, background checks, and onboarding milestones) migrates first. FlitStack AI generates a field-level diff report comparing source values against destination values for every mapped field. You verify that employment dates, check statuses, milestone sequences, and owner assignments are accurate. Any mapping errors are corrected before the full run commits. The sample migration also validates that custom object relationships (lookups from Onboarding_Milestone__c to Contact, Background_Check__c to Contact) resolve correctly and that Salesforce validation rules do not reject any records.

  5. Execute full migration with delta-pickup and post-load reconciliation

    The full migration runs in waves organized by object dependency: Contact records first (parent), then Employment_History__c and Background_Check__c (children), then Onboarding_Milestone__c and Reference__c (grandchildren). Salesforce Bulk API handles the high-volume loads. A delta-pickup window of 24–48 hours captures any records created or modified in Zinc during the cutover window so Salesforce reflects the final state at go-live. FlitStack AI reconciles loaded record counts against source record counts and flags any discrepancy. An audit log records every operation, and one-click rollback reverts the org to its pre-migration state if reconciliation uncovers critical issues.

Source

Strengths

  • Structured digital reference reports replace unstructured phone calls, producing consistent, comparable data across hires.
  • Fast turnaround from request to completed reference — multiple reviews cite 48-hour or next-day completion timelines.
  • Integration ecosystem connects to major ATS and HRIS platforms, automating request dispatch and result ingestion.
  • Configurable check templates let companies tailor questions to role level and department without rebuilding from scratch.
  • High customer satisfaction — 4.7/5 on G2 with 83% five-star ratings across 174 reviews.

Weaknesses

  • No live chat or real-time support channel — users are directed to a chatbot or email for assistance.
  • Admin and finance users have limited self-service visibility into check consumption, volume usage, and remaining quota.
  • Integration settings and webhook configurations must be manually re-established after any migration, with no automated export of these settings.
  • Custom check templates with non-standard scoring rubrics may not map cleanly to alternative reference-checking platforms.

Strengths

  • Largest enterprise app ecosystem in CRM with 5,000+ AppExchange integrations covering nearly every vertical workflow.
  • Native Einstein AI delivers lead scoring, opportunity insights, and predictive forecasting without a third-party layer.
  • Advanced territory management, multi-currency, and flexible forecasting satisfy complex B2B revenue structures.
  • Deep platform extensibility: Custom Objects, Apex, Flow, and the Metadata API allow full schema customization.
  • Well-documented REST API, Bulk API, and Composite API with published rate limits for programmatic migration.

Weaknesses

  • Pricing model is layered and opaque in practice: per-seat fees plus storage overages, add-on subscriptions, and annual uplifts compound to 30–40% above sticker price.
  • Workflow Rules and Process Builder are deprecated, forcing all orgs onto Salesforce Flow — a migration task that catches many teams by surprise.
  • Steep administrative complexity: meaningful configuration requires a dedicated Salesforce admin or consultant.
  • API rate limits are edition-gated (100k/day base for Enterprise) and easily exhausted by large historical imports without throttling.
  • Data export is exportable via Data Loader but preserving relationship integrity across 30+ objects requires careful ETL sequencing.

Most Zinc-to-Salesforce migrations complete in 48–72 hours of clock time for under 50,000 candidate records. Larger organizations with 500,000+ records or complex custom object structures (nested employment histories, multi-step onboarding sequences) extend to 5–10 days. The longest planning step is designing the Salesforce custom schema — custom objects and fields must be created before data can be validated. FlitStack AI sequences the migration so schema setup and API extraction run in parallel where possible, compressing the overall timeline.
