Overview
Moving from Tender Support to Zendesk is a migration from a platform without a public API to one of the most thoroughly documented helpdesk APIs in the industry. Tender Support exports its data as admin-initiated CSV or JSON bulk downloads; Zendesk accepts imports via its REST API at 200 requests per minute on Team and 700 on higher tiers. We bridge that gap by validating each Tender Support export with row-count reconciliation, normalizing the flat-label vocabulary into Zendesk Tags (merging duplicates and applying a documented mapping), and detecting internal notes by inspecting the message_type or status column in the raw export before applying the correct private-comment flag in Zendesk. SLA Policies, Workflows, and Knowledge Base content are not present in Tender Support's data model and do not require migration; we document this explicitly so the customer knows what must be configured fresh in Zendesk. Custom Ticket Fields map directly where field types are compatible, and we flag any unsupported type for manual Zendesk field creation before import.
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 Tender Support object lands in Zendesk, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Tender Support
Ticket
Zendesk
Ticket (Request)
1:1Tender Support Tickets map directly to Zendesk Tickets. The ticket subject becomes the Zendesk subject field, body maps to the initial comment, status maps to the corresponding Zendesk status (open, pending, solved, closed), and priority maps from Tender Support priority to Zendesk priority. We preserve the original Tender Support ticket ID as an external_id field in Zendesk so agents can reference legacy ticket references in customer communications. Open and closed tickets migrate in full with their full conversation timeline.
Tender Support
Customer
Zendesk
User (End User)
1:1Tender Support Customer records map to Zendesk End User records. The customer email address serves as the primary identifier and dedupe key during import. First name and last name map to Zendesk user fields; any customer metadata custom fields map to Zendesk user custom fields. If the customer has opted to use Zendesk Organizations, we match customer domain names to organization records and link users accordingly during import.
Tender Support
Agent
Zendesk
Agent
1:1Tender Support Agent accounts map to Zendesk Agent records. We resolve by email match against the destination Zendesk user table. Any Tender Support agent without a matching Zendesk user goes to a reconciliation queue for the customer's admin to provision before import resumes. Note that Zendesk Suite Team requires a minimum of 5 agents; Suite Growth and above allow smaller starting seats. The customer's admin configures agent roles (admin, agent, light agent) in Zendesk before migration.
Tender Support
Label
Zendesk
Tag
lossyTender Support's flat label list maps to Zendesk Tags. We deduplicate and normalize the label set during the mapping phase, grouping semantically identical or overlapping labels into a single Zendesk Tag and documenting the mapping so the customer can audit which labels were merged. Zendesk auto-assigns tags from custom field dropdown options; we configure this behavior during schema setup so future tickets inherit tags from field selections. Any label with no equivalent in Zendesk is flagged as unmapped with a recommendation for manual tag creation or discard.
Tender Support
Attachment
Zendesk
Attachment
1:1File attachments on Tender Support ticket messages are referenced by URL in the export. We download each attachment to local storage during migration, preserving original filenames and MIME content types, then re-upload to the corresponding Zendesk ticket comment via the Zendesk Attachments API. Attachments over Zendesk's file size limits (20 MB per file on most tiers) are flagged for the customer to handle as external links or file-server storage.
Tender Support
Custom Ticket Field
Zendesk
Custom Ticket Field
1:1Tender Support custom ticket fields map to Zendesk ticket custom fields where field types are compatible. Text fields map to text, number fields to integer, date fields to date, and dropdown fields to Zendesk dropdown or tag fields. We discover all active custom fields during discovery, validate their types against Zendesk's supported field type list, and flag any unsupported type (such as Tender Support-specific field types with no Zendesk equivalent) for manual field creation in Zendesk before the migration runs. Zendesk's field key naming convention requires lowercase alphanumeric characters with underscores; we transform source field keys to comply.
Tender Support
Internal Note
Zendesk
Private Comment
1:1Tender Support messages marked as internal notes map to Zendesk private comments. We inspect the message_type or status column in the Tender Support export to identify internal notes and apply the public=false flag during import. If the export format omits this signal and internal notes appear as regular message rows, we flag those records for manual review before committing the import. The original internal note author and timestamp are preserved on the Zendesk private comment.
Tender Support
SLA Policy
Zendesk
SLA Policy
1:1Tender Support does not have a native SLA policy object or first-response and resolution-time tracking feature. No SLA data exists to migrate. If the customer requires SLA policies in Zendesk, these must be configured fresh post-migration. We deliver a written inventory of recommended SLA Policy conditions, metrics, and targets based on the customer's stated SLA commitments so the Zendesk admin can implement them without relearning requirements.
Tender Support
Workflow
Zendesk
Trigger or Automation
1:1Tender Support does not expose a workflow automation engine via its API. Any rule-based ticket routing, auto-assignment, or triggered actions configured in Tender Support are not exportable and are not migrated. We do not rebuild these as Zendesk Triggers or Automations within the migration scope. We deliver a written inventory of any Tender Support routing rules or auto-assignments the customer describes during discovery, with recommended Zendesk Trigger or Automation equivalents for the customer's admin to implement post-migration.
Tender Support
Knowledge Base
Zendesk
Guide Article
1:1The Tender Support product does not include a built-in knowledge base or self-service portal. No knowledge base content exists in standard Tender Support ticket exports to migrate. If the customer has external KB content (wikis, documentation sites, FAQ pages) they wish to import, we handle those as separate content migration work outside the ticket migration scope. Zendesk Guide must be activated by the account owner before article import; we confirm Guide activation status before the import phase.

Migration approach
Discovery and export validation
We audit the Tender Support instance for all active ticket fields, custom field types, label values, agent accounts, and attachment references. We request an admin-initiated bulk CSV or JSON export and validate the row count against the Tender Support admin interface. We identify the message_type or status column used to distinguish internal notes and flag any export format anomalies. We document the customer's SLA commitments, routing practices, and any external KB content as input for the post-migration configuration handoff.
Label normalization and field mapping design
We deduplicate and normalize the Tender Support label set, grouping semantically identical labels into Zendesk Tags and documenting the mapping. We map each Tender Support custom ticket field to a corresponding Zendesk ticket custom field by type compatibility, flagging any unsupported field types. We design the Zendesk tag-from-dropdown configuration so future tickets inherit tags from field selections. The mapping document is reviewed and signed off by the customer's admin before import begins.
Zendesk workspace preparation
We confirm that Zendesk Guide is activated (required for article import if applicable) and configure the initial tag set, custom ticket fields, and user accounts matching the Tender Support agent roster. We create a reconciliation queue for any Tender Support agent without a matching Zendesk user. If the customer uses Zendesk Organizations, we configure the organization schema and matching rules before the user import phase.
Attachment download and staging
We extract all attachment URLs from the Tender Support export, download each file to local staging storage preserving original filenames and content types, and organize them by ticket ID for re-upload during the import phase. Files exceeding Zendesk's 20 MB per-attachment limit are flagged for the customer to handle as external links. We validate download completeness with a file count and total size reconciliation against the export manifest.
Zendesk import in dependency order
We import data in dependency order: Users (from Tender Support Customers), then Agents, then Tickets (with conversation threads, private comments, and attachment re-uploads), then Tags (applied to tickets post-insert). Internal notes are imported with the public=false flag using the visibility signal identified during discovery. Custom field values are inserted after base ticket records are committed. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and handoff
We freeze Tender Support writes during cutover, run a final validation against the export row counts, and confirm ticket attachment completeness. We deliver the SLA Policy configuration guide, the Trigger and Automation inventory (for Tender Support routing rules), and the label-to-tag mapping document to the customer's admin team. We support a 48-hour post-cutover window for reconciliation issues. SLA policies, Triggers, Automations, Macros, and Zendesk Guide KB articles are not migrated; we deliver written recommendations for each and the customer's admin implements them as a post-migration configuration step.
