Overview
Moving from WorkflowMax to Trello is a model-level migration: WorkflowMax is job-centric with quotes, costs, and invoices that feed into Xero accounting, while Trello is board-centric using Kanban cards, checklists, and labels to track work. There is no direct object equivalence for Quotes, Costs, Invoices, or Tax Codes in Trello — these require either a companion accounting tool or manual reference. We export WorkflowMax Clients as Board members and Jobs as Cards, splitting each job's Tasks into Checklist items with estimated hours recorded in the card description. Staff roles migrate as Board member profile fields. We flag the absence of a native WorkflowMax import API by using the built-in CSV export and mapping the output to Trello's REST API, and we plan around Trello's 300 operations per minute per token rate limit for bulk card creation. Workflows, job templates, and the Xero sync configuration do not migrate; we deliver a written inventory of these for the customer's admin to re-implement using Trello Automations or Butler.

Object mapping
Each row shows how a WorkflowMax object lands in Trello, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
WorkflowMax
Client
Trello
Workspace Member + Board (or Organization profile field)
1:1WorkflowMax Client records map to Trello Workspace Members with the client name stored as a custom field on a reference Board or as an Organization profile field in Enterprise tier. We export Clients as the first entity in migration order so that any downstream Job import can reference the correct Trello member or board owner. Clients without an email in WorkflowMax are assigned a placeholder Trello member with the contact name as display name.
WorkflowMax
Client Contact
Trello
Workspace Member
1:1WorkflowMax Contacts (separate from the Client record via the Generic - Contacts export) map to additional Workspace Members attached to the same Board as the parent Client. Postal address fields migrate as a card description note or a custom field if the destination Board uses the Custom Fields Power-Up. We deduplicate by email address to avoid creating duplicate Trello members for contacts who appear in both the Client and Contact exports.
WorkflowMax
Job
Trello
Card
1:1WorkflowMax Jobs are the primary migration unit and map directly to Trello Cards. Each Job's name becomes the Card title, description becomes the Card description (with any internal notes appended), Job State maps to a Label colour (e.g., Active=green, Cancelled=red, Completed=blue), and Start Date and Due Date map to Card due date fields. We use the Job UUID as a custom Card ID field for reconciliation after migration. Jobs without a Client are placed in a default onboarding or backlog Board.
WorkflowMax
Job
Trello
List (by job status)
lossyWe configure one Trello List per distinct WorkflowMax Job State (e.g., Quote, In Progress, On Hold, Completed, Cancelled). Lists are pre-created on each Board before Card migration begins. If WorkflowMax uses custom states beyond the platform defaults, we create matching custom Labels in addition to the status-based List distribution. List order is preserved from the migration scoping configuration.
WorkflowMax
Task
Trello
Checklist Item (on Card)
1:manyEach WorkflowMax Task belonging to a Job migrates as a Checklist item on the parent Card. Task estimated hours migrate as text appended to the checklist item name (e.g., '[Est. 4h]'). Billable flag maps to a separate 'Billable' Label applied to the Card. Staff assignment on the Task resolves to a Card member (mapped via the Staff object). If a Task has sub-tasks in WorkflowMax, we flatten the hierarchy into a nested Checklist structure within the parent Card. Tasks without a parent Job are held in a catch-all Backlog Card for manual reassignment.
WorkflowMax
Timesheet
Trello
Card Description update or Activity Log Power-Up
1:1Timesheet entries (staff, date, hours, billable flag, cost rate) are aggregated per Job per staff member and written into the Card description as a structured summary table. Because Trello has no native time tracking object, we store the most recent 12 months of timesheet data in the Card; older historical timesheets are exported to a CSV delivered alongside the migration for reference in a connected time-tracking tool. We flag in the migration report which records contain manually entered hours (a known WorkflowMax pain point) so the customer understands data quality in the destination.
WorkflowMax
Cost
Trello
Card Custom Field or Description reference
1:1WorkflowMax Cost Admin records (products, materials, recurring expenses) are mapped to Card custom fields (if the destination Board has the Custom Fields Power-Up enabled) or appended to the Card description as a cost reference table. Cost codes and unit prices migrate as text values; cost totals per Job are summarised in the Card description for budget visibility. Trello has no native cost management or product inventory feature.
WorkflowMax
Quote
Trello
Card Attachment (PDF export) or Description
1:1WorkflowMax Quotes are exported as structured CSV records and converted to a Trello Card description section capturing line items, rates, and total values. If the customer has Quote PDFs stored in WorkflowMax, we flag these as manual download items and document the re-upload step to Trello Card attachments post-migration. Multiple Quotes per Job are stacked as separate description sections within the same Card, ordered by Quote creation date.
WorkflowMax
Invoice
Trello
Not migrated (accounting layer)
1:1WorkflowMax Invoices are tightly coupled to Xero and are not suitable for Trello as the destination. We export Invoice records as a reconciliation CSV (Invoice number, Job reference, client, total, status, Xero payment reference) and recommend the customer retains Xero as the source of truth for invoicing. The CSV is delivered alongside the migration package and the customer admin links the CSV to the relevant Trello Cards as a reference attachment. Cancelled invoices are exported separately and flagged in the reconciliation report.
WorkflowMax
Staff
Trello
Board Member
1:1WorkflowMax Staff records (name, role, cost rate, billing rate) map to Trello Board Members. We resolve Staff by email to create or match Trello Workspace accounts. Role and rate information are stored as Board member profile fields or as custom fields on a Staff Reference Card created in each Board. Staff without a Trello license are flagged in the migration report for the admin to provision before final cutover.
WorkflowMax
Custom Field (on Job)
Trello
Custom Field Power-Up field or Label
lossyWorkflowMax user-defined custom fields on Jobs are pre-created in Trello using the Custom Fields Power-Up before migration. Field type mapping: text fields become Trello text custom fields, numeric fields become Trello number custom fields, date fields become Trello date custom fields (with due date integration), and dropdown fields become Trello dropdown custom fields. Labels are used as a fallback for boolean custom fields if the Power-Up is not available on the destination plan.
WorkflowMax
Job Template
Trello
Board Template or Butler Rule
lossyWorkflowMax job templates define a standard task structure for recurring job types. We export template definitions including the task list, default values, and rates. In Trello, we replicate these as Board Templates (one Board per template type) with pre-populated Lists and a sample Card showing the intended checklist structure. For template-based automation (e.g., auto-assign staff when a Card enters a List), we document the Butler Rule configuration as part of the migration handoff rather than creating it as live rules.
WorkflowMax
Tax Code
Trello
Not migrated
1:1WorkflowMax Tax Codes used in quotes and invoices have no Trello equivalent. We export Tax Codes as reference data in the migration package CSV so that the customer can cross-reference them if they connect Trello to an accounting tool. No destination-side configuration is required.
WorkflowMax
Document and Attachment
Trello
Not migrated
1:1WorkflowMax job documents and file attachments cannot be exported via the API or built-in export (confirmed platform limitation with documented bugs around documents not appearing in job tabs). We instruct the customer to manually download their document library from WorkflowMax before the migration window and plan a manual re-attachment step in Trello after cutover. This step is documented in the migration runbook and is outside the automated migration scope.

Pair-specific challenges
Migration approach
Scoping and WorkflowMax CSV export profiling
We audit the source WorkflowMax instance: record counts per object (Clients, Contacts, Jobs, Tasks, Timesheets, Costs, Quotes, Staff, Custom Fields), job template count and structure, active vs archived job ratio, and any custom field definitions on Jobs. We run the built-in CSV export wizard for each data type and profile the output for data quality issues including missing required fields, duplicate UUIDs, orphaned Contacts without a parent Client, and timesheet entries with large discrepancies between entry date and work date. The scoping output is a written migration plan with the Board structure design, a data quality report, and a list of any records that require manual handling.
Board structure design and Trello schema preparation
We design the Trello Board hierarchy based on the WorkflowMax Client list: each major Client becomes a Board (or a List within a shared Board for smaller clients, per the customer's preference). We pre-create Lists per Job State, configure the Custom Fields Power-Up with fields matching the WorkflowMax custom field definitions, and add Labels for Job State colour coding and the Billable flag. If job templates exist, we create corresponding Board Templates. We also configure Trello Workspace settings (member invites, permission levels) to match the Staff roster.
Staff and member provisioning
We extract every distinct Staff record from WorkflowMax and attempt to match by email against existing Trello Workspace members. Staff without a matching Trello account are flagged in a provisioning report for the customer admin to create or invite before the migration phase. Owner reconciliation (WorkflowMax staff who own Jobs) maps to Card Members in Trello. We cannot create Trello accounts programmatically; the admin handles provisioning. Migration cannot proceed past Card creation until Staff member provisioning is confirmed.
Client and Contact migration
We migrate WorkflowMax Clients first as the foundational records. Each Client becomes a Trello Board or an Organisation entity (depending on the Trello plan). We then migrate Client Contacts as Workspace Members attached to the same Board or Organisation. Deduplication by email prevents duplicate member creation. The client address, billing code, and any client-level custom fields migrate as Board description fields or custom fields. Any Clients with no email contact are assigned a placeholder member with the contact name for board ownership.
Job and Task migration with checklist batching
We migrate WorkflowMax Jobs as Trello Cards in dependency order: Jobs without parent Jobs first, then Jobs with parent relationships resolved as Card labels or links. Each Card's name, description, due date, and custom fields are mapped during insertion. Tasks are migrated as Checklist items on the parent Card in a separate API batch after the Card is confirmed created. We implement a 20-second stagger between Card creation batches to respect Trello's rate limit of approximately 300 operations per minute per token. Any rate-limit 429 responses trigger an exponential backoff retry before the batch is re-submitted.
Timesheet, Cost, and Quote aggregation; document manual handoff
We aggregate Timesheet entries per Job and write a structured summary table to the Card description. Cost records are appended to the Card description or to a custom Cost custom field if the Custom Fields Power-Up is configured. Quotes are written as a structured section in the Card description; any Quote PDFs to be re-attached are documented in the migration runbook for manual re-upload. We deliver a standalone CSV of Invoice records for Xero reference and a separate CSV of Tax Codes as lookup data. We instruct the customer to manually download their WorkflowMax document library before the migration window and document the re-attachment step for Trello Card attachments post-cutover.
Cutover, validation, and template handoff
We freeze WorkflowMax write access during the cutover window, run a final delta migration of any records modified since the last batch, and then enable Trello as the system of record. We deliver a migration reconciliation report comparing record counts in WorkflowMax against record counts in Trello (Boards, Cards, Checklist items, Members). We deliver a separate inventory of Job Templates and recommended Trello Board Template equivalents, plus a Butler Rule design document for any template-based automation the customer wants to rebuild. We do not create live Butler rules or Trello Automations as part of the migration scope; that work is handled by the customer's admin using the handoff documentation.
