Overview
Moving from Paymo to Trello is a structural simplification. Paymo is a full project-management suite with task management, Gantt charts, per-task time tracking, client invoicing, per-project Custom Workflows, and workload scheduling; Trello is a Kanban-first board tool that covers tasks, checklists, and comments but requires Power-Ups for time tracking, calendar views, and custom fields. We map Paymo Projects to Trello Boards, Task Lists to Lists, and Tasks to Cards, preserving Custom Workflow statuses by creating equivalent List names per board. We do not migrate Gantt dependencies, time entries, invoices, estimates, or expenses as native Trello objects because Trello has no equivalent schema. We export these records to CSV and deliver them alongside the migration for the customer's admin to manage in a separate tool or via Trello Power-Ups. Paymo Automations and Project Templates do not migrate as automation code; we deliver a written inventory for manual rebuild in Trello Butler.

Object mapping
Each row shows how a Paymo 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.
Paymo
Project
Trello
Board
1:1Paymo Projects map directly to Trello Boards. Project name becomes Board name, and project-level metadata (status, client association, budget, hourly rate) migrates as Board description or as Custom Fields if the destination Trello workspace uses Premium. We create one Board per Paymo Project and preserve project ordering by appending Board position in the workspace. Archived Projects in Paymo map to Archived Boards in Trello if the workspace uses a Board archiving strategy.
Paymo
Task List
Trello
List
1:1Paymo Task Lists map to Trello Lists within the parent Board. The list order is preserved. If the Paymo project uses a Project Template, the template's Task List structure migrates as a new Board with identical List-Task scaffolding. Note that Trello Lists are board-scoped only; there is no cross-board List inheritance, so each Board gets its own independent List set.
Paymo
Task
Trello
Card
1:1Paymo Tasks map to Trello Cards within the parent List. Standard fields migrate: Task name to Card name, description to Card description, start/due dates to Card due date (a native Trello field), assignees to Card members, and priority to Card labels or Custom Field dropdown (Premium). Estimated hours do not have a native Trello equivalent; we export them to a CSV companion file alongside the migration. Subtasks in Paymo map to Card checklists in Trello.
Paymo
Custom Workflow (status column)
Trello
List (by status name)
lossyCustom Workflows introduced in March 2026 define per-project Kanban status columns. We map each project's unique workflow status set to Trello List names within that project's Board. If a status has no direct equivalent, we create a catch-all List (e.g., 'Miscellaneous') and flag it in the migration report for the customer's admin to rename or redistribute. Projects with no custom workflow map to default Lists (To Do, In Progress, Done) unless Paymo's project uses a built-in status set, which we convert to List names matching the source.
Paymo
Milestone
Trello
Card (milestone marker) or Checklist
1:1Paymo Milestones are tied to Task Lists, not individual tasks. We map each Milestone to a dedicated Card at the top of the corresponding List, titled with the Milestone name and marked with a milestone label or a Custom Field (Premium) to distinguish it from regular tasks. Milestone dates migrate to the Card's due date field. Trello does not support Gantt-view milestone display natively; the customer's admin must use a Power-Up like Chronogantt to render milestones on a timeline post-migration.
Paymo
Time Entry
Trello
Custom Field (Time Tracker Power-Up) or CSV export
1:1Time Entries linked to Tasks carry date, duration, billable flag, hourly rate, and description. Trello has no native time tracking field. We have two options: migrate time entry data as Custom Fields on the Card (Premium feature, limited to numeric or text format) or export to a CSV companion file keyed by Paymo Task ID. If the customer has the Time Tracker Power-Up active in their Trello workspace, we map entries to Power-Up time records linked by Card. Billable status and invoice linkage do not migrate because Trello has no invoicing module.
Paymo
Invoice
Trello
CSV export only
1:1Paymo Invoices are generated from Time Entries and carry client, line items, totals, tax, and payment status. Trello has no invoicing module and no equivalent object. We export invoices to a structured CSV file keyed by Paymo Invoice ID, client name, and the Paymo Project ID, so the customer's admin can import into an accounting tool (QuickBooks, Xero, FreshBooks) or keep as a financial record outside Trello. We flag any invoices with an Unpaid status for explicit attention during post-migration reconciliation.
Paymo
Client
Trello
Custom Field (Client) or Card label
1:1Paymo Clients are separate records linked to Projects and Invoices. Trello has no native client object. We map Clients to Trello by adding a Client Custom Field (Premium) to each Board or Card, or by prefixing Card names with the client name. If the workspace does not have Premium, we create a Client label per board and attach it to every card belonging to that client's project. We preserve the client billing contact as a text Custom Field if available.
Paymo
Estimate
Trello
CSV export or Custom Field
1:1Paymo Estimates are project-level financial approximations (available on Small Office and Business tiers) that can be converted to invoices. Trello has no estimate or budget-tracking object. We export estimates to a structured CSV file keyed by Paymo Project ID, with line item descriptions, quantities, unit prices, and totals. If the customer uses a Power-Up like Better Docs or a linked Notion workspace for project scoping, estimates can be attached as a linked document.
Paymo
Expense
Trello
CSV export
1:1Paymo Expenses are logged separately from time entries and carry amount, date, description, and billable status. Trello has no expense tracking module. We export expenses to a CSV file keyed by Paymo Project ID and task ID, preserving amount, currency, date, description, and billable flag. The customer's admin imports this into an expense management tool or accounting software post-migration.
Paymo
Project Template
Trello
Board Template (manual setup)
lossyPaymo Project Templates bundle a project structure including Task Lists, Tasks, and Workflows for reuse and are available on Small Office and Business tiers. Trello has a Board Templates feature but it does not include automation or workflow templates. We deliver a Board Template mapping document listing each Paymo template and its Trello Board Template equivalent, noting that the customer's admin must manually configure Lists, Custom Fields, and any Butler rules to replicate the template structure. Template migration is configuration, not data migration.
Paymo
Discussion (project comments)
Trello
Card Comments
1:1Paymo Discussions are project-level comment threads attached to Projects. Trello does not have a project-level comment thread; comments attach to Cards. We map Discussions to Card Comments by matching the discussion topic to the most relevant Card (or creating a dedicated 'Project Notes' Card with comments as a catch-all). Chronological order is preserved by setting comment timestamps. Discussion threads that reference multiple Tasks are split into Card-level comments with a reference header noting the original discussion context.
Paymo
User (assignee)
Trello
Board Member
1:1Paymo Users referenced as Task assignees map to Trello Board Members. We resolve assignees by email match against the destination Trello workspace. Any Paymo user without a matching Trello member is flagged in the reconciliation report for the customer's admin to provision. Inactive Paymo users are added as Board observers (read-only) if their historical assignments need to remain visible on Cards.
Paymo
Leave Planner
Trello
Not migrated
1:1Paymo Leave Planner records (Business-plan feature) manage employee time off and feed the workload scheduling view. Trello has no HR or absence management module. We do not migrate Leave Planner records to Trello. We export them to a CSV file keyed by user and date range, so the customer's HR admin can maintain the data in an HR tool or spreadsheet. The absence data is preserved and flagged as out-of-scope for the Trello migration.

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.
Paymo gotchas
Custom Workflows require plan-tier mapping
Milestone placement is tied to Task Lists, not tasks
Invoice export to QuickBooks requires manual client and item matching
Free and Solo plan limits restrict project and client counts
Ghost bookings and leave data are Business-plan gated
Trello gotchas
Billing model uses maximum seat quantity at term midpoint
Custom Field data historically stored in pluginData
API rate limits are token-gated and can block bulk migration
Guest-to-paid seat conversion triggers on multi-board membership
Automation command runs are capped per plan and overage triggers upgrade pressure
Pair-specific challenges
Migration approach
Discovery and workspace scoping
We audit the source Paymo account across plan tier, project count, Custom Workflow status sets per project, task volume, time entry count, invoice count, and active Project Templates. We pair this with a Trello workspace audit: current plan tier, active Power-Ups, Board count, and member structure. The discovery output is a written migration scope document listing every Paymo object and whether it maps to a Trello object, a Power-Up dependency, or a CSV export. We confirm the customer's Trello Premium status because it determines whether Custom Fields are available as a mapping target.
Schema design and List mapping
We design the destination schema in Trello. For each Paymo Project, we create a Trello Board. For each Paymo Task List, we create a Trello List within the corresponding Board. For Custom Workflows, we map each project's unique status set to List names, flagging any statuses without a close match. We configure Card labels for priority, client name (if not using Premium Custom Fields), and milestone markers. We set up Board members by matching Paymo assignee emails to Trello workspace members, flagging any unmapped users for the customer's admin to provision.
API-based migration and CSV export generation
We use the Trello REST API to create Boards, Lists, and Cards in dependency order: Boards first (one per Project), then Lists (per Task List), then Cards (per Task with parent List resolved). Assignees, due dates, descriptions, and labels migrate directly via API. Subtasks from Paymo migrate as Card checklists. After the API migration, we generate three CSV companion files: Time Entries (keyed by Task ID), Invoices (keyed by Invoice ID and Project ID), and Expenses (keyed by Project ID). Each CSV includes a migration record count reconciliation report.
Discussion and milestone mapping
We map Paymo Discussions to Card Comments by matching discussion topics to the most relevant Card or creating a dedicated Project Notes Card as a catch-all for discussions that reference multiple tasks. We map Paymo Milestones to dedicated milestone Cards with a milestone label, preserving the milestone name, date, and Task List association. Both mappings are reviewed by the customer's admin before the migration runs to confirm the assignment of discussions and milestone Cards to the correct parent.
Sandbox migration and reconciliation
We run a full migration into a Trello Workspace Sandbox (a separate workspace used for testing) using production-like data volume. The customer's project manager reconciles record counts (Boards in, Lists in, Cards in, Members assigned, Comments migrated), spot-checks 20-30 random Cards against the Paymo source for field accuracy, and reviews the CSV companion files for completeness. Any mapping corrections happen in the sandbox, not in production. This step is critical for Custom Workflow mapping review because each project's status set requires explicit admin sign-off.
Production migration and Automation rebuild handoff
We run the production migration into the live Trello workspace after sandbox sign-off. We freeze Paymo writes during cutover and run a final delta migration of any records modified during the window. We deliver the Trello Butler Automation inventory (from Paymo Automations and Project Templates) as a written document with each automation's trigger, conditions, and recommended Butler rule equivalent. We do not rebuild Paymo Automations as Trello Butler rules inside the migration scope; the customer's admin configures Butler post-migration using the handoff document. We deliver the CSV companion files for Time Entries, Invoices, and Expenses with a data dictionary so the admin can import into their chosen financial tool.
