Overview
Moving from TimeLog to Trello is an architectural step-down, not a lateral switch. TimeLog is a professional services automation platform combining time tracking, project management, resource planning, and invoicing in one system. Trello is a Kanban-based task management tool with boards, lists, and cards at its core. We map what can be mapped—Projects to Boards, Activities to Cards, Employees to Members, and Time Entries as card metadata—and we explicitly document what cannot migrate: Invoices, Expenses, Rates, Salary Administration, and Reporting. The migration gap is not a migration failure; it is a structural difference between a PSA and a task board. We help customers understand this boundary before any data moves, so finance and operations teams can plan the billing and payroll work that will continue to live elsewhere after cutover.
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 TimeLog 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.
TimeLog
Project
Trello
Board
1:1TimeLog Projects map to Trello Boards. We preserve the project name as the board title, project status (Active/Completed/On Hold) as board star or archive, and the project start and due dates as card due dates on the first imported card. The project description maps to the board description field. Trello does not support nested sub-projects, so multi-level project hierarchies in TimeLog flatten into a single board level and are documented for manual restructuring post-migration.
TimeLog
Activity
Trello
Card
1:1TimeLog Activities map to Trello Cards. Each Activity name becomes a card title, the Activity description maps to the card description, and the Activity status (Active/Completed) maps to card archive state or a label. The billable/non-billable flag becomes a Trello label (e.g., 'Billable' or 'Non-Billable'). The Activity budget type (fixed-price or time-and-material) is preserved as a card label, though the budget amount itself has no Trello field to map to. Customers should note that budget tracking requires a separate financial system after migration.
TimeLog
Time Entry
Trello
Card Metadata (Power-Up)
lossyTimeLog Time Entries do not have a native Trello equivalent. We migrate the total logged hours per Activity as a card label (e.g., 'Logged: 14.5h') and per employee as a checklist item for reference. For paid-tier migrations, we document the Power-Up to use for ongoing time tracking (Time Tracking & Reporting Power-Up or a third-party like Planyo or Toggl Button integration). Historical time entry data is preserved as card metadata and exported as a CSV alongside the board migration for any time-and-billing reconciliation needed after cutover.
TimeLog
Employee
Trello
Workspace Member / Card Assignee
1:1TimeLog Employees map to Trello Workspace Members. We use the employee's email address as the Trello account identifier. Board membership is granted based on which projects the employee was assigned to in TimeLog. Card assignment in Trello maps to the employee's activity assignments in TimeLog. Trello does not support employee roles, departments, or billing rates, so these are preserved in a CSV export alongside the migration for reference. Salary data is not migrated because Trello has no payroll object.
TimeLog
Customer
Trello
Board Label or Card Label
lossyTimeLog Customers map to Trello in one of two ways depending on migration scope. For small customer lists, we create a Trello label per customer (e.g., 'Client: Acme Corp') and apply it to all cards within the customer's project board. For larger customer lists, we create a separate Customers board with a card per customer, and the original project board links are documented for reference. Customer contact details (address, billing currency) have no Trello field and are included in the customer CSV export.
TimeLog
Invoice
Trello
Not Migrated (External Documentation)
1:1TimeLog Invoices have no Trello equivalent. Invoice headers, line items, amounts, and payment status are exported as a structured CSV file and delivered alongside the board migration. Customers are responsible for migrating invoices to a dedicated billing platform (e.g., FreshBooks, QuickBooks, Zoho Invoice) if they require an ongoing invoicing system. We document the invoice-to-board association so that the project context for each invoice is preserved in the CSV.
TimeLog
Expense
Trello
Not Migrated (External Documentation)
1:1TimeLog Expense records (amount, date, category, billable flag, project association) have no Trello equivalent. We export all Expense records as a CSV file linked to the corresponding project board. Customers moving from TimeLog to Trello should plan to manage expense tracking in a separate tool (spreadsheet, dedicated expense app, or accounting software) post-migration.
TimeLog
Rates and Price Lists
Trello
Not Migrated (External Documentation)
1:1TimeLog maintains employee rates, activity rates, and customer-specific pricing that underpin its billing model. Trello has no rate or pricing object. We export the full rate structure as a CSV linked to the activity mapping so that the billable rate history is available for reference if the customer implements billing in a separate system. Rate migration to a billing platform is outside Trello migration scope.
TimeLog
Resource Allocation
Trello
Card Assignment
1:manyTimeLog resource allocations (employee-to-project hours or percentage assignments) map to Trello card assignments. An allocation of an employee to a project becomes that employee being added as a member to the relevant project board and assigned to the corresponding cards. Trello does not support capacity planning, utilization dashboards, or conflict detection for overlapping allocations; these capabilities require a dedicated resource management tool post-migration.
TimeLog
Custom Fields (Project/Activity)
Trello
Custom Fields Power-Up
lossyTimeLog custom fields on Projects and Activities migrate to Trello's Custom Fields Power-Up where field types are compatible (text, number, date, dropdown). Trello's Custom Fields Power-Up is available on Standard ($5 per user) and above. Custom field definitions are extracted during discovery, and values are mapped to the equivalent Trello field type. Fields with data types not supported by Trello (e.g., complex picklists, calculated fields, multi-currency) are flagged and exported as CSV alongside the migration.
TimeLog
Salary Administration
Trello
Not Migrated
1:1TimeLog Salary Administration (compensation history, effective dates, payroll data) is tier-gated and may not exist in all TimeLog accounts. Salary data is not migrated because Trello has no payroll object. If the customer requires ongoing payroll management, they should maintain salary administration in a dedicated HR or payroll system. Salary data, if present, is exported as a separate HR CSV outside the Trello migration scope.
TimeLog
Reporting Data
Trello
Not Migrated
1:1TimeLog Reporting views are generated dynamically from transactional data and are not exportable as report definitions or saved configurations. We do not migrate report definitions. The underlying transactional data (Projects, Activities, Time Entries) migrates to Trello, and customers can rebuild reports in Trello Power-Ups (Blue Cat Reports, Dashcards) or in a separate analytics tool. A written inventory of every TimeLog report definition is delivered as a reference document for manual rebuild.

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.
TimeLog gotchas
Tier-gated features create migration scope ambiguity
Fixed-price vs time-and-material billing requires rate mapping
Custom fields schema differs from standard object export
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 scope confirmation
We audit the source TimeLog account across tier (Starter/Professional/Enterprise), active projects, activity count, employee list, time entry volume, and customer count. We specifically query for custom field definitions, archived projects, and any tier-gated objects (Salary Administration) that may or may not be present. We confirm whether the customer uses fixed-price or time-and-material billing at the Activity level, as this affects label taxonomy in the destination. The discovery output is a written migration scope listing every object that migrates, every object that exports as CSV, and every object that has no destination.
Label taxonomy design and workspace mapping
We design the Trello label structure before migration begins. This includes labels for customer names (if using label-based customer tracking), billing status (Billable/Non-Billable), project status (Active/Completed/On Hold), and billing type (Fixed-Price/Time-and-Material). We map TimeLog Projects to Trello Workspaces or Boards depending on whether the customer's project count justifies a multi-workspace structure. Label design is validated against the expected card count to ensure label filters remain useful at scale.
Employee-to-member provisioning and CSV preparation
We extract all TimeLog Employees and map them to Trello Workspace Members by email. We prepare the customer CSV (with contact details and billing address), the invoice CSV (with line items and payment status), the expense CSV, and the rate CSV for separate delivery. Board membership is assigned based on project-employee associations in TimeLog. Any TimeLog employee without an email address (system records, inactive accounts) is flagged for the customer's admin to resolve before member provisioning.
Board and card migration with metadata enrichment
We migrate TimeLog Projects to Trello Boards and Activities to Cards. Each card receives the Activity name as title, description, due date (from the activity deadline), billing label, customer label, and a checklist entry for historical hours logged (from TimeLog Time Entries). Custom field values migrate to the Custom Fields Power-Up where data types are compatible. Financial objects (Invoices, Expenses, Rates) are not inserted into Trello but are exported as structured CSVs linked to the corresponding project board.
Post-migration documentation and billing handoff
We deliver the migrated Trello workspace alongside three separate CSV packages: the customer contact export, the invoice and expense export, and the rate schedule export. Each CSV is linked to its source TimeLog project so that the customer can import billing data into a dedicated invoicing platform (FreshBooks, QuickBooks, Zoho Invoice) independently of the Trello migration. We provide a written board structure guide documenting which boards correspond to which TimeLog projects, which labels correspond to which billing types, and which Power-Ups the customer should install for ongoing time tracking.
Cutover and Power-Up configuration
We freeze writes in TimeLog during the cutover window, run a delta migration of any records created or modified since the initial migration, and then hand off the Trello workspace. We support a one-week hypercare window for reconciliation issues. We do not manage the customer's billing platform migration (invoicing software, payroll system) as part of the standard Trello migration scope; that is a separate planning conversation. Time tracking Power-Up installation and configuration is completed during the handoff phase for paid-tier destinations.
