Overview

What this migration involves

Moving from TimeLog to Microsoft Project is a fundamentally asymmetric migration. TimeLog is a PSA platform built around billing, invoicing, and resource utilization for professional services firms; Microsoft Project is a scheduling and Gantt-chart tool built around task dependencies, resource leveling, and critical path analysis. We migrate the project structure (Projects → MS Project Projects, Activities → Tasks), and we roll up time-entry hours as task actuals so resource utilization reporting has a baseline in the destination. We do not migrate Invoices, Expenses, Rates, Salary Administration, or any billing-related data because these have no equivalent schema in Microsoft Project. We deliver a written inventory of billing relationships and resource rate structures that the customer's PMO rebuilds in Excel, Power BI, or a third-party resource management add-in. Microsoft Project Online carries a retirement deadline of September 30, 2026, which affects whether the destination is MS Project desktop, Project Server Subscription Edition, or Planner Premium.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

Why teams make this switch

Two sides of the same decision

Leaving

TimeLog logo

TimeLog

What's pushing teams away

  • Users report that the reporting interface has a steep learning curve, with multiple reports available but not all of them easy to navigate or find.
  • Integration limitations with other software are cited as a drawback, making it difficult to connect TimeLog with tools outside its native ecosystem.
  • Some users find the reporting features incomplete or lacking in certain areas, despite the volume of available reports.
  • Companies seeking to consolidate onto a different PSA platform often cite the desire for better third-party integrations as a reason for switching.

Choosing

Microsoft Project logo

Microsoft Project

What's pulling them in

  • Organizations already running Microsoft 365 and Azure AD adopt Microsoft PPM because it slots into existing identity, Teams, and SharePoint infrastructure without requiring a separate identity provider or SSO vendor.
  • Enterprise PMOs choose it for critical-path scheduling, baseline comparison, cross-project dependencies, and resource utilization reporting that standalone PM tools cannot replicate at this depth.
  • Project Online's integration with Power BI gives portfolio-level dashboards and cost-rollup reporting that satisfies executive governance requirements without third-party BI tooling.
  • Government, financial services, and healthcare organizations select it because FedRAMP, ISO 27001, and SOC 2 compliance certifications meet enterprise procurement requirements out of the box.
  • Large IT departments default to it as the market-leader in project portfolio management software, often driven by corporate licensing agreements that bundle it with other Microsoft 365 seats.

Object mapping

How TimeLog objects map to Microsoft Project

Each row shows how a TimeLog object lands in Microsoft Project, including any object-level transformations, lookup resolution, or schema-design dependencies.

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

TimeLog

Projects

maps to

Microsoft Project

Project

1:1
Fully supported

TimeLog Projects map to Microsoft Project files or Project Online Project entities. We migrate project name, status (Active/On Hold/Completed), planned start and end dates, and customer association as a text field or custom field. The project hierarchy (Projects containing Activities) becomes the top-level project in MS Project with Activities mapped as Tasks below it. Project-level custom fields migrate where field types are compatible with MS Project custom field data types (text, number, date, flag, outline code).

TimeLog

Activities

maps to

Microsoft Project

Task

1:1
Fully supported

TimeLog Activities map to MS Project Tasks. Each Activity's name becomes the Task Name, planned hours map to the Task field Baseline Work, and the Activity status maps to the Task Percent Complete or Status field. Activities with a fixed billing method retain that metadata as a custom Task field because MS Project has no native billing method attribute. The project-activity parent-child relationship is preserved as a Summary Task (MS Project) with child Activities as subordinate Tasks in the same project file.

TimeLog

Time Entries

maps to

Microsoft Project

Assignment Actual Work

1:many
Fully supported

TimeLog Time Entries aggregate by Activity and Employee. For each Activity (now a Task), we roll up all billable and non-billable time entries by date and map the sum to the Assignment's Actual Work field in MS Project, grouped by the assigned resource. The billable/non-billable flag from TimeLog is stored as a custom Assignment field or task-level flag. Historical timestamps are preserved so the time-phased distribution of actual work matches the original TimeLog data. MS Project requires a Resource assignment to exist before Actual Work can be logged, so we sequence the Employee-to-Resource migration before time-entry migration.

TimeLog

Employees

maps to

Microsoft Project

Resource

1:1
Fully supported

TimeLog Employees map to MS Project Resources. We migrate employee name, email, role, and department. The department maps to a Resource Group in MS Project, and the role maps to a custom Resource field. Employee billing rates from TimeLog do not map directly to MS Project resource cost rates because MS Project uses cost-rate tables for generic resource costing rather than customer-specific or activity-specific pricing; we store the original rate as a custom Resource field for reference and flag this for PMO reconciliation.

TimeLog

Customers

maps to

Microsoft Project

Custom Field (Project or Resource)

lossy
Fully supported

TimeLog Customers have no direct equivalent in Microsoft Project's schema. We map the customer name as a custom Project-level Text field (e.g., Custom Text1 = Customer Name) and store the customer ID as a lookup or outline code for reference. If the customer has a rate agreement that affects project billing, we note this in the billing reconciliation document for the customer's PMO to handle in a downstream finance system.

TimeLog

Invoices

maps to

Microsoft Project

None

1:1
Mapping required

TimeLog Invoices and Invoice Lines have no equivalent schema in Microsoft Project. MS Project does not support billing, invoicing, or accounts receivable tracking. We do not migrate Invoice records. We export a written summary of each Project's invoiced amount, payment status, and invoice number for the customer to reference outside MS Project, typically in a financial system or spreadsheet that the PMO maintains alongside the project schedule.

TimeLog

Expenses

maps to

Microsoft Project

Task Actual Cost

lossy
Fully supported

TimeLog Expense records map to MS Project Task Actual Cost where the expense is tied to a specific Activity. Expense amount, date, category, and billable flag migrate as a custom Task field (e.g., Custom Cost 1 = Billable Expense Total). Expenses not tied to a specific Activity are summarized at the Project level and stored as a Project-level custom cost field. MS Project's Actual Cost field calculates from resource rates and actual work; expense data from TimeLog that represents direct non-labor costs does not feed into this calculation automatically and requires manual reconciliation.

TimeLog

Resources (Allocations)

maps to

Microsoft Project

Resource Assignments

lossy
Mapping required

TimeLog resource allocations (employee assignments to projects by hours or percentage) map to MS Project Assignment records. Each allocation's planned hours or percentage becomes the Assignment's Planned Work or Units field. If the allocation is a percentage-based booking in TimeLog, we convert to hours using the project's defined work hours before mapping to MS Project's Assignment Units. We flag any TimeLog allocations that use percentage-based booking without a defined project duration because MS Project Assignment Units require a schedule context to resolve.

TimeLog

Rates and Price Lists

maps to

Microsoft Project

Resource Cost Rate Tables

lossy
Mapping required

TimeLog maintains employee rates, activity rates, and customer-specific pricing tiers. MS Project Resource cost rate tables (Cost Rate A through E) store resource per-hour costs, but they do not support customer-specific or activity-specific rate overrides at the project level. We migrate employee rate data into the MS Project Resource Cost Rate Table (Cost Rate A) as the default rate, and we document the activity-specific and customer-specific rate structures in the billing reconciliation inventory for the customer to handle in their finance system or Power BI reporting layer.

TimeLog

Salary Administration

maps to

Microsoft Project

None

1:1
Mapping required

Salary Administration is a tier-gated feature in TimeLog (Professional and Enterprise tiers only). Salary data, compensation history, and effective dates have no equivalent in Microsoft Project. We do not migrate salary records. If the customer is on a TimeLog tier that includes Salary Administration and wants to preserve this data, we confirm during scoping whether it should be exported to a separate HR system or financial system rather than the project schedule.

Pair-specific challenges

  • Billing model has no Microsoft Project equivalent

    TimeLog generates invoices from time entries, fixed-price Activity budgets, and expense records tied to Customers. Microsoft Project has no invoicing, accounts receivable, or billing schema. We do not migrate Invoices, Invoice Lines, or rate-based pricing from TimeLog. The customer must identify their post-migration billing system of record (ERP, financial system, or manual process) and we provide a written export of every project's invoiced total, outstanding balance, and payment status for that team to reconcile. Migrations that assume billing data will be visible in MS Project after cutover will find it absent.

  • Time-entry rollup to task actuals requires resource pre-provisioning

    Microsoft Project requires a Resource assignment to exist on a Task before Actual Work can be logged against that Task-Resource pair. TimeLog time entries are logged by Employee against Activity without an explicit scheduling assignment. We resolve this by migrating Employees to Resources first, then mapping Activities to Tasks, then rolling up time entries by Employee and Activity into Assignment Actual Work. If any Employee has time entries but no corresponding Resource in the destination, the entries for that Employee are held in a reconciliation queue until the Resource is provisioned. Skipping this sequencing results in orphaned actuals with no task attachment.

  • Fixed-price Activity budgets do not map to MS Project cost fields

    TimeLog Activities using fixed-price billing carry a budget amount that represents the contract value for that deliverable. MS Project uses resource cost rate tables and actual work to compute Estimated Cost at Completion, which is a calculation from rates and hours rather than a fixed contract value. We store the TimeLog fixed-price budget as a custom Project or Task field (Custom Cost) and flag it for PMO reconciliation. The delta between the fixed budget and MS Project's earned value calculation requires manual interpretation by the project manager.

  • Calendar and scheduling conflicts cause date drift

    TimeLog and Microsoft Project use separate calendar configurations. Tasks scheduled from TimeLog start and end dates may shift in MS Project if the project's default calendar (Standard 40-hour week) conflicts with the hours-per-day settings TimeLog used for Activity planning. We recommend validating calendar settings in MS Project before importing the project schedule. Tasks with fixed constraints in TimeLog (Must Start On, Must Finish On) may not translate cleanly to MS Project's constraint types and can cause unexpected schedule recalculation on import.

  • Custom fields on Projects and Activities require post-migration validation

    TimeLog allows custom fields on Projects and Activities. We extract custom field definitions during discovery and map them to equivalent MS Project custom field types (Text, Number, Date, Flag, Outline Code) where the data type is compatible. Custom fields with unsupported data types or complex lookup structures are flagged in the migration report for manual post-migration review. MS Project custom fields do not support multi-select, currency with decimal precision matching, or long-text with formatting, and data loss or truncation may occur for these field types.

Migration approach

Six steps for a successful TimeLog to Microsoft Project data migration

  1. Discovery and tier confirmation

    We audit the source TimeLog account to confirm the active pricing tier (Starter/Professional/Enterprise) because salary administration and advanced automation features are tier-gated and may not exist in the account even if the object schema is present. We extract Projects, Activities, Time Entries, Employees, Customers, and any custom fields. We ask the customer to confirm whether Salary Administration data exists and whether it should be exported separately or excluded. We also confirm the destination: MS Project desktop (MPP files), Project Online (before September 2026 retirement), Project Server Subscription Edition, or Planner Premium with Gantt support. The discovery output is a written migration scope document with record counts per object and a destination recommendation.

  2. Employee-to-Resource provisioning

    We migrate TimeLog Employees to MS Project Resources before any task or time-entry migration. Each Employee becomes a Resource with Name, Initials, Type (Material or Work), Group (from Department), and a custom field carrying the Employee's role. The employee's billing rate from TimeLog is stored in the Resource's Cost Rate Table (Cost Rate A) as a reference value. Any Employee in TimeLog that does not yet have a corresponding Resource in the destination is flagged for the customer's admin to provision before time-entry migration proceeds.

  3. Project and Activity mapping to Tasks

    We map TimeLog Projects to MS Project project files or Project Online project entities. Activities nested under each Project become Tasks in the corresponding MS Project project, preserving the hierarchical structure as Summary Tasks and subordinate Tasks. Activity planned hours map to Task Baseline Work. Activity status maps to Task Percent Complete. Fixed-price billing method on Activities is stored as a custom Task field. We validate calendar settings before import to catch any hours-per-day mismatches that would cause date drift on scheduled Tasks.

  4. Time-entry aggregation and Actual Work migration

    We aggregate TimeLog time entries by Employee, Activity, and date. Each aggregation maps to an MS Project Assignment (Task-Resource pair) with the summed hours as Assignment Actual Work. The billable/non-billable flag from TimeLog is stored as a custom Assignment field. We run this migration phase after Resources and Tasks are in place so that the parent-record references are satisfied at insert time. Any time entries referencing an Activity that was not migrated (excluded during scoping) are summarized in a separate exception report.

  5. Expense and allocation migration

    TimeLog Expenses tied to specific Activities migrate as custom Task cost fields. Expenses not tied to an Activity are summarized at the Project level. Resource allocations (employee bookings to projects) migrate as MS Project Assignment Planned Work or Units values. We document any percentage-based allocations that could not be fully resolved without a defined project schedule duration.

  6. Cutover, validation, and billing handoff

    We freeze TimeLog writes during cutover, run a delta migration of any records modified during the migration window, then hand the MS Project destination to the customer's PMO. We deliver the billing reconciliation inventory (invoiced amounts, payment status, rate structures by customer and Activity) as a structured export for the customer's finance team. We do not migrate Invoices, Salary Administration, or billing automation. We support a one-week post-migration window to resolve record-count discrepancies and field-level validation failures. Rebuilding any PSA-style billing views in MS Project requires a separate PMO or BI engagement.

Platform deep dives

Context on both ends of the pair

  • Integrates time tracking, project management, resource planning, and invoicing in one platform
  • Intuitive user interface praised across multiple review sources
  • Responsive customer success team with rapid inquiry response times
  • Supports both time-and-material and fixed-price billing models
  • Regular feature releases based on user feedback and requests

Weaknesses

  • Reporting interface is difficult to navigate with a steep learning curve

Strengths

  • Deep critical-path scheduling with baseline comparison and cross-project dependency tracking unmatched by lighter PM tools.
  • Native Azure AD authentication, Teams integration, and Power BI reporting sit on infrastructure enterprises already license and manage.
  • Enterprise governance controls including demand intake workflows, resource request approval, and portfolio-level capacity analysis.
  • Supports both Waterfall and Agile methodologies within the same project, accommodating hybrid delivery teams.
  • Scalable from Project Plan 1 for small teams to Project Server on-premises for regulated industries with strict data-sovereignty requirements.

Weaknesses

  • Ease-of-use scores trail the category average by a wide margin; onboarding friction frustrates new users consistently across G2 and Capterra reviews.
  • Pricing ranks 42nd of 49 tools in its category — the total cost of ownership including IT administration and training is rarely recovered for small or mid-market teams.
  • No built-in client portal, external stakeholder sharing, or proofing workflow, limiting use cases to internal PMO environments only.
  • The web interface (Project for the web / Planner Premium) has materially weaker constraint controls and resource auto-leveling than the Windows desktop client.
  • Project for the web is being consolidated into Microsoft Planner, creating uncertainty about which product tier will host project portfolio data long-term.

Migrations under 50 active projects and 5,000 Activities land between two and four weeks. Migrations with large time-entry histories (over 100,000 entries), multi-tier rate structures, or complex resource allocation rollups move to six to ten weeks because of the aggregation logic required to roll time entries into task actuals and the manual rate reconciliation work. The destination platform (MS Project desktop, Project Online, Project Server SE, or Planner Premium) also affects timeline because Project Online and Planner require Microsoft tenant-level provisioning before data can be imported.
