# Gantt Chart Pro Q&A

Quick answers to the questions teams ask most about Gantt Chart Pro. If you are just setting up the app, start with the Gantt Chart Pro Get Started guide.

# Pricing and licensing

# What is the difference between Free and Premium?

Free includes the essentials: dependencies, notes, progress tracking, and column sorting. It is limited to 5 tasks (each with 1 subtask) and 3 participants per task. Premium adds unlimited tasks, subtasks, and participants, plus task colors, milestones, filtering, and exports (CSV, Excel, and PDF).

# Do all channel users need a license?

No. Only license the users who need Premium features. Unlicensed users can still use the tab within the Free limits.

# Where do I buy or manage licenses and invoices?

In the Teams-Pro Admin Center (opens new window), where you handle billing, seats, invoices, and cancellations.

# Features and usage

# Which export formats are supported?

CSV, Excel (.xlsx), and PDF. Exports are a Premium feature. Use CSV or Excel for data analysis, and PDF for a shareable snapshot.

# Can I control who edits the plan?

Yes. Set owners only or everyone in the tab permissions. Everyone in the channel can still view the timeline.

# Can I assign people to tasks?

Yes. Add participants to tasks so ownership is clear across the team. The Free plan allows up to 3 participants per task, and Premium removes that limit.

# Which features are Premium?

Task colors, milestones, and filtering are Premium. Sorting is available on every plan. On the Free plan, opening a Premium tool prompts you to upgrade.

# Does Premium change how big my plan can be?

Yes. Premium removes the limits on tasks, subtasks, and participants, so it suits larger projects.

# Access and external collaboration

# Are your apps restricted for external users?

Not by default. Access for guests and external users depends on your Microsoft 365 external collaboration policies in Teams. See the Microsoft guidance on how to communicate with users from other organizations (opens new window).

# Data, security, and privacy

# Where can I read about data security and privacy?

# Billing and payments

# Can I combine multiple subscriptions into one payment?

Yes. Move to a single subscription with the total number of licenses you need, then cancel the older individual subscriptions.

When we cancel the older subscriptions, any unused proration is lost and cannot be reinstated.

# How do I upgrade my subscription?

Use the Teams-Pro Admin Center (opens new window) to upgrade. If you were given a direct upgrade link, open it and complete checkout.

If you buy a single Premium seat, only the licensed user gets premium creation features. Other members can usually still view the results.

# How do I update my credit card?

  1. Open the Teams-Pro Admin Center (opens new window).
  2. Click your profile icon or name at the top right, then select Billing.
  3. Click Payment methods.
  4. Select Add payment method, enter your card and billing details, and click Save.

# Where can I download invoices?

  1. Open the Teams-Pro Admin Center (opens new window).
  2. Click your profile icon or name at the top right, then select Billing.
  3. Click Billing History.
  4. Click Download next to the invoice you need. The file downloads automatically.

You can also follow the step-by-step guide: How to download invoices (opens new window).

# Troubleshooting and support

# My app or tab is not opening in Teams (the title shows but it will not open, or it is missing on mobile).

This usually stems from tenant policies. Ask your IT team to check:

  • App registration disabled
  • Enterprise application disabled
  • A new or changed Conditional Access policy
  • Admin consent revoked
  • A tenant-wide setting disabled
