Five Capacity Planning Tools for Teams That Have Outgrown Spreadsheets

Teams that have outgrown spreadsheets now have five credible capacity-planning options: Float, Runn, Resource Guru, Resource Management by Smartsheet and Kantata. All five remain available in 2026, but they solve different versions of the problem—from straightforward scheduling to enterprise-wide staffing and financial forecasting.

The important change is not simply a newer shortlist. Modern products increasingly combine live availability, tentative demand and utilization data, while broader platforms connect staffing to project and financial management. A June 2026 comparison of capacity-planning platforms places the five products in distinct purpose-built, enterprise work-management and professional-services categories, which is a more useful distinction than ranking them by feature count alone.

What a capacity planning tool must show

A team cannot plan capacity from assigned tasks alone. It needs a consistent calculation of supply—the working time actually available after part-time schedules, leave, holidays and existing allocations—and a comparable view of demand from confirmed and probable work.

The minimum useful system should therefore reveal remaining capacity and overallocation across a future date range. Skills, roles and location filters become important when availability alone cannot determine who is suitable. Tentative projects or placeholders matter when sales opportunities must influence hiring and staffing decisions before contracts are signed.

Utilization is related but not interchangeable with capacity. Utilization describes how available time is allocated, often with billable and non-billable categories; capacity asks how much work the team could realistically accept. A tool that reports last month’s utilization without displaying next quarter’s demand will not answer whether another project can be delivered.

The five strongest options for different teams

1. Float: the clearest live scheduling choice

Float is the most direct fit for teams that want a shared visual schedule without adopting a complete professional-services platform. Its central schedule brings people, projects and availability together, with allocations expressed as hours or percentages and adjustable by dragging, extending, splitting or reassigning work.

The product calculates capacity from standard working time, approved leave, public holidays and existing project allocations. According to Float’s April 2026 scheduling documentation, the same view exposes utilization, unscheduled capacity and overtime, while filters and saved views can narrow the plan by person, department, tag or project.

Best for: agencies, studios and delivery teams that need planners to rebalance work frequently. Its strength is operational clarity; organizations seeking an extensive PSA suite may need deeper finance and workflow functions elsewhere.

2. Runn: the best option for tentative demand

Runn is particularly useful when the planning question is not merely “Who is free?” but “What happens if this pipeline work becomes real?” Capacity charts combine availability, workload and utilization, while tentative projects allow planners to explore the effect of possible work before committing the team.

Runn’s current capacity-planning page confirms that its scenario workflow can model effects on capacity, timelines, delivery and pipeline. Placeholders reserve demand before named people are assigned, and availability calculations account for time off and public holidays.

Best for: consultancies and growing project organizations that need to compare confirmed delivery with probable future demand. Teams should evaluate how its scenario limits, reporting controls and integrations align with their chosen plan before purchase.

3. Resource Guru: straightforward scheduling with clash control

Resource Guru suits teams that want a more focused booking system. Its visual schedule, tentative bookings and capacity heatmaps support day-to-day allocation, while clash management can divert a booking to a waiting list when the requested person lacks sufficient availability.

That waiting-list model creates an explicit queue of unresolved demand instead of silently accepting a double booking. It is valuable for small agencies, production teams and organizations that schedule not only people but also shared equipment or rooms. Reporting depth varies by plan, so buyers should distinguish the scheduling functions they need from the utilization analysis they expect.

Best for: smaller teams whose immediate problem is preventing booking conflicts and making upcoming gaps visible. It is less suitable when capacity decisions must sit inside a large project-finance or portfolio-governance system.

4. Resource Management by Smartsheet: capacity inside a wider work system

Resource Management by Smartsheet is the logical candidate for organizations already coordinating projects in the Smartsheet environment. It extends planning beyond individual project sheets through a resource database, percentage-based allocations, time tracking and reporting across multiple initiatives.

Its advantage is organizational context: roles, disciplines, skills and part-time availability can inform staffing decisions while project owners retain views of their own work. The trade-off is commercial and operational complexity because Resource Management is positioned as an additional product rather than a lightweight standalone calendar.

Best for: larger organizations that already use Smartsheet and need capacity information to span many projects. A pilot should verify data synchronization, permissions and ownership of cross-project allocation changes.

5. Kantata: capacity tied to professional-services economics

Kantata addresses a broader problem than scheduling. Its professional-services platform combines resource planning with project management, financial management, business intelligence and workflow automation. That scope lets a services business examine staffing alongside billable work, project costs and revenue rather than treating available hours as the only constraint.

The breadth also changes the implementation burden. Smaller teams seeking a quick visual roster may find the platform excessive, while a complex consultancy may value the ability to connect resource supply, project delivery and commercial performance. Public comparison material does not provide a simple self-service price, so procurement should include a scoped demonstration and implementation discussion.

Best for: established professional-services organizations that need capacity planning inside a full operational and financial system.

How to choose without running five full trials

Begin with one decision the software must support. Examples include accepting a proposed project, resolving next month’s skill shortage or deciding whether a contractor is required. Build a small evaluation dataset containing real working schedules, leave, confirmed allocations and at least one tentative project.

Then ask each shortlisted product to produce the same answers:

• How many hours remain by role or skill during the target period?
• Which people are overallocated after leave and holidays are included?
• How does probable pipeline work change the result?
• Can a planner reassign work without losing the original project context?
• Who can edit capacity assumptions, and who can only view them?

Use Float or Resource Guru first when the central need is an understandable shared schedule. Prefer Runn when scenario planning and unnamed future demand are decisive. Resource Management by Smartsheet makes more sense when Smartsheet is already the operational hub, while Kantata belongs on the shortlist when staffing decisions must connect directly to professional-services finances.

The spreadsheet is not the benchmark

A spreadsheet remains useful for defining the model because its formulas expose assumptions. It becomes risky as the operating system for capacity when leave, allocations and pipeline changes arrive through different owners and must be reconciled manually.

The winning tool is therefore not the one with the longest feature list. It is the product that keeps supply and demand current, makes conflicts visible early and matches the organization’s decision horizon. For a small team that may be a clear weekly schedule; for a consultancy, it may be a scenario that connects next quarter’s pipeline to skills, utilization and project economics.
