The search for capital planning software usually starts when the capex spreadsheets stop coping. Requests arrive in different formats, approvals get chased over email, and nobody can say with confidence how much capital is committed right now.

Moving off spreadsheets is worth the effort. According to McKinsey, a digitally enabled capital-investment-management system improves both financial results and the quality of decisions, and organisations that build one can see project and portfolio NPV rise by well over 10 percent within a year.

Finding the right system is the hard part. A typical online list of the best capital planning software puts capex software side by side with a construction planning tool, an FP&A platform, a facility management system and a public-sector budgeting tool. Each of them was built for a different purpose.

So the first question is what you need the software to do. Then you can compare vendors on how well their software meets those needs.

Know the categories

Which type of capital planning software do you need?

Capital planning software helps an organisation decide which capital investments to fund, in what order and within what budget, usually over several years. It sits between long-term capital strategy and the approval of individual projects, and ends in an approved capital plan. The trouble is that vendors use the term loosely, and search results mix it with capex software, capital project management software, FP&A tools and ERP modules. Each type answers a different question and is used by different people in your organisation. The table below shows which.

Types of capital planning software compared
Type of software	The question it answers	Who works with it
Capex software (capex management)	How does each investment move from request to approval, budget, spend and close-out under control?	Group business controllers, head of capex, project owners, CFO
Capital planning software	Which investments deserve capital, in which order, within which envelope, over the coming years?	CFO, FP&A, investment committee
Capital project management software	How does one large project get delivered on time and on cost?	Project controls, PMO, engineers on site
FP&A and EPM platforms	How do the P&L, balance sheet and cash flow plan come together, with capex as one line in it?	FP&A and consolidation teams
ERP investment modules	How are approved investments budgeted, booked and capitalised alongside the accounts?	Controllers, accounting, ERP and IT teams

Highlighted rows: the two categories Weissr Capex covers.

Capex software vs capital planning software: what is the difference?

Capex software and capital planning software differ in focus. Capex software is about control: are your requests, approvals, spend and actuals against the approved budget in one place, and can you trust the numbers? Capital planning software is about deciding where capital goes: across the whole portfolio, are you funding the investments that serve your strategy best? Purpose-built capex software, meaning software made for capex rather than an FP&A, ERP or project tool with a capex module added on, often covers both.

In the capex lifecycle, planning comes first. When organisations bring in software, most start with control, for a simple reason: a portfolio decision is only as good as the data underneath it. Control first. Then the harder question of where capital should go.

Weissr Capex is capex software for capital-intensive industries that covers long-term capex strategy, capital planning and capex control in one system. It comes as two modules. Capex Management handles capital planning, approvals and control, with a Capital Budgeting add-on for the approved budget. Capex Strategy sets the long-term direction the plan has to deliver.

Capital planning software vs capital project management software

The main difference between capital planning software and capital project management software is when each one is used. Capital planning software works before approval, deciding which projects to fund. Capital project management software works after approval, delivering one project on the ground: the schedule, the contractors, the contracts, the change orders, the earned value. Its users are project controls teams and engineers on site.

Capex software bridges the two. It runs each investment from request and approval through spend and close-out, and follows its money across the whole portfolio, alongside every other investment competing for the same capital.

Groups with large capital projects usually need both kinds of software, and the two should share data.

On the project side, Weissr Capex handles the financials of every project: budget, commitments, actuals and forecast. Scheduling, contractors and site work stay in your project management tools, and Weissr Capex connects to them and to your ERP. Finance keeps one view of what each investment costs against what was approved.

Evaluation checklist

What to look for in capital planning software: ten criteria

When you evaluate capital planning software, these are the ten criteria we recommend checking first. Each comes with a question worth putting to any vendor, including Weissr.

Criteria 1 to 3

Capex control: do you know where your capex stands?

The first three criteria test whether a system gives you control over the capital you have already committed: every request, approval and payment in one place, with numbers you can trust.

Structured investment requests

Everything downstream depends on how requests come in. If every site uses its own template, your controller spends the first weeks of each cycle rewriting business cases into one format before anyone can compare anything. And the request that wins is often simply the best-written one.

Ask the vendor

Can we standardise requests across all business units, or will every team keep submitting its own way?

In Weissr Capex, every request comes in through a configured form, with the right approval route and business case model applied automatically.

Capex approval workflow and governance

On paper, a capex approval system looks simple. A request goes up, someone signs, the money is released. In practice, a €50,000 pump replacement and a new paper machine should not travel the same road.

And requests change. The cost estimate grows by 20 percent after the board has already said yes. Who notices? In many workflow tools, only a controller who happens to catch it.

Ask the vendor

What happens to our approvals when the amount or scope of a request changes after the decision?

In Weissr Capex, the route follows the request: when the amount or scope changes, it moves to the right approval route automatically, and every decision lands in the audit trail.

Financial control: budgeted, committed, actual and forecast

Many capex reports tell you what has been spent against budget. By the time you see that number, it is usually too late to act on it.

Real control means keeping four numbers apart: what was budgeted, what is already committed through purchase orders, what has actually been spent, and what is forecast to land. Timing matters just as much. A project can finish exactly on budget and still put a large payment in the wrong quarter. And finance needs the same view for the whole portfolio: how much is committed across all sites right now?

Ask the vendor

Can we see commitments and cash timing as they happen, for each project and across the whole portfolio?

Weissr Capex imports spend, cash and commitments from your ERP for every expenditure line, keeps the forecast running from the current period and rolls everything up into one portfolio view.

Criteria 4 to 7

Capital allocation: are you funding the right investments?

The next four criteria test whether a system helps you decide where capital goes. This is the harder question. Every capex project looks profitable on paper. That is the problem. Every business unit can justify its own request, and "is this a good investment?" turns out to be the wrong question. The real one is whether this is the best use of the capital you have. That is where capital allocation starts.

Capital budgeting

At group level, a capital budget is where two numbers meet. Leadership sets the envelope from the top. Sites and business units bring their demand from the bottom. The gap between them gets closed somehow, often in a spreadsheet over several rounds of email, and afterwards it is hard to say who cut what, and why. Capital budgeting software closes that gap and keeps a record of every decision along the way.

Ask the vendor

Can we set and approve budgets at group, division and business unit level, and reconcile top-down targets with bottom-up demand?

In Weissr Capex, the Capital Budgeting add-on reconciles top-down targets with bottom-up demand at every level, and every transfer between budgets needs approval.

Consistent evaluation and prioritisation

Prioritisation gets political when requests are judged on different terms. One site reports IRR, another payback, a third brings a strategic argument with no number attached. Comparing them is like comparing prices in three currencies without an exchange rate.

Ask the vendor

Can we compare investments from different business units on the same criteria, beyond their individual ROI?

Weissr Capex scores every capex request on the same criteria: the strategic objective it serves, the risk of not doing it and its expected return. NPV, IRR and discounted payback are calculated the same way for every request.

Long-term capex strategy and portfolio optimisation

Even a consistent ranking of projects can miss the biggest decision. If you run several sites, your real options are rarely single projects. They are whole-business moves: expand one site and close another, upgrade technology everywhere, or carry on as today. And because a mill, a mine or a plant runs for decades, those moves have to be judged over the long term. The best portfolio is rarely the sum of individually approved projects.

Ask the vendor

Does the platform show us the best possible portfolio for the whole group over the long term, and does the strategy we approve then govern budgets and approvals?

Weissr's Capex Strategy models the whole business, its sites, assets and constraints, and simulates thousands of investment paths to find the combination and timing that creates the most long-term value. The strategy leadership chooses becomes the yardstick for every request.

Asset investment planning

Capex budgets have a way of drifting away from the assets they are supposed to keep running. A portfolio can look balanced for years while the replacement need of an ageing asset base quietly builds up. Then a breakdown turns a planned investment into an emergency one.

Ask the vendor

Is every investment linked to a physical asset, and can we compare the budget with what our asset base actually needs?

In Weissr Capex, every investment is linked to exactly one asset and actual spend updates the asset base, so predicted replacement needs can be set against the capital budget at every level.

Criteria 8 to 10

Control and allocation: the foundation underneath

The last three criteria apply to both tasks: whether control and strategy live in one system, whether that system fits into your IT landscape, and whether it works for a whole group and for your finance team.

Control and strategy in one system

Many groups end up with two tools: one for approvals and spend, another for strategy and portfolio planning, with a spreadsheet export in between. By the time the strategy team works with the numbers, the projects have moved on. And what a finished project actually cost and delivered rarely makes it back into the next round of planning. It sits in a post-completion report in someone's folder.

The most expensive capex system is often the one you outgrow.

Ask the vendor

Can a system we buy for control today grow into strategy later, or will we have to replace it, and migrate our data, when we are ready?

In Weissr Capex, strategy, budgeting and day-to-day capex management share one system and one set of data, and results from finished projects feed the next planning cycle.

Integration and reporting

Your capex system sits between the ERP, the asset register and your reporting tools. Every missing connection becomes a manual export someone has to run each month.

Ask the vendor

Does the platform connect in both directions to the ERP and asset systems we already run, and can we report from it in the BI tools we already use?

Weissr Capex connects in both directions to SAP, Oracle, IFS and other ERPs and to your asset management systems, and feeds Power BI, Tableau or Qlik with the same data.

Group-wide scale, security and ease of use

A system for a whole group has to work in every country and pass your IT security review. Every figure has to consolidate correctly across currencies, and access has to run through your identity provider. And a system that only consultants can configure will cost more every year than it did on day one.

Ask the vendor

Does the platform scale across all our sites, currencies and entities, and can we maintain it ourselves, or will we depend on the vendor for every change?

Weissr Capex consolidates figures across currencies, supports single sign-on, is ISO 27001 certified and lets finance teams configure it themselves. Implementation takes one to four months.

Where Weissr Capex fits in

Weissr Capex covers long-term capex strategy, capital planning and capex control, and all ten criteria above. It is built for capital-intensive groups in industries such as pulp, paper and forest products, metals and mining, chemicals, energy and manufacturing. Because control and planning run in one system on the same data, an organisation can start with Capex Management for control and add Capex Strategy for long-term strategy later, without changing tools or moving data.

Weissr Capex modules: Capex Management as the foundation, Capital Budgeting as a module within it, and Capex Strategy for optimisation — From the Capex Software Buyer's Guide: two modules on one connected data model.

Key takeaways

Online lists of the best capital planning software put capex software next to construction planning, facility management and FP&A software, each built for a different purpose. Before you compare vendors, decide what you need the software to do.
Purpose-built capex software, made for capex rather than added on to an FP&A, ERP or project tool, often covers both capex control and capital planning.
When organisations bring in capex software, most start with control, because a portfolio decision is only as good as the data underneath it. But control covers only part of the value. The harder question is whether capital goes to the investments that serve the strategy best.
Ten criteria show whether a system handles both capex control and capital planning well. Each comes with a question worth asking any vendor.

Capital planning software

Frequently askedquestions.

What is capital planning software?

Capital planning software helps an organisation decide which capital investments to fund, in what order and within what budget, usually over several years. It sits between long-term capital strategy and the approval of individual projects, and ends in an approved capital plan. Vendors also sell it as capital planning and budgeting software. It gathers proposed investments, evaluates them on consistent criteria, tests the portfolio against the available envelope and produces an approved capital plan. In Weissr Capex, capital planning is part of Capex Management, with the Capital Budgeting add-on for the budget and Capex Strategy setting the long-term direction, so the approved plan is the same record that projects are later approved and tracked against.

What is the difference between capital planning software and capital project management software?

Capital planning software works before approval and decides which investments to fund. Capital project management software works after approval and runs the execution of a single project: schedule, contractors, contracts, change orders and earned value. Capex software connects the two by following each investment's money from request to close-out. In Weissr Capex, the approved project is exported to the ERP and actuals and commitments flow back, while execution stays in the project management tool.

What is capex software?

Capex software, also called capital expenditure software, manages capital expenditure from request to close-out: structured investment requests, approval workflows, capital budgets, tracking of budgeted, committed and actual amounts, forecasting and post-completion review. Gartner groups these tools under capital investment management software. Weissr Capex is capex management software for capital-intensive industries, and it also covers capital planning and long-term capex strategy in one system.

Is capital planning software the same as FP&A software?

They overlap only at the edges. FP&A software plans the whole financial picture: P&L, balance sheet, cash flow and headcount. Capital planning software works at the level of individual investments and the portfolio they form, with their business cases, approvals and links to assets. Many groups use both. The FP&A platform sets how much capital the company can afford to spend, and the capital planning software decides where it goes.

What questions should you ask a capex software vendor?

Start with the practical ones. Can we standardise requests across business units? Can we see commitments, spend and forecast in real time? Can we configure approval workflows without custom development? Does every decision have an auditable trail? Can we plan budgets top-down and bottom-up across group, division and business unit? Does the platform integrate with our ERP and asset systems in both directions? Can a system we buy for control grow into strategy later? Weissr's Capex Software Buyer's Guide lists 25 such questions, including the ones worth asking Weissr.

Can capital planning be run in Excel?

Yes, and most organisations start there. Excel works while one person owns the file and the portfolio is small. It starts to break when requests come from many sites, approvals run over email and actuals are copied in from the ERP, because version control, audit trail and consolidation then depend on individual discipline. That is usually the moment organisations move to purpose-built capex software.
