Too Many Apps? How to Rationalise Your Software Portfolio

What is application portfolio rationalisation?

It is the structured review of all the software your business uses, with the aim of keeping what is valuable and removing what is redundant, risky or underused. The word portfolio signals that you treat applications as a managed collection rather than isolated purchases made by different teams at different times.

In many growing businesses, departments buy tools independently. Sales adopts one CRM-like app, marketing another, operations builds a spreadsheet system. Over time you pay for overlapping features, carry multiple logins and struggle to say which data is correct. Rationalisation brings order without stopping teams from getting their work done.

How do you find every application you actually use?

Start with finance records: card statements, subscription invoices and vendor payments reveal many tools. Then ask each department, review single sign-on and email domain sign-ups, and check IT asset lists. Do not forget spreadsheets, Google Sheets, personal accounts and WhatsApp-based processes, since business-critical logic often hides there.

For each application record the owner, purpose, users, data held, cost, renewal date, vendor, integrations and support status. This inventory is useful beyond rationalisation: it improves security reviews, budgeting and incident response. Keep it in a shared register that is updated when tools are added.

• Owner and business purpose.
• Number of active users and how often they log in.
• Annual cost and renewal or notice dates.
• Data stored and integrations with other tools.
• Vendor support status and technical condition.

How do you decide what to keep, merge or retire?

Score each application on business value, functional overlap with other tools, security and compliance risk, cost, user satisfaction and technical health. Simple one-to-five scores are enough. Two tools doing the same job are candidates for merging; unused or unsupported tools are candidates for retirement.

Apply a decision label: keep as is, invest and improve, merge into another system, replace with a better option, or retire. Consult users before deciding, because a tool that looks unused may support a quarterly or year-end process. Be wary of retiring something simply because it is old.

What does retiring an application involve?

Retirement is more than cancelling a subscription. You must decide what data to migrate, what to archive for legal or audit reasons, how to export it and who needs access afterwards. Check retention requirements with your accountant or adviser, and keep an archive in a readable format.

Plan user communication and training, set a cutover date and run the old and new systems in parallel when the risk is high. Remove integrations and credentials, and confirm that the vendor has deleted or returned your data in line with the contract.

• Export and verify the data you need.
• Archive records required for audit or legal reasons.
• Update integrations and automations that depended on the tool.
• Train affected users and announce the date.
• Close accounts, revoke access and confirm data deletion.

What are the common pitfalls?

The biggest pitfall is cutting purely on cost. A cheap tool that stitches two critical processes together may be more valuable than an expensive one nobody needs. Another is neglecting change management; if users are not consulted they will find workarounds and shadow tools reappear.

Avoid trying to fix everything at once. Begin with obvious duplicates and unsupported systems, show visible savings and reduced risk, then tackle the harder consolidations. Keep leadership informed so decisions have authority.

How do you stop sprawl coming back?

Introduce a lightweight approval step for new tools: who needs it, what does it overlap with, where will data live, who owns it. Keep the register current and review it annually, ideally before budget season, when renewal decisions are easy to influence.

Where internal capacity is limited, specialist application management support can maintain the register, monitor renewals and run reviews on your behalf. Whoever does it, the principle is the same: every application should have a reason, an owner and a review date.

Step by step

1. Build the inventory. Collect tools from finance records, department interviews and access logs.
2. Capture key facts. Record owner, users, cost, data, integrations and renewal dates for each.
3. Score each application. Rate value, overlap, risk, cost and health on a simple scale.
4. Decide and plan. Label each as keep, improve, merge, replace or retire, and plan migration.
5. Retire carefully. Migrate data, train users, switch over and close accounts.
6. Review yearly. Repeat the review and require approval for new tools.

Frequently asked questions

How long does rationalisation take?

A small business can complete a first pass in a few weeks. Larger portfolios need phased work, with quick wins first.

Should we involve end users?

Yes. Users know which features matter and which workarounds exist, and their involvement reduces resistance.

What about spreadsheets?

Include business-critical spreadsheets in the inventory. Some deserve to become proper applications because they carry important logic and data.

Do we save money immediately?

Often there are savings from duplicate subscriptions, but the greater benefit is lower risk and cleaner data. Results vary by situation.
