SaaS Subscription Management: How to Stop Overspending on Software

Most businesses vastly underestimate how much they spend on software. Individual tools get approved ad hoc. Free trials quietly convert to paid plans. Seat counts grow with headcount but rarely shrink when people leave. And because each payment is a relatively small amount on its own, the aggregate rarely gets proper scrutiny.

The result is SaaS sprawl — and for many SMEs, it represents thousands of pounds of unnecessary expenditure every year. This guide explains how the problem develops, how to audit what you're actually spending, and how to put a process in place that keeps it under control.

The Scale of the Problem

Research consistently shows that the average SME uses 40 to 50 SaaS tools. Of those, around 30% are either unused, duplicated across teams, or so lightly used that they could be consolidated or cancelled without any meaningful impact on operations.

The issue is rarely that any single tool is obviously wasteful. The problem is the accumulation — a project management tool here, a video conferencing add-on there, a specialist reporting tool that one team uses once a month — each individually defensible, collectively expensive and largely unaudited.

Why SaaS Costs Creep

Decentralised Approvals

In most small businesses, individual team members or department heads can approve software purchases up to a certain amount without central IT or finance sign-off. This is often sensible — it enables teams to move quickly. But it also means that no single person has visibility of all the tools being purchased across the organisation, and there is no check for duplication.

Free Trials That Convert Automatically

SaaS vendors have become sophisticated at converting free trials into paid subscriptions. The trial ends, payment starts, and if the person who signed up has moved on or forgotten about the tool, the charges can continue for months before anyone notices. This is particularly common with tools that were evaluated but never fully adopted.

Per-Seat Pricing That Grows but Never Shrinks

Per-seat SaaS pricing scales automatically when you add users — typically because adding a user triggers an immediate charge or an adjustment to the next invoice. But reducing seats when people leave, change roles, or stop using a tool requires active intervention that rarely happens without a process in place. The result is that you pay for licences that are no longer in use.

Annual Renewals That Pass Unnoticed

Annual SaaS subscriptions are particularly prone to being forgotten. The invoice arrives once a year, often paid automatically by a credit card on file, with no one actively reviewing whether the tool is still needed or whether a better deal is available elsewhere.

How to Audit Your SaaS Subscriptions

A SaaS audit does not need to be a large project. The goal is simply to get a complete picture of what you're paying for. Here is how to approach it:

Check Bank Statements and Credit Card Records

The most reliable source of truth is the money leaving your accounts. Go through the last 13 months of business bank statements and credit card statements, looking for recurring payments. Thirteen months (rather than twelve) ensures you catch any annual subscriptions that renew on different months. Note each vendor name, amount, and frequency.

Ask Department Heads

Finance records show what is being paid, but not always who authorised it or whether it is still used. Ask each department head to list the software tools their team relies on, what they use them for, and an estimate of actual usage. Compare this against your payment records to identify tools that are being paid for but not used by any team.

Review IT Purchasing Records

If you have a dedicated IT function, check their purchasing records for any software licences, cloud services, or infrastructure tools that may not appear on the main business accounts. Security tools, monitoring services, and developer platforms are commonly found here.

Check for Duplicate Tools

Once you have a complete list, look for duplication: two project management tools, two video conferencing platforms, two design tools. Duplication is extremely common and is usually the result of different teams independently choosing tools that serve the same purpose.

What to Track for Each Tool

For every SaaS subscription, record the following:

• Tool name and vendor
• Renewal date — the date the next payment will be taken or the next term begins
• Annual cost — normalised to an annual figure for easy comparison
• Subscription owner — the person responsible for the decision to renew or cancel
• Number of licensed seats and number of active users
• Last active use — when was the tool last meaningfully used?
• Alternatives — is this functionality covered by another tool you already have?

This information tells you, for each tool, whether it is actively used, whether it is duplicated, and whether the number of seats matches actual usage. These three questions answer whether the subscription should be continued as-is, reduced, consolidated, or cancelled.

Rationalisation: How to Cut the Waste

Cancel Unused Subscriptions Immediately

Any tool that no one is actively using is a candidate for immediate cancellation. Check whether there is a notice period requirement and serve notice before the next renewal date. For monthly rolling subscriptions, this is straightforward — a month's notice is usually sufficient. For annual contracts, note the renewal date and set a reminder to cancel well in advance.

Consolidate Duplicate Tools

Where two teams are using different tools for the same purpose, consolidation usually generates savings and reduces complexity. Choose one tool, migrate the users, and cancel the other. The consolidation decision may require some stakeholder management — people become attached to their tools — but the financial and operational case is usually clear.

Right-Size Seat Counts

For per-seat licences, reduce your seat count to match actual active users. Many vendors will allow you to reduce seats at renewal rather than mid-term — so note the renewal date and ensure you review the seat count before it arrives. Some vendors will accommodate mid-term reductions where there is a clear business case; it is always worth asking.

Negotiate at Renewal

Renewal time is your window of maximum leverage. Most SaaS vendors offer discounts for longer commitments, larger seat counts, or simply when faced with a credible threat of cancellation. If you have researched alternatives and can demonstrate that a competitor offers better pricing, say so. Even a 10–15% reduction on a significant annual licence adds up meaningfully over time.

Prevention Going Forward

Maintain a Central SaaS Register

The audit gives you a starting point; the register keeps it current. Maintain a central record (a dedicated tool, a spreadsheet, or a contract management platform) of all active SaaS subscriptions, updated whenever a new tool is added or an existing one is cancelled or changed.

Set Renewal Alerts

For every annual subscription, set a reminder at least 60 days before the renewal date — enough time to review usage, check alternatives, and serve notice if needed. For monthly subscriptions, an annual review date is sufficient. The MyRenewals platform is designed specifically for this: add each subscription once, and it sends automatic alerts before every renewal deadline.

Require Central Approval for New Tools

Establish a simple approval process for new SaaS purchases above a minimal threshold. The goal is not to slow teams down, but to ensure that someone checks for duplication before a new subscription is added, and that the renewal date and owner are recorded at the point of purchase. A short approval form that takes two minutes to complete is enough to prevent the problem from recurring.
