For a lot of companies, October is when next year’s numbers start to harden. Department heads submit requests, finance pushes back, and by December the software line is mostly locked. Whatever didn’t make it into the plan becomes a mid-year conversation nobody wants to have.
The problem usually isn’t the big projects. Those get discussed, scoped, and argued over. The problem is everything around them: the costs that are real but quiet, so they never make it onto the spreadsheet.
Here’s what we see left out most often.
Renewals You Haven’t Looked at in a Year
Most software spend isn’t new spend. It’s subscriptions, licenses, and support contracts that renew on their own. Because they renew automatically, they tend to get copied forward from last year’s budget without anyone checking the actual terms.
That’s where surprises come from. Seat counts creep up as people join and nobody removes old accounts. Vendors change pricing tiers or move features you rely on into a more expensive plan. Multi-year deals signed at a discount come up for renewal at list price.
Before the budget locks, pull a list of every renewal that lands in 2027, with the date, the current cost, and who owns it. You’ll almost always find a few tools nobody uses anymore and a couple that are about to cost more than you think.
Cloud Commitments and Usage Growth
Cloud spend is hard to budget because it moves. If your product or traffic is growing, your bill grows with it, and last year’s number won’t hold.
Two things are worth planning for explicitly. First, usage growth: if you expect more customers, more data, or a new feature that does heavy processing, estimate what that does to compute and storage, not just headcount. Second, commitments: reserved capacity and savings plans can lower costs, but they lock you in. Know when your current commitments expire and whether you’re planning to renew, resize, or let them lapse.
We wrote more about this in how to catch cloud cost creep before the bill does. The short version for budgeting: use real usage trends, not last year’s total plus a guess.
Maintenance on Things You Already Shipped
This is the one that gets cut first and causes the most pain later.
Every app, site, and integration you launched needs ongoing work after launch. Dependencies need updates. Security patches come out. Third-party APIs change or get deprecated. Mobile apps need to be rebuilt for new OS versions and app store requirements. None of that is optional, and none of it shows up as a “project” in planning meetings.
When maintenance isn’t budgeted, it either doesn’t happen (and the system slowly gets riskier) or it happens by pulling people off planned work (and the roadmap slips). Either way, you pay for it.
A practical approach: for every system that’s in production, set aside a recurring maintenance allocation, separate from new feature work. The exact amount depends on how complex the system is and how many outside services it touches, but the line item should exist.
Knowledge That Lives in One Person’s Head
Some of your most important systems are probably understood by one person. Maybe it’s a long-time developer, an outside contractor, or the person who set up your cloud account years ago.
That’s a budget risk, even if it doesn’t look like one. If that person leaves, gets busy, or raises their rate, you’ll be paying someone new to learn the system from scratch, usually under pressure. We covered this in detail in what happens when the one developer who knows the system leaves.
The budget fix is cheaper than the emergency: fund some documentation and handoff time now, while the person who knows the system is still around to explain it.
Security and Compliance Work
Security work tends to show up mid-year as a reaction to something: a customer questionnaire, an audit request, an insurance renewal that asks new questions, or an incident.
If you sell to larger customers or work in a regulated space, you can usually predict some of this. Plan for periodic access reviews, dependency and vulnerability scanning, backup and recovery testing, and the time it takes to answer security reviews from customers. Even a modest allocation beats scrambling when a deal is waiting on it.
A Buffer for What You Can’t Predict
Something will come up. A vendor will sunset a product you depend on. A key integration will break. An opportunity will show up that needs quick development work.
Plenty of budgets have no slack for this, which means every surprise turns into a fight over what to cut. A modest, explicitly labeled contingency line is easier to defend in December than an emergency request in June.
How to Use This Before the Budget Locks
You don’t need a full audit. A few hours with the right people is usually enough:
- List every renewal landing in 2027, with dates and owners.
- Pull 12 months of cloud usage and estimate growth based on what you actually plan to ship.
- Name every production system and give each one a maintenance line.
- Identify the systems only one person understands and fund handoff time.
- Add security, compliance, and contingency as their own lines instead of hoping they fit somewhere else.
This isn’t accounting or tax advice. It’s the technical side of the plan, the part that tends to get underestimated because the people closest to it aren’t always in the budget meeting.
The Bottom Line
The software budget that causes trouble isn’t usually the one with the wrong big project in it. It’s the one that left out renewals, maintenance, and the quiet risks around systems you already rely on. Getting those on paper now is a lot easier than defending them in the middle of next year.
