It is the first Monday of the month. You are reconciling the business card and spot a $39 charge you can't place.
You search your inbox and find the receipt. It is a scheduling tool someone trialed last spring, and nobody has logged in since June.
Then you keep scrolling: two email platforms, three design apps, a social scheduler and a survey tool you forgot you bought. The fix is not a better tool. It is a 90-minute audit, run twice a year.
Tools are easy to buy, and nobody owns the cancellation. A free trial turns into a monthly charge, and the person who wanted it moves on to the next problem.
Bigger companies have the same habit with bigger bills. Zylo's 2026 SaaS Management Index puts the average organization's software portfolio at 305 applications. Spending on AI-native apps jumped 108% in a single year.
Budgets are not keeping pace. In Gartner's 2026 CMO Spend Survey, 56% of CMOs said their marketing team lacks the budget to deliver its 2026 strategy. Every unused subscription widens that gap.
A small business has no procurement team to catch this, so the audit below does that job.
STACK stands for Surface, Tie, Assess, Cut and Keep. Do the steps in order, because each one feeds the next. Block 90 minutes and open a blank spreadsheet.
1. Surface every subscription. Pull 12 months of card and bank statements, plus the receipts in your inbox. List every recurring charge, including annual plans and add-ons that renew quietly.
2. Tie each tool to one job. Write the single job each tool does in plain words, such as "sends the monthly newsletter." Flag any tool without a job, and any two tools that share one.
3. Assess real usage. Check the last login date, seats paid against seats used, and which features anyone touches. A tool used once a quarter is not part of your workflow.
4. Cut, consolidate or commit. Give every tool one verdict, using the table below. Cancel the cuts today, not at the next renewal.
5. Keep an owner and a renewal calendar. Each surviving tool gets one named owner and a renewal date in a shared calendar. Thirty days before renewal, the owner decides whether it still earns its fee.
Judge every tool on usage and overlap, not on features. A tool with brilliant features that nobody uses is still dead weight.
| Verdict | Signal | What to do |
|---|---|---|
| Cut | No login in 60 days, or nobody can name its job | Export the data, then cancel today |
| Consolidate | Two tools do the same job | Keep the one the team uses daily, migrate, then cancel the other |
| Downgrade | Paid seats or plan features sit unused | Drop to the seats and plan you actually use |
| Commit | Used weekly and tied to leads or sales | Keep it, train the team and use more of what you pay for |
Here is what a finished audit sheet looks like. The tools and figures below are sample data, not a real business.
| Tool | Job | Monthly cost | Last login | Seats paid / used | Verdict |
|---|---|---|---|---|---|
| Email platform A | Monthly newsletter | $59 | Today | 3 / 3 | Commit |
| Email platform B | Monthly newsletter | $45 | February | 2 / 0 | Consolidate |
| Scheduler A | Schedules social posts | $39 | June | 1 / 0 | Cut |
| Design app | Social graphics | $120 | Yesterday | 5 / 3 | Downgrade |
| Survey tool | None named | $25 | Never | 1 / 0 | Cut |
Consolidation is where most of the savings hide. Many all-in-one platforms now bundle email, forms, scheduling and landing pages. One tool used well beats three tools used halfway.
Be careful with tools that hold your contacts or your sending reputation. Export everything before you cancel. If you switch email platforms, re-check your sender setup with our email deliverability checklist.
Fewer than most pay for. A typical small business needs one tool for each of five jobs, and nothing that duplicates them.
Everything else should earn its place against a specific problem. Our guide to building a content calendar that survives week three shows how to plan content without adding software.
AI subscriptions pile up fastest, because several general assistants do overlapping jobs. Two people on one small team can easily end up paying for two different assistants.
Apply the same STACK rules. Pick one general AI assistant for the team, and pay for a specialist only when it clearly beats that assistant at a named job. We covered which tasks to hand to AI in how AI copywriting tools are reshaping content workflows.
Run the full STACK audit twice a year, plus a quick check whenever someone asks for a new tool. Six months is long enough for trials to become habits and short enough to catch them.
The quick check is one question: which tool we already pay for does this job? If the answer is a tool nobody uses, fix adoption before you buy anything new.
A lean stack also makes the next wave of tools easier to adopt. In Gartner's 2025 survey of 413 martech leaders, half said they lack the technical and data stack readiness to deploy AI agents.
Plan on about 90 minutes for a business with fewer than 20 subscriptions. Most of that time goes into finding every charge. Later audits are faster because the list already exists.
Export your data first, then cancel. If the tool is a duplicate, you already have the replacement. If it does a unique job, migrate to the new tool before the renewal date.
For most small teams, yes. One login, one contact list and one bill beat a slightly better feature in a separate app. Choose a separate tool only when its job is central to how you sell.
One person owns the master list and the renewal calendar, usually the owner or office manager. Each tool also gets a day-to-day owner who decides whether it renews.
Ask each person to name the tool's job and the last time they used it. Usage data settles most arguments quickly. Keep what passes and cancel the rest.
Same card statement, six months later. Every charge on it has a name, a job and an owner in your spreadsheet.
The forgotten scheduler is gone, and so is the second email platform. The renewal reminder for your design app arrived 30 days early, so you dropped two unused seats before paying for another year.
Your next step takes ten minutes: download the last 12 months of card statements and highlight every recurring charge. That list is step one of your first STACK audit.
