# How to Audit Your Software Subscriptions in One Hour

*How-to — 2026-09-27 — by Mahmoud Zalt*

A practical one-hour audit of your software subscriptions: where charges hide, four questions per tool, and what to do with the result.

**Short answer.** **Pull twelve months of charges, not one, then ask four questions about every line.** Twelve months catches annual renewals, which are where the forgotten money hides. The four questions are: who uses it, what breaks without it, when does it renew, and is it storing something or doing something. You will finish with three lists and a renewal calendar, and the whole thing takes about an hour.

Do this before you change anything. Not before you buy an AI tool, not before you negotiate with a vendor, not before you argue with your team about which app is essential. An audit is boring and it is the only step that makes every later decision cheap instead of contentious.

The reason most audits fail is scope. People open one month of statements, find nine familiar charges, feel reassured, and stop. The charge that matters is the 1,200 dollar annual renewal from eight months ago for a tool that is now used by nobody, and it will not appear in a one-month view.

This piece is the exercise itself, not the philosophy. At the end you will know exactly what you pay for, who touches it, and what would break without it. That inventory is what lets you decide sensibly whether an AI Employee on **Sistava** can take over any of it, and, just as importantly, which parts must stay exactly where they are.

- **4** Questions asked about every single line
- **3** Payment sources most teams forget to check
- **1 hr** Realistic time for a team under fifteen people

## Where do software charges actually hide?

In four places, and only one of them is your company card. The others are the app store account tied to a phone, a payment wallet used during a rush three years ago, a founder's personal card that was never switched over, and any subscription billed through a reseller or agency partner. Miss these and your audit undercounts by fifteen to thirty percent.

There is a fifth hiding place that catches nearly everyone: charges that changed name. Vendors get acquired and the line on your statement becomes an unfamiliar holding company. If you cannot identify a recurring charge from the description, search the amount in your email inbox. The receipt will be there.

## What four questions do you ask about each tool?

Ask who, what, when, and which. Who logged in last, and how recently. What breaks if it vanishes tonight with its data. When does it renew and for how much. Which kind is it: a tool that stores the authoritative version of something, or a tool that does work on top of something stored elsewhere. Four answers per line, nothing more.

The who question is the most productive and the least popular. Almost every per-seat tool has seats belonging to people who left, contractors who finished, and colleagues who tried it once. Open the admin panel, sort by last login, and you will usually find your first saving before you finish the audit.

The which question is the one that decides everything afterwards. A storing tool is a system of record and it stays, full stop. A doing tool is a candidate for consolidation. Keep the answers to one word each so the sheet stays readable, because a sheet nobody reads is the same as no audit at all.

## What does a finished audit look like?

Three lists and a calendar. List one is keep permanently, your systems of record. List two is cancel now, the seats and tools nobody has touched in thirty days. List three is consolidate, the doing tools that a single worker could absorb. The calendar holds every renewal date with its amount, which is what keeps the audit from decaying.

Elena runs a three-person bookkeeping practice in Manchester with a rotating set of contractors. She expected her audit to find about 400 dollars a month. She found 785, spread across sixteen charges, three payment sources, and one annual renewal she had genuinely forgotten existed.

| What Elena found | Amount | List | Why |
|---|---|---|---|
| Accounting platform and client portal | $310/mo | Keep | The legal record of every client's books |
| Document storage and e-signature | $88/mo | Keep | Signed originals, needed for audits |
| Practice management database | $120/mo | Keep | Client history and deadlines live here |
| Four contractor seats, no login in 90 days | $96/mo | Cancel now | Nobody using them, no argument to be had |
| Annual tax research subscription | $1,140/yr | Cancel now | Replaced by the platform's own updates last year |
| Client reminder and chasing tool | $59/mo | Consolidate | Sends emails on a schedule, stores nothing |
| Proposal and engagement letter builder | $45/mo | Consolidate | A template merge, drafted better from past letters |
| Monthly client report generator | $67/mo | Consolidate | Formats numbers that already live in the platform |

Elena cancelled the dead seats and the annual research subscription that same afternoon, which was 191 dollars a month once the annual charge is spread out. She left the three consolidate items running while she tested whether one AI Employee could handle client chasing, engagement letters, and monthly reports. Two of the three moved over cleanly. The report generator stayed, because two clients insisted on its exact layout.

## How do you keep the audit from going stale?

One person owns the software card, every new subscription must name the recurring job it removes, and the renewal calendar gets ten minutes once a quarter. That is the whole maintenance routine. Bills creep because nobody owns them, not because software is inherently expensive.

The renewal calendar deserves a note of its own. Most vendors send a renewal notice thirty days out, into an inbox that is already drowning. If the date is in a calendar you actually look at, each renewal becomes a decision. If it is not, every renewal is an automatic yes, forever.

### The one-hour audit, in order

1. **Gather twelve months from every payment source** — Company card, app store account, payment wallet, personal card, and any reseller invoice. Export to one sheet, one row per recurring charge.
2. **Name every unfamiliar charge** — Search the exact amount in your email inbox. Acquired vendors change their statement descriptor, and those are usually the oldest charges you have.
3. **Answer who, what, when, which** — One word per column. Last login, what breaks, renewal date and amount, storing or doing. Do not add extra columns, they slow the sheet to a halt.
4. **Split into keep, cancel now, and consolidate** — Cancel the dead list today, it is cleanup rather than a decision. Leave keep alone. Take consolidate into a real two-week test before touching it.
5. **Build the renewal calendar and hand it an owner** — Every date, every amount, one named person, ten minutes a quarter. This is what stops the bill from quietly rebuilding itself within a year.

## What should the audit not lead you to do?

It should not lead you to cancel a system of record because it turned out to be your biggest line. Your accounting platform, payment processor, client database, and document storage are supposed to be the expensive part. They hold the facts, carry the compliance duty, and cannot be reconstructed from a chat log.

It should also not lead you to cancel five things in one week. Each cancellation carries a small unknown, and five unknowns landing together makes it impossible to tell which one caused the problem. Two at a time, with a full billing cycle between rounds, is slower and finishes sooner.

## Comparison

| Dimension | Traditional | With Sista |
|---|---|---|
| History reviewed | One month of the company card | Twelve months across every payment source |
| Questions asked | Do we still need this, roughly | Who, what breaks, when it renews, storing or doing |
| First action | Debate the most contested tool | Cancel dead seats, which nobody defends |
| What happens next quarter | Charges drift back, nobody notices | Renewal calendar, one owner, ten minutes |
| Outcome | A spreadsheet nobody opens again | Three lists and a date for every renewal |

## Frequently asked questions

## FAQ

### How often should I audit my subscriptions?

A full audit once a year, and a ten-minute renewal calendar review each quarter. More often than that and it becomes a chore people skip. Less often and you lose a full year of an annual renewal nobody needed.

### What is the fastest saving an audit usually finds?

Idle seats. Open every per-seat tool, sort users by last login, and remove anyone dormant for thirty days. It takes twenty minutes, requires no new tools, and produces the one cut nobody argues about.

### Should I include tools my team pays for personally?

Yes, and expect surprises. Personal expensing is how duplicate tools appear, where three people each pay for a different version of the same thing. Bringing them into the list often reveals a cheaper shared plan.

### Can an AI Employee run the audit for me?

It can do most of the assembly work: pulling statement exports into one sheet, matching unfamiliar charges to receipts in your inbox, and building the renewal calendar. The judgement calls about what breaks without a tool are yours, because only you know what your customers and your accountant depend on.

### What if a tool is cheap but genuinely unused?

Cancel it. Cheap unused tools are worse than expensive ones because they never get reviewed. Five forgotten nineteen dollar subscriptions cost more per year than the tool everyone argues about, and none of them are doing anything.

### Do I need software to run a subscription audit?

No. A sheet with six columns beats a spend management platform for any team under about fifty people. Buying a subscription to track your subscriptions is a decision worth delaying until the manual version has genuinely become the bottleneck.
