Subscription Expense Tracking: Spreadsheet vs App vs AI

You can track subscription expenses three ways: a spreadsheet you fill in yourself, a tracker app (manual or connected to your bank), or a tool that reads your bank statement. They differ most in whether they can find a subscription you've forgotten.

Approach 1: the spreadsheet

A Google Sheet or Excel file with columns for service, amount, billing date, category and a business or personal tag.

Strengths:

• Free, and fully under your control.
• Easy to share: email a CSV to your accountant.
• Formulas give monthly, annual and per-category totals.
• Works offline.

Weaknesses:

• It only holds the subscriptions you remember, so the forgotten ones never make it in.
• You update it by hand every time you sign up, cancel or see a price rise.
• It won't remind you before a renewal unless you build that yourself.

Best for:

People with a short list of subscriptions they can already name, who prefer not to use a third-party tool.

Approach 2: the tracker app

Tracker apps come in two kinds. Manual apps such as Subtrack, SubPolice and Revuno show totals and remind you before renewals, but you type in each subscription (SubPolice, on Android, also reads your notifications to spot renewals). Bank-connected apps find recurring payments from your transactions:

• Frollo and WeMoney link the accounts you choose through the Consumer Data Right (open banking) where your bank offers it, which gives them read-only access to your transactions without your banking password. For institutions outside open banking, both connect through a data partner that asks for your bank login.
• The Westpac app finds recurring payments on Westpac debit and credit cards and can cancel eligible subscriptions, for Westpac customers only.

US apps such as Rocket Money connect through Plaid, which doesn't support Australian banks, so they can't see an Australian account. The Rocket Money alternatives guide covers what to use instead.

Strengths:

• A mobile dashboard with monthly and yearly totals.
• Renewal reminders.
• Bank-connected apps find subscriptions automatically, and Frollo, WeMoney and the Westpac app are free.

Weaknesses:

• Manual apps share the spreadsheet's problem: they only track what you add.
• Bank-connected apps keep an ongoing connection to your accounts, and each sees only the accounts you link.
• Frollo and WeMoney are full budgeting apps, which is more than some people want for a subscription list.

Best for:

People who want live tracking and are happy to connect their banks (Frollo, WeMoney, or the Westpac app for Westpac cards), or people who know every subscription and want reminders (a manual app).

Approach 3: the statement scan

You upload a bank statement (PDF, CSV or Excel) and AI lists the recurring charges on it, usually in about a minute, with no bank login or connection.

SubTracker works this way. You upload a statement, review what it found, tag each subscription business or personal, and save the ones you want to track.

Strengths:

• Finds forgotten subscriptions.
• No bank login and no ongoing connection. The statement file is deleted when the scan finishes, and results are deleted after 24 hours unless you save them.
• Works with any Australian bank that exports a statement.
• Business or personal tags, with a CSV export of all saved subscriptions or only the business ones.

Weaknesses:

• It isn't live: you upload a fresh statement to check for new subscriptions.
• It sees only the statements you upload, so it misses a card or account you leave out.
• AI can miss a charge or misread one, so you review the results before saving.

Best for:

People who suspect they're paying for things they've forgotten, want an audit without connecting a bank, or need a business export for their accountant.

The comparison table

Which one should you use?

If you can name every subscription you pay for, a spreadsheet or manual app is enough. If you think some have slipped your mind, use something that reads your transactions: a bank-connected app if you're happy to link your accounts, or a statement scan if you'd rather not.

For a freelancer or small business, a statement scan each quarter plus a CSV export into your spreadsheet or accounting software catches new subscriptions and keeps your records in your own files.
