Log Expenses to Google Sheets Straight From WhatsApp

The problem isn't the spreadsheet. It's the updating.

Most people who track expenses already have a sheet. A clean one, with columns and formulas and a monthly tab. The trouble is remembering to open it.

So the receipts pile up. You tell yourself you'll catch up on Sunday. By Sunday you've forgotten half of them, and the sheet is a week behind reality.

The fix isn't a better spreadsheet. It's not having to open it at all. You text the expense the moment it happens, and the row appears where it belongs.

Just text the expense as it happens

Agent Sonic connects to your Google Sheets. When you pay for something, you send a message in plain language — the way you'd tell a friend.

"Add 240 shekels, lunch with client, to my expenses sheet." That's it. Sonic finds the sheet, drops in the date, the amount, and the note, and confirms it's done.

No app to open, no form to fill, no dashboard to log into. The expense gets recorded in the four seconds it takes to type one sentence.

It's not only expenses

Any sheet you keep can be fed the same way. If it's a row of data, Sonic can add it.

"Log this month's mileage — 320 kilometers." "Add a lead: Dana from Wave Studio, dana@wave.co, interested in the retainer." "Put down 6 hours on the Hadar project today."

Leads, billable hours, inventory counts, workout logs — if you've built a column for it, you can fill it from WhatsApp without breaking your stride.

Why texting beats opening the sheet

The whole point of a tracker is that it's complete. A sheet with gaps in it lies to you — it tells you you spent less than you did.

Logging in the moment closes the gaps. You're already holding your phone when you pay. One message later, it's recorded, and you never have to reconstruct the week from memory.

Your sheet, your structure

Sonic works with the sheet you already have — your columns, your tabs, your naming. You don't rebuild anything to fit a new tool.

Tell it which sheet to use the first time, and after that you can just say "my expenses sheet" or "the leads tab" and it knows where you mean. It remembers, so you don't repeat yourself.

And because Sonic keeps context, you can be casual: "Same as yesterday but 180" works, because it remembers yesterday.

A few honest notes

Sonic adds and reads rows in the sheets you connect — it works through Google's own integration, so you stay in control of access.

It lives entirely in WhatsApp. There's no separate app and no dashboard to learn. The chat you already use all day is the whole interface.

If a message is ambiguous — say the amount is missing — Sonic asks before writing, rather than guessing and leaving you with a wrong row to hunt down later.
