Scan Invoices and Track Expenses Right Inside WhatsApp
Quick answer: Yes — you can track expenses on WhatsApp by sending a photo or PDF of any receipt or invoice. Agent Sonic reads the vendor, amount, and date, then logs the row to your Google Sheet. Later you just ask, "How much did I spend on suppliers this month?"

Your receipts are dying in your camera roll — here's where they should go instead. You already photograph every receipt. The problem? That photo dies in your camera roll and the number never reaches your books. So send that photo to Sonic in WhatsApp instead. Snap a coffee receipt, forward a PDF invoice — one message, "Log this receipt," and that's the whole workflow. Sonic doesn't just store the image — it reads it, pulling the vendor, amount, and date. If something's blurry, it asks: was that 240 or 248? Then it lands in your Google Sheet — not some black box. Your sheet, your columns, your data. Your accountant can open it; you can export it at tax time. And the point of logging isn't the log — it's the answers. Just ask, "How much did I spend on suppliers this month?" and Sonic reads the sheet and tells you. This is built for people who hate bookkeeping. You hand over the receipt; Sonic does the typing, the categorizing, and the math. You stay in the app you already check fifty times a day. Snap it, forward it, forget it. Sonic does the books.

Snap it, forward it, forget it
You already photograph receipts. The problem is what happens next — the photo dies in your camera roll and the number never makes it into your books.
Send that photo to Agent Sonic in WhatsApp instead. Snap a coffee receipt, forward a supplier's PDF invoice, screenshot a card charge — whatever you've got. Sonic reads it.
One message: "Log this receipt." That's the whole workflow. No app to open, no form to fill, no folder to organize.
What Sonic actually pulls from a receipt
Sonic analyzes the document — photo or PDF — and extracts the fields that matter for bookkeeping. It doesn't just store the image; it reads it.
If something's blurry or missing, it asks. "I can't read the total on this one — was it 240 or 248?" You answer in one line and it's done.
| Field | Example from a receipt | Why it matters |
|---|---|---|
| Vendor | Mario's Print Shop | Groups spend by who you pay |
| Amount | $148.00 | The number for your books |
| Date | May 12, 2026 | Lands it in the right month |
| Category | Office supplies | Answers 'what did I spend on?' |
| Currency | USD | Keeps multi-currency clean |
It lands in your Google Sheet, not a black box
Connect your Google Sheet once and Sonic writes each expense as a new row — vendor, amount, date, category. It's your sheet, your columns, your data. There's no separate app or dashboard to log into.
Want it somewhere specific? Say "Add this to my 2026 Expenses tab" and that's where it goes.
Because it's a normal spreadsheet, your accountant can open it, you can filter it, and you can export it at tax time without exporting anything from anywhere.
Ask your spending questions in plain English
The point of logging isn't the log — it's the answers. Once your expenses live in the sheet, you just ask.
"How much did I spend on suppliers this month?" "Total up my expenses for May." "What did I pay Mario's Print Shop this quarter?" Sonic reads the sheet and tells you.
No pivot tables, no formulas. You ask the question you'd ask a bookkeeper, and you get the number back in WhatsApp.
Built for people who hate bookkeeping
If you're a freelancer or run a small shop, you don't have an accounts team — you have a shoebox of receipts and a vague sense of dread every quarter.
Delegating the boring part is the whole idea. You hand Sonic the receipt; Sonic does the typing, the categorizing, and the math. You stay in the one app you already check fifty times a day.
Catch receipts the moment they happen
Bought lunch with a client? Forward the card text. Paid a supplier? Snap the invoice before it goes in a drawer. Logging at the moment of spend means nothing gets lost.
And because Sonic remembers, you can come back later and ask, "Did I ever log that hardware store receipt from last week?" It checks and tells you.
Frequently asked questions
Can Agent Sonic read a photo of a crumpled paper receipt?
Usually, yes. Sonic analyzes the image and pulls the vendor, amount, and date. If a field is too blurry to read, it asks you to confirm that one value instead of guessing — for example, "Was the total 240 or 248?"
Does it work with PDF invoices, not just photos?
Yes. Forward a PDF invoice the same way you'd send a photo. Sonic reads PDFs, contracts, invoices, and spreadsheets, so a supplier's emailed invoice works fine — just share it into the chat and say "Log this."
Where do my expenses get stored?
In your own Google Sheet. Sonic adds one row per receipt with the vendor, amount, date, and category. There's no separate Agent Sonic app or dashboard — it's your spreadsheet, which you and your accountant can open any time.
Can I ask for totals later?
Yes. Once expenses are in your sheet, ask things like "How much did I spend on suppliers this month?" or "Total up my expenses for May." Sonic reads the sheet and replies with the number in WhatsApp.
Do I need to install anything?
No. Agent Sonic lives entirely inside WhatsApp — no app to download and no dashboard to learn. You connect your Google Sheet once, then just send receipts to the chat.
