# WhatsApp Bot > Log travel expenses from a WhatsApp chat. Send a photo, a PDF, a voice message, or just type the amount, and the expense lands in your trip. Source: https://spentrip.app/help/whatsapp ## What Is the WhatsApp Bot? The Spentrip bot lives in WhatsApp. Send it a photo of a receipt, a PDF, a voice message, or just type 18 EUR paella in Barcelona — the expense is created and filed into your trip. No switching apps, no waiting until the end of the day. It's the fastest way to capture an expense while you're actually out spending: you're already in WhatsApp, so the receipt goes in before it ends up crumpled in a pocket. Start a chat at [spentrip.app/whatsapp](/whatsapp/) — it opens WhatsApp on your phone, or shows a QR to scan if you're at a desktop. The bot's number is **+1 555-970-2123** if you'd rather add it by hand. To link an existing account, open **Settings → WhatsApp** in the app. ## Linking Your Account 1 #### Copy Your Code Open Settings → WhatsApp in the app. Your unique code is on screen — tap to copy it. 2 #### Open WhatsApp Tap Open WhatsApp to start a chat with the bot, or message the number by hand. 3 #### Send Your Code Paste the code as your first message to the bot. 4 #### Done The bot confirms the link. Start sending expenses right away. Already chatting with the bot but haven't linked yet? Send /login and it will ask for the code. ## What You Can Send Four ways to log an expense, all in the same chat: ### Plain Text Type the expense however you'd say it. The AI pulls out the amount, currency, and merchant. 18 EUR paella in Barcelona ### Receipt Photos Snap the receipt and send it. The same OCR that powers in-app scanning reads it. - JPG, PNG, WebP - Merchant, amount, and date extracted ### PDF Receipts Forward the PDF invoices that hotels and airlines email you straight into the chat. - PDF documents - Share directly from your mail app ### Voice Messages Hold the mic and say it out loud. Useful when your hands are full of luggage. Forty euros for the taxi from the airport ## Sending to the Right Trip Expenses go to your default trip unless you say otherwise. Three ways to steer them: - **Set a default** — send /trip to pick which trip new expenses land in - **Override per expense** — add #trip:Name to send just that one elsewhere, like 15 EUR pizza #trip:Rome2026 - **Tag as you go** — any other hashtag becomes a tag: 4 EUR coffee #business. Tags require a subscription ## Commands - **/help** — the full list, any time - **/stats** — spending breakdown for the trip - **/trip** — choose your default trip - **/signup** and **/login** — create an account, or connect one you already have - **/install** — a link to download the app - **/unlink** — disconnect your number from your account - **/stop** and **/resume** — opt out of marketing messages, or back in ## Managing the Connection Settings → WhatsApp shows the current state. Once linked, you'll find an **Open WhatsApp** button that jumps straight to the chat, the bot's number if you'd rather start the conversation yourself, and **Unlink WhatsApp Account** to disconnect. Unlinking asks for confirmation first, and you can relink later with a fresh code. ## Tips & Details ### You Can Start Before You Install Message the bot without a Spentrip account and it will still log your expenses. When you're ready, send /signup and everything you've already sent comes with you. ### Free Allowance The WhatsApp channel includes 10 free receipts. That allowance is counted separately from the app and from the Telegram bot. After that, a subscription keeps them flowing. ### Speaks Your Language The bot replies in English, German, Spanish, French, Italian, Polish, Portuguese, and Russian, following the language of your phone. ### Everything Syncs Expenses sent over WhatsApp are ordinary expenses. Edit them in the app, add them to reports, share them with trip members — nothing about them is second-class. ### One Number, One Account A phone number links to a single Spentrip account. To move it to a different account, unlink first, then send the new account's code. ## Related Articles [Receipt Scanning Scan paper receipts and PDFs with AI-powered OCR.](/help/receipt-scanning.md) [Email Forwarding Forward receipt emails and have them added automatically.](/help/email-forwarding.md) [Telegram Bot Log expenses from Telegram, including shared group chats.](/help/telegram.md)
