New Features
We spent an additional 21 hours adding the following features to the Totonos we built in 29 hours.
Inventory Management: Scan and Update from Your Phone
"Inventory is the one thing still stuck in Excel..." -- This fixes that.
It is as simple as three steps:
- Tap the "Scan" button on your phone
- Point the camera at the product barcode
- Adjust the quantity and you are done!
Supported barcodes: JAN codes (Japanese products), UPC (international products), and other major standards.
Automatic reading of delivery slips is also supported. Just photograph a paper delivery slip with your phone, and AI automatically recognizes the product name, quantity, and unit price.
There is also an automatic reorder alert. Set a threshold for each product -- "reorder when stock drops to X units" -- and you get notified automatically when inventory runs low. Purchase orders can be created with a single click.
LINE & Slack Notifications: Never Miss What Matters
Examples of notifications you can receive on LINE:
- "Invoice #INV-042 is due in 3 days"
- "Product A is down to 5 units in stock"
- "A new lead has been registered"
- "A contract has been signed"
Setup takes just three steps. Add the Totonos official LINE account as a friend, enter the linking code, choose which notifications you want to receive, and you are done. Google Chat is also supported.
Automatic Email Ingestion: Just Forward and It Is Recorded
- Get a dedicated email address from Totonos
- Forward your invoice emails to that address
