B2B reorder app

Distributors reorder in a chat, and you get a clean order sheet and payment link. For: Wholesalers and manufacturers.

The problem

Reorders arrive as calls and voice notes, details get lost, credit limits live in a spreadsheet, and payments are chased by phone.

How it works

Built from: whatsapp, airtable, razorpay, claude.

• whatsapp: Where distributors already place orders
• airtable: The order and credit database
• razorpay: Payment links and settlement status
• claude: Turns messy messages into structured orders

The logic

1. When distributor sends an order: Convert it to line items and confirm quantities
2. When order exceeds the credit limit: Hold it and ask the owner to approve
3. When order confirmed: Send the invoice and a payment link
4. When dispatch made: Share the transport details
5. When payment overdue: Send a reminder and stop new orders after a limit

What can be developed

• Mobile app: Distributor app: catalogue, reorder last order, statements
• Website: Ordering portal with price lists by distributor
• Admin dashboard: Order inbox, credit limits and dispatch status; Price list and scheme management
• AI and automation: Reads voice-note and text orders; Flags unusual quantities before they are accepted

The money (illustrative example)

The customer pays ₹2499 per business, per month. API and hosting costs: WhatsApp orders ₹450, AI understanding orders ₹400, Hosting ₹150, together ₹1000. Net profit ₹1499.

Watch out for

• Orders should be confirmed back to the distributor before they are final.
• Changes to price lists must be versioned.
