✦ The Concept
Your business runs on trust.
Your business runs on trust.
SpenzaBook makes it visible.
Every time you give credit to a customer or receive goods on account from a supplier, money moves without changing hands. SpenzaBook captures that invisible flow — and makes sure nothing slips through.
- One tap to record a "gave money" or "received money" entry
- Separate ledgers for customers (debtors) and suppliers (creditors)
- AI-generated reminders so you never have an awkward chase conversation
- Real-time balance for every contact — never do mental math again
- Attach bill photos, voice notes or invoice numbers to any entry
✦ Customer Ledger
Every rupee given — tracked, reminded, recovered.
Stop relying on memory or notebooks. SpenzaBook's customer ledger gives you a clear, permanent record of every credit transaction.

AI-Timed Reminders
Instead of spamming contacts, SpenzaBook's AI studies payment patterns to pick the exact day and hour each person is most likely to respond. Gentle, smart, effective.
Contact Credit Score
Each customer gets a hidden reliability score based on how quickly they pay. You see a simple traffic-light indicator — green, amber or red — so you know who to trust.
Bill & Receipt Attach
Snap the invoice, select from camera roll, or generate a digital receipt inside the app. Every entry has a paper trail without paper.
Private by Design
Only you and the specific contact can see their own ledger entries. No other customer sees your business relationships. End-to-end encrypted and offline-first.
One-Tap Share
Send a statement directly to a customer via WhatsApp, SMS or email — beautifully formatted, showing all entries and the net balance. No PDF export needed.
The reminder that doesn't feel like one
SpenzaBook replaces "bhai paisa de do" with a system that's polite, timely and actually works.
💬
WhatsApp Smart Reminder
AI crafts a personalized message using the customer's name and exact balance — sent at the moment they're most likely to open it.
📱
SMS Fallback
If WhatsApp is unread for 24 hours, an SMS goes out automatically. No manual follow-up from you, ever.
✦
Escalation Pausing
AI detects if a contact is going through a rough patch (missed multiple payments) and pauses reminders — protecting your relationship, not just your money.

SpenzaBook AI says:
"Ravi Kumar has paid within 72 hours on 8 of his last 10 entries. He's due ₹2,500. Sending a WhatsApp reminder on Thursday at 11 AM gives you an 84% recovery probability."
✦ Supplier Ledger
Never miss a supplier payment — or overpay one.
Track every purchase you make from every supplier. SpenzaBook keeps a running account of what you owe, alerts you before payment deadlines, and even spots which supplier is charging you more than market rate.
- Log purchases (what you bought) and payments (what you paid)
- AI compares your per-unit costs across suppliers over time
- Payment due date alerts — never pay a late fee again
- Monthly purchase summary per supplier, exportable to PDF
- Attach delivery notes or invoices to every purchase entry
✦ Reports & Cashbook
Your business finances, on one screen.
SpenzaBook automatically builds reports from every entry. No accountant. No spreadsheet. Just clarity.

SpenzaBook — your questions answered
Is SpenzaBook different from the main Spenzaa expense tracker?
Yes — but they work together. Spenzaa tracks your personal and business expenses (bills, subscriptions, income). SpenzaBook is the ledger layer: it handles credit you extend to customers and purchases you make from suppliers. Both live inside the same app, with a shared AI engine and cloud backup.
Does the customer see my other business contacts or amounts?
Never. Each contact can only see entries you share with them directly. The ledger is private by default — only you see the full picture across all contacts.
Can I use SpenzaBook for personal lending too (friends & family)?
Absolutely. It works just as well for "I lent my friend ₹500" as for formal business credit. The AI reminders are optional — you can turn them off for personal contacts and handle it yourself.
What happens if I lose my phone?
Nothing is lost. SpenzaBook syncs every entry to your Spenzaa cloud account in real time. Log into the app on a new device, and your entire ledger restores instantly.
How does the AI decide when to send a reminder?
It analyzes the contact's historical response patterns — what day and hour they've responded in the past, how quickly they typically pay, and how overdue the balance is. It then picks the single best moment to send, rather than a fixed time like most apps.
Is SpenzaBook free?
The core ledger — unlimited contacts, unlimited entries, bill photos and basic reports — is free forever. AI-timed reminders, contact credit scores, supplier cost comparison and advanced cash flow prediction are part of the Spenzaa Pro plan.
✦ SpenzaBook + Spenzaa
Your expense tracker and business ledger — one app.
Stop switching between apps. SpenzaBook lives inside Spenzaa — personal finance and business credit, under one AI engine.
