FastFee vs MyBillBook — FAQ
What is the difference between FastFee and MyBillBook?
MyBillBook is a GST billing app — it creates invoices, tracks party-wise ledger, manages inventory, and handles basic accounting. FastFee is a collection and recovery platform — it sends automated WhatsApp reminders for outstanding dues, sets up UPI AutoPay mandates, tracks DPD aging (0-90+ days), and manages Promise-to-Pay commitments. MyBillBook records what is owed; FastFee ensures it gets paid.
Does MyBillBook have automated WhatsApp payment reminders?
MyBillBook allows manual sharing of invoices on WhatsApp but does not offer automated, scheduled WhatsApp reminder sequences for overdue payments. FastFee sends automated WhatsApp reminders at Day 3, Day 7, and Day 15 after a due date, with AI escalation sequences for chronic defaulters — fully automated without any manual effort.
Is FastFee Free as good as MyBillBook Free?
FastFee Free and MyBillBook Free serve different needs. FastFee Free offers GST billing, WhatsApp reminders for outstanding dues, party-wise outstanding tracking, digital receipts, and defaulter lists. MyBillBook Free offers stronger inventory tracking and accounting. For recovery-focused businesses, FastFee Free is better. For accounting-heavy businesses, MyBillBook Free is stronger.
Can I use MyBillBook and FastFee at the same time?
Yes. Both have free tiers. Use MyBillBook for billing, inventory, and GST records. Use FastFee to send automated WhatsApp reminders for outstanding dues and track which customers have paid. They complement each other and do not conflict.
Which is the best MyBillBook alternative for small businesses in India?
FastFee is not a direct MyBillBook alternative for accounting. For recovery and collection, FastFee goes far beyond what MyBillBook offers: automated WhatsApp reminders, UPI AutoPay mandates, DPD aging, PTP tracking, and AI escalation sequences — none of which MyBillBook has. FastFee is the recovery layer that works alongside MyBillBook's billing layer.
