Frequently asked questions
Is a contract signed on paper or PDF valid?
A contract signed by both parties is enforceable under the Indian Contract Act. E-signatures under the IT Act are also valid for most commercial contracts. Stamp duty may apply depending on the state and contract type.
Can I charge interest on late payment?
Yes, if agreed in the contract. For MSME-registered suppliers, the MSMED Act provides for compound interest at three times the bank rate on payments delayed beyond 45 days to buyers.
Is this tool free? Do I need to sign up?
Yes, it is completely free with no login and no limit on entries. Signing up for a free FastFee account is optional and adds sync across devices, team access, automatic reminders and online payment collection.
