Is my data secure and is this site safe?

Yes. InvoiceNudge operates with a strict Zero Server Storage architecture. All invoice amounts, client names, banking details, and emails are processed strictly in your browser's private JavaScript memory. No data is sent to external servers or databases.

When should I send the first payment reminder?

The optimal window for a First Notice (Gentle Reminder) is 1 to 3 business days following the maturity due date, assuming an innocent administrative delay and re-attaching invoice documentation.

Can I legally charge late fees or interest if they weren't in my contract?

Yes, in most commercial jurisdictions through statutory prejudgment interest and prompt payment legislation such as UCC Article 2 merchant benchmarks (18% APR), California Civil Code § 3287 (10% APR), and the UK/EU Late Payment of Commercial Debts Act.

What should I do if the client completely ignores my notices?

Follow a progressive escalation ladder: Accounts payable escalation, deliverable and service freeze, formal final demand letter with a 7-day cure period, and subsequently small claims filing or commercial debt collection.
