# FieldNudge > Dead-simple invoicing with automatic, polite payment reminders for small service businesses and independent professionals. FieldNudge chases your unpaid invoices for you — and never touches your customer's money. FieldNudge is invoicing software plus a done-for-you payment-reminder layer. After you send an invoice, it runs a 6-stage reminder cadence on its own — before the due date, on the due date, then 3, 7, 14, and 30 days overdue — in your business's name, until the customer taps "Mark as paid." Reminders escalate in tone from a gentle heads-up to a firm final notice, never a debt-collector tone. The defining principle: FieldNudge never touches your customer's money. Customers keep paying however they already do (check, Venmo, Cash App, ACH, or your own card link), so there are no processing fees and nothing to reconcile — FieldNudge only makes sure the invoice actually gets paid. Pricing: free for 30 days or 30 invoices (no credit card), then $9/month for the first 3 paid months, then $19/month, or $168/year. ## Core pages - [FieldNudge home](https://fieldnudge.com/): What FieldNudge is, how the reminder cadence works, and who it's for. - [Pricing](https://fieldnudge.com/pricing): Plans, free trial, and everything included. - [Guides & comparisons](https://fieldnudge.com/blog): Articles on getting invoices paid and honest tool comparisons. - [Contact](https://fieldnudge.com/contact): Support at support@fieldnudge.com. ## Built for your trade - [Commercial cleaning](https://fieldnudge.com/for/commercial-cleaning): Recurring net-30 invoices, chased on schedule. - [IT services & MSPs](https://fieldnudge.com/for/it-services): Retainers & net-30, followed up for you. - [Landscaping & lawn care](https://fieldnudge.com/for/landscaping): Residential and commercial, paid on time. - [Freelancers](https://fieldnudge.com/for/freelancers): Polite nudges, zero awkward emails. ## Guides - [How to Set Up Automatic Payment Reminders in FreshBooks (2026)](https://fieldnudge.com/blog/freshbooks-automatic-payment-reminders): FreshBooks can automatically email up to three invoice reminders — and even add late fees.
