What is PayNudge?

PayNudge is web-based payment reminder software for small service businesses. It connects to your invoicing tools (or a CSV), sends a fixed three-step sequence of email reminders on overdue invoices — plus one-tap SMS drafts you send from your phone — and stops remaining reminders once payment is recorded in PayNudge. The wording of each step is editable; the timing is fixed.

Who is it best for?

Small businesses that invoice clients on net terms and spend time chasing late payments: freelancers, contractors and trades, agencies, consultants, bookkeepers, and accountants. It suits businesses with roughly 5–200 active clients.

What are the limits?

Payment detection is not real time: scheduled integration sync runs daily. CSV and manually entered invoices need manual payment updates. The three overdue email steps use fixed timing; only their wording is editable. PayNudge does not send SMS or WhatsApp messages, process your clients' payments, retry failed card charges, or act as a debt collection service. There is no public API or MCP integration for assistants to manage a merchant's account.

How much does it cost?

CA$2 per distinct overdue invoice when the first qualifying email is confirmed delivered to the receiving server. Remaining follow-ups for that invoice are included. Maximum CA$29 per monthly billing period before taxes; no qualifying usage means CA$0. Same CAD pricing worldwide. A 14-day free trial needs no card; after the trial, set up payment to send new paid sequences. Delivery does not guarantee reading or payment. Existing subscribers keep paid coverage; covered invoices are not charged again under usage pricing. No annual or regional plans are offered for new signups.

How does it work?

Connect Square or Stripe — or upload a CSV. PayNudge then emails a fixed sequence on each unpaid invoice: day 1, day 3 and day 7 past due, plus an optional reminder 3 days before the due date that is off by default and switched on in Settings. Each reminder sends from your business name and reply-to address, and the remaining reminders are cancelled the moment the invoice is marked paid.
