  • estimates: Send professional estimates before work starts, then convert accepted estimates into invoices.

  • payments: Accept in-person, online, manual-entry, and card-on-file payments from one connected payment system.

"Having the Square app on my phone, especially if I'm doing catering, makes everything seamless. It walks you through how to send an invoice. It's nice to be able to do that on the fly. Same for payroll. If I'm out of town on a Monday, I can still run Square Payroll on my phone and just send the checks to my manager to print, which is huge. And I won't have to bring my computer with me, which is nice."

Tips to keep service payments moving


FAQ

  • What is an invoice reminder?

    Invoice reminder software sends payment follow-ups for unpaid invoices based on timing you set. With Square, reminders work inside your invoicing workflow, so you can create an invoice, add a due date, and help customers pay from the same digital invoice.

  • How do automated invoice reminders work?

    Automated invoice reminders send scheduled messages before, on, or after an invoice due date. They use the invoice's payment status, so follow-up can stop once the invoice is paid and you avoid sending unnecessary reminders.

  • Can customers pay from an invoice reminder?

    Yes. When online payments are enabled, customers can access a digital invoice to pay using eligible payment methods, including credit or debit cards, Cash App Pay, Afterpay¹, and ACH bank transfers. Payment method availability and eligibility requirements apply.

  • Can I customize invoice reminder messages?

    Yes, you can set reminder timing and include invoice details that help customers understand what they owe. Clear service descriptions, due dates, notes, and payment terms help reminders feel helpful instead of generic.

  • Can I use reminders for overdue invoices?

    Yes, invoice reminder software can follow up after a due date when an invoice is unpaid. Use overdue reminders to keep payment requests consistent, and review invoice status in Square Dashboard before taking further action.

  • Does Square support recurring invoice reminders?

    Yes, Square can support repeat billing workflows for customers you invoice regularly. You can save a customer card on file with permission, automate billing for eligible invoices, and reduce repeated manual follow-up.

  • What devices can I use to manage invoice reminders?

    You can manage invoices from Square Dashboard on a computer and from compatible Square apps on mobile devices. That helps service sellers create invoices, check payment status, and follow up from the office, on-site, or between appointments.

  • How secure are invoice payments?

    Square payment tools are built with security features that help protect payment data. Square includes encrypted payments, account protection, dispute management support, and fraud prevention tools as part of its payments platform.

  • Are invoice reminders right for service businesses?

    Square invoice reminders can help service businesses manage payment follow-up for appointments, jobs, projects, and recurring work. Contractors, cleaning services, professional services, pet services, and automotive businesses can schedule reminders and track unpaid invoices in one place.
