Tradify

Best for: Small-to-midsize trade and field-service businesses (electricians, plumbers, HVAC, property maintenance, small contractors) who need a mobile-first job management tool with strong quoting → job → invoicing workflows and native mobile apps.

  2. Click Invoices: On the Settings dashboard, click the Invoices section.
  3. Click the toggle under Payment Reminders to enable text reminders: Under the Payment Reminders section in Invoices, click the toggle to turn text (SMS) reminders on or off (the help article shows the same toggle used to disable text reminders).

ZenMaid

Best for: US-based small to mid-size residential and commercial maid/cleaning business owners and office managers who need easy scheduling, recurring cleans, automated client/staff communications, GPS time tracking, and built-in invoicing/payroll calculations.

  2. Click Settings > Client Billing > Tip Requests: From Settings, go to Client Billing and select Tip Requests to view the tip-related message templates and toggles (useful when you want payment prompts tied to invoice payment).

Which tool should you choose?

Workiz

Why choose this: Workiz lets you send reminders directly from the Invoices dashboard and offers Workiz Automations to automatically follow up on overdue invoices.

Who should avoid it: The available documentation in these sources shows manual reminder actions and points to Workiz Automations but does not provide in-app channel configuration steps for email versus SMS, so users needing explicit channel-level setup details may need additional support.

Fergus

Why choose this: Fergus provides built-in Reminders with SMS and Email templates and on/off toggles in Settings → Reminders, letting you automate invoice follow-ups from a single UI.

Who should avoid it: SMS reminders require enabling the SMS settings (and SMS is a paid add-on), so businesses without the SMS add-on or on very basic plans may be unable to send SMS reminders.

Kickserv

Why choose this: Kickserv's Messaging Templates include an Invoice Reminders section with a 'Send Automatic Reminders' toggle and options to attach PDFs and send copies by text message, making automated invoice follow-ups easy to configure.

Who should avoid it: If you need highly granular conditional logic per invoice (beyond the built-in cadence and simple toggles), Kickserv's invoice reminder settings may be too limited for complex billing workflows.

Service Fusion

Why choose this: Service Fusion consolidates reminder management with Reminder Presets plus per-customer Configure Personal Communication Preferences so you can quickly enable Send Invoice Reminders across customers or by default company settings.

Who should avoid it: The provided documentation focuses on reminder presets and email reminder controls but does not show SMS-specific reminder settings, so teams needing explicit SMS configuration guidance may find the instructions incomplete.

Tradify

Why choose this: Tradify provides built-in Payment Reminders controls in both the Settings (for SMS/text) and per-invoice Payment Options (for email), letting you enable automated reminders directly inside the app without external tools.

Who should avoid it: If you need advanced, campaign-style SMS sequencing or highly granular per-invoice SMS templates, Tradify's simple toggles and basic reminder controls may be too limited for power SMS workflows.

ZenMaid

Why choose this: ZenMaid includes native automated email and SMS communications plus an Invoicing Settings page, so you can configure invoice-related messages directly inside the app.

Who should avoid it: Avoid ZenMaid for highly granular or conditional reminder automations if you need advanced scheduling logic beyond the built-in email/SMS templates and basic invoicing settings.
