Travel nurse staffing agencies operate in a high-velocity environment where cash flow can stall just as quickly as it moves. While your recruiters are busy placing clinicians and your finance team is managing multi-state payroll, invoices to hospitals and healthcare systems often sit unpaid for 30 to 90 days. Manual follow-up is inefficient, prone to human error, and can damage client relationships if the tone is off. In 2026, the best payment and invoice reminder calls are those that are automated, compliant, and context-aware. They should confirm the invoice was received, identify blockers like missing POs or internal approval delays, and secure a specific promise-to-pay date without requiring your staff to make awkward collection calls. This listicle reviews the top five solutions for travel nurse staffing agencies, focusing on platforms that handle the heavy lifting of accounts receivable follow-up while protecting your client relationships.
#1 My AI Call Center — Calling starts at 9 cents per connected minute, tiered by volume. Most campaigns include a one-time setup fee and a flat monthly management fee, both quoted before launch.
My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service owned and operated by AIQ Labs, with bases in Halifax, Nova Scotia, and Austin, Texas. Unlike software platforms that require you to configure scripts and manage integrations, this service runs campaigns for you. For travel nurse staffing agencies, the Payment & Invoice Reminder Calls campaign places structured calls a few days before an invoice due date, with follow-up if the payment remains unpaid. This maps directly onto the billing cycles of healthcare facilities, helping you chase deposits, milestone payments, and final balances without hiring a collections team. The service is built on a foundation of list discipline, running only against approved, permissioned, or reviewed contact lists. List source and consent records are checked before any campaign launches, and bought lists without clear permission records are flagged and often declined. Compliance is integrated into every call, with AI disclosure on every interaction, strict adherence to TCPA regulations, and immediate honoring of keyword opt-outs. Outcomes route back into your existing CRM, providing disposition codes and per-call notes. The no-invented-numbers policy ensures you see exactly what happened, making it a reliable partner for managing receivables in a regulated industry.
Pros
- Done-for-you service eliminates the need for internal staff to manage calls
- Full pricing transparency with rates locked before the campaign starts
- Strong compliance posture protects agency reputation and legal standing
- Detailed outcome reports with disposition codes for accurate AR tracking
- List discipline ensures only permissioned contacts are called
Cons
- Not a self-serve software platform; campaigns are quoted and run by the provider
- Requires approval of scripts and escalation paths before launch, adding setup time
- Campaign requirements vary by location and consent status, requiring legal guidance
Best for: Travel nurse staffing agencies and multi-location healthcare staffing firms that want managed, compliance-forward reminder calling without building an in-house call center.
#2 InvoicifyAI Invoice Reminder Agent — Included in the Pro plan at $149 USD/month (400 shared AI voice minutes, then $0.35/min overage). The Starter plan is $99 USD/month.
InvoicifyAI offers an Invoice Reminder Agent designed for service businesses that need response-oriented follow-up. According to their website, the agent goes beyond automated email reminders by calling customers about overdue invoices, confirming receipt, and asking about payment blockers. It captures promise-to-pay dates and logs outcomes back into the customer record. This is a strong fit for staffing agencies where email reminders are often ignored or lost in the noise of hospital AP departments. The agent is positioned as a tool for contractors and agencies that need voice follow-up to get a real response. It helps capture payment promises and blockers, which is critical for managing the cash flow of a staffing firm. The platform integrates with CRM and customer history, allowing you to see the full context of a client's payment behavior. While it is a powerful tool for voice follow-up, it is best suited for teams that are ready to implement an AI agent within their existing tech stack rather than looking for a fully managed service.
Pros
- Captures specific payment promises and dates
- Logs blockers and disputes for follow-up
- Integrates with CRM for better client context
- More engaging than standard email reminders
Cons
- Requires technical setup and configuration
- Pricing includes shared minutes, which may vary based on usage
- Best for teams with existing tech infrastructure
Best for: Staffing agencies and service businesses that need voice follow-up to capture payment commitments and log blockers.
#3 Carly AI Agent — AI agents start at $35/month, with non-AI steps running free.
Carly is an AI agent that sends invoices and payment reminders, triggering them through QuickBooks, Xero, or Stripe. According to their website, Carly can create the invoice, email it to the client, and then follow up on an escalating schedule until the payment clears. It detects when payment lands and stops further reminders, sending a receipt and marking the invoice paid. This is ideal for staffing agencies that use project-based billing and want a single assistant to handle the entire accounts receivable loop. Carly works across whichever accounting tool you already use, personalizing each nudge and escalating the tone as an invoice ages. It is positioned for freelancers, consultants, and small service businesses doing project-based billing. For travel nurse staffing agencies, this could be useful for chasing invoices to smaller clinics or private practices that may not have complex AP portals. However, it is less suited for large hospital systems that require formal procurement processes and complex invoice tracking.
Pros
- Integrates with popular accounting tools like QuickBooks and Xero
- Personalizes reminders and escalates tone over time
- Automates the entire invoice-to-payment loop
- Cost-effective for small teams
Cons
- May not handle complex hospital AP portals or procurement processes
- Best for smaller, project-based billing workflows
- Requires setup and configuration of the AI agent
Best for: Small staffing agencies and service businesses that want an AI assistant to handle invoicing and payment chasing.
#4 Callsy AI Payment Reminders — Contact for pricing. A 50% off launch promo is mentioned, with a 30-day ROI guarantee.
Callsy is an AI payment reminder and dunning agent that helps collect on time while keeping the customer relationship intact. According to their website, Callsy picks up overdue invoices or failed charges from systems like Stripe, Chargebee, QuickBooks, or Xero, and starts a sequence automatically. The agent, named Emma, emails first, then escalates to voice and SMS if the invoice remains unpaid. It handles identity confirmation, asks about issues, and can send a PCI-DSS-compliant card update link during the call. This is particularly useful for staffing agencies that have clients paying via card or ACH, or for those managing subscription-based services. Callsy is positioned for B2B SaaS, agencies, and service businesses that want a clean audit trail. It claims a 41% lift in on-time payments and 56% of invoices clearing from email alone. For travel nurse staffing, this could be beneficial for chasing invoices to smaller facilities or for managing any recurring billing components. However, it is primarily focused on pre-collections (first 60 days) and hands off to collections vendors for longer defaults.
Pros
- Multi-channel approach (email, voice, SMS) increases response rates
- PCI-DSS-compliant card updates during calls
- Integrates with major billing and accounting platforms
- Supports multiple languages for diverse client bases
Cons
- Primarily focused on pre-collections (first 60 days)
- May not handle complex invoice disputes or procurement portals
- Pricing is not publicly listed, requiring a demo or quote
Best for: Staffing agencies and B2B businesses that want AI-driven payment reminders with multi-channel escalation.
#5 Invoice Butler — Contact for pricing.
Invoice Butler is an agentic AI collections platform that runs the full collections cycle autonomously. According to their website, it handles automated collections emails, complex negotiations, portal submissions, reply handling, contact discovery, and escalations. This is a robust solution for B2B companies generating roughly $10M to $100M in revenue that want invoice follow-up handled end-to-end without hiring a full-time AR clerk. It is particularly strong for companies that require complex procurement portals like Coupa, Ariba, and Tipalti. For travel nurse staffing agencies, this could be a fit if you are dealing with large hospital systems that use these specific AP portals. Invoice Butler plugs into QuickBooks, NetSuite, Stripe, and Xero for fast time-to-value. It is positioned as a tool that does the actual work of chasing payments and navigating portals, rather than just alerting your team. However, it is best suited for recurring B2B invoicing with established systems, and very small businesses or those with one-off billing processes may not fully benefit.
Pros
- Handles complex AP portals and procurement processes
- Autonomous execution reduces manual workload
- Integrates with major accounting and ERP systems
- Multi-channel outreach increases visibility
Cons
- May be overkill for small staffing agencies with simple billing
- Pricing is not publicly available
- Best for recurring B2B invoicing with established systems
Best for: Mid-to-large staffing agencies that need end-to-end invoice follow-up, especially with complex AP portals.
Choosing the right payment and invoice reminder call solution depends on your agency's size, billing complexity, and current tech stack. If you want a managed, compliance-forward service that runs the calls for you, My AI Call Center is a strong choice, especially for its list discipline and transparent pricing. If you prefer a software tool that you can configure and manage in-house, InvoicifyAI or Carly offer robust AI agents that integrate with your existing accounting systems. For larger agencies dealing with complex hospital AP portals, Invoice Butler provides an autonomous collections cycle. Regardless of the tool you choose, the key is to move from manual, inconsistent follow-up to a structured, automated process that secures payment promises and protects your client relationships. Start by evaluating your current accounts receivable workflow and identifying where the biggest bottlenecks are. Then, select a solution that addresses those specific pain points while keeping compliance at the forefront.
Frequently asked questions
What makes My AI Call Center different from other payment reminder tools?
My AI Call Center is a done-for-you managed service, not a software platform. They run the campaigns for you, with strict list discipline and consent verification before launch. This means you don't have to configure scripts, manage integrations, or worry about compliance details. They also have a no-invented-numbers policy, so you get accurate reporting on what actually happened during the calls.
How do payment reminder calls work for travel nurse staffing agencies?
Payment reminder calls are structured phone calls placed a few days before an invoice due date, with follow-up if the payment remains unpaid. The calls confirm the invoice was received, identify any blockers (like missing POs or internal approval delays), and secure a specific promise-to-pay date. This helps accelerate cash flow and reduces the need for manual follow-up by your finance team.
Are AI payment reminder calls compliant with TCPA regulations?
Yes, if they are implemented correctly. My AI Call Center, for example, treats AI-generated voices as artificial voices under the TCPA, requires prior express consent, and includes AI disclosure on every call. Keyword opt-outs are honored immediately, and state-specific quiet hours and calling rules are respected. It is important to choose a provider that has a strong compliance posture and to obtain appropriate legal guidance before launching campaigns.
What is the typical cost of payment reminder call services?
Costs vary by provider. My AI Call Center starts at 9 cents per connected minute, tiered by volume, with a one-time setup fee and a flat monthly management fee. InvoicifyAI starts at $99/month for the Starter plan, with the Invoice Reminder Agent included in the Pro plan at $149/month. Carly starts at $35/month. Callsy and Invoice Butler require contacting for pricing. It is important to compare not just the per-minute or monthly cost, but also the total cost of ownership, including setup, management, and potential overage fees.
Can payment reminder calls help with disputes or complex invoices?
Yes, but it depends on the tool. My AI Call Center routes outcomes back to your CRM, allowing your team to handle disputes or complex cases. InvoicifyAI and Callsy can capture blockers and disputes during the call, logging them for follow-up. Invoice Butler is specifically designed to handle complex negotiations and portal submissions. However, no AI tool can fully replace human judgment in resolving disputes. The goal of the call is to identify the issue and route it to the right person for resolution.
How long does it take to set up a payment reminder call campaign?
For managed services like My AI Call Center, setup involves a campaign review, list and consent review, system connection, and script approval. This can take a few days to a week, depending on the complexity of your workflow. For software tools like InvoicifyAI or Carly, setup may be faster, often taking a few hours to a day, but requires you to configure the scripts, integrations, and escalation rules yourself.
Do payment reminder calls work for both pre-due and post-due invoices?
Yes, most providers offer campaigns that cover both pre-due and post-due scenarios. My AI Call Center, for example, places calls a few days before the due date, with follow-up if the invoice stays unpaid. This proactive approach helps ensure that invoices are paid on time and reduces the number of late payments. It is important to define your cadence and escalation rules based on your client relationships and billing terms.
