Best Payment & Invoice Reminder Calls for Investment Advisory Firms

For an investment advisory firm, a late fee invoice is a cash flow problem with a compliance shadow. You need the money, yes, but you also need to protect the client relationship and ensure your outreach meets regulatory standards. If you are charging fee-for-service planning fees, AUM management fees, or retainer invoices, the billing cycle is often where the rubber meets the road. Email reminders are the default, but they have a low open rate and zero conversational power. They do not let you ask if the invoice arrived, if there is a dispute, or if the payment is stuck in internal approval. A phone call does. It surfaces the real blocker in real time and gets a specific commitment on a date. In 2026, the best solution is not a human dialing hundreds of numbers a day, but a structured, AI-powered calling campaign that runs on approved lists, respects consent records, and logs every outcome back into your CRM. We evaluated five platforms that help investment advisory firms run payment and invoice reminder calls. We looked at compliance posture, pricing transparency, and how well each tool fits the specific billing workflows of financial advisors.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. The first campaign review is free.

My AI Call Center is a done-for-you managed outbound calling service that runs structured AI-powered campaigns against approved, permissioned, or reviewed contact lists. For investment advisory firms, the Payment & Invoice Reminder Calls campaign is designed to place calls a few days before an invoice due date, with structured follow-up if the payment remains unpaid. This maps directly onto how advisory firms chase retainer fees, planning invoices, and AUM management charges. Unlike software you have to configure and staff, you buy campaigns that the team runs for you, each scoped around one clear goal and quoted in full before launch. The service is owned and operated by AIQ Labs, with a base in Halifax, Nova Scotia, and an operating presence in Austin, Texas. The primary differentiator is list discipline. Every campaign runs only against lists where the source and consent records are checked before launch. If a list lacks clear permission records, it is flagged and often declined. This protects your firm's compliance posture, which is critical in the financial services industry. Compliance is built into every call: AI-generated voices are treated as artificial voices under the TCPA, prior express consent is required, and AI disclosure appears on every call. Keyword opt-outs are honored immediately, and state-specific quiet hours are respected. Outcomes route back into your existing CRM and scheduling tools with named disposition codes, per-call notes, and follow-up requests. The no-invented-numbers policy means you only see what actually happened on every call, providing a clean audit trail.

Best for: Investment advisory firms and multi-location financial service organizations (1–200+ staff) that want managed, compliance-forward reminder calling against approved client lists 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) and the Business plan. The Starter plan is $99 USD/month.

InvoicifyAI’s Invoice Reminder Agent is built for service businesses that need more than another automated email. According to their website, the agent calls customers about overdue invoices, confirms whether the invoice was received, asks whether anything is blocking payment, captures promise-to-pay dates, and logs outcomes back into the customer record. For investment advisory firms, this response-oriented model fits a familiar problem: the client who says they never received the invoice, or the payment stuck in internal approval while your vendor deposits come due. The agent follows a structured cadence, with a Day 1 friendly reminder call, a Day 7 follow-up with commitment, a Day 14 escalation call, and a Day 30 final notice, and follow-up is auto-scheduled if payment is still outstanding after a promised date. The platform emphasizes clean outcomes: promise-to-pay dates, blockers, voicemail results, and full transcripts are logged to the invoice and CRM records, and exceptions escalate to your team only when a person should step in. The agent also shares payment instructions already stored on the invoice, including links when available. InvoicifyAI positions this as CRM-ready outcome logging, so call results connect to customer history rather than getting lost in a spreadsheet. It is a focused tool for voice follow-up as a layer on top of your existing invoicing process, rather than a full accounts receivable platform. However, it is built around general service-business invoicing rather than financial advisory workflows, so teams should confirm how outcomes sync with their existing billing stack and compliance requirements.

Best for: Service businesses, agencies, and financial advisory teams that want polite voice follow-up on overdue invoices with payment commitment capture and CRM-ready outcomes.

#3 Sono — Contact for pricing (described on their site as a flat monthly fee plus usage).

Sono provides AI payment reminder calls positioned squarely in the window between an invoice falling overdue and a handover to collections, a period the company describes as 'nobody's job.' According to their website, Sono connects to your billing, ERP, or AR platform (or a scheduled file), picks up every account the moment it ages past your trigger, and places short, polite calls on a cadence you configure. For example, you can set calls for day 3, day 10, or day 25, with retries at different hours until it reaches a person. On each call, the agent confirms the customer knows what is outstanding, clears whatever is blocking payment (resending the invoice, correcting a reference, confirming the amount, or taking a dispute off the table), and agrees a payment date the customer commits to. Every outcome is written back to your systems. This is a strong option for investment advisory firms that want to automate the initial follow-up without involving a human collector. The platform is designed to handle the 'awkward middle' of collections, where you want to be polite but persistent. However, Sono is a specialized AR tool, and its focus is on the collection workflow rather than the broader relationship management context that advisory firms often prioritize. It is a good fit if your main pain point is the gap between an overdue invoice and a formal collections notice.

Best for: Investment advisory firms and other businesses that want automated, polite voice follow-up in the window between an invoice going overdue and a handover to collections.

#4 Chaser — Compact plan from A$399/month according to their website; free trial available.

Chaser is an accounts receivable automation platform that includes Auto-call, a feature designed to reduce manual intervention when chasing late payments. According to Chaser, Auto-call lets finance teams schedule automated phone calls that deliver pre-scripted, text-to-speech payment reminders on the times and days they choose. Each call is personalized to the recipient, and because calls are placed instantly on schedule, teams can follow up on overdue invoices without waiting until they have cleared their to-do list. Chaser also supports a multi-channel approach, allowing businesses to schedule phone call, SMS, and email reminders in one system so payment reminders get seen without bombarding customers. The platform integrates with accounting software such as Xero and QuickBooks Online, which makes it a practical fit for investment advisory firms that already run their invoicing through those tools. Chaser reports that over 10,000 users worldwide rely on the platform to get paid faster and protect cash flow. While Auto-call is not a conversational AI agent (it delivers pre-scripted messages rather than holding a two-way dialogue), it is a solid option for advisory businesses that want consistent, automated call reminders without asking office staff to dial manually. This is a good choice if you prefer a structured, multi-channel approach over a conversational AI agent.

Best for: Finance teams and investment advisory firms using Xero or QuickBooks that want automated phone, SMS, and email reminder sequences without manual chasing.

#5 Paidnice — Contact for pricing.

Paidnice focuses on accounts receivable automation for Xero and QuickBooks users. It is useful when reminders, statements, payment plans, and accounting-system writeback matter. According to research, Paidnice runs the reminders, late fees, and statements for Xero and QuickBooks businesses automatically. The platform is designed to handle the routine aspects of dunning, including sending statements and managing overdue-invoice visibility. It is a strong fit for investment advisory firms that use Xero or QuickBooks as their primary accounting ledger and want to streamline the reminder process. Paidnice is particularly effective when the goal is to maintain accounting-system writeback, ensuring that payment status is always up to date in your ledger. However, if your main problem is a customer ignoring emails and needing a phone conversation, you should verify that the workflow covers the channel you actually need. Paidnice is a finance-process oriented tool, which means it is best suited for teams that prioritize accounting accuracy and statement generation over conversational follow-up. It is a solid option for firms that want to automate the backend of their billing process but may need to supplement it with a separate tool for complex, high-value client conversations.

Best for: Investment advisory firms using Xero or QuickBooks that want AR automation, statements, and reminders with accounting-system writeback.

Choosing the right payment reminder tool for your investment advisory firm comes down to balancing compliance, cost, and the level of automation you can manage. If you want a done-for-you service that handles the entire calling process, from list review to outcome reporting, My AI Call Center is the clear choice. It is built for compliance-first environments and gives you a clear, locked price before you launch. If you prefer to stay in control of the software and use a tool that integrates with your existing accounting stack, InvoicifyAI or Chaser are strong options. Sono is a good fit if you want to automate the pre-collections window, and Paidnice is ideal for firms that prioritize accounting writeback and statement generation. The key is to match the tool to your workflow. Do not assume that a generic AR tool will handle the specific nuances of financial advisory billing. Test the draft, approval, and overdue invoice flows before you go live. Remember that a payment reminder is only useful when the underlying receivable is correct. Ensure your client entity, engagement, and invoice owner all agree before you automate the outreach. If you are ready to run more useful calls without building a bigger call center, start with a free campaign review. You will know the full number before you approve launch.
