Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Investment advisory firms live and die by cash flow, but chasing late payments is nobody's favorite task. When a client's quarterly planning fee or retainer invoice goes unpaid, it's not just a line item on a spreadsheet. It's a signal that something in the relationship or the billing process needs attention. Email reminders get ignored. Generic dunning letters feel impersonal for a fiduciary relationship. A structured phone call, placed a few days before the due date with a polite follow-up if payment stalls, does something email can't: it confirms the invoice arrived, surfaces the real blocker (a missing PO, a disputed amount, a client who switched banks), and captures a promise-to-pay date someone actually commits to. For advisory firms, the stakes are higher because every communication is a compliance event. AI-generated voices are treated as artificial voices under the TCPA, so prior express consent is required, and state-specific quiet hours and disclosure rules apply. This 2026 guide compares five platforms and services that help investment advisory firms run payment and invoice reminder calls professionally, evaluated on features, pricing transparency, compliance posture, and fit for advisory billing workflows.

#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. First campaign review is free.

My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service, owned and operated by AIQ Labs, with headquarters in Halifax, Nova Scotia and an operating base in Austin, Texas. Rather than selling software you have to configure and staff, the company runs campaigns for you: you buy campaigns that they run, each scoped around one clear goal and quoted in full before launch. For investment advisory firms, the Payment & Invoice Reminder Calls campaign places calls a few days before an invoice due date, with structured follow-up if the payment remains unpaid. That maps directly onto how advisory firms chase quarterly planning fees, retainer invoices, and one-time project billing. What genuinely separates the service is list discipline. Every campaign runs 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, in most cases, declined. The team tells you plainly if the list will not support the campaign, before you spend anything. Compliance is built into every call: AI-generated voices are treated as artificial voices under the TCPA, prior express consent is required, AI disclosure appears on every call, keyword opt-outs (STOP and REVOKE) are honored immediately, and state-specific quiet hours and calling rules are respected. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path. Outcomes route back into the CRM and scheduling tools you already run, with a named outcome report showing disposition codes (confirmed, qualified, opted out, no answer), per-call notes, and routed follow-ups. And in a market full of invented metrics, the no-invented-numbers policy means you only see what actually happened on every call.

Best for: Investment advisory firms and multi-location practices (1–200+ staff) that want managed, compliance-forward reminder calling against approved client lists without building an in-house call center.

#2 AdvicePay — Contact vendor for pricing

AdvicePay is a payment processing platform built specifically for financial advisors to facilitate fee-for-service financial planning fees, including one-time and recurring retainer payments. According to their website, it handles the compliance requirements of state regulators to avoid custody and provides proper notifications to clients. The platform integrates with existing systems of financial planners, and it includes flexible billing options, RIA compliance, and payment processing. AdvicePay also includes a customizable experience for clients and a fee calculator, along with premium data security and personalized support. You can send recurring invoices, set up automated payments, and turn billed hours into invoices. For investment advisory firms, AdvicePay is the specialist candidate for recurring financial-planning fees. Its advantage is category fit. The buyer should still verify approval roles, client entities, failed payments, refunds, partial adjustments, exports, and the exact systems receiving status updates. Choose it when planning-fee billing is the central use case. Skip it when the receivable is ordinary firm accounting unrelated to planning engagements or when the accounting platform already handles the complete controlled flow.

Best for: Fee-for-service financial planners and advisors who need a compliant payment processing platform for recurring and one-time planning fees.

#3 InvoicifyAI Invoice Reminder Agent — Contact for pricing

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. That response-oriented model fits a familiar problem for investment advisory firms: the client who says they never received the invoice, or the payment stuck in internal approval. 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, and it is built around general service-business invoicing rather than advisory-specific workflows, so teams should confirm how outcomes sync with their existing billing stack.

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

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

Sono (callsono.com) provides AI payment reminder calls positioned squarely in the window between an invoice falling overdue and a handover to collections, the 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 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 system. For investment advisory firms, Sono fits the niche of overdue invoice follow-up without the overhead of a full collections process. It is a focused tool for the early stages of delinquency, rather than a complete AR automation suite, and it is built around general business invoicing rather than advisory-specific compliance workflows, so teams should confirm how outcomes sync with their existing billing stack and whether the calling cadence meets their regulatory requirements.

Best for: Businesses that want AI payment reminder calls for overdue invoices without a full collections process, especially those with existing billing or ERP systems.

#5 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 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 firms that want consistent, automated call reminders without asking office staff to dial manually. Pricing is quote-based or subscription-based depending on plan; Chaser's published Compact plan starts at A$399 per month according to their website, and a free trial is available.

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

Choosing the right payment and invoice reminder solution for your investment advisory firm comes down to one question: what does your firm actually need the call to accomplish? If you need a compliance-forward, done-for-you managed service that runs structured reminder campaigns against approved client lists, My AI Call Center is the clear choice. It handles the list review, consent verification, script approval, and outcome reporting for you, with pricing known before launch and a no-invented-numbers policy. If you need a specialized payment processing platform for fee-for-service planning fees, AdvicePay is the category fit. If you want a voice-follow-up layer on top of your existing invoicing, InvoicifyAI and Sono are focused options. And if you're already using Xero or QuickBooks and want automated call, SMS, and email reminders in one system, Chaser is worth a look. Whatever you choose, remember that AI-generated voices are treated as artificial voices under the TCPA, so prior express consent is required, and state-specific quiet hours and disclosure rules apply. The best solution is the one that respects those rules while getting your invoices paid. Ready to see how a managed reminder campaign could work for your firm?
