Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Advisory firms live on recurring fees, and when a planning fee or advisory invoice goes unpaid, the follow-up work usually lands on someone who would rather be meeting clients. Email reminders are easy to ignore: open rates for payment reminders hover around 25%, according to InvoicifyAI's research, which means three out of four clients never see your nudge. A short, polite phone call does what email can't. It confirms the invoice actually reached the right person, surfaces the real blocker (a disputed amount, a missing approval, a client who simply forgot), and ends with a specific promise-to-pay date. For investment advisory firms, though, the stakes are higher than average cash flow. You're calling clients whose relationships matter enormously, often about sensitive financial matters, so compliance, tone, and consent handling aren't optional. This 2026 guide compares five solutions that handle payment and invoice reminder calls, evaluated on features confirmed by each vendor's own materials, pricing transparency, compliance posture, and fit for advisory billing workflows. Some are managed services that run the calls for you. Others are software you operate in-house. The right choice depends on how much of the process you want to own.

#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 (myaicallcenter.app) is a done-for-you managed outbound calling service owned and operated by AI Labs, based in Halifax, Nova Scotia with an operating base in Austin, Texas. Rather than selling 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. For 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. 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 won't support the campaign, before you spend anything. For advisory firms calling clients about fees, that consent-first posture matters, especially since AI-generated voices are treated as artificial voices under the TCPA and prior express consent is required. Compliance is built into every call: AI disclosure appears on every call, keyword opt-outs (STOP and REVOKE) are honored immediately, state-specific quiet hours are respected, and DNC requests carry across all campaigns. 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, 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 organizations (1 to 200+ staff) that want managed, compliance-forward reminder calling against approved client lists without building an in-house call center.

#2 AdvicePay — Contact for pricing (quote plus payment fees, per the 2026 US Tech Automations review).

AdvicePay is the specialist candidate for advisory firms charging financial-planning fees through invoices or subscriptions, and US Tech Automations' 2026 review scores it highest among the tools evaluated for advisor payment reminders (5/5 on invoice ownership, reminder control, and advisor context). Its advantage is category fit: the platform is built around the way advisory firms actually bill, including recurring planning fees tied to engagements rather than generic product invoicing. According to the review, AdvicePay fits when planning-fee billing is the central use case. The reviewer's guidance is worth heeding: buyers should still verify approval roles, client entities, failed payments, refunds, partial adjustments, exports, and exactly which systems receive status updates before committing. The review also stresses a principle that applies to any reminder tool in this space: the reminder system should not calculate advisory fees from assets or decide whether an invoice is valid, and firms should test scenarios like draft invoices, overdue invoices, partial payments, disputed amounts, duplicates, and write-offs before go-live. One limitation to note: AdvicePay's research documentation does not confirm automated voice call capabilities for payment reminders. Its reminder strength is in controlled, compliant billing notifications tied to the invoice record. If your firm's biggest gap is clients ignoring email reminders and needing an actual phone conversation, you may want to pair AdvicePay with a calling service. Pricing is not published; US Tech Automations lists it as contact-for-vendor with firm/client scope and a quote plus payment fee structure.

Best for: Advisory firms whose central need is compliant planning-fee billing with controlled reminders, rather than voice-based collections.

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

Chaser is an accounts receivable automation platform whose Auto-call feature schedules automated phone calls that deliver pre-scripted payment reminders, according to their website. You write call templates, and Chaser places calls using text-to-speech on the times and days you choose, personalized to each recipient. The company positions this as a way to follow up on overdue invoices without waiting until someone clears their to-do list, and reports that over 10,000 users worldwide rely on the platform to get paid faster. For advisory firms, the practical draw is the multi-channel approach. Chaser lets you schedule phone call, SMS, and email reminders in one system, building a coordinated sequence without bombarding clients. The platform integrates with accounting software including Xero and QuickBooks Online, which suits firms that already run their invoicing through those tools. Customer testimonials on the site report improvements to debtor days and faster client responses. Be clear about what Auto-call is and isn't. It delivers pre-scripted text-to-speech messages rather than holding a two-way conversation, so it can't capture a promise-to-pay date or handle a client who says the invoice never arrived. It's a solid option for consistent, automated reminder calls without manual dialing, best paired with a process for the conversations that need a human. Chaser's published Compact plan starts at A$399 per month according to their website, and a free trial is available.

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

#4 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; Starter is $99 USD/month, per their website.

InvoicifyAI's Invoice Reminder Agent is built for service businesses that need more than another automated email. According to their website, the agent calls clients 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 advisory problem: the client who says they never got the invoice, or the payment stuck while a household waits on internal approval. The agent follows a structured cadence: a Day 1 friendly reminder call, a Day 7 follow-up with commitment, a Day 14 escalation call, and a Day 30 final notice. If a client promises to pay by a date and the payment doesn't arrive, follow-up is auto-scheduled. 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 when a person should step in. The agent also shares payment instructions already stored on the invoice, including links when available. The Invoice Reminder Agent is included in the Pro plan at $149 USD/month (400 shared AI voice minutes, then $0.35/min overage) and the Business plan, per InvoicifyAI's website; the Starter plan is $99 USD/month. It's a focused tool for voice follow-up layered on top of your existing invoicing process rather than a full AR platform, and it's built around general service-business invoicing rather than advisory-specific workflows, so confirm how outcomes sync with your billing stack.

Best for: Advisory firms and service businesses that want polite voice follow-up on overdue invoices with payment commitment capture and CRM-ready outcomes.

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

Sono (callsono.com) provides AI payment reminder calls aimed squarely at 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 day 3, day 10, or day 25, with retries at different hours until it reaches a person. On each call, the agent confirms the client knows what's 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 client commits to. Every outcome is written back to your system, with a confirmation SMS to the client and the disposition, promised date, and transcript on your side. Sono reports figures from its 2026 European consumer-credit calling program, including a 43.6% commitment rate at day 3 and a 70% commitment-to-payment rate, though it notes these are measured on one program and applied to your book they're a model, not a guarantee. The company also emphasizes compliance basics: the agent identifies as an AI assistant, honors calling-hour rules and do-not-call flags, follows your disclosure wording, and stores a transcript and recording against each account. Pricing is described as a flat monthly fee plus usage, with no public rates, so contact Sono for a quote. It's a strong fit for firms with a meaningful volume of overdue receivables; smaller practices with occasional late invoices may not need this much machinery.

Best for: Firms with a steady volume of overdue invoices that want systematic coverage of the whole overdue book before any escalation to collections.

The right reminder solution depends on how you bill and who you're calling. If your firm bills planning fees through a dedicated platform, AdvicePay gives you controlled, category-fit reminders tied to the invoice record. If you run invoicing through Xero or QuickBooks and want scheduled calls plus SMS and email in one place, Chaser is the practical pick. If your main problem is getting a response after emails go ignored, InvoicifyAI's Invoice Reminder Agent captures promise-to-pay dates and blockers in a real conversation. And if you have a steady stream of overdue receivables, Sono works the whole book on a cadence you set. For most advisory firms, though, the deciding factors are consent, compliance, and not adding another system to manage. That's where My AI Call Center stands apart. It's a managed service: you bring the goal, they review your list and consent records, quote the full campaign before launch, and run calls only against approved, permissioned contacts, with AI disclosure on every call and outcomes routed back into your CRM with disposition codes you can actually act on. Pricing starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign and no minimums you didn't choose. The first campaign review is free, so you'll know the full number before you approve anything. If you'd rather stop chasing invoices and start getting clear answers on every unpaid fee, start with a campaign review at myaicallcenter.app.
