Best Payment & Invoice Reminder Calls for Investment Advisory Firms

If you run an investment advisory firm, you already know the awkward part of the business: chasing planning fees and advisory invoices. Your clients are relationships you've spent years building, so a collections call from your own team feels wrong, and an email reminder is easy to ignore in a busy inbox. The result is often the worst of both worlds: fees that age quietly while nobody follows up consistently. A structured phone call a few days before an invoice is due, with follow-up if it goes unpaid, solves what email can't. It confirms the invoice arrived, surfaces the real blocker (a disputed amount, a missing approval, a changed contact), and captures a date the client actually commits to. In 2026, advisory firms have real options here, from done-for-you managed calling services to AI voice agents and AR automation platforms. We've evaluated five solutions on features confirmed by their own websites, pricing transparency, compliance posture, and fit for the way advisory firms bill: recurring planning fees, household-based clients, and a low tolerance for clumsy outreach. Here's how they compare.

#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 (myaicallapp.com) is a done-for-you managed outbound calling service, owned and operated by AIQ Labs, based in Halifax, Nova Scotia with an operating base in Austin, Texas. It isn't software you 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 separates this service is list discipline. Every campaign runs only against approved, permissioned, or reviewed contact lists, and list source and consent records are checked before anything launches. 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 an advisory firm where client relationships are the asset, that restraint matters: no client gets an indiscriminate call. 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, and keyword opt-outs (STOP and REVOKE) are honored immediately. State-specific quiet hours and calling rules are respected, and 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, 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.

Best for: Investment advisory firms and multi-location practices (1 to 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, per InvoicifyAI's website. 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 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. For advisory firms, that response-oriented model fits a familiar problem: the client who says they never got the invoice, or the fee stuck in a household's internal discussion while your month-end closes. 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. Follow-up is auto-scheduled if payment is still outstanding after a promised date. 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. According to InvoicifyAI's published pricing, the Invoice Reminder Agent is included in the Pro plan at $149 USD per month (400 shared AI voice minutes, then $0.35 per minute overage) and the Business plan; the Starter plan is $99 per month. It's a focused tool for voice follow-up layered on top of your existing invoicing process rather than a full accounts receivable 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.

#3 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: a confirmation SMS to the client, and the disposition, promised date, and transcript to your records. Only accounts that genuinely need escalation reach collections. Sono publishes measured results 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 the company itself notes these are program measurements, not guarantees for a different portfolio. For an advisory firm, the appeal is keeping fee disputes and late fees out of the collections pipeline entirely; the relationship stays yours. Pricing is described as a flat monthly fee plus usage, so contact Sono for a quote.

Best for: Firms that want systematic coverage of their entire overdue ledger before anything reaches 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's website, 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 someone clears their to-do list. Chaser also supports a multi-channel approach, letting you schedule phone call, SMS, and email reminders in one system so payment reminders get seen without bombarding clients. The platform integrates with accounting software such as Xero and QuickBooks Online, which makes it a practical fit if your firm already runs invoicing through those tools. Chaser reports that over 10,000 users worldwide rely on the platform to get paid faster and protect cash flow, and customer testimonials on its site cite improvements to debtor days. One thing to understand before buying: Auto-call is not a conversational AI agent. It delivers pre-scripted text-to-speech messages rather than holding a two-way dialogue, so it won't capture a disputed amount or negotiate a payment date the way an agent-based tool can. It's a solid option for consistent, automated call reminders without asking staff to dial manually. Chaser's published Compact plan starts at A$399 per month according to their website, and a free trial is available.

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

#5 AdvicePay — Contact for pricing (firm/client scope quote plus payment processing fees).

AdvicePay is the specialist candidate for advisory firms charging financial-planning fees through invoices or subscriptions. According to the 2026 comparison from US Tech Automations, AdvicePay scored highest among the tools evaluated for invoice ownership, reminder control, and advisor context, precisely because it's built for the category: planning-fee billing rather than general firm accounting. Its advantage is category fit. Where general invoicing tools treat every receivable the same, AdvicePay is designed around how advisory firms actually bill: recurring planning fees, client and household entities, and the compliance sensitivities of financial advice. That said, the comparison is clear that buyers should still verify the details that matter for their practice: approval roles, client entities, failed payments, refunds, partial adjustments, exports, and the exact systems receiving status updates. It's worth understanding where AdvicePay fits in a broader stack. The comparison positions it as the system that owns the planning-fee receivable, with tools like Redtail CRM or Wealthbox providing relationship context rather than acting as the accounting ledger. It's also worth noting the reminder capability is centered on the billing workflow; firms wanting voice-based follow-up calls would pair it with a calling service. AdvicePay's pricing is listed as contact vendor, with firm and client scope determining the quote plus payment processing fees.

Best for: Advisory firms whose central need is planning-fee billing with built-in reminder workflows, rather than voice-based collections.

Advisory firms face a collections problem with a twist: the people you bill are the relationships you most want to protect. That argues for two things. First, reminder outreach that is structured, polite, and consistent, so a late planning fee gets a friendly call at day 3 instead of an awkward conversation at day 45. Second, strict consent and disclosure practices, because a clumsy or non-compliant call to a client costs more than the invoice. My AI Call Center leads this list because it handles both: managed Payment & Invoice Reminder Calls run against approved, permissioned client lists, with consent records verified before launch, AI disclosure on every call, and outcome reports routed into the CRM you already use. Pricing starts at 9¢ per connected minute, tiered by volume, with the full campaign quote known before you approve anything, and the first campaign review is free. If you'd rather own the workflow in software, InvoicifyAI, Sono, and Chaser each cover a different slice of the problem, and AdvicePay is the specialist for planning-fee billing itself. Whichever route you take, start with a single well-defined campaign, one clear goal, and a list you can stand behind.
