Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Advisory firms have a collections problem most software doesn't solve. Fee-for-service planning, hourly engagements, and retainer billing all produce invoices that clients mean to pay and then forget, and chasing them eats hours your advisors could spend with clients. The AUM model sweeps fees automatically; direct billing doesn't, and the manual follow-up process is exactly where payments stall. Email reminders help, but open rates for payment reminders hover around 25% according to InvoicifyAI's published data, which means most clients never see them. A phone call fixes that, and in 2026 you no longer need to hire a collections temp to make it. AI-powered reminder calls can confirm an invoice arrived, surface the real blocker, capture a promise-to-pay date, and write the outcome back to your CRM. This guide compares five platforms that genuinely support payment and invoice reminder calling, evaluated on features confirmed in published research, pricing transparency, compliance posture, and fit for advisory workflows. We've flagged where each tool is strong and where it's the wrong fit, because a firm billing planning fees has different needs than a collections agency working third-party debt.

#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 AIQ Labs with a base in Halifax, Nova Scotia and an operating base in Austin, Texas. It's not 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 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 planning fees, retainer installments, and hourly invoices: a polite heads-up before the due date, then a follow-up that confirms the invoice arrived, captures a promise-to-pay date, and routes disputes or exceptions to your team. The differentiator is list discipline. Every campaign runs only against approved, permissioned, or reviewed contact lists, and list source and consent records are checked before any campaign 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. That matters for advisory firms, where client relationships and regulatory posture are both on the line. 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, renewed, opted out, no answer), per-call notes, and follow-up requests. And the no-invented-numbers policy means you only see what actually happened on every call.

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

#2 CloudTalk — Contact for pricing. CloudTalk advertises a free 50 AI minutes trial and a 14-day trial with no card required.

CloudTalk offers an AI voice agent built specifically for automated payment reminder calls, positioned inside a full business phone system. According to their website, the agent calls customers before and after the invoice due date, states the balance, sends the customer to your payment link, portal, or IVR, and logs the outcome in your CRM. Disputes and payment plan requests go to your team, which is the right handoff for advisory firms where a fee dispute needs an advisor or compliance officer, not a script. CloudTalk emphasizes that card details stay off the call, and that recordings, transcripts, and call outcomes are encrypted. The company states it is compliant with GDPR, ISO 27001, SOC 2, and CCPA, with 99.999% uptime. The AI can introduce itself as an AI assistant in its first sentence, which supports disclosure requirements. Setup is handled with a solutions consultant who builds the reminder flow with you and connects billing or CRM triggers, with most teams live in one to two weeks, no code required. CloudTalk also supports 70+ languages and local numbers in 160+ countries, and connects natively to HubSpot, Salesforce, Pipedrive, Zoho, and 100+ more systems. For advisory firms already running a CloudTalk phone system, the reminder agent is a natural extension rather than another vendor to manage.

Best for: AR and billing teams at advisory firms that want reminder calling inside a full business phone system, with strong CRM integration and multilingual support.

#3 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 plan is $99 USD/month. 7-day free trial available.

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 advisory firms, that response-oriented model fits a familiar problem: the client who says they never received the planning-fee invoice, or the payment stuck in a household's internal approval while the engagement continues. 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, with follow-up auto-scheduled if payment is still outstanding after a promised date. Payment instructions already stored on the invoice, including links, can be shared during the call. Outcomes are logged cleanly: promise-to-pay dates, blockers, voicemail results, and full transcripts attach to the invoice and CRM records, and exceptions escalate to your team only when a person should step in. InvoicifyAI positions this as a layer on top of your existing invoicing process rather than a full accounts receivable platform, so teams should confirm how outcomes sync with their billing stack. Pricing is published: the agent is included in the Pro plan at $149 USD/month (400 shared AI voice minutes, then $0.35/min overage) and in the Business plan; the Starter plan is $99 USD/month.

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

#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 their 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 for someone to clear 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 reminders get seen without bombarding customers. The platform integrates with accounting software such as Xero and QuickBooks Online, which fits advisory firms that already run firm 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 their site credit it with improving debtor days. One honest caveat: Auto-call delivers pre-scripted messages rather than holding a two-way conversation, so it can't capture a promise-to-pay date or handle a fee dispute the way a conversational agent can. For firms that want consistent, scheduled reminder calls with the conversation handled by advisors when it matters, that trade-off may be acceptable. 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 at advisory firms using Xero or QuickBooks that want scheduled phone, SMS, and email reminder sequences without manual dialing.

#5 Sono — Contact for pricing. Sono describes its model 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: a confirmation SMS to the customer, plus disposition, promised date, and transcript against the account. Sono identifies as an AI assistant on calls, honors calling-hour rules and do-not-call flags, and stores a transcript and recording of every call against the account for audit. The company publishes measured results from its 2026 European consumer-credit calling programme, including a 48.9% answer rate and 70% of commitments becoming a payment, while noting that recovery rates vary by portfolio. Pricing is described on their site as a flat monthly fee plus usage, with custom quotes.

Best for: Firms with a meaningful overdue ledger that want early, consistent contact on every account before invoices age into collections.

The right payment reminder call solution for an advisory firm depends on what you're actually trying to fix. If your invoices are mostly fine and you just want scheduled, pre-scripted nudges on top of Xero or QuickBooks, Chaser's Auto-call does that job at a published price. If you want a conversational agent that captures promise-to-pay dates and logs outcomes, InvoicifyAI and CloudTalk both deliver, with CloudTalk offering the broadest CRM and phone-system integration and InvoicifyAI offering the clearest published pricing. Sono is strongest when the problem is a large overdue ledger that nobody has time to work. My AI Call Center earns the top spot for a different reason: it's the only option on this list that is a managed service rather than software you have to run. For advisory firms, that matters. You get campaigns scoped around one clear goal, quoted in full before launch, run only against approved, permissioned, or reviewed client lists, with consent records checked before a single call goes out. AI disclosure, immediate opt-outs, DNC handling, and state-specific quiet hours are built in, and the outcome report shows exactly what happened, with no invented numbers. Calling starts at 9¢ per connected minute, tiered by volume, with no per-seat charges and no minimums you didn't choose. The first campaign review is free, and you'll know the full number before approving launch. If chasing late planning fees is eating your advisors' week, that review is a low-cost place to start.
