Investment advisory firms run on a billing pattern that punishes slow follow-up. Planning fees, retainer invoices, and one-time engagement charges often land in a client's accounts payable queue and sit there for weeks while the firm's operating costs keep coming due. The SEC's Investment Adviser Industry Snapshot counts roughly 15,396 SEC-registered advisers, and the average invoice across small businesses runs about 20 days late, according to FreshBooks research. For an RIA juggling recurring retainer fees, one-time planning engagements, and quarterly billing cycles, that gap gets expensive fast. Email reminders solve the easiest cases, but the harder ones, like the client whose invoice is stuck in internal approval, the household that never received the invoice, or the planning fee that just slipped someone's mind, usually need an actual phone call. A structured call a few days before the due date, with follow-up if payment stays unpaid, captures what email can't: confirmation the invoice arrived, the real blocker, and a promise-to-pay date someone actually commits to. This 2026 guide compares five providers 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 campaign setup fee and a flat monthly management fee, both quoted before launch. First campaign review is free.
Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time campaign 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. 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, which maps directly onto how RIAs chase retainer fees, one-time planning invoices, and recurring subscription 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, opted out, no answer), per-call notes, and routed follow-ups. In a market full of invented metrics, the no-invented-numbers policy means you only see what actually happened on every call.
Pros
- Done-for-you managed service: no seats to buy, no platform to learn, no minimums you did not choose
- Full campaign price known before approving launch, with the rate locked and never moved mid-campaign
- Strong list discipline and consent verification protect your compliance posture
- Structured outcome reporting with disposition codes routed into your existing CRM
- No invented numbers; reporting reflects exactly what happened on every call
Cons
- Not self-serve software; campaigns are quoted and run by the provider, so teams wanting instant DIY control may prefer a platform
- Campaign requirements vary by location, industry, and consent status; clients are responsible for obtaining appropriate legal guidance before launch
- Script and escalation approval before launch adds a few days to setup
Best for: Investment advisory firms, RIAs, and multi-advisor practices (1–200+ staff) that want managed, compliance-forward payment and invoice reminder calling against approved client lists without building an in-house call center.
#2 AdvicePay — Contact for pricing (firm/client scope quote plus payment processing fees). Historical published entry pricing referenced $10/month for independent advisors on the Essential plan.
AdvicePay is a payment processing platform built specifically for fee-for-service financial planners and RIAs, co-founded by Michael Kitces and the XY Planning Network. According to its site and Kitces.com coverage, the platform was created to solve the billing problem that comes with fee-for-service financial planning: managing invoices, collecting payments, and chasing late or missed retainer fees without running afoul of state custody rules. AdvicePay includes recurring and automated billing, customizable invoices, an API for integrations, approval features, and integrated payment processing designed to meet RIA compliance requirements. For investment advisory firms focused on planning-fee workflows, AdvicePay is a strong fit. The platform supports both one-time and recurring retainer fees, and positions itself as a specialist candidate for recurring financial-planning fees. According to US Tech Automations' 2026 advisor payment reminder comparison, AdvicePay scored highest for invoice ownership, reminder control, and advisor context among the products evaluated, making it the most directly aligned candidate for firms charging financial-planning fees through invoices or subscriptions. The limitation is scope. AdvicePay is built around the planning-fee billing use case rather than general firm accounting. Firms whose receivables are ordinary firm accounting unrelated to planning engagements, or whose accountant already handles the complete controlled flow in another platform, may find AdvicePay's specialist focus narrower than they need. Pricing is quote-based and tied to firm and client scope, plus payment processing fees, so the full number requires contacting the vendor.
Pros
- Purpose-built for fee-for-service financial planning and RIA compliance
- Strong fit for recurring retainer and planning-fee billing workflows
- Highest advisor-context score in 2026 advisor payment reminder evaluations
- Integrated payment processing reduces manual reconciliation
Cons
- Specialist focus means narrower fit for general firm accounting or non-planning receivables
- Pricing requires a vendor quote rather than published tiers
- Best when planning-fee billing is the central use case; less suited to broader AR operations
Best for: Fee-for-service financial planners and RIAs whose central use case is recurring planning-fee billing and who want a billing platform designed around advisor compliance.
#3 InvoicifyAI Invoice Reminder Agent — Pro plan at $149 USD/month (includes 400 shared AI voice minutes, then $0.35/min overage). Starter plan at $99 USD/month. 7-day free trial advertised.
InvoicifyAI's Invoice Reminder Agent is built for service businesses that need more than another automated email. According to InvoicifyAI's 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, that response-oriented model fits a familiar problem: the client who says they never received the planning-fee invoice, or the retainer payment stuck in internal approval. The agent follows a structured cadence. According to InvoicifyAI, the typical sequence runs 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. 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. InvoicifyAI positions this as CRM-ready outcome logging, so call results connect to customer history rather than getting lost in a spreadsheet. According to InvoicifyAI's published pricing, 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, with a Starter plan at $99 USD/month and a 7-day free trial. It is a focused tool for voice follow-up as a layer on top of an existing invoicing process rather than a full accounts receivable platform, and is built around general service-business invoicing rather than advisor-specific workflows, so firms should confirm how outcomes sync with their existing billing stack.
Pros
- Voice calls go beyond email reminders to capture real responses
- Clear structured escalation cadence with auto-scheduled follow-ups
- Outcome logging connected to customer records, not lost in spreadsheets
- Published pricing with included voice minutes and a free trial
Cons
- Built for general service-business invoicing rather than advisor-specific operations
- Best when email reminders alone are not enough; not a full AR automation suite
- Voice minutes are shared and metered, so heavy calling volumes trigger overage charges
Best for: Service businesses, agencies, and advisory firms 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 Sono's website, the platform 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. According to Sono, every outcome is written back to your system, and the agent identifies as an AI assistant, honors calling-hour rules and do-not-call flags, and stores a transcript and recording of every call against the account. Sono publishes measured figures from a 2026 European consumer-credit calling program: a 48.9% answer rate, commitments at day 3 versus day 65, and a claim that 70% of commitments become a payment. For an investment advisory firm with a recurring retainer book, the appeal is coverage: every overdue account gets a call, not just the largest balances. Pricing is not published; the site describes a flat monthly fee plus usage. The consumer-credit orientation may need configuration for advisory-firm invoicing, so firms should confirm fit before launch.
Pros
- Full coverage of the overdue book, not just large balances
- Early dispute detection instead of disputes ripening into contested files
- Auditable by default with transcripts and recordings per account
- Configurable cadence lets firms match their own payment terms
Cons
- Published performance figures come from Sono's own European consumer-credit program and may not transfer to advisory receivables
- Pricing is not published
- Consumer-credit orientation may need configuration for advisory-firm invoicing
Best for: Businesses that want systematic coverage of their whole overdue ledger before accounts reach formal collections, including advisory firms with recurring retainer books.
#5 Chaser — Compact plan from A$399/month according to Chaser's 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 calls, 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. According to Chaser's published pricing, the Compact plan starts at A$399 per month, and a free trial is available. The trade-off is that text-to-speech calls cannot capture promise-to-pay dates or resolve blockers in real time the way a conversational agent can, so firms with complex client billing situations may need a follow-up layer.
Pros
- Automated phone calls remove the need for manual dialing
- Multi-channel scheduling keeps reminders coordinated across phone, SMS, and email
- Xero and QuickBooks integrations fit existing accounting workflows
- Personalized text-to-speech templates save preparation time
Cons
- Pre-scripted text-to-speech is not a conversational AI agent
- Pricing may be better suited to larger AR teams than small advisory practices
- Cannot capture promise-to-pay dates or resolve blockers in real time on the call
Best for: Finance teams and advisory firms using Xero or QuickBooks that want automated phone, SMS, and email reminder sequences without manual chasing.
The right payment and invoice reminder call solution for an investment advisory firm depends on where the billing problem actually lives. Firms whose central use case is recurring planning-fee billing will find AdvicePay's specialist focus a strong match. Teams that want voice follow-up with promise-to-pay capture and CRM-ready outcomes should look at InvoicifyAI's Invoice Reminder Agent. Firms that want systematic coverage of their entire overdue book before accounts reach formal collections can evaluate Sono. And practices already running Xero or QuickBooks that want multi-channel reminder automation including scheduled phone calls will find Chaser a practical fit. For advisory firms that want a managed, compliance-forward service run against approved client lists, without building an in-house call center, My AI Call Center offers a different model: campaigns scoped around one clear goal, quoted in full before launch, and run by a team that checks list source and consent records before any campaign starts. Calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign and no per-seat charges or platform bill. The first campaign review is free, so you know the full number before approving launch. If your firm is tired of chasing retainer payments by email and wants a structured phone reminder program without adding headcount, plan a campaign review at myaicallcenter.app and see whether a managed reminder calling campaign fits your billing workflow.
Frequently asked questions
Why do investment advisory firms need phone-based payment reminders instead of just email?
Email reminders solve the easiest cases: the client who simply forgot, or the invoice that landed in a busy inbox. The harder cases, like the client whose invoice is stuck in internal approval, the household that never received the planning-fee invoice, or the retainer that needs a specific commitment to a payment date, usually need a phone conversation. A short, structured call confirms the invoice reached the right person, surfaces the real blocker, and captures a promise-to-pay date someone actually commits to. For RIAs running on thin margins and recurring retainer billing, that conversation is often the difference between a 30-day delay and an on-time payment.
What compliance considerations apply to AI-generated reminder calls for advisory firms?
The FCC has confirmed that AI-generated voices are 'artificial' under the Telephone Consumer Protection Act, which means prior express consent is required before placing an AI-assisted reminder call. State-specific rules add quiet hours, day-of-week restrictions, and registration requirements that vary by jurisdiction. Reputable providers disclose the AI nature of the call on every attempt, honor keyword opt-outs like STOP and REVOKE immediately, respect Do Not Call requests across all campaigns, and carry opt-outs into client DNC records. Advisory firms should obtain their own legal guidance before launching any reminder program, since campaign requirements vary by location, industry, contact type, and consent status.
How does My AI Call Center handle list quality and consent before calling?
List discipline is a core part of the service. Before any campaign launches, My AI Call Center reviews list source and consent records. Bought lists without clear permission records are flagged and, in most cases, declined. The team tells you plainly if a list will not support the campaign, before you spend anything. This protects the firm's compliance posture and reduces the risk of calling contacts who never agreed to receive reminder calls from the firm. Approved, permissioned, or reviewed lists are the only lists that go into production.
What does a Payment & Invoice Reminder Calls campaign actually include?
A Payment & Invoice Reminder Calls campaign places calls a few days before an invoice due date, with structured follow-up if the payment remains unpaid. Every campaign is scoped around one clear goal, quoted in full before launch, and run only against approved, permissioned, or reviewed contact lists. Before any calls go out, the firm approves the script, disclosure language, opt-out handling, and escalation path. Calls run in approved windows, outcomes are monitored in real time, and a named outcome report is delivered with disposition codes (confirmed, opted out, no answer), per-call notes, and routed follow-ups handed back to the firm's team.
How is My AI Call Center priced, and what does the full number include?
Calling starts at 9¢ per connected minute, tiered by volume, with the rate agreed before launch and locked for the campaign. Most campaigns add a one-time campaign setup fee and a flat monthly management fee, both quoted before launch. There are no per-seat charges, no platform bill, and no minimums you did not choose. The first campaign review is free, so the full number is known before approving launch. Outcomes route back into the CRM and scheduling tools the firm already runs, and reporting reflects exactly what happened on every call, with no invented numbers.
Can these reminder call solutions integrate with existing CRM and accounting systems?
Integration depth varies by provider. My AI Call Center routes outcomes back into the CRM and scheduling tools the firm already runs, with hot follow-ups transferring live or landing in the CRM. AdvicePay offers an API for integrations with advisor tech stacks. InvoicifyAI logs outcomes to invoice and CRM records. Sono connects to billing, ERP, or AR platforms and writes outcomes back to the system. Chaser integrates with Xero and QuickBooks Online. Advisory firms should confirm exactly which fields sync, how exceptions route, and whether the integration is real-time or batch before signing.
What results should an investment advisory firm expect from a structured reminder calling program?
Results depend on list quality, invoice terms, and how the firm follows up on routed outcomes. Industry research cited across the reminder software category suggests that roughly 65% of customers pay on time when they receive a timely reminder, and that a phone call remains one of the few channels that can confirm an invoice arrived, surface a dispute, and capture a specific promise-to-pay date in one conversation. The most useful measure for an advisory firm is not raw collection rate but the reduction in days sales outstanding on retainer and planning-fee invoices, and the number of promise-to-pay commitments that convert to payment within the agreed window.
