Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Fee-for-service advisory work has a collections problem that the AUM world never had to think about. When a planning retainer or quarterly fee invoice goes unpaid, nobody sweeps it from a custodial account. Someone at your firm has to chase it, and that someone is usually an advisor or paraplanner whose time is worth far more than the awkward phone call they're making. Email reminders help, but a 2026 reality check from collections practitioners is blunt: roughly 70% of invoices in the US are paid late, and the accounts that ignore email are the ones that need a live conversation. A structured reminder call, placed a few days before the due date with polite follow-up if the invoice stays unpaid, confirms the invoice arrived, surfaces whatever is blocking payment, and captures a promise-to-pay date the client actually commits to. In this 2026 guide, we compare five options that help investment advisory firms run payment reminder calls professionally, with compliance awareness and outcomes that route back into the systems your firm already runs.

#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 and based in Halifax, Nova Scotia with a US operating base in Austin, Texas. It runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only, never indiscriminate cold calling. For an advisory firm, that distinction matters more than almost anything else. Your client list is a consented, high-value list, and the team treats it that way: 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 a list won't support the campaign, before you spend anything. The Payment & Invoice Reminder Calls campaign is scoped around one clear goal: reduce late payments on planning fees and retainers without pulling your advisors off client work. Calls go out a few days before an invoice due date, with structured follow-up if the payment remains unpaid. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path. Compliance is built in: AI-generated voices are treated as artificial voices under the TCPA, prior express consent is required, AI disclosure is provided on every call, keyword opt-outs like STOP and REVOKE are honored immediately, and state-specific quiet hours and calling rules are respected. Client data is never shared, sold, or used to train shared models. The differentiator for a regulated firm is that this is a managed service, not software you have to learn. You buy campaigns that the team runs for you. 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 follow-up requests handed to your team. Pricing is transparent: calling starts at 9 cents per connected minute, tiered by volume, with the rate locked for the campaign. Most campaigns add a one-time 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.

Best for: Investment advisory firms and multi-location financial services businesses (1–200+ staff) that want a managed, compliance-first reminder calling service against approved client lists, without building an internal collections team or learning new software.

#2 InvoicifyAI Invoice Reminder Agent — Included in the Pro plan at $149 USD/month according to their website, with a 7-day free trial advertised. Voice minutes are shared and capped per plan with overage charges.

According to their website, InvoicifyAI's Invoice Reminder Agent goes beyond automated email reminders by calling customers about overdue invoices, confirming whether the invoice was received, asking whether anything is blocking payment, capturing promise-to-pay dates, and logging outcomes back into the customer record. For an advisory firm billing quarterly planning retainers, that blocker-capture step is the useful part: a call can surface a missing purchase order, a disputed amount, or a client waiting on their own accountant, and record the commitment so the next step is clear. The platform describes a typical cadence of Day 1 reminder, Day 7 follow-up, Day 14 escalation, and Day 30 final notice, with auto-scheduled follow-up if a promised payment does not arrive. It positions this as CRM-ready outcome logging, meaning call results connect to customer history rather than getting lost in a spreadsheet. The agent shares payment instructions already stored on the invoice, stops when an invoice is paid, and escalates exceptions like disputes to your team. Voice minutes are shared and capped per plan, with overage charges beyond the included allowance. It is a self-serve software layer rather than a managed service, so your firm owns the setup and monitoring.

Best for: Service businesses and professional firms, including advisory practices, that need polite voice follow-up on overdue invoices with payment commitment capture and CRM-ready outcomes.

#3 AdvicePay — Contact for pricing (quoted by firm and client scope).

AdvicePay is the specialist candidate for recurring financial-planning fees. Started in 2016 by Alan Moore and Michael Kitces, it was built specifically to give fee-for-service financial advisors a compliant way to collect planning fees, including recurring retainers, without the custody problems that come from using generic payment processors. According to the Kitces review that introduced the platform, AdvicePay exists because most existing payment processors either did not meet state regulator expectations around custody and client notifications, prohibited financial advisors from using them at all, or had no intention of integrating with advisor systems. AdvicePay offers recurring and subscription billing options for advisors offering fee-for-service advice, with in-house developers who address regulatory issues as they come up, according to its Schwab Advisor Services provider listing. For a firm whose reminder problem is concentrated in planning retainers and subscription fees, that category fit is the main draw. The reminder workflow is largely billing-platform-driven rather than a voice-calling program, so firms that need live reminder calls on stuck invoices would typically pair a billing platform like this with a separate calling service. Pricing is not published; the vendor is quoted by firm and client scope.

Best for: Fee-for-service financial planning firms whose reminder problem is concentrated in recurring planning retainers and subscription fees, and who want billing handled inside an advisor-specific, compliance-aware platform.

#4 Anchor — $5 per payment received, with no subscriptions or monthly fees, according to their website.

Anchor is financial advisor billing software that turns signed planning agreements into collected revenue by capturing payment at signing, so flat fees and retainers collect themselves. According to their website, the platform powers 1,500+ US financial advisors and handles flat fees, retainers, and hourly consultations from one branded agreement, with ACH transfer and credit card payment options, configurable processing fees that can be passed to clients, and recurring invoicing with reminders that keep collections out of client meetings. The Anchor approach is prevention rather than chase: capture the client's payment method the moment they sign, then generate invoices automatically on schedule and charge the due date without a new agreement for renewals. Payments auto-reconcile to QuickBooks or Xero through native integrations, and the firm reports a 90% reduction in late payments and 15+ hours saved monthly on admin, according to their website. Pricing is simple and published: you pay $5 per payment received, with no subscriptions and no monthly fees. The limitation for a firm with an aging receivables problem is that Anchor is designed to stop invoices from going overdue in the first place; it does not place reminder calls to clients whose invoices are already stuck.

Best for: Advisory firms that want to prevent overdue planning fees by capturing payment at signing, rather than chasing invoices after they go unpaid.

#5 Paidnice — Contact for pricing.

Paidnice focuses on accounts receivable automation for Xero and QuickBooks users. According to their website, it runs the reminders, late fees, and statements automatically, and the company reports that customers get 8 in 10 invoices paid within the first 60 days of using the platform. For an advisory firm whose bookkeeping already lives in Xero or QuickBooks, that accounting-system writeback is the practical draw: reminders, statements, and payment plans stay connected to the ledger rather than living in a separate tool. Paidnice also publishes genuinely useful collections guidance, including an eight-script collection call framework that advisory operations staff can adapt for client calls: open with the invoice number and amount, listen for what is holding payment up, ask for a specific date, and confirm the commitment in writing the same day. The platform itself is reminder and fee automation rather than a calling service, so the phone work it prepares you for still has to be done by your team or by a service like My AI Call Center. The watch-out is scope: if your main problem is a client ignoring emails and needing a live conversation, make sure the workflow covers the channel you actually need.

Best for: Advisory and finance teams using Xero or QuickBooks that want AR automation, statements, and reminder sequences with accounting-system writeback.

The right choice depends on where your firm's money is getting stuck. If planning retainers go unpaid because clients never set up payment in the first place, Anchor's capture-payment-at-signing model or AdvicePay's advisor-specific billing stops the problem before it starts. If your invoices are already aging and email reminders are being ignored, you need the phone: InvoicifyAI offers self-serve voice follow-up with promise-to-pay capture, and Paidnice gives Xero and QuickBooks firms the reminder and fee automation that makes calls the exception rather than the rule. If you want the calls run for you, against your approved client list, with consent checked and compliance built into every call, My AI Call Center's Payment & Invoice Reminder Calls campaign is the managed option. Calling starts at 9 cents per connected minute, the rate is locked for the campaign, and the full number is known before you approve launch. The first campaign review is free, and nothing launches until you approve the script and escalation path. Plan your campaign at myaicallcenter.app/campaigns, or reach the team at [email protected].
