Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Late planning fees are a quiet problem in advisory work. AUM fees sweep from custodial accounts on their own schedule, but flat fees, retainers, and hourly engagements depend on a client actually doing something: approving the invoice, clicking a payment link, or mailing a check. When that doesn't happen, someone at the firm has to follow up, and that someone is usually an advisor or paraplanner whose time is better spent on planning. For 2026, firms are increasingly splitting the work: the billing system owns the receivable, and a reminder layer handles the chasing. This listicle compares five options that can carry payment and invoice reminder calls for investment advisory firms, from done-for-you managed calling to advisor-specific billing platforms with automated reminders. We looked at what each provider actually publishes: features, pricing, compliance posture, and fit for advisory fee structures. Whether you bill a handful of retainers or hundreds of recurring planning fees, one of these should match your workflow.

#1 My AI Call Center — Calling starts at 9¢ 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. The first campaign review is free.

My AI Call Center is a done-for-you managed outbound calling service, owned and operated by AIQ Labs, that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. For an advisory firm, the Payment & Invoice Reminder Calls campaign is scoped around one clear goal: get more planning fees paid on time without pulling advisors and operations staff away from client work. Calls are placed a few days before an invoice due date, with structured follow-up if the payment remains unpaid, and every campaign is quoted in full before launch. You don't buy software you have to learn. You buy campaigns that the team runs for you, and outcomes route back into the CRM and scheduling tools you already run, so a confirmed payment date or a follow-up request lands where your team will actually see it. The differentiator is list discipline. 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 the list will not support the campaign, before you spend anything. That matters in advisory work, where your client list is a relationship asset and a compliance obligation at the same time. Compliance is built into every call: 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 (STOP and REVOKE) are honored immediately, and state-specific quiet hours and calling rules are respected. Opt-out and DNC logs come back with every campaign, and client data is never shared, sold, or used to train shared models. You get a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and follow-up requests routed to your team. No invented numbers, just what actually happened.

Best for: Investment advisory and financial planning firms (typically 1–200+ staff) that want managed, compliance-forward reminder calls against approved client lists without building an in-house collections function.

#2 AdvicePay — Contact for pricing (quote-based, scoped to firm and client volume, plus payment fees).

AdvicePay is the most directly aligned billing platform for firms charging financial-planning fees through invoices or subscriptions. It was created specifically to handle fee-for-service planning payments, both one-time and recurring retainers, because general payment processors often didn't meet state regulators' expectations around custody avoidance and client notifications, according to the Kitces review that introduced the platform. For an advisory firm, that category fit is the main draw: recurring retainer billing, invoice tracking, and a follow-up process for missed payments all live in one place, designed with advisory compliance in mind rather than bolted onto generic invoicing software. The reminder workflow is built around the receivable itself. When a client misses a retainer payment, the platform supports a structured follow-up process instead of a firm staff member manually emailing and calling. Buyers should still verify the details that matter in practice: approval roles, client entities, failed payment handling, refunds, partial adjustments, exports, and which systems receive status updates. AdvicePay is strongest when planning-fee billing is the central use case. If the receivable is ordinary firm accounting unrelated to planning engagements, or if your accounting platform already handles the complete controlled flow, a general invoicing tool may be the simpler choice.

Best for: Fee-for-service and retainer-based financial planning firms that want billing and payment reminders built specifically for advisory compliance.

#3 Anchor — No subscriptions or hidden fees; $5 per payment received, according to their website.

Anchor takes a different angle on the reminder problem: prevent the late payment rather than chase it. According to their website, Anchor turns signed planning agreements into collected revenue by capturing the client's payment method at signing, so flat fees and retainers get billed and charged automatically on schedule. Recurring invoices generate on their own, and reminders keep collections out of client meetings. The platform reports powering 1,500+ US financial advisors and cites a 90% reduction in late payments among users, a vendor-claimed figure worth treating as directional rather than audited. The workflow is straightforward: send a branded agreement with the fee defined, capture payment at signing, automate invoicing on schedule, charge ACH or credit card on the due date, and reconcile everything automatically to QuickBooks or Xero. That last step is a real time-saver for firms that currently match payments to invoices by hand. Anchor also supports configurable processing fees, so firms can pass standard credit card costs to clients instead of absorbing them. The tradeoff is structural: if a client's payment method fails or a fee needs a conversation, automated charging only goes so far, and someone still has to make the call. Firms with heavy exception volume may want a reminder-calling layer alongside it.

Best for: Advisory firms that want flat fees and retainers to collect themselves through payment capture at signing, with reminders as a backstop rather than the main mechanism.

#4 InvoicifyAI — Invoice Reminder Agent included in the Pro plan at $149 USD/month (400 shared AI voice minutes, then $0.35/min overage), according to their website. Business plan available above that.

InvoicifyAI's Invoice Reminder Agent is built for service businesses whose real problem isn't sending the first reminder, it's getting a response after the emails have been ignored. 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 an advisory firm, that maps to the common retainer situation: the client says they never saw the invoice, or the payment is waiting on a spouse's sign-off, and a two-minute call resolves what three emails couldn't. The platform describes a four-touch cadence: a friendly Day 1 reminder, a Day 7 follow-up requesting a firm timeline, a Day 14 escalation that surfaces blockers, and a Day 30 final notice that routes unresolved accounts to your team. Each call logs a promise-to-pay date, blocker, or voicemail outcome, and follow-up is auto-scheduled if payment doesn't arrive by the committed date. The agent shares payment instructions already stored on the invoice and stops when the invoice is paid. It's a self-serve software product rather than a managed service, so someone at the firm owns setup, monitoring, and exception handling. Pricing is published on plan tiers: the Invoice Reminder Agent is included in the Pro plan at $149 USD per month with 400 shared AI voice minutes, and the Business plan above it.

Best for: Small advisory and planning firms that want self-serve AI voice follow-up on overdue invoices, with promise dates and blockers logged into their records.

#5 Paidnice — Contact for pricing (subscription-based, with plans quoted by invoice volume).

Paidnice is an accounts receivable automation platform for Xero and QuickBooks users, and its strength is making the reminder call the exception rather than the rule. According to their website, Paidnice runs reminders, late fees, and statements automatically for Xero and QuickBooks businesses, and customers get 8 in 10 invoices paid within the first 60 days of using the platform, a vendor-claimed figure. The logic is sound: if the automated email and SMS sequence, late fee, and statement do most of the collection work, your team only picks up the phone for the accounts that genuinely need a conversation. To support that conversation, Paidnice publishes a set of collection call scripts covering the situations that come up most: the first overdue call, a disputed invoice, an invoice that never arrived, internal approval delays, an absent decision-maker, a payment plan negotiation, and a repeat late payer. The recommended structure is practical: open by naming the invoice number, amount, and due date, listen to what's holding payment up, ask for a specific date, and confirm the commitment in writing the same day. For an advisory firm already invoicing through Xero or QuickBooks, Paidnice adds AR visibility, payment plans, and accounting-system writeback without moving the ledger. The limitation is channel depth: it's email-and-SMS-first with human calls as the fallback, so firms wanting automated voice reminders need to pair it with a calling layer.

Best for: Advisory firms that invoice through Xero or QuickBooks and want automated reminder sequences and late fees, with manual calls reserved for stuck accounts.

The right choice depends on where your late-fee problem actually lives. If invoices are going out correctly and clients just aren't acting on them, a reminder-calling layer like My AI Call Center's managed Payment & Invoice Reminder Calls campaign does the follow-up work for you, against approved client lists, with consent reviewed before launch and outcomes routed back into your CRM. Calling starts at 9¢ per connected minute with the rate locked for the campaign, and the first campaign review is free, so you know the full number before anything launches. If the problem is upstream, AdvicePay or Anchor can fix the billing structure itself so fewer invoices go late in the first place. InvoicifyAI suits firms that want self-serve AI voice follow-up, and Paidnice fits teams already running Xero or QuickBooks that want automated sequences with manual calls as the exception. Whatever you pick, test it against a draft invoice, an overdue one, a partial payment, and a dispute before go-live.
