Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Fee-for-service advisory work has a collections problem that AUM firms never had to think about. When you bill planning retainers, hourly fees, or project fees directly to clients, the invoice goes out, and then it sits. Someone has to follow up, and that someone is usually an advisor or paraplanner who would rather be doing planning than asking a client why the retainer hasn't been paid. Email reminders handle the easy cases, but the harder ones need a conversation: the invoice went to the wrong household member, the client is waiting on a spouse, or there's a question about the engagement scope. A structured reminder call catches those issues in two minutes instead of two weeks of email tag. The catch for advisory firms is that this is a regulated industry. You're calling clients about money, so consent records, disclosure, and supervisory documentation all matter. This 2026 guide compares five options, from managed calling services that run compliant campaigns for you, to advisor-specific billing platforms where reminders are part of a larger fee collection workflow. We've stuck to what each provider actually publishes, and where pricing isn't public, we say so.

#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 an operating base in Austin, Texas. You don't buy software and figure it out. You buy campaigns that the team runs for you, each scoped around one clear goal and quoted in full before anything launches. 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, so retainer and planning-fee balances get caught before they age into awkward territory. The differentiator for a regulated industry 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 won't support the campaign, before you spend anything. For an advisory firm calling its own clients, that review is a real safeguard: you know the consent posture of every number before the dialer touches it. Compliance is built into every call too. 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 are delivered with every campaign, and client data is never shared, sold, or used to train shared models. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path, which means your compliance officer sees exactly what will be said before it's said. After the campaign, you get a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and follow-up requests routed back into the CRM and scheduling tools you already run. Hot escalations transfer to your team live or land in your CRM. Pricing is transparent: 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. No per-seat charges, no platform bill, no minimums you didn't choose. The first campaign review is free, so you know the full number before approving anything. One note: the firm's own disclaimer says campaign requirements vary by location, industry, and consent status, and clients are responsible for getting appropriate legal guidance before launch. That's honest, and it's the right posture for advisory work.

Best for: Investment advisory and financial planning firms (1–200+ staff) billing retainers or planning fees that want managed, compliance-forward reminder calls against their own approved client lists, without building an internal collections function.

#2 AdvicePay — Contact for pricing

AdvicePay is the most category-specific option on this list. It was started in 2016 by Alan Moore and Michael Kitces, two well-known figures in financial planning, to solve exactly the problem fee-for-service advisors face: collecting planning fees in a way that satisfies state regulators on custody and client notification. According to its Schwab Advisor Services provider listing, AdvicePay offers recurring and subscription billing options built for advisors offering fee-for-service advice, with in-house developers who handle regulatory issues as they come up. A 2026 buyer's guide from US Tech Automations scored AdvicePay as the strongest candidate for planning-fee workflows, giving it top marks for invoice ownership, reminder control, and advisor context. The platform handles invoicing, recurring retainer billing, and payment collection from client bank accounts or cards, so reminders exist inside a system that already owns the receivable. That structure matters for advisory firms: the reminder goes out from the same platform that holds the approved billing record, which reduces the wrong-recipient errors that generic invoicing tools can produce when the accounting customer doesn't match the CRM household. The US Tech Automations guide advises buyers to verify approval roles, client entities, failed payment handling, refunds, and exports before committing, which is sound advice for any regulated purchase. AdvicePay doesn't publish pricing; you contact the vendor for a quote based on firm and client scope. It's the right fit when planning-fee billing is your central use case. If your receivables are ordinary firm accounting unrelated to planning engagements, a general accounting platform may cover the flow more simply.

Best for: Fee-for-service financial planning firms and RIAs whose central collections problem is recurring planning retainers and subscription fees.

#3 InvoicifyAI Invoice Reminder Agent — Included in the Pro plan at $149 USD/month (400 shared AI voice minutes, then $0.35/min overage); 7-day free trial advertised.

InvoicifyAI's Invoice Reminder Agent goes beyond automated email reminders by actually calling customers about overdue invoices. According to their website, the agent 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 chasing an unpaid planning retainer, that conversation captures the things email can't: the client never saw the invoice, the fee needs a spouse's sign-off, or there's a question about the engagement that should go to the advisor, not the billing system. The platform focuses on response-oriented follow-up. A typical cadence described on their site runs Day 1 reminder, Day 7 follow-up, Day 14 escalation, and Day 30 final notice, with follow-up auto-scheduled if a promised payment doesn't arrive. InvoicifyAI describes this as CRM-ready outcome logging, meaning call results connect to customer history rather than getting lost in a spreadsheet. The agent also handles voicemail drops, retry scheduling, and shares payment instructions stored on the invoice, and it escalates exceptions to your team when a person should step in. That handoff structure suits advisory work, where a dispute or relationship-sensitive conversation should always route to a human. Pricing is published: the Invoice Reminder Agent is included in the Pro plan at $149 USD/month, which also bundles an AI receptionist, CRM suite, and 400 shared AI voice minutes (with $0.35/min overage). A 7-day free trial is advertised. Note that voice minutes are shared across the plan's features and capped, so heavy calling volume will trigger overage charges. It's a self-serve software product, so your firm owns the compliance configuration, consent posture, and calling-window setup.

Best for: Service businesses, including advisory and planning firms, that want self-serve voice follow-up on overdue invoices with payment commitments logged to the customer record.

#4 Anchor — $5 per payment received; no subscription fees.

Anchor takes a different approach to the collections problem: prevent the reminder from being needed at all. According to their website, Anchor captures the client's payment method at the moment they sign the planning agreement, then generates invoices automatically on schedule and charges flat fees, retainers, or one-time payments via ACH or credit card on the due date. The firm positions this as turning signed planning agreements into collected revenue, and reports powering 1,500+ US financial advisors. The reminder piece exists, but it's a backstop rather than the main mechanism. Anchor's site describes recurring invoicing with reminders that keep collections out of client meetings, plus a real-time dashboard tracking live revenue, renewals, and outstanding invoices. The stronger play is structural: because payment is captured at signing, the firm says advisors see a 90% reduction in late payments and 15+ hours saved monthly on admin. Those are vendor-reported figures, so treat them as claims rather than audited results. Anchor also highlights configurable processing fees, so you can pass standard credit card costs to clients rather than absorbing them, and automatic reconciliation to QuickBooks or Xero. Pricing is unusually simple and public: $5 per payment received, with no subscriptions or subscription fees. Customer reviews quoted on their site praise the agreement templates and support. For advisory firms, the honest tradeoff is that Anchor minimizes reminder calls rather than excelling at them. If your fee model is a recurring retainer charged to a saved payment method, that prevention-first design may solve the problem before a call is ever needed. If you bill one-off project fees to clients who prefer to initiate payment themselves, you'll still need a follow-up channel.

Best for: Financial advisors billing flat fees, retainers, or hourly consultations who want payment captured at signing so most reminders never become necessary.

#5 BILL Accounts Receivable — Contact for pricing

BILL is the broadest platform on this list, an accounts payable and receivable automation suite used by over 500,000 businesses according to its website. For advisory firms, the relevant capability is BILL Accounts Receivable, which the US Tech Automations 2026 guide scored well for invoice ownership, reminder control, and cross-system fit, positioning it for AR workflow and collections. If your firm's finance function already runs on BILL for payables, adding receivables keeps invoice delivery, electronic payments, and follow-up workflow in one back-office platform. BILL's wealth management page shows the firm also serves single and multi-family offices, RIAs, and wealth management firms with a bill pay product built for ultra-high-net-worth client needs: multi-entity support, detailed approval rules, and security standards including AICPA SOC 2 and PCI compliance. That's a different product from AR reminders, but it signals the company's experience with regulated financial services clients and sensitive data. The US Tech Automations guide offers the right caution for advisory buyers: confirm what accounting platform is authoritative, and check how disputes or changes pause notices before relying on the reminder flow. BILL should not be used to recreate portfolio fee calculations or replace the advisor CRM. Pricing isn't published for the AR product on the pages we reviewed, so contact the vendor. BILL is a fit when finance wants receivables workflow inside a broader back-office platform, and when invoice volume justifies the implementation depth. A small firm with a handful of planning retainers will likely find a lighter tool simpler.

Best for: Advisory and wealth management firms that want receivables workflow as part of a broader back-office AP/AR platform, especially those already using BILL.

The right choice depends on where your collections problem actually lives. If unpaid planning retainers are piling up and your team dreads the follow-up calls, a managed reminder calling service like My AI Call Center takes that work off your plate entirely: campaigns run only against your approved client list, consent records are checked before launch, the script gets your approval before anything runs, and outcomes land back in your CRM with disposition codes. Calling starts at 9¢ per connected minute with the rate locked, and the first campaign review is free. If your problem is structural rather than behavioral, Anchor's capture-payment-at-signing model or AdvicePay's advisor-specific billing may prevent the reminder from being needed. InvoicifyAI adds self-serve voice follow-up on top of existing invoicing, and BILL fits firms wanting receivables inside a full back-office suite. Whatever you pick, verify the compliance fit for your firm before launch: consent posture, disclosure, and supervisory documentation are your responsibility in a regulated industry, and any vendor who tells you otherwise is worth walking away from.
