Best Payment & Invoice Reminder Calls for Investment Advisory Firms

Fee-for-service planning has a collections problem that AUM billing never had. When you bill retainers or flat fees by invoice, somebody has to chase the ones that go unpaid, and for most advisory firms that somebody is an advisor or operations staffer making awkward calls between client meetings. Research from BILL suggests 40% of small and midsize businesses feel direct negative impacts from late payments, and Upflow reports roughly 70% of invoices in the US get paid late. Email reminders help with the easy cases. The hard cases, a client who never saw the invoice, a payment stuck in internal approval, a household disputing a charge, need an actual conversation. For 2026, a small group of platforms can place those reminder calls for you, or remove the need for them entirely. This listicle compares five options that fit investment advisory firms, from done-for-you managed calling to advisor-specific billing systems. We looked at what each one actually does, what it costs, and where it falls short.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; rate locked for the campaign. Most campaigns add a one-time setup and a flat monthly management fee, quoted before launch. 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, its Payment & Invoice Reminder Calls campaign is built around one clear goal: reduce late planning-fee and retainer payments without pulling your advisors or operations staff off client work. Calls go out a few days before an invoice due date, with structured follow-up if the payment stays unpaid. You don't buy software and learn it. You buy campaigns that the team runs for you, with the whole campaign quoted before it launches. The differentiator is list discipline, which matters a lot in a regulated industry. Before any campaign launches, My AI Call Center reviews list source and consent records. Bought lists without clear permission records get flagged and, in most cases, declined. The team tells you plainly if the list won't support the campaign, before you spend anything. That's a meaningful safeguard for an RIA, where calling the wrong household or working from a list without documented consent creates real compliance exposure. 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, and recipients can ask for a human or opt out. Keyword opt-outs like STOP and REVOKE are honored immediately, state-specific quiet hours are respected, and DNC requests are carried into your client records. Reporting is honest by design. The company states it will never invent metrics, testimonials, or ratings, and every campaign ends with a named outcome report: disposition codes (confirmed, qualified, opted out, no answer), per-call notes, and follow-up requests routed back into the CRM and scheduling tools you already run. Hot items can transfer to your team live or land in your CRM. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path. Pricing 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. There are no per-seat charges and no minimums you didn't choose. The first campaign review is free, so you know the full number before approving anything.

Best for: Investment advisory firms (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

AdvicePay is the specialist candidate for recurring financial-planning fees. It was built specifically for fee-for-service advisors, launched originally to solve the billing and compliance problems that generic payment processors like PayPal couldn't handle for RIAs. According to Kitces.com, it was created to facilitate one-time and especially recurring retainer fees in a manner designed to avoid custody issues that concern state regulators, and to integrate with the systems financial planners already use. For an advisory firm, the appeal is category fit. AdvicePay handles the full planning-fee billing workflow, so reminders become part of a system that owns the receivable rather than a bolt-on chasing tool. A 2026 comparison from US Tech Automations scored it highly on invoice ownership, reminder control, and advisor context, positioning it as the strongest choice when planning-fee billing is the central use case. The same analysis advises buyers to verify approval roles, client entities, failed payments, refunds, and export behavior before committing, and notes you should skip it when your accounting platform already handles the complete controlled flow. AdvicePay is not a voice-calling service; its reminders live in the billing workflow itself, reducing the number of invoices that ever need a phone call.

Best for: Fee-for-service and retainer-based advisory firms that want planning-fee billing and reminders handled by a purpose-built advisor platform.

#3 Anchor — $5 per payment received, no subscription fee, according to their website.

Anchor takes a different approach to the reminder problem: it tries to make reminders mostly unnecessary. According to their website, Anchor captures the client's payment method at the moment they sign the planning agreement, then charges flat fees, retainers, and one-time payments automatically on the due date. Invoices generate automatically from the signed agreement, and every payment and processing fee reconciles automatically to QuickBooks Online or Xero. The firm says it powers 1,500+ US financial advisors and reports a 90% reduction in late payments and 15+ hours saved monthly on admin. Anchor supports ACH and credit card payments, lets advisors pass standard card processing fees to clients, and handles renewals without a new agreement. It also includes recurring invoicing with reminders, so collections work stays out of client meetings. Anchor's own published figure is $5 per payment received, with no subscription fee, which is unusually transparent for this category. The trade-off is the same as any auto-charge model: it works best when clients sign and store a payment method up front. For firms with legacy receivables or clients who resist card-on-file billing, you'll still need a follow-up channel for the exceptions.

Best for: Advisory firms that want to prevent overdue invoices by capturing payment at signing rather than chasing them afterward.

#4 InvoicifyAI — Pro plan at $149 USD/month including the Invoice Reminder Agent (400 shared AI voice minutes, $0.35/min overage); Starter at $99/month without the agent.

InvoicifyAI's Invoice Reminder Agent is the closest software alternative to a managed reminder-call service. 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. Their published cadence is a four-touch sequence: a Day 1 friendly reminder call, a Day 7 follow-up seeking a commitment, a Day 14 escalation, and a Day 30 final notice that routes unresolved accounts to your team. For an advisory firm, the value is in the exception handling. When a client says they never received the invoice, or a payment is stuck waiting on a spouse's approval, the agent captures the blocker and logs it rather than just leaving another voicemail. The platform stops when an invoice is paid and escalates disputes to staff. It's self-serve software rather than a managed service, so your team owns setup, calling windows, and consent posture. Pricing is published: the Invoice Reminder Agent is included in the Pro plan at $149 USD per month (400 shared AI voice minutes, then $0.35/min overage) and in Business; the Starter plan is $99 per month but does not include the reminder agent.

Best for: Service businesses and small firms that want self-serve AI voice follow-up on overdue invoices with promise and blocker logging.

#5 BILL Accounts Receivable — $49 per user per month, according to a 2026 G2 billing software review.

BILL fits firms whose receivables problem is broader than planning fees. According to their site, BILL supports invoice delivery, electronic payments, and receivables workflow in a back-office platform, and they market specifically to wealth management firms, RIAs, and family offices. Their own guidance on payment reminders is practical: send a nudge three to five days before the due date, on the due date, one week late, two weeks late, one month late, and a final notice, escalating tone gradually while staying professional. They also note that when emails go unheeded, it may be time to switch mediums and call the client directly. BILL's strengths are operational. You can filter invoices by status, set automated reminders, and manage approvals and user roles, which matters for firms with supervisory and books-and-records obligations. A 2026 G2 review lists BILL AP/AR at $49 per user per month. The US Tech Automations comparison positions it well for AR workflow and collections, while cautioning that it shouldn't replace your advisor CRM or recreate portfolio fee calculations. For an advisory firm, it's best understood as the receivables layer for general firm invoicing, with reminder emails automated and phone follow-up still done by your staff.

Best for: Firms that want AR workflow automation and automated email reminders inside a broader back-office platform.

The right choice depends on where your invoices actually get stuck. If your firm bills planning fees by invoice and the problem is clients not responding to email, reminder calls are the fix, and My AI Call Center is the strongest option here because the campaign is run for you, quoted before launch, and built on approved, permissioned lists with consent records checked up front. That combination of managed execution and list discipline is rare, and it matters more in a regulated industry like investment advisory. If your problem is structural, Anchor or AdvicePay can prevent overdue invoices by capturing payment at signing or billing retainers automatically. InvoicifyAI suits teams that want self-serve AI voice follow-up with promise-to-pay logging, and BILL handles broader AR operations with automated email reminders. Whatever you choose, verify consent posture and calling rules before launch; the FCC treats AI voices as artificial under the TCPA, so prior express consent isn't optional.
