Fee-for-service planning has changed how advisory firms get paid, and it has also changed how they get paid late. Unlike AUM fees swept automatically from custodial accounts, planning retainers and one-time engagement fees depend on invoices that clients actually open, approve, and pay. When an invoice sits unpaid, someone on your team has to chase it, and that someone is usually an advisor or operations lead who has better things to do than leave voicemails. Phone calls work where email stalls because a live conversation confirms the invoice arrived, surfaces disputes or missing approvals on the spot, and secures a specific payment date. The challenge for advisory firms is doing this consistently, professionally, and within compliance boundaries, since client communications in this industry carry extra scrutiny. This guide compares five solutions for payment and invoice reminder calls in 2026, from done-for-you managed calling services to advisory-specific billing platforms and AR automation tools. We looked at real features, published pricing, compliance posture, and fit for firms that bill planning fees, retainers, or subscription-style engagements.
#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. 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, based in Halifax, Nova Scotia with an operating base in Austin, Texas. It is not software you have to learn, staff, or monitor. You buy campaigns that the team runs for you, each built 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 and follows up with structured calls if the payment remains unpaid. That maps directly onto how firms chase planning retainers, engagement fees, and subscription invoices that fall outside the AUM sweep. What genuinely separates My AI Call Center is list discipline and compliance-forward process. 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. AI-generated voices are treated as artificial voices under the TCPA, so 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. 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 named disposition codes (confirmed, opted out, no answer), per-call notes, and follow-up requests delivered to your team. Hot leads can transfer to your staff live or land in your CRM. The company's no-invented-numbers policy means you only see what actually happened on every call. Pricing starts at 9 cents per connected minute, tiered by volume, with the rate locked for the campaign and never moved mid-run.
Pros
- Done-for-you managed service with no per-seat charges, no platform bill, and no minimums you did not choose
- Strict list and consent review before launch protects the firm's compliance posture
- Full pricing known before approving launch, with the rate locked for the campaign
- Outcome reports with disposition codes route directly into existing CRM and scheduling tools
- Free first campaign review
Cons
- Not self-serve software; campaigns are quoted and run by the provider, which may not suit teams wanting instant DIY control
- Campaign requirements vary by location, industry, contact type, and consent status; clients are responsible for obtaining appropriate legal guidance before launch
- It handles the calling campaigns, not invoicing or payment processing itself
Best for: Investment advisory firms (typically 1 to 200+ staff) that want managed, compliance-forward reminder calls against approved client lists without building an in-house call center or buying another software seat.
#2 AdvicePay — Contact for pricing. Smith.ai reported a $10 per month starting point for independent advisors, but US Tech Automations' July 2026 check listed AdvicePay as quote-based with firm/client scope, so confirm current pricing with the vendor.
AdvicePay is the payment processing platform built specifically for fee-for-service financial planning, and it is the most directly aligned software candidate for advisory firms charging planning fees through invoices or subscriptions. According to a Kitces.com review, the platform was created to solve a compliance problem most general payment processors do not address: many mainstream processors do not meet state regulator expectations for avoiding custody and providing proper client notifications, and some prohibit financial advisors from using them at all. AdvicePay was designed to facilitate both one-time and recurring planning fees in a manner intended to be compliant for registered investment advisers. For reminder workflows, the platform supports recurring and automated billing, customizable invoices, approval features, and integrated payment processing, according to a Smith.ai roundup of billing solutions for financial planners. That means a failed or missed recurring payment can trigger follow-up within the billing system itself, keeping the reminder tied to the actual invoice record rather than a separate spreadsheet. Smith.ai lists automated payments and recurring invoices among its key capabilities, along with an API for integrations and premium data security. The trade-off is scope. AdvicePay is built for planning-fee billing, not general firm accounting. US Tech Automations' 2026 comparison scored it highest on invoice ownership, reminder control, and advisor context, but noted buyers should still verify approval roles, failed payment handling, refunds, partial adjustments, and exports. If your receivable is ordinary firm accounting unrelated to planning engagements, your accounting platform may already handle the flow.
Pros
- Category fit is unmatched; it is the specialist for planning-fee billing
- Compliance-first design aimed at RIA custody and notification rules
- Recurring billing automation reduces manual invoice chasing at the source
- Integrates payment processing directly with advisor workflows
Cons
- Quote-based pricing makes cost comparison harder
- Not suited to general firm receivables unrelated to planning engagements
- Reminder capability is tied to its billing flows; it is not a managed calling service
Best for: Advisory firms whose central billing use case is financial planning fees, hourly engagements, or recurring retainers that must stay outside custody.
#3 Chaser — Compact plan from A$399/month according to their website; a free trial is 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 days and times they choose. Each call is personalized to the recipient, and because calls are placed instantly on schedule, overdue invoices get followed up without waiting for a staff member to clear their to-do list. Chaser also supports a multi-channel approach, allowing firms to schedule phone call, SMS, and email reminders in one system so payment reminders get seen without bombarding clients. The platform integrates with accounting software such as Xero and QuickBooks Online, which makes it a practical fit for advisory firms that run their firm invoicing through those tools rather than a specialized billing platform. Chaser reports that over 10,000 users worldwide rely on the platform to get paid faster and protect cash flow. One honest caveat: Auto-call is not a conversational AI agent. It delivers pre-scripted messages rather than holding a two-way dialogue, so it cannot capture a promise-to-pay date or resolve a dispute mid-call the way a managed calling campaign or voice agent can. For advisory firms, that means it works well as a consistent first and second touch, but a disputed planning fee or a client waiting on internal approval still needs a human follow-up. Pricing is subscription-based depending on plan; the published Compact plan starts at A$399 per month according to their website, and a free trial is available.
Pros
- Automated phone calls remove the need for manual dialing
- Multi-channel scheduling keeps reminders coordinated across channels
- 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 and cannot capture commitments
- Pricing may be better suited to larger AR teams than small advisory practices
- No advisory-specific workflows or engagement/retainer context
Best for: Advisory firm finance and operations teams using Xero or QuickBooks Online that want automated phone, SMS, and email reminder sequences without manual chasing.
#4 InvoicifyAI Invoice Reminder Agent — Contact for pricing. One recent listing showed the Invoice Reminder Agent included in a Pro plan at $149 USD/month (400 shared AI voice minutes, then $0.35/min overage); confirm current plans with the vendor.
InvoicifyAI offers an Invoice Reminder Agent 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. That makes it a strong fit for advisory firms whose biggest problem is getting a real response after reminder emails have been ignored, for example a client who says the invoice never reached their household email or an engagement waiting on a family's internal decision. The agent follows a structured cadence, with a Day 1 friendly reminder call, a Day 7 follow-up with commitment, a Day 14 escalation call, and a Day 30 final notice, according to the company's site. Follow-up is 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. The agent also shares payment instructions already stored on the invoice, including payment links when available. Independent comparisons, including InvoicifyAI's own 2026 guide, position it as a response-oriented layer on top of existing invoicing rather than a full accounts receivable platform. For advisory firms, that framing is accurate: it handles the voice follow-up conversation, while your invoicing and payment records stay where they are. Pricing details have varied across sources; one recent listing showed the agent included in a Pro plan at $149 USD per month with 400 shared AI voice minutes and $0.35 per minute overage, so confirm current plans directly.
Pros
- Conversational AI captures payment promises and blockers, not just delivery
- Confirms invoice receipt and resolves misunderstandings in real time
- Full transcripts and outcome logging keep records clean
- Structured multi-touch cadence runs without staff intervention
Cons
- Pricing is not clearly published across sources; verify current plans
- Not a full AR or billing platform; invoicing stays in your existing system
- Consent, opt-out, and calling-window controls should be verified against your firm's compliance requirements before launch
Best for: Advisory firms and service businesses that want conversational voice follow-up on overdue invoices as a layer on top of their existing invoicing process.
#5 Paidnice — Essentials from A$99/month according to Truespeak's comparison (checked October 2026); confirm GST treatment and current plans with the vendor.
Paidnice focuses on accounts receivable automation for Xero and QuickBooks users, which covers a meaningful share of small and mid-sized advisory firms that run firm invoicing through those ledgers. According to Paidnice's own materials, the platform runs 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 product. That figure is a vendor claim, not an independently audited result, but it points to the platform's core thesis: most late payments resolve with consistent, well-timed reminders, and the phone call should be the exception rather than the routine. Where Paidnice becomes relevant for the reminder-call use case specifically is its escalation beyond email. Independent comparisons, including a Truespeak roundup of invoice reminder software checked in October 2026, list Paidnice as supporting email, SMS, and scheduled calls from your own domain or number, with published pricing for its Essentials plan starting at A$99 per month. The scheduled-call capability means an invoice that ignores email and SMS can still get a phone touch without a staff member dialing manually. The watch-out, noted in multiple comparisons, is scope and channel depth. Paidnice is finance-process oriented, built around statements, payment plans, and accounting-system writeback for Xero and QuickBooks teams. If your main problem is a client ignoring emails and needing a real conversation about a disputed planning fee, verify how the call workflow handles promise dates, disputes, and wrong-contact issues before committing. It is best treated as a disciplined AR automation layer, not a managed calling partner.
Pros
- Strong fit for firms already invoicing through Xero or QuickBooks
- Multi-channel escalation including scheduled calls
- Statements and payment plans reduce awkward one-off conversations
- Accounting writeback keeps reminder state tied to the ledger
Cons
- Performance figures (like 8 in 10 invoices paid in 60 days) are vendor claims
- Finance-process oriented; call handling of disputes and promise dates should be verified
- Requires Xero or QuickBooks; not a fit for firms billing through custodial or proprietary systems
Best for: Advisory firms and finance teams already running Xero or QuickBooks that want AR automation with statements, reminders, and an escalation path to scheduled calls.
Payment reminder calls are one of the few collections tactics that consistently outperform email for invoices that have gone quiet, and advisory firms feel the gap more than most because planning fees rarely ride on automatic AUM sweeps. The right choice depends on how your firm bills. If planning retainers and engagement fees are the core use case, AdvicePay is the specialist worth evaluating first. If your invoicing already lives in Xero or QuickBooks, Chaser and Paidnice add disciplined multi-channel reminders, and InvoicifyAI adds conversational voice follow-up on top. If you want the calls handled for you, with consent records reviewed before launch, AI disclosure on every call, and outcome reports that show exactly what happened, My AI Call Center is the strongest fit. The first campaign review is free, and the full price is known before you approve launch. Start by mapping one invoice segment that goes late most often, then plan a campaign around that single goal.
Frequently asked questions
Why do phone calls work better than email reminders for overdue advisory invoices?
A live call does three things email cannot. It confirms the invoice actually reached the right person at the household or business, it surfaces a dispute or missing approval on the spot instead of over days of email tag, and it secures a specific commitment: a date and an amount. Upflow's collection call research notes that verbal commitments, stated out loud by the client, are significantly more likely to be followed through. For advisory firms, where a disputed planning fee or an engagement awaiting a family decision is common, that real-time clarification matters.
Are AI-generated reminder calls compliant for advisory firms?
Compliance depends on consent and disclosure, and it varies by location and contact type. The FCC has confirmed that AI-generated voices are treated as artificial voices under the TCPA, which means prior express consent is required before placing them. My AI Call Center treats this as a design constraint: AI disclosure on every call, keyword opt-outs (STOP and REVOKE) honored immediately, DNC requests carried across campaigns, and state-specific quiet hours respected. Clients are responsible for obtaining appropriate legal guidance before launch, since requirements vary by industry, consent status, and jurisdiction.
How much do payment reminder calls cost?
It varies widely by model. My AI Call Center starts at 9 cents per connected minute, tiered by volume, with most campaigns adding a one-time setup fee and a flat monthly management fee, all quoted before launch. Chaser's published Compact plan starts at A$399 per month. Paidnice's Essentials plan starts at A$99 per month according to an October 2026 comparison. AdvicePay and InvoicifyAI require contacting the vendor for current pricing. Remember that payment processing fees, where applicable, are often a bigger cost driver than the reminder software itself.
Can these tools call my clients without me approving the message first?
With My AI Call Center, nothing launches until you approve the script, disclosure, opt-out handling, and escalation path. The campaign is scoped around one clear goal and quoted before launch. Software platforms like Chaser and Paidnice let your team configure templates and cadences yourself, which means your firm owns the wording and the schedule. Either way, the approved reminder language should match your firm's communication policies and any applicable regulatory guidance.
What happens when a client disputes the invoice during a reminder call?
This is where the difference between pre-scripted calls and conversational campaigns shows. A pre-scripted text-to-speech call, like Chaser's Auto-call, delivers a message but cannot resolve a dispute mid-call. Conversational approaches can capture the blocker and route it. My AI Call Center routes outcomes back into your CRM with disposition codes and per-call notes, so a disputed invoice lands with your team as a named follow-up request rather than disappearing into a voicemail log. Best practice, echoed across collections guides, is to pause routine reminders on disputed invoices until a human resolves them.
Should I use my accounting platform's built-in reminders instead?
Start there if your invoices already live in QuickBooks Online or Xero. Both include automatic email reminders, and Xero's run before and after the due date and weekly until payment. The limitation, noted across multiple 2026 comparisons, is that these reminders are mostly email-based and one-size-fits-all. If a client ignores email, has a dispute, or needs a real conversation, someone still has to pick up the phone. Reminder-call services and voice agents fill that gap rather than replace the ledger.
How far before an invoice due date should reminder calls start?
A common schedule, echoed by Esker's invoice payment guidance, is a friendly reminder 3 to 7 days before the due date, a notice on the due date, and follow-ups weekly past due as needed. My AI Call Center's Payment & Invoice Reminder Calls campaign places calls a few days before the due date and follows up if the payment remains unpaid, which fits that cadence. For advisory retainers, matching the call timing to your engagement agreement's payment terms keeps the reminder consistent with what the client agreed to.
