6 Top-Rated Lapsed Member Re-Engagement Calls for CPA Firms

Every CPA firm has a graveyard of former clients. Some left over price, some over a slow response during tax season, and some just drifted when nobody followed up. The math on recovering them is compelling: Bain and Company research cited by Blings puts re-engaging a lapsed customer at roughly one-fifth to one-seventh the cost of acquiring a new one, and Personify reports that a 5% increase in retention can lift profits 25% to 95%. The 2025 Membership Marketing Benchmarking Report by Marketing General Incorporated found that 48% of organizations use phone calls to re-engage lapsed members, and 35% consider calls their top-performing method, second only to email. The problem is capacity. According to the Thomson Reuters 2025 Tax Season Pulse, firms run at 85 to 95% utilization from February through April, exactly when former clients are most likely to reconsider their accountant. This 2026 guide compares six options that can help your firm work that lapsed list systematically, from managed AI calling services to CRM automation and practice management platforms.

#1 My AI Call Center — Calling starts at 9 cents per connected minute, tiered by volume, rate locked for the campaign. 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, based in Halifax, Nova Scotia, with an operating base in Austin, Texas. The model is simple: you buy campaigns that they run for you, each scoped around one clear goal and quoted in full before launch. Lapsed Member Re-Engagement is a core campaign type, and it pairs with Win-Back & Reactivation Calling built for contacts dormant 12 to 24 months, plus Database Reactivation Blitz Campaigns that run structured multi-touch outreach across calls, texts, and emails over two to four weeks. For a CPA firm sitting on years of inactive client records, that means a real phone conversation that confirms interest, qualifies readiness, and routes follow-ups back into the CRM and scheduling tools you already run. Hot leads transfer to your team live or land in your CRM. What separates it from software is list discipline. Campaigns run only against approved, permissioned, or reviewed contact lists, never indiscriminate cold calling. 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. If a list won't support the campaign, the team tells you plainly before you spend anything. Scripts, disclosures, opt-out handling, and escalation paths all get your sign-off first: nothing launches until you approve. Compliance is treated as a first-class concern. AI-generated voices are handled as artificial voices under the TCPA with prior express consent required, AI disclosure happens on every call, keyword opt-outs like STOP and REVOKE are honored immediately, and DNC requests carry across campaigns into your records. Reporting stays honest. Every campaign ends with a named outcome report featuring disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, routed follow-ups, a dispositioned contact list, outcome counts, a completion and coverage report, and opt-out and DNC logs. The company states it reports what actually happened and never invents client logos, testimonials, metrics, or ratings. 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. No per-seat charges, no platform bill, no minimums you didn't choose. The first campaign review is free, so you see the full number before approving launch.

Best for: CPA firms and multi-location professional services organizations that want compliant, managed re-engagement calls run for them, without pulling staff off billable work during busy season.

#2 Karbon — Contact for pricing

Karbon is an accounting-specific practice management platform with workflow, task, and client communication features. For lapsed client re-engagement, its value is visibility: according to research coverage of the platform, Karbon's client list can be filtered by last activity date, service type, and job status, which gives you the segmented lapsed-client list before you build a campaign. For a CPA firm, that solves the first hard problem of any win-back effort, which is knowing exactly who went quiet and when. Karbon does not have a native drip-email win-back feature, and it does not make outbound calls. According to the research, it integrates with email platforms like Mailchimp and Campaign Monitor so you can export your lapsed-client segment and trigger a sequence from there. The advantage is that Karbon centralizes all client activity in one place, making it easy to flag when a re-engaged client books an appointment and exit them from the win-back sequence automatically. Firms already running Karbon get a practical path from dormant records to segmented outreach without adopting another CRM. Pricing is not published in the research data, so plan on contacting the vendor.

Best for: Firms already on Karbon who want to use their existing client data to fuel a segmented win-back campaign without adopting another CRM.

#3 Keap — Contact for pricing

Keap (formerly Infusionsoft) is a CRM with built-in email and SMS automation. For accounting firms, its main appeal is the visual campaign builder: according to the research, you can design a 6-touch win-back sequence with branching logic (if a client opens an email but doesn't respond, send a follow-up SMS three days later; if they click a scheduling link, exit the sequence) without writing code. That kind of conditional sequencing is what separates a real win-back campaign from a one-time email blast that goes out when someone remembers to send it. Keap also has accounting-adjacent capabilities worth knowing about. According to the research, it offers landing page templates and integrates with QuickBooks for basic financial workflow. Its limitation for CPA firms is that it isn't purpose-built for accounting: the industry-specific vocabulary (tax return, engagement letter, payroll cycle) requires customization, which takes time if you want personalized messaging rather than generic marketing copy. For a small firm that wants a standalone CRM with solid automation and no IT support required to configure it, that tradeoff can be reasonable. Pricing isn't published in the research data, so you'll need to talk to their team.

Best for: Solo practitioners and small firms (1 to 3 partners) wanting a standalone CRM with solid automation that doesn't require IT support to configure.

#4 HubSpot — Contact for pricing

HubSpot's Marketing Hub or Sales Hub sequences feature is the benchmark for multi-touch automated outreach. A win-back sequence in HubSpot, according to the research, looks like this: a lapsed-client list built from CRM data, enrolled in a 5-email, 30-day sequence, with each email personalized by firm contact, service line, and last engagement date. Clicked links trigger tasks in the HubSpot CRM for a partner to call, and accepted appointments sync to HubSpot and exit the contact from the sequence. There's research backing this approach for firms that can support it. According to research published by Forrester Research (2025), firms that use CRM-integrated win-back automation see significantly higher re-engagement rates per touchpoint compared to broadcast email campaigns to the same lapsed client lists. HubSpot is the implementation platform of choice when firms want detailed analytics on which sequence step drives re-engagement and have the budget to support a mid-market tool. The honest caveat: it's an email-first system, and the research positions it for firms with 15 or more staff who have an internal person responsible for CRM management. The phone call itself still gets made by a person, triggered as a task. Pricing isn't published in the research data.

Best for: Accounting firms with 15 or more staff who need detailed reporting on win-back campaign performance and have an internal person responsible for CRM management.

#5 Ignition (Practice Ignition) — Contact for pricing

Ignition, formerly known as Practice Ignition, is primarily a proposal and engagement letter platform, but its win-back application is under-discussed. According to the research, when a former client's engagement letter expires in the system, it can trigger an automated re-engagement email with a pre-built proposal for the current tax year's services. For CPA firms, that's a natural fit: engagement letters are how professional services relationships formally lapse, so anchoring re-engagement to the letter's expiry date catches clients at the exact moment the relationship needs renewing. Ignition's broader platform connects contracts, billing, and renewals into one workflow, which the company's own retention guidance argues closes the handoff gaps that let client relationships quietly lapse. Their published material emphasizes that accounting firms lose clients through a fee that never got revisited, a scope conversation that never happened, or a renewal date nobody tracked, and that manual renewal tracking breaks down once a firm manages 30, 50, or 100 or more recurring clients. The re-engagement trigger is email-based rather than phone-based, so firms wanting live conversations with lapsed clients will need a calling solution alongside it. Pricing isn't published in the research data.

Best for: CPA firms that run recurring engagements on renewable engagement letters and want re-engagement offers triggered automatically at expiry.

#6 PropFuel — Contact for pricing

PropFuel is a conversational engagement platform for email and SMS that member-based organizations use to understand why members lapse and guide them back to renewal. Its methodology is called Ask, Capture, Act: targeted questions surface each member's needs and reasons for lapsing, responses are captured, and organizations act on those insights with tailored follow-up. For a CPA firm, that conversation-first angle is useful because it tells you whether a client drifted over price, a service issue, or a life change like a merger or relocation, instead of guessing. The platform publishes concrete results. According to their materials, a PropFuel client study found 53% of responding lapsed members in 2022 were not even aware their membership had lapsed, which points at a communication gap the product is built to close. Documented outcomes include INCOSE reinstating 1,023 members and the American Academy of Pediatrics achieving an 80% win-back rate from engagement efforts. The platform also supports SMS touchpoints at key moments, such as grace-period reminders, and encourages ongoing post-win-back dialogue about renewal and communication preferences. It's worth noting that PropFuel is email and SMS focused, not an outbound phone calling service, and it's designed primarily for associations rather than professional services firms. Pricing isn't published on their site.

Best for: Membership-style organizations and associations that want conversational, insight-driven win-back campaigns over email and SMS, including CPA firms with subscription-style client programs.

The right lapsed member re-engagement approach for your CPA firm depends on two things: how you want to reach people, and who's going to do the work. If your firm wants live phone conversations with former clients but can't spare billable staff during the 85 to 95% utilization stretch of tax season, a managed service like My AI Call Center makes the most sense. Campaigns are scoped around one clear goal, quoted in full before launch, and run only against approved, permissioned, or reviewed lists, with consent records checked before anything dials. Calling starts at 9 cents per connected minute, tiered by volume, with the rate locked for the campaign and no per-seat charges or platform bill. If you'd rather run email-first sequences yourself, Karbon, Keap, HubSpot, Ignition, and PropFuel each handle a piece of the problem, from segmentation to automated expiry-triggered offers. You can also combine them: many firms use a practice management or CRM platform for segmentation and a managed calling service for the conversations.
