Smith.ai vs Ironclad

Smith.ai is a reception layer: a hybrid of AI and hundreds of North-America-based live agents that answer your phones 24/7, qualify callers, book appointments, and run payment-collection conversations. It’s a mature, proven service. But it’s built to be general-purpose, and per its own materials the bulk of its reviews come from legal practices, not contractors.

Ironclad is a back office. It does what a receptionist does, answering every call 24/7, disclosing it’s AI, and booking the job, and then it keeps working after the call ends. It follows up on every estimate until it gets an answer, chases overdue invoices, and re-engages customers who’ve gone quiet. Every action it takes carries a deterministic receipt you can audit.

The simplest way to say it: Smith.ai is staff for your phone line. Ironclad is staff for your whole revenue cycle, billed on what it brings back.

Yes. Smith.ai offers a payment-collection service that combines AI and human agents, handles everything from consultation deposits to past-due balances, and integrates with payment processors like Square and PayPal, without the 30 to 50 percent cut traditional collection agencies charge.

The difference is the billing model. Smith.ai’s collection work rides on top of your flat monthly plan and per-call fees, so you pay for the capacity whether or not a dollar comes back. Ironclad’s collections ride the same aligned model as everything else: the 15% share applies only to receivables that actually cleared, proven by the receipt chain, on top of a flat monthly for the office. Every dollar of the share traces to the invoice and message that earned it.

Partially. Per Smith.ai’s documentation, it has a native integration with Housecall Pro that maps callers to client records and books appointments directly into the account, plus a direct connection to ServiceTitan where call details flow in automatically and create work orders. That covers those two platforms.

Outside those two it thins out. Per third-party comparison sources, Jobber requires Zapier as a middleman (an extra subscription, not a native write), and FieldEdge and other platforms aren’t clearly documented as native. Those Jobber and FieldEdge specifics come from third-party articles, not Smith.ai’s own docs.

Ironclad reads across the full set: Housecall Pro, Jobber, ServiceTitan, FieldEdge, Service Fusion, Workiz, Kickserv, Google Calendar, and spreadsheets. It books jobs natively into Jobber today, with the rest of the set on the integration roadmap, so it works on top of what you run instead of forwarding you a lead to re-key.

Smith.ai is a flat monthly subscription plus per-call add-ons, month-to-month with no long-term contract and a 30-day money-back guarantee, all real strengths. Per its pricing page, the managed 24/7 AI Receptionist plan is $500/month, and live-agent plans run $675/month for 90 calls and $1,350/month for 200 calls. On top of the base, several functions are metered, including live-agent handoff at $3/call and custom AI training at $2,000 one-time (included on managed plans). The structure to understand: you pay the monthly fee, plus per-call fees for the things that actually move money, regardless of outcome.

Ironclad is built around aligned incentives. Going live is a flat monthly for the office plus 15% of the receivables it provably recovers, each dollar on a receipt you can audit. Smith.ai’s bill scales with call volume whether or not a dollar comes back; Ironclad’s upside is the 15% recovery share, so it scales with receivables it proves it brought back.
