Lassie AI review for dental offices: what it does, what it costs, and who it fits
What Lassie automates from EFT enrollment to appeals, its reported two percent fee and $3,000 setup, practice software support, onboarding time, what users say, and the questions to ask in a demo.
By Dr. Salem Sayegh, general dentist, Glendora, California ·
The short answer: Lassie is an AI back-office service that takes a dental office’s insurance payments from EFT enrollment through posting, reconciliation, secondaries and appeals, and says it handles 98% of posting on its own. It does not publish prices; the fee has been described as two percent of what it posts plus $3,000 setup per location. It fits offices that want one vendor for the whole payment side and are already paid by EFT. Check the fee base, your practice software and the paper-check timeline before you sign.
A disclosure first: I am a general dentist in Glendora and the founder of Amalgamate Technologies, which builds Sai for Dentists, a product that overlaps with Lassie. I have kept this review to what Lassie publishes and what third parties report, marked which is which, and said where Lassie does more than we do. Everything below was checked on October 21, 2026.
What Lassie is
Lassie is made by Go Lassie, Inc., a San Francisco company. Its website describes an AI that works the insurance side of a practice: it sets up electronic payments with each payer, converts payments to EFT, posts them, matches each EFT to the insurer, patient and claim, and records the result in the practice management system. It also pulls EOBs, files secondary claims, handles appeals and follow-up, and answers questions about claims and weekly progress. Staff are asked for input only on the most complex issues.

What Lassie does well
- One vendor for the payment side. EFT enrollment, posting, reconciliation, secondaries and appeals are usually split between staff, a clearinghouse and sometimes a billing company. Lassie takes all of them.
- EFT first. Moving payers to electronic payment is what makes posting automatic. Lassie does that enrollment for you, and offices that are already on EFT start quickly.
- Reconciliation is included. Many posting tools stop at the ledger. Lassie matches each EFT to the claims it pays, the step covered in how to reconcile dental insurance deposits.
- Rolled out payer by payer. Zentist’s comparison notes that Lassie goes live one carrier at a time, so an office can check accuracy on one payer before trusting it with all of them.
What to check before you sign
- What the fee is charged on. A percentage of every claim posted grows with your collections, not with the work. See the cost table below.
- Your practice software, by name and version. Lassie’s own page names only Dentrix. Third parties add Eaglesoft and Open Dental. If you run anything else, get it confirmed in writing.
- Paper checks. Up to about eight weeks before posting is fully automatic. Offices with many paper payers should plan for that.
- How denials are worked. Lassie’s site says it handles appeals and follow-up; Zentist describes its denial management as a dashboard the office acts on. Ask to see a denial go from EOB to appeal.
- Portal-only payers. Some dental payers send no ERA and put the EOB only in their portal. Ask Lassie to show one of yours being retrieved and posted end to end.
- An existing backlog. Ask whether onboarding includes posting months of old EOBs, or starts from new payments.
What Lassie costs
Lassie quotes after a call about volume and workflow. In June 2026, its own blog described a two percent posting fee and a $3,000 setup fee per location; that post is no longer online, and Zentist’s July 2026 comparison reports the same figures. If the two percent applies to the insurance payments posted each month, it comes to roughly this.
| Insurance posted per month | Fee per month | Fee per year |
|---|---|---|
| $20,000 | $400 | $4,800 |
| $40,000 | $800 | $9,600 |
| $80,000 | $1,600 | $19,200 |
That is often less than a full-time billing coordinator, and for many offices it is a fair trade. The point is the shape: a percentage rises every time collections do. Compare it with the models inwhat outsourced dental billing costs.
What users say
Independent reviews are thin. Searching for Lassie reviews mostly turns up Lassie’s own social posts, podcast interviews with its team, and comparison pages written by competitors such as ScoutIQ and Zentist, which are useful for facts but not neutral. In a dental office group on Facebook, one commenter said a nearby office had used Lassie for about four years and was happy with it. That is a single secondhand account. The better test is to ask Lassie for two reference offices on your practice software and call them.
Who Lassie fits, and who should look elsewhere
A good fit if you:
- want one vendor for EFT enrollment, posting, reconciliation, secondaries and appeals;
- are already paid by EFT by most payers, or can wait a few weeks while the rest are moved;
- run Dentrix, Eaglesoft or Open Dental, and are comfortable with a fee tied to what is posted.
Look elsewhere if you:
- need insurance verification or claim submission from the same vendor;
- run practice software outside the three named systems;
- want a fixed price rather than a percentage, or have many payers that put EOBs only in their portals.
For those cases, Lassie alternatives for dental offices compares Lassie with Sai for Dentists side by side, and AI agents for dental offices lists the other posting vendors by practice software and pricing model.
Where Sai for Dentists differs
Since we build a product in the same space, here is how it differs, in plain terms.
- Fixed price. Sai is priced at a fixed amount, not a percentage of what is posted and not a per-claim fee, so the cost does not rise when your collections do. It is free during our startup cohort.
- Every EOB line checked against your contract. Our dental billing engine compares each allowed amount with your contracted fee schedule and checks the payer’s rules before the line is posted. An allowed amount below your contract is flagged for your team instead of being written off as a normal CO-45 adjustment. Billing specialists review anything the engine is unsure of. EOB scrubbing explains why that check matters.
- Works on screen. Sai signs in to each payer portal and posts in your practice software the way your team does, so it is not limited to payers that send ERAs or to systems with an integration.
- No vendor lock-in. Sai works inside your existing setup. Your EFT enrollments, clearinghouse, payer portals and practice software stay as they are, and claim submission, appeals and insurance verification stay with the people and tools that handle them today. Nothing has to be moved to us, so nothing has to be moved back. If you want one vendor to take over all of that instead, Lassie covers more of it.
If you are behind on posting today
Any posting tool is easiest to start when the office is current. If EOBs have already piled up, our startup cohort clears the backlog free: our team onboards your office in person, retrieves the missing EOBs, posts every payment and reconciles the deposits. Then Sai keeps you current at a fixed price, never a percentage. See thefree dental billing backlog cleanup, or theseven-step plan if you would rather do it yourself.

Common questions
What is Lassie AI?
Lassie is an AI back-office service for healthcare practices, made by Go Lassie, Inc. of San Francisco and marketed mainly to dental offices. Its website says it enrolls practices in electronic payments, retrieves EOBs, posts insurance payments to the practice management system, reconciles EFTs, files secondary claims and handles appeals and follow-up, asking staff only about the hardest cases.
How much does Lassie cost for a dental office?
Lassie does not publish prices; its website says it shares pricing after a call and gets paid when it does work for the office. In June 2026 Lassie’s own blog described a two percent posting fee and a $3,000 setup fee per location, and Zentist’s July 2026 comparison reports the same figures. Ask for a written quote that says what the two percent is charged on.
Does Lassie work with Eaglesoft and Open Dental?
Lassie’s home page names Dentrix. Third-party comparisons from ScoutIQ and Zentist list Dentrix, Eaglesoft and Open Dental, and Zentist says Denticon is not supported. Confirm your exact system and version in a demo, and ask your practice software vendor whether third-party write-back is allowed under your license.
How long does Lassie take to set up?
Lassie says offices already paid by EFT usually start in one to two weeks, and offices still receiving paper checks can take up to about eight weeks before posting is fully automatic, while payers are moved to electronic payment.
Is Lassie HIPAA compliant?
Lassie’s website says it is built for healthcare practices and signs HIPAA business associate agreements, and that security details are shared during the demo. It does not name a SOC 2 report on its home page, so ask for one, and for where payer portal logins are stored.
Are there independent reviews of Lassie?
Few. Searching for Lassie reviews mostly returns Lassie’s own social posts, podcast interviews and comparison pages written by competitors. Ask Lassie for two reference offices on your practice software, and call them.
How does Lassie compare with Sai for Dentists?
Lassie covers more of the workflow, including EFT enrollment, secondaries and appeals, and has been in the market longer. Sai for Dentists, which our company builds, differs in three ways: it is priced at a fixed amount rather than a percentage; its dental billing engine checks each EOB line against the office’s contracted fee schedule before posting, flagging underpayments; and there is no vendor lock-in, because it works inside the office’s existing setup and leaves EFT enrollment, claims and appeals where they are today. Our side-by-side comparison covers the details.
