Invoice Butler and ti3 represent two different answers to the same problem. Invoice Butler is a managed AR service: AI + human specialists handle your collections workflow end-to-end, starting around $1,000/mo for businesses doing $1M+ in revenue. ti3 is self-serve recovery software starting at $49/mo. The decision isn’t which is better; it’s whether you want to outsource AR entirely or run it yourself with software that does the heavy lifting.

Where Invoice Butler wins
-
It’s a managed service, not just software. AI + human specialists handle the full collections workflow, including disputes, supplier portal submissions, phone calls, and finding additional contacts when the primary contact stops responding. If you’d rather hand off AR entirely than run it, Invoice Butler does that.
-
AR inbox management. Invoice Butler claims to save 10-20 hours per week by managing the AR inbox, tracking promises to pay, retrying failed payments, and following up across email + phone + text. That labor-replacement value is real if you have the volume to justify the cost.
-
Phone calls handled by humans. Real human follow-up calls (not auto-call) are sometimes the right move, especially when escalating with a long-standing customer. Invoice Butler does this; ti3 does not.
-
They manage $800M+ in receivables. Genuine scale and managed-service expertise. If you’re doing $5M+ in revenue and AR is a real cost center, the math may work in their favor.
Where ti3 wins
-
Massive cost difference. $49/mo (self-serve) or $499/mo (managed) vs Invoice Butler’s $1,000/mo+ floor. If you’re an owner-operator under $1M in revenue, Invoice Butler isn’t even an option; ti3 is built for that range.
-
You stay in control. You see every email going out, you can pause or adjust the sequence per account, you keep direct relationship management. Some owners want this; some want to outsource. Match the tool to the preference.
-
Per-account analysis. Free at /analysis/. Before you spend a cent (on Invoice Butler or anything else), ti3’s analysis tells you which overdue accounts are recoverable and which to write off. Useful triage tool even if you end up using Invoice Butler for the actual work.
-
Setup in minutes, not weeks. Invoice Butler is a managed service with an onboarding period (handing over data, training their specialists on your customer relationships, etc.). ti3 you can sign up for and run an account through in 30 minutes.
-
First-party recovery, no third-party identity. Both tools communicate in your business name, but ti3’s structural promise is that no third party is involved. With a managed service, your customers may eventually realize someone else is handling the relationship.
Buyer-specific verdict
If you’re under $1M in revenue: ti3. Invoice Butler is priced for a different segment and you’d be paying for capability you can’t use.
If you’re $1M-$3M and AR takes <10 hours/week of your time: ti3. The math doesn’t work for Invoice Butler at this revenue + volume level.
If you’re $3M-$10M and AR is a real cost center (one or more people on it): Honest tie. Run the numbers. Invoice Butler at $1,000-$3,000/mo replacing a part-time AR person can pencil out. ti3 at $499/mo managed gives you the recovery sequence; you’d still own the AR ops yourself.
If you’re $10M+ with an AR team: Probably neither. Look at Upflow or Tesorio. Both ti3 and Invoice Butler are aimed below this scale.
If you’re an MSP recovering retainer non-payment: ti3. The MSP positioning (details) is specific to your problem; Invoice Butler is generic across all AR.
Frequently asked questions
Why isn’t ti3 a managed service?
We’ve found that the right answer for most SMBs under $5M is software they run themselves with strong defaults, not a full managed service. The cost difference is large and the loss of control isn’t always worth it. ti3’s $499/mo managed tier exists for businesses who want help; it’s not a full Invoice Butler equivalent (you still set policies; we run the program).
Does ti3 do disputes?
Not as a managed service. The 5-week sequence includes a built-in path for disputed invoices (pause the sequence, surface the dispute, give the customer time to respond in writing). Invoice Butler handles the entire dispute conversation for you. Different model.
Which is more cost-effective if I have 50 overdue accounts?
At 50 accounts, ti3 managed at $499/mo is roughly $10/account/mo. Invoice Butler at $1,000/mo minimum is $20/account/mo. Software wins on per-account cost; managed service wins if your time is the binding constraint.
Does ti3 do phone calls if I add them manually?
You can call any customer at any point in the sequence; ti3 doesn’t restrict that. ti3’s sequence just doesn’t automate or recommend phone calls because they tend to hurt the relationship more than they help.
