Switching billing vendors is one of the highest-risk events your practice will go through. AR gets dropped in the handoff. Old denials sit unworked. The new vendor starts “fresh” — which is great for them and terrible for your aging buckets. Ninety days later, you’re looking at a cash flow gap that nobody warned you about.
Most practices figure this out the hard way. The vendor sales call was smooth. The transition was “simple.” Then collections slow down, and nobody can quite explain why.
Here are the seven questions to ask — of any vendor you’re evaluating, and of yourself — before you sign anything. They’re not the questions vendors want you to ask. They’re the questions that actually protect your cash flow.
1. What happens to my open AR on day one?
This is the question vendors are most prepared to deflect. They’ll tell you they “handle the transition.” They’ll show you a slide with a smooth ramp-up curve. None of that answers the question.
What you actually want to know: who works your aging AR — the claims that were already in flight when the contract starts? Some vendors quietly leave it for you. Some commit to working it but never get around to it because their team is busy onboarding your new claims. Some charge extra for it as a separate “clean-up project.”
Get the answer in writing. Specifically: “For claims with dates of service before [start date], what’s your responsibility, what’s mine, and what’s the deadline for working them?” If the answer is vague, the answer is “nothing.”
2. Who works my account, and how do I reach them?
Most billing companies are built around shared work pools. Your claims go into a queue. Whichever AR caller is free works the next one. That’s efficient for the vendor. It also means nobody knows your payer mix, your specialty quirks, or which claim adjuster at Aetna actually picks up the phone.
Ask whether you get a named team. Ask who the single point of contact is. Ask whether that person responds to email within four hours or four days. Ask what happens when the team lead goes on vacation.
If the answer involves a ticketing system, you’re a ticket. That’s fine for some practices. It’s not fine for any practice trying to fix a problem.
3. What does “denial management” actually mean to you?
Every vendor says they do denial management. Almost none of them root-cause denials. The default workflow is: claim denies, AR caller resubmits with whatever information seems missing, claim denies again, AR caller appeals, claim eventually pays at a lower rate or writes off.
That’s not denial management. That’s denial cleanup.
Real denial management means tracking why denials happen by code, by payer, by provider. It means feeding that information back upstream — to your front desk, your coding team, your providers — so the same denial stops happening. CO-4 keeps appearing? Someone needs to fix the modifier issue at the source. CO-16 climbing? There’s a documentation gap nobody’s talking to your providers about.
Ask the vendor: “Can you show me a denial trend report from one of your existing clients — with names redacted? I want to see how you categorize and report on denial patterns over time.” If they can’t, they don’t do this.
4. How do you handle underpayments?
This one separates serious vendors from the rest. Most billing companies post payments and move on. They don’t reconcile against your fee schedule, so when a payer reimburses below contracted rate, nobody catches it. The money quietly disappears.
On a small practice, underpayments add up to thousands of dollars a month. On a multi-provider group, it’s six figures a year.
Ask: “Do you reconcile every payment against the contracted fee schedule? How do you flag and pursue underpayments?” If they pause before answering, they don’t do it.
5. What’s your reporting cadence — and what’s actually in the report?
“Monthly reporting” usually means a dashboard with last month’s numbers. Days in AR. Collections. Maybe denial rate. No commentary. No insight. No “here’s what changed and why.”
That’s a spreadsheet, not a report.
Ask whether you get weekly updates on what’s actually happening — AR movement, claims at risk of timely filing, denial patterns that emerged this week. Ask whether someone explains the numbers, or whether you’re left to interpret them yourself.
A monthly PDF with no narrative is a vendor checking a box. A weekly note that says “Here’s what we noticed, here’s what we did about it, here’s what needs your attention” is a partner.
6. What’s the offboarding plan if this doesn’t work?
Most contracts bury this in the fine print. Read it. Specifically: who owns your data, how is it handed back to you, and what’s the timeline? If you decide to switch back in-house or to another vendor in 18 months, can you actually take your AR notes, denial history, and payer correspondence with you?
Some vendors make exit so painful that practices stay even when they’re unhappy. Don’t sign without understanding what leaving looks like.
7. Am I switching for the right reason?
This one’s for you, not the vendor.
Sometimes practices switch because their current vendor is genuinely bad. Slow, sloppy, unaccountable. That’s a valid reason.
Sometimes practices switch because they think a new vendor will fix problems that aren’t actually billing problems — staffing turnover at the front desk, providers under-documenting, a payer mix that’s getting worse, a fee schedule that hasn’t been negotiated in three years. A new billing vendor won’t fix any of that.
Before you switch, get an honest read on whether your billing vendor is the actual problem. A 60-day audit from someone with no skin in your decision — not the new vendor pitching you, not the old vendor defending themselves — will tell you whether switching solves your problem or just gives you a new logo on the same problem.
If you’re going to switch, do it with eyes open
Switching billing vendors is one of the most disruptive things you can do to your revenue cycle. It can absolutely be the right call. But it’s only the right call if you ask the questions above and get answers you can actually verify — not promises in a pitch deck.
If you’re working through this decision and want a second pair of eyes — someone who’s managed transitions from both sides of the table — that’s exactly the kind of conversation we have. No sales pitch. No deck. Just a real read on your situation.
