The loaded cost of an in-house biller
The salary is the visible number; the loaded cost is the real one. Add employer payroll taxes, health insurance contribution, retirement match, PTO (someone must cover the desk), practice management software seats, continuing education — and then the cost nobody budgets: turnover. Billing staff turnover runs high across the industry, and every departure means recruiting time, training time, and weeks where collections slow while the seat is empty.
For planning purposes, a sound baseline is $60,000 salary + roughly $5,000–$15,000 in burden and overhead — and that is for one biller. Practices at higher volumes often need additional seats or specialized roles (credentialing, denials, coding), each carrying the same fixed structure.
The percentage model, in actual dollars
Percentage-based billing inverts the risk. Instead of a fixed cost that exists whether or not money comes in, the fee is a share of collected cash — if nothing collects, nothing bills. Here is the arithmetic at three volumes under EntireRCM's current launch rate of 2.99% versus the in-house baseline:
| Annual Collections | In-House (Fixed) | EntireRCM @ 2.99% | Annual Difference |
|---|---|---|---|
| $500,000 | ≈ $65,000 | ≈ $14,950 | ≈ $50,050 |
| $1,000,000 | ≈ $70,000–$80,000* | ≈ $29,900 | ≈ $40,000–$50,000 |
| $2,000,000 | ≈ $130,000–$150,000** | ≈ $59,800 | ≈ $70,000–$90,000 |
*Higher volumes add burden, overtime and software seats. **Assumes a second billing FTE. In-house figures reflect salary plus loaded costs; EntireRCM figures at the promotional 2.99% rate (regular 3.32%).
Why fixed payroll is the riskier structure
A fixed billing cost is a leveraged bet on your own collections: the biller is paid in full whether the practice collects 98% of net revenue or 89%. In a down quarter — a payer slowdown, a provider on leave, a billing error discovered late — the fixed cost does not flex, and the margin absorbs all of it.
Turnover compounds that bet. When a lone biller leaves, the practice loses institutional knowledge about its own payers and templates, and the replacement spends their first months learning what the departed one knew. Industry norms mean this cycle repeats every couple of years; each transition is a collections dip that rarely shows up in any budget line.
“48% of leaders named denials and appeals their practice's largest source of revenue leakage, compared with 23% who cited front-end issues.”
Where in-house genuinely wins
Honesty matters more than salesmanship: for some practices, in-house is the right answer. Very small panels with simple payer mixes, practices whose front office doubles as billing with strong systems, and organizations with an exceptional billing manager who has already built the daily cadence may find a hybrid — in-house staff plus outsourced credentialing or denial support — beats full outsourcing.
The failure mode is not choosing in-house; it is choosing it by default and staffing it with one generalist who is expected to code, credential, appeal and report across a payer mix that would occupy a department at a hospital. That configuration produces exactly the leakage MGMA's polling describes: denials identified as the largest revenue leak while nobody owns root-cause work.
What outsourcing actually adds beyond labor
Outsourced revenue cycle is not a biller-for-hire; at competent vendors it is a full department: certified coders, a credentialing desk, a denial and appeals unit, and analytics that a single in-house hire could never cover. EntireRCM delivers that department inside your existing EHR at 2.99% of collections, with reporting the practice can audit to the claim level.
The quality gap shows up in the metrics. Better-performing practices collect 5–8% more revenue within the first 30 days and hold 4–7% less A/R in the 120+ day bucket than average practices (MGMA Better Performers data) — differences driven by daily cadence, not by heroics. A documented daily cadence is exactly what a dedicated team with specialty desks can sustain and a single overloaded generalist cannot.
The decision framework
Score your practice against these questions before deciding. If three or more point toward outsourcing, the cost math will almost certainly agree:
- Is your denial rate above 5% — or simply unknown?
- Is any single person the entire billing department (and a resignation away from a collections freeze)?
- Does your A/R aging carry more than 10–15% past 90 days?
- Do you credential new providers at least once a year?
- Does monthly reporting consist of whatever the software prints by default?
- Is your days in A/R above 40 despite stable billing effort?
- Is time-of-service collections below 30% of patient responsibility?
Running the math on your own practice
The arithmetic that matters is your own: annual collections × 2.99% versus your actual loaded payroll, software and turnover experience. EntireRCM's pricing page includes an interactive calculator that models this comparison at any collection volume, and the free audit produces the practice-specific version — including what your current denial and aging patterns say about the revenue your structure is leaving behind.
If the comparison comes out close, the deciding factor is usually risk: a variable cost that scales with collections, backed by a specialty-desk team, versus a fixed one backed by a single seat. Start with the pricing breakdown or request the free billing audit.
