Quick answer: Fax triage software is typically priced per document processed or per provider per month rather than per fax line, with implementation billed separately. The return comes from two places: labor hours reclaimed from manual document handling, and revenue protected when referrals and prior auths stop aging in a queue. For most OB-GYN practices the labor line alone clears the cost somewhere above 100 inbound documents a day, with referral conversion supplying the rest.
How vendors actually price this
Three models dominate, and knowing which one you're being quoted changes how you compare offers.
Per document processed. You pay for volume, usually with tiered rates that drop as monthly volume climbs. This is the most common model for dedicated fax triage platforms and the most honest one, because your cost tracks the work being removed. The trap is page-count multipliers — a 22-page transferred prenatal record may bill as several documents rather than one. Ask how a multi-page bundle counts.
Per provider per month. A flat rate per physician or per rendering provider. Simpler to budget and often better value for a high-volume practice with few providers, worse for a practice with many part-time providers and moderate volume. Ask whether nurse practitioners, midwives, and PAs count as providers for billing.
Platform fee plus usage. A base subscription covering the integration and a variable component tied to volume. Common when the vendor is doing significant EHR integration work, and it's often the right structure for a multi-location group.
What drives the number up or down: daily inbound volume, the number of distinct document categories you need classified, EHR integration depth, whether you need structured field write-back or document-drop is enough, and how much implementation support you want.
Implementation is usually a separate line. Ask for it as a fixed fee rather than hourly, and ask what happens if the integration runs long.
The labor math, as a formula you can run
Skip the vendor's ROI calculator and build this from your own baseline.
Annual labor cost of manual handling = documents per day × average minutes per document × (loaded hourly staff cost ÷ 60) × 250 working days.
Run it with real numbers. A practice handling 180 inbound documents a day at an average of 2.2 minutes each, with a loaded front-office cost of $28 an hour, is spending roughly $77,000 a year on document handling. That's the ceiling on what automation can save.
Then apply the straight-through rate. At 80% automation with exceptions taking 20 seconds each rather than 2.2 minutes, recovered labor lands around $59,000. That's the realistic number, not the ceiling.
Two adjustments worth making. Weight your average minutes by category — a 22-page transferred prenatal record is not a one-page lab result, and if bundles are a meaningful share of your mix, a flat average understates the baseline badly. And use loaded cost, not wage: benefits, payroll tax, and overhead typically add 25% to 35%.
If that recovered-labor number doesn't clear subscription plus amortized implementation, the case rests entirely on the second-order effects below — which are real but harder to defend to partners.
The revenue side, which is usually larger in OB-GYN
The labor line is what gets the project approved. The revenue effects are usually what make it worth doing.
Referral conversion. An OB referral worked the day it arrives converts to a scheduled appointment more reliably than one that sits three days. Patients call the next practice on the list. Measure your current time-from-receipt-to-scheduled before you start, because it's the before-number you'll need, and most practices have never measured it.
The compounding effect is specific to obstetrics: a new OB patient isn't one visit. She's a full prenatal course, a delivery, a postpartum visit, and frequently years of gynecologic care afterward. Losing one to a three-day processing delay is not a lost appointment.
Earlier prenatal entry. AJOG research on first prenatal visit scheduling found average recommended first appointments landing around 6.4 weeks of gestation, with a quarter of clinics pushing past eight weeks. Processing delay is one of the inputs to that number, and it's one of the few a practice controls directly.
Prior auth deadlines caught. Denials and peer-to-peer requests carry appeal windows. A denial discovered six days late is a denial you can't appeal, and the write-off is silent — nobody connects it back to the fax queue.
Cleaner intake data. Mis-keyed member IDs from manual entry produce denials four to six weeks later. Extraction doesn't eliminate errors, but it makes them visible at the point of capture rather than at the point of adjudication.
Hidden costs that belong in the model
Vendors rarely volunteer these. Put them in the spreadsheet before you sign.
- Integration work on your side. Even a documented API connection needs someone from your practice on calls, testing write-back, and confirming field mapping. Budget 20 to 40 internal hours for a practice administrator or whoever owns the EHR relationship.
- The ramp period. Straight-through processing doesn't start at 80%. Expect the first several weeks to run well below steady state while the system learns your document mix and your senders' formats. During shadow mode you're carrying both the software cost and the full manual process.
- Exception handling, permanently. A share of your volume will never automate — handwriting, multi-patient batch faxes, poor scans. That's ongoing staff time, not a temporary condition, and it should be in the model as a recurring cost rather than netted out.
- Interface engine licensing. If you're on an on-prem EHR that needs Mirth or Rhapsody to bridge, that may be a cost you don't currently carry.
- The second system problem. If the vendor's output lands in their dashboard rather than your EHR, your staff are now checking two places. This is a real cost even though it never appears as a line item, and it's the reason to insist on structured write-back into the chart.
Honey Health is one of the vendors in this category; its fax triage agent writes into the existing EHR rather than holding results in a separate interface, which is worth confirming with any vendor you evaluate because it determines whether the exception queue adds a workflow or replaces one.
What a realistic payback window looks like
For a practice above roughly 100 inbound documents a day with a packet-heavy mix, payback on labor alone typically lands somewhere in the first year — often sooner once referral conversion is counted, though conversion improvements take a quarter or two to show up in the numbers.
The sequence in practice: months one and two are cost with no return, because shadow mode runs in parallel with the manual process. Month three is partial, as categories cut over one at a time. Steady state arrives somewhere in month four or five, and that's the first month your recovered-labor number is real.
Don't promise partners a payback date inside the first quarter. The implementations that damage credibility are the ones where someone committed to a number before the ramp curve was understood.
Ask every vendor for their median and 90th-percentile implementation time on your specific EHR. The median tells you what's typical. The 90th percentile tells you what your model needs to survive.
Which practices don't clear the bar
Being honest about this is more useful than a universal yes.
Under 50 inbound documents a day. Total handling time is small enough that a disciplined manual process inside an organized EHR fax module is adequate. The savings won't clear a subscription, and you'd be adding an integration project to solve a problem that isn't costing much.
A correspondence-heavy mix. If most of your inbound volume is single-page letters and routine results rather than multi-page transferred records and pathology, the capability you'd be paying for — splitting and structured extraction — isn't the capability you need.
Mid-EHR-migration. Adding a second system during or right after an EHR change is how implementations fail, and any problem becomes impossible to attribute. Wait a quarter.
No internal owner. A half-finished rollout costs more than no rollout. If nobody can own eight weeks of implementation this quarter, the honest answer is to wait for a quarter when someone can.
Frequently Asked Questions
How much does fax triage software cost per month?
It depends on pricing model and volume, so ask for a quote against your actual document count rather than a list price. Per-document pricing is the most common structure for dedicated triage platforms, with tiered rates that fall as volume rises. Get the multi-page bundle counting rule in writing, since transferred prenatal records can bill as several documents.
Does fax triage software let us reduce front-office headcount?
Most practices adopting it are trying to stop needing a hire they can't make rather than cutting existing staff. Front-desk and medical assistant roles are among the hardest to fill, and the practical outcome is usually redeploying recovered hours into referral conversion, prior auth follow-up, and patient calls rather than reducing the team.
How do we build a business case our partners will accept?
Start with two weeks of measured baseline — documents per day by category and timed handling per category. Convert to annual labor cost using loaded staff cost, apply a conservative 75% straight-through rate, and compare against subscription plus amortized implementation. Present referral conversion as upside rather than as the core case, since it's harder to prove in advance.
Is implementation cost negotiable?
Often, particularly if you're the first customer on your specific EHR or if you commit to a longer term. Ask for implementation as a fixed fee rather than hourly, and ask what happens to the fee if the integration runs past the quoted timeline. A vendor unwilling to cap it is telling you something about their confidence in the estimate.
What should we measure after go-live to prove it worked?
Four things: straight-through processing rate by document category, exception queue time per day, time from fax receipt to chart filing, and time from OB referral receipt to scheduled appointment. The first two prove the software works. The last two prove it changed the operation, which is the part your partners actually care about.
