Honest Taskers, Access Healthcare, and Sunknowledge Services lead this year's shortlist of outsourcing partners for medical billing companies, seven firms ranked on how they absorb a billing company's overflow work, from claims submission and payment posting to accounts receivable follow-up, denial rework, and charge entry for the practices you bill for. Every firm here is bought by a billing company rather than by a practice, so the comparison is about capacity, security posture, and how you pay for the work.
Disclosure: Honest Taskers publishes this list and appears at position 1. We're judged on the same five published criteria as every other company here.

How we chose the best outsourcing partners for medical billing companies
We ranked these firms on five facts, each read at the provider's own website on August 21, 2026. Those facts are whether the firm states it works for billing companies and revenue cycle firms rather than only for practices, where the work is delivered, published pricing, the engagement model you buy under, and the security and coding credentials the firm names. A billing company is not the same buyer as a clinic. You already own the payer relationships and the client contracts, so what you're purchasing is trained capacity that plugs into your existing workflow, plus a security story you can repeat to your own clients. Blank facts read "not publicly listed" instead of a guess, and we flag any firm whose only named compliance is HIPAA, since your clients will ask for more than that.
Best outsourcing partners for medical billing companies compared
The table ranks all 7 on the same columns, Honest Taskers first because we publish the list. Facts were read August 21, 2026 and change often, so treat them as a starting point, not a quote.
| Company | What it takes on for a billing company | Delivery locations | Published pricing | Engagement model | Compliance named |
|---|---|---|---|---|---|
| Honest Taskers | Placed staff for claims submission, payment posting, AR follow-up, denial rework, charge entry | US clients; recruiting in the Philippines, Latin America, India and Pakistan | $10.00–$12.65/hr | Staffing by the hour, your workflow | Compliance officer; HIPAA compliance verified by Accountable; BAA when PHI is accessed |
| Access Healthcare | Front, mid, and back-end revenue cycle work; names medical billing companies and revenue cycle partners as client types | Dallas, Texas; Chennai, India; Manila, Philippines | Not publicly listed | Outsourced service plus its Echo automation platform | Not publicly listed |
| Sunknowledge Services | Pre-billing, mid-billing, and post-billing support, prior authorization, AR and denial management | New York headquarters; states US delivery across all US time zones | Not publicly listed | Outsourced service, per-process | HIPAA; ISO 27001:2022 |
| Plutus Health | Billing, coding, denial management, AR, patient registration, eligibility, prior authorization | Dallas, Texas; states coverage in 40+ US states | Not publicly listed | Outsourced service with robotic process automation | HIPAA; SOC 2 Type II; AAPC-certified coding audits |
| Outsource Strategies International | Medical and dental billing and coding, eligibility, prior authorization, denial and AR management | Tulsa, Oklahoma; states service in all 50 states | Not publicly listed | Outsourced service, custom packages | Says it works to HIPAA and SOC 2 Type II standards; AHIMA and AAPC certified coders |
| Practolytics | Billing, coding, eligibility, pre-authorization, credentialing, plus healthcare staffing | Columbia, South Carolina and Duluth, Georgia | Not publicly listed | Outsourced service, plus staffing | HIPAA; AAPC and AHIMA certified coders |
| 24/7 Medical Billing Services | Billing, coding, credentialing, eligibility, denial management, AR follow-up, specialty billing | Marietta, Georgia and Austin, Texas; also names Mexico and South America | Not publicly listed | Outsourced service, per-specialty | HIPAA only |
Two things stand out. Only one firm on this list publishes a rate, which means budgeting a partner takes a quote in six cases out of seven. And the engagement model splits the list cleanly: you either buy hours and keep the work inside your own process, or you hand a process out and buy the result. That choice matters more than any feature comparison, because it decides who owns the payer follow-up strategy your clients are paying you for.
1. Honest Taskers
Best for: billing companies that want extra billers working inside their own system and process, billed by the hour, without handing a client account to another billing firm.
Pricing: $10.00–$12.65/hrLocation: US clients; PH, LatAm, India and Pakistan recruitingModel: Staffing by the hourFirst hire: Two-week working trial
Honest Taskers is a healthcare staffing company, not a billing company, which is the reason it sits first for this buyer. You add people rather than outsource a process, so your payer rules, your escalation paths, and your client relationships stay where they are. Placed staff handle claims submission, payment posting, accounts receivable follow-up, denial rework, and charge entry inside your billing and practice management systems, from AdvancedMD and Tebra to athenahealth and eClinicalWorks. Candidates are trained on HIPAA and data privacy under a dedicated compliance officer, work in your time zone, and a Business Associate Agreement is signed before anyone touches protected health information, with HIPAA compliance verified by Accountable. Rates begin around $10 an hour and reach about $12.65 depending on role, background, schedule, and location. Every client gets a Customer Success Advocate and a two-week working trial with their first hire, and Honest Taskers reports 99.6% average monthly retention, so the biller who learns your top payers stays on them. See the full virtual medical billing service for role details.
Limitation: this is staffing, so your team still owns claim accuracy, payer strategy, and the outcome you promised your clients, and there is no percentage-of-collections option if you would rather buy a result.
2. Access Healthcare
Best for: billing companies large enough to hand off a whole process, and the only firm here that names billing companies as a client type on its own site.
Pricing: Not publicly listedLocation: Dallas, Chennai, ManilaModel: Outsourced service plus automationTrial: Not publicly listed
Access Healthcare organizes its work the way a billing company already thinks, splitting front-end, mid-cycle, and back-end revenue cycle into separate services you can buy one at a time. Front-end covers scheduling, eligibility verification, prior authorization, and registration. Mid-cycle covers charge entry and audit, medical coding, clinical documentation improvement, and revenue integrity. Back-end covers remittance processing, accounts receivable, denial management, credit balance, and provider enrollment. Its client list explicitly includes medical billing companies and what it calls revenue cycle partners alongside hospitals, dental practices, and payers, which is rare on a site of this kind. The firm also sells an automation layer it calls Echo, including autonomous coding and payment tools, and reports a 60% reduction in cost to collect from day one, a company-reported figure. Delivery runs from Dallas, Chennai, and Manila.
Limitation: its site names no security certification at all, which is awkward when your own clients ask what standard their data is held to.
3. Sunknowledge Services
Best for: billing companies that need a partner with a named information security certification and a long operating history.
Pricing: Not publicly listedLocation: New York; states US-wide deliveryModel: Outsourced service, per-processTrial: Not publicly listed
Sunknowledge Services sells revenue cycle work in three blocks, pre-billing, mid-billing, and post-billing, so a billing company can outsource only the part it is short on. Prior authorization is its most visible line, alongside billing and coding, accounts receivable and denial management, eligibility verification, charge entry, credentialing, and medical data entry. It names HIPAA and ISO 27001:2022, and the ISO certification is the thing that separates it from most firms at this size. Company-reported numbers include 19 or more years in business, more than $43 billion collected to date, coverage of 38 or more specialties, and a 97% prior authorization approval rate. The site describes delivery from a New York headquarters across all 50 states and all US time zones.
Limitation: no rates are published and the site does not say where its production teams sit, so ask before you make promises to a client about data location.
4. Plutus Health
Best for: billing companies serving behavioral health, surgery centers, or private-equity-backed groups, where audited security is part of every deal.
Pricing: Not publicly listedLocation: Dallas, TexasModel: Outsourced service with automationTrial: Not publicly listed
Plutus Health is the strongest security story on this list for a billing company that has to answer a client questionnaire, because it names SOC 2 Type II alongside HIPAA and AAPC-certified coding audits. Services run from patient registration, eligibility verification, and prior authorization through charge entry, claim submission and scrubbing, denial management, and accounts receivable, with inpatient coding, HCC coding, and risk adjustment validation on the coding side. Its stated client types are useful for a billing company deciding whether the fit is real: behavioral health including applied behavior analysis and substance use disorder, ambulatory surgery centers, free-standing emergency rooms, multi-physician enterprise practices, private-equity-backed platforms, and independent specialty groups. Company-reported figures include 1,600 agents, 25 automation agents, $1.7 billion in annual claims, more than 9,000 providers, and 15 or more years of operation.
Limitation: pricing is quote-only, and the specialty concentration means a general primary care book may not be its sweet spot.
5. Outsource Strategies International
Best for: billing companies with a dental book alongside the medical one, since few partners cover both properly.
Pricing: Not publicly listedLocation: Tulsa, OklahomaModel: Outsourced service, custom packagesTrial: Not publicly listed
Outsource Strategies International runs medical and dental revenue cycle side by side, which matters if part of your client base is dental practices and you don't want a second vendor for insurance verification and dental claims. The service list covers medical billing and coding, dental billing and insurance verification, eligibility verification, prior authorization, patient appointment scheduling, denial management, and accounts receivable, plus an artificial-intelligence coding platform it calls MedGenX. The firm says it works to HIPAA and SOC 2 Type II standards and that its coders hold AHIMA or AAPC certification, and it reports more than 21 years of operation from Tulsa, Oklahoma, serving all 50 states. Cost claims on the site are framed as savings of up to 40%, a company-reported figure with no rate behind it.
Limitation: the site says it works to SOC 2 Type II standards rather than saying it holds the report, and those are different claims, so ask which one applies.
6. Practolytics
Best for: billing companies that want both outsourced processes and placed staff from the same partner, on US soil.
Pricing: Not publicly listedLocation: Columbia, SC and Duluth, GAModel: Outsourced service plus staffingTrial: Not publicly listed
Practolytics is the one firm here that sells both models openly, listing healthcare staffing and virtual medical assistant services next to its outsourced revenue cycle work. For a billing company that means you can hand off credentialing or coding as a process while adding hourly people to your own accounts receivable bench, under one contract. The service list runs from eligibility and benefits verification, pre-authorizations, and medical coding through compliance audits, practice consulting, insurance contract negotiation, and medical transcription. It names HIPAA and says its coders hold AAPC and AHIMA certification, and reports 28 or more specialties, a 98% claims approval rate, and a 48-hour claim turnaround, all company-reported. Delivery is from Columbia, South Carolina and Duluth, Georgia.
Limitation: the site pairs "trusted since 2014" with "20+ years experience", so ask which figure describes the company and which describes its leadership.
7. 24/7 Medical Billing Services
Best for: billing companies that need a specialty book covered fast, such as durable medical equipment, pharmacy, or emergency room billing.
Pricing: Not publicly listedLocation: Marietta, GA and Austin, TX; also Mexico and South AmericaModel: Outsourced service, per-specialtyTrial: Not publicly listed
24/7 Medical Billing Services organizes itself by specialty rather than by process, publishing separate lines for durable medical equipment, pharmacy, mental health, emergency room, ambulatory surgery center, and radiology billing on top of general billing, coding, credentialing, denial management, eligibility verification, and accounts receivable follow-up. That structure suits a billing company that has just won a client in a specialty it has never touched and needs someone who already knows the payer rules. The firm reports more than 20 years of experience, a 98% clean claim rate on first submission, and cost reductions of up to 50%, all company-reported. Offices are in Marietta, Georgia and Austin, Texas, and the site also names Mexico and South America among its locations.
Limitation: HIPAA is the only compliance it names, with no information security certification behind it, which is the weakest security position on this list.
Should a medical billing company add staff, outsource the work, or buy automation?
Add staff when the work is yours to keep. If your clients are paying for your payer knowledge and your escalation habits, hourly people working inside your own system preserve that, and an in-house medical records and billing specialist earned about $51,140 a year, roughly $24.59 an hour before benefits, according to the U.S. Bureau of Labor Statistics May 2025 wage data for medical records specialists, against roughly $10 to $13 an hour for placed remote staff. Outsource a process when you want to stop managing it, which is the right call for prior authorization queues, credentialing, or a specialty you don't want to learn, and it is what most firms on this list sell. Buy automation for volume that is genuinely repetitive, since claim scrubbing and remittance posting are pattern work, but automation will not call a payer about a stalled claim or explain a denial trend to your client. Don't outsource an entire client account to another billing firm unless you're comfortable that the firm now knows your client, your rates, and your weak spots. For a fuller picture of the day-to-day work you would be handing over, see the medical billing duties breakdown.
What are the risks when a medical billing company outsources part of its own work?
The risks are different from a practice's risks, because you are the covered entity's business associate and you are now adding a subcontractor underneath yourself. Four questions surface most of it.
- The subcontractor chain. Ask for the subcontractor Business Associate Agreement in writing, since your client's agreement with you in all likelihood restricts who else can touch the data and where.
- Client visibility. Ask whether the partner will ever contact your clients directly, and whether its staff appear under your brand or its own, because a partner that also sells handing over billing puts a competitor sitting inside your accounts.
- Claim accuracy and rework. Ask how charge entry and coding accuracy are checked and who pays for rework, since a denial created by a partner still lands on your client's aging report.
- Security evidence, not security language. Ask for the actual report or certificate. Three firms here name only HIPAA, and "works to SOC 2 standards" is not the same sentence as "holds a SOC 2 Type II report".
- Time-zone and payer hours. Ask what fraction of the team overlaps US business hours, because payer calls and client conversations happen during the day.
How do these firms price work sold to a medical billing company?
Pricing here splits into three shapes, and only one of them is published. Hourly staffing is the transparent option: Honest Taskers begins around $10 an hour and reaches about $12.65 depending on role, background, schedule, and location, which you can budget against a client contract directly. Per-process outsourcing is the most common shape on this list, quoted per transaction, per chart, or per full-time equivalent, and every one of Access Healthcare, Sunknowledge, Plutus Health, Outsource Strategies International, Practolytics, and 24/7 Medical Billing Services keeps that number behind a sales conversation. Percentage-of-collections pricing exists in the wider market and suits a firm that wants the partner to carry outcome risk, but none of the six here publishes a percentage either. What that means practically is that you cannot compare this list on cost from public information, so ask every firm for the same unit, usually cost per claim or cost per full-time equivalent per month, and hold them to it. Rates and quotes were checked August 2026. For the systems your team and any partner will both live in, see the medical billing tools and software guide.
What should a medical billing company look for in an outsourcing partner?
The things that matter most are whether the firm sells to billing companies on purpose, what security evidence it can produce, whether it works in your systems, and whether it competes with you.
- Stated fit with your buyer type. A firm that names billing companies or revenue cycle partners as clients has already built for white-label work. Access Healthcare is the only one here that says so in writing.
- Security evidence you can forward. ISO 27001 or a SOC 2 Type II report gives you something to send your client. HIPAA language alone does not.
- Coding credentials on the record. AAPC or AHIMA certification named on the site is worth more than a claimed accuracy rate with no audit behind it.
- Your stack and clearinghouse. Confirm hands-on experience with your billing and practice management systems and your clearinghouse, such as Availity or Waystar, before the first invoice.
- A clean competitive line. Ask directly whether the firm sells whole-service billing to practices in your market, and get non-solicitation terms if it does.
How does a medical billing company start with an outsourcing partner?
To start, decide first whether you are buying hours or buying a process, because that single decision removes most of this list either way.
- Pick the work to move first, usually the queue that is hurting, such as aged accounts receivable, prior authorization, or charge entry backlog.
- Decide the model. Hours keep the process yours; per-process outsourcing hands it over along with the management of it.
- Shortlist two or three firms, then ask all of them to quote the same unit so the numbers are comparable.
- Get the subcontractor Business Associate Agreement and the security evidence in hand before any data moves.
- Run a bounded pilot on one client or one payer, measure clean claim rate and days in accounts receivable against your own baseline, then expand.

Methodology and sources
We read each company's own website on August 21, 2026, recording whether it states it serves billing companies or revenue cycle firms, delivery locations, published pricing, engagement model, and named compliance and coding credentials. Wage context is from the U.S. Bureau of Labor Statistics May 2025 Occupational Employment and Wage Statistics for medical records specialists. Where a company didn't publish a fact, we marked it "not publicly listed"; self-stated figures such as collection totals, accuracy rates, and cost savings are labeled company-reported and were not independently audited. Rates are volatile and were captured as dated points, not permanent quotes.
