Best Software for ERA Posting (2026)

Short answer

ERA posting is not one problem. It is three. Getting the 835 file from the payer is a clearinghouse function. Matching the 835 lines to open claims, handling held lines, and balancing the deposit is a posting workflow. And seeing where every client practice stands on unposted remittances at the end of the day is a management reporting problem. Most tools solve one of the three well and leave the others to spreadsheets.

Clearinghouses like Office Ally and Claim.MD do the first part: they retrieve the 835 and make it available. They do not give you a posting surface or a cross-practice reconciliation view. Practice management suites like AdvancedMD auto-post ERAs inside each provider's instance, one practice at a time. Waystar covers remittance automation at enterprise scale, with strong denial prevention on top, but the economics are designed for hospitals, not billing companies managing a book of small practices.

A billing company posting ERAs across many client practices needs the 835 matched to the claim, CARC and RARC codes translated into plain language next to the raw payer text, held lines surfaced by policy before anything is committed, PLB and recoupment segments shown as distinct entries, and a BPR check total that balances the deposit. That is the gap this list is about.

How to read this list

ERA posting tools fall into four groups, and the most common evaluation mistake is comparing across groups as if they are the same product.

• Enterprise remittance platforms (Waystar) retrieve, auto-post, and flag denial patterns at health-system scale. Strong for hospitals; the economics rarely fit a billing company's book of small practices.
• Practice-suite ERA modules (AdvancedMD) post ERAs inside the practice's own PM instance. Fine for a single provider group; a billing company gets a separate posting queue per client, not one unified surface.
• Clearinghouses (Office Ally, Claim.MD) deliver the 835 and let you download it. The posting itself happens somewhere else, usually a spreadsheet or a secondary tool.
• Billing-company posting surfaces (Medi) put every client's unposted ERA in one queue, with the codes translated, the held lines surfaced, and the deposit balanced — across the whole book.

The main options

Waystar

Waystar's remittance automation is genuinely strong at enterprise scale. Its AltitudeAI suite ingests 835 files, matches them to claims, auto-posts clean lines, and flags denial patterns before they become A/R problems. It processed more than $2.4 trillion in annual gross claims and went public on Nasdaq in June 2024 at a $3.5 billion valuation. Published pricing estimates from third-party reviewers run from roughly $200 to $800 per month on the low end for smaller groups, up to $200,000 or more annually for health systems, all custom-quoted and typically multi-year.

The honest fit question for a billing company is whether the enterprise economics make sense at the scale of a portfolio of small practices. The setup complexity, implementation timeline, and contract structure are designed for hospital procurement departments, not a billing company posting ERAs for fifteen client practices. Waystar can auto-post and predict denials better than any other option on this list at large volume. At small volume, the overhead is the problem.

AdvancedMD

AdvancedMD includes ERA posting inside its practice management suite, with auto-posting controls, exception queues, and an A/R Control Center where unresolved ERA lines surface for manual review. The posting workflow is real and functional. Per AdvancedMD's published pricing page, rates run from $429 to $1,070 per provider per month depending on the specialty tier, and volume discounts for billing companies require a custom quote from the AdvancedBiller program.

The constraint for a billing company is architectural. AdvancedMD was built as a practice platform, and its ERA workflow reflects that. Posting happens inside each practice's instance, with its own login, its own exception queue, and its own BPR reconciliation view. A billing company with twelve client practices has twelve separate ERA queues to work. Cross-practice posting volume and unposted ERA balances require manual aggregation. If a client practice added providers since your last posting session, AdvancedMD's fee went up; Medi's did not. After the Francisco Partners acquisition, some billing companies have reported new fees and slower service — confirm current terms directly.

Office Ally

Office Ally sits at the clearinghouse layer, not the posting layer, and that distinction matters when you are evaluating ERA software. Service Center retrieves 835 files from over 6,000 payers and makes them available for download. For participating payers, claim submission and ERA retrieval are included in the base plan at no per-claim cost. Non-participating payers trigger a $44.95 per month fee per unique Tax ID and Rendering NPI combination — a charge that compounds quickly as your payer mix grows.

What Office Ally does not provide: a review surface for matching ERA lines to claims, a held-line policy layer, CARC and RARC code translation, PLB segment handling, or a BPR check total that balances the deposit. The 835 arrives; the posting work happens somewhere else. Most billing companies on Office Ally do that work in a spreadsheet or a secondary PM. The Jopari acquisition in April 2026 extended Office Ally's coverage into P&C and workers' compensation claims, which is worth watching if that volume is part of your book, but it does not change the core ERA posting experience for standard health insurance billing.

Compare Medi vs Office Ally

Claim.MD

Claim.MD is a well-regarded clearinghouse for smaller billing operations. Its $120/month Unlimited plan covers unlimited claim submissions and ERA retrievals with 1,000 eligibility checks included. The 835 is available for download in standard formats including ANSI 835, spreadsheet, XML, and PDF. CARC codes appear on the transaction record alongside the remittance lines. Claim.MD holds SOC 2 Type 2, EHNAC accreditation, and CAQH CORE certification — a more complete compliance credential set than Medi's current posture.

The posting workflow, however, lives outside Claim.MD. The clearinghouse delivers the 835 and shows you the rejection reasons at the transaction level. Matching ERA lines to open claims, surfacing held lines, managing PLB recoupments, and reconciling the deposit against the BPR check total is work your team does in a separate tool. For a solo biller managing one or two practices, that might mean a PM system or a spreadsheet. For a billing company managing ten practices, the friction of stitching those pieces together per client is where Claim.MD's simplicity becomes a constraint.

Compare Medi vs Claim.MD

Medi

Medi is built for the billing company posting ERAs across a book of client practices. Every client's unposted ERA lands in one queue. The CARC and RARC codes are translated into plain language next to the raw payer text, so a poster reads "contractual obligation — the amount exceeds the fee schedule" instead of looking up CO-45. The BPR segment shows the expected check or deposit total at the top of the review screen. PLB adjustments, including recoupments from prior ERAs and interest credits, appear as their own entries rather than absorbed into the payment record.

Held lines surface before anything is committed. A poster can accept a line, reject it back to follow-up, escalate it to the denial queue, or flag it for a write-off review, all from the same screen. Denied lines cost nothing to post: ERA pricing is $0.25 for the first paid line and $0.20 for each additional paid line, with no charge for denied lines beyond the first. That pricing reflects how billing companies actually use the system — a payer that denies twelve of twenty lines on a remittance should not cost the same to process as one that pays all twenty.

Reversals route through the same posting surface. When a payer issues a reversal on a prior ERA, the held-line policy surfaces it before it hits the ledger, and the audit trail captures who posted what and under what authority. Cross-practice reconciliation is available as an aggregate view, so a billing-company owner can see total unposted ERA balance and deposit alignment across all clients without opening each practice separately.

Medi is not an enterprise denial-prediction engine. It does not predict denials before submission the way Waystar's AltitudeAI does, and it does not include an EHR, scheduling, or clinical documentation tools. It is a posting and reconciliation work surface for billing companies, priced at $20 per client practice per month with graduated volume discounts to $15 and $10 as the book grows. No per-provider fee, no contract.

See the ERA posting workflow guide for the step-by-step, and the EOB vs ERA guide if you need to explain the difference to a client practice that still receives paper EOBs.

How to choose

The questions that separate these tools for a billing company in 2026:

• Do you need 835 delivery or a posting work surface? Clearinghouses (Office Ally, Claim.MD) deliver the file. Posting the file is a separate workflow that needs a separate tool unless you are on a full PM or a billing-company posting surface.
• How many client practices are you posting for? A single practice can live inside AdvancedMD's per-instance model without much friction. At five or more practices, a cross-practice posting queue saves meaningful time per day.
• Does your pricing scale with provider count or practice count? Per-provider models (AdvancedMD at $429–$1,070/provider per its published pricing) grow every time a client hires a provider. Per-practice models (Medi at $20/practice) grow only when you add a client.
• What happens to held lines? Every ERA has lines the payer short-paid, recouped from a prior claim, or denied without a clear CARC. How the system surfaces those lines, and whether they require a manual hold or auto-post through, determines how much exception work lands on a poster each day.
• Can you balance the deposit from the posting screen? The BPR segment on every 835 tells you what the payer's check or EFT should equal. If your software does not show that number during review, your team is reconciling the deposit after the fact, in a separate step.

Where Medi fits

Medi's honest niche is the third-party billing company posting ERAs across more than a handful of client practices, where a single queue with translated codes, held-line controls, and deposit reconciliation is the difference between posting in hours and posting in days.

It is not the right tool for a solo biller managing one practice who wants the lowest possible overhead. Office Ally or Claim.MD handles that well at a lower all-in cost. It is not the right tool for a health system that wants denial prediction at scale before submission — that is Waystar's territory. And it is not a full PM or EHR; client practices need their own clinical software.

Frequently asked questions

What is the best software for ERA (835) posting in 2026?

It depends on what layer you actually need. If you need 835 delivery, Office Ally and Claim.MD are reliable clearinghouses at low cost. If you need a posting work surface that matches lines to claims, handles held lines, translates CARC and RARC codes, and balances the deposit, that is a different category. Medi is built for billing companies doing that work across multiple client practices in one queue. AdvancedMD posts ERAs per provider instance, and Waystar automates remittance at enterprise scale. The ERA posting guide covers the workflow mechanics regardless of which software you use.

What is the difference between a clearinghouse and ERA posting software?

A clearinghouse retrieves the 835 from the payer and makes it available. ERA posting software takes that 835 and gives you a work surface: matching lines to claims, surfacing held lines by policy, translating the CARC and RARC codes, handling PLB adjustments and recoupments, and confirming the BPR deposit total. Most clearinghouses stop at delivery. Office Ally and Claim.MD are examples of that layer. AdvancedMD and Medi go further — though AdvancedMD does it per practice instance and Medi does it across all client practices in one queue. The EOB vs ERA guide covers the underlying document formats.

What are CARC and RARC codes, and why does the software matter?

CARC codes (Claim Adjustment Reason Codes) explain why a payer paid less than billed. RARC codes (Remittance Advice Remark Codes) add detail — a secondary explanation or group code. Together they tell the poster whether a line was denied for a coordination of benefits issue, a contractual write-off, a missing modifier, or a patient responsibility transfer. Software that shows only the raw code forces the poster to look up the meaning in a separate reference. Software that translates the code inline — "CO-45: contractual obligation, the amount exceeds the contracted fee schedule" — saves a lookup on every line and reduces posting errors on lines the poster misread.

How does held-line policy work in ERA posting?

A held line is a remittance line that the posting software flags before committing it to the ledger. Policies vary by tool and by billing company, but common held-line triggers include: the ERA payment differs from the contracted rate by more than a configured tolerance, the line is a reversal of a prior posting, the CARC code indicates patient responsibility on an account with a zero balance, or the PLB segment contains a recoupment tied to a claim the poster has not reviewed. The practical value is catching auto-posting errors before they hit the ledger, rather than discovering a balance problem during month-end reconciliation. Medi surfaces held lines as a first-class review step; AdvancedMD has an exception queue; clearinghouses like Office Ally and Claim.MD leave that logic to whatever tool does the posting.

What does Medi charge for ERA posting, and how does that compare?

Medi charges $0.25 for the first paid ERA line and $0.20 for each additional paid line on a given 835 transaction. Denied lines after the first cost nothing. There is no separate ERA retrieval fee beyond the per-line rate. The platform fee of $20 per client practice per month covers the posting work surface, cross-practice queue, and reconciliation view. AdvancedMD bundles ERA posting into its per-provider seat ($429–$1,070/provider/month per AdvancedMD's published pricing). Office Ally includes ERA retrieval at no per-transaction cost for participating payers. Claim.MD includes ERA in its $120/month Unlimited plan. The price comparison depends on your practice count, provider count, and claim volume. The pricing calculator models the all-in number for a Medi book.

A note on the pricing figures here

The pricing shown for other vendors is gathered from their public pricing pages where they publish one, and from third-party aggregators, reseller materials, and customer reports where they do not. Many of these vendors do not publish their pricing, so these figures are approximate, may not reflect negotiated or current rates, and can change without notice. Treat them as a starting point and confirm current pricing with each vendor directly. Where a vendor does not publish its pricing, this page says so rather than presenting an estimate as fact. Medi's own pricing is published in full at /pricing.
