Mezdoc vs Anvil.
Both fill PDFs over an API well. The differences show up in what you pay per signed packet, where conditional logic lives, and what it costs to put a white-labeled form in front of an insured.
Pick Mezdoc if you assemble conditional, multi-document packets and want eSignature without a per-signature meter, at a price a small MGA can budget. Pick Anvil if you need Document AI today, or an established enterprise vendor with years of named-customer history. Below is the math, verified against Anvil's public pricing page on June 12, 2026.
Three differences you will feel.
The $425 wall
Embedded, white-labeled signing is table stakes for an MGA putting forms in front of agents and insureds. On Anvil that requires Product Pack: $425 a month, $5,100 a year ($4,080 billed annually), before any usage. On Mezdoc, embedding and eSignature are included from the first paid plan at $49 a month.
The double-billed packet
On Anvil, a workflow that ends in a signature bills both meters: $1.00 for the workflow submission plus $1.50 for the e-sign packet. Every completed signed packet costs $2.50 before the platform fee. On Mezdoc, signing itself is never metered: no per-signature or per-envelope fee on any plan. Plans include PDF and workflow quotas, with flat published overage beyond them.
Conditional logic, held hostage
Anvil's lower tiers get basic conditional logic. Advanced logic and dynamic workflows sit in the Enterprise tier, at custom pricing. Conditional, rules-based packet assembly is Mezdoc's core feature on every plan, including Free: pages, documents, and endorsements enter or leave the packet based on the data.

What you get, and where.
| Capability | Mezdoc | Anvil |
|---|---|---|
| Conditional packet logic | IF rules on pages, documents, and whole packets. Every plan, including Free. | Basic conditional logic on lower tiers. Advanced logic and dynamic workflows are Enterprise-only. |
| eSignature | Included on every plan, watermarked on Free, unwatermarked from $49/mo. No per-signature or per-envelope fee. | Separate metered product (Etch): $1.50 per e-sign packet on top of plan fees. |
| A signed, multi-document packet | One workflow run against your plan quota; beyond quota, flat published overage per run. | $2.50 per completed packet: $1.00 workflow submission + $1.50 e-sign packet. |
| Embedded forms and white-labeling | Embedding on every plan. Watermark removed from $49/mo. | White-labeling, interactive and embedded signing start at Product Pack, $425/mo. |
| Staging and production environments | Versioned templates on all plans; a separate staging environment on Scale. | No staging and production split in the public documentation. |
| Document AI (auto field detection) | Not yet. Anvil is genuinely ahead here. | Real and good: box finding, field labeling, schema mapping. $99/mo AI Pack. |
| API | REST with idempotency keys and HMAC-signed webhooks. | GraphQL, mature, 40 req/s on Product Pack. |
| Billing model | Flat plans with published overage. Alerts at 80% and 100% of quota. | Metered, billed on completed packets only (genuinely fair). Prepaid bulk credits expire after one year. |
Based on both products' public documentation and pricing as of June 12, 2026. Mezdoc does not claim a feature it does not have, in either column.
Where Anvil is genuinely better.
A comparison page that finds zero strengths in the competitor is an ad. These are real, and if they matter more to you than the pricing math above, buy Anvil.
Document AI is real
Anvil's automatic box finding and field labeling works, and Mezdoc has no equivalent yet. If your team uploads hundreds of unfamiliar PDFs a month, that feature earns its $99.
Completed-only billing is fair
Anvil bills workflow submissions and e-sign packets only when they complete. Abandoned packets cost nothing. That is customer-friendly and we will not pretend otherwise.
An established brand with named customers
Carta, Vouch, Pathpoint, Ascend. Anvil has years of production history, SOC 2 Type II, and a mature GraphQL API. Mezdoc is the newer product; our compliance posture is documented on the security page.
Enterprise compliance path
If you need HIPAA with an established vendor today, Anvil Enterprise has the longer track record. Mezdoc offers a HIPAA BAA on Enterprise as well; ask us where we are before you assume parity.
