Clauses that change with the client.

Engagement letters and agreements written once, with conditions that choose the clauses for each matter. Year-end 1099s and W-9s filled in bulk. Every version kept.

Two kinds of paperwork, one engine.

Letters that change shape with the client, and standard forms that must stay exactly as issued.

Letters and agreements

Written once in a Word-style editor, or imported from Word. Conditions choose the clauses, and loops fill fee schedules and entity lists.

  • Engagement letters
  • Client agreements and MSAs
  • Operating agreements
  • Board resolutions
  • Tax organizers
  • Filing cover letters

fillable PDFs

Government and standard forms

Upload the PDF and Mezdoc reads its form fields. SSN and EIN fields check their format, and one call fills one form.

  • 1099-NEC
  • 1099-MISC
  • W-9
  • State tax forms
  • Invoices and statements

January, in bulk.

One call per contractor fills each 1099-NEC from your payment data. Idempotency keys make a retried batch safe, and a signed webhook reports each PDF as it finishes.

Questions from firms.

Does Mezdoc file 1099s with the IRS?

No. Mezdoc fills the 1099 and W-9 PDFs from your data. Filing with the IRS and the states stays with you.

Can clients sign engagement letters on a phone?

Yes. Send a link that opens in any browser with no account. The client signs by drawing, typing or uploading a signature, and the signed PDF comes back with the signing record Mezdoc captured, including when it was signed.

What happens to letters when we change our standard terms?

Publish the new wording as a new version. Letters already sent keep rendering from the version that made them, and every earlier version stays restorable.

Bring your standard engagement letter.

Import it from Word, mark the clauses that change, and send your first client a link.
