How to Fax Business Contracts — Documented Delivery for Binding Agreements
A business contract is only as good as the record of who signed it and when each side received it. Manufacturers, retailers, and construction firms still fax executed agreements to suppliers, customers, and subcontractors who keep paper-format originals in their vendor files, or whose internal intake process expects a hard copy. Fax also bridges the gap when two parties run incompatible e-signature platforms but both need a timestamped delivery record. Send FAX Mail handles the transmission and emails back a confirmation you can drop straight into the contract file.
How to Fax a Business Contracts
- 1Ensure the contract has been reviewed, negotiated, and finalized — do not fax a draft marked for discussion as a final executed document
- 2Include all exhibits, schedules, and attachments referenced in the contract body — incomplete contracts create disputes about which terms were agreed to
- 3Obtain all required signatures from authorized signatories; verify that the signing party has authority to bind the entity (officers, members, or agents with documented authority)
- 4Include the contract reference number, effective date, and parties' full legal entity names on the first page
- 5Log in to Send FAX Mail, upload the executed contract package, and fax to the counterparty's authorized contact fax number (confirm from the contract signature block or prior correspondence)
- 6Save the delivery confirmation and attach it to your contract file — the timestamp documents when the counterparty received the executed agreement
Document Format
Signature blocks must identify the signing party's full legal name, title, and the entity they are signing on behalf of. Initials on every page of a multi-page contract confirm page integrity — include this if your contract requires it. Number all pages and include the contract reference number as a footer. If the contract contains pricing tables, payment schedules, or specification sheets, ensure these scan clearly at standard fax resolution and that dollar amounts are unambiguous.
Legal Considerations
Faxed signatures are legally binding under the Electronic Signatures in Global and National Commerce Act (ESIGN) and the Uniform Electronic Transactions Act (UETA), adopted in 49 states. A faxed signature is treated as a valid original for most commercial contract purposes. Retain the executed contract and fax delivery confirmation as part of your contract management records — these documents are essential if a dispute arises about whether a contract was executed, when it was received, or what terms applied. Some contracts (real estate conveyances, wills, certain securities agreements) require original wet signatures or have specific execution formalities that fax alone may not satisfy.

Federal agencies still write fax into new rules and notices
The Federal Register — the daily journal of U.S. federal rulemaking — regularly publishes rules and notices that reference fax as an accepted or required submission channel for filings with agencies like the IRS, SSA, and CMS. That is why fax remains a live requirement for many official forms even as electronic portals expand.

Faxing a Business Contracts — FAQ
For the large majority of commercial contracts, yes. ESIGN and UETA treat a faxed signature as valid, and courts have repeatedly upheld them as evidence of intent to be bound. The exception is any contract that specifically calls for an original wet signature, so read your contract terms if you have doubts about a particular deal.
The confirmation Send FAX Mail sends records the exact time the counterparty's fax line received your transmission, along with the receiving number. That documentation shuts down a credible non-receipt argument. It moves any remaining dispute to the contract terms themselves rather than the question of delivery.
The broadcast feature lets you transmit to multiple numbers in a single send. That said, when a contract needs counterpart signatures, you usually circulate it one party at a time to collect each signature, then send the fully executed version back out to everyone. Keep a separate confirmation for each recipient.
A typical contract with its exhibits runs 5 to 20 pages, so the Starter plan at $12.99 a month and 600 pages covers a small business closing several deals monthly. Higher-volume operations can step up to a plan with a larger allowance, and if you ever exceed your limit you move to a bigger plan rather than paying per page. Choosing your fax number costs nothing.
