Is an electronic signature legally binding?

Yes. Electronic signatures generally form legally binding records under the federal ESIGN Act (15 U.S.C. ch. 96) and state UETA laws. Certain exceptions apply (wills, some court filings). For intrastate variations consult state law before execution.

When is notarization or witness required?

Notarization needs vary by state and by document type. Financial addenda rarely require witnesses but may need notarization for certain authorities or attachments; verify state notary statutes or use Remote Online Notarization where available under state law.

Can I e-sign a financial addendum?

Yes, if the parties consent and the record can be retained and reproduced. ESIGN (15 U.S.C. §7001) and UETA authorize e-signatures; exceptions such as wills and some court filings remain. Consumer-facing disclosures may be required.

What happens if names mismatch?

Name mismatches between the addendum and tax records can trigger TIN validation failures, backup withholding at 24%, and delays in vendor setup. Correct names or obtain documentation to reconcile identities before submitting.

How long must I retain signed addenda?

Retain signed Financial Subscriber Addenda per applicable rules: at least three years for tax purposes (IRC §6501(a)), six years for HIPAA-covered health records (45 CFR §164.530(j)), and longer if industry or state rules require it.

How to correct errors after signing?

Execute a written amendment signed by authorized parties referencing the original addendum, or issue a credit memo and revised invoice. Do not alter the signed original; document any corrections through formal amendment or mutually executed addendum.

What the Financial Subscriber Addendum Is

The Financial Subscriber Addendum is an addendum to a master services agreement or subscription contract that documents specific financial terms, payment authorizations, and billing responsibilities between a vendor and a subscribing organization. It clarifies invoicing schedules, fee calculations, payment methods, late-payment remedies, and responsibility for taxes or third-party charges. The addendum also records delegated approval authorities and any escrow or reserve requirements tied to the subscription. Use this document to ensure both parties' accounting teams share a single source of truth for payment timing, dispute resolution, and post-termination financial reconciliation procedures.

Why a Financial Subscriber Addendum Matters

Use the Financial Subscriber Addendum to reduce billing disputes, document delegated payment authority, and set clear remedies for late or missed payments. It improves auditability by aligning invoicing terms with accounting controls and establishes the contract terms needed for compliant electronic recordkeeping.

Who Completes the Addendum and How They Work Together

Parties typically include the vendor, the subscribing organization, and financial officers responsible for invoicing, payments, and reconciliation.

Procurement and accounts payable teams that approve invoices and manage vendor payment timelines.
Vendor finance or billing contacts who set fees, report charges, and handle disputes.
Legal or contract administrators who ensure the addendum aligns with master agreement provisions.

Ensure signatory officers and finance contacts review the addendum before execution to avoid later conflicts.

Tax & Withholding

Allocate responsibility for sales, use, VAT, and withholding taxes; require remittance evidence and specify who bears penalties for incorrect tax treatment, including backup withholding due to missing taxpayer identification.
