Contract amendment and renewal

How do we amend or renew a business contract with the changes to rates, term or lines drafted from the account, approved internally, signed by the customer and written to billing?

Draft the amendment from the record and route it through the approvals before the customer sees it. Callvu prefills the existing agreement (the term, the rates, the commitments, the lines and sites, the addenda, the renewal date) from the BSS and the contract repository, takes the requested changes (new rates, an extended term, added or removed lines or sites, a new product addendum) from the account team or the customer, computes the commercial effect (the revenue, the commitment, the discount tiers, the early termination exposure), routes the internal approvals in the Decision Desk by the pricing and legal authority matrix, generates the amendment from the approved terms, chases the customer's authorized signer for the signature with their authority checked, and writes the amended terms to the billing system and the contract repository from the effective date, with the renewal clock reset.

The problem today

The renewal was signed on a version with last year's rates, and billing kept charging this year's.

Today, without Callvu

Business contracts change constantly: a rate card renegotiated, a term extended, lines added at a new site, a product addendum. The account manager edits a document from an old template, the pricing approval is an email, legal sees it late, the customer signs a version that does not match what billing was told, and the first invoice after the amendment is a dispute.

An amendment has a source (the agreement as it stands in the repository and the BSS), a commercial effect (the revenue, the commitment, the discount tier, the termination exposure) that the pricing authority must approve, legal terms that legal must approve when they change, a signer on the customer's side whose authority matters, and a billing record that must change on the effective date. Each is a step with an owner; the document should be generated from the approved terms, not edited toward them.

An amendment generated from the approved terms is one billing and the customer read the same way.

How it runs

From the requestto the system of record.

The account team or the customer requests a change to an agreement, or the renewal date approaches. Callvu opens the amendment on the account and prefills the agreement.

Account team: Requests the changes and sees the approvals' status.
Pricing and legal approvers: Approve in the Decision Desk by the authority matrix.
Customer's authorized signer: Reviews and signs on their own screen with authority verified.
Callvu: Prefills, computes, routes approvals, generates, chases the signature and writes.

Prefill and take the changes
The agreement's term, rates, commitments, discount tiers, lines and sites, addenda, signers and renewal date are prefilled from the contract repository and the BSS; the requested changes are taken in a structure (rates by plan, term, lines or sites added or removed, a new addendum, a changed billing arrangement) with the effective date.
Compute and decide the approvals
The commercial effect is computed (the revenue change, the commitment and the tier, the early termination exposure, the margin where the carrier models it) and the changes are classified against the authority matrix; the approvals route in the Decision Desk to the pricing authority and, where terms other than commercial ones change, to legal, each with only the allowed outcomes (approve, approve with changes, decline with the reason).
Generate, chase and verify the signature
The amendment is generated from the approved terms on the current template with the agreement's references, sent to the customer's authorized signer on their own screen with their authority checked against the account's signers (or a resolution chased where the signer is new), and the signature is chased on the schedule with the renewal date in view; a countersignature by the carrier's authorized signer follows.
Write back
The amended terms are written to the billing system from the effective date (the rates, the commitments, the lines and sites, the discount tier), the executed amendment is filed in the contract repository against the agreement with its version, the renewal clock is reset, and the account team and the customer see the same terms.

Where it ends: The amendment was drafted from the agreement, approved by the people the matrix names, signed by a signer whose authority was checked, and written to the billing system, the system of record, on the effective date with the repository holding the executed version. The Decision Trace shows the commercial effect, each approval and the signer's authority; the Audit Trace shows the changes requested, the approvals, the signatures and the write with time.

Runtime enforcement

What is enforcedwhile the work runs.

The regulations preloaded in Callvu Studio and the bank's own policies, applied as steps that run, not lines in a binder. A step that breaks a rule does not run, so a completed run was compliant.

Regulations

The master agreement's amendment and renewal clauses and the carrier's pricing and legal authority matrix: The agreement sets how it may be amended (in writing, signed by both parties' authorized representatives), the renewal mechanics (auto-renewal with notice periods, or renegotiation), and the commitments and the early termination terms; the authority matrix sets who may approve rate changes by margin band, term changes and non-commercial term changes, which the Decision Desk enforces.
FCC truth-in-billing rules (47 CFR 64.2401) and the tariff or the contract's billing terms: The amended rates and charges must be described on the bill as the amendment provides, from the effective date, and the business customer's bill must match the contract terms in the repository.
E-SIGN (15 USC 7001) and the UETA for the electronic amendment: An amendment signed electronically by each party's authorized signer with consent and retained evidence is enforceable; the signer's authority is a matter of the customer's corporate authority which the carrier verifies against the account's signers.

Company policies

The amendment is generated from the approved terms on the current template; nobody edits a document toward approval.
Approvals route by the authority matrix in the Decision Desk before the customer sees the amendment.
The customer's signer's authority is checked before signature.
The billing system and the contract repository are written from the executed amendment on the effective date.

Controls

Prefill from the repository and the BSS.
Structured change capture with effective date.
Commercial effect computation and matrix classification.
Decision Desk approvals by pricing and legal.
Generation from approved terms and verified signatures.
Billing and repository writes with renewal reset.

Clocks and deadlines

Renewal notice: The agreement's notice period before auto-renewal, on the account with the amendment started before it.
Effective date: The billing write applies from it; an amendment signed after it is handled by the policy's catch-up rule.
Signature chase: Reminders to the signer on the schedule before the renewal date.

Questions

What buyers ask next,answered plainly.

Who approves the amendment?

The pricing authority for the commercial effect and legal for non-commercial term changes, by the authority matrix in the Decision Desk, before the customer sees the document.

How is the document produced?

Generated from the approved terms on the current template with the agreement's references, never edited from an old copy.

When does billing change?

From the effective date, written from the executed amendment, with the repository holding the version billing matches.
