An amendment is a change to an active subscription or contract before its term ends, such as adding or removing quantity, swapping a product, changing the price or extending the term.
A worked example
Example, with made-up numbers: a customer has a 12-month contract for 100 seats at $1,200 per seat per year, starting 1 January. On 1 July they add 20 seats. The amendment co-terms the 20 seats to 31 December, so the first charge covers six months: 20 × $1,200 × 6 ÷ 12 = $12,000. Contract ARR rises from $120,000 to $144,000, and the value of this contract year rises from $120,000 to $132,000. The renewal opportunity, updated by the same amendment, is now for 120 seats at $144,000 before any uplift. Four things changed from one order: the invoice, the subscriptions, the contract roll-ups and the renewal.
Where amendments go wrong
The most common failure is a renewal that never hears about the amendment, so next year's quote offers last year's 100 seats. The second is re-keying the change into a separate billing tool, where it drifts from the CRM. The third is deciding case by case: write down which changes are allowed mid-term, which proration method applies, and whether a reduction earns a credit now or takes effect at renewal. The six amendment types and the arithmetic are in subscription amendments explained.
In Salesforce
Standard Salesforce has Contract, Order and Asset objects but no subscription object and no amendment logic: editing a Contract doesn't reprice anything, prorate an invoice or touch the renewal. That logic comes from an app. Salesforce CPQ amends from the Contract, which opens an amendment quote; changes are expressed as new quote lines for the difference and co-termed to the contract end date. Revenue Cloud Advanced makes amendments asset-based, with AssetStatePeriod recording each span of consistent quantity, amount and MRR. Under ASC 606 an amendment is a contract modification, and how it is recognized is a call for finance.
How Kugamon handles it
In Kugamon Subscription Management (kuga_sub), a mid-term addition is an Expansion: an Expansion Opportunity, Quote and Order tied to the existing Contract, started from Manage Contracts or from the Contract itself. Previously purchased Assets and Subscriptions can be added at their original Purchase Price. Kugamon co-terms and prorates every added line to the Contract End Date; releasing the Order updates the Contract, adds the Subscriptions and Assets, and updates the Renewal Opportunity. Dropping a line runs through [Cancel Subscription], which decrements or removes it from the Renewal Opportunity, and a partial cancellation can be noted on the Invoice with an Additional Charge/Credit.
