What is net terms acceleration in a service contract?

An acceleration clause allows a creditor to 'accelerate' the due date of future payments to the present if the debtor defaults. In a service context, if a customer is on a payment plan or net-90 terms and they miss their payment, the acceleration clause makes the full outstanding balance due immediately — rather than waiting for each installment or future invoice to come due on its normal schedule. This gives the creditor grounds to take immediate collection action without waiting out the full payment schedule.

Acceleration clauses are most relevant in two scenarios: payment plans for past-due balances (where the customer agreed to pay over time and then stopped), and large ongoing service contracts with extended payment terms. For smaller invoices under net-30 terms, the concept is less relevant because the entire amount is already due within 30 days.

Including an acceleration clause in a service agreement is a standard practice, but enforcing it requires the clause to be clearly written and the customer to have signed the agreement. Verbal agreements with acceleration clauses are difficult to enforce. If your standard engagement letter doesn't include one, adding it to future contracts is straightforward — but it cannot retroactively apply to existing agreements. Not legal advice; have an attorney review any acceleration clause before relying on it in a dispute.
