Minimum Payment
Pronunciation: MIH-nuh-mum PAY-munt
Definition
Minimum payment is the smallest amount a merchant, provider, payment method, asset, network, or invoice workflow will accept as one payment.
Overview
How it works and why it matters
A minimum payment is the smallest amount accepted under an asset, network, merchant or provider rule. Minimums can arise from operational costs, decimal precision, dust economics, fraud controls or settlement policy. The applicable floor should be shown before funds are sent.
Practical decision points
Consider three separate minimums before launching checkout. First, the chain or token may impose technical constraints: Bitcoin output dust policies are relay rules, while token contracts may use integer precision. Second, the wallet or provider may set a minimum withdrawal or transfer size to cover operational costs. Third, the merchant may require a minimum invoice value to make fulfillment viable. None of these values can safely be copied from another chain. When pricing microtransactions, compare total customer cost, expected network fee, refund cost and the smallest representable token unit. Define behavior for below-minimum receipts, including whether funds are held for review, credited toward a later payment or refunded when economical.

Example
A customer tries to pay the equivalent of $0.05 on a network with a much higher expected transaction fee. The merchant can decline that route or quote a minimum, but should not silently accept the transaction then refuse to credit it without an established rule.
Comparison
The minimum send amount of a wallet, the blockchain's dust thresholds and a provider's invoice minimum are different constraints.
Key Takeaway
The minimum invoice value may differ from network and wallet transfer thresholds.
