Convenience Stores, C-Stores Industry Terminology

ACV (All Commodity Volume)

A weighted distribution metric that reflects the total retail sales volume of all stores where a product is available; used to gauge reach and prioritize distribution and promotions in the channel.

Examples: 'Our launch hit 75% ACV in the c-store channel.' 'Prioritize chains with higher ACV to maximize trial.' 'The brand’s ACV-weighted velocity is outperforming category benchmarks.'

Age Verification

The process and tools (e.g., ID scanning, prompts at POS) used to confirm a customer meets legal age requirements for regulated items such as tobacco, vape, alcohol, and lottery.

Examples: 'Scan every ID for tobacco to ensure T21 compliance.' 'Install ID scanners at self-checkout to automate age verification.' 'Mystery shops will test our age verification process this month.'

Average Basket Size

The average dollar value per transaction, typically for inside (non-fuel) sales; calculated as total inside sales divided by number of inside transactions.

Examples: 'We lifted average basket size from $8.90 to $9.45 with meal bundles.' 'Exclude fuel when calculating inside average basket size.' 'Loyalty members have a 15% higher average basket.'

Backbar
