The short answer
Three things separate convenience and grocery from general retail. SNAP authorisation depends on meeting USDA's staple food criteria, and a final rule published 8 May 2026 changes the stocking standards for retailers from 4 November 2026. Cash-back at the counter is tightly specified: USD 200, debit and prepaid only, PIN required. And with small baskets, the per-transaction fee drives the bill far more than the percentage does. General information on card network rules, not legal advice (September 17, 2026).
SNAP authorisation: Criterion A or Criterion B
To be authorised as a SNAP retailer, a store must meet one of two tests. Criterion A is staple food inventory: a minimum of 36 staple food items, made up of three varieties in each of the four staple food categories, three stocking units for each of those varieties, and one perishable variety in two of the categories — and USDA notes the shelves must carry these items on a continuous basis, not just on inspection day. The four staple categories are vegetables or fruits; dairy products; meat, poultry or fish; and breads or cereals. Staple foods do not include prepared or heated foods or accessory foods. Criterion B is staple food sales: staple foods must make up more than half of the store's total gross retail sales, which is how specialty stores such as butchers and produce stands usually qualify. USDA also applies a restaurant test — a firm counts as a restaurant, and generally cannot redeem SNAP benefits, if more than 50% of total gross retail sales come from hot or cold prepared foods intended for immediate consumption — and a need-for-access consideration for stores that meet neither criterion but serve an area with very limited food access.
The November 2026 stocking change
This is the date to put in the diary. USDA's store eligibility page carries a notice that on 8 May 2026 it published the final rule "Updated Staple Food Stocking Standards for Retailers in SNAP", that the rule makes several changes to retailer stocking requirements, and that retailers must comply starting 4 November 2026. USDA says it will update its retailer training pages with guidance and update the eligibility page as appropriate — which means the criteria described above are the current standard but not necessarily the standard that applies after that date. If EBT volume matters to your store, the correct action now is to watch the FNS retailer training page for the updated guidance rather than to assume today's 36-item arithmetic carries over unchanged.
What EBT cannot buy, and why that is a POS configuration problem
SNAP covers food for the household, including fruit and vegetables, meat, poultry and fish, dairy, breads and cereals, other foods such as snacks and non-alcoholic beverages, and seeds and plants that produce food for the household. It cannot be used for beer, wine and liquor; cigarettes and tobacco; food and drinks containing controlled substances such as cannabis or CBD; vitamins, medicines and supplements — USDA gives a clean test here, that if an item carries a Supplement Facts label it is a supplement and is not eligible; live animals, except shellfish, fish removed from water, and animals slaughtered before pick-up; foods that are hot at the point of sale; and non-food items including pet food, cleaning and paper products, and hygiene items and cosmetics. Every one of those lines is an item-level flag in your POS. A convenience store with a loose item catalogue cannot enforce them at the till, which makes the catalogue work an EBT compliance task as much as an inventory task.
Cash-back: the rules people get wrong
Cash-back is a genuine draw for a convenience store, and it is closely specified. In the US, Visa's rules permit cash-back with or without a purchase, cap it at USD 200, and limit it to debit and prepaid cards. The general requirements apply on top: the transaction must be authorised online, completed as a retail transaction in a face-to-face environment, and contain a PIN — in the US region, specifically a PIN. The cash-back portion of the amount must be uniquely identified, and the transaction processed in the merchant's local currency. No credit refund or credit transaction receipt may be processed for the cash-back component, so a returned item does not unwind the cash. All acquirers, issuers and merchants must participate in the Partial Authorization Service, and a partially approved amount must not be applied to the cash-back portion — which is the rule that stops a partial approval quietly turning into a short till. Merchants may set a lower cash-back limit than USD 200 at their discretion. Note also the general prohibition: a merchant must not provide cash to a cardholder at all except as cash-back, cash-out or a foreign currency sale, and a prepaid card must not be redeemed for cash by a merchant that accepts it.
Minimums do not solve the small-basket problem
The instinct at a $9 average basket is to set a card minimum. Federal law at 15 U.S.C. 1693o-2(b)(3) and Visa's rules allow one, but the boundaries limit its usefulness here: the maximum is USD 10, it applies to credit cards only, and it must not discriminate between issuers or between Visa and another network. Since convenience and grocery run heavy debit volume, a credit-only minimum leaves most of the small-basket traffic untouched. It is worth knowing the rule; it is not a pricing strategy.
Why the per-item fee decides the bill
With small baskets and high transaction counts, the fixed per-transaction component dominates. Illustrative example with made-up round numbers, not a quote: on a $9 basket, a plan priced at 2.4% + $0.10 costs 31.6 cents while a plan at 2.9% + $0.04 costs 30.1 cents — the higher percentage is the cheaper plan at that ticket, and the crossover moves as the basket changes. Which is why the only useful comparison for this format is total cost per basket at your actual average ticket and your actual debit mix, not a headline rate. Ask for debit to be priced separately and per item, ask what your average ticket has to be before the ranking of two quotes flips, and get the structure in writing with an effective date. We are an independent agent, not a processor, and processor-set fees are exactly that — set by the processor — so the number to negotiate is the structure and the markup, not a figure we could quote you here.
Key takeaways
- SNAP authorisation runs on Criterion A (36 staple items, stocked continuously) or Criterion B (staple foods over 50% of gross retail sales)
- A final rule published 8 May 2026 changes retailer stocking standards from 4 November 2026 — watch the FNS retailer training page
- If an item carries a Supplement Facts label, USDA treats it as a supplement and it is not SNAP-eligible
- US cash-back is capped at USD 200, debit and prepaid only, PIN and online authorisation required, and it cannot be refunded
- A card minimum is capped at USD 10 and applies to credit only, so it barely touches a debit-heavy small-basket store
- Compare quotes on total cost per basket at your real average ticket, not on the percentage
