Five things set a Philippine store's Shopify set-up apart, and all five belong in the first scoping call.
No Shopify Payments. Shopify's own payment processing isn't open to Philippine businesses. Checkout has to be wired to a third-party payment provider of your choosing, and that choice decides which payment methods customers see, how refunds work and when money reaches your account. Ask your expert which providers they've connected for stores here and what testing they run before launch. If payments are the whole job, payment gateway specialists are a narrower hire.
Pesos, set before anything else. The store currency is the Philippine peso (PHP). Confirm it before importing products, because the currency drives how every price is entered.
Till hardware means a retailer, not Shopify. Shopify won't ship devices from its hardware store to the Philippines. It points merchants here to third-party retailers instead, so an expert setting up a shop counter should confirm each card reader, printer and scanner is a supported model before you buy.
Tax is entered by hand. Manual Tax is the only option here: no Shopify Tax, no Basic Tax. You or your expert set the rates, decide which products and shipping charges are taxed, and update them when rules change. Third-party tax apps are allowed too. Ask for the settings to be checked against your accountant's advice, not guessed.
English admin and checkout. Shopify supports English for both and Filipino for neither. Plan storefront copy in English, and treat any Filipino content as a theme and copywriting job.
