FAQ
DutyCalc and DutyCode: common questions
- Is DutyCalc or DutyCode cheaper?
- Only DutyCalc lists a free plan. Shoplist compares base prices only between monthly plans in the same currency; usage charges and annual plans vary, so check each plan’s limits.
- What features does each app list that the other doesn’t?
- DutyCalc lists 1 the others don’t mention, such as Tax rates. DutyCode lists 1 the others don’t mention, such as Data export. A feature missing from a listing may still be supported; this compares what each App Store listing says.
- Where does this comparison’s data come from?
- Shoplist crawls Shopify storefronts to detect which apps each store runs, and reads each app’s Shopify App Store listing for reviews, pricing, features and integrations. Store counts are as of Oct 13, 2026 for DutyCalc, Oct 14, 2026 for DutyCode; estimated figures are labeled.
How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026 for DutyCalc, Oct 14, 2026 for DutyCode. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
