Plugins
The core does one thing: it takes the feed and puts it into the store. Everything on top — markup and discounts, photo processing, value replacements, marketplace feeds, meta tags — is a plugin. Each is switched on separately, and the program menu does not grow with their number.

Writing your own
Work to order
The eight plugins above are the ones people asked for often enough to be worth keeping. Anything else we write to your requirements — the core is built for exactly that, and the source is open, so nothing is closed off.
A feed so unusual that a general parser cannot read it: its own field names, prices in a separate file, stock behind another link.
Anything that is not XML, YML, CSV or Excel. JSON from an API, a feed behind a token, a 1C export.
A feed for a marketplace, a price list for a partner, a file for accounting — built from your prices after markup.
Rounding by your rules, competitor-based prices, a separate price for wholesale customers.
If the store is self-written, the program can be taught to write into its tables the same way it writes into OpenCart.
Carrying products, categories and mappings over from whatever kept the store up to date before.
