Vendor Catalog Batch
====================

**Batch Type Key:** ``vendor_catalog``

**Purpose:** Allows updating product costs from new catalog data

**Default Handler:** :class:`~rattail:rattail.batch.vendorcatalog.VendorCatalogHandler`

Data for this type of batch usually comes from a spreadsheet or
similar file, as obtained directly from the vendor.  You can also
define a "common" format to use, in which case you would convert each
vendor file to that format.  (That is to cut down on the number of
file parsers needed.)

In any case executing this batch will just update Rattail by default;
you may want a custom handler to update your POS system instead.
