 Have a look at the models in `lib/xeroizer/models/` to see the valid attributes, associations and 
 minimum validation requirements for each of the record types.
 
+### Bulk Creates & Updates
+
+Xero has a hard daily limit on the number of API requests you can make (currently 1,000 requests
+per account per day). To save on requests, you can batch creates and updates into a single PUT or
+POST call, like so:
+
+```ruby
+contact1 = xero.Contact.create(some_attributes)
+xero.Contact.batch_save do
+  contact1.email_address = "[e-mail]"
+  contact2 = xero.Contact.build(some_other_attributes)
+  contact3 = xero.Contact.build(some_more_attributes)
+end
+```
+
+`batch_save` will issue one PUT request for every 2,000 unsaved records built within its block, and one
+POST request for evert 2,000 existing records that have been altered within its block. If any of the
+unsaved records aren't valid, it'll return `false` before sending anything across the wire;
+otherwise, it returns `true`. `batch_save` takes one optional argument: the number of records to
+create/update per request. (Defaults to 2,000.)
