Hi Guys,
I'm trying to send an item (service type) to the Reckon account Hosted though RAH API, I send the price for this item. i.e 200.00 AUD. Then I send a sale receipt for a contact and this item. This contact made a payment 220.00 AUD (amount include GST) on our website and we send 220.00 in the amount field to the Reckon. Reckon added 22.00 AUD again as a GST to the Sale receipt and I can see 242.00 as a total. See the screen shot not 220.00

How can I send this recipe as amount 220.00 but still total be 220.00, not 242.00?
There is an option in the Sale receipt to tick this amount include GST. When I log in to the Reckon and ticked this one, the amount jumps to 242.00.

How can I fix it and say to Reckon API this amount is included tax, don't add tax to it again?
I really appreciate your help.
Thanks,
