AMAZON UPLOADER
Amazon sales upload involves using three files from Amazon seller central:
1. Merchant tax GST on demand reports – B2C (MTR-B2C)
2. Merchant tax GST on demand reports – B2B (MTR-B2B)
3. Date range reports (DRR)
Amazon B2C uploader (APP) requirements
We will first discuss upload of B2C files using the Merchant tax GST on demand reports –
B2C and Date range reports.
Creating masters
The APP should create the following masters:
1. Tax master from Zoho Books tax module;
2. Branch master along with their GSTN from Zoho Books
3. Item master from Zoho Books
4. Reporting tag master from Zoho Books
5. Bill from state (all states of India) as per Amazon to branch master as per Zoho Books
mapping
6. Ship from state (all states of India) as per Amazon to branch master as per Zoho
Books mapping
7. Postal code to city mapping (static excel file)
Amazon B2C uploader (APP) requirements
1. Users will download MTR-B2C and DRR and store the same on a local drive or google
drive. The reports downloaded and stored will be cumulative for the month. For
example, on 6 September 2022, the team will download and store MTR-B2C and DRR
from 1 September 2022 to 5 September 2022, then again on 8 September 2022, the
team will download and store MTR-B2C and DRR from 1 September 2022 to 8
September 2022. The reason for doing this is that we have found some entries to
creep into older periods after the reports were downloaded.
2. The APP should pick up MTR-B2C and DRR from the stored location and load into the
APP. The APP should filter for invoices (please remember an invoice can have
multiple invoice items and hence MTR-B2C can have multiple lines against a single
invoice number) marked as ‘Shipment’ from the ‘Transaction Type’ column. Only
invoices marked as ‘Shipment’ should be processed by the APP. The APP should
check if the invoice number has already been posted in Zoho Books. If invoice has
been posted in Zoho Books, the invoice number should be marked as posted along
with the Zoho Invoice ID.

3. The invoices which are not yet posted in Zoho Books should be posted as per the
below mapping:
Merchant tax GST on demand reports –
B2C
Zoho Books
Seller GSTN This should be mapped to the branch
GSTN that is selling the goods
physically.
-NA- Customer name will always be Amazon
(b2C)
Invoice Number Invoice Number
Bill from state Place of supply – We need to ensure
that this is limited to the states against
which branches are created and can be
picked from the ‘Bill from State to
Branch Mapping’. For example, if the
bill from state in the Amazon report is
Gujarat and there is no branch set up in
Gujarat in Zoho Books, the posting
should fail with the preferred error
message ‘Branch not available in Bill
from State’.
Ship from state Source of supply – This is the list of
branches available in the branch master
and can be picked from the ‘Ship from
State to Branch Mapping’. If branch is
not available in ship from state, then
the posting should fail with the
preferred error message ‘Branch not
available in. Ship from State’
Order Number Order Number
Invoice Date Invoice Date
Terms Due on receipt
Ship to postal code Zoho Books invoice module has a
custom city field. The city should be
looked up from the Postal code to city
mapping master file.
-NA- Zoho Books invoice module has a
custom payment type field. The
payment type is available in the
Amazon date range report. The order
ID in the MTR-B2C should be looked up
against the order ID in DRR to obtain
the payment type. If payment type
contains the word ‘Electronic’ then
‘Prepaid’ should be populated as the
payment type else CoD should be

populated as the payment type. If
payment type is not available, then the
posting should fail with the preferred
error message ‘Payment type not
available’.
-NA- Item Rates are ‘Tax Inclusive’
Invoice items SKU This should be populated in the item
details field. Invoice items SKU should
be validated against the item master
SKU. If SKU is not available, then the
posting should fail with preferred error
message ‘SKU not available’. Please
note that in this case if the invoice has
multiple line items and even there one
mismatch then the entire invoice record
should fail.
Invoice item quantity This should be populated in the
quantity field. The APP should check if
quantity is greater than or equal to
inventory quantity in the ‘Source of
Supply’ branch. If there is no inventory
available, then the posting should fail
with preferred error message ’Inventory
not available’. Please note that in this
case if the invoice has multiple line
items and even there one mismatch
then the entire invoice record should
fail.
Invoice amount Rate
Tax rates If bill from state and ship from state is
different, then IGST rates should be
applied else SGST and CGST rates
should apply. The tax rate in the
invoice should be validated against the
tax rate in the item master. For
example, if the MTR-B2C has a tax rate
of 18% for the invoice line item then
SKU in the item master of Zoho Books
should also have 18%. If there is a tax
mismatch, then the posting should fail
with the preferred error message ‘Tax
rate mismatch’. Please note that in this
case if the invoice has multiple line
items and even there one mismatch
then the entire invoice record should
fail.

-NA- Sales channel will always be ‘Amazon.in’
from the reporting tag master. This
should be applied at an invoice line
item level.
