11 | == Prerequisites ==
12 |
13 | Before you start implementing PayEx Invoice Service the following is required:
14 |
15 | * A sFTP Client
16 | * An agreement that includes PayEx Invoice Service (CUSIN)
17 | * Obtained credentials from PayEx
18 | * A basic understanding of [[file name convention and file format limitations>>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.Cusin.WebHome||anchor="HNameconvention"]]
19 |
20 | Pease contact us if you have any questions on how to get started.
21 |
22 | == Overview ==
23 |
24 | Before getting started, have a look at the high level sequence diagram below, which will help you getting a better understanding of the whole process and the components necessary to implement Invoice Service.
25 |
26 | The invoice process using CUSIN is designed to operate batch-wise where multiple invoices are to be handled and sent to PayEx in a single file.

87 | All main steps of the invoice process are described below. **Please note** that all XML examples below are here primarily for display purposes, to help you get an understanding of the CUSIN file format and to aid you in the implementation.
88 |
89 | If you encounter any problem during implementation, don't hesitate to [[contact us>>mailto:invoice.client@payex.com]].
90 |
91 | == Invoicing ==
92 |
93 | The initial step is to create your [[CUSIN >>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.Cusin.WebHome]]file.
94 |
95 | === Cusin ===
96 |
97 | The first thing you need to do is to create a CUSIN file with extension .XML and UTF-8 encoding. Name it according to the filename convention.
98 |
99 | Head over to our [[technical reference section>>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.Cusin.WebHome]] for a more extensive description of the file format, where you find more information of each element in the XML schema and CUSIN example file.
100 |
101 | **Please note! **If there are multiple invoices to be handled at the same time: do not send one invoice per file. We strongly suggest to batch them together in one single file. This will also speed up the process of creating and distributing the invoices.
102 |
103 | To learn more of how to edit invoice column length and use summary rows, visit the [[Invoice columns section>>url:https://developer.payex.com/xwiki/wiki/developer/view/Main/Invoicing/invoice-service/Invoice%20columns/]].
104 |
105 | (% class="wikigeneratedid" id="HTransferringfilestoPayEx" %)
106 | When you have a complete and validated CUSIN file, you are ready to transfer it to PayEx via sFTP.
107 |
108 | (% class="wikigeneratedid" %)
109 | Upon reception PayEx will process the file and send you a receipt in return. If something went wrong, you will also receive an error log.
110 |
111 | === Receipt ===
112 |
113 | When the CUSIN file, containing one or more activities - is processed a receipt will be created showing numbers of processed customers, numbers of processed invoices and total amount. A receipt is created for each file you send.
114 |
115 | Each activity has their own set of result parameters
116 |
117 | You can view the XSD and a detailed description [[here>>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.Receipt.WebHome]].
118 |
119 | === Error log ===
120 |
121 | If errors are encountered during file processing an errorlog will be created. Errors may refer to insufficient customer information, invoice information or format errors. An error log is created for each file you send.
122 |
123 | The first part displays the processed item itself.
124 |
125 | The second part of the error log displays the response item message element that gives reference back to the processed file.
126 |
127 | You can view the XSD and a detailed description [[here>>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.Errorlog.WebHome]].

130 |
131 | When you have transfered your CUSIN file to PayEx and it has been processed successfully the end result will look similar to the invoice example below.

136 |
137 | == Reports and Accounting ==
138 |
139 | You get response files from PayEx in the from of Bill and Customer Journal.
140 |
141 | === Bill Journal ===
142 |
143 | Bill Journal is the format used to notify changes in invoice status. Entries could relate to events such as a new claim process level, invoices getting closed and newly registered complaints and respites.
144 |
145 | You find the Bill Journal technical reference [[here>>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.BillJournal.WebHome||anchor="HBillJournal"]].
146 |
147 | === Customer Journal ===
148 |
149 | Customer Journal is the format used to notify changes in customer information. Entries could relate to events such as a new legal address, activation/cancellation of consent and customer status changes due to decease.
150 |

152 |
153 | === Accounting Detail ===
154 |
155 | Bookkeeping data is produced on two levels. You get accounting records on the transactional level as well as aggretated in the standardised SIE format type 4.
156 |
157 | Files are exported from PayEx on a daily schedule.
158 |
159 |
160 | **The Accounting Detai**l file describes the accounting records on the transaction level and Includes invoice number, book account, amount, value date, etc.
161 |

163 |
164 |
165 | **The SIE4** **file **describes the accounting records on an aggregated level, that includes total amounts per book account.
166 |
167 | You find the SIE4 technical reference [[here>>doc:Main.Invoicing.invoice-service.Implementation guide.Technical reference.SIE4.WebHome||anchor="HSIE4" style="background-color: rgb(255, 255, 255);"]].
