Introduction

a3ERP is an enterprise resource planning (ERP) software for small and medium enterprises in Spain, unifying accounting, invoicing, sales, inventory, CRM, and payroll on one platform. It runs on the client’s own server, and the Chift connector reaches it through a local agent installed there.

Connector settings

The Invoice creation type setting in the Chift connector settings, with its options Accounting Invoices and Normal Invoices
Invoice creation type chooses whether Chift creates normal invoices or accounting invoices in a3ERP.
  • Accounting Invoices (default): Chift creates accounting invoices. They cannot be sent or printed from a3ERP.
  • Normal Invoices: Chift creates normal invoices.
Choose Normal Invoices if you need to send or print the invoices from a3ERP.
The AEAT operation type mode setting in the Chift connector settings, with its two options: derived from the customer or supplier, or specified per invoice with extended VAT codes
AEAT operation type mode determines how a3ERP’s AEAT operation type, the régimen de IVA, is set on invoices.
  • AEAT operation type is derived from the customer/supplier linked to the invoice (default): the operation type comes from the customer or supplier on the invoice.
  • Specify the AEAT operation type per invoice (extended VAT codes): you set the operation type on each invoice.
Choose the second option to set the operation type per invoice. Without it, the operation type always follows the partner’s default. With extended VAT codes, Chift lists one variant of each a3ERP VAT code per compatible operation type. Each variant is typed purchase or sale, and nothing is created in a3ERP. Send the variant as the line’s tax code, in this format: <code>_<operation type>.

Local agent guide

Installing and running the local agent.
Before they start, your end users need:
  • a3ERP version 14.5.2 or later, with .NET Framework 4.8 installed on the server running a3ERP
  • an a3ERP user and password with access to the company they want to connect
  • a Windows admin account, to install the local agent on the a3ERP server
  • the local agent installed on the same server as a3ERP, not on another machine
  • if a3ERP data sits on a network drive, the A3ERPService Windows service running under an account with access to that drive
To connect, they:
  1. Enter their a3ERP username and password. If the form shows them, they also choose the default analytic plan, the invoice creation type and the AEAT operation type mode.
  2. Download the installer, or have it emailed to whoever performs the installation.
  3. Specify the company code of the a3ERP entity to connect. The code is shown on a3ERP’s company selection screen, the first screen a3ERP displays.
  4. Run the installer on the a3ERP server.

​
Limitations & specificities

Invoice numbers can only contain digits.
  • Journal entries can only be posted to a3ERP journals, the diarios. Chift returns them with type miscellaneous_operation.
  • The customer and supplier journals that stand for a3ERP invoice series cannot receive journal entries.
  • A line on an employee account is rejected.
Rules on the AEAT operation type, the régimen de IVA. Otherwise, a3ERP rejects the invoice:
  • All lines of an invoice use the same operation type, since a3ERP carries it at the invoice header level.
  • With a reverse-charge operation type, the VAT amount is 0.
  • When AEAT operation type mode is set to extended VAT codes, the operation type matches the invoice: a purchase type on a supplier invoice, a sales type on a customer invoice.
Not supported: each connection covers a single a3ERP company, chosen by its company code when connecting.
