--- title: "ERP integration: Odoo, SAP and Business Central | attendo" description: "Native connectors for Odoo, SAP Business One, Business Central and Holded. Your ERP issues the invoice with its numbering, and each connector is tested first." url: "https://attendo.me/en/modules/erp-integrations" lang: "en" --- # Operations in attendo. Accounting in your ERP. Customers, items, quotes, delivery notes and hours flow between attendo and your ERP without retyping. The invoice is issued by your connected ERP, with its official numbering: attendo is not an ERP or accounting software. - You choose what syncs - Tested in your test environment - Queue with retries if the ERP goes down ## ERP integrations: what it does ### The invoice, in your ERP attendo prepares what is billable and your ERP issues the invoice with its official numbering, which comes back to attendo on its own. No one types the invoice twice. ### Odoo, both ways Customers, contacts and suppliers go back and forth. Products and price lists come from Odoo. Quotes, delivery notes and hours go to Odoo. And the sales rep’s tasks travel as activities, with their status. ### Business Central, SAP and Holded With Microsoft Dynamics 365 Business Central, customers, contacts, items, sales documents and hours sync. With SAP Business One, business partners, items and sales documents. With Holded, contacts, products, quotes and delivery notes. ### You choose what syncs Turn areas on one by one: customers, catalog, stock, documents and payments. In Odoo and SAP Business One you mark which records sync. If you uncheck one and check it again, it picks up where it left off, without duplicates. ### From the document’s record Send the document to the ERP and lock it, recalculate its amounts or print your ERP’s PDF without leaving the record. And when it is accepted, invoiced or voided, the ERP is notified. ### If your ERP is not listed API v4, a REST API with key-based permissions, and outgoing webhooks with history and resend. An ERP that is not on the list can receive delivery notes by webhook. If that is not enough, the connector is built as a project. ## Step by step This is how it is used day to day, on the same document as the rest of the modules. ### Step 1 · Mapping session Together with your team, we agree on series, taxes, payment methods, products and which areas sync. ### Step 2 · Test in your test environment The connector is validated against your ERP’s test environment. Nothing touches the live ERP until it works. ### Step 3 · Match what already exists The existing records in both systems are matched, so no customer or item ends up duplicated. ### Step 4 · Live, with a safety net Changes are queued with retries, and the monitor shows what has synced. If the ERP goes down, they wait and are applied when it comes back. ## It fits every area Industry solutions [attendo CRM](https://attendo.me/en/crm) [attendo CMMS](https://attendo.me/en/cmms) [attendo Field Service](https://attendo.me/en/field-service) [attendo After-Sales](https://attendo.me/en/after-sales-service) [attendo Projects](https://attendo.me/en/projects) [attendo Flows](https://attendo.me/en/flows) ### Industries that use it - [Manufacturing and industrial plants](https://attendo.me/en/industries/manufacturing): The spare part, located and on time - [Equipment manufacturers and distributors](https://attendo.me/en/industries/equipment-manufacturers): A CRM that knows what you sell - [And any other business](https://attendo.me/en/industries): attendo can be set up for any line of business.

Mapping series, taxes and products takes a session with your team, and with SAP Business One, with your SAP consultant. - With Holded, it does not cover the projects, POS or HR add-ons. With SAP Business One, it does not cover production, MRP or cost accounting. - In Odoo, if a customer changes in both systems at the same time, attendo’s data wins and the change is logged. ## Modules that go hand in hand ### [Business documents](https://attendo.me/en/modules/business-documents) Quotes, orders and delivery notes in sequence; invoices in your ERP ### [Quote management and web quotes](https://attendo.me/en/modules/quotes-and-web-offers) Quotes with options that the customer opens, picks and accepts ### [attendo Pay](https://attendo.me/en/modules/pay) Collect deposits and payments online through your own gateway ### [attendo Flows, Business Process Flow (BPF) and AI-Flows](https://attendo.me/en/modules/flows) Flows, phased processes with approvals, and AI inside the flow ## Glossary terms Sales and customers ### Customer profitability Account profitability Customer profitability is the difference between what you bill an account and what it costs you to serve it. Maintenance ### Critical spare part Critical spare A critical spare part is one whose absence holds up the repair and drags out the equipment’s downtime. It is not the most expensive part or the most used one: it is the one you cannot get quickly. Maintenance ### CMMS Computerized maintenance management system A CMMS (computerized maintenance management system) is the software where an organization records its assets, plans maintenance, manages work orders and keeps track of spare parts and costs. Sales and customers ### Deposit Upfront payment · down payment · advance payment A deposit is the part of the price a customer pays up front, when accepting the quote or before the work starts, and it is then deducted from the total.

No. The invoice is still issued by your connected ERP, with its official numbering: attendo is not an ERP or accounting software. attendo passes it what is billable, and your ERP handles tax filings (in Spain, SII and the other obligations with the AEAT). ### I use Odoo. Who sends the quote? attendo, with its web quote, signature, deposit and your branding, and the order is marked as sent in Odoo. If you prefer Odoo to send it, that is chosen per document type, but that email does not include the web quote link. ### What if the ERP goes down? Changes wait in the queue and are applied when it comes back. The connector monitor shows what was left pending and lets you retry it. ### Do product codes get overwritten? No. The ERP code, the SKU and several barcodes coexist with your internal code without overwriting it. ### My ERP is not on the list. It connects through API v4, with key-based permissions, or through webhooks. If that is not enough, the connector is built as a project and tested just like the others. ## Try it with your processes We will show it to you with your own document types and the way you work.
