1C:Accounting Integration with Website
1C:Accounting is an accounting system for maintaining accounting and tax records. Integration with a website allows automatic generation of primary documents (invoices, shipping bills, acts) from online store orders and transmission of payment data.
Key Integration Tasks
- Order transmission → creation of sales and invoices in 1C
- Payment synchronization: money received on website → cash receipt in 1C
- Nomenclature export: product directory from 1C → website catalog
- Counterparty synchronization: website buyers → 1C clients
Technical Connection Options
HTTP Service in 1C:Accounting — an HTTP request handler is created in the configuration. A REST endpoint is published through the 1C web server. The website accesses it with JWT authorization.
External Handlers and COM Connection — a 1C agent on the same server as 1C interacts through COM object COMConnector. More performant but requires Windows server.
Creating Product Sales
// Structure of a request to 1C HTTP service
$payload = [
'OperationType' => 'SalesCreation',
'OrderNumber' => $order->id,
'Date' => $order->created_at->format('d.m.Y'),
'Organization' => 'OOO "Shop"',
'Counterparty' => [
'Name' => $order->customer_name,
'TIN' => $order->customer_inn,
'Email' => $order->customer_email
],
'Goods' => $order->items->map(fn($item) => [
'Article' => $item->sku,
'Quantity' => $item->quantity,
'Price' => $item->unit_price / 100,
'VATRate' => '20%'
])->toArray()
];
Invoice for Legal Entities
Legal entities often request an invoice before payment. The website requests a PDF invoice from 1C:
$invoice = Http::post("{$this->baseUrl}/invoice/create", [
'order_id' => $order->id,
'customer' => ['inn' => $inn, 'kpp' => $kpp, 'company' => $company]
]);
$pdfUrl = $invoice['pdf_url'];
// Save link, send to buyer
Nomenclature Directory Synchronization
Nomenclature from 1C:Accounting is a basic product directory. Exported via XML exchange or direct HTTP service request. Frequency: every hour for prices, daily for names and characteristics.
Configuration Features
1C:Accounting exists in several editions (2.0, 3.0) and can be significantly customized. Before starting integration, you must obtain from the client:
- 1C platform version and configuration edition
- Schema of used objects (which directories and documents are involved)
- API user rights for reading/writing needed objects
Development Timeline: 4–7 weeks depending on 1C configuration complexity and data volume.
