It is not affiliated with, endorsed by or sponsored by Registrite ja Infosüsteemide Keskus (RIK), the operator of e- Financials / e-Arveldaja, nor by Automattic, the owner of the WooCommerce trademark.“ e-Financials”, “e-Arveldaja” and “WooCommerce” are used here only to describe what this plugin connects to. Background sync so checkout stays fast. Once an order is paid (or marked completed) the plugin: 1. Upserts the customer as an e-Financials client. 2. Ensures every ordered product exists as an e-Financials product. 3. Creates and registers the sale invoice. 4. Records the payment (cash fields and/or a bank transaction), gateway-agnostic. 5. Optionally delivers the invoice to the customer by email or e-invoice. 6. Issues credit invoices on full and partial refunds. Merchants get a settings screen, an order list column, an order metabox with the invoice PDF, manual order actions and an optional note on customer emails. The plugin is compatible with WooCommerce High-Performance Order Storage (HPOS) and queues its work through Action Scheduler, so no API call ever blocks a shopper. #### External service: e-Financials (e-Arveldaja) This plugin is an interface to **e-Financials / e-Arveldaja**, the accounting service operated by Registrite ja Infosüsteemide Keskus (RIK), an Estonian government agency. It is not affiliated with or endorsed by RIK. The plugin sends no data anywhere until you enter your own e-Financials API credentials on the settings screen. Once configured, it contacts RIK’s API at `https://rmp- api.rik.ee` (live) or https://demo-rmp-api.rik.ee (test environment), depending on the environment you select. Data sent to that service, only for orders your shop processes: * Billing name, company name, e-mail address, phone number, postal address and country. * VAT / registry number, when your shop collects one. * Order line items: product names, SKUs, quantities, prices, VAT rates, shipping and fee lines. * Order number, order date, payment method identifier and payment amounts. * Refund amounts and reasons, when you issue a refund. Data received from that service: client, product, invoice and transaction identifiers, invoice numbers and invoice PDFs, plus the option lists (invoice series, templates, sale articles, cash accounts) shown on the settings screen. If you enable invoice delivery, RIK’s service sends the invoice e-mail or e-invoice to your customer on your behalf. Using the service requires an agreement with RIK.

Choose the test environment on the settings screen to point the plugin at e- Financials’ demo API and try the sync without touching live books. ### Are prices and VAT taken from the shop? Yes. VAT rates come from the order lines and are mapped to e-Financials sale articles, which is how e-Financials books VAT. Every rate used by the shop needs an entry in the VAT rate map. ### Is the plugin free to use in production? Yes. It is free software under GPLv2 or later, with no restriction on production use, company size or revenue, and no feature is locked behind a payment. Updates are delivered through WordPress.org like any other plugin here. Paid subscriptions, offered separately, cover support and consulting only — never permission to run the plugin or access to extra functionality. ### Is this an official RIK product? No. It is an independent integration built against the public e-Financials REST API, and is not affiliated with or endorsed by Registrite ja Infosüsteemide Keskus. ### Does the plugin work with High-Performance Order Storage? Yes. The plugin declares HPOS compatibility and reads and writes order data through the WooCommerce CRUD API, so it works with both the legacy post storage and HPOS. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Arbictus Sync for e-Arveldaja” is open source software.

Sync data stored by earlier versions is not carried over. * Fix: the plugin no longer writes a compiled container into its own directory, which failed on read-only installs. #### 1.0.3 * Fix: two sync runs for the same order could both proceed at once and register a duplicate invoice; the sync lock is now claimed atomically in the database. * The bundled e-Financials PHP client is updated to 1.0.0. #### 1.0.2 * The plugin is renamed to “Arbictus Sync for e-Arveldaja”. * The bundled Guzzle HTTP client is updated to 8.2, which defaults HTTPS connections to TLS 1.2 or newer. #### 1.0.1 * The accounts dimension and cash account settings are now dropdowns loaded from e-Financials instead of raw ID fields. * Every active account is offered for the cash account, with cash and bank accounts grouped first; dimensions are grouped by their account. * All dropdowns loaded from e-Financials are searchable by account number, name and IBAN. * Fix: saving settings while e-Financials was unreachable, or with a saved ID missing from the fetched list, cleared that ID and could silently switch off payment recording. #### 1.0.0 * Initial release. ## Meta * Version **1.1.1** * Last updated **1 day ago** * Active installations **Fewer than 10** * WordPress version ** 6.5 or higher ** * Tested up to **7.1.2** * PHP version ** 8.2 or higher ** * Tags * [Accounting](https://wordpress.org/plugins/tags/accounting/)[Bookkeeping](https://wordpress.org/plugins/tags/bookkeeping/) [estonia](https://wordpress.org/plugins/tags/estonia/)[invoices](https://wordpress.org/plugins/tags/invoices/) * [Advanced View](https://wordpress.org/plugins/arbictus-sync-for-e-arveldaja/advanced/) ## Ratings No reviews have been submitted yet.
