Haravan → MeInvoice — automatic e-invoices, multi-MST via V2

Haravan shops need MeInvoice e-invoices when orders are placed — no manual copying. GenNova Dev creates invoices, updates status and lookup codes when conditions are met. On failure, the system logs and supports retry.

Haravan shops need MeInvoice e-invoices when orders are placed — no manual copying. GenNova Dev creates invoices, updates status and lookup codes when conditions are met. On failure, the system logs and supports retry.

Multi-entity businesses use Haravan → MeInvoice V2 (AIO): one shop connects to multiple MeInvoice accounts (multiple tax IDs), each with its own token and invoice templates. Set a default MST and assign MST per branch, sales channel or storefront via sub-mapping — ideal for groups, franchises or multi-brand shops.

FAQ

Are MeInvoice e-invoices created automatically from Haravan orders?

Yes. When an order meets configured conditions, the system issues an e-invoice and updates the lookup code.

How are invoice issuance errors handled?

Detailed logs per order, manual or bulk retry support and alerts on failure.

How is MeInvoice V2 (AIO) different?

V2 uses the new MeInvoice API with draft → publish on one platform, better logs and retries.

Invoices for returns / refunds?

Configurable by order type; conditions set in the MeInvoice dashboard.

Is AMIS connection required?

Not required for e-invoice issuance; product/customer cache from AMIS can be used if connected.

Can one Haravan shop issue e-invoices for multiple tax IDs (MST)?

Yes — via Haravan → MeInvoice V2 (AIO). Add multiple MeInvoice accounts (one MST per row), set a default MST and assign MST per branch / channel / storefront through sub-mapping.
