Sigma — Vera ⇄ your ERP
Sigma connects Vera with your ERP (SAP S/4HANA, SuperFaktúra): master data, orders and invoices with no re-typing. A 1.0 draft today; price on request.
Sigma draft 1.0
The mark
The right-hand column is one tall tile instead of two. Sigma joins the ERP to everything else, and that is what joining means: two become one.
What is Sigma?
In a larger company, products, stock and invoices live in the ERP and the e-shop is a second world next to it. Somebody then re-types orders from e-mail into SAP and invoices back again. Sigma is the integration between Vera and the ERP: master data flows from the ERP into Vera, orders from Vera into the ERP and invoices back, with no re-typing. When another client joins, the connector changes, not the website. Today Sigma is at the 1.0 draft stage and the first Vera ⇄ SAP connection is being prepared for a client. It is not on the price list yet; the price is on request.

What Sigma connects
-
Master data
Products, prices and stock come from the ERP. Nobody creates them a second time in Vera, and they never drift apart.
-
Orders
An order from the e-shop goes straight into the ERP. No more re-typing from e-mail into SAP.
-
Invoices
An invoice issued in the ERP comes back to the order in Vera, so both you and the customer have everything in one place.
-
Reliable operation
Every message is delivered exactly once (idempotency and an outbox) and products are matched through SKU mapping. An ERP outage does not mean a lost order.
Connectors
Which ERP systems
- SAP S/4HANA
- SuperFaktúra
Others by agreement — the connector changes, not the website.
Honestly, where it stands
Today Sigma is a 1.0 draft, not a finished product on the price list. The first Vera ⇄ SAP connection is being prepared for a client. If you run an ERP and want it connected to your e-shop, write to us and we will tell you what it would involve for you.
Sigma and Vera
Sigma stands on Vera: without it there is nothing to connect, because the e-shop, the catalogue and the orders all live in Vera. Take a look at Vera first.
