E-commerce CRM for online stores: from order to repeat purchase
Every buyer gets one card with invoices, payments, shipments and support tickets. CRMiUS connects to your shop through the REST API and webhooks and takes online payments through Stripe and PayPal.
What is an e-commerce CRM?
An e-commerce CRM is the back office of an online store: one record per buyer with orders, payments, shipments and questions. In CRMiUS an order from your site becomes an invoice on the buyer’s card, is paid through Stripe or PayPal, leaves the warehouse with a delivery note, and after-sale questions arrive as tickets on the same card.
- Connection to the shop: REST API and webhooks, plus web-to-lead forms for inquiries.
- Plans from $100 per month; 14 days free on every plan, full access, no bank card. Compare plans
- Interface in English, Ukrainian, Russian, German and French.

How an online order runs through CRMiUS
One order touches five parts of the system. Each step leaves a document on the buyer’s card, so anyone on the team can see where the order stands.
- 01OrderThe site passes the order to the REST API, and it is recorded as an invoice on the buyer’s card.
REST API · webhooks - 02PaymentThe buyer pays by card through Stripe or PayPal; the payment lands on the invoice.
Paid - 03ShipmentThe warehouse issues a delivery note, and the item leaves the stock of its warehouse.

Everything about a buyer on one screen
Open a customer and every document is one tab away: what they bought, paid, returned and asked.
- Contacts, billing and shipping addresses, customer group
- Invoices, payments and credit notes with a statement
- Support tickets, files, notes and reminders
- Customer portal: the buyer sees invoices and pays online
From paid invoice to parcel

Stock is kept per warehouse, so the team packs from the right shelf and the balance on the screen matches the shelf. When the warehouse issues a delivery note, the item leaves stock and the shipment appears in the buyer’s history.
- Several warehouses, each with its own balance, and transfers between them
- Goods receipts and delivery notes with a movement history per item
- Minimum and maximum stock per item with a reorder alert
- Serial numbers and expiry dates where the goods need them
- Inventory counts
