OPSKAP OS
Client management

Every client, with their money and paperwork attached

A client card shows their invoices, documents, VAT details and notes — not a heavyweight CRM, just what you actually need.

OPSKAP OS keeps client management honest: a client is a company or an individual, with registration and VAT numbers, contacts and address. Every invoice you issue and every contract you store is linked to them, so the full picture is one click away.

For agencies billing across brands, clients are scoped per company — Client A of your studio never mixes with Client B of your consultancy, yet you see both from one dashboard.

🏢

Companies & individuals

B2B and B2C clients with the right fields for each — VAT numbers for firms, simple contacts for people.

Linked invoices

Open a client and see everything you ever billed them — paid, outstanding, overdue.

Contracts, NDAs and IDs attached to the client they belong to.

🗒

Common questions

Is this a CRM?

A lightweight one: clients, their money and their paperwork. No pipelines, no lead scoring, no configuration hell.

Can one client belong to two of my companies?

Clients are scoped per company to keep the books clean — add them to each entity that bills them.

Can I import clients?

You can add clients in seconds manually; CSV import is on the roadmap.
