Built for the teams who carry the balance.

01

Accounting firms

The firm is responsible for the chase, and the client still owns the books. Zen keeps those two facts apart.

• A tenant per client, or a separate deployment when the engagement needs a harder boundary than a shared application.
• Staff see only the clients and the actions their role allows. An auditor can read the trail without being able to send a link.
• The firm’s collection record and the client’s accounting file are checked against each other, and the differences are listed.

02

Growing businesses

The invoice is already a PDF in someone’s sent folder. The missing piece is a record of what happened after it was sent.

• Upload the invoices you already produce. Zen checks the lines and opens the payment cycle.
• One dashboard for collected, outstanding, overdue, and due in the next seven days.
• Payment links by email, SMS, or WhatsApp, without standing up a second collections tool.

03

Subscriptions and retainers

Recurring revenue fails in the quiet weeks, when nobody remembers to raise the invoice or to ask again.

• A pay cycle holds the customer, the amount, the currency, the day, and the branding.
• Each period, Zen issues the invoice, logs it on the system of record, and sends the collection.
• A failed payment or a short payment stays on that cycle, and the next notice knows about it.

04

Enterprises

Large finance teams do not need another general ledger. They need the collection work, the control, and the evidence.

• SAP or NetSuite remains the system of financial record. Zen syncs customers, invoices, and payments, and reports the variance.
• Maker-checker sits on releases, write-offs, and changes to vendor or customer bank details.
• Auditors receive purchase orders, receipts, statements, and the collection history as one pack.

05

Professional services

Retainers, milestones, and expenses land on the same client, and the argument is usually about a line, not the relationship.

• Line-item checks compare the invoice with the engagement: the purchase order, the milestone, the agreed rate.
• Several invoices for one client can share a payment link, with each invoice still tracked on its own.
• A disputed line pauses collection. A write-off needs a second person.

06

Groups and multi-entity companies

A group wants a view of cash. It does not want one shared book that an auditor cannot untangle.

• Each entity is its own tenant, with its own roles, cycles, and audit trail.
• A group view is a report across tenants, not a permission to edit another entity’s invoices.
• Dedicated deployments remain available where a subsidiary, or a client of a firm, must be physically separate.
