Nightingale · Operational Control
Approval workflow automation for operational businesses.
Purchasing, compliance and management approvals — routed to the right authority, checked against budget, and evidenced end to end. Control what gets committed before it costs you.
What Zevolo controls
Purchasing approvals
Every spend request routed, capped and matched to budget before money moves.
Compliance approvals
Policy sign-off captured with evidence, timestamps and named accountability.
Management workflows
Delegated authority, escalation and cover — enforced, not remembered.
Requests
One intake for purchases, changes and exceptions. Nothing runs off-system.
How approvals run
Request → Route → Control → Evidence
Step 1
Request
Staff raise purchases, expenses and change requests in one controlled intake.
Step 2
Route
Value thresholds and delegated authority decide the approver. No inbox chasing.
Step 3
Control
Commitments checked against live budget before spend is authorised.
Step 4
Evidence
Immutable audit trail ready for finance, auditors and the board.
Operational control
Approvals are where operational control is won or lost.
Control committed spend
Purchase and expense requests are checked against budget and authority limits before approval.
Stay audit-ready
Compliance sign-off is captured with evidence and timestamps — no reconstructing the paper trail.
Keep operations moving
Escalation, delegation and cover stop requests stalling with one absent approver.

Pricing questions
How much does Zevolo Pro cost?
Pro is £9.99 per user per month. Annual billing is £99.90 per user per year, which is two months free.
Is Zevolo priced per user?
Yes. You pay for the people in your workspace, and you can add or remove users at any time — your bill follows the user count.
Is there a free plan?
Yes. Starter is free forever and includes up to 5 users, 3 workflows and one organisation.
What is the Nightingale bundle discount?
If you subscribe to 3 or more Nightingale applications, 20% comes off your qualifying recurring subscription charges, including Zevolo.
How do annual pricing and the bundle discount combine?
Annual pricing is applied first, then the 20% bundle discount is taken off the annual amount. Ten users on annual billing with 3 apps is £999.00 less £199.80, so £799.20 a year.
What does Enterprise cost?
Enterprise is custom priced, based on team size, governance scope and integration needs. Talk to sales for a quote.
