Approval automation: expenses, time off, purchases and permissions that travel on their own

The problem

Every growing company runs into the same bottleneck: approvals. Team expenses, time-off requests, purchase orders, special customer discounts, permissions to release payments, authorizations to access sensitive information. What a 5-person company resolves over chat becomes a nightmare in a 40-person company.

The typical situation: someone sends an email asking for approval, the recipient is in a meeting, the requester asks again, the recipient forwards it to someone else because it's not their area, it gets lost in a chain of replies, and in the end nobody knows who approved what or when.

The traditional answers were complex BPM/workflow tools (Kissflow, Pipefy, Monday Forms) or approval modules of giant ERPs (SAP, Oracle). None work well for SMBs: they're either expensive, require consulting to set up, or don't integrate WhatsApp as a mobile approval channel.

How Pilot solves it

Approval automation — done right — combines (a) a configurable flow per request type, (b) notifications to the approver wherever they are (WhatsApp, email, app) and (c) a complete audit log of who approved what and when.

Three principles to get it right

1. Define flows, not email chains. Each request type (expense, time off, purchase, discount) has its own flow: who approves, what amount requires what level, what happens if no one responds in X hours.
2. Where the approver is, not where it's convenient for you. If the manager is on a job site all day, they get the approval over WhatsApp and decide it with one tap. Without opening a computer.
3. Always an audit log. Who requested, who approved, at what moment, with what attachments. This becomes critical for compliance, internal review and external audit.

Step by step

1. Identify the 5-10 most frequent approval flows in your company: team expenses, time off, purchase orders to suppliers, special discounts, access to sensitive information, payment release, hiring, advances.
2. For each flow, define the levels by amount/criticality. E.g.: expenses up to US$200 = direct supervisor; up to US$1,000 = area manager; over US$1,000 = general management + CFO.
3. Define automatic escalators: if the approver doesn't respond in X hours, it escalates to their backup. If no one responds in Y hours, it sends an alert to the director.
4. Connect the flows to existing systems: expenses to the accounting/billing system; time off to the HR module; purchases to the ERP/Odoo; discounts to the CRM.
5. Turn on multichannel notifications: the approver gets the request over WhatsApp (with Approve/Reject/Request info buttons), by email (with a link to the detail) or in the mobile app. They pick the channel they prefer.
6. Set up auto-approvals for trivial cases: expenses under US$50 with valid justification, time off requested more than 30 days in advance with no conflict, recurring office purchases with a usual supplier.
7. Implement an immutable audit log: every request is recorded with timestamp, requester, approver, attachments, comments. Exportable for external audit.
8. Measure: average approval time (before vs after), % of approvals that escalated, expenses approved by category, bottlenecks by approver.
