From bill to payment,
automated.
Create bills, manage vendors, track payments, monitor aging. Zera handles your entire AP workflow with AI-drafted journal entries and one-click approvals.
The full workflow
From bill receipt to full payment.
Every bill moves through four stages. Zera drafts the entries, routes approvals, tracks aging, and closes the loop on payment.
Create or receive bill
Upload a PDF, enter manually, or capture via email. AI drafts line items from the invoice.
Approve
Single-step or multi-step approval workflow. Route to the right reviewer. Full audit trail.
Track aging
Current, 1 to 30, 31 to 60, 61 to 90, over 90 buckets update automatically as bills age.
Pay and record
Record full or partial payment, auto-generate the journal entry, close the bill.
Bill management
Draft. Approve. Pay.
Every bill progresses through Zera's workflow: Draft to Pending Approval to Approved to Partially Paid to Paid. AI drafts bill entries from uploaded invoice PDFs. Line items preserved. Status always current.
- Upload PDF or create manually
- AI-drafted from invoice extraction
- Multi-step approval workflow

Vendor management
Every vendor. One record.
Vendors in Zera hold billing info, payment terms, default GL accounts, and tax IDs. Vendor records connect to bills, POs, and payments. W-9 tracking, 1099 flags, and payment preferences all in one place.

Purchase orders
