Billquay Ledger

Import the invoice list from your accounting or billing system. Billquay shows open AR, what is overdue and by how many days, aging across current to 90+, who owes the most, and a worst-first issue list so collections stay on track.

What it does

Every invoice in one register

Customer, issue and due dates, amount, status and collector. Re-import any time and invoices update by id.

Open vs paid

See open AR, paid totals and voided invoices without opening the accounting system.

Aging buckets

Current, 1–30, 31–60, 61–90 and 90+ day buckets with amounts, so overdue cash is visible at a glance.

By customer

Open AR and overdue amounts by customer, with concentration flagged when one account is 40% or more of open AR.

120-day calendar

Upcoming due dates on one dated list, with the worst overdue items ranked first.

Tamper-evident and private

Every import and note is SHA-256 hash-chained and stays in your browser. Export a report, a register CSV or the journal itself.

Billquay Ledger

Your data stays on this device (browser storage). Nothing is uploaded. Billquay reads the invoice register you provide. It is not a substitute for accounting software.
