Billing // Systems TTY0 · 80×25 · PHOSPHOR P1

Invoicing,
uncapped.

Unlimited clients and invoices, multi-currency, PDFs and shareable links — for solo consultants and the small teams billing right alongside them.

No artificial limits. No feature paywalls. Just the invoice, the payment, and a quick look at where your money stands.

// The pitch

Software shouldn't ration your clients.

The tool I used before capped me at three clients, then asked for $300+/year to go further — paying a premium not for more value, but to undo a limit someone invented. Most of the time you just need to send an invoice and check what you're owed. So that's what this does, without the meter running.

// Module manifest

Everything you need to get paid.

Eight modules, all loaded — no tiers to unlock them.

MOD·01

Invoices

Build invoices with inline line items and live totals. Drop in discount lines, issue with sequential numbering under your own prefix, then duplicate, void, or track them through a clean draft → sent → paid lifecycle with due dates and overdue flags.

MOD·02

Multi-currency

Invoice in USD, EUR, or CAD. Totals stay grouped by currency and are never blended into one misleading number — each currency is tracked on its own.

MOD·03

Clients

Keep contacts, billing addresses, a default currency, and notes for each client. Archive the dormant ones, and open any client to see its own billing summary and recent invoices.

MOD·04

Payments

Record payments as they land — in full or partial. Balances and status update themselves, so an invoice moves to partially paid or paid on its own and you always know what's still owed.

MOD·05

PDF & public links

Every invoice renders to a clean PDF and a shareable link your client can open with no account and no login — just the invoice, viewable or downloadable.

Dashboard

See outstanding balances and what's been paid this month, grouped by currency, alongside unpaid and overdue invoices sorted by due date. Your finances, at a glance.

Email templates

Customizable invoice-sent and payment-received templates, with fill-in variables like invoice number, totals, and the public link — and you can override subject and body per client.

MOD·08

Passkey security

Passwordless sign-in with passkeys — nothing to remember, nothing to leak. Admins can run more than one company from a single account and switch between them.

// Operators

Built for one. Scales to a few.

Whether it's just you or a small crew, the limits stay off.

01 · Solo consultants

Send invoices, track what's paid, and check your finances without a subscription tier deciding how many people you're allowed to work with.

02 · Small teams

Invoicing multiple clients across currencies, without per-client caps or per-seat upsells getting in the way of just getting paid.

03 · Switchers

Moving off a capped tool? Set your starting invoice number so the sequence continues from your previous platform — no awkward reset to #1.
