Every client and product — saved once, ready everywhere

Stop retyping the same address and the same price on every invoice. Save a client, save a product or service, and Invoice OS autocompletes both from your very next invoice — while every one you've already sent stays locked in exactly as it was billed.

Two records, one invoice

How it fits together

Clients and products are saved independently, but both feed the same autocomplete — and the same permanent snapshot — the moment you create an invoice.

One finalized invoice = a permanent snapshot

Editing a client's address or a product's price later never rewrites an invoice you've already sent — each one keeps its own locked-in copy, forever.

Clients

Your business contact book, built for billing

Not a generic address book — every client record is connected to the invoices they've actually received.

Name, company,

email, phone & address

Autocomplete on every invoice

Start typing a name — the right client is one click away, every time.

Search & filter

Outstanding Balance and Overdue-Risk views surface exactly who to follow up with first.

Receivables at a glance

Total Billed, Outstanding Receivables, and average payment cycle — computed from real invoice history, not estimated.

Full history, one page

Every client has their own page listing every invoice ever sent to them.

Archive without losing history

Remove a client from your active list — their past invoices stay exactly as they were.

List or grid view

Switch between a compact list and a visual card grid, whichever fits your day.

Products & services

Your catalog, ready to bill in one keystroke

Whether you sell physical goods, hourly services, or fixed packages — set it up once, invoice it in seconds from then on.

Name, category,

SKU & price

Autocomplete on every invoice

Type a product or service name — the price and category come with it.

Organize by category & SKU

Keep goods and services tidy, however many you sell.

Price once, reuse everywhere

Set a price on the record — still editable per invoice for one-off discounts or adjustments.

Retire without deleting

Mark a product inactive to pull it out of autocomplete instantly — nothing about past invoices changes.

Live catalog stats

Total, active, inactive, and average active price — always current.

List or grid view

The same compact-list/visual-grid toggle as clients, for a catalog of any size.

Stop retyping the same client and price, invoice after invoice

Save each client and product once — Invoice OS autocompletes them from your very next invoice, and every one you've already sent stays exactly as billed.
