What CustomInvoice does

The whole feature set, as it exists in the build being submitted. Nothing on this page is planned, in beta, or coming soon — the things that are not built yet are listed at the bottom instead.

Documents issued by your own business

Invoices for work you have done, estimates or quotes before you start, and sale receipts you hand over on the spot
Every document carries your business name and address as the issuer, and goes to your own client
Line items with quantities and rates, with the total updating as you type
Your own numbering: set the prefix and the starting number, with a separate sequence for each document type
A number is never reused once issued, even if you void the document that used it
Save a client once and reuse them, or add one without leaving the invoice you are writing

PDFs your client will take seriously

Three templates: Classic, Modern and Minimal
Your logo and your brand colour on every page, from a palette picked for legibility, or a colour of your own
No watermark on any page, on any template
Send by email straight from the app, or push it through the share sheet
The PDF travels through your own mail app or share target, never through us
A document is marked as sent only when you say it went out

Getting paid, and seeing who has not paid

Record as many part payments as you need against one invoice, and watch the balance fall
Paid, part paid, outstanding and overdue are computed from the payment record every time they are shown, never stored
The documents list shows what is still owed on a part-paid invoice and how late an overdue one is
Balance due is the figure that stands out, on screen and on the printed document
Mark as sent, void and delete are reachable from a button on each row
Voiding keeps the document and its number in your records instead of erasing the history

Tax and discounts that add up

Named tax rates that you create, applied per line, so taxable labour and exempt materials bill correctly on one job
Discount a single line, or the whole document
Every amount is a whole number of cents and every quantity a whole number of thousandths
Line totals are rounded individually and then summed, so the total equals the column your client is reading down

Reports, and something to hand your accountant

What you are owed, and how much of it is late
Aging buckets, so you can see how late
Billed and collected by month
CSV export of your documents and your payments

Private by design

No account, no login, no cloud sync
Your clients, your rates and your documents are written to your device and never uploaded
Writing a document, rendering the PDF and recording a payment all work with the radio off
No bank connection and no card processing, in this version or any future one
Anonymous, bucketed usage counts that never carry an amount, a client name, or any document content
Light or dark, and the app remembers which you chose

What it does not do

Worth knowing before you download, rather than after.

No import of any kind. There is no spreadsheet import, no file import and no migration from another app. Data travels out as CSV, not in.
No thermal or 80mm receipt template. There are three templates, not four.
No reminders. The app will not chase an overdue invoice for you, and sends no notifications at all.
No backup-and-restore file. CSV is a report for your accountant, not a restorable backup, so the phone is the only copy of your live records.
No printing from the preview, and no second share button there. Sending has exactly one path, which is what makes "sent" mean something.
No recurring or repeating invoices.
No iPad layout. The app installs on an iPad in compatibility mode, as an iPhone-shaped window.
No Android release, and no Google Play listing.
No multi-business support, no per-document currency, no time tracking, no expenses and no purchase orders.
No payment processing. You can put a "pay me here" line in your payment instructions, but the app does not take money.
No tax filing and no jurisdiction lookup. It records the rates you enter and reports what you collected.
