It knows the dates.
1st to 15th, 16th to end of month, every week, or every month. Singil suggests the next period and never makes you type a date. Arrows move it if you need to.
Your next invoice,
in two taps.
Singil is for freelancers who bill the same clients every payday. Save a client once with their rate and schedule. After that, tap their name and tap Create & Share. The period, the rate, the invoice number and last time's hours are already filled in.

Create & Share
1
Save the client once.
Name, rate, what the work is, the currency, and how often you bill them: weekly, twice a month, or monthly.
2
Tap them on payday.
The next billing period is already picked, and last invoice's hours are already in. Change the one number that changed, if anything did.
3
Create & Share.
A clean PDF goes straight to the share sheet: Mail, Messages, Messenger, WhatsApp, Viber, Files.
A returning invoice takes two taps when nothing changed, three when the hours did.
Not accounting software.
Just the invoice.
A PDF you'd send.
Clean type, your logo if you have one, your payment details at the bottom. A4, or US Letter for USD and CAD clients. The file is named for the client, not a string of numbers.
Old invoices stay put.
Each invoice keeps its own copy of who, what and how much. Change a client's rate next month and last month's invoice still says what you sent.
Nothing leaves the phone.
No account, no sign-in, no server, no analytics. Your clients and invoices live on your device. Nothing is uploaded unless you share the PDF yourself.
One price. Paid once.
