The month turns and the list is ready

Three screens from the running app, in the order the month happens.

  1. 1 of 3

    The month turned

    November 1st: all 12 payments are already under Due, same amount, same day.

    The This month screen on November 1st, Due group: 12 payments adding up to R$3,010, each with its due day. Demo data; the app is in Portuguese.

    All 12 November payments, R$3,010 in total, showed up without anyone typing them.

    The square is the due day. Today's is filled in.

    You can remind people before the day: the message turns into a reminder.

  2. 2 of 3

    Who paid, who's due, who's late

    Each group with its total. Late payments come first, in red.

    The This month screen in October: R$1,880 in out of R$3,010, a bar split into paid, due and late, and five late payments. Demo data; the app is in Portuguese.

    How much has come in this month, out of how much.

    Late payments sit at the top, with their total.

  3. 3 of 3

    Remind in one tap

    Name, amount, due date and the Pix code are already in the message.

    The reminder sheet for Bruno: a ready message with R$220.00, due 10/10, the Pix code with the amount, and the Open in WhatsApp button. Demo data; the app is in Portuguese.

    The message is ready, with the right name and date.

    The Pix code already carries the amount. The money lands in your account.

    Opens your client's WhatsApp chat with the text in the box. You check it and send.

Screenshots of the running app at phone width, with demo data. The interface is in Brazilian Portuguese.

A tuition tracking app that copies the month for you

In a spreadsheet, each client means 12 entries a year; in Diafixo, just one.

220 fewer entries a year

20 clients × 12 months = 240 spreadsheet entries. In Diafixo, 20: you add each one once. Sample math, using your number.

Made for people whose clients pay every month

  • Your client's Pix lands straight in your account, with no platform fee on top.
  • New phone? Sign in with the same email and your list is there.

Questions

Do I have to enter everyone every month?

No. You add each client once: name, WhatsApp number, amount and due day. On the 1st, that month's payment shows up by itself. Paused clients are skipped.

Does the app charge my clients automatically?

No. You tap Charge, WhatsApp opens with the message and the Pix code ready, and you send it. When the Pix lands, you tap Paid.

Is there a client limit?

Yes: 150 on Solo, 400 on Equipe and 1,000 on Empresa. At the limit, only adding a new client asks you to upgrade, and nothing you already have disappears.

Who is it for?

Anyone in Brazil who gets paid monthly by Pix. The app, the reminder messages and the billing are in Brazilian Portuguese and reais.

Add them once and let the month turn.
