Control by Harpia Lab

Stop chasing clients over WhatsApp.

With Control, your quote becomes a link. Your client accepts it on their phone, the installments are agreed up front, and you see what has come in and what is still due, no spreadsheet needed.

The Free plan has no time limit. Pro comes with a 30-day trial, no card required.

In Control, the quote Café Aurora brand identity is in review. The client, Marina, opens the link on her phone and taps Accept quote. The status changes to Accepted and three installments of R$ 1,600.00 appear.

From quote to paid, in four steps

The same path you already follow, without losing anything along the way.

  1. 1.Quote

    Attach the PDF, set an expiry date and send the link wherever your client already talks to you.

  2. 2.Approval

    Your client opens it on their phone and accepts with one tap. You hear about it right away.

  3. 3.Installments

    Split it into a down payment and installments. Your client sees every due date and, on Pro, gets a reminder before it.

  4. 4.Paid

    Record each payment and see what came in, what is left and what is late.

Everything that comes after “send me a quote”

Built for people who work solo or with a small team and don't want to become debt collectors.

Online acceptance and client portal

Your client opens the link, reads the quote and answers right there. Nothing to install.

Financial dashboard

Receivable, received and overdue in one place, with month-by-month history.

Optional items

Offer extras in the same quote. Your client ticks what they want and the total adjusts.

Automatic reminders and follow-upsPro

The installment reminder goes out on its own before the due date, and a quote with no answer gets a follow-up. You don't have to send a message.

Quote versions and attachmentsPro

Scope changed? Send the new version. The history stays on record.

Installments and Pix copy-paste

The Pix code goes with each installment, ready for your client to pay.
