One link for every platform

One link to accept Bank, Crypto, and Card payments.

Get a secure profile like paycilo.com/@yourname that displays all the ways to pay you. Paste it in your social bio, print it as a QR card, or embed it on your website.

Stop guessing why they didn't pay.

Gain X-ray vision into your checkout. Our Friction Radar detects rage clicks, method switching, and latency issues in real-time. Use proprietary fingerprinting to identify drop-offs and recover revenue.

Remove the friction from
direct payments.

One profile for everything

Stop asking "Do you have Zelle?". Link your Bank, Crypto, and Payment Apps in one place.

Zero typing errors

Clients copy your exact details with one tap. No more manual entry mistakes or lost funds.

Encrypted Account Details

Your banking info is encrypted and hidden behind a secure button. It is only revealed when your customer is ready to pay.

Get paid for your work,
not your patience.

Send clients a clean payment link instead of an awkward text. Accept project fees, tips, or support in Bank Transfer or Crypto.

  • Attach your Paycilo link to PDF invoices and emails
  • Accept Crypto (USDT/BTC) from international clients easily
  • Digital Tip Jar for blogs, streams, and tutorials
  • Keep your personal banking details private
  • Settles instantly—no "3-day withdrawal" holding periods

Turn your DM's into
a professional checkout.

Stop sending manual account numbers to every customer. Close sales faster on WhatsApp and Instagram with a verified business link.

  • One bio link for Instagram, TikTok, and Facebook
  • Safe for delivery riders—confirm payment before handover
  • Look like a registered company, not a personal account
  • Instant payment history for effortless bookkeeping
  • Eliminate "fake transfer" screenshots with real-time verification

The "Cash-Only" speed
without the cash.

Replace expensive POS terminals with a simple Countertop QR Card. Customers scan, pay via their app, and you get a notification instantly.

  • Print your custom QR Card immediately—no hardware to buy
  • Ideal for busy market stalls, food trucks, and pop-ups
  • Keep the queue moving during rush hour
  • Zero transaction fees—keep 100% of your sale price
  • Works even when the POS network is down
Slider Image

Modernise your offering
without losing the spirit.

Congregations carry phones, not cash. Give them a respectful, seamless way to tithe or donate instantly during service or from home.

  • Accept tithes, offerings, and building funds in one tap
  • Project a scan-to-give QR code on the main screen
  • Perfect for youth events, retreats, and fundraisers
  • Transparent, tracked records for church accounting
  • No card terminals needed—just their own bank app

One Paycilo for every
chat, bio and reply

Drop your Paycilo on WhatsApp, Instagram and anywhere people ask for your account details. They choose their bank, enter an amount and pay. You get clean records without sharing account numbers ten times.
