WHY SUBMO

✓ Works without internet

All data is stored on your phone. You can create invoices in the field, at the project site, or anywhere without a signal.

✓ Directly to WhatsApp

Once created, the PDF is immediately shared with the customer's WhatsApp, complete with a pre-filled draft billing message.

✓ Adapted to Indonesian needs

• Automatically printed in Indonesian


• VAT column with your own percentage set


• Place for NPWP and account number in the document header


• Your QRIS appears on every document


• Correct rupiah format: Rp1,250,000

✓ Signature & Stamp

Set your signature and business stamp once in the settings — both are printed on every document, complete with your name, title, city, and date. Paid receipts are stamped "PAID."

✓ Due Date Reminder

Your phone will remind you the day before, the day it's due, and again after it's past due — so you don't forget to collect any bills. You set the time, and you can turn it off at any time.

✓ Recurring Invoices

Subscription clients billed monthly only need to be set once. The next period's draft invoice will be waiting when you open the app.

✓ Client & Item Data Saved

You don't need to retype the same customers. Simply select the list of goods and services and their prices. You can copy last month's invoice into a new one in three taps.

✓ All features unlocked from the start

No locked features, no monthly subscriptions, and no per-document fees. Every document you create carries a small line www.submo.id at the bottom of the page.

SUITABLE FOR

Freelancers • Designers • Photographers • Contractors • Service Providers • Caterers • Printers • Consultants • Online Stores • Agencies • Any service provider who needs to invoice neatly.

PRIVACY

Submo doesn't require an account. Your invoices, customer data, and sales figures are only on your phone — you can back them up anytime to a single file. Due date reminders are scheduled by your phone itself, not sent from any server. No data is uploaded anywhere.
