Invoice app maker

An invoice app turns "I will send the bill later" into a finished invoice before you leave the customer. Describe your business and how you bill, the AI agent builds a real Android app, you create a test invoice in the emulator preview and download the APK. The idea above covers customers, items, tax, numbering and paid or unpaid tracking.

What your invoice app will have

From the idea above, the agent builds the screens a small business uses every day:

• Dashboard — unpaid total, overdue invoices, and what you invoiced this month.
• Invoices — every invoice with number, customer, date, total and a Paid or Unpaid tag, with filters.
• New invoice — pick a customer, add items and quantities, apply a discount and tax, and see the total update as you go.
• Invoice view — a clean printable page with your logo, business details, the next invoice number and payment instructions, ready to share.
• Customers — names, phone numbers, addresses and each customer's invoice history.
• Items — products and services with a default price, so regular jobs are one tap.
• Settings — business details, logo, tax ID, currency and the invoice number format.

Features you can ask for

• Quotes that turn into invoices with one tap once the customer agrees.
• Partial payments with the balance still due.
• A reminder on your phone when an invoice is a week overdue.
• Monthly and yearly sales reports, and your best customers.
• Stock that goes down when an item is invoiced.
• Receipts for cash sales in the same numbering.
• Your bank details or a payment link printed on every invoice.

Ideas to make it yours

Shops that bill at the counter should read the bill and invoice app guide for a small shop. If you also want stock, purchases and profit, the inventory and sales app guide shows how to grow the invoice app into one.

Get it on your phone

1. Press Build this invoice app and sign in with Google.
2. Enter your business details in the emulator preview, add two customers and three items, and create an invoice.
3. Ask for changes in plain words: "put the logo on the left", "show tax per item", "start numbering at INV-0100".
4. Press Download APK and install it on your Android phone.
5. For Google Play, build the signed APK and AAB from the same menu; the APK builder page explains signing and upload.

Recreate three invoices you have already sent, with the same items, discounts and tax. If the totals match exactly, you can trust the app with the next hundred.

Before you rely on it

An invoice is a business record, so take a few minutes to get the rules right. Decide your numbering once and never reuse a number; the app can lock numbers so a deleted invoice leaves a gap instead of a duplicate. Ask your accountant which details your invoices must show — tax ID, customer tax ID, tax breakdown, payment terms — and put that list in your request. Keep an online copy or a regular backup, because phone-only records disappear with the phone. Remember that the app records payments rather than collecting them: print your bank details or a payment link on the invoice and mark it paid when the money lands. For the wider picture, read an app for a small business without hiring a developer.
