Billwise: Invoice & Estimates

Billwise is an offline invoice and estimate maker for people who bill their own clients - freelancers, contractors, and small businesses who need a document out the door in minutes, not an accounting suite.

Pick a client, add what you're billing for, and Billwise handles the math: line totals, discount, tax, and grand total. Generate a clean PDF and share it or print it straight from your phone.

INVOICES AND ESTIMATES, ONE FLOW
Send an estimate first. When the client agrees, turn it into an invoice with a single tap, numbered automatically with your own prefix and sequence.

DUPLICATE IN TWO TAPS
Billing the same client again for similar work? Duplicate any invoice or estimate and only change what's different, instead of rebuilding a document from scratch every time.

KNOW WHAT YOU'RE OWED
Set a due date and Billwise flags overdue invoices automatically, with your total outstanding balance right at the top of the list - no more scrolling through every document to figure out who still owes you money.

MONTHLY REPORTS
See six months of invoiced and collected amounts at a glance, plus the clients with the largest outstanding balance, so you know exactly where to follow up first.

CLIENTS AND ITEMS YOU REUSE
Save a client once and pick them from a list next time. Save your usual services or products with prices so you're not retyping them on every document.

TAX, DISCOUNTS, MULTIPLE CURRENCIES
Set a tax rate and discount per document, and choose from a wide range of currencies, including zero-decimal currencies where amounts aren't split into cents.

PDF, SHARE, PRINT
Every invoice and estimate renders as a formatted PDF you can share by email, messaging apps, or AirDrop, or send directly to a printer.

FULLY OFFLINE, NO ACCOUNT
Billwise works with no internet connection and no sign-up. Your client list, items, and documents stay on your device.

FREQUENTLY ASKED QUESTIONS

Can I track partial payments on an invoice?
Yes. Record one or more payments against any invoice and Billwise calculates the remaining balance automatically - the invoice shows as partially paid until the full amount is recorded.

Does Billwise report anything to tax authorities?
No. Billwise is a document and record-keeping tool for your own use - it doesn't file, transmit, or report anything to any government or tax authority on your behalf.

What happens to my documents if I switch phones?
You can export a full backup file and restore it on a new device. Either way, your data stays under your control, not on our servers.

What's included in the starting plan versus Premium?
The starting plan includes 3 documents a month with a small watermark on the PDF, with every core feature - clients, items, tax, discounts, PDF - fully working. Premium is a one-time purchase that removes the limit and watermark.

What does Premium unlock?
A one-time purchase of $29.99 unlocks unlimited documents, removes the watermark, lets you add your own logo, and adds CSV export. No subscription, ever.

BILLWISE PREMIUM
One purchase, forever: unlimited invoices and estimates, no watermark, your own logo on every PDF, and CSV export for your records. Available in 8 languages.
