Upload a PDF to Create Your Next Invoice

Turn last month's invoice into this month's in one click

Every PDF you download embeds your invoice data. Upload it next month and the tool auto-increments the invoice number, advances all dates by one month, and pre-fills every field. No re-typing, no copy-paste.

The Recurring Invoice Problem

If you send the same client an invoice every month, you know the drill: open the tool, re-enter sender and recipient details, copy line items, update the invoice number, fix the dates. It takes five minutes of tedious work that adds up fast.

The upload PDF feature solves this. Every invoice you download from this tool contains embedded metadata. Upload that PDF later and the tool reconstructs the entire invoice, then automatically prepares the next one.

How It Works

Click the "Upload PDF" button at the top of the form.

Select any PDF previously downloaded from this invoice generator. The tool reads the embedded invoice data and loads it into the form instantly.

No server, no account, no cloud storage. The data lives inside the PDF file itself.

What Gets Auto-Filled

When you upload a previous invoice PDF, the tool restores everything and then prepares the next invoice:

  • Invoice number is auto-incremented (001 → 002, INV-2026-01 → INV-2026-02)
  • All dates advance by one month (invoice date, due date, quote validity)
  • Sender & recipient details are fully restored (name, address, VAT ID, contact info)
  • Line items carry over with descriptions, quantities, and rates intact
  • Time report periods advance one month with entries cleared for new data
  • Settings are preserved (VAT mode, rounding, currency, discounts)
  • Payment methods and notes carry forward
  • PDF preferences are restored (template, color palette, paper size, language)

Smart Invoice Number Incrementing

The tool intelligently parses your invoice number format and preserves your numbering convention:

  • Simple numbers: 001 → 002 (padding preserved)
  • Prefixed numbers: INV-001 → INV-002
  • Date-based numbers: 2026-01-001 → 2026-01-002
  • Complex formats: ACME/2026/017 → ACME/2026/018

Whatever numbering scheme you use, the tool detects the numeric suffix and increments it while keeping the prefix and zero-padding intact.

A Typical Monthly Workflow

Here is what a recurring invoicing workflow looks like with this feature:

  1. Month 1: Fill in the form manually and download the PDF
  2. Month 2: Upload last month's PDF. The form is pre-filled with invoice #002, dates moved forward, all details intact. Update line items or time report entries, download the new PDF
  3. Month 3 and beyond: Upload last month's PDF, adjust, download. Each PDF becomes the seed for the next

The result: recurring invoicing drops from a 5-minute chore to a 30-second task. No templates to manage, no accounts to maintain.

Privacy & Data Handling

The upload feature works entirely in your browser. The PDF is never sent to a server.

  • Invoice data is embedded in the PDF metadata when you download it
  • On upload, the browser reads the file locally using standard web APIs
  • No network requests are made during the process
  • Your invoice data stays on your device at all times

This is the same privacy-first approach as the rest of the tool: no accounts, no tracking, no server-side storage.
