Novus PDF Studio
Fill and sign invoices and receipts
Finish an invoice or receipt in Novus PDF Studio: upload the document, place number and date-style fields for amounts and dates, add text fields for line items and notes, draw a signature where the record needs one, and export a clean copy while the original stays untouched.
Invoices and receipts are forms with a particular shape: a column of amounts, a subtotal, tax, and a total, a couple of dates that have to be right, a few lines of description, and often a signature that approves the charge or acknowledges the payment. Novus PDF Studio, the free browser editor at pdf.novusstreamsolutions.com, is built to finish exactly this kind of document. You upload the invoice or receipt, drop number and date-style fields where the figures and dates belong, add text fields for the line items and notes, sign it if the record needs a signature, and export a clean copy. This guide stays on the money side of the job — amounts, dates, totals, and signing — rather than the generic first-form walkthrough, which the getting-started tutorial already covers.
It helps to be clear about one boundary up front, because it shapes how you work. PDF Studio places a number field for you to type an amount into; it does not add those amounts up. There is no formula, no auto-sum, no running total — the editor is a fill-and-sign workspace, not a spreadsheet. That means you still calculate the subtotal, tax, and total yourself and type the result, and the single most important review before you export is confirming the arithmetic agrees. The app also does not convert or compress files, run OCR on a scanned paper receipt, scrub metadata, or redact figures, and the signature you draw is a visual mark rather than a certificate-based digital signature. Knowing those limits keeps you leaning on the tool for the job it does well.

Two ways to finish
Scan, then check the figures
Run the AI scan to place likely amount, date, and line fields quickly, then verify every number and total by hand before export.
Build the template by hand
Place the number, date, and total fields yourself when you reuse the same invoice or receipt layout every month and want it exact.

1. Open the editor and upload the invoice or receipt
Start at pdf.novusstreamsolutions.com/editor and upload the document you need to finish. The invoice or receipt stays visible in the canvas the whole time you work, so you are always placing fields against the real printed layout rather than a guess. Whether it is a blank invoice template exported from your accounting software or a receipt someone sent you to complete and return, the editor treats it the same way: a fixed background you drop editable fields on top of.
Keep the original file untouched and work toward an exported copy. This matters more for financial records than for most forms, because you will often want the blank template again next month for the next invoice. Treat the upload as a starting point you never overwrite, and let the download at the end be the finished, one-off version for this particular charge or payment.
- Open /editor and upload the invoice or receipt PDF.
- The document stays visible while you place every field.
- Keep the blank template as-is; export a finished copy instead.

2. Let the scan suggest the amount, date, and line fields
If the document has the usual invoice structure — a stack of amount rows, an invoice date and due date, a totals block, a signature line — run the AI field scan first. It looks at the page and suggests likely fields as editable layers: number boxes over the figures, date-style targets on the date lines, text lines for descriptions, and a signature target where it spots one. On a tidy invoice the scan can place most of the skeleton for you in one pass.
Treat the result as a first draft, never a finished form. Walk each suggested field and confirm it landed on the right cell, because a number box that drifts one row up will put the wrong figure against the wrong label. If the scan is noisy on a dense receipt and crowds the totals block, clear only the AI fields and build that area by hand — both scanned and manual fields stay fully editable, so you can keep the good suggestions and rebuild the rest.
- The scan works well on repeated amount rows and date lines.
- Confirm each suggested field sits on the correct cell before filling it.
- Clear only the AI fields if the scan crowds the totals block.

3. Place number and date-style fields for amounts and dates
The number field is the right home for every figure on the document: unit prices, quantities, the subtotal, the tax line, and the final total. Add one over each amount and size it to sit inside the column so the digits do not spill into the description beside them. Remember what this field actually is — a field styled for numeric entry, not a calculator. It holds exactly the number you type and does nothing more, so you work out the subtotal, add the tax, and enter the total yourself. The editor will not flag a total that does not match its parts, which is precisely why the review step later matters.
Use date-style fields for the dates an invoice or receipt carries — the issue date, the payment due date, or the date a receipt was settled. Give these fields a little horizontal room, because a fully written date is longer than people expect and a box sized for a short numeric date will clip the moment you type a longer format. Once one amount field and one date field look right, they become the template for the rest: duplicate them to keep the sizing and styling consistent down the column rather than drawing each one from scratch.
- Number fields for unit prices, quantities, subtotal, tax, and total.
- Date-style fields for the issue date, due date, and payment date.
- The app does not total anything — type the figure you worked out.

4. Add text fields for line items, descriptions, and notes
The words on an invoice or receipt live in text fields: line-item descriptions, a purchase-order or reference number, payment terms, a billing address, or a short thank-you note at the bottom of a receipt. Place a text field for each one and drag it into the space the form leaves for it. Where a document repeats a description column down several rows, duplicate a text field to keep every line the same height and start position.
Style the text with the export-safe built-in fonts, which are the only fonts the editor uses: Helvetica, Times Roman, and Courier. These render predictably in every PDF reader, so the finished record looks the same to your recipient as it does to you. Courier is monospaced, which can be genuinely useful on a receipt where you want a column of figures or reference codes to line up cleanly. Whichever you choose, keep the font, size, and colour consistent across the document so the completed record reads as deliberate rather than assembled field by field.
- Text fields for descriptions, reference numbers, terms, and notes.
- Use only the export-safe fonts: Helvetica, Times Roman, or Courier.
- Keep one font and size across the record for a clean, consistent look.

5. Draw a signature where the record needs one
Plenty of invoices and receipts carry a signature line — an authorised-by signature that approves the charge, or a received-by mark that acknowledges a payment or delivery. Where the document has one, add a signature field over the printed line, open the signature tool, and draw your mark with a mouse, finger, or stylus. Redraw freely until it reads cleanly, then position the field so the signature sits just above the printed rule rather than on top of it or floating well above it. If the form asks for two signatures, an approver and a recipient say, add a separate signature field for each so both export at the right place.
Be clear about what this signature is. It is a practical visual mark placed on the page, which is exactly what approving an invoice or acknowledging a receipt normally calls for. It is not a certificate-based or cryptographic digital signature, and the editor does not claim to provide verified e-signature compliance. For everyday billing and payment records that is the right tool; if a particular workflow legally requires a verified digital certificate, that belongs to a dedicated e-signature service instead.
- Add a signature field over the authorised-by or received-by line.
- Draw with a mouse, finger, or stylus and redraw until it reads cleanly.
- This is a visual mark, not a certificate-based digital signature.

6. Review the totals, then export a finished copy
Before you export, read the document the way the person paying it will. The most important check on an invoice or receipt is the arithmetic, because the editor did not do it for you: confirm the line amounts add up to the subtotal, that the tax is right, and that the subtotal plus tax equals the total you typed. Then sweep the rest — no amount or date field left blank, dates formatted consistently, descriptions sitting in their cells, and the signature clearing its line. A wrong total on a sent invoice is far more costly to fix than the thirty seconds this pass takes.
When the figures agree and the layout looks right, export the finished PDF. Download it to email, upload, or archive the record, or print it when a paper copy is the deliverable. What you see in the editor is what comes out, so open the downloaded file once in a normal PDF reader and confirm every amount, date, and the signature survived the export exactly as you placed them. Keep the original template untouched so next month starts clean, and remember the export is a fill-and-sign copy, not a redaction or metadata-cleanup step — if a receipt carries sensitive detail that must be removed rather than merely covered, that is a job for a different tool.
- Re-check the math yourself; the totals are typed, not calculated.
- Confirm every amount and date field is filled and aligned.
- Open the exported PDF in a plain reader before you send it.
Check the arithmetic yourself before you export
The editor places number fields for you to type into, but it never adds them up, so the one review that matters most on an invoice or receipt is confirming that the subtotal, tax, and total actually agree with the line amounts. Do that, then open the exported PDF in a plain reader to make sure every figure and date rendered exactly as you typed it. Keep the blank template untouched and export a fresh copy for each new charge or payment.
Frequently asked questions
Quick answers to common questions about this topic.
How do I fill in an invoice or receipt PDF for free?
Open Novus PDF Studio at pdf.novusstreamsolutions.com/editor, upload the document, place number fields for the amounts and total, date-style fields for the dates, and text fields for the line items and notes. Draw a signature if the record needs one, then download or print the finished copy — no paywall stands in the way.
Does PDF Studio calculate the totals for me?
No. The number field is styled for numeric entry, not a formula, so it holds only the figure you type. Work out the subtotal, tax, and total yourself, enter the result, and double-check that the parts add up to the total before you export, because the editor will not catch a mismatch for you.
Which font should I use for the amounts?
Use one of the export-safe built-in fonts: Helvetica, Times Roman, or Courier. Courier is monospaced, so columns of figures and reference codes line up neatly, but whichever you pick, keep it consistent so the finished record renders the same way in every PDF reader.
Is the signature on my invoice a legal digital signature?
It is a visual, handwritten-style mark, which suits approving an invoice or acknowledging a receipt. It is not a certificate-based or cryptographic digital signature, so if a workflow legally requires a verified certificate, use a dedicated e-signature service for that step.
