Does PDFpad add up my invoice?

No. It places text on the page exactly where you put it; there are no formulas. Check your own arithmetic.

Fill in a PDF invoice template online

An invoice is a document a business sends a customer to request payment for goods or services supplied. It shows who is billing whom, what was supplied and when, how much is owed and when it must be paid. GOV.UK notes that an invoice is not the same as a receipt, which acknowledges a payment.

If your client or agency supplies their own invoice template as a PDF, you cannot just send your own — theirs goes through their system.

Fill in the line items on screen, keep the numbers aligned, and send a flattened copy so the totals cannot be altered in transit.

Filling it in, section by section

Invoice number: GOV.UK says every invoice must have a unique identification number. HMRC’s VAT guide asks VAT invoices to carry a sequential number, so choose a sequence and keep to it.
Your details: Your company name, address and contact information. Sole traders must show their own name and any business name used, plus an address where legal documents can be delivered if they use a business name. Limited companies must show the full name as it appears on the certificate of incorporation, and if any directors are named, all of them must be.
Customer details: The company name and address of the customer you are invoicing. If the client gave you a purchase order or reference number and the template has a box for it, fill it in.
Dates: GOV.UK lists both the date of the invoice and the date the goods or service were provided (the supply date). On a VAT invoice the supply date is the time of supply, or tax point, and HMRC says a VAT invoice should normally be issued within 30 days of it.
Description and line items: A clear description of what you are charging for, with the amount for each item. On a VAT invoice, HMRC also asks for the quantity of goods or extent of services, the unit price (an hourly rate, for example) and the VAT rate on each line.
VAT details: If you and your customer are both VAT registered, you must use a VAT invoice, which shows your VAT registration number. If you trade under another name, the name and address you are registered under must appear somewhere on it. The total VAT must be in sterling, even if the rest of the invoice is in another currency.
Totals: Show the amounts charged, any VAT and the total owed. On a VAT invoice, zero-rated or exempt items must show clearly that no VAT is payable, with a separate total for them.
Payment terms: Say when payment is due and how to pay. GOV.UK says you can set your own terms; unless a payment date is agreed, the customer must pay within 30 days of getting the invoice or the goods or service. A VAT invoice must also show the rate of any cash discount offered.

Filling it in neatly

Right-align amounts so the decimal points line up.
Use a monospaced style for long reference numbers if the boxes are tight.
Check the total yourself — nothing here calculates for you.
Save a flattened PDF: an invoice with editable fields is a bad look and a worse audit trail.

Common mistakes

Reusing an invoice number, or restarting the sequence when you switch to a new template.
Leaving out the supply date because it falls in the same month as the invoice date.
Writing “consultancy” as the only description, with no dates, hours or rate.
Charging VAT without showing your VAT registration number.
Sending the invoice without saying when payment is due or how to pay.
