Use a PayPal invoice when the buyer, amount and terms are specific to one sale. Use a payment link when the same offer or open amount needs to be shared repeatedly. Use checkout when buyers select products, quantities or options before paying.
All three can end in a PayPal payment, but they solve different steps before payment. Choosing from the buyer's job prevents a common conversion mistake: sending an empty amount link for a detailed project, or forcing a returning customer through a full catalog for one known invoice.
The One-Minute Decision Matrix
| Question | Invoice | Payment link | Checkout |
|---|---|---|---|
| Is the buyer already known? | Usually yes | Optional | Usually no |
| Is the amount customer-specific? | Strong fit | Possible with an open/custom amount | Requires configured pricing or quote logic |
| Is the link reused? | Normally no | Usually yes | Yes |
| Are formal line items and due terms needed? | Strong fit | Weak fit | Order summary rather than receivable terms |
| Does the buyer choose products or quantity? | Seller prepares them | One focused offer works well | Strong fit |
| Best channel | Direct email to the customer | Email, chat, social, QR | Website, store or hosted product page |
| Record created before payment | Invoice/receivable | Link or request | Cart/order |
PayPal's own Invoicing overview makes a similar distinction between customer-specific invoices and shareable payment links. The missing decision is what must be known before the buyer clicks.
Choose an Invoice for a Known Obligation
An invoice is appropriate when you have already agreed who owes what. It can contain the customer's details, numbered line items, taxes, issue and due dates, purchase-order reference, notes and payment terms.
Use it for completed freelance work, a project deposit, a wholesale order or a recurring B2B service where both sides need a record. The seller creates the obligation first; payment settles it later.
An invoice is not automatically legally or tax compliant simply because software generated it. Required fields, numbering, retention and VAT treatment depend on jurisdiction. Keep the commercial agreement and evidence of delivery with the invoice record.
Choose PayRequest invoicing when you want the invoice and customer record in the same billing workflow while allowing supported payment-provider options.
Choose a Payment Link for One Clear Action
A payment link is a shareable URL that opens a hosted payment step. PayPal describes its Payment Links as suitable for email, text, social media or QR sharing without a website or code.
It works best when the page has one obvious action: pay a €75 deposit, buy one workshop seat, donate an amount or pay the balance already explained in the conversation. A reusable link is especially effective when the offer and price stay the same across buyers.
The link still needs context. Include the seller identity, description, price and currency, delivery timing, policies and contact route on the hosted page or immediately before it. Do not ask buyers to infer what an unexplained URL charges.
Use PayRequest payment links when you want a branded, trackable page that can connect PayPal and other supported providers without building checkout code.
Choose Checkout When the Buyer Builds the Order
Checkout belongs after product selection. It is the right path when buyers choose among items, variants, quantities, shipping options or add-ons. The order is not fully known until those choices are made.
A checkout should preserve the product and price context, calculate the order consistently, collect only necessary information and show the available payment methods at the right moment. PayPal's developer overview separates links, buttons, invoices and QR options because the selling surface matters before the wallet opens.
Use a hosted PayRequest payment page or digital-product page when you need an offer page and checkout rather than only a processor button.
Score the Sale Before Choosing
Give one point to the format under each answer.
| Selling fact | Point goes to |
|---|---|
| Customer name and billing details are already known | Invoice |
| Price or scope differs for this customer | Invoice |
| Due date, PO number or formal line items matter | Invoice |
| The same focused offer will be shared many times | Payment link |
| The link must work in social, chat or a QR code | Payment link |
| The buyer may enter or select one amount | Payment link |
| The buyer chooses between several products | Checkout |
| Quantity, variant, tax or delivery changes the total | Checkout |
| An order and fulfilment step must follow payment | Checkout |
The highest score gives the default. A tie often means two stages are being confused. For example, a custom service can use a public checkout to collect a discovery deposit, then a customer-specific invoice for the approved project balance.
Four Real Online-Selling Workflows
Send an invoice with the client's legal details, agreed milestone, due date and reference. Let the client pay through the supported option in the invoice. Do not reuse it for another customer.
Publish one payment link for a fixed-price seat. The page states date, time zone, capacity, cancellation policy and what the attendee receives. Share the same link in the profile, post and email.
Use a product page and checkout because the buyer must see previews, file format, license and delivery terms before choosing. Release the file only after a verified successful payment—not from a screenshot sent in chat.
Use a focused payment link for a standard non-refundable booking deposit if the terms are identical. After scope approval, send a named invoice for the remaining amount and attach the agreed deliverables or reference.
Where PayPal Business Fits
PayPal is the processor and buyer payment option; invoice, link and checkout are the presentation and record layers. PayRequest's PayPal partner connection requires a PayPal Business account. An eligible Personal account can be converted during onboarding.
PayRequest includes every standard feature on the Free plan and charges 2% per successful payment, capped at €25 per transaction, in addition to PayPal's processing fee. Compare the total workflow and cost, not only whether creating a link or invoice has an upfront charge.
Conversion Checklist for Every Format
- Match the headline to the exact offer or obligation.
- Show price, currency and tax treatment before the final payment action.
- Make the seller name and support contact recognizable.
- Put delivery, cancellation, return or refund terms before payment.
- Remove fields that are not needed for fulfilment or compliance.
- Test on mobile from the channel where the link will be shared.
- Confirm the success page tells the buyer what happens next.
- Reconcile a verified payment event, not a screenshot or email alone.
- Test refunds and failed payments before launching at scale.
The right format reduces explanation. Invoice a known customer, link one clear action, and use checkout when the buyer must build an order. Then connect the payment provider that your audience trusts and test the complete journey—not just the PayPal button.
