Pay By Link — Centime-hosted one-time links for buyers without portal access.
Centime's hosted Pay by Link allows you to collect payments from customers who do not use the Customer Portal by sending them a secure, one-time payment link for a specific invoice.
Prerequisite: Merchant Services must be active on your account for Pay by Link to function and for buyer to either Pay via ACH or Credit Card.
It is designed for:
- Consumer (B2C) buyers rather than business AP teams
- Ad hoc, one-time, or project-based payers with no ongoing relationship
- Buyers in industries with lower digital sophistication who need a simpler, consumer-style payment experience
- Anyone who would not typically be onboarded to the Customer Portal
How link generation works
Pay by Link operates on a daily batch job. Once an invoice appears in the Unpaid tab, the batch job runs and generates a unique link for that invoice. The generated link then appears next to the invoice in the Unpaid tab.
Key behaviors:
- One link is generated per invoice — not per customer
- The link reflects the actual outstanding balance at the time of generation.
- Links are one-time use only
How to generate and share a payment link in the AR module

What the buyer sees on the payment page
When a buyer cis directed to the generated Pay by Link, they are routed to a Centime-hosted payment page showing:
- Invoice details and key information
- Early payment discount, if applicable
- Available payment methods (ACH, card) based on the merchant's AR settings
- Card surcharge, if applicable for the selected payment method
- ACH discount incentive, if applicable
- Payment amount field (editable or read-only — see partial payments below)
The page is optimized for both web and mobile.

Partial payments
Whether a buyer can pay partially using the payment link depends on the merchant's AR settings:
| Partial payments setting | Buyer experience |
|---|---|
| Enabled (globally or at customer level) | Payment amount field is editable. Buyer can enter any amount up to the outstanding balance. The system prevents overpayment. |
| Not enabled | Payment amount field is read-only and pre-filled with the full outstanding balance. Amount cannot be modified. |
Buyer-level payment settings and email behavior
Merchants can configure how each buyer can make payments via going to Customer Profile > Payments > Buyer Settings > Online Payment Options.
This setting directly controls which buttons appear in outbound reminder emails and monthly statements sent to that buyer, and where those buttons route them when clicked.

There are four options:
| Setting | "Access your portal" button | "Pay Now" button |
|---|---|---|
| Customer portal & Pay by link | Routes to Customer Portal (full access) | Routes to Pay by Link payment page |
| Customer portal only | Routes to Customer Portal (full access) | Routes to Customer Portal |
| Pay by link only | Routes to Customer Portal (view-only) | Routes to Pay by Link payment page |
| Disabled payments | Routes to Customer Portal (view-only) | Not shown |
**If you want buyers to have the flexibility to pay via either Pay by Link or the Customer Portal, select Customer portal & Pay by link. Statements and reminders sent to these buyers will show both CTAs i.e - "Access Your Portal" routing to the portal and "Pay Now" routing to the payment link.
