Introduction


Precise Petcare can connect to a variety of merchant gateways for credit-card, ACH, PayPal, and Venmo payments. We never add a surcharge—only the processor’s own fees apply. All configuration happens under Billing › Billing Settings › Online Payments.

Gateway overview

  • Integrated – Stripe, PayPal Pro, Authorize.net / eCheck.net, Stax, Paya, Payeezy, QuantumGateway, and Sage Pay keep the client on your portal.

  • Off-site – PayPal Standard / Advanced and Venmo redirect the client to an external page or app.


Details for each gateway appear below.

Off-site gateways


PayPal Standard / Advanced

  • In PayPal Standard (off site) enter either your PayPal account email or PayPal Merchant ID (Merchant ID uses PayPal Checkout pop-up).

  • Clients click Pay Now on the printable invoice and complete payment at PayPal.

  • PayPal Standard is free; Advanced is $5 / month. One invoice, full balance only.


Venmo

  • In Venmo (off site) enter:

    • Venmo Username – displayed to desktop payers.

    • Venmo QR Link – used by mobile payers.

  • A Venmo button appears on invoices; the client types the amount manually.

  • Remember: record the payment afterward (see Manual Check/Cash Payments & Credits).

Integrated gateways


Integrated options add a Make Payment button that opens the in-system Payments page. Clients can pay multiple invoices, make partial payments, and add tips. Log-in is required unless you ask Support to enable guest access (guests cannot store cards).

Best-practice tips

  • Always test with a small charge after entering new credentials.

  • Automatic discounts and surcharges still apply—the gateway choice does not affect pricing.

  • Guest payments (no log-in) disable card-on-file features; use only if necessary.

  • Switching processors removes stored cards—notify clients before migrating.

  • Venmo payments must be logged manually in Billing › Transactions.
