Help & FAQ

Open the Invoice Link app and tap the + button on the home screen. Enter the customer's name and email (or pick them from your contacts), add line items with prices, and tap Send. Your customer gets a secure pay link by email or SMS — they don't need to download an app to pay you. Most contractors send their first invoice in under a minute.

Online card and bank (ACH) payments are available to businesses in the United States and are processed by Stripe. When your customer pays, the funds settle to your connected Stripe account on Stripe's standard payout schedule (daily or every 2 business days for most U.S. accounts). Standard processing fees apply: 2.9% + $0.30 for credit/debit and 0.8% capped at $5 for ACH. Invoice Link also keeps a 1% + $0.30 platform fee on each payment processed through the app. You can absorb these fees or, where the law allows, pass them to your customer as a processing fee. Card surcharges aren't allowed in Connecticut, Massachusetts, or Maine, and debit-card and ACH payments can't be surcharged. In every country — including Canada, the United Kingdom, Australia, and New Zealand — you can send invoices and estimates, show your customer your own payment instructions (who to make a check out to, bank-transfer details, or your PayPal address), and record cash, check, and bank-transfer payments for free.

Open the Payments tab in the app, find the payment, and tap Refund. You can refund the full amount or a partial amount. The refund flows back through the processor that handled the original payment. For card and bank payments through Stripe, your customer automatically gets a refund confirmation email. Refunds typically take 5–10 business days to land back on the customer's card. The 1% + $0.30 platform fee and the processor's fee aren't returned on refunds.
