Using ACH Debits to Collect Invoice Payments

Overview

ACH Direct Debit lets you pull funds directly from your customer's bank account when they pay an invoice—no more waiting for them to initiate a transfer.

How It Works

1. Create an invoice and enable ACH Direct Debit as a payment option
2. Your customer connects their business bank account and authorizes the payment
3. Funds are automatically pulled from their account and deposited into yours

Enabling ACH Debit on an Invoice

When creating or editing an invoice, go to the Payment Details section:

1. Under Supported payment methods, check the box for Direct ACH debit
2. Review the fees (1% + $3 per transaction) and processing time (2–5 business days)
3. Click Limits to see your current transaction limits

You can enable both Manual Transfer and Direct ACH Debit on the same invoice to give your customer flexibility.

What Your Customer Sees

When your customer opens the invoice, they'll see ACH Direct Debit as a payment option. To pay:

1. Connect a business bank account via Plaid
2. Authorize Slash to debit their account
3. Click Pay

Note: Only business bank accounts are supported. Consumer accounts cannot be used for ACH Direct Debit.

Auto-Pull from Saved Accounts

If your customer has previously connected their bank account, you can automatically initiate the payment when you send the invoice:

1. On the invoice review page, check Automatically pull funds from connected account. This option will only appear if the customer has a connected bank account already.
2. When you send the invoice, the payment will be initiated automatically

Your customer will receive an email confirming the payment has been initiated.

Additional Information

Transaction Limits

ACH Direct Debit has the following default limits:

• Per transaction: $10,000
• Daily: $50,000
• Weekly: $200,000

If your invoice amount exceeds your single transaction limit, you'll need to lower the amount or contact the Slash support team to request a limit increase.

Fees

• Initiation fee: 1% of the invoice amount + $3 flat fee
• Return fee: $10 (if the payment is returned)

Fees are deducted from the payment before funds are deposited into your account.

Processing Timeline

1. Day 1–2: Payment is initiated and held by the bank (standard ACH return window)
2. Day 3–5: Slash holds funds for security review
3. Day 5+: Funds are released to your account and the invoice is marked as paid
