Who this is for
- Businesses replacing mailed checks with bank transfers
- Owners deciding whether ACH is enough for supplier payments
- Teams that occasionally need urgent or international payments
- Bookkeepers trying to standardize vendor payment methods
Core steps
- Confirm whether the vendor accepts ACH, wire, card, or check before choosing a method.
- Use ACH for recurring domestic payments to known vendors because it is designed for scheduled payments between bank accounts.
- Use wires when timing or vendor requirements justify the extra cost and operational care.
- Double-check routing and account information before sending any bank transfer.
- Keep the invoice, approval note, confirmation number, and accounting record together.
Price and cost notes
ACH is often less expensive than wires, but your bank or software provider sets the actual fee. Wires usually cost more and may have incoming and outgoing fees. Bill pay tools may bundle ACH, checks, card funded payments, and delivery options differently, so check official pricing before choosing a workflow.
Pros
- ACH works well for predictable domestic bills
- Wires can be useful for urgent or international vendor payments
- Both methods reduce paper check handling
- Bank transfer records can be easier to reconcile than cash or informal payments
Cons
- ACH is not always instant, even when same day options exist
- Wires can be expensive and harder to reverse
- Bank detail fraud can affect either method
- International wires may involve intermediary bank fees
Next step
Review last month of vendor payments and tag each one as ACH, wire, check, card, or other. That map usually shows where the workflow should change first.
