Understanding billing and payments

The ShipWave shipping core has no monthly subscription, no per-label fees, and no minimum volume requirements—you only pay for the labels you purchase, and the rate shown at checkout is the price you pay (carrier re-weigh adjustments, when they happen, are passed through with an email notice). Optional add-on modules bill monthly at the prices listed on shipwave.app/pricing.

For individual checkout, ShipWave authorizes the selected label amount through Stripe before carrier purchase. Approved high-volume business accounts prefund an organization shipping balance with a customer-initiated ACH or wire. Every external business label purchase—batch, quick ship, API, auto ship, split, replacement, supplier, or quick letter—debits the customer-facing price from posted funds immediately before carrier purchase while preserving the required reserve.

Carriers sometimes adjust charges after a package is delivered. Common reasons include: weight corrections (the carrier measured a different weight than declared), address corrections (the carrier had to correct an invalid ZIP code), and dimensional weight overrides. ShipWave monitors for these adjustments and notifies you if your account is debited or credited.

Approved business accounts receive Mercury virtual-account instructions and can send ACH or wire from their own bank. The Billing page separates account funds, the nonspendable reserve, available-to-spend funds, pending transfers, and past due. ShipWave does not store or display full routing or account numbers and does not initiate automatic bank pulls.
