Key takeaways
- Authorize the full order at checkout, then capture only what ships in each package and release any amount you won't charge.
- Authorization lifespans vary by card brand, transaction type and merchant category, so confirm current windows with your processor before you build a backorder policy around them.
- Gateways differ on partial and multiple captures, so test the exact sequence of capture, reauthorization and void before you rely on it.
- Clear confirmation and shipping emails that explain separate charges prevent "charged before shipped" and "charged twice" disputes.
When one order leaves your warehouse in two or three boxes, your payment flow has to keep up. A partial capture split shipment workflow lets you authorize the full order once, then charge the customer only for what actually ships, package by package. Done well, it keeps you clear of card network expectations and avoids confused customers. Done poorly, it leads to expired holds, duplicate pending charges and disputes that claim you billed before you shipped. This guide covers how authorization and capture work, how long holds last, which gateway features to look for, and how to set up Shopify, WooCommerce and BigCommerce.
Authorize and Capture in Ecommerce: What Happens When a Customer Clicks Buy
Every card payment has two stages, even when they look like one.
- Authorization: Your gateway asks the card issuer whether the card is valid and has enough available credit or funds. If the issuer approves, it places a hold on that amount. No money moves yet.
- Capture: You tell the gateway to collect some or all of the authorized amount. Captured transactions go into your settlement batch, and the funds move toward your bank account.
Many stores use "authorize and capture" (often called a sale) at checkout, which charges the full amount immediately. That is simple, but it means you collect money for items that may not ship for days or weeks.
The alternative is authorize only at checkout, then capture at fulfillment. This matches what many customers expect, which is to be charged when the item ships. It also lines up with card network guidance that discourages charging for physical goods long before they ship. The tradeoff is that you now have to manage the timing of each capture.
If you're still setting up the basics of your store's payment stack, our guide to setting up ecommerce payment processing for your online store covers gateways, merchant accounts and checkout flow.
Authorization Expiration on Online Orders: How Long a Hold Lasts
An authorization does not last forever. After a set period, the hold becomes stale, and capturing against it may fail, cost you more, or expose you to chargebacks if the issuer later disputes the charge.
Exact validity periods depend on several factors:
- Card brand: Visa, Mastercard, American Express and Discover each set their own rules, and they have revised them over time.
- Transaction type: A standard ecommerce authorization may be treated differently from an estimated or incremental authorization in certain industries.
- Merchant category code (MCC): Some categories, such as lodging and car rental, have historically had longer windows than general retail.
- Issuer behavior: The cardholder's bank may drop the pending hold from the customer's online statement before the network validity period ends. The customer then sees the charge "disappear," and a later capture can look like a surprise.
We're not listing day counts here because those figures change. Ask your processor for the current windows that apply to your account. Use this checklist:
| What to Confirm | Why It Matters |
|---|---|
| Authorization validity for each card brand you accept | Sets your maximum safe gap between checkout and final capture |
| Whether late captures are allowed and what they cost | Some late captures still go through but may face higher fees or weaker chargeback protection |
| Whether your gateway auto-voids old authorizations | Prevents stale holds from lingering or being captured by mistake |
| How your MCC affects authorization rules | Your category may have different rules than you assume |
Build your backorder policy around the shortest window among the card brands you accept, not the longest.
Partial Capture for Split Shipments: Which Gateways Support It
Two related features matter here, and gateways don't all handle them the same way.
Partial Capture
A partial capture collects less than the authorized amount. For a single shipment with an out-of-stock item, you capture the shipped portion and release the remainder.
Multiple Captures on One Authorization
Multiple captures (sometimes called multi-capture or split capture) let you capture against the same authorization more than once, typically once per shipment, until you reach the authorized total. This is the cleanest setup for split shipments because the customer sees one authorization and you charge each box as it ships.
Some gateways allow only a single capture per authorization. On those gateways, the first partial capture closes the authorization and releases the remaining balance. For the second shipment, you need a new authorization.
Ask your gateway or processor these questions:
- Can I capture less than the authorized amount?
- Can I capture more than once against a single authorization? If so, is there a limit on how many?
- What happens to the uncaptured balance after a partial capture? Is it released automatically, or do I need to void it?
- Does my ecommerce platform's integration expose these features, or only the gateway's own dashboard?
That last question catches many merchants. A gateway may support multi-capture, but your shopping cart plugin may only send a single full capture. MannyPay offers payment gateways for online stores, including Authorize.net and NMI connections, and its team can help you confirm which capture behavior your setup supports.
A compliance note: Capturing per shipment against an order the customer already placed is a legitimate, expected practice. Splitting one sale into several smaller transactions to get around a decline, an approval limit or a processing restriction is not. Card network rules prohibit it, and it can put your merchant account at risk.
Backorder Payment Capture Without a Second Checkout
Backorders are where split shipments get tricky. Here is an illustrative example.
Illustrative example: A customer places a $180 order. The $120 item is in stock. The $60 item is backordered for an unknown length of time.
- At checkout: Authorize $180.
- At first shipment: Capture $120. If your gateway supports multiple captures and the backorder will clear well within the authorization window, leave the remaining $60 open.
- If the backorder will take longer: Release the $60 rather than holding it. A hold the customer can see on their statement for weeks causes support tickets and can lead to disputes.
- When the item arrives: Charge the $60 without making the customer check out again.
For step 4, there are a few common approaches:
- Stored credential with consent: If the customer agreed at checkout to let you store their card and charge it when backordered items ship, you can process a new authorization. Flag it correctly as a stored-credential transaction. Your checkout language should spell out this consent.
- Payment link: Email the customer a secure link to pay for the backordered item. This adds a step for the customer but reconfirms their intent.
- Cancel and refund option: Give the customer a clear option to cancel the backordered item at no charge.
Before you settle on a policy, check the shipping rules that apply to you. U.S. federal trade rules set expectations about shipping within the timeframe you advertise and notifying customers about delays and their option to cancel. This is general information, not legal advice. Confirm your specific obligations with a qualified professional.
Reauthorizing After an Expired Hold Without Causing Declines
Sometimes an authorization runs out before the last package ships. Reauthorizing is routine, but it can create problems if you do it carelessly.
Do It in the Right Order
- Void or reverse the old authorization if any portion is still open. This prevents the customer from seeing two holds for the same item.
- Run a new authorization for only the remaining amount, using the stored credential the customer agreed to.
- Capture at shipment as usual.
Avoid Retry Storms
If the new authorization is declined, don't keep resubmitting the card. Card networks have rules on repeated retries of declined transactions, and excessive attempts can bring extra fees and attract scrutiny to your account. Instead:
- Check the decline reason your gateway returns.
- Contact the customer with a payment link if the card has expired or was replaced.
- Use an account updater service where available. Our explainer on keeping stored cards current with a card account updater covers how these services work.
Unexpected declines on a returning customer's card can also come from fraud filters tuned too tightly. If this happens often, read our guide on why good customers' cards get declined at checkout.
Order Confirmation Emails That Explain Separate Charges
Most split-shipment disputes start with confusion, not fraud. A customer sees $120 posted, then $60 a week later, and assumes they were billed twice. Good emails head this off.
In the order confirmation:
- State that items may ship separately and that each shipment is charged when it ships.
- Explain that a temporary hold for the full amount may appear on the customer's statement.
- If you store the card for backorders, restate what the customer agreed to.
In each shipping confirmation:
- List the items in that box and the amount charged for them.
- Include the tracking number.
- Show what remains to ship and the expected charge.
Illustrative wording: "Your first package is on its way. We charged $120.00 for the items in this shipment. Your remaining item ($60.00) is backordered, and we'll charge your card only when it ships. You can cancel it anytime before then."
Keep a record of tracking for each capture. If a dispute claims non-delivery for one package, you'll need proof tied to that specific charge. Our article on winning disputes on supplier-shipped orders explains how to organize that evidence. Make sure your billing descriptor matches your store name, too, so customers recognize every charge.
Platform Settings to Check in Shopify, WooCommerce and BigCommerce
Menu labels and options change, and what you can do often depends on the gateway connected to your store. Use these as starting points, then confirm in your current admin and with your gateway.
| Platform | Where to Look | What to Verify |
|---|---|---|
| Shopify | Payment capture settings in your payments admin | Whether you capture at checkout, at fulfillment or manually, and whether your gateway supports partial captures from the order page |
| WooCommerce | Your gateway plugin's settings | Whether there is an "authorize only" or "capture later" option and whether partial captures sync back to the order |
| BigCommerce | Your payment gateway's transaction type setting | Authorize-only versus authorize-and-capture, and how partial captures are handled on orders |
Some practical notes:
- Shopify: Capturing automatically when an order is fully fulfilled may not suit split shipments. Test how your store behaves when only part of an order ships. MannyPay supports a Shopify payment integration if you're reviewing processing options.
- WooCommerce: Capture behavior lives in the gateway plugin, so features vary widely. Our checklist for choosing a WooCommerce payment gateway covers what to ask. See also MannyPay's WooCommerce integration.
- BigCommerce: Confirm whether capture actions in the BigCommerce admin pass through to your gateway or need to be done in the gateway dashboard. Review MannyPay's BigCommerce integration for connection options.
Whatever platform you use, run a test order end to end: authorize, partially capture, wait, capture again or reauthorize, then void the remainder. Then compare the results in both your platform and your gateway.
Next Steps for Your Store
Split shipments don't have to cause billing problems. To recap:
- Authorize at checkout, capture at shipment.
- Confirm current authorization windows with your processor.
- Know whether your gateway supports partial and multiple captures, and whether your platform passes them through.
- Release holds you won't use, and get clear consent before charging stored cards for backorders.
- Explain each charge in your emails.
