One shipping system for your Miva orders, from checkout to delivery.
Postsale is a browser-based shipping and order management system that connects directly to your Miva store. Orders sync automatically as they are placed, and stay up to date through delivery. When you print a shipping label in Postsale, tracking numbers and fulfillment status push back to Miva and your customer is notified. No manual updates and no disconnected workflows.
Company Overview
Postsale helps merchants manage shipping, orders, and customer communication in one system. Compare rates across USPS, UPS, and FedEx, print labels individually or in batch, and keep order status aligned across your store and carriers.
Every plan includes optional Shipsurance shipment protection, returns management, branded emails, packing slips, and invoices. USPS ships at discounted commercial rates, and you can use your own UPS and FedEx accounts. If you have a negotiated service agreement (NSA) with USPS, those rates apply in Postsle at no additional cost.
Plans range from $9.99 to $169.99 per month based on shipment volume, with no per-label software fees. Start with a 14-day free trial and reach a real person on our support team from day one.
Key Features
- Real-Time Miva Sync: Orders sync automatically as they are placed, and you can import up to 7 days of order history when you first connect. When you ship, tracking numbers and fulfillment status update in Miva and notify your customer automatically. Our team is available to help with setup if needed.
- Ship From Any Device: Postsale runs in your browser on desktop, tablet, and mobile. Bulk ship from your desk, check order status from the warehouse floor, or handle a rush order from your phone. No software to install or app to download. Just log in and ship.

- Batch Printing, Branded Documents, and Automation: Every plan includes batch label printing, shipping presets, and branded shipping confirmation emails, packing slips, and invoices. Print labels for multiple orders at once and send customers professionally branded communications automatically. On Expand plans ($59.99/mo) and above, build automation rules to match carriers and service levels based on weight, destination, value, or product type, and flag orders that need review.
- Discounted USPS Rates and Your Own Carrier Accounts: Connect your USPS Business account to ship at discounted commercial rates on Ground Advantage, Priority Mail, and Priority Mail Express. USPS cubic pricing is applied automatically when your package qualifies. Connect your existing UPS and FedEx accounts to use your negotiated rates. Compare rates across all carriers and services before printing each label.
- Postsale Anywhere: Ship orders from anywhere using Postsale's Chrome extension, even outside your Miva store. Open Postsale on any webpage to capture order details, compare carrier rates, and print labels without leaving your workflow. Manage shipments from Miva and non-Miva sources in one place, including wholesale orders, customer emails, marketplaces, or custom workflows.
- Built-In Shipment Protection: Every Postsale plan includes access to Shipsurance coverage. Protect domestic and international shipments at rates significantly lower than purchasing insurance directly from carriers. Coverage is billed weekly with no monthly minimum. File claims directly within Postsale.
- Human Support From Day One: Every Postsale plan includes real human support, including during the 14-day free trial. Whether you need help connecting your Miva store, configuring shipping presets, or troubleshooting a carrier issue, our team responds directly. We also offer hands-on setup assistance for Miva merchants who want guided help getting their store connected.
