The revenue leak

You spent to win the order. Post-purchase is where you lose the customer

WISMO floods the queue

Refunds bleed revenue

Every instant refund is money and a customer walking out the door for good.
Wasted tracking traffic

Wasted tracking traffic

Shoppers check tracking 3-4 times per order, on a carrier’s page that sells them nothing.
One-and-done buyers

One-and-done buyers

Without a reason to return, first-time buyers never become repeat customers.
No personalization

No personalization

Every customer gets the same generic post-purchase flow, regardless of value or history.

Post-purchase that plugs into
your existing stack

  • 600+ Carrier Partners
  • 75+ Communication Gateways

You set rules on cost, speed, zone, and service level. For each order, ClickPost scores eligible carriers against those rules and allocates the best fit in milliseconds, with automatic failover if a carrier is down.

You do. Your carrier contracts, negotiated rates, and billing stay directly between you and the carriers. ClickPost's role is the intelligence on top: it connects to your carrier accounts over API, recommends the best carrier for each shipment based on cost, speed, SLA, and destination, and tracks it end to end. It reads your rates to make that recommendation, but it does not set, negotiate, or bill them.

Address verification catches bad or incomplete addresses before dispatch, and real-time exception handling reattempts failed deliveries, cutting returned-to-sender volume by up to 40%.

Apex pulls carrier performance, SLAs, exceptions, and cost anomalies into one live dashboard, with SLA-breach and cost alerts the moment they happen. Reports export for finance, so decisions run on real data instead of last week's spreadsheet.

ClickPost connects to Shopify, major OMS and WMS platforms, and custom stacks via API, so it slots into your current workflow rather than replacing it.

UPS, FedEx, USPS, DHL, and 600+ carriers, plus major regional and last-mile providers, all through one integration.

Post-purchase touches every team.So does ClickPost

The same platform your support, ops, and growth teams share, each with the view and controls they need

Turn every post-purchase moment into revenue

Tracking-page upsells, exchange-first return flows, and post-purchase campaigns that drive repeat purchases.
