See what proactive
tracking wins back

Branded tracking, proactive notifications and failed-delivery
prevention. See the revenue you win back and the support cost you take out

1. Tell us about your business

Defaults are typical benchmarks. Change any value to fit your business.

2. Fine-tune the impact assumptions

Defaults are ClickPost platform benchmarks. Leave them for a conservative estimate, or match your own data.

How it works

Cut support tickets and
failed deliveries in four steps

ClickPost works the whole delivery leg — from the branded tracking page to failed-delivery recovery — so fewer orders stall and fewer shoppers write in.

div.cp-roi__hvis

Give every order a branded page

One link carries your brand and live status. Shoppers stop writing in to ask where their parcel is.

div.cp-roi__hvis (1)

Update them before they worry

A nudge on SMS, WhatsApp or email at each milestone answers the question before it gets asked.

div.cp-roi__hvis (2)

Catch exceptions early

Delivery-exception alerts flag a failed attempt or a bad address while the shipment can still be saved.

div.cp-roi__hvis (3)

Sell from the tracking page

That page pulls repeat visits. Put recommendations on it and route shoppers back to the store.

Cost anatomy

Eight factors that determine
post-purchase experience cost

Knowing what drives your delivery cost tells
you where a fix pays off first.
Frame 1618873241 (4)

WISMO ticket volume

Each "where is my order" ticket carries a loaded agent cost. Most of them never needed to exist.

Frame 1618873241 (5)

Delivery exceptions

A missed attempt sets off re-attempts, calls and, often, a return. The cost stacks quietly.

Frame 1618873241 (8)

Orders sent back before delivery

An order that bounces before it is delivered pays both shipping legs and earns nothing back. It is often the biggest hidden line.

Frame 1618873242 (1)

Carrier performance gaps

A weak carrier on a lane shows up twice: first as tickets, then as returns.

Frame 1618873241 (6)

Delivery-date accuracy

A vague or broken promise breeds anxiety, and anxiety breeds tickets and cancellations.

Frame 2147228122 (1)

Notification coverage

Anyone you cannot reach is someone who opens a ticket instead. Contactability caps the whole model.

Frame 1618873241 (7)

Tracking-page engagement

A plain carrier page throws away the repeat-visit traffic a branded one would earn from.

Frame 2147228122 (2)

Repeat-purchase capture

Traffic that lands on tracking and leaves without a nudge is revenue you simply skipped.

The math

ROI calculation formulas

Transparent methodology. These are the formulas the calculator runs. The
benchmark constants inside them come from ClickPost platform data, and you can
change every rate in the advanced panel.
Step 1
Revenue from notifications
N × AOV × 0.0035 × (engage / 60%)

Incremental orders from proactive status updates, scaled by how many shoppers you reach.

Step 2
Revenue from tracking pages
N × AOV × 0.33 × 0.1667 × 0.4359 × wcr × (0.7 + 0.5 × engage)

Repeat orders from shoppers who click back to the store from a branded tracking page.

Step 3
Failed-delivery recovery
N × fail × recovery × AOV

Orders saved when a delivery exception is resolved before it turns into a return.

Step 4
WISMO cost saved
tickets × wismo × 0.5 × cost

Support load removed, on the assumption proactive tracking clears about half of WISMO tickets.

Total ROI
notifications + tracking pages + recovery + WISMO saved
N = annual orders · AOV = average order value · wcr = website conversion rate · fail = failed-delivery rate · recovery = failed-delivery recovery lift · engage = notification engagement

It estimates two things: the support cost you save by deflecting WISMO tickets, and the repeat and upsell revenue a branded tracking page earns back. You enter your order and support numbers, and it returns an annual dollar figure for both.

Monthly orders, your average order value, the share of support tickets that are order-status questions, and your cost per ticket. If you don't have exact figures, the calculator starts with conservative industry defaults you can replace with your own.

They come from published ecommerce support and post-purchase benchmarks, set toward the low end so the output reads as a floor, not a best case. Every default is editable, so you can swap in your own data and watch the number move.

Most brands remove more than half of their order-status tickets by pairing a branded tracking page with proactive delay alerts and self-serve order edits, so customers get the answer before they open a ticket. The calculator lets you set your own deflection rate instead of assuming a ceiling.

Yes. Shoppers check tracking several times per order, and that traffic converts better than your main site, so the calculator counts the repeat purchases and upsell revenue a branded tracking page drives, on top of the ticket savings.

Most US brands launch branded tracking and self-serve returns within a few weeks using prebuilt Shopify and carrier integrations, so payback often lands within the first quarter once WISMO drops and tracking-page revenue starts. Your exact timing depends on order volume and current ticket load.
