We integrate live carrier rate lookups (UPS, FedEx, USPS, or similar) into your checkout — real-time rates pulled directly from the carrier’s own API based on package weight and destination — distinct from manually configured flat-rate or zone-based shipping.
Shipping carrier live rate integration
Live carrier rates integrated at checkout, pulled directly from the carrier's own API.
- Full backup taken before we start
- If we can’t fix it, you get your money back
- We never ask for your own password
What we need from you
- An account with your chosen shipping carrier, including API credentials where required
- Accurate package weight and dimension data for your products
- Your account’s negotiated rates, if applicable, versus standard published rates
This or something else?
| You want live, real-time carrier rates integrated into checkout | This fix covers it |
| You want manual shipping zones and flat-rate methods configured, not live carrier rates | Shipping method & zone configuration errors, the manual configuration version |
| Live rates are already integrated but showing incorrect amounts | Worth describing the specific discrepancy to us directly for a diagnostic fix |
| You want a general checkout failure diagnosed, not specifically shipping rates | Checkout failure diagnosis |
What we do
- Confirm your carrier account and API access
- Verify product weight and dimension data is accurate for rate calculation
- Configure the live rate integration at checkout
- Test rate accuracy across a range of package sizes and destinations
- Verify negotiated rates apply correctly, if applicable
What is included
- Live carrier rate integration configured at checkout
- Verified rate accuracy across a range of test scenarios
- Confirmation negotiated rates apply, if applicable
- A written note on the configuration
Not included
- Setting up manual, flat-rate, or zone-based shipping — a separate, related fix if that’s actually your need
- Your carrier account itself, or any associated cost, which remains yours directly
- Correcting inaccurate product weight or dimension data across your whole catalogue — a separate, larger data-quality task if extensive
- Ongoing management of your carrier account or negotiated rates
Questions about this fix
Why would I want live rates instead of a flat shipping fee?
Live rates ensure you're charging (and being charged) an accurate amount based on actual weight and destination, rather than over- or under-charging with a flat rate that doesn't reflect real shipping cost.
Do I need accurate weight data on every product for this to work?
Yes, accurate weight and dimension data is essential for live rates to calculate correctly — if this is missing or wrong across many products, that's worth addressing as part of this setup.
Will my negotiated carrier rates show instead of standard published rates?
If your account has negotiated rates and the carrier's API supports returning them, we'd configure this to reflect your actual rates rather than standard published pricing.
What if I want multiple carriers offered at checkout?
This is possible depending on your plugin's capabilities — we'd confirm whether you want customers to choose between carriers or see a single, unified rate.
Does this replace my existing shipping zone configuration entirely?
Not necessarily — live rates and zone-based methods can often coexist, for example live rates domestically and a flat international rate, depending on what you need.

If this is the second time this year
A bad update breaking the site is a symptom of updates not being tested first. Care plans run every update on a staging clone before it reaches your live site, which is the actual fix for this happening again.
Your access, your rules
Create a separate admin account for us and delete it when we are done. For anything else, we get in touch and agree a method — never a form field on this site, never by reply to an email.
We back up first, always
Before anything is touched we take a full backup and keep it for 30 days. If a fix goes wrong, we put the site back exactly as it was.
If it is not what you bought
If the problem turns out smaller than what you ordered, we refund the difference. If it is bigger, we stop and send a quote before doing any extra work.
If we cannot fix it
You get back what we received. Diagnosis is on us — you only pay when the problem is actually solved. The payment processor takes its fee before the money reaches us, so we never hold it and it is not ours to return. That is true here as everywhere else.
If it comes back
Reply within seven days of delivery and we put it back on the bench at no cost. The fix is not finished until it holds.
What we are responsible for
If something goes wrong with a fix, our responsibility is limited to what you paid for it. We take a full backup first so mistakes can be undone, and we tell you before doing anything outside what you bought.
