THE OLD WAY (NATIVE BIGCOMMERCE)

The "Double-Hold" Disaster

Using native BigCommerce to edit an order's final price creates a second authorization hold on your customer's credit card before the first one drops off. This locks up their funds, leads to declined transactions, overdraft fees, and angry customer support emails.

THE SOLD BY WEIGHT SOLUTION

One Clean Transaction.

We secure a safe authorization buffer at checkout. When your fulfillment team weighs the product, our app captures the penny-perfect final price and instantly releases the remaining funds. One single transaction. Zero double-holds. Total customer satisfaction.

Built for butchers, grocers, and bulk suppliers.

The Weight Station Dashboard

A dedicated, lightning-fast UI where your fulfillment team simply types in the final weights (e.g., 1.25 lbs). The app handles all complex pricing math automatically.

Automated Ledger Sync

Once the exact weight is finalized, the app automatically updates the BigCommerce order receipt and moves the status to "Awaiting Fulfillment." No manual bookkeeping.

Custom Buffer Margins

Set your own estimated weight authorization buffers per product. We recommend a 15% buffer (with a strict 25% maximum cap) to securely cover heavier cuts of meat, cheese, or fabric without shocking the customer at checkout.

Simple, Usage-Based Pricing

Pay only for the scale you need. No hidden transaction fees.

Frequently Asked Questions

Will Stripe charge me two transaction fees (one for the charge, one for the refund)?

No. Because of our advanced authorization architecture, we do not do a "Charge + Refund." We simply place a hold on the card at checkout, and perform a Partial Capture at fulfillment. Stripe only charges you one standard transaction fee on the final captured amount. The unused buffer is released back to the customer at absolutely zero cost to you.

How does the 20-order Free Trial work with my monthly limit?

Our billing is based on total monthly order capacity. You get 20 completely free orders to test the app with no time limit. If you upgrade to the Basic Plan (100 orders/month), your 20 trial orders count toward that initial capacity, leaving you with 80 remaining for your first billing cycle. On your monthly renewal date, your counter resets to a fresh 100.

Is it safe to provide my Stripe Restricted Key?

100% safe. Our app requires a Restricted Key, not a Secret Key. This means the app is strictly locked down by Stripe to only process payment captures on authorized orders. It physically cannot access your payouts, alter your bank details, or view sensitive account settings.
