How to build a COA binder for a hemp retail store

Updated October 21, 2026

A COA binder is a simple file that holds one lab report for each product and lot a store carries. It sits at the counter, so staff can pull the right report quickly.

The routine is short. Save or print the report, file it by product and lot reference, and swap it out when new stock arrives. When a report and a package do not line up, ask the supplier.

Why a store keeps a COA binder

Customers and staff ask to see lab reports for retail products. A binder answers that request without a phone search. It also shows which shelf items have a report on file and which still need one.

The binder is a store practice. It does not replace reading each report before stocking. For that step, see How to read a COA before you stock a hemp product.

One record per product and lot

The core rule is one record per product and lot reference. A matching product name on its own is not a match. Two packages of the same strain can come from different lots with different reports.

Product name as printed on the package
Product format, such as gummies, live rosin or uncoated flower
Lot or batch code from the package
Lot or sample reference from the report
Date the report was filed

A laboratory sample reference is not always the same number as the batch code on a package. Write both on the record so staff can see how they connect.

Where Zigg Distro links lab reports

Zigg Distro places a lab report link inside the product description on the product pages that carry one. Open the product page, scroll to the description and look for the link.

For example, a buyer stocking Breath Mintz THCA Live Rosin checks that page's description. The same goes for jars on the wholesale live rosin page and products in the Gummies category.

A product with no report published on the site is not a product without a report. Ask Zigg Distro for it through the contact page.

How to organize COAs: save, print and file

Download the report as a file and name it with the product and lot reference.
Store the file in one shared folder, sorted by product format.
Print a copy for the binder.
Write the package lot code on the printout.
File it behind a tab for its format, in alphabetical order.
Add a line to the binder's index page.

Tabs by format match how many stores shelve stock. A clerk holding a gummy goes straight to the gummy tab, then to the product name.

Replace the report when a new lot arrives

A new lot means a new record. When a delivery carries a lot code that differs from the one on file, pull the matching report and file it.

Keep the old report until the last package from the old lot leaves the shelf. Then move it to an archive folder. Shelves often hold two lots at once during a changeover, so the binder should too.

A binder at the counter, and what to do when things do not match

Keep the binder behind the counter, within reach of the register. When a customer asks, staff match the package lot code to the record and show the report.

Sometimes the name, format or lot reference on a report does not line up with the package. A published report is not by itself proof that it covers the lot in hand. Set the product aside and ask the supplier before filing anything.

Train staff on this step. The guide on smoke shop employee training covers handling product questions at the counter.

Questions and answers

What goes in a COA binder?

One printed lab report per product and lot, each marked with the package lot code. An index page at the front lists every record. Tabs by product format make lookups fast.

Where are Zigg Distro lab reports?

Zigg Distro places a lab report link inside the product description on product pages that carry one. If a page has no link, ask Zigg Distro through its contact page.

Should a store keep old lab reports?

Keep the old report until the last package from that lot sells. Then move it to an archive folder. This keeps the binder accurate during lot changeovers.

What if the lot number on a report differs from the package?

A lab sample reference is not always the same number as the package batch code. Check the product name and format too. If they still do not line up, ask the supplier.

Is a digital file enough, or does a store need paper?

Many stores keep both. A shared folder holds the files, and a printed binder at the counter works when the register screen is busy or offline.
