Chit bridges your physical sales and your WooCommerce digital downloads. Print a code on a card, sticker, leaflet, or receipt; the customer enters the code on your site to receive access to the product’s downloadable files. Picture this for selling in person at a market – you’re selling your books but normally through webstore orders people get a PDF download too. This squares the circle.
It plugs into WooCommerce’s existing download system rather than reinventing it. When a code is redeemed, Chit creates a real (zero-total) WooCommerce order for the customer, marks it complete, and WooCommerce grants the download permissions exactly as it would for a paid order. The redemption appears in the customer’s My Account → Downloads page and in WooCommerce → Orders with a note explaining its origin.
<h4>What you get</h4>
<ul>
<li>Batch generation — generate any number of codes for a product in one go, with optional batch notes (e.g. “Christmas flyer 2025” or “Games day 2026”) so you can find them later.</li>
<li>Crockford-base32 code format — <code>CHIT-XXXX-XXXX</code>, with no ambiguous characters (no 0/O, 1/I/L, or U/V confusion) so they’re easy to read off prints.</li>
<li>Admin code browser — list table with status, batch, and product filters; sortable columns; per-row Revoke action; pagination.</li>
<li>Customer-facing redemption page — auto-created on activation with the <code>[chit_redeem]</code> shortcode. Requires login (codes are tied to user accounts so customers can re-download anytime).</li>
<li>CSV export — three-column export (code, product name, redeem URL) suitable for mail merges or label printing.</li>
<li>PDF-ready print sheet — 2×5 grid of cards per A4 page, each card showing product name, SKU, code, and the redeem URL. Uses the browser’s native “Save as PDF” so quality is excellent and there are no third-party dependencies.</li>
<li>Reports — at-a-glance counts (unused / activated / revoked) plus a top-products breakdown with activation rates.</li>
</ul>
<h4>How it integrates with WooCommerce</h4>
Chit does not maintain its own download permissions. On activation it creates a WooCommerce order on the customer’s account with the redeemed product as a line item and a $0 total, then sets the order status to completed. WooCommerce’s existing download-permission machinery takes care of the rest: the customer sees the order in their account, the download file appears in My Account → Downloads, the download counter and any expiry rules you have configured all behave normally.
