BLNDR is the candle shop OS — pitcher math, batch costs, recipe management, vendor catalog cross-reference, inventory tracking, and Square / Shopify sync. The six steps below are the actual day-to-day workflow. Each links to its dedicated section in the sidebar for the full deep-dive.
1. Set up your shop (Settings)
One-time setup. The Batch Planner pulls everything from here, so this drives accurate cost-of-goods downstream.
- 1
Add the waxes you actually buy
Settings →
MY WAXES. Vendor + size + real price paid (not list price). This drives$/lbCOGS in the Batch Planner. - 2
Save a formula preset
Settings →
MY FORMULAS. A formula is a (wax + fragrance load %) pair you reuse. Star one as default; switch per batch via dropdown. - 3
Add wicks + lids
Settings →
WICKSandLIDS. Per-unit cost + owned qty. Add these before containers — the container form's default-wick + default-lid dropdowns pull from these registries. - 4
Build your container catalog
Settings →
CONTAINERS. Jar/tin sizes with capacity, cost, sell price, default wick + lid (selected from the wicks/lids you just added), plus stock tracking and refill mode. - 5
Connect Square + Shopify (optional)
Settings → integrations cards. OAuth-based; tokens are AES-256-GCM encrypted at rest. Sign into the Shopify Admin BEFORE clicking CONNECT or Shopify shows “Unauthorized Access”.
2. Stock your library
Library → Oils. Browse the catalog (~6,000 oils across CandleScience, The Flaming Candle, Nature's Garden, Wholesale Supplies Plus, Hive & Honey). Add the ones you own. Library oils appear first in the mixer search, drive Oil Engine tracking, and feed the Batch Planner's stock check.
(i)for the full panel: per-size price table, IFRA cert + SDS, manufacturer (sub-brand), “view on vendor” link, classifier confidence.3. Build a recipe (Mixer → Recipes)
Slider-based blend builder. Add oils from your library, drag percentages to total 100%, get hazard + load-band guardrails, name it, save it. The recipe lands in My Blends with version history.
4. Plan a batch (Batch Planner)
Pick recipe + ratio + containers + quantities. The Live Math panel returns wax weight, per-pitcher oil split, COGS breakdown, margin, and a stock check — all without a Calculate button.
5. Make and ship (Make Batch)
Sticky footer button. Click → confirm the manifest → recipe-history snapshot is taken, library qty deducts, finished candles push to Square (and Shopify, if enabled). Stock-short batches don't block — the button switches to MAKE ANYWAY because your Frag Lab inventory is the source of truth.
6. Maintain (Inventory + Oil Engine)
Day-to-day cleanup. Drag-to-adjust quantities, run the Oil Engine dialog when vendors discontinue oils or you have cross-vendor duplicates. Swapped oils stay in your library with a “swapped → X” badge until stock hits zero.
