A comprehensive soap inventory spreadsheet should cover the full production cycle — from raw materials to finished bars. At a minimum, it should include:
- Material Inventory:
- A master list of all materials — carrier oils (coconut, olive, palm, castor, shea butter), lye (sodium hydroxide for bars, potassium hydroxide for liquid), fragrance oils, essential oils, colorants (micas, oxides, natural colorants), additives (clays, oatmeal, botanicals), molds, packaging. For each material, track on-hand quantity, unit cost, tracking unit (oz, lb, g), and preferred vendor.
- Purchase Tracking:
- A log of every material purchase with date, vendor, quantity, cost, shipping, and tax. This gives you a full expense history and helps you calculate landed costs.
- Production Log:
- Record each soap batch you make. List what soap you made, what date you made it, and what materials you used. This is how you calculate cost per bar and track material depletion.
- Finished Soap Inventory:
- Track your ready-to-sell bars by product, quantity on hand, unit price, and manufacture cost. This is your finished goods inventory value.
- Sales/Orders:
- Log every sale with order date, product, quantity, price, and manufacture cost. This gives you revenue, COGS, and gross profit per sale.
- Reports:
- Calculated totals for revenue, expenses, COGS, inventory values, and profit. These are the numbers you need for taxes and to understand if your business is sustainable.
Beyond the basics, soap makers benefit from tracking superfat percentages, cure dates, batch numbers (for traceability), and recipe notes. This helps maintain consistency and troubleshoot issues when a batch doesn't turn out right.
