Practical calculators we built for custom manufacturers. Free, no signup — use them as much as you like. They use the same language and layout as Fabbric ERP, so if you ever want the full system, you already know your way around.
Build a quote the way a shop actually does: material, labor by operation, outside processing, markup, and margin — with setup amortized across the lot.
Open the estimator →Build a multi-level bill of materials — parts, sub-assemblies, and outside processing — and see the true rolled-up cost per assembly, split by supply type.
Open the roll-up →Know when to reorder and how much buffer to hold — statistical service-level or simple min/max, with EOQ order sizing and a live inventory chart.
Open the calculator →Narrow toward the right tariff heading for whatever you make — packaging, glass, textiles, plastics, metal, electronics — with links to verify on USITC. Not customs advice.
Open the finder →What imported material really costs once it clears customs — freight, duty, MPF, HMF, and fees on top of the supplier's price. The number your BOM should use.
Open the calculator →These tools are a taste of Fabbric. Each one is a small piece of the ERP, offered on its own. If it saves you an afternoon, that's the pitch — the full system does this for every project, every day.
