Bill of Materials, built into your Business Operating System

One parts list, many levels

Every product carries its bill of materials, including sub-assemblies that have their own parts, across as many levels as you need. KnowBuild works out how many you can supply, and which part is holding you back.

Option 1 · Build ahead, sell from stock

For products you build before the order comes in. Record them as finished stock: sub-assemblies first, then the product. Every part used comes off stock, and the finished units go on.

Option 2 · Put it together as you ship

Option 2 · Put it together as you ship

For kits and bundles, keep only the parts in stock. KnowBuild shows how many kits you can sell from those parts. When the kit is dispatched, the warehouse scans each part and each one comes off stock.

What a bill of materials changes in your business

Eight ways KnowBuild grows your revenue and protects your margin

Each one is a problem we hear from distributors who sell kits and manufacturers who assemble. Select a problem to see what changes.

Before

A customer wants 10 kits. Can you supply them today? Someone has to walk into the store.

A kit or assembly needs many parts. Stock is checked part by part, by hand. One missing part holds up the whole order, and the customer hears about it on the delivery date.

KnowBuild · PQV · Bill of Materials

What changes

For every product with a bill of materials, your team sees how many you can supply today, worked out from the parts in stock, and which part is short. They see it before they quote, in the same line as price and discount.

Who uses the bill of materials

How you sell decides which option you use most

Choose per product

Built ahead and kits in one system

Many businesses do both: standard products built ahead, and kits or options put together as they ship. The win is one system that handles both.

  • Fulfilment method chosen for each product.
  • The same bill of materials for both.
  • One view of what you can supply today.
  • One dispatch process for everything.

Who this is for

Businesses with a standard range built ahead and kits or options put together at dispatch.

👍 Recommended for manufacturers

Run the whole business on one system

For makers who hold material, deliver to sites and give credit to institutions.

  • Inquiries, offers and follow-ups in one place
  • Products with their parts list, and how many you can make today
  • Alerts telling purchase what to buy, and when
  • Delivery orders, barcode checks before despatch, e-invoice and e-way bill
  • Payments due, reminders and credit limits

Sales OS: the Revenue Operating System

For firms whose biggest need is quoting, follow-ups and collections, and who want to keep Tally for now.

  • Every inquiry captured and given to the right salesperson
  • Quotes within discount limits, with follow-up reminders
  • Orders, dispatch instructions and payment tracking
  • Works alongside Tally, and moves up to QERP.CRM later

Sales OS revenue operating system turning opportunities into revenue

What's the difference? Sales OS runs your selling: inquiries, offers, follow-ups, orders and payments, working alongside Tally.

QERP.CRM is the full Business Operating System: everything in Sales OS, plus stock, purchase, dispatch, invoicing and finance, all connected. Start with either, and move up any time without losing data.

Most businesses with kits or assemblies begin with a 10 user starter pack on one workflow, usually inquiry-to-order or order-to-dispatch.

3X in 5 years
Built, not imagined

KnowBuild was born inside an Indian B2B business that grew 3X in five years. It has many products, imports and sells locally, and has money locked in stock, just like yours. That business still runs on KnowBuild today.

FAQ

Questions about the bill of materials

What are the two ways to fulfil a product?↓

Built ahead: you assemble the product before the order comes in and record it as finished stock through inventory conversion. Kit at dispatch: you keep only the parts in stock, and the kit is put together when it ships, with each part reduced at dispatch. You choose the method for each product when you set it up.

How many levels can a bill of materials have?↓

As many as you need. A product can contain sub-assemblies, which can contain their own sub-assemblies. Each sub-assembly is saved once and used wherever it is needed.

We sell medical and surgical kits to hospitals. Does that work?↓

Yes. Save each kit, such as a surgical dressing kit, a delivery kit or a first-aid kit, once with its items. KnowBuild shows how many complete kits you can supply from the items in stock, and which item is short. At dispatch, each item is scanned against the order and comes off stock.

Does KnowBuild schedule production on the shop floor?↓

No. KnowBuild does not handle work orders, routing, work-in-progress between stages, job cards, machine scheduling, or scrap and yield. It is built for products assembled from parts and sub-assemblies, not for staged production.

What happens to stock if an order is returned?↓

The same parts that went out go back into stock, even if the product's parts list has changed since. Stock in the system stays the same as stock on the shelf.

Do we have to stop using Tally?↓

No. Keep Tally for your final accounts. You can start with Sales OS next to Tally to fix inquiries, quotes, follow-ups and payments, and move stock, purchase and dispatch onto KnowBuild when you are ready.

How do we start?↓

With a 5-user pilot on the one area that hurts most, usually quote-to-order or order-to-delivery. You grow from there once it works.
