Hold one materials list per item, with versions, wastage and cost.

A bill of materials lists everything one finished item needs: each material, the quantity, the wastage you allow for, and the bought-out parts. Held in one place, it lets the quotation, the purchase list and the shop floor work from the same numbers. When the design changes next month, last month’s version stays on record.

What it is

The estimator keeps the list in a spreadsheet, with a column added for one customer years ago. The storekeeper has a different idea of what goes into the same item. When the drawing changes, one of the two finds out late.

One item has one list of what goes under it, carrying a version and a date. A quotation is costed from it, a purchase list is drawn from it, and a work order is released against it. Wastage sits on the line where it belongs, so the edge banding you always lose is priced and not absorbed.

What it replaces

What your team uses today.

The module takes over these, one at a time, so nothing has to stop while it is set up.

  • The estimator’s own spreadsheet of material lists
  • A notebook of cutting sizes and wastage
  • Phone calls to ask which fitting goes in
Where it goes wrong today

The problems this is meant to ease.

Material lists live in heads

The estimator knows what a wardrobe needs. When he is on leave, the quotation and the purchase list are built from guesswork.

Wastage is forgotten

Cutting loss and shrinkage are not on the sheet. Stock runs short midway through a batch, and the shortfall is blamed on the storekeeper. Waste is real, yet unwritten.

Design changes overwrite history

A new hinge replaces the old fitting in the same file. Nobody can say which version a past job was quoted from. History is lost with it.

Costs go stale

The sheet carries a rate from last season. The quotation looks fine until the purchase invoice arrives at a different figure.

Shortages stop the line

The usual part is off the rack and no alternate is written down. The supervisor phones around while the work waits.

Inside the module

What bill of materials does.

Parent items and what sits under them

A finished item, its materials, and sub-assemblies under those. The shutter panel sits inside the wardrobe that carries it.

Wastage on the line

An allowance for cutting loss, shrinkage or thread breakage, set per line and in the unit the trade uses.

Versions with a date

Each change is saved as a new version, dated and tagged with the user who saved it. Jobs already quoted keep the list they were quoted from.

Alternates for what is short

A second acceptable material against a line tells the supervisor which hinge may go in when the usual one is off the rack.

Costed at the last purchase rate

Each line picks up the latest purchase rate. The total says what the piece costs before labour.

Explode it for a quantity

Ask for forty units. The screen returns the whole material list, what is on the rack and what has to be bought.

Where it gets used

What this looks like in a working week.

Illustrative scenarios, written to show the shape of the work. They are not accounts of client systems.

Quoting a custom piece

An estimator picks the finished item and the quantity. The screen lists the materials with wastage and prices them at the latest purchase rate. Costing follows the list.

Planning a production batch

The production in-charge explodes a batch. On the screen sit what is on the rack and what has to be bought, and the purchase request is raised from that list.

A design revision mid-month

The designer saves a new version with a changed fitting. Jobs already quoted keep their old list, and new quotations pick up the revised list. Old jobs stay untouched.

A short-supply morning

The storekeeper finds a hinge missing. The line shows an alternate that is acceptable, and the supervisor switches without waiting for a call.

Who touches it

The people who open this every day.

Estimator

Builds the list once and quotes from it, instead of rebuilding it whenever the same customer asks for the same cabinet.

Production in-charge

Sees what a job needs before it is released to the floor.

Storekeeper

Issues against the list. Anything beyond it is asked for in writing.

How it is set up

From first conversation to daily use.

  1. Walk through your products

    You show a few finished items and describe how they are made. You get a written note on how the parent items and sub-assemblies will be laid out. Begin with a few products.

  2. Load the materials and units

    You supply item names, units and wastage habits from your sheets. A trial import comes back for you to correct before anything is relied on. Corrections come cheaply here.

  3. Check costs against purchases

    Recent purchase rates are connected to the lines. A costed list for a few products is laid beside your own working for comparison.

  4. Try the explode screen

    The estimator and the storekeeper explode a batch on the trial. You hear what is missing, and the layout is changed. Gaps surface early.

  5. Move quotations onto it

    New quotations start from the list. The team is shown how to save a version and how to mark alternates.

Measuring it

How you would know it is working.

Record where you stand before it goes live, so the change is measured against your own figures.

  • Quotations raised from a saved list against those typed by hand
  • Material shortfalls found at the line, by item
  • Wastage allowed against wastage seen, by material
  • Orders where cost differed from the quoted material cost
  • Items with a current version and an owner
How it fits

It is one part of a system, not an island.

A module earns its place by what it passes to the next one. These are the connections we set up most often.

  • Production planning
  • Work orders
  • Purchase orders
  • Stock
  • Estimates and quotations
Common questions

Questions owners ask about bill of materials.

Every job we make is a one-off. Is this useful?

Yes, in a lighter form. A fabricator keeps a list for a standard gate or a rolling shutter and changes the sizes per job. The gain comes from costing each job against that list afterwards.

Is a spreadsheet still enough for us?

Often it is. It stops being enough the day two people keep copies, or rates move and old quotations go out at last year’s cost. A store that issues from memory is the third sign.

Can it read rates from our accounting software?

Yes, purchase rates and item masters come across from your accounting software, so the costed list uses what you actually paid. Nothing is keyed twice. Books stay with your accountant.

Can our existing lists be loaded in?

Send the sheets in whatever shape they are in. They are cleaned and imported before go-live. Costing errors tend to hide in these sheets, so they are the first thing we look at.

What makes a bill of materials cost more or less?

The count of finished items and the depth of their sub-assemblies set much of the effort. Connections to stock, purchase and quotations add to it, as do the users involved. The quotation is itemised once the scope is read, and a part can be left out. Scope sets the figure.

What decides how long setup takes?

The state of your material lists decides it. A release holding a few products with costs can come early, and the rest follow. Item names, units and wastage come from you, and the proposal fixes the order of work along with its dates.
