Order to invoice: eight steps in a make-to-order shop
The eight steps between a customer's order and the invoice in a make-to-order workshop, where the chain usually breaks, and what the retyping costs.
A customer chooses a size, a material and a door. Some weeks later a lorry leaves the yard.
Between those two moments there are eight steps. In most small manufacturing companies at least three of them are done by hand — twice.
What follows is not a list of what software could do. It is the chain as it actually runs in one manufacturer, written down after building it.
1 · The order arrives
A configurator, a form, an e-mail, a phone call. The door does not matter. What matters is that this is the only moment when the customer says exactly what they want, in their own words — and almost everything that goes wrong later begins with that being written down loosely.
2 · The order becomes a record
A number, a customer, a date, a list of lines.
Here a small manufacturer loses the first hour. The order is sitting in an inbox, so somebody types it into a spreadsheet to make it exist somewhere countable. That is retyping number one.
3 · The money is agreed
A quote, a deposit, an invoice on account.
And here belongs a rule nobody thinks about until it hurts: what an order number actually means. Issue it before the money is agreed and the numbering starts carrying cancelled orders. The accountant's sequence ends up with holes in it, and she will ask about every single one.
4 · The order becomes work
Somebody on the floor needs to know what to build, in what material, with which fittings.
In a make-to-order shop the production sheet is not a copy of the order. It is a translation of it — and translating by hand, from a screen onto a printed sheet, is retyping number two.
5 · Materials are taken
Sheets, timber, fittings, a heater. Stock goes down.
In most workshops this is either not recorded at all, or recorded a week later from memory. Those two are the same thing.
6 · It is finished, and it leaves
A delivery note, a consignment note, a photograph, a signature.
Different customers and different countries want different paper here. All of that paper wants the same facts that were typed in at step one.
7 · The invoice is issued
Same customer, same lines, same amounts, same VAT — typed a third time, now into the accounting program, because that is where the accountant looks.
8 · The month closes
What was sold, what was made, what is left on the shelf, and the figure the state asks for.
Three times, by hand, from the same words
Count the retyping: step two, step four, step seven. Each one takes minutes. Each one can put a wrong number somewhere nobody will look until a parcel is already on a lorry, or until an invoice is in front of an accountant.
Where the chain actually breaks
Not at the front, and not at the end.
It breaks between four and seven — between the order and the invoice, where the work happens and where nothing holds the two together. A shop can have a good configurator at the front and a good accounting program at the back, and still have one person in the middle keeping them in agreement by hand.
The fix is not a bigger program
It is that the order, the production sheet, the stock movement and the invoice stop being four documents that happen to agree because somebody checked, and become one record seen from four sides.
That is what an operating system for a manufacturing company means in practice. It is also why "we already have an ERP" and "we do not need an ERP" are usually both beside the point: a full enterprise system is too much for a fifteen-person workshop, spreadsheets plus an accounting program are too little, and what is missing in between is one chain from the first click to the consignment note, built around how that shop already works.
One question, and it is not which software to buy
How many times does a single order get typed in your works, and by whom?
Count it this week. If the answer is more than once, write and tell us where the hours go — we will say honestly whether it is worth building.
