How to set up a purchase order system

Purchase order total
$827.21
Line total before discount
$740
Discount agreed
$37

Nothing in these worksheets is a figure we found somewhere. Every number comes from the inputs you enter and the method stated on the page: the discount comes off the line total before tax, tax is charged on the goods and not on shipping, and the budget check is your own remaining balance less your own estimate. The defaults are a worked example, not a recommendation and not a benchmark.

Setting up a purchase order system in a business that has never had one is mostly a sequencing problem. Businesses usually start by choosing software, which is the last step rather than the first, and the software then encodes a process nobody has agreed. The order that works is: decide who may commit spend and up to what, agree a numbering scheme, write the two documents, run it on paper or a spreadsheet for a month, and only then buy something to hold it. By that point you know what you actually need.

Decide the authority before the tooling

Who may commit the business, up to what value, and who is the second approver above that. This is a twenty-minute conversation and everything else depends on it. Software that arrives before this decision will make the decision for you, badly.

Pick a numbering scheme and never reuse a number

Sequential is fine and simple is better than clever. On the worked example the next number is 1042. The only rules that matter are that numbers are never reused and that the number appears on the document the supplier receives, so it comes back on the invoice.

Run it manually for a month before buying anything

A month of real requisitions and real orders will tell you what your threshold should be, which fields nobody fills in, and whether the bottleneck is approval or lead time. Buying software first means paying to learn the same things more slowly.

How to set up a purchase order system: common questions

How do I set up a purchase order system from scratch?

Decide who may commit spend and up to what, agree a numbering scheme, write a requisition form and a purchase order, run it manually for a month, then choose software to hold what you have proved you need.

What should a purchase order number look like?

Sequential, never reused, and printed on the document the supplier gets. Prefixes by year or department are optional and mostly cosmetic; what matters is uniqueness and that it comes back on the invoice.

How long does this take to introduce?

The decisions take an afternoon. The habit takes a month, and the thing that makes it stick is that invoices without a purchase order number get queried rather than paid.
