Nobody plans to end up with a broken purchasing process. What actually happens is someone buys a tool on the company card without telling anyone, another person fires off a Slack message to their manager that says “can we get this approved?”, and then finance tries to log all of it in a spreadsheet that’s already three tabs deep and hasn’t been updated in two months.
Come board meeting time, the finance lead will spend days trying to reconstruct what the company spent on software last quarter, because half of those purchases were never properly recorded in the first place, and nobody can remember who signed off on what. Here’s what a proper purchase request lifecycle should look like at every stage, and where most businesses quietly get it wrong.
How a Request Should Start
Every purchase request needs to begin in one place, in one format. Doesn’t matter who’s making it. A marketing manager might email over a PDF quote while an engineering lead drops a link in Slack with zero context, and both of those are technically purchase requests, but neither one gives finance enough information to actually make a call on whether the spend makes sense.
Good submissions will capture the basics upfront: what’s being purchased, why, how much it’ll cost, and which budget it should come from. Most companies that outgrow the Slack-and-spreadsheet phase will move to intake management software that collects every request in a consistent format and sends it to the right approver based on things like value, department, category, or vendor type. Without that kind of routing in place, requests just sit in someone’s inbox until they eventually remember to check.
What the Review Stage Should Cover
Once a request reaches the right person, the review can’t just be a quick thumbs up or thumbs down. There are real questions that need answering. Does this purchase fit within the department’s budget? Does it duplicate something the company already pays for? Is there an existing vendor contract that covers this need, and does the amount require a second sign-off?
All of those checks take seconds if the information is easy to access. But when someone has to dig through old invoices or chase down answers across Slack channels, it’ll drag on for days. Companies that get this right will have clear approval thresholds written down somewhere everyone can find them, and they’ll actually follow those thresholds consistently instead of treating them as loose guidelines.
Why Tracking Matters After Approval
This is where most companies fall apart. They’ll nail the submission step, get approvals running properly, and then completely lose track of the request after that point. Nobody records when it was approved. The final cost doesn’t get logged anywhere. Three months down the line, someone spots a recurring charge on the company card and can’t figure out who authorised it or why.
A solid process will track every request from the moment it’s submitted all the way through to vendor payment, logging who approved it, when, and under what terms. That data living in one central place means preparing for a board meeting or an audit won’t turn into a week-long scramble. It becomes a five-minute report instead.
Build the Process Before You Need It
If your company is still small enough that the current setup works, that’s actually the ideal time to fix it. Getting a proper purchase request process in place with 20 employees will take a fraction of the effort compared to doing it at 200, when you’ve got three years of disorganised records to untangle on top of everything else.
Start with the basics: a standard submission form, a clear set of approval thresholds, defined routing for each type of spend, and one central place where every request gets logged.
Companies that treat purchasing as an afterthought tend to be the ones panicking before every board meeting and scrambling through every audit. The ones that build structure early will have a much clearer picture of where their money goes, and that visibility makes every future spending decision sharper.
