What it means
In any organisation, giving everyone free access to company funds is a recipe for chaos. To manage cash flow and prevent fraud, businesses set up a structure of approval thresholds, known as authorisation limits.
These limits dictate how much financial commitment an individual can make on behalf of the company based on their role and seniority. For instance, a junior team member might only be able to approve purchases up to fifty pounds, while a department head can approve up to five thousand pounds.
Anything above that threshold requires sign-off from the finance director or the board. These limits usually apply to various types of spending, including purchasing orders, expense claims, invoice sign-offs, and company credit card usage.
They are typically embedded into accounting software and procurement systems, meaning the system automatically blocks transactions that exceed a user is designated threshold or routes them to the appropriate manager for review. Setting these boundaries matters because it balances operational speed with financial control.
If every single pencil purchase required the chief executive's signature, the business would grind to a halt. Conversely, if employees could spend whatever they liked, the company would quickly run out of money.
Authorisation limits ensure daily operations run smoothly while maintaining clear accountability for every pound spent. In practice, businesses review these limits regularly as people change roles, inflation alters costs, and the company grows.
They form a core part of internal financial controls, which auditors look closely at to ensure the business is well managed and protected against accidental overspending or deliberate misuse of funds.
In practice
Real-world examples.
Example
At our start-up, junior software engineers have a purchasing limit of 100 pounds for cloud tools, team leads can approve up to 1,000 pounds, and any software subscription above that requires co-founder sign-off.
Example
Our boutique marketing agency allows account managers to sign off client expenses up to 250 pounds. Costs between 250 and 1,500 pounds need the operations director's approval before booking.
Example
In our manufacturing firm, shift supervisors can order emergency replacement parts up to 500 pounds. Plant managers handle limits up to 5,000 pounds, while major machinery overhauls need board approval.
Think of it
“An authorisation limit is like a debit card daily spending limit. You can buy your daily coffee without calling the bank, but if you want to buy a car, your card will decline until a manager approves the larger amount.
Formula
Calculation
Authorisation Limit = Maximum Spend Approved for Employee Role (e.g., Team Leader = £1,000 per transaction). If Transaction Amount > Employee Limit, then Status = Pending Manager Review.Case study
Seen in the real world.
Bright Spark Design, a growing design agency with thirty staff, faced a cash flow crisis when employees freely bought software and office supplies on company cards without oversight. The founders implemented strict authorisation limits using their expense software. Junior designers were capped at fifty pounds per month for minor stock images. Project managers could approve client-related purchases up to five hundred pounds. Any equipment or software license exceeding that amount required the approval of the finance manager.
Within three months, unnecessary software subscriptions dropped by thirty percent, and the founders regained a clear view of monthly outgoings. When the creative director attempted to purchase a new five thousand pound rendering workstation without approval, the procurement system automatically flagged the transaction and routed it to the finance manager. The purchase was paused, reviewed against the current project budget, and properly budgeted for the following quarter. By enforcing these clear boundaries, Bright Spark Design protected its cash reserves and fostered a culture of financial responsibility across the team.
Watch out
Common mistakes.
- Setting authorisation limits too low, which creates unnecessary bottlenecks and slows down daily business operations.
- Failing to update limits when employees are promoted or when inflation makes older thresholds impractical.
- Allowing staff to share login credentials, which completely bypasses the security and tracking provided by individual limits.
Questions
People also ask.
What happens if I need to make a purchase that exceeds my limit?
You must submit a purchase request through your company system so it can be reviewed and approved by someone with a higher spending limit.
Are authorisation limits the same for everyone in the same job title?
Not necessarily. While roles often dictate limits, companies may adjust them based on individual experience, departmental needs, or specific project requirements.
Do these limits apply to company credit cards as well as invoices?
Yes. Most businesses tie company credit card transaction limits directly to the cardholder is approved authorisation threshold to prevent misuse.
