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 $50, while a department head can approve up to $5,000.
Anything above that threshold requires sign-off from the finance director or the board. These limits usually apply to purchase orders, expense claims, invoice sign-offs and company credit card usage.
They are typically built into accounting software and procurement systems, so the system automatically blocks transactions that exceed a user's 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 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 dollar 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 confirm the business is well managed and protected against accidental overspending or deliberate misuse of funds. 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.
In practice
Real-world examples
Example 1
At a start-up, junior software engineers have a purchasing limit of $100 for cloud tools, team leads can approve up to $1,000, and any software subscription above that requires co-founder sign-off. This keeps small experiments quick while the founders still see every large commitment. The finance lead reviews a monthly report of anything approved near a limit.
Example 2
A boutique marketing agency allows account managers to sign off client expenses up to $250. Costs between $250 and $1,500 need the operations director's approval before they are booked. Because the thresholds are written into the expense system, nobody has to remember the policy or chase approvals by email.
Example 3
In a manufacturing firm, shift supervisors can order emergency replacement parts up to $500. Plant managers handle limits up to $5,000, while major machinery overhauls need board approval. When a production line stops at night, the supervisor can act at once, yet large capital spending always gets proper scrutiny.
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
Rule: if Transaction Amount > Employee Authorisation Limit, then Status = Pending Manager Review; otherwise Status = Approved.
Worked example: a team leader has a limit of $1,000 per transaction. A $750 software renewal is below the limit, so it is approved immediately. A $4,200 laptop order is above the limit by $4,200 - $1,000 = $3,200, so the system routes it to the department head, whose limit is $5,000, and it is approved there.
A related check is the split-purchase test. If the same team leader raises four separate $900 orders to one supplier on the same day, the combined total is 4 x $900 = $3,600, which is well over the $1,000 limit. Good controls add up related purchases so the limit cannot be dodged by splitting a bill.Case study
Seen in the real world
This is a fictional, illustrative scenario. 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 $50 per month for minor stock images.
Project managers could approve client-related purchases up to $500. Any equipment or software licence above that amount required the approval of the finance manager. Within three months, unnecessary software subscriptions dropped by 30%, and the founders regained a clear view of monthly outgoings. When the creative director attempted to purchase a new $5,000 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 planned for the following quarter. The founders also reviewed the limits each January, raising them where the original figures had started to slow down legitimate work. 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's approved authorisation threshold to prevent misuse.
