Many finance teams use the terms “expense limits” and “spend controls” interchangeably, but they’re different. Expense limits cap how much an employee or team can spend in a given period, while spend controls are specific rules on where and how money can be spent, regardless of the amount. Mixing these up, or assuming one covers the other, is a common gap in corporate card policy.
In this article, you’ll learn more about what each term means, why a strong corporate card system needs both, and how to quickly set up cards, limits and controls in Mamo.
An expense limit is a fixed cap on how much an employee or team can spend in a given period. For example, AED 2,000 per month per cardholder, or AED 500 per transaction.
Limits can be set at different intervals: per transaction, daily, or monthly, depending on how closely your business needs to manage corporate spending.
An expense limit answers one question: How much can I spend?
It’s not about what the money is spent on, only how much of it can move through the card before it’s declined.
Spend controls are rules that govern where and how money can be spent, regardless of the amount.
This includes:
Spend controls answer a different question than expense limits: Where and how can I spend?
A card with spend controls, but no spending limit can still only be used the way it’s intended to be used.
Expense limits prevent going over budget. Spend controls prevent policy violations. Each one closes a gap the other can’t.
A card with an AED 5,000 monthly limit and no category controls can still be used for non-business purchases. The limit alone won’t stop that, since staying under AED 5,000 doesn’t mean the spend was for business purposes. Someone could use the full amount for a personal purchase, and the limit itself has no way to flag that as a problem.
A card with strict category controls but no limit runs the opposite risk. It could technically overspend within an approved category, since the control is only specific to where the money goes, not how much.
For example, a travel card restricted to airlines and hotels is still following policy at AED 500 or AED 50,000, if there’s no cap attached.
Used together, expense limits and spend controls close both gaps at once: One governs the amount, the other the purpose. A policy built on both is far harder to sidestep than one relying on just one.
AED 10,000 per month limit (expense limit), restricted to advertising platforms only (spend control).
This means the team can spend on ad campaigns, but the card is functionally useless anywhere outside that category.
AED 2,000 per month limit, restricted to hardware stores and approved suppliers.
A smaller limit reflects a more narrow and predictable spend pattern, paired with controls that keep purchases tied to specific, pre-approved vendors.
AED 15,000 limit, restricted to airlines, hotels and transport merchants. The higher limit accounts for the cost of travel itself, while the category controls keep spend confined to travel-related purchases only.
Each example pairs a specific amount with a specific purpose, so the card can only be used the way it’s meant to be used and for the amount it’s meant to cover.
Mamo lets businesses issue unlimited cards, each with its own per-card spend limit and category controls to restrict or allow specific merchant category groups.
As of July 2026, Mamo also supports global spend controls, which is a company-wide policy set once, with the ability to override it for specific teams or users.
Using global spend controls, your business could set a default of AED 5,000 per month across the company, while senior managers are set to AED 12,000. Instead of configuring each card individually, your finance team can set the baseline policy once and manage exceptions from the same place.
Setting up both takes just 3 steps:
Mamo is also regulated by the DFSA, so the infrastructure behind every card and every policy meets the same standard UAE financial regulators require.
Yes. A card can have a spend limit with no category or merchant restrictions, but this leaves the card open to any type of purchase within that limit, which most businesses would want to avoid.
Yes, though it's uncommon. A card can be restricted to specific categories or merchants with no cap on amount, but this means spend within that category is technically unlimited.
Yes. Both apply the same way to virtual and physical cards, so a virtual card issued for a single vendor or subscription can carry the same limit and category restrictions as a physical one.
Yes. Both can be adjusted at any time from the Mamo Dashboard, without needing to reissue the card.
Expense limits and spend controls solve different problems. Mamo lets you issue unlimited cards for free, set expense limits and spend controls on each one, and apply a global spend control policy across the whole company.
