Decline Buffers
Note: Decline buffer settings are visible to Admins only. Employees see only the base fund limit — not the buffer percentage or amount.
Overview
When a card transaction slightly exceeds a fund's spending limit, it normally gets declined — even if the overage is just a few dollars. Decline buffers add a configurable percentage-based cushion on top of your fund limits, so small, low-risk overages are approved instead of blocked.
Decline buffers are opt-in and configured by Admins.
How decline buffers work
A decline buffer can approve a purchase that takes a fund over its base spending limit by up to the effective buffer. Ramp applies the buffer only when the fund's spend before the purchase is at or below the base limit and the purchase keeps total spend within the base limit plus the effective buffer. The employee still sees their original limit — the buffer works behind the scenes.
Example: A weekly fund has a USD 100 base limit with a 10% buffer. If its current spend is USD 99, a USD 6 purchase can be approved, bringing spend to USD 105. Another purchase is declined while spend remains above the USD 100 base limit, even if it would keep total spend below USD 110.
- Percentage-based: The buffer is set as a percentage (0–100%) of the fund's limit. The default suggested buffer is 10%.
- A one-time save, not a cumulative spending allowance: Once a purchase takes spend above the base limit, any nominal buffer remaining does not approve another purchase. Ramp checks the fund's current spend before each purchase rather than tracking a permanently consumed portion of the buffer. To allow additional spending while the fund is over its base limit, an Admin must increase the base limit. Increasing only the buffer does not unblock the fund.
- Max buffer amount (dollar cap): A dollar cap can be set at the business level to limit the buffer on high-limit funds. Ramp uses the lesser of the buffer percentage amount and the dollar cap. If no custom cap is configured, the default cap is $10,000.
- Precedence: Fund > Spend Program > business-wide. The most specific setting wins. Setting a buffer to 0% at any level explicitly disables the buffer and prevents fallback to a higher-level default; leaving it unset lets the fund inherit the next level up.
- Card transactions only: Decline buffers apply to card transactions (physical and virtual). They do not apply to reimbursements.
- Shared funds: Decline buffers apply to shared funds. On a shared fund, overage amounts are hidden from members but visible to the fund's owner and co-owners.
- Invisible to employees: Employees see only the base fund limit. They do not see the buffer or any indication that one is active.
For Admins
You can configure decline buffers at three levels: business-wide, per Spend Program, or per individual fund. When more than one level is set, the most specific one applies (fund > Spend Program > business-wide).
Set up a business-wide decline buffer
A business-wide setting applies a default buffer to funds across your business.
- Go to Policy > Travel & expenses. Depending on your business's settings experience, decline buffers appear as a separate Decline buffers entry or in the Decline buffers section within Expense requirements.
- In the Decline buffers section, choose Set an amount and enter the default buffer percentage.
- Optionally, set a Max amount (dollar cap) to limit the buffer on high-limit funds.
- Choose whether the buffer applies to all funds or only to funds created going forward. Existing funds are unaffected when you apply it only to new funds.
- Save your changes.
Set up a Spend Program decline buffer
A buffer set on a Spend Program applies to all funds issued through that program, overriding the business-wide default.
- Go to your Spend Programs page and open a program, or create a new one.
- In the program's Advanced settings, find the Decline buffer (%) control.
- Choose Custom amount and enter a percentage, or keep the business default.
- Save the program.
Set up a fund-level decline buffer
A fund-level buffer applies to a single fund, overriding both program-level and business-wide settings.
- Go to Cards and open a fund, or create a new one.
- In the fund's Advanced settings, find the Decline buffer (%) control.
- Choose Custom amount and enter a percentage, or select None to disable the buffer for this fund.
- Save the fund.
Keep the business default to inherit the buffer from the Spend Program or business-wide setting.
Edit a decline buffer
To change an existing buffer, return to where it was configured:
- Business-wide: your decline buffer settings.
- Spend Program: the Advanced settings of the Spend Program.
- Fund: the Advanced settings of the fund.
Monitor overages
When decline buffers are enabled, overage amounts appear in your funds view, so you can see where buffers are being used and whether limits need adjusting. The Spend Programs table shows an Allowed buffer column with the effective buffer percentage for each program.
For Employees
What you see
Your fund limits appear as normal — the base limit your Admin set. You will not see any indication that a decline buffer is active on your fund.
If a transaction goes through that would normally have been declined — because it exceeded your base limit but fell within the buffer — Ramp shows a message that your finance team let it through this time.
If a transaction is still declined
Even with a buffer, a transaction is declined if the fund's spend is already above the base limit before the purchase or if the purchase would take total spend above the base limit plus the effective buffer. If this happens:
- Check your remaining fund balance in the Ramp app.
- If the fund is already over its base limit, request an Admin-approved base-limit increase. Increasing only the buffer does not unblock an already-over-base fund.
- If the fund is at or below its base limit but the purchase would take total spend above the base limit plus the effective buffer, ask your Admin to increase the base limit or buffer. See Spend requests and spending limit increases.
Frequently asked questions
Can employees see decline buffers on their funds?
No. Employees see only the base fund limit. The buffer percentage and amount are visible only to Admins.
How does the max buffer amount (dollar cap) work?
The dollar cap is set at the business level and acts as a ceiling. Ramp uses the lesser of the buffer percentage amount and the dollar cap. For example, if a fund has a $10,000 limit with a 10% buffer ($1,000) but the dollar cap is $200, the effective buffer is $200. If no custom cap is configured, the default cap is $10,000.
Can I set different buffers for different funds?
Yes. You can set a business-wide default and override it on individual Spend Programs or funds. You can also leave the business-wide setting off and configure buffers selectively on specific programs or funds.
Do decline buffers apply to shared funds?
Yes. On a shared fund, the buffer still applies. Overage amounts are hidden from members but visible to the fund's owner and co-owners.
Do decline buffers apply to all transaction types?
Decline buffers apply to card transactions (physical and virtual). They do not apply to reimbursements.
What does setting a buffer to 0% do?
Setting a buffer to 0% at any level explicitly disables the buffer and prevents fallback to a higher-level default. This differs from leaving the buffer unset, which lets the fund inherit the buffer from the Spend Program or business-wide setting.
What happens when a fund's limit resets?
Ramp recalculates the buffer from the new base limit, and current spend starts again for the new spend period. Ramp can apply the recalculated buffer only when spend before a purchase is at or below the base limit. The buffer does not carry over from the prior period.
