Key takeaways
- Vendor-neutral. Confirm specifics with any provider you evaluate.
- No rates, rankings or affiliate links.
Typical inputs
Company cash, observed spend, funding events, sometimes revenue. Personal credit scores are the traditional small-business input and are a different product family.
Why a limit can fall
If the limit is derived from cash, a lower balance can mean a lower ceiling. That can coincide with a fundraising delay — exactly when teams expect the card to “help”. Model cash, not authorised spend.
Questions to ask an issuer
- What inputs drive the limit?
- How often is it recalculated?
- Is it a hard authorisation cap?
- Can it decrease?
- Is any personal guarantee involved?
