Minimum necessary access
External collaborators receive the narrowest credential that supports the work, rather than a general purpose card.

Purpose-Scoped Cards for Contractors and Remote Teams
Contractors and distributed teams need to buy software, equipment, and project inputs without holding broad access to company funds. Mainsail Cards supports workflows that issue narrow, purpose-scoped credentials tied to a project and engagement period, with documentation requirements and automatic closure when the engagement ends.

Target customers
Who this is for
- Companies working with contractors, freelancers, and agencies
- Distributed and remote-first teams across multiple regions
- Project-based organizations with defined budgets per deliverable
- Teams onboarding temporary staff for a fixed period
Why a card program
The operational problem
- Contractors pay out of pocket and invoice later, which delays visibility and complicates tax documentation.
- Giving a contractor a standard employee card grants more access than the engagement requires.
- Project spend is not attributable to a deliverable or budget line.
- Access often outlives the contract.

- 1
Engagement and budget definition
The project, deliverable, budget, and engagement dates are recorded with an internal sponsor who approves spend.
- 2
Scoped card issuance
Subject to partner approval, a virtual card is issued for the specific purpose, with a limit matched to the budget and expiry matched to the engagement end date.
- 3
Documented spend
Each purchase requires a receipt and a note linking it to the deliverable before the next purchase is approved.
- 4
Sponsor review
The internal sponsor reviews spend against the budget and confirms that purchases match the agreed scope.
- 5
Engagement close
The card closes on the engagement end date, and remaining budget is released back to the project.

Risk and compliance
Controls that keep this scenario reviewable
Sponsor accountability
Every contractor card has a named internal sponsor who is accountable for the budget and the review of spend.
Automatic expiry
Contract dates drive card validity, so access ends with the engagement without relying on a manual cleanup step.
Monitoring signals
- Spend against engagement budget by project
- Purchases outside the agreed merchant categories
- Cards active past a contract end date
- Missing receipt aging by contractor
- Repeat limit increase requests within one engagement
Integration touchpoints
- Project and engagement records linked to card metadata
- Sponsor approval workflow for issuance and increases
- Webhook events for authorization, expiry, and closure
- Project cost reporting by deliverable
Partner review
Notes for program partners
- Purpose-scoped, non-renewing credentials keep external access narrow and time-bounded.
- A named internal sponsor for each external card preserves accountability inside the business entity.
