The document starts the request.
AI extracts invoice details and uses the conversation to build an editable draft.

Give the decision its context.
An approver reviews the request with supporting evidence and records the decision in its history.
04 / 04
Finance knows what comes next.
An approved request reaches the finance queue with its details, evidence, and approval history.
Illustrated product workflow. Fictional request and demonstration data.
THE CHALLENGE
A receipt is only
part of the request.
Someone needs to explain the expense. Someone needs to approve it. Finance needs the evidence and instructions to take it forward.
Vaster Expenses connects those responsibilities in one workspace. Vendor invoices, employee reimbursements, and company-card approvals each follow the appropriate request structure, with supporting documents and a visible history that carry through the handoff.
THE PRODUCT
AI handles the preparation.
People own the decisions.
The detail is in how a conversation becomes a usable request—and how that request reaches the right team.
The draft follows the discussion.
Ask to change an amount, correct a description, or remove an item. Targeted chat edits update the structured draft, while ambiguous instructions prompt a follow-up. The conversation and the request stay connected.
Keep the receipt with the cost.
Documents are associated with individual expense items using extracted references, vendors, and amounts. Transaction deduplication helps reconcile overlapping inputs, so reviewers can trace the supporting evidence.
The request fits the work.
Pay a vendor, reimburse an employee, or seek approval before a company-card purchase. Each uses a tailored draft, including vendor payment preferences, invoice references, and reimbursement context. Submission creates the request, its items, attachment links, and initial activity together.
Approval has a next step.
Approvers see pending requests. Finance sees approved requests that need follow-up. Notifications move the work between those roles and keep the requester informed, with comments alongside the request.
Corrections keep their context.
Authorized staff can correct a request’s workflow type and review every affected item. Decisions, comments, and notification delivery events create a history the team can return to as the request moves toward completion.
WHAT THIS ENABLES
Less reconstruction.
A clearer next action.
Vaster’s team can work from a shared request instead of piecing together an explanation, an attachment, and an approval.
The product brings preparation, evidence, review, and finance follow-up into a connected process. AI helps assemble and refine the information; permissions, explicit decisions, and recorded activity support the operational work around it.
