What makes expense management AI-native?
AI-native expense management proposes the coding itself instead of matching a card transaction against rules someone has to maintain. Vergo reads the receipt behind each BQE Core card charge line by line and infers the coding from what was actually bought and from how your team has coded similar spend in BQE Core before. A rules engine has no pattern for a supplier nobody has set up, so it queues the charge for a person; Vergo codes it on first sight and shows the reason, so review in BQE Core is a confirmation rather than a re-coding.
How does Vergo work with BQE Core?
Vergo connects directly through the public BQE Core API with OAuth 2.0 — self-serve, with nothing needed from your team or from BQE — and reads your accounts, projects, expense items and vendors. Confirmed card spend posts into BQE Core as expense entries — in batches when there are many — against the right project, expense item and account, with the billable flag set the way your team would set it. New accounts and projects appear in Vergo as they are created in BQE Core, so nobody codes against a stale list. The full specification lives on the BQE Core integration page.
What does BQE Core need on each card transaction?
- Project: the project the expense is entered against.
- Expense item and expense account: what was bought and where it posts.
- Billable: whether the cost goes on the client invoice.
- Resource: the employee who made the purchase.
What does this look like day to day?
A civil engineer buys survey stakes and a replacement GPS battery on the firm card during field work. Vergo texts for the receipt, reads both lines, proposes the field supplies expense item on the client project for the stakes and equipment maintenance on overhead for the battery, and marks the stakes billable. The accountant confirms, and two expense entries land in Core.
Do we have to change cards to use Vergo with BQE Core?
No. Many platforms in this category issue their own card and earn on the interchange, so switching cards becomes the price of the software. Vergo does not issue cards: it connects the corporate cards, fuel cards and purchasing cards your business already holds and codes that spend for BQE Core. Connecting your existing cards involves no card applications, no re-issuing and no banking change, so the issuer, the credit line and the rewards stay exactly where they are.
What changes at month end in BQE Core?
The work moves from the end of the month to the moment of spend. Because coding happens when the receipt or invoice arrives, close in BQE Core becomes a review of exceptions rather than a pile of card statements. Card spend, employee reimbursements and AP invoices run through one coding model — same coding, same review, one reconciliation against the BQE Core structure — and payment stays on the rails you already use.

Who runs BQE Core?
BQE Core is cloud practice-management and project-accounting software built for architecture, engineering and consulting firms. Expense entries in Core are recorded against a project and an expense item, and they carry flags for whether the cost is billable to the client and reimbursable to the employee. If your finance team lives in BQE Core, the expense management layer should adapt to it, not the other way round.
Does Vergo do expense management for BQE Core?
Yes. Vergo codes company card spend against the structure it reads from BQE Core and delivers it to BQE Core coded and reconciled against a receipt.
