Bank & Ledger Verification — Single or Multi-Entity
We go line by line and make sure what's in your bank account matches what's in your bookkeeping — no more guessing which number is right. We track money moving between one or more accounts and entities.

Knowing Where Your Money Goes
Cash Flow Check-Up
We show you when money actually lands in your account — not just when you sent the invoice — so you're never caught short.
Real cash timing
Vendor & Subcontractor Bill Review
We check what vendors and subs are actually charging against what you agreed to pay, and flag anything that doesn't match.

Matching Payments to Your Invoices
We match every payment you receive back to the invoice or contract it belongs to, so you know exactly who paid, who didn't, and who's short.

Progress Billing & Retainage Check
For draws and milestone payments, we verify what you billed matches what was approved and received — including retainage held back until the job closes.

Written Procedures, So Nothing Depends on One Person
Custom SOP Playbook
A step-by-step playbook built around how your office actually works — from taking in a vendor bill to closing out the month — spelling out who does each step, who checks it, and who signs off. If your bookkeeper leaves or you bring on new office help, the process doesn't leave with them.

Our Story
The person behind every number.
Lana TselishchevFounder & Accountant
Throughout my career, I repeatedly watched businesses run into the exact same wall: assuming that because transactions are being recorded, the numbers must be right. When something breaks between daily logging and year-end filing, it falls into an operational void. Everyday transactions continue to pile up on top of unreconciled discrepancies—masking timing errors, missing payouts, or broken data feeds. XI:XI was built to close that gap. I bring structured, statement-to-ledger precision directly to your business operations, giving you clear, plain-number visibility into exactly where your ledgers and bank accounts diverge—and resolving those discrepancies before they turn into a bigger issue.
