Bookkeeping & Accounting

Your books, closed
by day five. Every month.

A complete accounting function without a single full-time hire — reconciled, audit- and CPA-review-ready, with commentary that tells you what actually changed and why.

What we do

Not hours of data entry.
A finished monthly close.

Who we serve

Books that speak
your industry's language.

Generic bookkeeping produces generic reports. Every vertical has its own rules, its own traps and its own definition of a clean set of books.

Nonprofits

Fund accounting, restricted vs. unrestricted tracking, grant compliance, functional expense allocation, and books kept Form 990-ready all year.

Medical & dental

Books that reconcile to the remittance, not just the deposit. Payer-level revenue, provider profitability, and a team fluent in healthcare finance.

E-commerce

Multi-channel sales and payout reconciliation, COGS and inventory, platform fees and chargebacks, sales-tax nexus visibility.

Professional services

Project and client-level profitability, WIP and unbilled revenue, retainers and deferred revenue, utilization reporting.

Also serving pharmacies · restaurants & takeaways · retail & hospitality · trades & construction · real estate and property management · multi-location operators

What counts as a transaction?

Each line in your bank and card feeds for the month. Easy to count, nothing to argue about. If you grow past your tier's limits two months running, we move you up with 30 days' notice — never a surprise charge.

What “Day 5” means

Your close is delivered by the 5th business day after month-end, on every tier, once bank access is live and your documents are in by Day 2. We categorize through the month, so month-end is review, not catch-up.

Why limits at all?

So a fixed fee can stay fixed. Every client gets the same senior review and on-time close, because every engagement is sized to the work it actually takes.
