Bookkeeping and BASReconciles, prepares BAS and workpapers, and chases what's missing. Lodges nothing.
Ninjafy for accounting firms
Every firm can buy the same AI. Yours should know your clients, work your way, and stay yours.
The shift
Growth has meant hiring faster than good accountants can be found. Teammates give every person in the firm more capacity.
Whatever you subscribe to, the firm down the road can have tomorrow.
How you review, advise and price, captured once, improving with every client.
Nothing to migrate. Teammates log in where your people already work, with the access you give them.
Two kinds of firm
One rents tools and gets busier. The other owns teammates that learn the firm and get better every quarter. The difference shows up first in BAS month, then on the P&L, then on the sale price.
Client context dies with the tab. Every BAS starts from nothing, so nothing gets better.
Nobody can say who pasted what. Client data in personal accounts, with no list, no owner and no audit trail.
The hour stays the ceiling. More tools, the same billable hours, the same burnout every BAS month.
The method walks out the door. When a senior leaves, how your firm does things leaves with them.
Illustrative · the typical pile
Every BAS cycle they run adds approved lessons, sharper routines and cleaner files.
Rented tools reset every session. An owned team keeps every lesson your partners approve.
Owned routines, client knowledge and an audit trail are assets. A pile of subscriptions is not.
Meet the crew
Each one reports to someone in your firm, works in the tools you already use and is measured on one number. Start with one.
Reconciles, prepares BAS and workpapers, and chases what's missing. Lodges nothing.
New client in: engagement letter, ID checks, prior-year files and Xero access, without a partner chasing.
Every meeting prepped, every follow-up sent the same day, every promise to a client tracked.
Answers routine questions from the file, and spots clients who need an advisory conversation.

How we start
No three-month program dropped on you in BAS season. One teammate, one job, timed for your quieter weeks, and nothing reaches a client until a partner says so.
We sit with the people who do it today, write down how your firm does it, and set the one number it will be measured on.
The teammate works read-only on a set of clients you choose. Your team reviews every output against what they would have done.
Live on that job with partner sign-off in place. Add the next teammate when your calendar allows, and pause over your peaks.
While it is being built
Yours to keep
Your context, your methods and your teammates accumulate quarter after quarter, and every bit of it belongs to the firm. It is the part of your AI a buyer's diligence will actually value.
Every file note, preference and history, in one place your whole team can use.
How you review, advise and price, written once as skills every teammate follows.
BAS quarter, EOFY and onboarding, run the same way every time.
Every action and approval, ready for a partner, a reviewer or a buyer.
Any model, swapped as better ones arrive. Export everything, any time. If you leave, it leaves with you.
Then take it to your clients
Once your teammates are running your firm, the same crew can run your clients' bookkeeping, payables and reporting, as a new service under your name.
Founding firms
Founding firms work directly with our founders and engineers, decide which accounting skills we build first, and keep everything their teammates learn.
