I Will Clean Up, Reconcile and Categorise Your QuickBooks or Xero Books

If your accounts are full of uncategorised transactions, duplicate entries, unmatched transfers, unreconciled bank accounts or lingering errors in your AP and AR, you already know the anxiety that comes with opening your books. Poor financial records don't just cause stress — they lead to bad decisions, missed tax deadlines and sleepless nights before an accountant review.

Zinn Digital is a London-based bookkeeping team that specialises entirely in QuickBooks Online and Xero cleanup, catch-up and reconciliation. With 150+ cleanup projects successfully delivered, and direct experience working alongside CPAs, we know exactly what clean, audit-ready books look like — and how to get yours there.

What you receive with every order:

Full transaction categorisation across your chosen accounts, bank reconciliation to ensure every account matches its statement, systematic error identification covering duplicates, mispostings, undeposited funds, credit card payment issues and unmatched inter-bank transfers, and a clear summary report so you can see precisely what was found and fixed.

How it works:

Once you place your order, we begin with a focused review of your file — we can typically identify the major issues within the first ten minutes. We then work through categorisation and reconciliation methodically, flag any questions via order chat, and deliver your corrected books alongside a written summary. Higher tiers include one or two consultation sessions so we can walk you through the findings and answer your questions directly.

Who this is for:

This service is built for small business owners, sole traders, startup founders and finance managers who use QuickBooks Online or Xero and need their books brought up to date, corrected or set up properly. It is equally useful ahead of a CPA or accountant review, a tax filing deadline, or a business funding application.

Why Zinn Digital:

We are QuickBooks and Xero certified. We are based in London and communicate in plain English. We focus on solving your problem, not upselling you on things you do not need. Every engagement is handled with full confidentiality. Fast turnaround, accurate output and reliable delivery are the three things our clients consistently highlight — and they are the three things we protect above everything else.

If your books are holding your business back, let's fix them properly — once and for all.
