YOUR INFORMATION

You choose what you share

Before any data sale

We agree what records may be included and how they may be used. Information you are not entitled to share must stay out. Removing names does not cancel confidentiality agreements or make every record safe to sell.

When you ask for an assessment

NextLevel Data Broker uses your company name, email and the business details you enter to review your enquiry and contact you about an assessment. Requests are stored securely on our server. They are not published on the website, and submitting does not sign you up for marketing.

Do not enter customer identities, bank details, passwords or confidential business information. This form does not ask you to upload files.

Website tools

This website uses no advertising trackers or marketing cookies. Fonts are served from our own server. The animation can be paused and respects your reduced-motion setting.

When the team contacts you, you can ask about your enquiry, corrections or deletion by replying to them. Continuing use of records already sold is governed by the separate data agreement. Full website privacy notice

Accounting practices & finance teams

Getting the numbers right leaves a valuable trail

Every day your team matches invoices, finds mistakes and corrects figures. Records of how a wrong number was found and fixed show careful finance work in a way no textbook does.

See what you can share

No files to upload. No commitment to sell.

First sale of your records $50k–$500k
Then, from new records each year $25k–$250k and growing
Preliminary valuation within one week

Typical ranges, not a promise. The real amount depends on your records and the contract.

What you can share

Your checks and corrections are useful records

Years of queries, fixes and approvals, with client names, bank details and tax numbers taken out.

  • Reconciliations & corrections

    Bank and books that disagreed, the search for the cause, the correcting entry and the note on why

    • Xero
    • 1C
    • Bank statement exports

  • Invoice checks

    Invoices that did not match an order, carried the wrong tax or arrived twice, and the supplier's reply

    • Dext
    • M.E.Doc
    • Email

  • Approvals & expenses

    Expense claims sent back for receipts and journals approved after a second look

    • QuickBooks
    • Expensify
    • Outlook

  • Month-end close

    Checklists, odd figures questioned and what changed before the month was closed

    • BAS
    • Sage
    • Excel

  • Reports & review comments

    Draft reports, the reviewer's questions and the version that was signed off

    • Excel
    • Google Sheets
    • OneDrive

  • Supplier & client questions

    Missing papers chased, odd items queried and the replies that settled them

    • Email
    • Viber
    • Telegram

Your corrections are the valuable part

A mismatch, followed until it was put right

Finished accounts are everywhere. The trail of how a wrong number was found and fixed is rare, and it is exactly what buyers want.

  1. Mismatch found Bank and books disagree
  2. Query Supplier or colleague asked
  3. Correction Entry fixed, reason noted
  4. Before and after kept Old figure beside the new one
  5. Signed off Manager approves the month
  • Reconciliation notes with the fix attached show step by step how a careful accountant thinks
  • Correction notes are often worth more than the reports they fed into
  • Approvals that were sent back show which numbers experienced people challenge

What buyers pay for

One invoice, followed across five tools

Buyers want to see how real checking is done, not single documents.

  1. Arrives Supplier invoice comes in by email
  2. Check Matched to the order and delivery
  3. Query Wrong tax spotted and questioned
  4. Fix Supplier sends a corrected invoice
  5. Approve Approved, paid, and the reason kept

What is worth most

The reasoning beats the final figures

A guide to what buyers value, not a price list. Client names, bank details and tax numbers are removed first.

  • Reconciliations with the cause found and the fix attached Highest
  • Corrected figures kept before and after, with a reason Highest
  • Invoice queries with the supplier's reply and the decision High
  • Approvals and expense claims that were sent back High
  • Final accounts, templates and bare ledgers on their own Low
  • Client files under professional secrecy Not yours unless the client agrees

Connected data

A few examples of connected records

Buyers want many kinds of linked records: any check that can be followed across your tools, from a number that looked wrong to the moment it was put right.

A balance that was out. A payment entered twice

    • 1C
    • Excel
…and many more
  • Supplier invoice → wrong tax → corrected invoice → payment
  • Duplicate invoice → spotted → payment held
  • Draft report → review comments → signed-off version
  • Journal entry → second look → approved
  • Odd figure → question → explanation kept
  • Missing receipt → request → claim approved

What stays private

Client confidentiality comes first

Client names and tax numbers

Never included, and neither are bank details

Figures that point to a client

Combined, changed so they cannot be traced, or left out

Payroll

Records for individual people usually stay out entirely

Client work

Stays out unless the client agrees; we can help you ask

Professional secrecy

Your rules and client letters are checked first

Names hidden in notes

Found and removed before anything is prepared

Your records. Your choice. An AI check flags risks, people review them, and nothing is shared until you approve it.

How we protect your information

Two ways to earn

Sell your history once, then keep earning

Two separate offers. Choose one, both or neither.

Yearly income grows as you capture more First sale Yearly sales

Illustration, not a forecast. Yearly payments apply only if your contract says so.

Sell existing records
  • Years of checks and corrections you already have
  • One senior accountant, a few hours here and there around month end
  • A written offer: fixed price, or paid after a later sale
How selling works
Earn from new records each year

We call this Data Farming: keeping better records of work you already do, so there is more to sell each year.

Small process changes, better-set-up tools or a few extra tools that capture more mean even more money every year

  • Small process changes, e.g. pick a reason from a short list when a reconciliation does not match
  • Set up the tools you already use to keep more of the story
  • Add tools that capture more, free of charge if part of the agreed plan
  • No keystroke logging, nothing switched on without your approval
How Data Farming works

How it works

From first chat to offer

  1. 1

    Tell us about your finance team

    Which software and spreadsheets you use, and what you own

  2. 2

    Preliminary valuation

    An estimate within one week, with nothing shared

  3. 3

    Scope and checks

    Client, secrecy and privacy checks, with people reviewing the results

  4. 4

    Offer and your approval

    A written offer. Nothing leaves until you approve it

An honest check

Is this right for your company?

A good fit

  • Several years of records
  • Reconciliation notes and correction history
  • Approval records showing what was sent back
  • Old drafts kept, not overwritten
  • Records that are clearly your own, not only client files

Probably not yet

  • Nearly all records are client work under strict secrecy
  • Only final figures, with old versions overwritten each month
  • Less than a year of history
Before you decide

Questions accountants ask

We keep client finances confidential. Can we take part?

Possibly, but only with records that cannot identify a client and that you are allowed to share. Your duties to your clients still apply.

What exactly would be useful?

Usually the steps, not the client: what did not match, how it was found and how it was corrected. Before and after figures kept together with a short reason are often the most useful part.

Do our clients need to agree?

It depends on your agreements and the records involved. We help you check before anything is included.

We only have final accounts and ledgers. Is that enough?

Often not on its own, because final figures do not show how they were reached. Queries, correction notes or old drafts are worth a look. We will tell you honestly what we find.

Can a finance team inside a company take part, not only a practice?

Yes. A finance team's own reconciliation notes, corrections and approvals are often a good fit, because the records belong to the company. Bank details and payroll for individual people still stay out.
