Berlvis Books

Berlvis Books helps a business record sales, expenses, customer balances and payments in one operating record, without forcing the owner to think like an accountant.

The problem

A business can trade all day and still be unable to explain what was sold, what was paid, who still owes money or whether the day actually balanced.

Available now

What Books can do today.

  • Record multi-item sales with discounts and split cash or transfer payments.
  • Track customers, balances, partial payments and the sales those payments settle.
  • Review daily, weekly and monthly reports and export business records.
  • Preserve correction and archive history instead of silently deleting financial records.
Being proven

What we are testing before saying more.

  • Making the first week of record keeping clear enough for a business that has never kept formal books.
  • Improving debt allocation, reversals and account history without weakening earlier records.
Boundaries

What this product does not claim.

  • Books is not an accountant and does not file tax returns or provide financial advice.
  • It is designed for owner-operated businesses, not companies that already run a full finance department.
  • Reports are only as complete as the transactions the business records.

Record standard

Append, correct, preserve

Financial history is corrected visibly rather than silently overwritten.

Current work

Helping a small business complete its first daily close correctly and keep using the record long enough for it to become useful.

Latest verified update: Debt allocation, partial-payment and correction flows were strengthened while preserving earlier transaction history.
