TL;DR - Quick Summary

A business interruption claim rests on the numbers before and after the loss: what the business earned, and what expenses kept running while it was down. Convert your bank statements to a CSV to build the pre-loss revenue baseline from deposits, show the drop during the shutdown, and total the continuing and extra expenses.

What a business interruption claim has to prove

A business interruption claim is a before-and-after argument: the insurer wants to see what the business was earning, what happened to that income when operations were disrupted, and which costs carried on regardless. Proving it takes financial records covering one to two years before the loss, and while the profit-and-loss statements and tax returns lead, the bank statements are the independent corroboration, the secondary proof point an adjuster turns to when a figure is questioned. That makes the statements worth organizing well. Converting them to a CSV turns the deposits and payments into sortable data you can total by month, which is the form a claim's revenue baseline and expense schedule actually take.

The pre-loss revenue baseline

The heart of the claim is what the business would have earned but for the loss, and that projection is built from the period before it. Insurers typically take one to two years of pre-loss income and derive a monthly average to represent expected earnings, so the baseline has to be solid. Totaling the deposits month by month in a converted CSV gives you that history in a form you can average and defend, and it lets you strip out what is not operating revenue, a loan draw, an owner contribution, or a transfer, so the baseline reflects the business, not incidental cash. A clean, month-by-month revenue trend is what makes the projected loss credible.

Showing the drop during the period of restoration

Against that baseline you set the actual results during the period of restoration, the time the business was impaired. The deposits during those months, totaled from the converted statements, show how far revenue fell below the projection, and the gap is the lost income at the center of the claim. Presenting it as a month-by-month comparison, expected versus actual, is far clearer than a single lump figure, and it maps directly to the monthly profit-and-loss statements an insurer asks for throughout the interruption. The converted data is what lets you produce that side-by-side quickly rather than reconstructing each month from statement pages.

Continuing and extra expenses

Lost revenue is only part of the claim. Business interruption covers the net income that would have been earned plus the normal operating expenses that continued even while operations were suspended, and those continuing costs, rent or mortgage, loan payments, insurance premiums, utilities, essential payroll, and equipment leases, often make up a large share of the claim. Sorting the converted payments surfaces exactly which charges kept clearing during the shutdown. Many policies also cover extra expenses incurred to mitigate the loss, temporary relocation, equipment rental, overtime, or marketing to win business back, and filtering those out of the same data documents them for the claim.

Corroborating the P&L, and privacy

Because the bank statements exist to back up the profit-and-loss statements, keeping the converted transaction data alongside them gives an adjuster or a forensic accountant a clean trail from each claimed figure to the account it came from, which is what resolves the discrepancies that slow a claim. Since these are the business's full financial records, statements are processed to build the CSV and then deleted automatically, with nothing retained on a server afterward. For an owner, public adjuster, or accountant assembling the claim, that pairing of fast month-by-month totals and automatic deletion keeps the work quick and the records confidential.

How it works

  1. Convert the statements: Convert one to two years of pre-loss statements plus the interruption-period statements into a CSV.
  2. Build the baseline: Total the deposits by month before the loss and average them for the expected-earnings baseline.
  3. Show the drop: Total the deposits during the period of restoration and compare month by month against the baseline.
  4. Total the expenses: Filter the payments for continuing operating costs and for extra mitigation expenses, and total each.
