Moving your loan book off spreadsheets

Signs you've outgrown the spreadsheet

None of these is a crisis by itself. Together they mean the spreadsheet has become the riskiest part of your operation.

• Payoffs take an hour and you still double-check them
• Draw requests live in text messages and email threads
• Only one person really understands the formulas
• Month-end means reconciling the loan sheet with the books
• Partners ask "where are we?" and the answer takes a day
• Borrowers email to ask for their balance

Step 1: Pick a cutover date

Choose a date — often a month-end — as the point where the new system becomes the record. Everything before that date is history you bring in; everything after it happens in the new system. A clean date keeps you from running two systems in parallel for months.

Step 2: Gather the loan data

For each active loan, pull the source documents, not just the spreadsheet row. The note and closing statement are the authority; the spreadsheet is a summary that may have drifted.

• Borrower, entity, guarantors, and property
• Original principal, commitment, and holdback
• Note rate, default rate, day count, and interest basis
• Funding date, maturity, and extension terms
• Draws funded to date with dates and amounts
• Payments received with dates
• Fees charged and any unpaid late fees
• Capital source for each loan

Step 3: Verify balances before you trust them

For each loan, recompute the principal balance and interest paid-through date from the documents and payment history. Compare to the spreadsheet. Differences are common, and finding them now — before you quote a payoff from the new system — is the whole point.

Start with the loans closest to maturity or most likely to pay off soon. Those are the ones where an error will surface first.

Step 4: Set up capital and accounts

Enter your capital accounts and credit lines with balances as of the cutover date, and link each loan to the source that funded it. If you'll keep your books in the same system, set up your chart of accounts and opening balances with your accountant.

Step 5: Bring your team and borrowers over

Decide who needs access and what they should be able to do. Then tell borrowers how they'll check balances and request draws and payoffs going forward. A short email with the new process, sent before the next payment date, saves a lot of phone calls.

Step 6: Run one month side by side, then stop

For the first month, check the new system's interest and balances against your own calculation for a handful of loans. Once they agree, stop updating the spreadsheet. Keep a read-only copy for history, but don't let it become a second source of truth.

What to expect

The data gathering is the hard part, and it's worth doing carefully. Most lenders find at least one discrepancy in the process — a draw recorded on the wrong date, a payment applied twice, a fee never charged. Fixing those is a benefit of the move, not a cost.

Bring paid-off loans or not?

Many lenders only migrate active loans and keep paid-off loans in the old spreadsheet for reference. That's the fastest path. If you want full history in one place — for reporting on lifetime returns, or for tax records — bring paid-off loans in after the active book is settled, so they don't slow down the cutover.

Either way, keep the original documents in an organized folder. The new system is only as reliable as the data you put into it, and the documents are what you'll go back to if a number is ever questioned.

A note on the books

If your accountant keeps your books today, involve them before the cutover date. Agree on opening balances and on how loan activity will flow to the general ledger from then on, so your first month-end in the new system closes cleanly. This guide is general information, not accounting advice.
