How to migrate your loans from Excel to loan management software

Almost every lender who buys loan management software already has a loan book in Excel. The migration is the part people worry about, and it is more manageable than it looks if you follow an order. The main risk is not the software; it is discovering, during import, how inconsistent the spreadsheet was. That is a good thing to find out, as long as you plan for it.

If you are still deciding whether to move at all, our Excel vs loan management software comparison sets out the trade-offs honestly.

Before you start: define what "done" looks like

Migration is finished when, for every active loan, three things match your old records: the outstanding balance, the next installment due, and the payment history. Everything else is secondary. Write that down as your acceptance test.

Step 1: take a clean copy

Never work on the only copy of your loan book. Save a dated copy of the spreadsheet as read-only and do all preparation on a duplicate.

Step 2: decide what to migrate

You do not always need everything. Common approaches:

• Active loans only, with full payment history. Best for accuracy; more effort.
• Active loans with opening balances. Each loan starts in the new system with its outstanding principal, interest and the next due date, and history is kept in the old file. Faster, but you lose per-loan payment history.
• Everything, including closed loans. Only if you need the history in the system for reporting.

Choose deliberately, and keep the old file as an archive.

Step 3: clean the data

This is the longest step, and it pays off. Look for:

• Duplicate borrowers, with different spellings of the same name.
• Missing fields: phone numbers, ID numbers, dates.
• Inconsistent dates: text, different formats, impossible values.
• Inconsistent amounts: numbers stored as text, currency symbols, mixed units.
• Loans without a clear product or interest method.
• Balances that do not reconcile to payments.
• Status confusion: loans marked active that are actually closed or written off.

Fix the data in the spreadsheet so that each loan has one row and each borrower one record.

Step 4: define your loan products in the new system

Before importing loans, create the products they belong to: interest method, rate, fees, term limits and repayment frequency. If your old loans used inconsistent terms, decide which product each belongs to. See how to calculate loan interest if you need to check which method a loan really used.

Step 5: map your columns

Compare your spreadsheet's columns with the import template's fields: borrower name, contact, ID number, loan amount, interest rate, term, start date, product, payments and so on. Rename and reorder your columns to match. Decide how to handle fields the template does not have, such as custom fields you can add on borrowers or loans.

Step 6: import a small sample first

Import 10 to 20 loans, including awkward ones: an early payoff, a late payment, a partial payment, a renegotiated loan. Check each against your records: schedule, balance, next due date. If the numbers differ, find out why before importing more. The cause is usually a data issue or a difference in interest method.

Step 7: reconcile

For the sample and then the full import, compare:

• Total outstanding principal in the old file and in the new system.
• Number of active loans.
• Overdue amounts and the number of overdue loans.
• Interest income to date, if you migrate history.

Differences of a few cents can come from rounding. Anything larger needs an explanation.

Step 8: import the full book

Import the rest, in batches if the system prefers. Fix rows the validation report rejects, and re-import those.

Step 9: run in parallel briefly

For a short period, such as one or two collection cycles, record new payments in both systems, or record in the new system and check against the old. Confirm that balances stay in step. Then stop updating the old file and mark it archived.

Step 10: train the team and switch

Give staff the documentation and a short practice session on real tasks: recording a payment, printing a receipt, finding overdue loans. Set a clear cut-over date, after which the old spreadsheet is read-only.

Common problems

• Balances differ because the old spreadsheet used a different interest method than the product you chose. Match the product to the old method or decide on the change deliberately.
• Dates in different formats shift installment dates. Standardize before import.
• Payments recorded against the wrong loan. Reconcile per loan, not only in total.
• Closed loans mixed in with active ones. Filter and check the status.
• Staff keep updating the old file. Make it read-only on the cut-over date.

Migration checklist

• Dated read-only copy saved
• Scope decided (active only, opening balances, or history)
• Data cleaned and de-duplicated
• Products created in the new system
• Columns mapped to the template
• Sample imported and checked
• Totals reconciled
• Full import completed and errors fixed
• Parallel run finished
• Staff trained
• Cut-over date set and old file archived

Migrating to LoanTabs

LoanTabs gives you two routes. You can import borrowers by CSV, using a template, with a validation report and a downloadable list of any rows that failed. Or you can use the free Excel starter template to import borrowers, loans and payments together; it supports flat, reducing balance and interest-only loans. Both are described in the borrower management and loan management solution pages, and in the Admin configuration guide. Start with the free 30-day trial to test a sample with no commitment.

FAQ

How long does it take to migrate from Excel?

For a small lender with clean data, a few days. For a large book with messy data, plan for weeks, most of it spent cleaning.

Can I import loans and payment history?

Yes. The LoanTabs Excel starter template imports borrowers, loans and payments.

What if my spreadsheet is a mess?

That is normal. Clean it in the spreadsheet first, import a small sample, and fix problems as you find them. Cleaning is the value, not a cost.

Should I migrate closed loans?

Only if you need them for reporting. Otherwise keep them in the archived spreadsheet.

Will I lose my data if I switch software again later?

Not if you choose a product that exports your data. Check this before you commit.
