Build or buy a loan management system: what to ask a vendor

The short answer

Buy a loan management system when your products fit its interest methods, schedule changes and regulator reports without workarounds, and when the vendor can show each one live. Build when the loan is the business. Ask before you sign. Interest, schedules, reports and export come first.

Settle what makes your loan product different

Write the product on one page. List the interest method, the repayment frequency, the fees, the penalty rule and who approves what at each loan size. Most lenders find the product sits closer to standard than they believed, and that discovery alone can save the cost of a build.

Mark what is truly yours. Be strict, because every special case you keep adds to the vendor’s quote or to the scope of a build. A weekly group loan with centre meetings differs from a monthly secured business loan, since the collection point, the surety and the default process all change with it.

Reports and screens are cheap to vary. Interest accrual and schedule regeneration are not, so if your difference sits there, look harder at a build, because that engine is the core a vendor cannot bend.

  • Interest method and day-count rule
  • Repayment frequency and grace
  • Fees, penalty and rebate rules
  • Approval levels by loan size

Ask about interest and schedules

Ask for live schedules, not slides. Use one reducing balance loan, one flat rate loan and one with a broken first period, all taken from your real book.

Then change them. Make a part-prepayment, shift a due date and restructure one loan, then check that the old schedule is kept and the new one starts from the right date.

Suppose a regulator or a board decision alters the penalty rate mid-year, and ask whether the system can apply it to new loans only. A yes needs a demonstration on a loan that already has instalments posted against it, in front of your operations head.

Ask about regulator reports and audit trails

Every lender files something. Ask for the exact file formats your regulator and bureaus accept, whether overdue ageing, provisioning, portfolio at risk or credit bureau uploads, then open a sample file yourself.

Check who maintains those formats when the regulator changes them, and who tests the new file before your next filing date falls due. Check how fast the vendor delivered earlier changes. Paid extra, or in the plan?

An audit trail should name who changed a rate, a schedule or a receipt, and when, with the old value and the new value side by side. Edit a loan and read the log. Then try to edit the log itself.

  • Credit bureau upload format
  • Overdue ageing and provisioning report
  • Change log with user and time
  • Maker and checker approval on edits

Ask about data export and exit

Your loan data will outlive the software. It holds borrower histories, guarantor links and years of receipts, and you may need to produce it for a court or an auditor long after the contract ends.

Request a full export in CSV or SQL form carrying schedules, receipts, charges and scanned documents, and ask what that export costs once the contract is over. Get the figure in writing.

Ask where the data is hosted and who holds the backups, and whether your team can query the database for its own reports. Otherwise every question about a borrower’s history, such as a missed instalment in March, goes through a support ticket and a wait of unknown length. Hesitation over export is itself the answer.

When a custom build is justified

A build suits an unusual product. It also fits when no package offers the integrations you need, or when your volumes and rules will outgrow a configured tool within a few years.

A build costs time at the start. It needs an owner who writes rules clearly, and a plan for support after launch, since the code, the hosting and the bug fixes are now yours to maintain.

Before choosing, run the same three-loan test on a vendor demo and on a prototype scope, then list every gap you found in each. Compare the two lists. Then decide.

Vendor question checklist

Single sheet, four blocks. The blocks cover interest and schedules, reports, audit and security, and data export, with one question on each line and room for the vendor’s answer. A box shows whether the vendor demonstrated it on screen, and a last box records a build, buy or workaround decision.

Questions owners ask

Should a small lender build its own loan system?

Rarely. A small lender is usually better served by a configured product with a clean export option and a vendor who answers quickly. Build only when the product is unusual, the integrations are missing, or the volumes will soon outgrow any configured tool.

What is the first test of a vendor’s system?

Ask them to build the schedule for three of your real loans, then change one with a prepayment and a restructure. Live behaviour matters more than slides.

How do we avoid being locked in?

Get the export format in writing. Test it during the trial, confirm who owns the database, and ask what becomes of your data if the vendor closes down or is bought by another company.

Who maintains regulator report formats?

Put it in the contract. The vendor should name the maximum time allowed to deliver a changed format, and say who pays when the regulator revises a template. A custom build puts this job on your team.
