Finance → TPS → Contracts · Amortisation Schedule · At-Risk Contracts A TPS contract bills from an amortisation schedule, not from a recurring rent charge. The schedule is generated once from the contract terms and then drives every period’s billing.

​
The amortisation schedule

Each scheduled instalment carries: The schedule is the contract’s promise. Actual billing and payment are measured against it, which is what makes “behind schedule” a precise statement rather than a judgement.

​
Generation runs

Schedules and their invoices are produced by generation runs. The Generation Runs page shows each run and its outcome; Monthly Balances shows the resulting position per contract per month.
1

Verify contract terms before generating

Loan amount, deposit, rate, term and start date. A schedule generated from wrong terms has to be regenerated, and any invoices it produced have to be corrected.
2

Generate the schedule

Produced once per contract from its terms.
3

Review the schedule

Check the first and last instalments and the closing principal. A closing principal that is not zero at term end means the terms and the schedule disagree.
4

Bill from it

Each period’s instalment becomes an invoice, settled and allocated like any other. See Invoices.

​
Payments and allocation

Instalment invoices are settled by payments and allocations exactly like rental invoices. What differs is the interpretation:
  • On schedule — cumulative principal paid matches the schedule’s expectation for the date.
  • Ahead — the beneficiary has paid more principal than scheduled.
  • Behind — arrears against the schedule, which is what drives at-risk status.

​
Overpayments and prepayments

An overpayment on a TPS contract is not the same as an overpayment on a rental account. Applied naively — by simply pulling principal forward without re-amortising — a prepayment can leave the borrower paying substantially more interest than the shortened schedule would justify. Treat prepayment handling as a scheme policy decision, and record the intent explicitly rather than letting a generic allocation rule decide it.

​
At-risk contracts

At-Risk Contracts lists contracts in arrears against their schedule, with the size and age of the shortfall. It is the TPS equivalent of the debt-aging report, measured against amortisation rather than against invoice due dates. Work it the same way you work arrears elsewhere:
1

Sort by exposure

Largest net loan balance with the largest schedule shortfall first.
2

Check whether it is a payment problem or an allocation problem

Money received but unallocated shows as arrears. Fix allocation before contacting anyone.
3

Check the default state

A contract approaching default criteria needs a different conversation from one a month behind. See Compliance & ownership.
4

Record the outcome

Notices, arrangements and commitments belong on the record, not in an inbox.

Contract statuses

TPS uses the shared lease-status vocabulary plus three of its own: See the full lease-status reference.
