A ground-rent platform for Oyo State Housing Corporation.

Ground rent was paid manually, and tracking was weak. Payers struggled to pay, and staff struggled to track debtors and records.

I was the lead product designer, working directly with the developers and the client. I owned the product design and direction end to end:

• UX research and journey mapping
• UI design and the design system
• Working with developers through build

• Research. I spoke to the client and stakeholders to understand how ground rent worked.
• Journeys first. I mapped the user journeys before designing any screens.
• Testing before build. I tested the designs with both the client and users before build, which led to revisions.

Constraints I designed within

• Government rules and approvals
• Payment gateway limits
• Existing records and data
• Low-bandwidth and older devices

One web platform where residents pay ground rent and staff track what is owed.

For payers

• Three types of user are covered: ground rent payers, debtors and integrated occupants.
• Sign-in uses a unique ID and password, with recovery by email if either is forgotten.
• A dashboard shows each user's lands. Debtors can see the amount owing and set up a repayment plan.
• Integrated occupants submit an integration form, which is verified, inspected and approved before an invoice is generated.

Paying rent

• The system generates an invoice ID. The user taps Pay Now and gets a payment reference ID.
• Payment is made by card, transfer or bank. The gateway confirms it, and the system logs a transaction ID.
• A receipt is generated and given a receipt number. If a payment fails, the user returns to the invoice with feedback.

For staff

• A Super Admin can view system metrics, notifications and flagged user activity.
• Admins can search and filter users, create or import accounts, and send password reset links.
• Admins can view invoices and payment statuses, trigger new invoices, and resend failed payment links or receipts.
• Login history, changes to user data and exportable audit logs support tracking and records.
• Payment rules can be defined per estate, previewed, saved and applied to all associated users or land parcels.

The platform went live.
