Your marketplace idea, built out

You came to us wanting a place where staff and students could buy and sell among themselves, instead of relying on group chats and word of mouth. Here is one way that idea could take shape, along with the trade-offs that come with keeping it simple. Nothing here is final. It is a starting point for us to shape together.

Right now, staff and students who want to buy or sell things among themselves (used textbooks, equipment, personal items, and eventually digital files or services) have no dedicated place to do it. It happens informally, through group chats or word of mouth, which makes it hard to find what's available, and leaves no clear way to handle it if something goes wrong.

Here is one way to build the marketplace you described: a simple, dedicated website for your department, where any staff member or student can:

• List an item for sale, for free, with a photo and description.
• Browse and order items without needing to create an account. A buyer just enters their name and phone number when placing an order, so the seller can reach them to arrange the handover.
• Pay however suits them, either in cash when they meet, or through a secure in-app payment option (powered by Paystack) where the buyer approves the charge with their own PIN, right at the moment of handover.

Sellers could set their own pickup or delivery arrangements for each item (for example, "available every Tuesday at the College of Science building"), so buyers know exactly how and where to collect what they've ordered.

Since this would be an internal tool for your own staff and students, not a public marketplace, one option is to keep the approach to trust intentionally lightweight:

• Sellers get approved before they can list anything. Your department's admin would review and approve each seller.
• If something goes wrong, your team handles it, not the software. The platform wouldn't hold anyone's money or automatically referee disputes. If a buyer or seller has a problem, they'd report it, and your admin could step in, using the buyer's name, phone number, and order details as the starting point for the conversation.

This keeps things simple and low-cost to run, but it does mean taking on some real risk in exchange for that simplicity, laid out below so it can be weighed properly.

Every approach has trade-offs, and it felt right to put these on the table now rather than let them surface later:

• No built-in refunds or buyer protection. If a seller takes payment and doesn't deliver, the platform itself wouldn't be able to reverse that. It would become a matter for your admin team to handle directly with the people involved.
• Cash transactions leave no payment record. Only the order details (who ordered what, and their contact number) would be recorded. There's no proof of what was actually paid or exchanged, so disputes on cash sales would come down to what each side says happened.
• A buyer could order an item and never show up. Since no payment would be required to place an order, stock could be tied up by someone who changes their mind. This could be limited by having each seller set a time window (4, 12, or 24 hours) after which an unfulfilled order automatically cancels and the item becomes available again, though it wouldn't eliminate the possibility entirely.
• The system would only work as well as people use it properly. If a seller arranges a sale entirely by phone and skips the app, there's no record of it at all. Software can't force anyone to use it correctly.

None of this is unusual for an internal, low-overhead marketplace like this one, but it felt important to go in with eyes open rather than assume more protection exists than actually would.

There's no cost built into using the platform itself: listings would be free, and there's no plan for the platform to take a cut of any sale. The department's ongoing running costs would mainly come from:

• Hosting the website and its underlying systems (standard, predictable, usage-based).
• Text message notifications to buyers when an order automatically cancels. This has a small real cost per message, and scales with how much the platform is used, so it's worth talking through directly since it's the one recurring cost tied to activity levels.

Could be included from the start: buying and selling physical items, free listings, flexible payment (cash or in-app), pickup/delivery arrangements per item, seller approval, and basic reporting for disputes.

Could come in a later phase: support for selling digital files (like documents or licenses) and services (like tutoring or bookings). These need a different, more careful approach to payment, since there's no in-person moment to exchange money and goods at the same time, so one option is to introduce them as a second phase, once the core marketplace is up and working well. Happy to build it differently if you'd rather have these from day one.

Based on what's described above, a first version like this would come to around GHS 7,000, broken down as follows:

Package	What's included	Price (GHS)
Design & Development	UI/UX design for all user types, plus full frontend and backend development (buyer ordering flow, seller dashboard, admin panel, and all order/inventory logic)	4,200
Integrations & Data	Payment integration (Paystack), SMS notifications, and database setup	1,190
Infrastructure, Testing & Delivery	Hosting setup, full testing and quality assurance, and project coordination through to handover	1,610
Total		7,000

A possible payment schedule:

• 40% to begin work
• 40% when development is complete and testing begins
• 20% on final delivery

Post-launch support (bug fixes and minor adjustments after handover) could be arranged separately as an optional, ongoing service. Pricing available on request.

Not included in this figure: support for digital assets and services (that would be scoped and priced separately, as a second phase, once you've had a chance to weigh in).

Before anything is finalized, a few things would help shape this further:

1. Timeline. Is there a target date you'd like this ready by? Even a rough one helps with planning.
2. Future monetization. As scoped, the platform earns nothing from sales. Would you like to keep it that way, or leave room to introduce a small fee later (for example, once digital goods/services are added)?
3. Seller vetting. What should "approving a seller" actually involve, in your view? For example: checking they're a genuine staff member or student, requiring an ID number, or something else?
4. Notification cost. Are you comfortable with the ongoing cost of text message alerts to buyers, or would you prefer a lower-cost alternative (such as no automatic notification)?
5. Availability expectations. Is there a particular standard of uptime/reliability you'd need from this, or is standard web hosting enough?
