For self-storage yard owners

Run your storage yard from one screen.

Customers book and pay online, invoices and reminders go out on their own, and your accountant gets a Pastel-ready month-end on the 1st. Built in South Africa, for South African yards.

Running a 194-unit yard in KwaZulu-Natal since October 2026.

Owner's overview: 85% occupancy, R40,320 monthly recurring revenue, R9,652 outstanding and 2 bookings waiting for review

What it takes off your plate

Less admin. Fewer arrears. No spreadsheets.

Bookings while you sleep

Customers choose a unit, upload their ID, pay the deposit and first month, and sign the lease online at any hour. You check the documents and approve.

Rent that collects itself

Invoices go out on the 1st. Card and debit-order tenants are collected automatically, and late payers get reminders, late fees and letters of demand on your schedule.

Month-end in one click

The ledger checks itself, and your accountant receives the VAT register, debtors' age analysis and a Pastel journal by email on the 1st of every month.

Online booking

Let customers book and pay without phoning you.

Your own booking page shows what's free, by size, drawn to scale. Customers can book a unit that's coming free next month, too.

  • Card payment through PayFast: deposit and first month up front
  • ID, proof of address and bank letter uploaded with the booking
  • Lease signed electronically, with a signed copy emailed to the customer
  • Prefer to ask first? Enquiries land in the same dashboard

Approvals

Everything you need to say yes, on one page.

Each paid booking arrives with the customer's details, documents and payment confirmed. Approve it and the lease, the first invoice and the welcome email are done.

  • Documents open right there, with no email attachments to dig for
  • Approve, reject or refund with the reason sent to the customer
  • Separate logins for you and your accountant, each seeing only what they need

Billing & collections

Stop chasing rent.

Monthly invoices go out automatically. Recurring card and debit-order tenants are collected on schedule, and the system follows up when a payment doesn't arrive.

  • Friendly reminders, then a formal letter of demand, on the days you set
  • Late fees worked out for you, capped, and waivable per invoice
  • Failed card charges and returned debit orders flagged, with the tenant told how to pay
  • Edit the wording of reminders, receipts and booking emails yourself

Tenant portal

Tenants help themselves.

Every tenant gets a login to see their units, invoices and payments. That means fewer phone calls and fewer "please resend my invoice" emails.

  • Pay an invoice by card in two taps
  • Switch to a recurring card or debit order
  • Ask to move to a bigger or smaller unit
  • Give notice to vacate, confirmed by email

Month-end

Your accountant will thank you.

On the 1st, the month is checked, closed and emailed to your accountant, ready to post. If something doesn't reconcile, nothing is sent until it's fixed.

  • Sales & VAT register, receipts, debtors and age analysis
  • Deposits held and income received in advance
  • A summary journal that imports straight into Sage Pastel
  • Closed months are locked, and corrections go through credit notes

Built for South Africa

Not an overseas system with rands bolted on.

Most storage software is built for the US, UK or Australia. This was built for how yards here actually run.

PayFast

Once-off and recurring card payments through South Africa's most-used payment gateway, in your own merchant account.

Debit orders & EFT

Debit-order and EFT tenants live alongside card payers, with returned debit orders handled properly.

POPIA Built in

Privacy notice, consent records, retention periods and a process for access and deletion requests.

Electronic signatures

Leases signed and countersigned online with a one-time code, kept with a full record of who signed and when.

VAT & Pastel

15% VAT on every invoice, a VAT register each month, and a journal your accountant imports into Pastel.

Local support

Built and supported by a South African developer who already runs it for a live yard.

And the rest

All the everyday jobs, covered.

  • Several sites, with blocks, floors and unit sizes
  • Unit transfers: upgrades now, downgrades from the 1st
  • Notice to vacate and automatic move-out
  • Deposits: held, refunded or forfeited
  • Fixed-term or month-to-month rentals
  • Advance bookings for units coming free
  • Prepayments with an optional discount
  • Add-on services on the monthly invoice
  • Credit notes instead of deleting invoices
  • Reports: occupancy, revenue, bookings
  • Audit log of every important change
  • Your branding, logo and domain

We bring your existing tenants across, switch on billing, and you start taking bookings online.

One monthly fee covers it all Hosting, daily backups, security updates, new features as they're released, and support from the person who built it.

Questions

Frequently asked

What does it cost?

A fixed monthly fee in one of three tiers, set by the size of your yard. It covers hosting, backups, updates and support. There's also a once-off setup fee for bringing your yard, tenants and branding across. There's no per-booking commission; card fees are between you and PayFast. Email us for a quote.

Can my tenants still pay by EFT or cash?

Yes. Staff record EFT and cash payments against invoices, and those tenants still get invoices, reminders and portal access.

What happens to my existing tenants?

We import them, with their units, rates and what they owe, so billing carries on from where your current system or spreadsheet leaves off.

Who owns the data?

You do. Under POPIA you're the responsible party and we act as your operator. If you ever leave, you get a full export of your records.

Will it look like my business?

Yes. The booking page, tenant portal, emails, invoices and lease carry your name, logo and colours, on your own web address.
