The verdict in three sentences
A mall with 85 to 150 units managed in spreadsheets leaks money in three places: missed rent escalations, poorly allocated service charges and late payments that often reach 8 to 12 % of billed rent. Custom commercial property software links leases, billing, collections and footfall counters in one system, whether your portfolio sits in Abidjan or Dubai. At Kolonell, this kind of project sits between a medium-complexity application (4,000,000 to 7,000,000 FCFA, i.e. 6,100 to 10,670 EUR) and a complex one, depending on integrations.
What spreadsheet management really costs
Take a mall manager in Dubai overseeing two community malls with 140 units. Retail rents in Dubai community malls run roughly AED 150 to 450 per square foot per year in 2026 (order of magnitude), with service charges of AED 25 to 60 per square foot on top. A 1,000 sq ft unit therefore bills AED 175,000 to 510,000 a year. Missing a 5 % escalation on 20 leases costs hundreds of thousands of dirhams.
| Item | Spreadsheet management (2026 order of magnitude) | With dedicated software |
|---|---|---|
| Late payments | 8 to 12 % of billed rent | 4 to 6 % with automated reminders |
| Escalations applied on time | 70 to 80 % of leases | 100 %, schedule computed at signing |
| Invoice issue delay | 5 to 8 days into the period | Day 1, email and WhatsApp delivery |
| Annual service charge reconciliation | 6 to 10 weeks of work | 1 to 2 weeks, allocation keys preconfigured |
| Payment matching (bank, cards, post-dated cheques) | Manual, line by line | Automatic matching by tenant reference |
| Tenant sales reporting | Phone and email chasing | Tenant portal with mandatory monthly upload |
Modules a mall actually needs
Mall software is not a residential rent-collection tool. It must handle commercial leases with base rent, turnover rent above a breakpoint, rent-free fit-out periods, key money, plus common charges: security, chilled water and district cooling, cleaning, parking and centre marketing. In Dubai, it also has to track Ejari registration dates and post-dated cheque schedules.
| Module | Key function | Complexity |
|---|---|---|
| Units and lease register | Areas, brands, dates, clauses, security deposits, Ejari | Simple |
| Billing and escalations | Base rent, turnover rent, annual escalation | Medium |
| Service charges and reconciliation | Budget, per-sq-ft or weighted keys, year-end statement | Medium |
| Collections and reminders | Bank transfer, cards, PDC tracking, escalating reminders | Medium |
| Tenant portal | Sales reporting, invoice downloads, maintenance tickets | Medium |
| Footfall | Daily import from entrance counters, conversion per brand | Complex with several vendors |
| Management dashboard | Occupancy, average rent per sq ft, arrears, vacancy | Simple once data is clean |
The footfall module pays off in lease renewals: crossing entrance counts with reported sales gives an occupancy cost ratio per tenant (rent plus service charge divided by sales). Above 12 to 15 % for a fashion retailer, the risk of non-renewal rises and leasing can act early.
Budget and timeline
A first release covering leases, billing, escalations and collections is a medium-complexity application: 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), delivered in 10 to 14 weeks. Adding the tenant portal, footfall integration and multi-key reconciliation moves it into the complex band: 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR). Maintenance then runs 75,000 or 120,000 FCFA per month depending on support level. Hosting, historical data migration and accounting connectors are quoted separately.
For comparison, enterprise commercial property suites used in the Gulf commonly cost AED 150 to 600 per user per month in 2026 (order of magnitude), plus implementation fees, and rarely fit a two-mall operator's exact clauses.
Mini case study
Omar, operations manager of two community malls in Dubai with 140 units, bills AED 21,000,000 of rent and service charges a year. Late payments sit at 10 %, so AED 2,100,000 is permanently outstanding, and about 3 % of billings (AED 630,000) end up written off or settled at a discount. Last year 18 leases missed a 5 % escalation, roughly AED 180,000 lost.

With a medium-complexity application in the 4,000,000 to 7,000,000 FCFA band (6,100 to 10,670 EUR), automated reminders bring write-offs down to 1.5 % (AED 315,000 saved) and every escalation is applied (AED 180,000 recovered). Annual gain: about AED 495,000, plus two days a month freed for the credit controller. Even with maintenance at 120,000 FCFA a month, payback comes within the first quarter.
FAQ
Can the software handle turnover rent above a breakpoint?
Yes. Each month it bills the higher of base rent or the agreed percentage of reported sales, typically 5 to 8 % depending on the category. Tenants upload sales in their portal before the 10th.
How are post-dated cheques and mobile payments handled?
In Dubai, each PDC is logged with its due date and the system flags bounced cheques within 24 hours. In Abidjan, invoices carry a Wave or Orange Money link with a unique reference for automatic matching.
How long does migrating from spreadsheets take?
Allow 2 to 4 weeks to clean and import 140 leases, 24 months of history and deposits. Migration is quoted separately because it depends on the state of existing files.
Can we connect our existing footfall counters?
If the vendor provides a file export or an API, a daily import takes 1 to 2 weeks to set up. Without an export, weekly manual entry works until sensors are replaced.
Who owns the software?
The mall owns the code and data, hosted on a dedicated server. There is no per-unit fee, unlike SaaS tools charging AED 15 to 40 per unit per month.
