The verdict in three sentences
For a Dubai shopping mall with 80 to 250 tenants, custom tenant management software costs $30,000 to $90,000 in 2026 (about 110,000 to 330,000 AED, or 28,000 to 83,000 EUR), with a 4 to 6 month rollout. The main gain comes from turnover rent, service charge budgets and reconciliations and a tenant portal that speeds up sales reporting. In comparable projects, collection delays drop by about 20 %, freeing significant cash.
Why Excel breaks beyond 80 tenants
A mall lease combines a guaranteed base rent, a turnover rent (often 5 to 12 % of sales above a breakpoint), annual escalation, a share of common area charges and sometimes a marketing levy. Multiply by 150 tenants, each with amendments, and monthly billing becomes high risk. Service charge reconciliation gaps are the top source of tenant disputes.
| Module | Function | Indicative 2026 cost (USD) | Measured effect |
|---|---|---|---|
| Lease register | Units, areas, amendments, expiries | $5,000 - $12,000 | Zero missed renewal dates |
| Turnover rent | Breakpoints, rates per tenant, sales reports | $7,000 - $18,000 | Calculation in 1 day instead of 6 |
| Service charges | Apportionment keys, budget, quarterly demands | $6,000 - $16,000 | Charge disputes halved |
| Billing and dunning | VAT-compliant invoices, staged reminders | $4,000 - $12,000 | Collection delay cut by 20 % |
| Tenant portal | Sales reporting, invoices, maintenance tickets | $5,000 - $20,000 | 85 % of sales reported on time |
| Dashboard | Occupancy, occupancy cost ratio, arrears | $3,000 - $12,000 | Monthly board review in 1 h |
A core of leases, turnover rent and billing starts around $30,000. The full version with portal, service charge reconciliation and accounting link reaches $70,000 to $90,000.
Custom, real estate ERP or generic software: comparison
| Criterion | International real estate ERP | Standard lease software | Custom by Kolonell |
|---|---|---|---|
| Upfront cost | $120,000 - $300,000 | $8,000 - $20,000 | $30,000 - $90,000 |
| Annual licenses | $25,000 - $60,000 | $6,000 - $15,000 | $4,000 - $9,000 maintenance |
| Turnover rent | Yes, heavy configuration | Rarely | Native, your lease rules |
| Local tax (UAE VAT 5 %) | Paid adaptation | Variable | Built in |
| Portal in English and Arabic | Costly option | Rare | Included |
| Rollout time | 9 - 15 months | 1 - 3 months | 4 - 6 months |
The international ERP makes sense for a multi-country landlord. For one or two malls, custom software offers the best balance between coverage and total cost.
The hidden lever: sales reporting
Turnover rent depends on tenants' monthly sales reports. By email, 30 to 40 % arrive late, which delays billing by a month. A portal with automatic reminders, POS file import and a consistency check (variance above 25 % vs the previous month) pushes on-time reporting above 85 %. Cross-checking with footfall counters also helps spot under-reporting.
Mini case study
Karim, general manager of a 140-tenant mall in Dubai, bills about $2.6 million of rent and charges a month. Average collection time was 38 days. After deploying custom software for $62,000, delivered in 5 months, it fell to 30 days, a 21 % drop. Eight fewer days of billing in the pipeline frees about $690,000 of cash. At a 6 % annual financing cost, that saves roughly $41,000 a year. Add 2 accounting FTEs redeployed (about $65,000 a year) and recovered under-reported turnover rent estimated at $48,000 in year one. Payback: under 14 months.
