The verdict in three sentences
For a 12,000-customer PAYGo operator in Kinshasa, billing software is the heart of the business model: every point of collection rate is worth tens of thousands of dollars a year. A custom platform at USD 40,000 to 90,000, connected to the three mobile money operators and to kit locking, beats a per-customer licence beyond 8,000 to 10,000 active customers. The realistic goal is moving from 80% to 92% collection within 12 months.
What a PAYGo platform must do in the DRC
Many off-grid solar operators active in Central and East Africa are financed or headquartered in Dubai, while customers pay in Kinshasa. The customer buys a kit (panel, battery, lights, sometimes a TV) through small daily or weekly instalments. The software must collect via mobile money, issue an unlock code or unlock the kit remotely, send reminders before cut-off and pay field agents on commission. In Kinshasa, field reality matters: unstable networks, multi-SIM customers, payments in USD and Congolese francs.
| Feature | Field requirement in Kinshasa | Impact on collections |
|---|---|---|
| Mobile money collection | M-Pesa, Orange Money, Airtel Money, automatic reconciliation | Payment in 30 seconds, fewer missed instalments |
| Remote locking | Offline tokens or GSM commands | Direct incentive to pay |
| SMS reminders | D-2, due day, D+1 before lock | +4 to +6 points as an order of magnitude |
| Multi-currency | USD and CDF with daily rate | Avoids exchange disputes |
| Agent app | Offline-first, delayed sync | Visits focused on late payers |
| Agent commissions | Automatic calculation on sales and collections | Agents incentivised on portfolio quality |
| PAR dashboard | Portfolio at risk by zone and agent | Kit repossession decisions |
Licensed platform or custom build: 2026 prices
Specialised PAYGo platforms usually charge per active customer per month. Great for starting out, expensive at scale. Custom needs upfront investment, but marginal cost per customer becomes close to zero.
| Item | Licensed PAYGo platform | Custom platform |
|---|---|---|
| Setup | USD 5,000 - 15,000 | USD 40,000 - 90,000 |
| Recurring cost | USD 0.50 - 1.50 per active customer per month | USD 6,000 - 12,000 a year (hosting and maintenance) |
| Annual cost at 12,000 customers | USD 72,000 - 216,000 | USD 6,000 - 12,000 |
| DRC mobile money integration | Vendor-dependent, often partial | All 3 operators included |
| Time to go live | 1 - 3 months | 5 - 8 months |
| Mobile money transaction fees | 1 - 3% (same in both cases) | 1 - 3% |
| Customer data ownership | Shared with vendor | Full |
Estimated tipping point: beyond 8,000 to 10,000 active customers, custom pays back in under 18 months. Below that, stay on a licence and tighten your reminder process.
Mini case study
Patrick, COO of a solar kit distributor run from Dubai with operations in Kinshasa, manages 12,000 customers paying USD 12 a month on average, so USD 1,728,000 billed a year. His collection rate is 80%. With a custom platform at USD 75,000, automatic reminders and remote locking, he reaches 90% within 12 months: 10 points of collection mean USD 172,800 more cash. He also drops a licence at USD 0.80 per customer per month, or USD 115,200 a year. After USD 10,000 of annual maintenance, the project pays back in about 4 months.

How much does PAYGo solar billing software cost?
A custom platform costs USD 40,000 to 90,000 depending on integrations and the agent app. A licence starts at USD 5,000 plus USD 0.50 to 1.50 per active customer per month.
Which mobile money operators should be integrated in Kinshasa?
M-Pesa (Vodacom), Orange Money and Airtel Money cover most customers. Each integration takes 3 to 6 weeks, merchant contract included.
Does remote locking work without network coverage?
Yes, with tokens entered on the kit, generated after each payment and sent by SMS. The kit locks itself when credit expires, without a permanent connection.
What collection rate should we target?
Well-equipped operators reach 88 to 93%, as a 2026 order of magnitude. Below 80%, the PAYGo business model becomes fragile, which investors in Dubai watch closely.
How are field agents paid in the software?
The platform calculates a sales commission (often USD 5 to 10 per kit) and a bonus on their portfolio's collections, paid weekly via mobile money.
