The verdict in three sentences
For a solar equipment manufacturer in New York working with 120 installer resellers, a custom reseller portal costs roughly 60,000 to 140,000 USD in 2026 with a local agency, over 12 to 16 weeks. Off-the-shelf PRM tools (partner relationship management) charge 40 to 100 USD per partner per year, plus configuration that is often underestimated. Custom makes sense when tiered partner pricing, deal registration and deal protection sit at the heart of your channel model.
The modules that make an installer network sell
An installer reseller wants three things: an up-to-date net price, assets to convince the end customer, and assurance that a registered deal will not be taken by another installer. The portal must meet those three needs before anything else.
| Module | Main use | Share of budget | Indicative 2026 range |
|---|---|---|---|
| Partner accounts and tiers (Silver, Gold, Platinum) | Access by status | 10 % | 6,000 to 14,000 USD |
| Tiered price lists and project discounts | Net prices, product sheets | 20 % | 12,000 to 28,000 USD |
| Marketing library (datasheets, visuals, videos) | Co-branded assets | 12 % | 7,000 to 17,000 USD |
| Deal registration and deal protection | Avoid conflicts between resellers | 20 % | 12,000 to 28,000 USD |
| Orders, quotes and delivery tracking | Reseller self-service | 18 % | 11,000 to 25,000 USD |
| Support: RMA tickets, warranties, serial numbers | After-sales traceability | 12 % | 7,000 to 17,000 USD |
| ERP and CRM connectors | Prices, stock, customer accounts | 8 % | 5,000 to 11,000 USD |
Deal registration is often the most profitable module. An installer registers a project (kW size, customer, date), the manufacturer approves it and reserves a project discount for 90 days. This reduces price wars between resellers in the same territory.
Custom build or off-the-shelf PRM: 3-year cost
The estimates below assume 120 active partners with 2 to 3 users each.
| Criterion | Off-the-shelf PRM | Custom portal |
|---|---|---|
| Setup and configuration | 15,000 to 40,000 USD | 60,000 to 140,000 USD |
| Annual licence | 40 to 100 USD per partner, so 4,800 to 12,000 USD | None |
| Maintenance and hosting per year | Partly included | 9,000 to 20,000 USD |
| Total cost over 3 years | 29,400 to 76,000 USD | 87,000 to 200,000 USD |
| Complex price lists (projects, volumes, territories) | Often limited | No limit |
| Manufacturing ERP integration | Generic connectors | Built on your tables and rules |
| Brand experience | Vendor interface | Fully on brand |
At 120 partners, the off-the-shelf PRM stays cheaper over 3 years. Custom takes the lead in two cases: when the network grows beyond 300 to 400 partners, or when deal registration and project discounts are too specific for a standard tool and the team ends up managing them in Excel on the side.
For a tighter budget, Kolonell builds this kind of portal from Dakar: 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) for a medium-complexity portal, 7,000,000 to 15,000,000 FCFA and up (10,670 to 22,870 EUR) with ERP connectors and advanced deal registration, with maintenance from 35,000 to 120,000 FCFA per month.
Launching the portal without losing the network
A portal resellers never open is worthless. Three rules improve adoption. Reserve a portal-only benefit, for example 2 % off orders placed online. Open first to 15 to 20 pilot installers for 4 weeks. Track the share of active partners each month, aiming for 70 % at 6 months.
Mini case study
Illustrative scenario: Michael, VP of channel sales at a New York manufacturer of inverters and racking systems, manages 120 installers. His 3 inside sales reps spend about 25 hours a week sending prices, datasheets and order confirmations.

Chosen project: 95,000 USD, maintenance of 1,200 USD per month, so 14,400 USD a year.
Estimated gains: 15 hours a week freed over 46 weeks, so 690 hours, valued at 55 USD an hour, so 37,950 USD a year. If deal registration prevents 4 deals lost to reseller conflicts, at 10,000 USD of gross margin each, add 40,000 USD. Net gain: 63,550 USD a year, for a payback of about 18 months.
FAQ
How many partner tiers should we plan?
Three tiers are enough for most networks, with annual revenue thresholds such as 75,000, 250,000 and 600,000 USD. Each tier unlocks an extra 3 to 8 points of discount.
Can the portal show real-time stock?
Yes, through an ERP connector that syncs stock every 15 minutes or live. Allow 5,000 to 11,000 USD depending on the ERP.
Can it handle warranties and after-sales?
Yes, the reseller enters the serial number, the fault and photos. Average warranty claim handling often drops from 10 days to 3 days.
Does the portal work from a phone on a job site?
Yes, a responsive web app is enough to check prices and datasheets. Over 50 % of installer sessions happen on mobile.
How long from decision to pilot launch?
Allow 12 to 16 weeks of project work, including 2 weeks to scope the price lists, then a 4-week pilot before opening to the whole network.
