Whether you're switching wholesale suppliers or choosing one for the first time, the provider you pick shapes what you're able to offer, how well-supported you are, and how much margin you actually keep. Here's a practical checklist of what genuinely matters, beyond the headline pricing.
A narrow product range means juggling multiple wholesale relationships to cover what customers actually ask for. Look for a provider covering the full spread — hosted telephony, SIP trunks, business broadband, mobile SIMs, and hardware — from a single supplier and a single bill. Fewer relationships to manage means less admin and fewer places for something to fall through the cracks.
Some wholesalers also sell directly to end customers, which puts them in direct competition with their own resellers — effectively fighting you for the same customer with the advantage of no margin to protect. A genuinely channel-focused provider sells exclusively through partners and never approaches your customers directly.
Some wholesalers are "switchless resellers" — reselling someone else's underlying platform rather than running their own. This usually means a longer chain when something needs fixing: your issue goes to them, then up to whoever actually owns the platform, then back down again. A provider running its own switch can typically diagnose and resolve issues directly, without that extra layer.
Wholesale pricing should leave genuine, sustainable margin once you've set your own customer pricing — not just a token discount off retail rates. Ask for a clear breakdown of wholesale cost per product, and understand whether pricing changes with volume or stays flat regardless of how much business you bring.
Day-to-day account management — provisioning a new customer, changing a call route, pulling a call recording — should be something you can do yourself through a portal, not something that requires raising a support ticket and waiting. A provider without proper self-service tools will slow down every single change your customers ask for.
Particularly when you're new to reselling telecoms, real support and proper onboarding matter more than they might seem at first. Ask what support actually looks like day to day — is there a dedicated account manager, or a generic support queue? How quickly do faults typically get resolved?
