Why Do So Many Resellers Leave Money on the Table?
Most telecoms resellers set their prices once and move on. You pick a markup, apply it across the board, and hope it works out. But if you’re not regularly checking your margins, you’re almost certainly losing money somewhere.
The good news? You don’t need to raise prices to improve your margins. Better visibility into your costs, smarter bundling, and tighter billing processes can all make a real difference. This post covers five practical ways to get more from the revenue you already have.
Key Takeaways
- Small cost differences per call add up to significant margin loss across thousands of calls a month
- Bundles improve margins when designed around actual customer usage patterns
- Regular profitability reviews catch accounts that are costing you money
- Faster, more accurate billing improves cash flow and reduces disputes
Do You Really Know What Each Service Costs You?
You can’t improve margins if you don’t know your true costs. That sounds obvious. But many resellers underestimate what they’re actually paying, because carrier billing is full of small details that add up.
Where the hidden costs sit
Here are the things that catch resellers out most often:
- Termination rates that vary by destination and time of day. You might know your standard per-minute rate, but do you know the rate for every destination your customers call? International calls, special-rate numbers, and mobile termination all have different costs. If you’re applying a flat markup, some of those calls might be losing you money.
- Access charges. These are the fixed costs your upstream carrier charges you regardless of call volume. They’re easy to overlook when you’re focused on per-minute rates, but they eat into your margins on every call.
- Rounding differences. Your carrier rounds call durations one way. You might be rounding them a different way when you bill your customers. A one-second difference doesn’t sound like much. But across thousands of calls a month, those fractions of a penny add up.
- Rate changes you didn’t notice. Carriers adjust their rates. Sometimes they send a notice. Sometimes the notice gets buried in an email. If you don’t update your billing to match, your margins silently shrink.
From our experience: The single most common margin leak we see from new customers is a mismatch between carrier rounding and customer billing rounding. It’s the kind of thing nobody checks because each individual difference is tiny. But it adds up to real money.
A proper CDR processing and billing platform shows you the exact margin on every call, every customer, and every service. That’s the starting point for everything else in this post.
How Can Smarter Bundles Improve Your Margins?
Bundles are good for your customers and good for your margins. But only if you design them well. A poorly structured bundle can lock you into thin margins. A well-designed one gives your customers better value while improving your bottom line.
Cross-service bundles
Combine voice, data, and other services into a single package. Customers like the simplicity of one bill with one price. You benefit in two ways: higher revenue per customer, and lower churn because they’re buying more from you.
Price the bundle lower than the total of buying each service separately. Your customer feels like they’re getting a deal. You make more overall because they’re taking services they might not have bought individually.
Usage allowances
Include a set amount of usage in each bundle. Here’s where it gets interesting. Most customers won’t use their full allowance. That gap between what they pay for and what they use is your margin.
But be careful. Set the allowance too low and customers feel short-changed. Set it too high and there’s no margin benefit. The sweet spot is just above what most of your customers typically use. You need usage data to find that point, not guesswork.
Review your bundles regularly
Customer usage patterns change. A bundle that worked well a year ago might not be right today. Check your usage reports quarterly. If most customers are nowhere near their limits, you might be giving away more than you need to.
What Is Margin-Based Routing?
If you work with more than one carrier for voice, you have a choice about which carrier handles each call. Most resellers route based on cost: send each call to the cheapest carrier. But that’s not always the best approach.
Margin-based routing looks at the difference between what you pay the carrier and what you charge the customer. If two carriers offer similar quality on a route, you pick the one that gives you the better margin, not just the lower cost.
Where this makes a difference
- Time-of-day routing. Carrier rates often vary by time of day. At peak times, one carrier might be cheaper. Off-peak, another might be better. Routing calls to the right carrier at the right time improves your margin without your customers noticing any difference.
- Destination-specific routing. International and special-rate calls are where margins vary most. A carrier that’s great for UK mobile calls might be expensive for international. Route each call type to the carrier where you make the most.
You don’t need to do this manually. Your billing platform should show you which routes are most profitable. Then it’s just a matter of adjusting your routing tables to match.
Are All Your Customers Actually Profitable?
Not every customer is making you money. Some might be costing you more than they pay. The only way to know is to check.
Customer profitability reviews
Group your customers by revenue, margin, and service type. You might find that your biggest customer by revenue has your thinnest margins, while a smaller account is far more profitable. That’s useful information.
Look for:
- Customers where your costs have risen but your prices haven’t. Carrier rate increases that you didn’t pass on will quietly erode your margins over time.
- Services where your margin has dropped below a minimum threshold. If a particular call type or destination isn’t making money, you need to either adjust the price or accept the loss knowingly.
- High-support customers. Some customers generate far more billing queries and support requests than others. That support time has a cost, even if it doesn’t show up in your margin reports. Factor it in when you’re assessing profitability.
Set a reminder to review this quarterly. It takes minutes when you have good margin reports. It takes hours if you’re doing it from spreadsheets. And most resellers doing it from spreadsheets never get round to it at all.
How Does Billing Efficiency Affect Your Margins?
How you bill matters as much as what you bill. Errors, delays, and disputes all cost money, either directly or through the time they take to sort out.
Accuracy saves money
Every billing error costs time to investigate and fix. It also costs trust. When a customer finds a mistake on their invoice, it takes more than a correction to repair the relationship. Accurate bills mean fewer disputes, fewer credits, and less time spent explaining charges.
Bill faster, get paid faster
The quicker your invoices go out, the quicker you get paid. If your billing cycle takes two weeks after month-end, that’s two weeks of cash flow you’re missing. Automated billing cuts that to a day or two.
Pair that with automated payment collection and you’re not just invoicing faster, you’re collecting faster too. Less time chasing payments means better cash flow and less admin.
Reduce disputes before they happen
Most billing disputes come from unclear charges or unexpected amounts. Clear, itemised invoices with detailed breakdowns stop disputes before they start. A customer portal where people can check their usage in real time helps even more. When customers can see what they’re spending as they go, the invoice at the end of the month holds no surprises.
Where Should You Start?
You don’t need to overhaul everything at once. Pick one area and work on it this month:
- Check your margin reports. If your billing platform shows margin by customer and service type, start there. Find the biggest gaps. Fix those first.
- Pick five customers at random. Compare what you’re charging with what you’re paying the carrier. Look for rounding differences, missed charges, or rates that haven’t been updated.
- Review your bundles. Pull your usage data and check whether your allowances are set in the right place. Are most customers well under their limits? Could you adjust?
- Look at your billing timeline. How many days after month-end do your invoices go out? Every day you shave off is a day sooner you get paid.
Small improvements across many customers add up to a meaningful difference in your bottom line. You don’t need to find one big win. Lots of small ones will do.
Frequently Asked Questions
How often should I review my telecoms reseller margins?
Quarterly is a good starting point. That’s often enough to catch problems before they grow, but not so often that it becomes a burden. If your billing platform shows margin reports in real time, you can check more often without extra effort. The key is to make it a regular habit, not a once-a-year event.
What’s the biggest margin killer for telecoms resellers?
Lack of visibility. If you can’t see your margins at the customer and service level, you can’t manage them. Many resellers only look at total revenue and total cost. That hides the accounts and services where you’re barely breaking even or actively losing money.
Can I improve margins without raising prices?
Yes. Better cost visibility, smarter bundling, tighter billing accuracy, and faster invoicing all improve margins without any price increase. Most resellers find meaningful savings just by fixing the gaps in their current billing, like missed charges, rounding differences, and outdated rates.
What should I look for in a billing platform for margin management?
Look for margin reports by customer, by service, and by call type. You want to see both revenue and cost at every level, not just the totals. Real-time reporting is better than monthly exports. And make sure the platform can show you carrier costs alongside your customer rates, so you can spot mismatches quickly.
