What it is

Definition & scope

Outsourced billing operations for NetSapiens® providers — invoice runs, rating fixes, dispute handling, and recurring billing workflows handled by engineers under your brand. Billing is where MSPs and resellers lose the most margin to operational drag: missed rate updates, unmapped DIDs, manual usage reconciliation, customer billing disputes that need carrier-side investigation. This service runs the billing cycle as an operational function so your team stops spending half a week per month on it.

What's included

Scope of work covered.

Every item below is delivered as part of the engagement — no add-ons, no surprise line items.

Monthly invoice cycle

Run, validate, and prepare invoices in your billing system (Datagate, BillSmart, NetSapiens® native, or custom).

Rating verification

Pre-run reconciliation between configured rates and actual call records to catch mis-rated calls before invoicing.

DID and number lifecycle

Provisioning, port-in/out billing impact, deactivation cleanup, unbilled-number detection.

Recurring service plan management

Plan changes, mid-cycle proration, add-on activation, contract renewal billing.

Dispute investigation

When a customer disputes a charge, we pull CDRs, trace the rating logic, and prepare a written explanation with supporting data.

Carrier reconciliation

Validate carrier invoices against your billing, flag and dispute discrepancies, document the resolution.

Monthly operations report

Invoice volumes, dispute counts, rating exceptions, plan-change summary.

What's not included

Out of scope.

We're upfront about boundaries so there are no surprises later. These items are either handled by you, a specialized partner, or scoped as a separate engagement.

  • Direct customer billing communication (we prepare the response; you send it under your brand).
  • Tax calculation, filing, or remittance (use a specialized tax compliance service like Avalara or CSI).
  • Credit collections or write-offs (your finance team owns these decisions).
  • Custom development on your billing system (separate engagement if needed).

Onboarding

How we get started.

A predictable onboarding designed to plug into your stack with minimum disruption.

Step 1

Billing system access

User accounts in your billing platform with appropriate permissions, plus a read-only view of your NetSapiens® tenant for rating verification.

Step 2

Rate book documentation

We capture every rate, plan, add-on, override, and special-case in a versioned reference document.

Step 3

Process documentation

Invoice cycle date, dispute handling workflow, plan-change approval flow, customer-facing communication template.

Step 4

First cycle in parallel

We run alongside your current process for one billing cycle, comparing outputs. After validation, we take primary operation.

Service-level agreement

What we commit to.

Invoice cycle runs to your scheduled date — no exceptions. Rating validation completes 72 hours before invoice send to allow for fixes. Disputes acknowledged within 4 business hours; investigated and written up within 2 business days. Plan changes processed same-business-day. Mid-cycle billing emergencies (incorrect invoice already sent to a major customer, billing system outage, carrier invoice discrepancy at month-end) are treated as critical incidents with the 15-minute response SLA.

FAQ

Common questions about outsourced voip billing support.

Which billing systems do you work in?

Datagate, BillSmart, NetSapiens® native billing, Sycamore, CSG, and custom systems built on the NetSapiens® API. We're tool-flexible — most of the work is operational, and we adapt to whatever you run.

How do you handle disputes?

Customer reports the disputed charge to you. You forward to us. We pull CDRs, trace the rating logic, compare to the contract or plan, and produce a written response with supporting evidence. You review and send to the customer under your branding. Most disputes resolve with the first response.

What about taxes?

We don't calculate, file, or remit taxes — that's specialized regulatory work better handled by Avalara, CSI, SureTax, or your tax department. We do verify that tax line items appear correctly on invoices and that taxable/exempt classification matches your tax provider's logic.

How do you catch rating errors before invoices send?

We run a pre-invoice reconciliation between your configured rates (per plan, per destination, per overflow) and the actual CDRs for the cycle. Calls rated outside the expected range get flagged for human review before invoicing.

How does carrier invoice reconciliation work?

At month-end, your upstream carrier sends an invoice for the minutes and DIDs they billed you. We validate that against your billing system: were all the DIDs you bill customers for actually billed to you? Are there minutes the carrier charged for that your CDRs do not show? Discrepancies become formal disputes back to the carrier.

Can this scale with our customer count?

Yes — billing operations scale linearly with customer count and invoice volume. We size the engagement to the cycle workload, not to seat counts.
