The best billing software for an MSP depends on what you bill. If most of your revenue comes from Microsoft 365, Microsoft Azure and Acronis Cyber Protect Cloud resold through Microsoft CSP, RackNap automates provisioning, usage billing and invoicing on one platform. If you mostly bill labor and fixed-fee agreements, a PSA such as ConnectWise PSA, Autotask PSA or HaloPSA is a better fit.
84% of organizations say managing cloud spend is a top challenge, according to Flexera’s 2025 State of the Cloud Report. For MSPs managing multiple cloud subscriptions and usage-based services, choosing the right billing software is essential.
RackNap is a managed services billing software built for cloud resale. It connects to Microsoft 365, Microsoft Azure, AWS, Google Workspace, and Acronis, then runs recurring, usage-based, and hybrid billing automatically.
What Is MSP Billing Software?
MSP billing software turns licenses, cloud usage, devices and labor hours into accurate recurring invoices. Good MSP invoicing software removes the spreadsheet step between vendor bills and client bills. That matters because cloud resale changes every month: seats are added mid-cycle, Azure usage moves daily, and backup storage grows. Manual billing misses those changes, and the missed charges come out of your margin.
Most MSP software with billing falls into three groups:
- PSA tools (ConnectWise PSA, Autotask PSA, HaloPSA, Kaseya BMS, SuperOps, Syncro): bill contracts, tickets and time.
- Cloud billing platforms (RackNap, Pax8): provision and bill Microsoft CSP, Azure, Acronis and other subscriptions.
- Specialist tools (Gradient MSP, Rev.io): reconcile vendor usage or rate telecom usage.
What Is the Best Billing Software for an MSP?
There is no single best MSP billing software in 2026. Cloud-heavy MSPs get the most from RackNap or Pax8; labor-heavy MSPs get the most from a PSA. Prices are in USD as published or reported in October 2026.
| Tool | Best for | Pricing model (USD) | Microsoft 365 / Azure / Acronis |
| RackNap | MSPs, CSPs and distributors billing cloud at scale | Standard $10K/mo, Enterprise $25K/mo, Premium custom; plus setup and transaction fees (plans) | Native integrations for all three |
| ConnectWise PSA | Established MSPs with complex agreements | Quote-based; reported $25–$35 per user/mo | Acronis integration; Microsoft via distributor |
| Autotask PSA | Kaseya and Datto shops | Quote-based, per user | Via Pax8 sync |
| HaloPSA | Growing MSPs needing flexible contracts | Reported $95–$115 per agent/mo | Via integrations |
| Kaseya BMS | Kaseya VSA users | Reported from $25 per user/mo | Via Pax8 sync |
| SuperOps | Small MSPs wanting PSA + RMM | $149–$179 per technician/mo | Pax8 sync with proration |
| Syncro | Small MSPs wanting per-tech pricing | $129–$179 per user/mo (annual) | Microsoft 365 billing on Team plan |
| Gradient MSP | Catching unbilled licenses | $299–$999/mo by customer count | Microsoft add-on +$199/mo |
| Pax8 | Buying cloud through a distributor | Margin on products bought | Microsoft and Acronis in catalog |
| Rev.io | Voice and telecom MSPs | Quote-based | Usage rating engine |
Two patterns stand out. First, PSA pricing scales with technicians, while RackNap and Gradient MSP pricing scales with the size of your cloud business. Second, PSAs usually rely on Pax8 or a reconciliation add-on to bill Microsoft cloud usage, while RackNap bills Azure consumption and Acronis usage directly.
How Do The 10 Best MSP Billing Software Tools Compare?
Each tool solves a different billing problem, so pick up what you bill most.
1. RackNap

2. ConnectWise PSA
Best for complex agreements. It bills recurring agreements, time and materials, prepaid blocks and products, and syncs to QuickBooks or Xero.
Trade-off: No public pricing.

4. HaloPSA
Best for flexible contracts. HaloPSA covers ticketing, time tracking, contracts, and billing in one tool. Reported pricing falls from $115 per agent/mo. (5–10 agents) to $95 (200+ agents), plus about $4,000 for onboarding. Trade-off: Cloud billing depends on integration.
5. Kaseya BMS
Best for Kaseya VSA users. It covers billing, ticketing and contracts, and Pax8 syncs subscriptions to contracts.
Trade-off: RMM costs extra.
6. SuperOps
Best for small MSPs wanting PSA and RMM together. Pro ($149 per technician/mo.) includes automated billing and invoicing, and Super costs $179. Its Pax8 integration imports subscriptions into client contracts and prorates quantity changes automatically.
Trade-off: Labor billing first, cloud second.
7. Syncro
Best for predictable per-tech pricing. Core ($129 per user/mo., billed annually) includes invoicing, recurring billing, and a branded client portal. Team ($179) adds automated Microsoft 365 license billing.
Trade-off: No native Azure consumption billing.
8. Gradient MSP
Best for catching unbilled licenses. Reconcile matches vendor usage from Pax8, Ingram Micro and TD Synnex to what you bill in Autotask, ConnectWise, HaloPSA, Kaseya BMS or Syncro. Tiers run $299–$999/mo. by customer count.
Trade-off: It does not invoice on its own.
9. Pax8
Best for distributor-led buying. Pax8 offers free integrations with Autotask, ConnectWise, Kaseya, Syncro, SuperOps and RepairShopr that sync subscriptions to contracts or recurring invoices.
Trade-off: You are tied to one distributor.
10. Rev.io
Best for telecom revenue. Rev.io offers a rating engine for usage-based pricing, tax calculation, dunning for failed payments and customer portals.
Trade-off: Priced for larger operators.
Which MSP Billing Software Works with Microsoft 365, Azure and Acronis?
RackNap provisions and bills all three in one billing engine. Pax8 sells all three but relies on your PSA to invoice, while Syncro and SuperOps bill Microsoft 365 mostly through Pax8.
- Microsoft 365 (Microsoft CSP): RackNap provisions licenses, runs auto-renewals and invoices with your other services.
- Microsoft Azure: RackNap captures consumption data automatically and bills it as usage-based or hybrid pricing.
- Acronis Cyber Protect Cloud: RackNap supports per-workload and per-GB pricing, pre-paid billing with usage alerts, and reconciliation reports that keep both panels in sync
If you already run a PSA, you do not have to replace it. A common setup is to keep the PSA for tickets, time and labor agreements, and add RackNap as the cloud billing layer for Microsoft CSP, Azure and Acronis. Clients then get one accurate invoice for cloud services, and your team stops reconciling vendor bills by hand each month.
How Do You Choose MSP Billing Software?
Start from your revenue mix, then test the tool on real invoices.
- Split last quarter’s revenue into labor, agreements, Microsoft 365, Azure, backup and other resale.
- Match the tool to the biggest slice: a PSA for labor; MSP cloud billing software such as RackNap for cloud.
- List must-have integrations: Microsoft CSP, Azure, Acronis, your distributor, your PSA and QuickBooks or Xero.
- Compare pricing models: per-technician pricing grows with headcount; per-customer or platform pricing grows with clients.
- Run one month of invoices in a demo and check proration, usage and taxes against your current bills before you switch.
If cloud resale is a small share of your revenue, a PSA with a Pax8 sync is usually enough. If Microsoft CSP, Azure and Acronis drive most of your growth, look at dedicated MSP cloud billing software.
