What Questions Should US Businesses Ask When Choosing the Best Managed Services Billing Software?

Introducing: The Decision That Will Dictate Your Operational Future

For a US-based Managed Services Provider (MSP), selecting a new billing platform is one of the most consequential decisions you will make. It’s not just an accounting tool; it’s the central nervous system that connects your service delivery, your client relationships, and your financial health. The wrong choice can lead to operational friction, revenue leakage, and stunted growth, while the right choice can automate complexity, provide strategic insight, and become a true competitive advantage.

Moving beyond feature checklists and sales demos requires asking penetrating, operational questions. This guide outlines the ten essential questions every US MSP should pose to potential vendors to uncover the true capability, fit, and long-term viability of a managed services billing software platform.

Category 1: Integration & Compatibility from the Ecosystem

How deeply are you native integrated with any/ all of our stack's key tools e.g., PSA (Connectwise, Autotask), RMM, and accounting?

The big picture: What even constitutes "integration" can range from a brittle API to a common database. You’ll want to see if time entries from a closed ticket are automatically pulled into an invoice or if its a manual export/import thing. And, as a bare minimum for efficiency reasons – deep, native and pre-built integrations are critical.

- " Is your billing directly built into one central database, or is the billing how you describe as in separate 'syncs' to other sections of your platform?"

That matters: Everyone is talking about data integrity. Integrated platform (as in a real ERP) so your PSA, billing and GL all use the same data. No synchronism delay, no forbidden overlap. A suite of “best-of-breed” tools that syncs may simply create data silos and headaches around reconciliation.

Category 2: Flexible and Automated Billing Models

Can your system accommodate our broad scope of complex billing models under one client account – MRR/contractual, block hours, T&M projects and single sale product, on a single invoice?

Why it matters: Your business is a hybrid. What you need is something that doesn’t force the sad reality of it upon you, making you sign up for multiple accounts or send out manual invoices and reminders in different formats by different mediums based on service type per client.

"Can you briefly get me through your workflow of how do you automate a contract renewal and price increase. "Proration, client notifications and updated recurring invoicing... how does the system manage all of that?"

Why it matters: According to their respective websites, they aim at managing MRR at scale by automating the process. The tool should provide automatic updates/renewals for quotations, apply new rates to future invoices (with proration adjusted accurately if rate changes are mid-period), and record acceptance.

Category 3: US - Group and Compliance, and Security Requirements

"Do you have SOC 2 Type II and can I see your report? What type of data security and role-based access controls do you have configured?

What to watch: You're dealing with sensitive client financial and IT information. SOC 2 is a standard that you can use to validate your vendors’ security, availability and confidentiality controls. You need lock down internal security with strong access control.

US Sales Tax: How does your software manage US sales tax and support reporting for various state requirements?

Why it matters: Sales tax nexus in the US is both complicated and changing. Manual tax computation is a risk. It should automatic tax input for client location/service type, if possible and detailed reporting to assist with filings.

Category 4: Reporting, Viscibility and Scaling

“Outside of simple P&L, what MSP abnormal KPIs do you report on?” (e.g.,MRR/ARR, Churn Rate, Customer Lifetime Value, Technician Utilization).”

Why it matters: You run a subscription business. You want metrics that mirror that model. Generic accounting reports aren’t going to tell you who your most valuable clients are or how well your recurring revenue engine is doing.

"Can I talk to another MSP based in the US at about the same size and type business who has graduated their company with your platform over 3-5 years?"

Why it matters: You have to have proof of scalability! A tool that can handle a five-man MSP might fall on its face with 500 endpoints. It’s great to be able to talk with somebody that has gotten up and is scaling because you see what works, how they handle support, performance and upgrades.

Category 5: Vendor Partnership and The Total Cost

"Tell me what your set-up and onboarding is like? Do we get a dedicated specialist and when can we expect to be up and running?"

The big picture: You cannot DIY a complicated platform. The following implementation and best practices are crucial to adoption, data migration and rapid ROI. Be cautious of vendors who simply give you login credentials.

"What are all the costs, beyond the user subscription fee? (Implementation, training, payment processing fees and options to bypass with premium support tiers/history of future price increases)?"

The bottom line: TCO You need to know how much the Total Cost of Ownership (TCO). There may also be hidden charges for “modules” or support, and transactions that could double your anticipated cost. Request a simple, all-inclusive quote and their historic rate of price increases.
