The MSP tax

MSP tool sprawl: the hidden cost of glue code.

Most MSP stacks split RMM, PSA, billing, documentation and the customer side across separate vendors, wired together with brittle integrations. The work flows through every tool; the data and the bill do not. This is what it costs, and how to fix it.

The shape of a typical MSP stack is four to six vendors deep: an RMM, a separate PSA, a separate billing or accounting bridge, a separate documentation tool, a Zapier or Make subscription holding it together, and a quote-tool sitting off to one side. Each one bills separately. Each one releases on its own cadence. Each one breaks on its own schedule.

The cost is not just the line items on the licence stack. It is the time spent reconciling endpoint counts between the RMM and the PSA. It is the missed invoice when the integration drops a payload at 2am. It is the support ticket that bounces between three vendors all blaming each other. It is the quarterly renewal call with each one.

What it actually costs

Three taxes you pay for tool sprawl

Licence tax

Four to six SKUs, each with its own per-endpoint or per-tech meter. Growth gets taxed twice: once on the RMM contract and again on the PSA contract.

Glue-code tax

Every cross-tool flow needs a webhook or a Zapier scenario nobody owns. When the API changes shape, the flow drops silently. Usually at month-end.

Reconciliation tax

RMM says 412 endpoints. PSA says 408 billable seats. Spreadsheet says 415. Someone burns an hour every billing run reconciling what should be one number.

The alternative

One platform, one data model

OpsMerge folds the RMM, the PSA and the billing engine onto one platform. The glue code disappears because the parts share one database.

Unified RMM

One cross-OS agent, one asset register, one event bus. The agent that reports CPU is the row your invoice line counts.

Unified PSA

Tickets, SLAs, time tracking, quotes and a client portal. Same database as the RMM. Tickets point at the same assets your agents populate.

Unified billing

Recurring contracts count assets off the live fleet, push to QuickBooks Online, void with full reversal. No spreadsheet in the middle.

Unified automation

Scripts at the endpoint, ticket workflows in the PSA, recurring billing actions. One job runner, one event bus, one set of logs.

Flat per-MSP pricing

Not per endpoint. Not per technician. Onboard a new client and the bill stays put. GBP, monthly or annual, on the page at GA.

Honest comparisons

Where each incumbent wins, where they do not, and what migration looks like. No marketing-by-disparagement.

Tool sprawl questions

What MSPs ask before consolidating

  • Why is MSP tool sprawl a problem?
    Each tool charges separately, releases on its own cadence, and breaks on its own schedule. The work flows through every tool, but the data and the bill do not. You end up reconciling endpoint counts between the RMM and the PSA every month, chasing the integration that dropped a payload at 2am, and paying a Zapier subscription nobody owns.
  • How much does tool sprawl actually cost?
    There are three taxes. Licence tax: four to six SKUs each with their own meter, and growth gets taxed twice. Glue-code tax: every cross-tool flow needs a webhook nobody owns. Reconciliation tax: an hour every billing run reconciling what should be one number.
  • Can I consolidate gradually?
    Yes. Most beta MSPs start by pointing OpsMerge at one or two functions (typically RMM and ticketing), run them in parallel with the existing stack for a window, then phase out the incumbents as confidence grows. We do not require a big-bang cut-over.
  • Does consolidating mean losing best-of-breed features?
    Some, honestly. We are not a HaloPSA-equivalent on every ITIL ceremony and we do not have the marketplace breadth of NinjaOne. The trade-off is one platform, one bill, one place to look when something breaks. The /compare pages name where we are honest about each gap.
  • What if a feature I rely on is missing?
    Tell us on the beta application. We track aggregate demand and prioritise from there. We would rather hear the gap before you sign up than a month into onboarding.
