What is the best tech stack for an MSP or IT services company in 2027?

Direct Answer

The best tech stack for an MSP or IT services company in 2027 is built on a tight dual spine: a PSA for the business (tickets, time, billing, contracts) plus an RMM for the machines you manage (monitoring, patching, automation), wired into IT documentation, secure remote access, BCDR backup, and an EDR-led security layer.

For most shops that means ConnectWise PSA + ConnectWise Automate or Autotask + Datto RMM (the Kaseya stack) at scale, or Syncro / Atera as combined PSA+RMM for solo and small MSPs. Wrap it with Hudu or IT Glue for documentation, ScreenConnect or Splashtop for remote control, Datto or Cove for backup, and Huntress plus SentinelOne for endpoint security.

Buy from Pax8 so cloud licensing and billing reconcile automatically.

Why the MSP / IT Services Tech Stack Works Differently

An MSP tech stack is not a smaller version of an enterprise IT stack. It is a manufacturing line for recurring service delivery, and four mechanics make it behave unlike any other industry's tooling.

1. PSA + RMM is the dual spine, not a single CRM. Most industries center on one system of record. An MSP runs on two that must stay in lockstep: the PSA (professional services automation) is the business operating system handling tickets, time tracking, contracts, and invoicing, while the RMM (remote monitoring and management) is the technical nervous system that watches endpoints, pushes patches, and runs automation. When an RMM alert fires, it should open a PSA ticket; when a tech closes that ticket, the logged time should flow to billing. If those two systems do not talk cleanly, technicians double-enter everything and your effective hourly cost balloons.

1. Recurring MRR economics and per-seat billing govern every purchase. MSPs sell monthly recurring revenue priced per seat, per endpoint, or per user. That means your tool costs are also per-seat, and the spread between what you bill a client per seat and what your stack costs you per seat is your gross margin. A new tool is only justified if it either shrinks the labor hours behind a flat-rate contract or becomes a line item you re-bill. This is why mature MSPs obsess over which tools are "cost of doing business" versus "billable products" passed through to the client.

1. Documentation is the intellectual property of the business. For a law firm the IP is its case files; for an MSP it is the documented knowledge of every client environment — passwords, network diagrams, configurations, SOPs, and the tribal knowledge in senior techs' heads. A documentation platform like Hudu or IT Glue is not optional overhead; it is the asset that lets a junior tech resolve a ticket without escalation, lets you onboard new hires quickly, and drives the enterprise value of the firm if you ever sell it. MSPs with weak documentation are held hostage by their most senior engineer.

1. The MSP is its own best and worst customer, and the security stack sits on a stack. You run your own internal IT on the same tools you sell, so you are simultaneously vendor and client. That is a strength — you dogfood everything — but it also means a compromise of your RMM or remote-access tool is a compromise of every client you manage. The 2021 Kaseya and ConnectWise supply-chain incidents proved this. So the security layer is "stack-on-stack": you harden the tools that manage other people's machines (MFA everywhere, conditional access, privileged-access management) before you ever sell a security product downstream.

The Core Stack, Layer by Layer

Each layer below names the best-fit product, an honest reason, a rough price, and one or two real alternates. Skip layers a solo break-fix shop genuinely does not need yet.

PSA / Professional Services Automation — ConnectWise PSA (alternate: Autotask PSA, HaloPSA). The business operating system: tickets, time entry, contracts, agreements, invoicing, and reporting. ConnectWise PSA is the deepest and most integrated platform for mid-to-large MSPs, running roughly $45-$75 per technician per month.

Autotask PSA (now part of the Datto/Kaseya family) is the strongest direct competitor and pairs natively with Datto RMM. HaloPSA has won fans for a modern interface and flatter pricing around $50/agent/month. Solo shops should not buy a standalone PSA at all — see Syncro/Atera below.

RMM / Remote Monitoring and Management — NinjaOne (alternate: ConnectWise Automate, Datto RMM). The technical spine: agent-based monitoring, patch management, scripting, and automated remediation across every managed endpoint. NinjaOne has become the modern favorite for its clean UI, fast deployment, and roughly $3-$5 per endpoint per month pricing.

ConnectWise Automate is the powerhouse for shops already on ConnectWise PSA. Datto RMM and Kaseya VSA anchor the Kaseya stack. Pricing typically runs per managed device.

Combined PSA + RMM for small MSPs — Syncro (alternate: Atera). This is the all-in-one shortcut. Syncro bundles PSA and RMM in one platform at a flat per-technician price (around $139/tech/month, unlimited endpoints), which is dramatically cheaper for a 1-5 person shop than stitching ConnectWise to Automate.

Atera uses a similar per-technician model and bundles RMM, PSA, and remote access. Solo and break-fix operators should start here and only graduate to the split ConnectWise or Datto-Kaseya stacks when seat count and complexity justify it.

IT Documentation — Hudu (alternate: IT Glue). The IP layer. Hudu is the modern, fast-growing documentation platform with integrated password management and tight RMM/PSA links, often around $40+/user/month. IT Glue is the established incumbent (also Kaseya-owned) with deep integrations and a larger template library.

Either one becomes the single source of truth for client environments. ConnectWise also bundles documentation natively for shops staying all-in on that platform.

Secure Remote Access — ConnectWise ScreenConnect (alternate: Splashtop, TeamViewer). How techs actually touch the machine. ScreenConnect (formerly ConnectWise Control) is fast, scriptable, and integrates with the ConnectWise stack at roughly $40-$135/month per technician depending on tier.

Splashtop is the value pick with strong performance and per-tech pricing many MSPs prefer. TeamViewer remains common but pricier. Lock all remote access behind MFA — it is the single most attacked tool in the MSP stack.

Backup / BCDR — Datto (alternate: Cove, Veeam, Acronis). Business continuity and disaster recovery is a core billable product, not just internal hygiene. Datto (Kaseya) offers image-based backup with instant local and cloud virtualization, sold per protected device or per terabyte.

Cove Data Protection is the lighter, cloud-first, no-appliance option that has won cost-conscious MSPs. Veeam and Acronis cover broader workloads and Microsoft 365/Google Workspace SaaS backup. Charge for this — it is one of the clearest re-billable layers.

Endpoint Security / EDR — SentinelOne + Huntress (alternate: CrowdStrike, Bitdefender). The downstream security product and your own protection. SentinelOne delivers autonomous EDR with rollback, priced per endpoint per month. Huntress has become near-mandatory in the MSP world as a managed detection layer that catches what the EDR misses and includes 24/7 SOC analysts — designed specifically for MSP economics.

CrowdStrike is the enterprise-grade alternate; Bitdefender is the value EDR many RMMs bundle. Most MSPs run an EDR plus Huntress as a complementary pair.

Email Security — Proofpoint (alternate: Microsoft Defender for Office 365, Mailprotector). Email is still the top attack vector. Proofpoint leads enterprise email security; Microsoft Defender for Office 365 is the natural fit when clients already live in Microsoft 365; Mailprotector is a popular MSP-friendly mid-market option.

Bill this per mailbox.

Security Awareness Training — KnowBe4. Phishing simulation and end-user training, sold per seat and re-billed to clients. KnowBe4 is the category default and pairs naturally with email security to close the human gap. A clear billable add-on with strong margin.

Quoting / CPQ and Procurement — ConnectWise Sell + Pax8 (alternate: Quoter). How you turn scoping into revenue. ConnectWise Sell builds quotes that flow into PSA agreements; Quoter is the lighter standalone CPQ many smaller MSPs prefer. Pax8 is the cloud distribution marketplace where you buy and provision Microsoft 365, security, and dozens of other SKUs — its billing reconciliation against your PSA is what keeps per-seat margin from leaking.

Accounting — QuickBooks Online. The financial back office. QuickBooks Online integrates with every major PSA, syncing invoices and expenses so you are not re-keying financials. Established MSPs may move to a mid-market ERP, but QuickBooks covers the vast majority.

CRM / Sales — HubSpot (alternate: ConnectWise CRM). New-logo pipeline lives separately from service delivery. HubSpot is the common choice for MSP marketing and sales pipeline; shops standardized on ConnectWise often use its built-in CRM to keep prospects and clients in one platform. A solo break-fix shop can defer this layer entirely.

Real Operators & What They Run

• A solo break-fix shop (1 tech). Runs Atera or Syncro as the entire stack — PSA, RMM, and remote access in one flat per-tech subscription — plus Bitdefender bundled through the RMM and QuickBooks for invoicing. No standalone documentation or CRM yet. The whole stack costs a few hundred dollars a month, and that is the point: the all-in-one keeps overhead near zero until billable seats justify more.

• A growing 8-person MSP. Has graduated to ConnectWise PSA + NinjaOne RMM, added Hudu for documentation, ScreenConnect for remote access, Cove for backup, and the SentinelOne + Huntress security pair. Buys all Microsoft 365 and security licensing through Pax8 so per-seat billing reconciles. This is the canonical mid-stage MSP stack.

• An established 40-person MSP / MSSP. Runs the full ConnectWise platform — PSA, Automate RMM, Sell for quoting, and native documentation — or the equivalent Autotask + Datto RMM + IT Glue Kaseya stack. Layers CrowdStrike or SentinelOne EDR, Huntress managed detection, Proofpoint email security, and KnowBe4 training, then sells that same security stack as a managed-security product line.

• A Microsoft-centric IT services firm. Standardizes everything on Microsoft 365 and Defender for Office 365, uses NinjaOne for cross-platform RMM, Hudu for docs, and procures licensing through Pax8. The bet is that aligning with the client's existing Microsoft tenant reduces friction and makes security upsells obvious.

• A backup-and-continuity-led shop. Builds the practice around Datto BCDR as the headline product, with Autotask as the PSA (same Kaseya family for tight integration), Datto RMM for monitoring, and Veeam added for Microsoft 365 SaaS backup. Continuity is the lead offer; everything else attaches to it.

The pattern across all five: a PSA running the business, an RMM running the fleet, a documentation system holding the IP, secure remote access, real BCDR, and an EDR-plus-managed-detection security pair — sized up or down by seat count, never skipped at the top.

Integration Architecture

The architecture goal is one event flowing cleanly across systems with zero double entry. An RMM alert opens a PSA ticket; the tech connects through remote access and pulls credentials from the documentation vault; logged time posts to the PSA agreement; the PSA invoices and reconciles cloud SKUs against the Pax8 marketplace; QuickBooks records the financials.

The security tools feed alerts back into the PSA so threats become tracked, billable work.

Every arrow that does not exist becomes a person retyping data. The single most valuable integration to get right is the RMM-to-PSA ticket sync; the second is Pax8-to-PSA billing reconciliation, because that is where per-seat margin quietly leaks.

Failure Modes

1. Buying the enterprise stack before you have the seats. A 3-tech shop on full ConnectWise PSA + Automate is paying for and administering a platform sized for a 30-tech firm. The complexity tax — configuration, training, maintenance — exceeds the benefit. Start on Syncro or Atera and graduate deliberately.

1. PSA and RMM that do not talk. Running two best-of-breed tools with no integration means every alert is hand-entered as a ticket and every closed ticket is hand-entered as billable time. The labor leak destroys margin silently. Either buy an integrated stack or invest real effort in the connector before scaling endpoints.

1. Treating documentation as optional. Skipping Hudu or IT Glue feels like a cost saving until your senior engineer takes a vacation and ticket resolution stalls because nobody else knows the client's network. Undocumented MSPs are unsellable and fragile. Document from day one, even if lightly.

1. Selling security you have not applied to yourself. Pitching EDR and MFA to clients while your own RMM and remote-access tools sit behind a single shared password is the stack-on-stack trap. A breach of your management tools cascades to every client. Harden internal access first, then sell the product.

Budget & Sizing

Solo / break-fix (1-2 techs, ~$300-$900/month). All-in-one Syncro or Atera covering PSA, RMM, and remote access; a bundled EDR like Bitdefender; QuickBooks for invoicing. Documentation lives in the all-in-one's notes. No standalone CRM, CPQ, or BCDR appliance yet.

Growing MSP (5-15 techs, ~$2,500-$8,000/month plus per-seat pass-through). Split into ConnectWise PSA + NinjaOne RMM, add Hudu documentation, ScreenConnect remote access, Cove or Datto backup, SentinelOne + Huntress security, KnowBe4 training, and procure licensing through Pax8.

HubSpot for new-logo pipeline. Most of the security and backup spend is re-billed to clients.

Established MSP / MSSP (25+ techs, ~$15,000-$60,000+/month plus pass-through). Full ConnectWise platform or the Autotask + Datto RMM + IT Glue Kaseya stack, ConnectWise Sell CPQ, CrowdStrike or SentinelOne EDR, Huntress managed detection, Proofpoint email security, and a productized managed-security offering.

Heavy Pax8 volume, dedicated billing reconciliation, and often a mid-market ERP replacing QuickBooks.

30/60/90 Day Implementation Plan

• Days 0-30 — Stand up the spine. Choose the PSA+RMM model for your size (all-in-one Syncro/Atera, or ConnectWise/Datto-Kaseya split). Deploy RMM agents to every managed endpoint, configure the core monitoring and patch policies, and verify the RMM-to-PSA ticket sync actually creates and closes tickets. Migrate active clients into the PSA with agreements and billing rules.

• Days 31-60 — Documentation, access, continuity. Roll out Hudu or IT Glue and document every client's network, credentials, and SOPs. Standardize remote access on ScreenConnect or Splashtop behind MFA. Deploy Cove or Datto BCDR and run a test restore for at least one client — an untested backup is not a backup.

• Days 61-90 — Security and margin. Deploy SentinelOne plus Huntress across the fleet, turn on KnowBe4 phishing simulations, and add email security. Move all cloud licensing to Pax8 and reconcile its billing against your PSA agreements so per-seat margin stops leaking. Review the first full month of integrated reporting and tighten the gaps.

FAQ

Should a small MSP use an all-in-one like Syncro or a split ConnectWise stack? Start all-in-one. For 1-5 technicians, Syncro or Atera bundles PSA, RMM, and remote access at a flat per-tech price that is far cheaper and simpler than stitching ConnectWise PSA to Automate.

Graduate to the split stack when seat count, automation depth, or client complexity makes the integrated platform's ceiling worth the added cost.

What is the difference between PSA and RMM, and do I need both? The PSA runs your business — tickets, time, contracts, invoicing — while the RMM runs the machines you manage — monitoring, patching, automation. They serve different jobs and yes, you need both, though small shops get them bundled in one product.

The integration between them is where your operating margin is made or lost.

Is Pax8 worth it, or should I buy Microsoft 365 licenses directly? For an MSP managing multiple clients, Pax8 is worth it. The marketplace centralizes provisioning across Microsoft 365, security, and dozens of vendors, and its billing reconciliation against your PSA prevents the per-seat license leak that quietly erodes margin when you track licenses by hand.

Why run both an EDR and Huntress instead of just one? SentinelOne or CrowdStrike is the autonomous prevention and response layer; Huntress is a managed detection layer with a 24/7 SOC that catches persistence and post-exploitation activity the EDR misses, built for MSP economics.

Most mature MSPs run them as a complementary pair rather than betting on a single product.

Which backup tool should an MSP standardize on? Datto for image-based BCDR with instant virtualization, or Cove if you want a lighter, cloud-first option with no local appliance. Add Veeam or Acronis for Microsoft 365 and Google Workspace SaaS backup. Whatever you choose, run a test restore before you trust it — and bill it as a product.

How much of the MSP stack should be re-billed to clients versus absorbed? Backup, EDR, email security, and security training are clear billable products with margin. PSA, RMM, documentation, and remote access are usually cost of doing business absorbed into your flat-rate or per-seat price.

The discipline is making sure every absorbed tool reduces labor hours faster than it adds cost.
