MainWP vs AgenciesWP: What’s the Difference (and Do You Need Both)?

If you searched “MainWP,” you’re probably one of two people: someone comparing tools to manage a bunch of client websites, or someone who already uses MainWP and is now looking for something to handle the business side — clients, invoices, contracts, payments.

This confusion is common, because “agency management” gets used to describe two completely different jobs. Here’s the honest breakdown.

TL;DR

MainWP manages your clients’ websites — bulk updates, backups, uptime monitoring, and security across many WordPress installs from one dashboard. AgenciesWP manages your business — clients, projects, time tracking, contracts, Stripe invoicing, and a branded client portal. They solve different problems and most agencies that use MainWP will still need something like AgenciesWP for the operations side. They’re not competitors — they’re two tools that sit next to each other in your stack.

What Is MainWP?

MainWP is a WordPress plugin built for maintaining many client websites at once. Instead of logging into each client’s /wp-admin separately, you connect their sites to one central MainWP dashboard and manage them in bulk. Its core job is site maintenance, typically covering:

• Bulk plugin, theme, and core updates across all connected sites
• Automated backups
• Uptime and security monitoring
• Basic client site reporting

If your biggest headache is “I have 40 client sites and updating them one by one takes all day,” MainWP-style tools solve exactly that.

What MainWP Doesn’t Do

MainWP is a site management tool, not a business management tool. It has no built-in way to:

• Track which client owes you money
• Send an invoice or accept a Stripe payment
• Log billable hours against a project budget
• Get a client to formally approve finished work
• Send a contract for an e-signature
• Give a client a branded portal to check project status

That’s not a criticism of MainWP — it was never built to do those things. It’s a different category entirely.

MainWP vs AgenciesWP: Side by Side

Do You Need Both?

If you run a WordPress agency or freelance business with multiple clients, there’s a reasonable chance you need both, because they cover opposite ends of the job:

• MainWP (or a similar tool) keeps client sites updated, backed up, and secure.
• AgenciesWP keeps client relationships organized — who owes you money, what’s the project status, has the contract been signed, has the client approved the latest milestone.

Using them together is common: MainWP runs quietly in the background maintaining the technical side, while AgenciesWP is the dashboard you and your clients actually interact with day to day.

If You’re Looking for a MainWP Alternative for the Business Side

Some people land on “MainWP” while actually searching for something to replace a stack of tools — a project manager, a time tracker, an invoicing app, and a client portal. If that’s you, MainWP was never going to solve it, because that’s not what it does.

AgenciesWP is built specifically for that gap:

• Client management — unique Client IDs, magic-link logins, per-client revenue tracking
• Project management — fixed-price or hourly, milestones, status flow, visual timelines
• Time tracking — per-staff rates, live budget accrual, one-click import into invoices
• Stripe invoicing — 5 line-item types, live client balance, one-click client payments
• Contracts & e-signatures — rich-text contracts with a full signing audit log
• White-label client portal — one shortcode, 8 branded sections, no WordPress account needed for clients

It replaces the typical $1,344/year stack of Bonsai, FreshBooks, Toggl, DocuSign, and SuiteDash with one self-hosted plugin starting at $79/year.

Frequently Asked Questions

Is MainWP free? MainWP has a free core plugin with paid extensions for advanced features like premium backups and client reporting.

Can I use MainWP and AgenciesWP on the same sites? Yes. They don’t overlap in functionality — MainWP manages the technical maintenance of client sites, AgenciesWP manages your business operations and client relationships. Many agencies run both.

Is there a tool that does what MainWP AND AgenciesWP do together? Not really, and that’s by design — site maintenance and business/client management are different enough jobs that combining them into one tool tends to make both halves worse. Using a dedicated tool for each side works better in practice.

Which one should I set up first? If you’re just starting out with client work, set up AgenciesWP first — clients, projects, and invoicing are what get you paid. Add a site-maintenance tool like MainWP once you’re managing enough sites that manual updates become the bottleneck.
