The short answer
The best agency software stack in 2026 covers seven categories: CRM, project management, time tracking, invoicing, payments, freelance hiring, and communication. No single tool covers all of them. The goal is to pick the right tool per job and minimise the number of places your data lives.
The average agency uses 3-5 separate tools to manage client payments alone (Petl Pay internal research). Running an agency means running a small operations department you never signed up for. Here's what's actually worth using, by category.
CRM and client relationships
HubSpot is the default for agencies that want a free starting point with room to scale. The free CRM is genuinely good. The paid tiers get expensive fast, but if you're running an inbound pipeline it's hard to argue with the breadth of what's included.
Pipedrive is the better pick if your sales process is straightforward and deal-driven. Cleaner interface, less bloat, more focus on moving deals through a pipeline.
Folk is worth watching. Relationship-first rather than pipeline-first. Better for agencies that win through referrals and networks rather than volume outreach.
Project management
Notion has become the agency default. Docs, wikis, databases, project tracking, and client portals in one place. The flexibility is its strength and its weakness. You need to actually build the system.
Asana is more structured. Better if your team needs clear task ownership and deadline visibility without configuring their own setup from scratch.
Linear is worth considering if your agency does any product or engineering work. Built for speed, minimal friction, and genuinely pleasant to use day to day.
Time tracking
Toggl Track is the cleanest option. Browser extension, mobile app, integrates with most project management tools. If you're billing by the hour, this is where to start.
Harvest bundles time tracking with basic invoicing and project reporting. Good if you want fewer tools rather than better ones.
Clockify is free for unlimited users and unlimited time tracking. If you're cost-sensitive and willing to accept a slightly rougher interface, it does the job.
Invoicing
Xero is the UK agency standard. Accountant-friendly, solid bank feeds, good multi-currency support. The right call if you're billing UK clients and want your finance in one place.
FreshBooks suits smaller agencies and solo operators better. Client portal, proposal tools, and invoice tracking in one package. Less powerful than Xero, but faster to get running.
QuickBooks is more common in the US. Fine for international teams, but if you're UK-based, Xero has better local bank integrations.
The limitation all three share: they handle invoicing well, but none of them solve paying multiple contributors from a single client payment. That's a different problem.
Payments
Stripe handles inbound client payments cleanly. Card processing, payment links, invoicing. The standard choice for collecting from clients online.
Wise Business is the go-to for international transfers. Transparent FX rates, multi-currency accounts, and free batch payouts to up to 1,000 recipients. Strong choice if your contributors are spread across countries.
GoCardless is worth adding for recurring client payments via direct debit. Particularly good for UK retainer clients who pay monthly.
Petl Pay is built for a specific problem the others don't address: paying multiple contributors from a single client invoice. One payment comes in from the client, Petl Pay splits and settles to every contributor across fiat and stablecoin rails automatically. Built for agencies paying subcontractors and freelancers across borders. If that's your setup, it fills a gap that Wise and Xero can't close.
Freelance hiring
Contra has emerged as the cleanest platform for hiring independent professionals. Zero platform fees for contractors. Good for design, marketing, and operations roles.
Malt is strong in the UK and EU for finding senior freelancers and specialists. Good talent pool, reasonable rates, and solid vetting.
Toptal if you need pre-vetted engineering or finance talent and can justify the premium. The vetting process is rigorous and the quality floor is high.
Deel if you need compliance infrastructure alongside hiring. Contractor agreements, IP assignment, and local compliance in 100+ countries. More expensive, but it handles the legal layer properly.
Communication and documentation
Slack remains the standard for async team communication. Nothing has meaningfully replaced it for day-to-day team coordination.
Loom for async video, client handoffs, and briefing freelancers. Cuts a significant amount of back-and-forth that would otherwise become a thread.
Notion again for documentation, client wikis, and anything you want to write once and reference indefinitely.
The honest take
No agency runs on one tool. The goal is to pick the right tool for each job and minimise the number of places information lives.
The gap most agencies feel but can't quite name: invoicing tools handle the client side, payroll tools handle employees, but nobody has built for the space in between, where you're collecting from one client and paying five contractors across three countries. That's the problem worth solving in 2026.
Frequently asked questions
What software do most agencies use?
Most agencies use a combination of HubSpot or Pipedrive for CRM, Notion or Asana for project management, Xero for invoicing, Wise or Stripe for payments, and Slack for communication. There's no single dominant stack, but these tools appear consistently across agency setups of all sizes.
What's the best CRM for a small agency?
HubSpot's free CRM is the most common starting point for small agencies. It covers contact management, deal tracking, email logging, and basic reporting without requiring a paid plan. Pipedrive is a better fit if your focus is purely on closing deals rather than managing an inbound funnel.
What's the best invoicing software for UK agencies?
Xero is the standard for UK agencies. It handles multi-currency invoicing, integrates with most UK banks, and is widely used by UK accountants. FreshBooks is a lighter alternative for solo operators or very small teams.
How do agencies pay international freelancers?
Wise Business is the most common solution for international contractor payments. It offers competitive FX rates, multi-currency account balances, and free batch payouts. For agencies managing multiple contributors per project, a payment orchestration platform like Petl Pay handles the split from a single client invoice across different currencies and payment rails.
Do agencies need separate invoicing and payments software?
Often, yes. Invoicing tools like Xero are built around billing clients. Payments tools handle the outbound side, paying contractors, freelancers, and suppliers. The two are separate workflows. Some agencies try to run both through Xero but hit limitations when dealing with multiple payees, international transfers, or split payments from a single project invoice.
What's the best time tracking software for agencies?
Toggl Track is the most widely used option for agencies billing by the hour. It's clean, integrates with most project management tools, and has a reliable browser extension. Harvest is a good alternative if you want basic invoicing bundled in. Clockify is the free option for teams that need unlimited tracking without paying per seat.
