Just Use Wave Pro for Agency Invoicing

Your 3–6 person agency is invoicing 30 clients a month, and FreshBooks is about to hand you a bill you didn’t plan for. Premium at $70/month base. Add three team seats at $11 each: $103/month minimum, before a single transaction clears. Wave Pro charges $19/month flat. No per-seat fees. No client cap. Unlimited invoices. For agencies that already run a project-management tool and don’t need FreshBooks’ profitability reports, that’s $84/month back in your pocket for nothing you’ll miss.

Just use Wave Pro.

Why Wave Pro is the pick

Wave Pro costs $19/month. That’s the entire bill. No per-seat add-ons, no client-count tiers, no forced upgrade when your roster crosses an arbitrary threshold. For a 3–6 person agency invoicing 20–50 clients monthly, the math is immediate and irreversible.

The features agencies actually need are all there:

• Automatic bank feeds via Plaid — transactions import daily without manual CSV uploads
• Automated payment reminders — configurable before and after due date, across all client invoices simultaneously
• Unlimited billable clients — no cap on either plan; no upgrade cliff at 50 clients
• Multi-user access — Pro adds the ability to add additional team members (Admin, Editor, or Viewer roles); this is not billed per-seat
• Recurring invoices — set it up once per retainer client and stop touching it
• Double-entry accounting — books stay clean without a separate bookkeeping tool

The Starter plan (free) is not the right pick for agencies. Automatic bank transaction import and multi-user access both sit behind the $19/month Pro paywall as of June 2026. With 20–50 active client invoices in flight, manual bank reconciliation and absent team access erases the cost advantage immediately. Pay the $19.

What onboarding to Wave Pro looks like in practice: Connect your business bank account via Plaid on day one — feeds are live within minutes. Upload your logo, set your invoice color and footer, then create a client record for each active account. Build one recurring invoice per retainer client, configure payment reminders (we recommend three: 7 days before due, on the due date, and 5 days after), then turn the system loose. Most agencies are fully operational within two hours.

One hard limit: Wave stopped accepting new sign-ups outside the US and Canada in November 2020. If your agency is based elsewhere, this pick doesn’t apply. Go to FreshBooks Premium or Xero.

The payment-processing math you need to see

Subscription cost is not total cost. Wave’s card-processing fees are higher than FreshBooks’, and at sufficient card volume, that gap closes the subscription advantage.

Here’s the structure: Wave Pro charges 2.9% + $0.60 per card transaction (Visa/Mastercard/Discover) after the first 10 monthly transactions, which waive the $0.60 flat fee. FreshBooks charges 2.9% + $0.30 per card transaction, no waiver mechanics.

Run the numbers on a 4-person agency processing $5,000/month in card payments across roughly 20 invoices:

• Wave Pro: $19 base + (2.9% × $5,000) + ($0.60 × 10 excess transactions) = $19 + $145 + $6 = ~$170/month
• FreshBooks Premium: $103 base + (2.9% × $5,000) + ($0.30 × 20 transactions) = $103 + $145 + $6 = ~$254/month

Wave wins by $84/month at $5,000 card volume. Now run it at $15,000/month across 30 invoices:

• Wave Pro: $19 + $435 + ($0.60 × 20 excess) = $19 + $435 + $12 = ~$466/month
• FreshBooks Premium: $103 + $435 + ($0.30 × 30) = $103 + $435 + $9 = ~$547/month

Wave still wins by $81/month at $15,000 card volume. The flat-fee difference ($0.30 vs. $0.60) matters more at high invoice count than high invoice value — agencies sending many smaller invoices feel Wave’s per-transaction cost more than agencies sending a few large retainer invoices. If your agency processes 50+ card transactions per month, run your own numbers. For the majority of 3–6 person service agencies, Wave Pro’s total cost remains lower than FreshBooks Premium’s.

ACH is 1% with a $1 minimum on Wave. If your clients pay by ACH, the per-transaction math disappears entirely and Wave’s $84/month subscription advantage is pure savings.

Why not FreshBooks Premium

FreshBooks is a genuinely good invoicing and bookkeeping tool. Support quality is real — G2 rates it 9.2/10 and reviewers consistently describe reaching a helpful agent within minutes. Bank feed reliability is better than Wave’s. The UI is polished.

But for a 3–6 person agency, the pricing structure punishes you for having a team.

The canonical example: a 4-person agency on FreshBooks Premium pays $70/month base plus $33/month for three additional seats — $103/month before a single transaction. FreshBooks Plus ($43/month) would save $27, but Plus caps at 50 billable clients. An agency invoicing 20–50 clients is one new account away from a forced upgrade at any point. Wave has no equivalent ceiling on any plan.

The features driving the Premium price — project-profitability tracking, accounts payable management, customizable email templates — are only valuable if you’re using FreshBooks as a substitute for a dedicated project-management tool. If your agency runs Asana, Linear, or Monday.com for project tracking, FreshBooks’ profitability module adds nothing at 5x Wave Pro’s subscription cost.

The one scenario where FreshBooks Premium beats Wave Pro: your agency doesn’t use a separate project-management tool, actively uses FreshBooks’ project-profitability reports to track margin by engagement, and needs accounts payable management in the same system. That’s a specific operational setup, not a general one.

Why not the rest

QuickBooks Online — QuickBooks is accounting software that happens to do invoicing, not the reverse. The learning curve, configuration overhead, and pricing (starting at $35/month and climbing fast with add-ons) make it the wrong tool for a small agency that needs clean client invoicing. If your accountant requires QuickBooks for year-end, use it for books only and invoice through Wave.

Xero — Built for businesses needing multi-currency accounting, inventory, and payroll integrations. A 4-person service agency invoicing 30 clients needs none of that. Xero’s entry plan starts at $20/month but limits you to 20 invoices per month — a hard constraint that rules it out immediately for 20–50 client invoicing volume.

Bonsai — A freelancer tool first. Contracts, proposals, and the client portal are designed for a solo operator managing a handful of clients. Multi-user workflows are an afterthought. An agency invoicing 30+ clients hits Bonsai’s limitations fast. Note: Bonsai was acquired by Zoom in December 2025; platform integration is pending and the roadmap is unclear, which adds exit risk for new signups.

Zoho Books — More features than Wave Pro on paper, but the configuration overhead is disproportionate for a small agency that needs invoices out the door. The feature depth that makes Zoho attractive for mid-market companies is friction for a 4-person team.

When to revisit this pick

Wave Pro holds up well through 50 active clients. Two specific growth signals should prompt a reassessment.

Signal one: your team crosses 6 people and needs granular permissions. Wave Pro’s user roles — Admin, Editor, Viewer — cannot be customized, and there are no audit logs or approval workflows for invoices. At 7+ team members with differentiated access needs, Wave’s permission model becomes a liability. FreshBooks Premium’s more structured multi-user controls justify the cost increase at that point.

Signal two: you exceed 50 active clients AND need built-in project accounting. If your agency grows past 50 clients and starts needing margin tracking by engagement — not just clean invoicing — Wave has no project costing layer at all. FreshBooks Premium’s project-profitability module becomes relevant when you’d otherwise buy a separate reporting tool to do the same job. Until you’re at that intersection, the feature gap doesn’t matter.

Wave’s customer support is the weakest part of the stack and worth naming clearly. Free-tier users get no human support. Pro users report multi-day response times on complex issues, and multiple reviews document payment holds and reversals without prior notice. For most agencies these are edge cases, but if your business processes high transaction volume or has a history of payment disputes, the support risk is real.

Until one of those two signals fires: $19/month, no seat fees, no client caps. The math is settled.
