What's the Best Billing Software for Marketing Agencies?

The best billing software for a marketing agency replaces your QuickBooks-plus-spreadsheets stack with recurring subscription invoicing, ACH and card collection, a branded client portal, and per-client margin visibility in one place, rather than a generic accounting tool built for one-off transactions. Look for agency-specific features like automated subscription billing, white-label portals, and wholesale-cost-vs-billed margin tracking, not just a general SMB invoicing app.

Agencies don't sell the same thing twice a year — they bill the same clients every single month, which is exactly what most general billing tools weren't built for. QuickBooks handles bookkeeping but has no native subscription engine or client-facing portal, and generic invoicing apps don't track your wholesale cost against what you charge. Here's what actually separates purpose-built agency billing software from a spreadsheet with better fonts, and where HubWho — a billing platform built specifically for agency recurring revenue — fits into that picture.

Why the answer is what it is

Recurring billing that runs itself

The best tools turn each client agreement into a subscription that generates invoices automatically instead of you re-creating one every month. HubWho is built to do this natively: set the plan once and it invoices on schedule, with proration generated automatically when a client upgrades or downgrades mid-cycle.

Collect via ACH, not just card

Card processing runs roughly 2.9% plus $0.30 per transaction, which adds up fast on high-ticket recurring clients. Look for software that supports ACH bank-link in addition to cards, so auto-drafts cost cents instead of dollars. HubWho does this through Plaid bank-link alongside card and Apple Pay.

Per-client margin, not just revenue

Revenue tells you what you billed; margin tells you what you kept. Worthwhile agency billing software tracks your wholesale cost against what you charge, per client and per service, so you can spot underpriced relationships. HubWho computes this from a wholesale-cost field on each invoice line, on demand when you pull the report rather than a running real-time feed.

A branded portal your clients actually use

If clients still email you asking for their invoice, the portal isn't doing its job. Look for magic-link login (no password to reset or reissue) and a custom domain so the portal reads as part of your agency, not a bolted-on tool. HubWho's client portal supports both, along with payment history and active services in one place.

Real reporting, not a spreadsheet at quarter-end

MRR, churn, accounts-receivable aging, and win/loss numbers should be visible without exporting anything. HubWho surfaces these on a reports tab alongside a five-bucket A/R aging view and a QuickBooks CSV export for when the data still needs to land in your books.

What to look for

  • Confirm it supports recurring/subscription billing, not just one-off invoices
  • Check whether it collects via ACH bank-link, not only card, for high-ticket clients
  • Verify it tracks wholesale cost vs. billed amount per client, not just total revenue
  • Look for a white-label client portal on your own domain with no-password login
  • Ask whether dunning policies are configurable even if automated reminder sending isn't live yet
  • Confirm multi-currency means per-invoice currency selection, not automatic FX conversion, if you bill internationally
  • Check for a QuickBooks or accounting export so you're not double-entering data

Related questions

Can QuickBooks handle agency billing on its own?

QuickBooks is built for general bookkeeping, not agency-specific recurring billing. It has no native subscription engine, branded client portal, or per-client margin tracking, which is why many agencies end up layering a spreadsheet or a dedicated tool on top of it.

Is ACH cheaper than credit card for recurring agency billing?

Yes. Card processing typically runs about 2.9% plus a per-transaction fee, while ACH bank-link transfers cost a small flat fee regardless of invoice size, which matters most on higher-ticket monthly retainers.

Does HubWho replace QuickBooks?

No. HubWho is built to handle agency-specific billing (subscriptions, ACH collection, client portal, margin tracking) and exports to QuickBooks via CSV. It isn't a general ledger or tax-prep tool, and it's currently pre-launch with early access by request.
