Clientary takes the repetitive work off your plate.
Billing, reminders, and follow-ups happen on their own.

Every service business has the same chores: send this month's invoices, chase the late ones, bill the deposit once the contract is signed, log the standing weekly meetings. Set each one up once and Clientary handles it on schedule, with your team told about anything that needs a person. Try us for Free.

How billing automation works

Choose what to automate

Turn on reminders, set up recurring schedules, and mark which proposals and estimates should invoice on their own.

Let it run

Clientary handles each one on schedule, every day, whether or not anyone is logged in.

Step in only when needed

Your team hears about a failed charge or anything else that needs a person.

What runs on its own

From the first signature to the last payment, here's what Clientary does without being asked.

From yes to invoice

Invoices that create themselves

  • Invoice on estimate acceptance
  • Invoice on contract or proposal signature
  • Proposal invoices use the packages the client chose
Billing

Recurring billing on autopilot

  • Send, save as draft, or autopay on schedule
  • Eleven billing intervals, weekly to every two years
  • Pause, skip, or run early when plans change
Getting paid

Reminders and late fees

  • Overdue reminders once or every 3 to 30 days
  • Late fees charged once, daily, weekly, or monthly
  • Payment receipts emailed to clients
Retainers

Retainers that refill

  • Top up automatically when a balance runs low
  • Invoices draw down the retainer balance
  • Balances reconciled every week
Time

Recurring time

  • Standing meetings and fixed work logged for you
  • Pause, resume, or skip a week
  • See committed hours per person in reports
Your team

The right heads-up

  • Notices when documents are viewed, signed, or paid
  • Alerts when an autopay charge fails
  • Reminders for drafts, due tasks, and expired estimates

Hours back every month

No more month-end invoice marathons or awkward follow-up emails. The routine work is done before you sit down.

Get paid sooner

Invoices go out on time, clients get gentle reminders, and saved payment methods are charged on the due date.

Nothing slips

Every signed proposal gets its deposit invoice, every retainer gets billed, and every overdue invoice gets a reminder.

Synced to your books

Invoices, payments, and customers sync to QuickBooks Online in the background. See all integrations.

Ask your AI assistant

For everything else, connect Claude or ChatGPT and ask for what you need in plain English.

You stay in control

Every automation is opt-in. Turn on what helps, leave the rest, and change your mind anytime.

Users love Clientary on G2

Most of the time I'm paid within minutes of sending an invoice because it's so easy for someone to check that task off their list. Obviously I like this software, but most importantly to me - my clients like it.

With recurring invoices, custom templates, time tracking, expense tracking, automated invoice reminders, and so much more, the toolkit they offer has kept us organized and hugely simplified our bookkeeping. I can't count how many times our clients have asked about our 'amazing' invoicing system.

When searching for a client management and invoicing system we researched all the tools for SMBs on the market and tested them out, and Clientary was our hands down choice for ease of use and the ability to easily customize client-facing documentation. And of course the very reasonable subscription fee. As they say themselves, "all the functionality we need, and none that we don't."

Frequently asked questions

What can Clientary automate?

Recurring invoices, autopay on saved cards and bank accounts, payment reminders, late fees, payment receipts, retainer top-ups, recurring time entries, and invoices that create themselves when a client accepts an estimate or signs a contract or proposal. Integrations like QuickBooks sync in the background.

How do automatic payment reminders work?

Turn on reminders once and Clientary emails clients about overdue invoices on the cadence you choose: just once, or every 3, 5, 7, 14, or 30 days until the invoice is paid.

Can an invoice be created automatically when a client signs?

Yes. Turn it on for a contract, proposal, or estimate and the invoice is created and sent the moment the client signs or accepts. For proposals, the invoice uses the packages the client chose.

Will I know when something goes wrong?

Yes. If an autopay charge fails, the invoice is left as a draft and the right people on your team are told right away. The same goes for an automatic invoice that can't be created.

Is there a free trial?

Yes. 14 days, no credit card required.

Do I need Zapier to automate my billing?

No. Recurring invoices, autopay, reminders, late fees, and automatic invoices are all built into Clientary. Zapier is there when you want to connect other apps.
