Payment plan software that tracks every installment on the invoice.

For a service business that splits bigger projects into installments, Workspace369 puts the payment plan on the invoice next to the client record from Specialist at $149 a month (10 seats), while deposits and retainers and recurring invoices are on every plan from $29. Our guide to setting up payment plans for clients walks through the terms to agree first.

A payment plan helps a client say yes to a bigger project, as long as you can see what has been paid and what is due next. In Workspace369 installment plans sit on the invoice itself, next to the client record, with online card payments through Stripe.

Why payment plans get messy

Installments live in a spreadsheet

Tracking who paid which installment outside the invoice means the balance on the invoice is always out of date.

Late installments go unnoticed

Without a clear due date per installment, the third payment slips and nobody follows up.

Clients have to re-enter card details

Asking for the card every month adds friction to every installment.

True all-in-one system

It beautifully combined my CRM, team calendar, and billing tools so I could finally stop paying for a bunch of separate software subscriptions

Best app for my construction business

Great app. This app solved all my needs! Not only did it help, but it is cheaper than other apps. I highly recommend this app if you want to start organizing and automating your business on another level. Also love the design
