The same platform underneath, not a bolt-on
Invoicing runs on the same core as every other module — the customer portal shows clients their invoices alongside their quotes, the workflow builder can chase or notify on payment events, and every action lands in the shared audit log.

Invoicing Software That Chases So You Don't Have To
Late payment is a UK small-business tax. The work is done, the invoice is sent, and then someone has to remember to chase — politely, repeatedly, in writing. Most owners either do it late or don't do it at all.
OpSemble sends the invoice with a Stripe payment link, then runs the dunning for you: scheduled reminders, escalating tone, late fees where you've configured them. Recurring billing handles retainers and subscriptions. Quotes accepted in CRM convert to invoices without re-typing, and payment status is visible to whoever talks to the customer — not just whoever runs the books.
It's £8 per user/month, and "user" means someone raising invoices — the whole company doesn't pay for the finance function. Pair it with Projects to invoice from tracked time and milestones.
Frequently Asked Questions
Does OpSemble Invoicing take payments?
Yes. Invoices carry a Stripe payment link so clients can pay by card straight from the invoice, and refunds can be issued from the same screen if you need to reverse a payment.
Can I set up recurring invoices?
Yes. Set an invoice to repeat weekly, monthly or annually — OpSemble generates and sends it automatically on schedule, no manual re-entry.
Does it handle overdue invoices?
Yes. Configurable dunning sequences send reminder emails on a schedule, and you can apply late fees to invoices that stay unpaid past their due date.
Can I invoice clients in a different currency?
Yes. Invoices support multiple currencies, so you can bill international clients in their own currency rather than converting everything to GBP.
Does Invoicing connect to the CRM?
Yes. When a CRM quote is accepted, convert it straight into an invoice in one click — line items, pricing and the customer record carry across automatically.
