On schedule
Set your own schedule, write your own emails, change the tone any time. Uku runs it. Your team doesn't touch it.
1 year with Uku and we can serve 38% more customers. Couldn't imagine life without Uku.
Uku is simple and intuitive and covers anything we might need from a work management system — from tracking time and managing tasks to billing. It has increased efficiency and visibility throughout our team.
I'd been looking for a practice management solution for my accounting firm for years. Uku was the answer to our problems.
Uku's team is very helpful in coming up with solutions. In our company, Uku has brought the client closer to accountant while giving both the accountant and management an overview of how much time is spent on what kind of work or communication.
Every question we hear about the SmartAccounts integration — and the answer is always the same.
Enter your SmartAccounts email and password in Uku Settings & Apps. Then add per-client API keys (public + secret) inside SmartAccounts for each client you want to sync work volume data.
One-way: SmartAccounts → Uku. Customers, addresses and registry codes flow from SmartAccounts into Uku. We deliberately don't push client edits back — your books stay the single source of truth.
From SmartAccounts → Uku: customers, products, transaction counts (documents, entries, invoices, bank entries), payment status. From Uku → SmartAccounts: invoices, line items, VAT rates, due dates. The "What syncs" section above shows the full picture.
Yes. This is the killer feature of the SmartAccounts integration: SmartAccounts reports the number of documents, entries, and invoices per client per month, and Uku uses those numbers to bill your volume-based contracts automatically. Stop running count spreadsheets.
Connecting SmartAccounts and importing your client list takes under an hour. Setting up per-client API keys takes a few minutes each. Mapping your services to Uku contracts takes 30–60 minutes. Our onboarding team will sit on a call with you and do most of it.
No. Nothing leaves Uku until you hit send. There's no background sync running in the dark. You stay in control of every invoice that lands in SmartAccounts.
