Uku → Tripletex
Invoices (as orders)
Your team's tracked time and contracts become invoices in Uku. Review, approve, and they land inside Tripletex as preliminary invoices (orders) — header, line items, MVA, due date.
Uku finds the 15–30% of revenue your Tripletex invoice can't see.
Your team tracks the work. Uku turns it into invoices Tripletex gets the same day. No spreadsheets, no missed minutes, no end-of-month panic.
Tripletex holds the books. Uku runs the practice. Here's exactly what moves between them — and which way. No black boxes.

Uku checks Tripletex once daily for payment updates. Paid invoices close the loop automatically.
Daily sync. Partially paid invoices show as unpaid. Manual refresh available.
How it works
Go to Settings & Apps → Tripletex. Paste your Tripletex employee token. Clients flow in under a minute.
Pick the services, set the rates. Uku starts collecting time for you.
Review, hit send. It lands in Tripletex as an order — line items, MVA, due date. Invoice number updates within 24h.
Paste your employee token and Uku pulls every active customer from Tripletex. Name, invoicing email, address, organisasjonsnummer — ready for work.
Customer moved? Address changed? Re-sync any time. Your books and your practice stay in lockstep — without anyone chasing it.

Build a contract once. Uku pulls in your team's tracked time, fixed fees, and volume entries — and drafts every invoice for you. The work that was lost in spreadsheets gets billed.
Mix time, fixed, volume, and item-based pricing in the same contract. Set minimum time and rounding rules. Your Tripletex MVA codes are already loaded — no double setup.

Review the draft, hit send. Uku pushes the invoice into Tripletex as a preliminary order — header, line items, MVA, due date. Tripletex assigns the final invoice number within 24 hours.
Tripletex marks it paid? Uku picks it up in the daily sync. No double entry. No reconciliation. No spreadsheets in the middle.

Automated Debt Reminders
Tripletex knows which invoices are paid. Uku knows the rest. So Uku sends the reminders — politely, on a schedule you set.
Set up two reminders or five. Different templates for 2, 7, and 14 days overdue. Your team stops chasing money and goes back to actual work.
On schedule
Set your own schedule, write your own emails, change the tone any time. Uku runs it. Your team doesn't touch it.
