What the Yuki connector does
StockFlow is built for warehouse operations—scanning, receiving, multi-location stock, and period-end valuation. Yuki is cloud accounting used by SMEs and accountants in Belgium and the Netherlands. The StockFlow ↔ Yuki connector keeps those roles clear: ops in StockFlow, books in Yuki.
Version 1 focuses on the month-end job accountants care about most for stockbeheer: take stock value at a date and book the change into the right ledger accounts via Yuki’s ProcessJournal webservice.
- Webservice Access Key connect (BE or NL API region)
- Map inventory asset + stock-variation GL accounts
- Push valuation delta from Analytics → Stock Value at Date
How to connect
In Yuki, generate a Webservice Access Key for the domain or administration StockFlow should reach. In StockFlow, open Settings → Integrations → Yuki, paste the key, choose Belgium or Netherlands, pick the administration, and save inventory and variation GL accounts (for example 3xxxx and 609xxx—confirm with your accountant).
Generate a Stock Value at Date report with your preferred method (Average, FIFO, or LIFO), then choose Push to Yuki. The first push books the full inventory value; later pushes book only the delta so you do not double-count.
- Generate a Webservice Access Key in Yuki for the correct domain/administration
- Settings → Integrations → Yuki in StockFlow, paste the key and pick BE or NL region
- Select the administration and map inventory + stock-variation GL accounts
- Run Stock Value at Date with your accountant-approved valuation method
- Push: the first push books the full value, later pushes book only the delta
If a push fails or the numbers look wrong
A rejected push is usually one of three causes: the Webservice Access Key expired or was revoked in Yuki (generate a new one and re-paste it under Settings → Integrations → Yuki), the wrong region was selected (Belgian administrations use api.yukiworks.be, Dutch ones api.yukiworks.nl—mixing them up fails authentication), or a mapped GL account was closed or renumbered since the last push (re-map it before retrying).
If the booked amount looks off, remember pushes are delta-based: the entry reflects the change since the last successful push, not the full stock value, unless it is the very first push on that administration. Compare against the Stock Value at Date report used for the previous push, not the current one, when reconciling.
What v1 does not replace
StockFlow does not replace Yuki invoicing, payroll, VAT returns, or bank reconciliation. Product catalog two-way sync and scheduled automatic pushes are out of scope for v1—CSV valuation export remains available as a manual fallback.
Accountants managing multiple client administrations should treat each Yuki administration as a separate connection with its own Access Key and GL mapping—StockFlow does not currently apply one mapping across multiple administrations, since chart-of-accounts numbering commonly differs client to client.
