KSeF is live. Your team is firefighting it daily. We can stop that this month.
Mandatory KSeF went live on 1 April for VAT-registered businesses (and 1 February for the largest). Every faktura VAT issued by a Polish business now flows through the central registry, and biura rachunkowe are absorbing the operational hit for hundreds of clients at once. Manual reuploads. Failed XML validations. Clients ringing asking why their invoice never arrived. 3DH delivers a 4-week recovery sprint that stops the daily firefighting: Microsoft 365 tenant rebuilt for KSeF, intake automated, JPK CIT workflow configured, team trained in Polish. The firms that get this right in May and June keep their margin. The ones that do not will lose clients by Q3.
The KSeF rollout symptoms you already recognise
Failed validations every morning
Structured XML is unforgiving. Missing fields, wrong NIPs, mis-typed counterparty data. Your team is hand-correcting each one and re-submitting through the central registry. That is hours a day for the next year if nothing changes.
JPK CIT stacked on top
Structured corporate income tax reporting is the second wave. Same data, different format, different submission window. The practices that automate intake, classification, and validation keep their margin. The ones reconciling by hand are already losing it.
Clients ringing every hour
CEOs of 5-50 person Polish SMBs are not reading Ministerstwo Finansów specs. They are calling you to ask why their invoice never landed. The firm that absorbs this with one steady process keeps the relationship. The firm that panics loses clients by Q3.
What we deliver, week by week
- Week 1
Audit your current KSeF reality
We sit with your team for two days and watch the actual workflow. Where the manual re-submissions happen, which client accounts are causing the most failures, which validations keep breaking. Identity baseline, mailbox hygiene, SharePoint structure for client folders, Teams configured for the practice. Copilot license review and CSP optimisation if you have not migrated yet.
- Week 2
Intake automation and validation pipeline
We deploy the invoice intake pipeline: shared client inbox monitored, PDFs and XMLs extracted, structured data validated against KSeF requirements before submission, anomalies routed for human review with the missing field flagged. Native Polish throughout. Built on Microsoft 365 with Claude reasoning for the parts Copilot does not handle.
- Week 3
JPK CIT workflow and team training
Structured CIT reporting workflow configured ahead of the next submission window. Adoption training in Polish for each role: księgowi, asystenci, partner. SOP documents written for the practice. Copilot prompts that work for your specific client base.
- Week 4
Handover and retainer setup
Run the system on real client data for one week with you on the call. Document everything. Set up the monthly retainer that keeps it running, watches for KSeF specification changes from Ministerstwo Finansów, and adds the next workflow when you are ready.
€8,500 fixed. €1,200 monthly to keep it running.
The 4-week sprint is €8,500, paid 50% at kickoff and 50% at handover. The retainer is €1,200 per month after handover, 12-month term, cancellable at 60 days notice. The retainer covers KSeF specification monitoring, monthly review of the workflow, addition of one new automation per quarter at no extra cost, and PL-language support with a 24-hour response window.
Microsoft 365 licenses are billed separately through our CSP. We optimise the licence mix as part of the sprint at no additional cost.
Stop firefighting. Start running.
We take one biuro rachunkowe per month to keep delivery quality high. First week of every month. If your practice has 8 to 50 staff and your team is still hand-correcting KSeF submissions, we should talk this week.
