We build the best solution together.
The system is yours to shape, and shaping it is a normal part of running an accounting firm. Whether your own developers do the work or ours do, you always have someone who knows the engine sitting on your side of the table.
Your developers, full access
Open APIs, documentation and a development environment, so your own team can build views, workflows and integrations without asking us for permission, or paying us to do it.
Our team, whenever you want
Need something built, extended or migrated? Our developers work at project or hourly rates agreed in advance, as an extension of your team rather than a support queue.
Ongoing development together
A named contact, regular reviews and a shared roadmap. What you need built shapes what we build next, you are not waiting behind every other customer.
Customising the engine is not an exception, it's the point. Most customers keep developing theirs for years, and the fixed licence price doesn't change while they do.
Kirjuri, the knowledge service behind good bookkeeping.
We also build Kirjuri: the reference service Finnish accounting professionals use every day. Posting instructions, guides and Kirjuri chart-of-accounts templates in one place, kept current so the answer is there when you need it.
Visit kirjuri.fi
kirjuri.fi Posting instructions and guides
Practical, up-to-date instructions for the situations that actually come up in day-to-day bookkeeping.
Kirjuri chart-of-accounts templates
Ready-made, maintained chart-of-accounts templates you can take straight into use.
Always current
Maintained continuously as legislation and practice change, no more hunting through outdated PDFs.
Kirjuri is built by the same team as Accounting.dev, the same knowledge feeds the engine's country knowledge banks.
Work out what your current system will cost you five years from now.
