Internal business systems
Software for how your company actually takes orders, prices them, schedules the work and gets paid.
Everything we automate and build
Ordinary software does the work that follows clear rules: order entry, invoicing, payroll. AI makes the simple decisions instead of your specialists and hands them the complex ones, with the reason
Automating with us means using AI for the main things, where something has to be understood, weighed and chosen. The rest is done by ordinary software built to work together with AIVitalii Buga · Founder, Zen Software
A web application in place of a folder of Excel files validates and prices every order line as it is typed

Orders from the largest dealer come straight from its app; the others are entered once, and the system prices each shade
We do not add AI where a rule will do
A paid analysis and a written specification: what to build, what it will cost, in what order. Priced before it starts. The document is yours.
How we workOver 12 years of software engineering and management experience running back-office projects for cloud providers in the U.S. The team has delivered order intake, pricing and production systems for several window-treatment businesses and several AI SaaS projects.
About the companyUpwork clientWow, wow, wow. Vitalii was the best freelancer I have used. So dedicated, so detailed and never, never gave me a hard time even when he was right to do so. A real friend and superb coder, professional. I can't recommend him highly enough!
Upwork clientVitalii is one of the best front-end freelancers that I have worked with. He is always at the top of my list when I need some help with projects. Very knowledgeable, friendly and easy to work with. Very happy, as always.
Upwork clientAbsolutely impressed with his abilities and work ethic. As a programmer myself, I needed to outsource some workload for a personal side project. I found that Vitalii was knowledgeable and very good at what he does. Also he speaks/writes fluent English, which was super helpful. I certainly will be using Vitalii again on future projects. He has earned my trust. He was actually the 2nd person I hired for this job. The first one could not complete this task as needed (even though they had a compelling resume).
Anyway, I can't say enough good things about my experience with Vitalii. If you are looking for someone who can actually do what they say they can, is easy to work with and completes projects on time, I recommend him fully.
Upwork clientHonestly the best dev that I use here at Upwork. He is without a doubt my favorite and preferred programmer. His work is clean, logical and on time. Beyond that he usually identifies missing needs and features in projects that I had not considered, which is massively helpful.
Upwork clientHe is always great to work with and always goes the extra mile. Always happy with his work and communication.
Upwork clientAmazing work as always!
Tell it what you need built. In a few minutes you will have a rough estimate of cost and timeline, with no forms and no waiting
Software for how your company actually takes orders, prices them, schedules the work and gets paid.
Everything we automate and build
Your CRM, accounting, ERP and messaging tools pass data to each other, so nobody copies it by hand.
Everything we automate and buildWe sit with your employees and follow how an order, an invoice or a request actually moves.
Every step, tool, hand-off and exception goes on one map. Most teams see their whole process for the first time.
We remove the steps that exist only because two tools could not pass data to each other.
Work that follows fixed rules becomes software, and every step it takes is logged.
AI takes the cases where something has to be understood, weighed and chosen: a PDF, an email, a photo. Only those.
We compare time and errors before and after, and fix what the numbers point to.
A paid analysis and a written specification: what to build, what it will cost, in what order. Priced before it starts. The document is yours.
Hourly, invoiced monthly. For integration work and anything where the scope moves.
For a defined stage, split into acceptance milestones with written criteria for each.
A 30-minute call about one process in your business. We will say where automation fits and where it does not
