We prepare the system for peak load: find the bottlenecks, remove them and build in headroom for growth. And you hear about possible problems from monitoring, not from clients.
These are the situations people come to us with most often. Different tasks, one mechanic: we work through the process, find the bottleneck, automate what eats up your time and hand it over working.
“Requests come into chats and get lost, we count everything in Excel.”
Intake with validation, a record in the CRM and a notification to the person responsible.
“Payouts and reconciliation are done by hand — and there are mistakes.”
A settlement module with rules, an operation log and export to your accounting.
“Staff repeat the same action a hundred times a day.”
An internal tool built around the actual process, not around a generic CRM.
“We have the data but no reporting.”
A dashboard and scheduled reports that land where the team already works.
“Under peak load the service falls over and we hear about it from clients.”
Profiling, queues, caching and idempotency — plus monitoring with alerts before users notice.
“There is a system, but every change means two weeks and a new invoice.”
An audit, documentation and a handover so the code stops being a hostage situation.
After a free 30-minute conversation we pick the work format that best fits your task.
01
Fixed-scope project
There is a specific task or set of tasks with a clear scope. We estimate the work before we start and agree on a fixed price and deadline.
You get
A clear scope of work, a fixed price and an agreed delivery date.
Payment
After the result is accepted.
02
Stage-by-stage development
There is an idea or a larger project, but not all features and requirements are clear at the start. We split development into separate stages and move from one result to the next.
You get
An agreed scope, a fixed price and a delivery date for each stage.
Payment
After the result of each stage is accepted.
03
Start with a small task
There is no need to start with a big project right away. We can begin with a small task so you see in practice how we work, how we approach the task and how we communicate during development.
You get
A first finished result you can use to judge our work and our approach to development.
Payment
A fixed price agreed before work starts. Payment after the result is accepted.
Which format to choose? It depends on the task. On the first free call we will go through the scope and suggest the best option.
The exact cost can be determined once we have gone through the task, its scope and the possible risks. After a free 30-minute call we prepare an estimate within 2–3 business days: scope of work, timeline, budget range and the main risks. The document stays with you — even if you decide to build the project with someone else.
02
We do not have a spec. Is that a problem?
No. We start most projects without a ready spec. First we look at how the process works now, what needs to change and what result the business should get. Based on that we define the scope of work and prepare a description that development can start from. If you already have a spec, we will review it and tell you straight away whether it has enough information to start.
03
Who owns the code?
You do — from day one. All the code is kept in your repository, and servers and third-party services are registered on your accounts from the start.
04
What if we do not like the result?
We work in stages, and each stage is paid for after the result is accepted. If the result does not meet the agreed requirements, we rework it until it is accepted. You pay for an accepted result, not just for time spent. On sprints you can stop after any two-week cycle. For a first project we usually suggest a fixed budget per stage — that way you know in advance the amount you are risking.
05
Will you take over an existing system?
Yes, but not blindly. We start with an audit: we read the code, find the bottlenecks and the risks, and say honestly whether it makes sense to keep it or rebuild the weak part. Taking over legacy without an audit is how deadlines get missed, so we do not do it.
06
Our service falls over under load. Can you fix it?
Yes. First we work out why the system cannot handle the load and find the specific bottlenecks. Then we show what exactly needs to change, in what order and how much it will cost. We do not suggest rewriting the whole system if changing individual parts of it is enough.
07
How do you handle financial data?
We build the system so that only the people you have given access can reach financial data, operations can be verified, and important information can be restored if something goes wrong. For payments we build in protection against double charges, and for data — backups with tested restore. We are responsible for the technical implementation. Legal and regulatory requirements stay on your side.
08
Who supports it after launch and what does that cost?
After launch we are responsible for fixing defects that are our fault. After that you can stay with us on monthly support with an agreed response time, or hand support over to your own team. We hand over all the necessary access, documentation and instructions together with the project. The cost of support depends on the scope of work and is agreed separately.
09
Do you work under a contract with an EU legal entity?
Yes. We work under a contract with legal entities in Ukraine and the EU. We sign an NDA if needed — the template is sent right away. Documents for payment and closing the work are issued in the usual way.
10
Why do clients choose Vezko?
You talk directly to the developer who works on your project. We estimate the task for free before we start. We work in fixed stages and show results every week. Code, access and data stay with you from day one. If it is not our specialty, we will say so right away.
11
Can we start working together with a small task?
Yes. There is no need to start with a big project right away. We can take a single task, take it from estimate to result, and then decide whether to keep going together.
12
How long does development take?
After the first free call, within 2–3 business days we assess the scope and complexity of the task and set a preliminary development timeline. If new features are added or the agreed requirements change during the work, this may affect the timeline and cost of the project.
