Pricing

Transparent by design.

Three published rates, plus a custom model: hourly support and fixed-price projects for engagements from ad hoc to 12+ months. The longer you commit, the lower the published rate. No hidden fees. All prices are exclusive of VAT — EU reverse charge applies for cross-border B2B transactions.

Per hour · published tiers or custom engagement

Three published rates, set by how long you commit, plus a custom model for 12+ month engagements. Your agreed rate applies to support and fixed-price projects alike — across the agreed scope.

We start with a free assessment: a conversation to understand your needs and see whether we are a good fit for each other. Neither side is obliged to proceed. Detailed technical investigation starts from €800 (one day), with scope and price agreed before proceeding.

Separate costs Licences, cloud or hosting, production infrastructure, travel and dedicated test environments require separate written agreement
Notes
  1. Detailed technical investigation examines code, logs or architecture and starts from €800 (one day). We agree its scope, deliverables, time limit and price, and obtain your approval before chargeable work starts.
  2. You receive written findings covering risks and dependencies, options, a recommendation and a scoped estimate. You keep these findings whether or not you commission further work.
  3. For systems we already understand, we use existing knowledge and documentation to identify any gaps. We agree only the investigation needed to scope the work; familiarity does not replace necessary checks.
  4. Quarterly and Semi-annual require at least 40 reserved hours per month. This minimum is non-negotiable.
  5. Reserved capacity is limited; commitments are accepted in order of signing.
  6. Custom engagements are for 12+ month projects that need a tailored scope, delivery plan, capacity and budget. They do not imply unlimited work or a rate below €70 per hour. Capacity is typically around 120 hours per month, with the exact capacity and maximum agreed in the contract.
  7. Response times, service levels, and expenses are defined in the Master Service Agreement; scheduling, scope, and deployment responsibilities in each Statement of Work.

Engineering Support

Remote · billed by the hour

Escalation support for industrial software systems — the level your own team or vendor calls when they are stuck: incident investigation, root cause analysis, hotfixes, workaround guidance, documentation, and technical exploration.

Out-of-hours 1.5× your rate, on written request — outside 08:00–18:00 CET/CEST on weekdays, at weekends and on Bulgarian public holidays
Emergency work Subject to availability at the applicable rate, with no standby or guaranteed response time

Project Engagement

Fixed price = estimated hours × your rate

Refactoring, new features, migrations, and integrations. Agreed technical investigation, where needed, informs the hour estimate; multiplied by your rate, it is the fixed price — written in the Statement of Work, item by item, before work starts.

The project consumes its estimated hours, not the hours actually worked. A project of at least 40 hours per month over three months or more earns the Quarterly rate; a six-month commitment may use the Semi-annual rate when agreed in writing.

Scope can change without a new Statement of Work. You may swap any item not yet started for new work of the same estimated hours; the price stays the same. Work that adds hours is agreed in a short written change note — the added hours × your rate — and approved before it starts.

If Imbra's estimate was too low, Imbra absorbs the difference.

Notes
  1. A day is 8 hours.
  2. For a reserved-capacity engagement, a fixed-price Statement of Work may allocate part of the paid monthly reservation to the project. Those hours are not invoiced again; the Statement of Work identifies the project allocation and remaining support capacity.
  3. Projects outside reserved capacity are quoted and invoiced separately. Additional work requires written approval and remains subject to availability.
